Abstract

The invention discloses a water-cooled radiating light emitting diode (LED) street lamp, which comprises a lampshade, an LED chip, a radiating pedestal, a stand pipe, radiating water pipes, a submersible pump, a water tank and a radiating shell, wherein the LED chip is tightly attached to the radiating pedestal, the radiating pedestal is hollow, the central open pore of the radiating pedestal is connected with the stand pipe, and four sides of the radiating pedestal are connected with the water tank through the radiating water pipes; the water tank is fixedly connected with the inner wall of the radiating shell; the submersible pump is arranged in the water tank; and the drainage port of the submersible pump is connected with the stand pipe. The LED street lamp has the advantages that: by water-cooled radiating, over-high temperature rise of the LED chip is prevented, the LED chip is difficult to damage due to high temperature, and the service life of the lamp is prolonged; and the lamp is easy to manufacture, install, produce and operate.

Description

technical field

[0001] The invention relates to an LED street lamp, in particular to a water-cooled and heat-dissipating LED street lamp. Background technique

[0002] Existing LED street lamps, because they generate a lot of heat during work, will cause thermal shock to them. If the heat is not dissipated to the outside in time, the temperature of the LED chip will rise, and the chip will often fail when working at high temperature. In order to increase the reliability of the work, a radiator should be designed to dissipate heat from the chip. Existing radiators for LED street lamps generally use the surface of the lamp shell to dissipate heat in order to improve the heat dissipation effect. However, there is air between the heat dissipation substrate of the LED chip and the lamp shell to isolate heat transfer, and the heat dissipation effect will be greatly reduced, resulting in the use of LED street lamps. Decreased lifespan, or even burnt out. Contents of the inventio...
