CSEM announces EU-funded LASSIE-FP7 large-area SSL module project
Switzerland based R&D lab will lead collaborative research charged with developing SSL modules that combine the reliability and performance of LEDs with tunable organic elements in planar modules for use in luminaires such as architectural recessed troffers.
GaN on silicon: A breakthrough technology for LED lighting (MAGAZINE)
Over the last decade, progress in light-emitting diode performance has been nothing less than phenomenal. LEDs today are performing at 50% wall plug efficiency, meaning that 50% of the applied power is emitted as light.
LEDs chart a new path for tunnel lighting (MAGAZINE)
LEDs are proving their benefits in most outdoor area lighting applications, but the point sources integrated in solid-state lighting fixtures are an especially good match for tunnel applications. Dale Kane explores specific challenges posed by tunnels and how to...
Understand the true cost of LED choices in SSL systems (MAGAZINE)
The LED component cost is only one facet of the design and production cost for solid-state lighting (SSL) systems. Other factors that impact the overall cost, performance, and lifetime of general lighting products include the suitability of components for the intended...
Osram adds LEDs for auto rear lighting, moves color production to 6-in line
Osram has expanded its Oslon Black Flat LED line to include colored LEDs designed for auto exterior applications including tail lights, turn indicators, and brake lights, while the company also said that it is first in the industry to move red, orange, and yellow LED...
Refocus design challenges to move LED lighting forward (MAGAZINE)
Brad Koerner, director of experience design at Philips Lighting, asks if R&D into sustainable materials and fabrication techniques could lead to radical cost reductions in the LED-based lighting industry.
LEDs Magazine top 20 stories of 2013: Readers keep A-lamps ranking highly
While SSL experts regularly project the demise of the lightbulb form, the popularity of stories focused on LED-based lamps with our readers make it clear that today it remains a very hot topic, outpacing even packaged LED stories.
Quantum dot technology progresses, ships in LED-backlit LCD TVs (MAGAZINE)
Ken Marrin reports that quantum dots are poised to unleash high-color-gamut performance in LCDs, especially in TV applications, as materials manufacturers work through reliability, cost, and lifetime issues.
IES TPC considers LM standard for remote phosphor optics (MAGAZINE)
Remote-phosphor technology offers potential advantages to SSL such as better color uniformity and maintenance, and, as Jianzhong Jiao explains, may soon have the benefit of an IES testing standard such as the LM-80 standard defines for LEDs.
Reflectors and lenses vie for usage in SSL systems (MAGAZINE)
LED point sources have fundamentally changed the optics industry, reports Marc Hübner, and developers working on SSL systems must consider both reflectors and lenses and match designs to the application at hand.
