Introduction To LED Bulbs

An LED bulb is a lighting device that uses LEDs (light-emitting diodes) as its light source. Its shape mimics that of a traditional incandescent light bulb, hence the name "bulb lamp." Technically, an LED bulb works by using an electric current to excite electrons in the LED chip. When electrons recombine with holes, energy is released as photons, thus achieving the lighting effect. Compared to traditional incandescent and fluorescent lamps, this method of light emission has higher luminous efficacy and lower energy consumption. The luminous efficacy of LED bulbs typically reaches 80-120 lumens per watt, far exceeding the approximately 10 lumens per watt of incandescent bulbs and also surpassing the 50-70 lumens per watt of fluorescent lamps.
