30 w solar street lamps complete price

Material generally is die-casting aluminum LED street lamp holder, this kind of material of strong light, high hardness, at the same time of meet the demand for the quality of lamps and lanterns, maximum limit reduces the weight, let the lamps and lanterns is more safe and reliable, and aluminum in terms of its heat dissipation is also has a natural advantage, is

LED street lamp holder of materials for die casting aluminum, commonly solid, light and hard. It not only meet the requirement of the quality of lamps and lanterns, and maximum weight, make lamps and lanterns is more safe and reliable. In addition, the aluminum also has cooling natural advantages, is to make the best choice of the street lamp holder. As is known to all, LED street lamp, lamp holder is installed on the bracket, if the quality is too big, will bring the casing load, and cause potential safety hazard. Therefore, lamps and lanterns should be as light as possible, and shall ensure that sufficient hardness to meet the request of lamps and lanterns. In fact, industrial plastic and aluminum alloy can meet the requirements, but the coefficient of thermal conductivity of plastic far cannot satisfy the requirements, easy to aging in the outdoor wind and rain, thereby reducing the service life of lamps and lanterns. Therefore, aluminum alloy is the best choice. In addition, in terms of thermal conductivity, and it is second only to silver, copper and gold. Gold and silver is too expensive. The weight of copper is a problem. Aluminum is the best choice. Now many are aluminum radiator, this is the best material of lamps and lanterns. Aluminum alloy surface passivation layer, can prevent the external corrosion of aluminum alloy, suitable for outdoor use, greatly extend the service life of the lamps and lanterns.
