Loosely defined as LEDs with at least a 1-W capacity, high-power LEDs are a hot technology that’s very much in the market spotlight. Since their emergence, they have found themselves in a diverse ...

Fig 1. Single 1-W LEDs can serve as high-power, high-brightness devices. Fig 2. Certain LED applications fall into a gray area where low-power and high-power components both can fit the bill. However, ...

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 ...
