Currently, all of major LEDs companies use a hetero-epitaxial growth to make LEDs. GaN substrates are now available for LEDs in spite of a high price. The performance of homo-epitaxial LEDs should be better than that of hetero-epitaxial LEDs in the view of the crystal quality. LEDs can be grown on a different crystal orientation from C-plain, such as semipolar and nonpolar plains using GaN substrates. Considering about the latest results of high-efficient semipolar blue LEDs with much smaller current and thermal droop in comparison with those of conventional C-plain LEDs, nonpolar and semipolar LEDs would occupy some market share around 2020.

LEDs have gained in a wide variety of applications over the last few years, from back light for mobile device to TV to solid state lighting. The successful adoption of LED for lighting relies heavily on efficiency and cost improvement. In this talk, we will present approaches to achieve 235 lm/W of cool white and 226 lm/W of warm white LED using high voltage design. In addition, we will discuss an innovative design in order to achieve 160 lm/W for an omni-directional warm white light bulb. We believe using these new concepts, the penetration rate for LEDs in lighting will increase tremendously and mass commercialization of LED lighting will be realized in 2013.

Currently, Dr. Jou is the President of Epistar Corporation. His main interests are Metal-organic Vapor Phase Epitaxial (MOVPE) growth of optoelectronic devices and semiconductor device processing. Dr. Jou has authored or co-authored more than 70 technical papers in scientific journals and conferences and holds more than 60 patents in his fields of expertise. Dr. Jou has a Ph. D degree in Materials Science and Engineering from University of Utah and a B.S. degree in Chemical Engineering from National Taiwan University.
The decline in price of LED packages, increased use of mid-power packages, improved designs, availability of a variety of LED packages are some of the drivers that have made LED lighting competitive with other light sources. The increase in the volumes triggered by subsidies and rebates has further reduced prices for the end-users. The feasibility of LED lighting is no longer in doubt. The LED technology used with controls offers potential to save significant energy. The presentation will review some of these market drivers and the challenges in 2012 by application, and forecast the market for 2013-2017.

In October 1962, Nick Holonyak, then a researcher at General Electric’s laboratories in Syracuse, New York, demonstrated the first visible light emission from an LED. Over the next 50 years LED technology made incredible advances thanks to the work of Dr. Holonyak, and many other
outstanding scientists and engineers. To commemorate the 50th anniversary of the invention of the visible LED, Strategies in Light honors several of the pioneers who were instrumental in advancing LED technology, providing the technical foundation for today’s $12 billion worldwide industry that serves multiple applications, including lighting. Honorees include:
Nick Holonyak was Nobel Laureate John Bardeen's first Ph.D. student at the University of Illinois at Urbana-Champaign, where he received his undergraduate and master's degrees and Ph.D. (1954). He created the first visible semiconductor lasers in 1960. In 1963, he again joined Dr. Bardeen, the co-inventor of the transistor, at the University of Illinois and worked on quantum wells and quantum-well lasers. He invented the first practically useful visible LED in 1962 while working as a consulting scientist at a General Electric Company laboratory in Syracuse, New York and has been called "the father of the light-emitting diode". In addition to introducing the III-V alloy LED, Prof. Holonyak holds 41 patents. His other inventions include the red light semiconductor laser, and the shorted emitter p-n-p-n switch (used in light dimmers and power tools). He helped create the first light dimmer while at GE. Prof. Holonyak has received numerous awards for his contributions, including the National Medal of Technology, the IEEE Medal of Honor, the IEEE Edison Medal, the Japan Prize, the Lemelson-MIT Prize, the Frederic Ives Medal of the Optical Society of America, and many others.
George Craford received his MS (1963) and PhD (1967) degrees in physics from the University of Illinois in 1967 working under Prof. Nick Holonyak. He began his professional career at the Monsanto Chemical Company, then in 1979 joined Hewlett Packard, where in 1982 he became the research and development manager of the HP Optoelectronics Division. When Lumileds Lighting spun out from HP in 1999, Dr. Craford was named the company's Chief Technical Officer (CTO). In 1972 Dr. Craford invented the first yellow LED as well as red and red-orange LEDs. At Monsanto, his group developed nitrogen-doped GaAsP, and at HP pioneered development of AlInGaP LEDs and developed AlGaAs and InGaN products. In addition, his team implemented compound semiconductor wafer bonding to create devices with efficiencies exceeding incandescent and halogen lights. Dr. Craford is a member of the National Academy of Engineering, an IEEE Fellow, and recipient of the 2002 National Medal of Technology and 1995 IEEE Morris N. Liebmann Memorial Award, as well as awards from the Optical Society of America, Materials Research Society (MRS), and Electrochemical Society for his LED research.
After studying physics in Germany, Roland Haitz joined the Shockley Transistor Research Laboratory in Palo Alto, CA. For his work with Dr William Shockley, he received his PhD degree from the Technical University of Munich in 1963. After five years at the Physics Research Laboratory of Texas Instruments he joined Hewlett-Packard as R&D Manager for optoelectronics technology and component products. He supervised the development of numerous LED innovations, including the first LED numeric display, used in the HP-35 scientific calculator, and the first high-flux package for automotive signaling applications. During his time at HP/Agilent, the optoelectronics business grew from less than $1m in 1969 to more than $1.5bn at his retirement in 2002 as CTO of the Semiconductor Products Group at Agilent Technologies. Besides his career in business and technology management he also co-founded the Optoelectronics Industry Development Association (OIDA) and wrote the seminal paper that became the spark that ignited the solid-state lighting (SSL) revolution. Dr. Haitz is perhaps best known for his formulation of the concept that has become widely known as “Haitz’s Law”, which states that that every decade the cost per lumen for LEDs falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20.
Shuji Nakamura obtained B.E., M.S., and Ph.D. degrees in Electrical Engineering from the University of Tokushima, Japan in 1977, 1979, and 1994, respectively.
