The LED Street Light PCB consists of a circuit layer, a thermally conductive insulating layer and a metal base layer. The circuit layer (copper foil) is usually etched to form a printed circuit, so that the various components of the assembly are connected to each other. In general, the circuit layer is required to have a large current carrying capacity, so that a thick copper foil should be used, and the thickness is generally 35um-280um.
The thermal conductive insulation layer is the core technology of PCB aluminum substrate. It is generally composed of special polymer filled with special ceramics. It has small thermal resistance, excellent viscoelasticity, heat aging resistance, and can withstand mechanical and thermal stress.
The metal base layer is a supporting member of the aluminum substrate, and is required to have high thermal conductivity, generally aluminum plate, or copper plate (in which the copper plate can provide better thermal conductivity), and is suitable for conventional machining such as drilling, punching and cutting.

Advantages and Application
PCB materials have advantages that are unmatched by other materials. It is suitable for surface mount SMT process of power components. It does not need a heat sink, the volume is greatly reduced, the heat dissipation effect is excellent, and it has good insulation performance and mechanical properties.
It is used in the street light ,high way led lamp,tunnel lamp ,square lamp,road lamp, city lighting, parking spot lamp, scenery area and so on. It will be the best to replace traditional high pressure street light .It is also the best choice to retrofit the old HPS lamps as replacement.
