LED lamp heat dissipation structure

Abstract

The utility model discloses an LED lamp heat dissipation structure, and belongs to the technical field of LED street lamps. Comprising a fixing frame, an LED lamp is arranged at the bottom of an inner cavity of the fixing frame, a heat dissipation assembly is arranged at the top of the LED lamp, multiple installation assemblies are arranged at the bottoms of the two side walls of the inner cavity of the fixing frame, and connecting bases are arranged on the side walls of the fixing frame. The LED lamp heat dissipation structure is installed at the needed position through the connecting base, air between the LED lamp and the heat dissipation substrate is conveniently exhausted through the heat conduction pad, contact is more sufficient, heat exchange is conducted through the heat dissipation substrate and the heat dissipation fins, natural wind blown in through the ventilation holes enables the heat dissipation substrate and the heat dissipation fins to be cooled, and the heat dissipation effect is better. Collected rainwater flows into the water conveying pipe through the water inlet, so that the cooling speed of the heat dissipation fins is increased, the heat dissipation effect of the LED lamp is effectively improved, and the LED lamp is easier and more convenient to disassemble through the mounting assembly. According to the structural design, the cooling speed of the cooling fins can be increased conveniently, the heat dissipation effect is good, and the LED lamp can be disassembled and assembled conveniently for maintenance or replacement.
