Technical specifications for high-power LED street lights - Air convection heat dissipation type high-power LED street light fixtures

High power LED street light fixtures with air convection and heat dissipation. The purpose is to solve the heat dissipation problem of high-power LED lamps and propose an air convection heat dissipation type high-power LED street lamp lamp, which includes a lamp head component, a lamp heat dissipation body component, and a lamp tail component. The lamp heat dissipation body component is an arc-shaped cylindrical shell, with openings at both ends. The two sides of the arc-shaped cylindrical surface are facades, and the facade also has array through holes, In the inner cavity of the arc-shaped cylindrical shell, there are 4-10 axially arranged vertical heat conducting plates fixedly connected to the arc-shaped cylindrical surface and the arc-shaped cylindrical surface. The vertical heat conducting plate and the two facades on both sides of the arc-shaped cylindrical shell are also provided with array through holes. The vertical heat conducting plate and the two facades on both sides of the arc-shaped cylindrical shell form 5-11 heat dissipation channels for hot air flow in the lamp heat dissipation component. The advantage of this utility model is that there are multiple heat dissipation channels for hot air flow in the inner cavity of the heat dissipation body, and the vertical heat conduction plate also serves as the heat dissipation surface, increasing the heat exchange surface and high heat discharge efficiency.
