Abstract: Due to green lighting, China is the most widely used country in the world, which is the reason for using fluorescent lights. However, as people pay more and more attention to health and environmental protection, the harm caused by fluorescent lamps has also been criticized more and more.

　　 Four, mercury lamp

1. Working principle: Mercury discharge is used to generate mercury vapor to obtain a visible light source. Mercury lamps can be divided into low pressure mercury lamps, high pressure mercury lamps and ultra high pressure mercury lamps.

2. Advantages: simple structure, low cost and low maintenance cost.

How to make led outdoor solar garden light signs

First, apply at the local online public resource trading center. The manufacturer of led outdoor solar garden light is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, and long life. Therefore, led outdoor solar garden light will become a good choice for road lighting energy-saving transformation. led outdoor solar garden light It is a kind of high-efficiency solid-state light source based on semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse to the active area, they recombine by radiation to emit photons, which directly convert electrical energy into light energy. After completing the online information, review the original company
