Buying LED Bulbs? Good. But Here Are 5 Things to Think About First

High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light (about 70% heat and 30% light). If this heat is not removed, the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable. Thus, thermal management of high power LEDs is a crucial are… NettetHow do led light fixtures to reduce heat? Under normal conditions, there are three ways of heat transfer: conduction, convection, and radiation. Conduction means that the heat between objects in direct contact is transferred from the one with a higher temperature to the one with a lower temperature.
