What material is suitable for LED street lamp head


The material of the LED street lamp head is generally die-cast aluminum. This material is strong, light, and hard. While meeting the quality requirements of the lamp, it minimizes the weight and makes the lamp safer and more reliable. In addition, aluminum is also natural in terms of heat dissipation. The advantage is a good choice for making street lamp heads.

LED street lamp

Everyone knows that the LED street lamp head is installed on the bracket. If the quality is too large, it will cause a large load on the socket and cause hidden safety hazards. Therefore, the lamp should be as light as possible while ensuring sufficient hardness to meet the requirements. The requirements for the protection of lamps, in fact, industrial plastics and aluminum alloys can meet the requirements, but plastics are far from meeting the requirements in terms of thermal conductivity, and they are easy to age in the wind and rain, reducing the life of the lamps. Therefore, aluminum alloys Is the best choice. In addition, it is second only to silver, copper, and gold in terms of thermal conductivity. Gold and silver are too expensive. Copper weight is a problem. Aluminum is the best choice. Many radiators are now made of aluminum, which is best for heat dissipation of lamps. There is a passivation layer on the surface of the aluminum alloy, which can prevent the outside from corroding the aluminum alloy, so it is suitable for outdoor use, which greatly increases the service life of the lamp.
