8:15 AM - 8:45 AM

As the industry gathers to “Discover the Opportunities of Light,” Lawrence Lin, CEO of LEDVANCE, will start the conference by talking about new LED advancements for full spectrum lighting which delivers on the potential of positively influencing a person’s health and wellbeing.  Lin will share how there are new opportunities for full spectrum LED light that can closely match natural light for an improved sleep/wake cycle and true, accurate colors without sacrificing lumen performance and efficacy.  LEDVANCE is a leading global supplier of LED lighting products, selling a wide range of lamps, luminaries and smart lighting systems in over 140 countries.

Keynote Speaker: 

Lawrence Lin
8:45 AM - 9:15 AM
Beyond the instruments of lighting and their implementation, what are the purposes of light?  How do we design light and lighting to create behavior, perception and performance?  What exactly is it that an end user can ask for from light?  As the lighting industry becomes ever more capable of manipulating light through optics, control, objects, we must ask ourselves “to what end?”
A focus on numerical performance, while important, misses the real reasons that our clients build projects.  In this lecture, Thomas Paterson explores how to structure the very brief for which lighting is created – and defines how tools may be selected.

Keynote Speaker:
Thomas Paterson
9:15 AM - 9:45 AM

This presentation with begin with an overview of the packaged LED and general lighting markets, focusing on their growth over the past year. It will then provide a detailed five-year forecast of these markets, including some exciting growth markets in niche verticals such as lighting for horticulture.

8:30 AM - 9:00 AM

In the 1990’s, it was a heady time for prediction and prognostication about energy. The lighting industry established goals to be reached in the foreseeable future, calling their plans “Vision 2020” as a roadmap for the evolution of lighting.   The US Department of Energy entered the scene with little clue (along with the rest of us) of what would become of lighting in the next 20 years.  Energy codes including ASHRAE/IES 90.1-1999 and California Title 24-2001 were trying to set the pace, but most of the industry did not know what a driver was and could not imagine a future without “super T-8” fluorescent lamps.

But a sharp turn was approaching.  By 2012, the emergence of two complimentary technologies dramatically altered the entire lighting industry and quickly changed the slope of the energy curve for lighting. White light LEDs and control electronics replaced historic technologies in less than seven years.  Now, in 2020, lighting is no longer a major energy user in new and retrofitted buildings. This exceeds the wildest predictions and dramatically alters the emphasis of the lighting industry.

Well, here we are in 2020 and bluntly, the energy era for lighting is completely over.  Our work is done.  So, what’s next? This keynote offers a visionary roadmap for continued growth in the lighting industry in ways not imaginable 20 years ago.  Some are obvious, others will be a surprise. Come and hear.

Keynote Speaker:

Jim Benya
9:00 AM - 9:30 AM

Now that LED energy efficiencies are nearing their maximum values, and lighting is now so energy efficient that energy drivers no longer play a strong role in SSL adoption, does that mean the SSL revolution is over? This talk will review remaining directions for SSL evolution, and focus on some new drivers for LED lighting design and applications that might help keep the revolution going. Beyond the frontiers of Lighting for Human Well Being and LiFi for 5G, this talk explores topics like Dynamic Occupant Centric Lighting (and the future of lighting controls) and how the evolution of micro-LED displays can enable a future fusion of Illumination and video technologies.

Workshop 3: What to Build and When to Build it. Scenario Planning and Decision Support Workshop for Lighting and Technology Companies
8:00 AM - 5:00 PM

Lighting and technology companies today face complex challenges in planning products and systems including: 1) the intrusion  of IT and big data into many industries, especially lighting; 2) rapid change in technology following a period of many decades of relative stasis in lighting; 3) incomplete understanding of rates of adoption and replacement; 4) a business culture that assumes “disruption” and blitzscaling that work for IT and consumer electronics also work for lighting; and 5) lack of perspectives on and tools for envisioning and managing the future of lighting, controls, and building technology.

This daylong workshop combines insights and tools from diverse sources: scenario planning; advanced midrange crowd-sourced forecasting; and behavioral economics. Workshop registrants will receive a pre-workshop primer with preparatory material, including macro scenarios that the speaker team has developed. The workshop begins with presentations from the panel that provide relevant ideas, case studies, and examples of improved decision making and successful strategy in different companies. Then teams are formed, each is given a specific hypothetical product roadmap with one or more critical decisions and challenged to think it through, creating 3-4 different scenarios that are used to test assumptions, test ideas, and set metrics for success. Each team then presents its scenarios to the speaker panel, who pose as investors interested in funding the project and offer comments and feedback.

