50w Street Light Housing Wholesaler introduces the cooling technology of LED street lamp heads. Generally, a hot plate is used. It is a 5mm thick copper plate. In fact, it is a uniform temperature plate and the heat is constant. A radiator is also installed to heat the lamp, but the weight is too large. The weight of the street lamp system is very important. Generally, the height of the street lamp is six meters. Especially in typhoons, earthquakes will increase the risk and accidents may occur. Domestic manufacturers adopt the world's first pin-shaped heat dissipation technology. The heat dissipation efficiency of the pin-shaped radiator is greatly improved compared with the traditional fin-type radiator. The junction temperature of the LED can be lower than ordinary radiator by more than 15℃, and the waterproof performance is better than ordinary aluminum alloy radiator. , And weight and volume have also improved.
Mainly: natural convection heat, forced cooling by installing fans. The installation of a fan forced cooling system is complicated, low reliability, and high cost of heat pipe loop heat pipe cooling. For street lights used outdoors at night, the cooling surface is located on the side, and the smaller size is conducive to the air advantage of natural convection. Therefore, it is recommended to choose natural convection cooling as much as possible for LED street lights.
The cooling fin area is arbitrarily set, the arrangement of the heat sink is unreasonable, the arrangement of the cooling fin does not consider the use of the lamp, which affects the role of the fin, emphasizes the heat conduction link, and ignores the convection cooling. Although many manufacturers consider various measures, they are not aware The amount of heat ultimately depends on the appearance of the light-emitting area of the lamp. Ignoring the balance of heat transfer, if the temperature distribution of the fin A is severely uneven, a part of the fin will not work or the effect will be limited.
Through the above introduction, Energy Saving Street Light Housing Company hopes that you can simply refer to the content of this article in future use.
