a: LED aluminum plate is a printed circuit board, which is the meaning of printed circuit boards. It is an important part of the solar led street lamp light source. Circuit board material is aluminum alloy. It use the aluminum plate instead of the commonly used glass fiber board, the price is low, to better solve the cooling problem in the working process of the light emitting diode chip. Solar led street light used in the aluminum plate is usually by the circuit layer ( Copper foil layer) , thermal insulation and metal base consisting of a single panel ( Currently do not use other led lights, such as double panel and multilayer panel) 。 Circuit layers are used to implement the led assembly and connection, need big current carrying capacity. Commonly used thickness for 35 microns to 280 microns of copper foil. Heat insulation layer is the core of the led aluminum plate, mainly have the effect of adhesive, insulation and thermal conductivity. It generally by special signal lamp polymer filling of special ceramics in Inner Mongolia, good thermal conductivity, heat aging and requirement of mechanical bearing capacity. Aluminum plate is aluminum plate support components, which make use of its good thermal conductivity, electrical insulation and processing performance. Ordinary aluminum plate aluminum plate thickness of 0. 8, 1. 0 and 1. 2, 1. 5, 2. 0, 2. 5 and 3. 0 mm