The workshop is designed for product managers, engineers, designers, sales and marketing professionals, specifiers, technical advisors, and C level company officers, consultants, and investors in lighting and electronics manufacturing companies who need strategic decision support tools to help manage technology development and integration, sales and marketing, operations, logistics, SKU proliferation, certifications, code compliance, and supply chain coordination.

Learning Objectives

1. Improve product roadmap decisions in assessing and implementing new technologies, allocating development resources, investing, marketing, and product management

2. Use new perspectives on changes in adoption and replacement of components, systems, and infrastructure of communications, controls, lighting, and power distribution

3. Crowdsource collaborative networks with diverse views that test assumptions, key questions, roadmaps, and strengthen forecasting

4. Stimulate deep imagination and visualization by understanding, then moving beyond the limits of the past to actively creating the future

Workshop 4: Obtaining and Litigating Patents in the LED Industry
1:00 PM - 5:00 PM

The first half of the course will focus on obtaining patent rights. Using LED industry hypotheticals, you will learn how to maintain patent rights by being diligent. We will also discuss what research should be done prior to filing for a patent, and how to decide what kinds of things to patent and what things should not be patented. The second half of the course will focus on patent litigation with a particular emphasis on the LED industry. With the amount of litigation in the LED industry steadily rising, having a basic understanding of litigation is crucial for lighting companies both large and small. Topics to be covered will include: recent trends in patent litigation; patent holders in the LED industry embarking on litigation and licensing programs; and the mechanics of litigating patents in the US including what to do and expect when sued for infringement.

Speakers:

Where's the Money Going Next?

The Investor Forum to be held in conjunction with Strategies in Light 2020 will be updated in a new format to reflect the current dynamics in the LED and lighting industries.  While major component suppliers and large lighting companies struggle to maintain profit margins in light of competition from Asia, tariffs, and product commoditization, small-to-midsize companies are looking for M&A opportunities, mainly through acquisition by private equity firms or larger companies.  Many new companies have appeared on the scene that focus on fast-growing vertical markets, including horticultural lighting, lighting for health and well-being and connected lighting.  Other companies are focused on new opportunities in technologies beyond the traditional LED component markets, including UV LEDs and micro-LEDs.

In addition, Reid will discuss the tradeshows that support the industry and how they are evolving.  He will outline new technologies as well as address niches that can are still quite profitable.

Speaker:

11:30 AM - 12:00 PM

Due to common factors of all things digital and disruptive, LED lighting and Connected Lighting are following two proven patterns. First, the digitalization of an industry’s core product leads to the five consecutive stages of product evolution - deception, disruption, demonetization, dematerialization and finally democratization. In similar fashion to prior lighting upgrades with respect to quality of light and energy efficiency. The second simultaneous pattern is end user buying habits. These habits are irregardless of product or service and tied directly to their disruptive nature and impact.

There are five distinctive groups that each respond differently to the same technology – innovators, early adopters, pragmatists, conservatives and laggards.

This session will discuss these two patterns in detail, how they impact our industry, what opportunities and challenges they offer and finally discuss solutions learned by other industries that apply to the lighting industry.

Speaker:

Session 2 Panel: Standards for Circadian Lighting
1:30 PM - 3:00 PM

There has been a great deal of research and discussion in the lighting industry regarding the impact of artificial lighting on human health and well-being.  For example, it has been well documented that worker exposure to blue-rich light sources on evening and night shifts disrupts the body's biological clock, impairs performance and sleep, and increases the risk of a variety of medical conditions. Other research has demonstrated the beneficial effect of the use of lighting with proper spectral content on alertness and worker performance in the daytime.  However, until recently there have been no industry-wide standards that address these issues. This panel will review and discuss newly developed circadian lighting standards such as those contained in the American Petroleum Institute ANSI Recommended Practice for Workplace Lighting and those proposed by the UL Task Group on Circadian Lighting.

