Why is it that the housing temperature of an LED lamp with a power of only a few watts is very high?
As a new type of lighting product, LED bulbs have been favored by more and more people due to their advantages of high efficiency and energy saving, long life. However, some people may find that despite the power of only a few watts, the case temperature of LED bulbs is very high. Why is that?
First of all, we need to understand how LED bulbs work. LED refers to the phenomenon of light-emitting diodes, which emit light through the PN junction of semiconductor materials. Inside an LED bulb, an electric current passes through a semiconductor material, which excites an electronic transition, which produces light energy. Unlike traditional incandescent and fluorescent lamps, LED bulbs produce little to no heat.
