SWITCH Lighting’s™ SWITCH bulbs have a ring of metal prongs, each with a computer chip on it to emit light, which is immersed in liquid that fills each bulb. The liquid cools the chips while acting as a lens to magnify light. SWITCH bulbs use 80 percent less electricity than incandescent bulbs and last for about 25,000 hours no matter often you switch them on or off. Learn … [Read more...]
Lighting-Class LEDs Deliver Twice the Lumens-Per-Dollar
Cree, Inc.’s new XLamp® XB-D LED delivers twice the lumens-per-dollar of other LEDs, in a small lighting-class footprint of 2.45 mm x 2.45 mm. The XB-D LED is 48 percent smaller than the XLamp XP package and ideal for lighting applications where high lumen density and compact light sources are required. The XB-D LED uses up to three times fewer LEDs, three times fewer optics … [Read more...]
Organic LED Lighting in European Dimensions
Led by Philips Technologie GmbH in Germany, the OLED100.eu team has been working on OLEDs for the last three years. The aims and objectives of the study were to boost the luminous efficacy, strengthen the lifetime, upscale the light-emitting area, optimize processes to slash production costs, and standardize measurement based on application research. The OLED100.eu team … [Read more...]
LED Design Case Study: Down Lighter Thermal Management with Simulation
Future Facilities released a case study showing that its new CFD software for electronics cooling design, 6SigmaET solves the problem of how to shrink electronics devices that generate heat. The Future Facilities' case study describes how Advanced Thermal Solutions-Europe, BV used Future Facilities' 6SigmaET software to model lamp performance while simultaneously reducing heat … [Read more...]
Thermal Modeling and Testing for LEDs and Luminaires
Mentor Graphics Corp. has introduced the T3Ster (“trister”) thermal transient tester for LEDs, board-level LED arrays and luminaires. Together with the company’s FloTHERM thermal simulation tool based on computational flow dynamics (CFD), lighting designers can model and improve heat transfer through the LED, printed circuit board (PCB) or luminaire system during design and … [Read more...]
