LED street light is closely related to people's production and life. With the acceleration of my country's urbanization process, the development of solar power generation in the field of street lighting has become increasingly perfect. So what are the key points for purchasing LED street lights? Let's go take a look next.
This is the content list:
The luminous efficiency of LED street light
The light decay of LED street light
The self-weight problem of LED street light
Heat dissipation of LED street light
As LED street light technology becomes more and more mature, high-power LED street light sources can already meet the needs of general street lights. The luminous efficiency of the general LED street light is 100LM/W, and the commonly used high-power LED street light is 50-60LM/W. Using foreign LED chips can reach 80LM/W. The higher the luminous efficiency of LED street lights, the better the energy-saving effect. This is also one of the most important indicators for choosing LED street lights. But the LED standard does not stipulate this, so be sure to check carefully when buying LED street lights.
To reduce the cost of LED street lights, some businesses have used hundreds of 0.5W low-power LEDs. However, the light decay of this low-power LED street light is very serious, and the lifespan of the light decay to 80% is only 1000 hours. Therefore, like LED street lights that need to be used for a long time, such low-power LED street lights are not allowed. If you choose high-power LED street lights, the degradation of LED street lights will be much better.
Because of the high technical content of LED street lights and the complex composition of LED street lights, the requirements for corresponding supporting materials for LED street lights are higher. However, some LED street light manufacturers have tried their best to reduce the weight of LED lamp holders. From the original LED street light with a single lamp holder of about 30 kg to more than 10 kg, the weight of the LED street light has a further downward trend.
Because LED is a semiconductor component when its chip is affected by temperature and reduces to 30% of the initial luminous flux, it will lose its illumination meaning, that is, the end of life. In theory, the life of a high-power LED street light is 30,000 to 50,000 hours. But its important prerequisite is that the LED street light has good heat dissipation.
