efficiency, constant brightness and brilliant colour rendering, irrespective of which technology is used to create white light,” is how Matthias Winter sums it up.
Technical data:
a critical role in enabling both high efficacy and excellent colour quality in solid state lighting. In only two years Pacific Light Technologies has become a trendsetter in the use of quantum dot down-converters, so I’m excited to help guide them to success,” says Walker.
He adds, “With PLT’s unique low self-absorption design, multi quantum dot mixtures can provide custom tailored light spectra - ‘colour where you want it’ - that can achieve the black-body performance of incandescent and halogen bulbs without comprising efficacy. And better yet, their quantum dots are very robust and operate in industry standard silicone materials.”
“We are delighted to have Bob join us so that we can benefit from his expertise and industry knowledge,” comments Ron Nelson, CEO of PLT. “His advice in the early days of PLT helped us build our industry leading team and brand. He is a great addition to our board.”
Osram says thanks to its excellent efficiency, the MicroSideled is the ideal energy saver for portable devices.
Bridgelux ex-CEO to brighten Pacific Light Technologies
The LED innovator in quantum dot down-converters for solid state lighting and displays has taken on a new board member
Pacific Light Technologies (PLT), has appointed Robert Walker to its Board of Directors.
This is to aid the transition of the company from a development stage to the commercial phase of its growth.
Robert Walker, a veteran of the solid-state lighting industry, brings a deep level of experience and understanding in the markets and applications of LEDs.
Walker is currently CEO of an early-stage start-up, and from 2005 to 2007 was CEO of high-power LED lighting company Bridgelux. He also held key roles at Sierra Ventures, Vincera Ventures, and Emcore, and is a principal of YEBY Associates consultancy.
This experience makes him an authority in the field of high-brightness LEDs since the industry’s inception. In particular Walker has extensive first-hand knowledge of the Asian LED industry where much of the world’s production is located.

Aixtron`s GaN-on-Si tool wins Aurora 2013 award
After being awarded at the CS awards for this tool the firm has been once again been recognised for its cost efficient MOCVD AIX G5+ reactor used for gallium nitride-on-silicon development
Aixtron SE was awarded the 2013 LEDinside Aurora Award in the category “Most efficient MOCVD Equipment” on June 11th, 2013.
Aixtron received the award for its AIX G5+ technology for Gallium-Nitride-on-Silicon (GaN-on-Si).
Aixtron’s system was chosen due to its production efficiency and technological advancement and was already awarded with the CS Industry Award in March of this year.
Aix-834-5x8” reactor
“Producing gallium nitride based LEDs on 200 mm silicon substrates is a promising route towards a much lower chip manufacturing cost,” comments Andreas Tönnis,
