High-power LED street lamp

Abstract

The invention relates to a high-power LED street lamp. One end of a lamp housing (1) is fixedly connected with an electrical store (2), and the lamp housing (1) is a W-shaped slot. Two slopes in the shapes like a reversed V are symmetrically arranged on the center of the lamp housing (1), one LED reflector cup (3) is arranged on each of the two slopes, and the rear of the lamp housing (1) is provided with cooling fins (1c). With the advantages of simple structure, unique design and easy installation, the high-power LED street lamp is characterized in that the LED reflector cups have uniform light distribution performance and are arranged on both sides of the lamp housing so that light of the street lamp does not have light spots and dead zones; and meanwhile, due to the direct contact of an LED light board and the lamp housing and the arrangement of the cooling fins, the heat dispersion performance is highly improved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a high-power LED street lamp. Background technique [0002] At present, traditional street lamps generally use incandescent lamps or ordinary energy-saving lamps. The service life of incandescent lamps is about 1,000 hours, and the service life of ordinary energy-saving lamps is generally about 3,000 hours. The service life is relatively short, and lamps need to be replaced frequently. Therefore, it is very troublesome to replace, and often the power is relatively large, which consumes a lot of electricity. As a new type of light emitter, LED has the characteristics of high light efficiency, energy saving, impact resistance and vibration resistance. Especially in the context of advocating energy saving and environmental protection, it is widely used, but it is found that a large number of high-power LED street lights have the following two main defects in use: At present, most of the LED light sou...

Problems solved by technology

Especially in the context of advocating energy saving and environmental protection, it is widely used, but it is found that a large number of high-power LED street lights have the following two main defects in use: At present, most of the LED light source boards in high-power LED street lights are not directly connected to the heat dissipation shell. Contact, there are adhesives, partitions, etc. in the middle, which lead to poor heat transfer effect, and the heat dissipation effect of the LED light source board is not good, because the LED will generate heat when it is working, especially the power of street lamps is relatively large, and the temperature of the LED light source board will increase over time. It will continue to rise, and the life of the LED will be greatly shortened if the temperature is too high; second, the light emission of the LED is different from that of ordinary lamps (the general lamps emit light at 360°, and the LED emits light at 180°), and the current high-power All LED street lights appear, there are light spots on the irradiated, and the irradiated light is very uneven.
