TopTen USA, a source of news on sustainable products, has ranked the PAR30 and PAR38 TCP LED light bulbs as the most efficient and highest quality consumer option on the market. The TCP LED PAR38 bulb was ranked #1 out of 67 entries and the TCP LED PAR30 bulb was ranked #1 out of 49 entries. Judging was based on important factors such as energy savings, economics (lifetime cost … [Read more...]
Cooling LEDs with Air Instead of Heat Sinks
Zeta LED has developed an air-cooled LED light bulb. The Lifebulb consumes 10 watts of power and puts out as much light as a standard 60 watt incandescent, pretty much like existing LED bulbs. The difference comes in the absence of an aluminum heat sink. Zeta keeps its bulb cool by channeling air through the vents in the structure itself: the vents are the strips and holes … [Read more...]
Heat Sink for Packing Densities up to 100W/cm2
Ceramtec’s CeramCool Box is made for homogeneous and efficient cooling of packing densities up to 100W/cm2. For example, with an edge length of just 16 x 40 x 40 mm it has a total cooling capacity of 1600W, which corresponds to a thermal capacity of 1200W. The maximum temperature of an LED is just 90°C with a coolant flow rate of 180l/h and an ambient and cooling water … [Read more...]
New Liquid-Cooled LED as Bright as 100W Bulb
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...]