Speakers:

Session 3: The Future of Market Transformation
3:45 PM - 4:15 PM
This session will cover lighting regulations and incentive programs, reviewing both recent and upcoming changes to the regulatory and incentive landscape. Examples will demonstrate how much the industry is driven by rebates & regulations. Key questions addressed: 1. Recent and upcoming regulations from the US DOE, CEC (CA), and NRCan (Canada) that will most impact the lighting markets. 2. Major trends in utility rebates for residential/retail & commercial programs. 3. Will residential lighting rebates disappear in 2020? 4. What are the major trends in commercial lighting rebates? 5. What are the latest developments with DLC and ENERGY STAR lighting? 6. What are the trends for rebates on controls and horticultural lighting, as well as the associated DLC specs?
 
Speakers:
4:15 PM - 4:45 PM
For many years, California has been achieving lighting energy efficiency savings through its Appliance Efficiency Regulations (Title 20) and Building Energy Efficiency Standards (Title 24, Part 6). While Title 20 applies at the point of sale and Title 24 applies to new construction and alterations, both work in tandem to support California’s lighting market transformation efforts. This presentation aims to provide clarity for market actors on when each regulation applies and how to comply with both. Using a sample project, we'll provide an overview of California’s lighting regulations with a focus on their purpose, applications, certification processes, correlation, and code change updates. Hands-on demonstrations will give attendees the tools to identify the features a lamp needs to meet one or both regulations, and where those compliant products can be found. This training will facilitate industry access to California’s enormous and evolving lighting market.

Speaker:
4:45 PM - 5:15 PM

The lighting market is maturing in terms of LED’s achieving maximum technology levels and replacement product availability.  Demonetization has accelerated this transformation.  The conspicuous changes occurring now involve non-energy benefits of lighting.  Organizations previously focused on the energy efficiency gains made possible by LED conversions are now broadening their criteria to include other aspects of light sources and luminaires.  Market shifts toward lightings integration into IoT/smart cities/connected lighting systems and quantifying the health impact on life forms including humans, animals and plants for horticulture are influencing new requirements in existing market transformation programs.  This is occurring concurrent with the research with the risk of organizations leaping ahead of the science.  This presentation will discuss the trends driving market transformation and will offer a glimpse into lighting’s trajectory into this brave new world while predicting the velocity of those changes.

Session 4: Automotive Lighting
10:15 AM - 10:45 AM

Automotive Head lighting has evolved into complex and intelligent systems with functions such as directional steering and adaptive dimming using technologies like LED, DLP or Laser. On the other hand, new lighting options such as OLED, LED-Strings, Mini-LED or Micro-LED will play a key role in the future in rear lamps as well and open up new design and functional possibilities. Due to the long development history, these systems are the best-developed, most robust, and best integrated photonic systems in today's mobility solutions. Light helps drivers and sensors to “see,” and serves as a medium of communication with other road users. As vehicles become more digitized, they require additional new lighting functions that go beyond the need for illumination. This trend can be seen with the increased use of dynamic lighting effects on vehicles. The complexity of these systems bring new challenges in incorporating the light sources in automotive lights of today.

Speaker:

10:45 AM - 11:15 AM

Intended as an introduction into vehicle lighting, we will investigate the major components of a vehicle lighting system, Its origins, its technology trends, and how this compares to / contrasts with stationary lighting.

Speaker:

11:15 AM - 11:45 AM

Trends in styling and advanced functionality of automotive lighting drive the development of LED light sources along the three vectors of high luminance, miniaturization and function integration.  Freedom of design, often trending towards slim or low-profile automotive lighting systems, is the main driver behind miniaturization and luminance.  New functionalities, such as adaptive driving beam (ADB), and dynamic signaling, require arrays of individually controlled LEDs, which bring challenges with growing complexity to managing optical efficiency and thermal performance. ADB applications require light sources that are an integration of discrete elements to create up to ~100 pixel systems, or as a directly imageable source of 10-50k pixels that are <50um in size. New technologies are needed to enable close placement and interconnectivity, while meeting optical, luminance and thermal requirements of applications.  We discuss the innovation that enables next generation automotive lighting systems and their capabilities.

