LEDs 2011 Day 2 Highlights

Oct 28, 2011 On the second and concluding day of the LEDs 2011 conference and exhibition the attendees were presented with the several excellent case studies by representatives from Acuity Brands Lithonia Lighting, iO Lighting, Lighting Science Group and Excelitas Technologies. Tom Papanek, Director of R&D, LED Solutions,  at Excelitas Technologies, has uncovered many advantages of LED solutions for medical applications. He has emphasized the previously unaccessible possibilities of intelligent system control,  temperature control, shadow compensation and precise selection of lighting wavelength  that often are crucial for medical purposes.  He has also shown an impressively long list of additional tests required to validate LEDs  empowered solutions for medical use. Products designed by Excellitas are always performing well and exceeding test expectations.

The second half of the day was dedicated to the technological breakthroughs and attracted a lot of attention. David Horn, Chief Technology Officer from Switch Lighting has presented the unique novel design for the LED lightbulb to replace the standard incandescent. Switch75 lightbulb has solved several important problems such as efficient thermal management, achieved through liquid cooling, and excellent light distribution equalling almost 50% up and 50% down. That allows the user to conveniently replace standard 75W incandescent lightbulbs with 17W Switch75 lamp and enjoy the desired lighting quality benefits for at least 25,000 hours. Mr. Horn has noted the significant interest the company has received for their product that resulted sale orders already exceeding production capacity for this year.

Marshall Miles, Vice President of  Business Development from Inventronics has focused everyones attention on the development of reliable drivers for stable currents. Importance of the driver in overall performance of the LED lighting fixtures has been a constant topic of discussion throughout the conference.
The talk from Ralph Tuttle, Applications Engineering Manager at Cree Inc., has been greatly anticipated by the audience. He has  discussed  IES TM-21 Standard development  and implementation and emphasized the tremendous effort all the LED manufacturers have put into developing it. His talk has sparkled vivid after-talk discussions with LED lighting design engineers. LEDs Review had a possibility to receive an interview with Mr. Tuttle and it will be published separately.

Several presenters have brought up the topic or LED luminaries with remote phosphor design that allows to solve the problem of over time quality of light changes. Eran Fine, Co-CEO and President of OREE Inc. has not only discussed, but also presented the working innovative LED lighting cell and the prototype of  lighting fixture suitable for the office illumination that would weight only 1.3 kg. The patented novel design keeps the blue diodes embedded into the lighting guide that is connected to the thin layer of remote phosphor. This design allows for efficient thermal management, extreme light distribution efficiency and keeps phosphor cool and stable over the lifetime of the diodes.  Full details of this novel approach to planar LED Lighting fixture design will soon be published in the exclusive interview with Eran Fine.

Brian Chemel, Chief Technology Officer  from Digital Lumens, has demonstrated the power of contemporary intelligent Lighting fixtures that can not only smartly illuminate large industrial building, but also take any desired measurements and let you improve many parameters of the energy use and efficient resource management.

Presentation by Julian Carey, Director of Marketing at Intematix, had the full conference room despite of being the last after the intense seminar day. Intematix has introduced the novel ChromaLit remote phosphor solution for LED lighting applications earlier this year and it became an instant hit.  The fact that the phosphor composite can be separated from the blue LED energy source allows for exceptional shape, color and design freedom, it solves such LED attributed problems as unidirectional light, hot spots and inconsistency of light quality over time. Exclusive interview with Julian Carey will be published by LEDs Review in the due course.

The conference and exhibition has been an excellent meeting point for the Solid State Lighting professionals to discuss problems, find new collaborators and share good experiences. LEDs 2012 will certainly be the event to look forward to next year.
