Application prospect analysis of LED lighting in road lighting1

The so-called LED is a semiconductor that can convert electric energy into light energy. LED can be called light emitting diode, which is a solid semiconductor device that can convert electric energy into visible light. it can directly convert electricity into light. The LED uses an electric field to emit light, and the LED directly encapsulates the three primary color chips emitting red, green and blue wavelength together to form a multi-chip White LED. Through the principle of spatial color mixing, according to the appropriate proportion of matching, so that the three colors of light mixed into white light, this LED light emitting method is called three primary color LED direct color mixing method. LED technology is a breakthrough and innovation in lighting technology. I believe that LED technology will be more advanced and perfect in the future. The so-called LED is a semiconductor that can convert electric energy into light energy. LED can be called light emitting diode, which is a solid semiconductor device that can convert electric energy into visible light. it can directly convert electricity into light. In the case of energy crisis and increasingly harsh ecological environment, the form of saving and rational use of effective resources is unstoppable. All these forms of changes have changed people's outlook on life and values. The problem of energy shortage will curb a country's rapid economic development. Electricity is an indispensable thing for a country, and then the electricity spent on road lighting accounts for 20% of the lighting power consumption every year. 30. Therefore, in order to relieve the shortage of electricity and reduce energy consumption, it is necessary to promote the use of green light sources. LED lights with high energy saving, long service life and favorable environmental protection have gradually entered people's vision. LED lighting lamps will use very little energy to achieve good lighting effect, which will greatly save the electric energy needed for road lighting. The replacement of street lamps after damage in road lighting is also a large amount of economic expenditure, and LED lamps have the advantage of long service life. The life of incandescent lamps currently on the market is about 1000.