Speaker:

Session 5: Advanced Concepts in Lighting
1:15 PM - 1:45 PM

The presentation will explore the existing world of new media lighting installations and review some of the players behind the most prominent examples. Show how people can find more inspiration and who can they contact for help with their own projects. Then further explain how to market these types of projects and who's buying them. There would be a discussion of the classes of technologies commonly used to create these installations and a review of how LED technology can be used in new and innovative ways to create spectacular works of art. As well as a walkthrough of the common challenges associated with creating unique installations. The main goals of the seminar are to show the audience at the conference the exploding market for creative uses of LED technology, broadening attendees' perceptions of how LED technology can be used, and how creative designers are repurposing technology from many disparate fields to work together.

Speaker:

1:45 PM - 2:15 PM

Everyone from leading employers to public health officials to educators now realize the built environment has an enormous impact on health and wellbeing. We spend 90% of our time indoors. If indoor spaces don’t provide the environmental conditions our bodies require, our physical, emotional and mental health pays the price. In fact, the spaces we inhabit at work, home and elsewhere may have a bigger influence on our overall health than our lifestyle habits, genetics or medical care.

Cree Lighting will examine the WELL Building Standard guidelines for lighting and discuss the role lighting plays in maintaining proper circadian rhythms, improving mood/energy levels, boosting cognitive function and maintaining a general sense of wellbeing. We’ll review our own research on market perceptions of lighting for wellness, and examine the various ways the lighting industry is bringing the outdoors in to spaces where natural light is impossible or impractical.

Speaker:

Track 2: Advancements in LED and Lighting Technology, Design and Manufacturing

Wednesday, February 12, 2020

Session 1: Component Technology
10:30 AM - 11:00 AM
The continued improvement in LED luminous efficacy has led to devices being driven harder to provide higher luminance, but this leads to more heat in the LED package which has negative impacts on color point stability and lumen maintenance. As the use of chip-on-board (COB) and chip-scale-package (CSP) LEDs continue to grow in lighting, a better understanding of factors impacting color shift behavior and performance will be explored. A systematic investigation of color shift behavior was conducted using LM80 data from major LED manufacturers to assess the impact of material choices in phosphors, encapsulants, and molding resins used in the LEDs. This presentation will focus the value proposition for providing acceptable color stability for COB and CSP LED package platforms and compare them to the behavior seen in high-power and mid-power LED packages. Guidance will also be given on approaches to achieve acceptable color point stability in lamp and luminaire products.
 
Speaker:
11:00 AM - 11:30 AM
We provide a description on the rapidly expanding capabilities of laser light technology, including 500 - 1000 lumen sources with luminance above 1000 cd/mm2 (more than 10x that of LEDs), and with arrays exceeding 10,000 lumens and with a 5 km beam distance. Additionally, we describe novel fiber delivered and fiber emissive white light sources, with simplified maintenance and enhanced thermal management. Lastly, we present spotlight modules that deliver more than 10 giga-bit per second data rates for LiFi communication applications, as well as spatially dynamic beam control, enabling high precision beam shaping. Such laser light sources have applications in portable, architectural, entertainment, outdoor, and automotive lighting.

Speaker:
11:30 AM - 12:00 PM

MicroLED display is an emerging technology with high brightness, wide color gamut, high aperture ratio, and good reliability. In additional to traditional display applications, MicroLED display can be used for innovative display technology.

MicroLED display is composed by tens of microns LED chips on a driving backplane. The LED chips typically use red, green, and blue, but they could also use blue with color conversion material on top of each LED chip to generate full color. And the driving backplane could be passive matrix driving or active matrix driving.

Based on our proprietary PixeLED Display technology, we have demonstrated various new applications, such as borderless transparent display, ultra-high brightness wearable device, and ultra-thin flexible display.

Speaker:

Session 2: Luminaire Technology
1:30 PM - 2:00 PM
Organic Light Emitting Diodes (OLED) are a solid-state lighting (SSL) technology. compatible with standard SSL controls. Full color, bright, thin, diffuse, uniform, low glare, efficacious and long lifetime – OLEDs are competitive today and continue to improve. This excellent lighting experience delivers a solution for the increased attention to healthy lighting and blue light hazard. This talk, in addition to providing a summary of OLED price, performance and roadmap trajectory, will expand on the market forces, application segments, design solutions and growing demand for OLED lighting. A general lighting case study summary will be shared including application efficiency and customer experience. The unique design attributes that are propelling OLED solutions in automotive markets will be discussed. The threshold of box specs is imperative, but it is the OLED design elements and the superb light quality that manufacturers are embracing for solution differentiation.

