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...]
Thermally Conductive Compounds for Enhanced LED Luminaires
Global custom engineered thermoplastics compounder RTP Company has introduced a line of thermally conductive compounds for replacing metal heat sinks and housings in light-emitting diode (LED) luminaires. The new compounds have been specially formulated to increase the thermal management design options available for LED lighting as it expands into a broader range of end-use … [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...]
Diamond-Thin Films Cool Electronics
Two new studies performed at the U.S. Department of Energy’s Argonne National Laboratory have revealed a new pathway for materials scientists to use previously unexplored properties of nanocrystalline-diamond thin films. The unusually attractive thermal properties of diamond thin films have led scientists to suggest using this material as a heat sink that could be integrated … [Read more...]
