10 Years Warranty 80w Led street light solar
LED is a semiconductor component, and its wafer is affected by temperature and reduced to 30% of the initial luminous flux, it will lose the meaning of illumination, that is, the end of life, theoretically, the life of high-power LED street lamp is 30,000-50,000 hours, but The important premise is that it has good heat dissipation. It is worth mentioning that the domestic manufacturers have adopted the world's leading needle cooling technology.
Suppose a city has three sections with a length of 3 km, 5 km, and 10 km. The street lamps are laid every 30 meters, and the total number of street lamps required for each of the three sections is 202pcs, 334pcs. 668pcs, the traditional street lamp is based on a high-pressure sodium lamp with a power of 250W, and the LED street lamp is compared with a power of 50W.
The traditional street lamp has a unit price of 1,000 yuan/inch, and the LED street lamp has a unit price of 3000/inch. The cost of the light source for the three lengths of traditional street lamps is 202*1000=202,000 yuan, 334*1000=334,000 yuan, 668. *1000=66.8 million yuan, the cost of light source for laying three kinds of roads with LED street lights are: 202*3000=606,000 yuan, 334*3000=100.2 million yuan, 668*3000=20.04 million yuan.