Speaker:
2:00 PM - 2:30 PM
The inherent tendency to use familiar design means that the full potential of solid-state lighting technology has yet to be realized. LEDs offer a unique opportunity to develop a new class of fixtures of extraordinary design whereby the source and fixture evolve into a single entity. It is a ladder of different scales, and the endpoint is a true systems integration where separate sources, optics, and fixtures are no longer needed while also offering brand new capabilities. The source and the fixture can become a single unit offering greater beam-shaping, enhanced color stability, and lower costs to manufacture.

Speaker:
2:30 PM - 3:00 PM
As lighting manufacturers working with sound absorbing material, this presentation sets the basis of acoustics for work environments. It defines the quality of the sound environments for lighting people as it draws a clear parallel between light and sound. Backed by tangible workplace studies and scientific acoustic test results done over the years, it allows for effective integration for acoustic control in lighting fixture design.

Speaker:
Session 3 Panel: What Can 3D Printing Offer the Lighting Fixture Industry Today?
3:45 PM - 5:15 PM
Experts are predicting that 3D printing will transform the design and manufacturing of parts within the next two decades. In the future, 3D printing will allow us to print novel objects that cannot be manufactured today. Lighting manufacturers are seeking better and more cost-effective ways to produce custom light fixtures and parts in order to be more competitive in the marketplace. In this 90-minute panel presentation, moderator Nadarajah Narendran will lead a discussion with panelists working in the 3D printing field on the performance, speed, and cost issues related to using additive manufacturing for the production of lighting components. The presentation will include an introduction to the promise of 3D printing for lighting fixture manufacturing, followed by a comparison of lighting fixture parts manufactured using polymer and metal 3D printing and traditional manufacturing methods for performance and cost.

1:45 PM - 2:15 PM

High-volume lighting products often require complex and difficult to attach and align optical systems.  These types of systems often require significant assembly labor and can still lack tight position tolerances.  To increase control of light output, precision-placement of engineered optical elements is needed.

CoreLED Systems has developed a family of surface mounted reflectors that provide a variety of beam patterns.  These optical elements can be placed at the same time as the LED on the PCB with standard pick and place equipment.  This keeps the required precise positioning of the optics to the LED in the IR reflow solder process.

This is a considerable cost and space savings at final lamp assembly because it replaces the need for additional components and mounting systems while providing tight tolerances for highly-sensitive optical designs.  CoreLED’s solution is ideal for UV, IR, and visible light LEDs.

Speaker:

2:15 PM - 2:45 PM
Much more attention has been made for the research of micro lens array(MLA) design and manufacturing for applying micro- and mini-LEDs to automotive, biomedical, TV and wearable displays, augmented(AR) and mixed reality(MR), flexible panel lightings, and optical communication. For the development of manufacturing technology for MLA of AR/MR displays with higher resolution and luminance, the repeated optimization of aspheric lens arrays, the development of Ni master mold using electro-chemical methods and unique lens forming device have been carried out to achieve more than 847 ppi resolution on 0.47” display device. This technique has been significantly improved several times to account for the high precision bonding with the quantum dot film for color changing and the second bonding with the front plane. The technology for the evaluation of optical performance of MLA in/outside of device and the alignment technique for each bonding layer have been developed in several proto-types.

Speaker:

Track 3: Connected Lighting and the IoT

Wednesday, February 12, 2020

Session 1: Bringing Value
10:30 AM - 11:00 AM

This session will bring order to the chaos and confusion of determining which connected system is best for you and your client needs. The cacophony of marketing messages and technical complexities across the many digital systems makes it genuinely difficult to determine how a system will or won’t fulfill the lighting controls intent, as well as the Owner’s Project Requirements. This session will provide an agnostic overview of many different types of systems and their respective benefits and gaps, and will offer a functional selection process to support wayfinding to your next connected system.  Value will be discussed and clarified across the ecosystem of the lighting, buildings, energy and real estate industries. 

Speaker:

11:00 AM - 11:30 AM

Smart buildings are an elusive and now almost-maligned concept in the design and construction industry.  Why isn’t every building smart if it is such an improvement?  In this presentation, David Wilts will share his hard-won experience from over 300 smart building projects over the last decade.  Real-world project successes and failures will be shared, as well as the central role integrated lighting control systems can play in the Digital Building of the future.

