The so-called LED is a semiconductor that can convert electrical energy into light energy. LED can be called a light-emitting diode. It is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. . The LED adopts electric field illumination, and the LED directly encapsulates the three primary color chips emitting red, green and blue wavelengths to form a multi-chip white LED, which is matched by an appropriate ratio according to the principle of spatial color mixing, so that three colors of light are matched. Mixed into white light, this LED lighting method is called three primary color LED direct color mixing method. LED technology is a breakthrough in lighting technology and an innovation. I believe that the future LED technology will be more advanced and more perfect. The so-called LED is a semiconductor that can convert electrical energy into light energy. LED can be called a light-emitting diode. It is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. . In the context of the energy crisis and the increasingly harsh global ecological environment, the form of saving and rational use of effective resources is unstoppable. All these forms of change have changed people's outlook on life and values. The energy shortage will curb the rapid economic development of a country. Electric energy is an indispensable thing in a country. Then, the amount of electricity spent on road lighting every year accounts for 20 to 30% of the global electricity consumption. Therefore, in order to alleviate power shortages and reduce energy consumption, it is necessary to promote The use of green light sources, high energy-saving, long-life, environmentally friendly LED lighting has gradually entered the field of vision. LED illuminators will use very little energy to achieve optimal lighting, which will greatly reduce the power required for road lighting. The replacement of street lamps in road lighting is also a large economic expense, and LED lighting has the advantage of long life. The current life of incandescent lamps on the market is about 1,000.
