Water-cooled LED street lamp

Abstract

The invention relates to an LED street lamp, in particular to a water-cooled LED street lamp, comprising a transparent cover that penetrates up and down and is closed around, a shading cap fixed on the top of the transparent cover, a cylindrical radiator located at the bottom of the transparent cover, and located in the inner cavity of the transparent cover. The high-power LED lamp body in the middle; wherein: the outer wall of the bottom of the heat sink is provided with a mounting seat, and the mounting seat is provided with a mounting hole A; the center of the heat sink is provided with a mounting hole B, and in the mounting hole A water injection chamber is arranged on the wall between B and the outer wall of the heat sink; an end cover matching the heat sink is fixed on the upper end surface of the heat sink; a water inlet pipe communicating with the water injection chamber is fixed on the lower end face of the heat sink Outlet pipe; the bottom of the transparent cover is fixed on the upper end surface of the end cover. The advantages of the present invention due to the structure are: fast assembly, reduced volume of the radiator, prolonged service life and reduced use cost.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to a water-cooled LED street lamp with reduced volume, quick assembly, prolonged service life and reduced use cost. Background technique [0002] In the existing residential quarters, there are generally public green belts, and in the public green belt area, there are generally community garden corridors for the owners to take a leisurely walk. In order to ensure the safety of the owners walking at night, they are generally installed There are lights. The lighting lamps used in the prior art are generally high-power LED street lamps, and such high-power LED street lamps generally include a closed housing, an LED lamp body located in the housing, and a radiator located below the LED lamp body. In order to ensure heat dissipation efficiency, the structure of the radiator is complex and bulky, which makes it poorly coordinated with the garden when installed in the garden corridor of the residenti...

AI Technical Summary

Problems solved by technology

In order to ensure heat dissipation efficiency, the structure of the radiator is complex and bulky, which makes it poorly coordinated with the garden when installed in the garden corridor of the residential area. In some areas where the temperature is relatively high in summer, the radiator itself absorbs the heat of the sun relatively quickly. When the light is turned on at night, the heat absorbed by the heat sink during the day has not been transmitted to the ground in time, which can easily cause heat damage to the LED lamp body, resulting in a short service life of the LED lamp body and high use costs