Speaker:

11:30 AM - 12:00 PM

For new construction and retrofits alike, connected lighting is now a given. It is necessary to meet code, but connected lighting does more than meet code. It opens the door to bring smart sensors and the Internet of Things (IoT) infrastructure into a building because most of this advanced technology is installed through light fixtures. Current technology enables end-users to install the IoT infrastructure now, and unlock the benefits of IoT whenever the time is right. It is critical to ask the smart building questions and weigh the pros and cons during new construction or a lighting retrofit since lighting isn’t typically upgraded for another two decades. Discover the benefits of considering IoT technology during a renovation or new build, what types of technology are on the market, the return on investment of IoT and the pitfalls of waiting.

Speaker:

Session 2: Security
1:30 PM - 2:00 PM
The increased connectivity found in emerging Connected Lighting Systems (CLS) introduces cybersecurity risks that are new to the lighting industry and that must be addressed for successful integration with other systems. While a number of existing frameworks, guidelines, and tests for evaluating cybersecurity vulnerability may apply to CLS in whole or in part, there is currently no mandatory requirement for cybersecurity testing or certification. The lighting industry is currently evaluating the suitability of existing frameworks and guidelines for CLS. This presentation reports on ongoing work that is intended to support these efforts by exploring authentication practices and their implementation in multiple CLS. A set of authentication vulnerability tests was defined and applied to explore the implementation of basic authentication best practices as well as known technology-specific best practices. Tests, test results, and failure conditions will be presented and discussed.

Speaker:
2:00 PM - 2:30 PM
Connected lighting systems are only as good as the application programming interface (API) they’re connected through. The ideal solution uses an open standards-based API to provide interoperability with third-party networks and technologies for virtually limitless IoT applications. Increasingly, it seems everyone in the lighting industry has a connected solution (or two, or more!) But as the connected revolution explodes, are we doing more harm than good? Cree Lighting will discuss the current state of connected lighting on two critical fronts: security and interoperability. Both areas continue to be a top concern among end users deciding to implement a smart building or connected lighting strategy. We’ll examine how the industry overall is combating and/or contributing to these perceptions. We’ll review our own findings and best practices derived from over a half-decade of implementing connected solutions and building out a robust software development partner network.

Speaker:
Session 3: Designing Systems
3:45 PM - 4:15 PM
The speakers will discuss the lessons learned from a field study using two connected lighting systems in an office application. The presentation will contrast the two approaches studied (one sensor per fixture vs. one sensor per group of fixtures) and include the energy savings, response from occupants, facility manager and upper management, and the experiences from the team specifying, installing, and commissioning the systems. The session will end with a review of the top 10 questions to ask before specifying a connected lighting system.

In March this year, the wireless lighting control technology from Silvair enabled a rapid lighting retrofit at the 21,500 ft2 Brussels office of Macq Mobility Management Solutions. It resulted in deployment of a 360-node wireless lighting control network, the biggest office implementation of a qualified Bluetooth mesh lighting system to date. It employs a full range of advanced lighting control strategies - occupancy sensing, daylight harvesting, and scheduling. In addition, it monitors each luminaire’s energy consumption, allowing the efficiency of the introduced strategies to be assessed and optimized over time. As part of my lecture, I want to provide detailed information about the Brussels project - from its design and implementation to results observed and lessons learned. We will discuss how wireless lighting controls can drive energy efficiencies across commercial spaces.
 
Learning objectives:
1. Participants will learn about the practical implementation of the Bluetooth mesh lighting
control technology. I will explain how the system was deployed and what components
were used.
2. Attendees will learn about the commissioning process carried out at the Brussels office -
how long it took and what control strategies were implemented.
3. I will present actual energy consumption data from the Macq headquarters, discussing
how the deployed solution increased the overall lighting efficiency.

Lighting Designers, Interior Designers, and Architects meticulously plan the experience of a space, down to the smallest detail. Yet, when it comes to lighting controls, arguably the part of a lighting design that end users experience the most, we regularly push lighting controls scope off to the Electrical Engineers. On top of that, with the rise of IOT and Connected Lighting, more lighting control systems are being created by people from the tech world, instead of the lighting world. The reality of lighting controls frequently fails to match both the design intent and users' expectations, leading to hacked sensors and missed opportunities. What are we missing by leaving the creation, design, and implementation of lighting controls to others? The lighting design community needs to step up, take control, and maintain the user experience they work so hard to achieve.

