An LED's junction-to-ambient temperature thermal resistance is a measure of its ability to dissipate heat from its junction-to-ambient air, which is a function of its chip size and package. In terms ...

Power saving is one of the key selling points associated with LED technology. Compared to conventional light bulbs, LEDs provide a significant reduction in the power consumption of lighting and an ...

Unlike incandescent tungsten-filament light bulbs, high-power LEDs do not radiate heat. Instead, LEDs conduct heat from their PN junction to the thermal slug on the LED package. Because the heat ...

Two new LED controllers—the LDS9001 and LDS9003—feature a patent pending LED-Sense temperature-compensation engine. This innovative feature allows for direct in-situ monitoring of the LED junction ...

In Part 1 of this report, featured in the October 2010 issue, we explored the emergence of the solid-state lighting (SSL) revolution. We also covered the basics of light-emitting diode (LED) chips and ...
