The volume of the substrate is limited to a considerable extent in consideration of various conditions such as cost, use conditions, ease of assembly, and load. Unable to expand outward without restriction, and it only sets heat dissipation fins on the plane of the substrate, the overall heat dissipation surface area formed is quite scarce, and cannot meet the heat dissipation requirements of various high-power LEDs; it really needs to be improved .

Utility model content

In view of this, the purpose of the present utility model is to provide a heat dissipation structure of an LED lamp with better heat dissipation effect.
