LED road lamp

Abstract

The invention is an LED streetlight, which comprises a radiator module and a completely sealed power supply. The radiator module comprises main module components such as a circuit board, LED lighting crystal grains and a radiation finned seat. With the help of the heat-dissipation finned seat as an outer cover for the streetlight, streetlight and the atmosphere space can in direct contact for radiating, and the heat temperature produced by the LED crystal grains and the circuit board can be directly transmited to a vertical tube so as to achieve double radiation effect. The heat source of the power supply is radiated on the vertical tube through a sealed casing of the power supply, thereby greatly increasing theradiation area, reducing the temperature, improving radiation efficiency, and preventing the power supply from being influenced by the outdoor environment and climates so as to prolong the service life of the LED circuit board, the LED lighting crystal grains and the power supply. The circuit board can be quickly assembled and disassembled on a radiation base, thereby increasing the convenience of assembling and disassembling the circuit board.

Description

technical field [0001] The present invention relates to an LED street lamp, in particular to a street lamp that utilizes a heat dissipation fin seat as the outer cover of the street lamp to be directly exposed to the atmospheric space and directly contacted with the atmospheric space, so as to achieve better heat dissipation effect, and the LED light-emitting crystal LED street lights with long service life and durability. Background technique [0002] According to the existing LED light-emitting street lamp, the typical structure is such as the assembly structure of the LED street lamp and the heat dissipation module of the Taiwan New Certificate No. M303333. The space is limited and cannot be in contact with the air space, and the heat is concentrated inside the upper cover, so that the purpose of rapid heat dissipation cannot be achieved. In addition, the heat pipe is vertically connected between the partition plate and the heat conduction sheet, and only a short positio...

AI Technical Summary

Problems solved by technology

[0002]According to the existing LED light-emitting street lamps, the typical structure is such as the assembly structure of LED street lamps and heat dissipation modules with Taiwan New Certificate No. M303333. The above-mentioned scheme must pass through a cover plate) to cover the heat conduction sheet. In this way, the heat dissipation space of the heat conduction sheet is limited and cannot be in contact with the air space.

In addition, the heat pipe is vertically connected between the partition plate and the heat conduction sheet, and only a short position of the heat pipe is used as the heating end, and only the heating end is in contact with the surface of the vapor chamber. The length is short, the heating area, and the volume are small, so the temperature from the heat conduction temperature of the heat conduction tube to the heat conduction sheet is limited, and it is impossible to achieve the purpose of high-efficiency heat dissipation in a short period of time, so the service life of the LED lamp group cannot be effectively improved.
