In the past few years, landscape lamp manufacturers have used thermal conductive materials, which are generally thermal conductive silicone grease. The cost of thermal conductive silicone grease is relatively economical and applicable. But it needs to be applied on the heat dissipation surface in an all-round way. The main problem is that the thickness of the coating is not uniform. The contact between heat dissipation copper cladding plate and radiator metal bracket lamp or metal shell is the main problem. Now many LED lamp manufacturers are using the softness. Silicone thermal conductive sheet can be used for large area matting and easy operation. It can effectively transfer heat to heat dissipation devices.
