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 ...

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 ...

As their production costs fall, LEDs are being used more often in applications ranging from handheld devices to automotive and architectural lighting. Their high reliability (operational lifetimes of ...
