Saving

Although LEDs do not generate UV or infrared light, only about 25 percent of the power they consume gets converted into visible light. The rest gets converted into heat, specifically at the positive/negative junction. Because regulating the heat at the junction is vital to maintaining LED efficiency and performance, many LED manufacturers incorporate a “heat sink” into the design that conducts heat away from the junction.
