Problems solved by technology

Most of the existing heat dissipation technologies for LED street lamps use a flat structure directly pasted on the back of the heat dissipation substrate. This method is simple and practical, but in fact the area of ​​the heat dissipation substrate is usually not enough to ensure that the lamps have sufficient heat dissipation effect
Moreover, the horizontal cooling fins are not conducive to the formation of natural convection, and there is a risk of dust accumulation and failure during long-term use

Embodiment

[0029] Such as Figure 1 to Figure 6 As shown, a body-type gravity heat pipe LED heat dissipation system includes a lamp body 3 with a hollow cavity and a bottom plate 5. The inner side of the lamp body 3 is engraved with micro-grooves 15, and the surface of the lamp body 3 is vertically arranged with cooling fins. Sheet 6 and lamp body 3, as the main body of the heat dissipation system, are made of aluminum material with light weight and relatively good heat conduction effect. The present invention designs it as a semi-ellipsoid corrugated type, which itself has both basic heat absorption, basic heat conduction, Main body support and main heat dissipation function; the opening of the inner cavity of the lamp body 3 is provided with a sealing glass plate 4, and a fixing mechanism is arranged in the inner cavity of the lamp body 3, and a liquid for storing heat dissipation medium is formed between the sealing glass plate 4 and the fixing mechanism The working fluid storage cham...

Abstract

The invention discloses an LED lamp body type heat pipe radiating system comprising a lamp body in which a hollow cavity is arranged, an opening of the inner cavity of the lamp body is provided with a sealing glass plate, a fixing mechanism is arranged in the inner cavity of the lamp body, a liquid medium storing cavity for storing a radiating medium is formed between the sealing glass plate and the fixing mechanism, and an LED optical system is arranged in the liquid medium storing cavity, is connected to the surface of the fixing mechanism and faces the sealing glass plate; and a liquid filling hole is arranged at one side of the lamp body and is communicated with the liquid medium storing cavity. A body type heat pipe can be made into any sizes so as to arrange enough radiation area for a lamp; radiating fins of the body type heat pipe can be vertically arranged to avoid dust retention, and rainwater can ensure the cleanness of the radiating fins; the vertically arranged radiating fins have the radiation effect of strengthening natural convection; and the body type heat pipe has the function of rapidly equalizing the temperature of a bottom plate through fluid convection heat transfer.

Description

technical field [0001] The invention relates to the technical field of LED heat dissipation, in particular to a heat dissipation system for high-power white LED lamps. Background technique [0002] High-power LED is the most effective way to convert electrical energy into light energy. It has the advantages of low voltage, low energy consumption, long life, high reliability, easy maintenance, and fast response. It meets the requirements of energy saving and environmental protection for green lighting projects. It is considered It will surely become the fourth-generation lighting source, and the market prospect is very broad. With the improvement and maturity of LED production technology, the advantages and potential of LED as a road lighting source have gradually been affirmed by the road lighting industry. But the problem that LED street lamps need to focus on at present is the problem of heat dissipation. LED is a cold light source, and the heat generated cannot be emitt...
