High-efficiency heat dissipation device for LED projection lamp

Abstract

The application provides a high-efficiency heat dissipation device of an LED spotlight, and belongs to the technical field of spotlights. The high-efficiency heat dissipation device of the LED spotlight comprises a casing, an LED lamp plate module and a matched power supply module are arranged in the casing, a rectangular through ventilation hole is horizontally arranged at the center of the casing, the lamp plate module and the power supply module are arranged on the two sides of the ventilation hole respectively, a blowing mechanism is arranged in the casing and blows air obliquely towards the ventilation hole, and a heat dissipation block is movably inserted into the ventilation hole. The application has the following effects: the arrangement of the heat dissipation block greatly increases the heat dissipation area and ensures the structural strength of the position of the ventilation hole; the blowing mechanism is arranged in the casing, air is blown obliquely towards the ventilation hole, more air flow is caused to pass through the ventilation hole and the heat dissipation block, and high-efficiency air cooling heat dissipation is realized; and space is fully utilized, and the structure is more compact.
