Noise-optimized heat dissipation

Round fan cools LEDs. Despite their high light output per watt, LEDs still convert around 80 percent of the power they consume into heat, which must be dissipated by cooling.

LED lamps consist of a light source, or rather one or more LEDs, a cooling body and an electronic control circuit. However, because LEDs still convert around 80 percent of the power they consume into heat, which, unlike incandescent lamps, is not radiated, this heat must be dissipated by cooling. In order for the advantages of LEDs, such as long service life, high reliability, small dimensions and high light output per watt, to take effect, the chip temperature must not exceed the limit specified by the manufacturer (usually 125°C) even in the most unfavorable operating case …