Session 4: Wired and Wireless
10:15 AM - 10:45 AM

LiFi’ is one of the commercial manifestations of short-range optical wireless communications using the visible spectrum. LiFi can, but is not always, associated with providing both lighting and communications.  Current research demonstrates visible light communication data rates peaking in the 1-10 Gb/s range usually under controlled laboratory settings. Practical systems designed for commercial deployments are limited to the 10s or 100s of Mb/s or drop the lighting function to realize higher rates.

Due to the short range of LiFi, it typically will require multiple units (access points) to provide data and lighting coverage. Moreover, each AP requires high-speed backhaul. In this talk we consider the practical aspects of system deployment including data egress, data rates, and complementary status to other existing access media.

10:45 AM - 11:15 AM

Bluetooth mesh is increasingly recognized as the protocol of choice for indoor lighting control and IoT. Xicato has been an industry leader, with tens of thousands of Bluetooth controlled lighting nodes, sensors, switches, and IP gateways installed in museums, retail stores, office buildings, residences, warehouses, and restaurants around the world. Major installations include Westminster Abbey, the Smithsonian Portrait Gallery, the Chicago Field Museum, Boston Gardens, Cincinnati Terminal, the Chrysler Building, and the Van Gogh Museum in Amsterdam.

This session presents the various lighting goals, challenges, and solutions implemented in some of these sites, including combinations of automated control based on time-of-day, occupancy and lux sensing, mobile and switch-based control, 3rd-party lighting control and BMS integration. Many of the challenges were inherent to the application of lighting controls in heritage sites and retrofit environments. Some were inherent to wireless networking. But all were addressed using Bluetooth wireless networking.

Session 5: Lighting for Health and Wellbeing
1:15 PM - 1:45 PM

For most building occupants, light has been something we’ve always controlled with a simple flip of a switch, or experienced as a static condition of the space. The convenience of light-on-demand has lengthened our days and shortened our nights. Today we realize, light affects us in more ways than we could have imagined just a few years ago. In this session, we will explore the differences between visual and non-visual consequences of light and how this knowledge is changing the way we consider delivering light to the spaces we occupy.  Additionally, we will discuss the near-term potential of evidence-based recommendations for “better light” along with future possibilities.  
In this presentation, we will:                                          
-Examine the varieties and differences of lighting solutions designed for visual versus non-visual impact
-Compare and contrast the WELLbuilding standard and LRC circadian stimulus as it relates to typical lighting design scenarios
-Explore the potential conflicts between lighting designs optimized for health and well-being, versus optimal energy efficiency
-Identify likely trends and future possibilities surrounding dynamic lighting solutions

1:45 PM - 2:15 PM
The estimation of the potential impact of general lighting in human health and wellbeing is a challenging field of science. A great progress has been done in the last 20 years with the discovery of the ipRGC (intrinsically photosensitive retinal ganglion cells), and the proposal of different functions of merit for their action spectra (such as the WELL Building Standard and the CIE S026:2018). Beyond this, we already proposed a model for the estimation of the melanopic potential of lighting setups, that we refined at LHWC 2018. We go one step further in our approach taking into consideration the energy impact of the melanopic stimulus and how new approaches have to be considered to balance, during a whole temporal window (day, week, year), energy consumption against proper melanopic stimulus. It is not anymore about the “lumen/watt”. It is about proper lighting for human health and wellbeing, without the constraint of current energy metrics.

2:15 PM - 2:45 PM
Designing for street and roadway applications takes into consideration a variety of factors such as visibility, aesthetics, safety, and environmental impacts to name a few. What was first viewed as an energy-saving savior, LED lighting for outdoor and street lighting purposes has been increasingly criticized because of the harsh cool light disrupting neighbors and nocturnal animals. Cree Lighting will examine the shifting public opinion of LED street lighting and consider the possibility of LED returning to the warmer color temperature, and associated visual comfort, of the all but outcast high-pressure sodium light. With this, we’ll review the challenges of providing the proper amount of light and accurate color rendering at such a warm CCT. Is it possible to provide a more comfortable experience for the public without sacrificing driver and pedestrian safety or negatively impacting neighborhoods? With the latest advancements in LED technology and luminaire design, we think so.
