"China Building Materials Network" First, the advantages of LED lighting fixtures are: First, LED as a point source, if the design is reasonable, can largely solve the problem of secondary light extraction and optical loss that traditional spherical light source must rely on light emission to solve Secondly, the uniformity of the LED illumination surface can be controlled. In theory, it can be completely uniform in the target area, which can also avoid the waste of light in the bright phenomenon under the traditional light source lamp. Third, the color temperature is optional. In the application of different occasions, it is also an important way to improve efficiency and reduce costs. Fourth, the technological progress of LED lighting fixtures is still very large. The advantages and disadvantages of LED street lighting, the disadvantages (the factors affecting the promotion and application of street lamps) are: LED lighting fixtures are currently too expensive, low luminous flux, the current price of LED lighting with the same illumination is about 4 times that of traditional light sources (but in In the street lamp products, the total cost of the light source part is not high, so the cost increase ratio in the engineering installation is not too high, and the application space is relatively large), which is unbearable in civilian use. The current design and manufacturing standards are confusing, and the damage ratio is high, which affects the life expectancy of LED lighting.
