LED street lamp is always made of die cast aluminum, this material is sturdy and lightweight, high hardness, light on the quality to meet the demand at the same time, greatly reduce the weight, make the lamp more safe and reliable, in addition to aluminum also is a natural advantage in the heat, is used to make the choice of road lamp.

As we all know, LED street lamp is installed on the bracket, if the quality is too high it will be great for a load, cause safety hazards, so lighting should be as lightweight as possible. At the same time to ensure sufficient hardness, meet the requirements of the actual lighting protection, industrial plastic and Aluminum Alloy are can meet the requirements, but not in the plastic thermal conductivity on demand, also easy to aging outdoors to reduce the life of lamps, exposed to wind and rain, so Aluminum Alloy is a good choice. In addition, in the thermal conductivity, second only to silver, copper, gold, gold and silver are too expensive, copper weight is a problem, aluminum is on the election, and now a lot of radiators are aluminum, lamps used for heat dissipation is better. The surface of the aluminum alloy has a passivation layer, which can prevent the corrosion of aluminum alloy from outside, so it is suitable for use in outdoor environment, and greatly increase the service life of lamps and lanterns.

Because aluminum alloy has many advantages, even if the expensive point, still can choose as the material of the road lamp holder.
