Sapphire led

LED radiator starts from two aspects: material and structure. At present, the commonly used material is wrought aluminum alloy. Although the thermal conductivity of copper and silver is higher than that of aluminum, silver is more expensive and the proportion of copper is larger. For the same weight of copper and aluminum, aluminum has better heat dissipation. The second is the structural problem. At present, honeycomb heat dissipation is widely used. Or use the whole lampshade as a radiator. There are many such patents, I suggest you have a look.
