Basic knowledge of LED street lamp

Basic knowledge of LED street lamp

LED street lamps (LightEmittingDiode, light-emitting diodes) are semiconductor lighting lamps. It is a high-efficiency solid-state light source based on the formation of a semiconductor PN junction that can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, the holes injected into the P region and the electrons injected into the N region are diffused to the active region. After the radiation is combined to emit photons, the electrical energy is directly converted into light energy. It is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lights will become the best choice for energy-saving road lighting. Advantages: 1, LED
