Abstract

The utility model discloses an LED (Light Emitting Diode) lamp with an improved cooling effect. The LED lamp with the improved cooling effect has the advantages that heat can be dissipated quickly and efficiently, and the service life of the LED lamp is prolonged. The LED lamp comprises a lamp holder, a lamp body, LED lights and a transparent lampshade, wherein the lamp holder is mounted at the top of the lamp body, a base plate is arranged at the bottom of the lamp body, the LED lights are arranged on the lower bottom face of the base plate, the transparent lampshade shades the LED lights, the lamp body is divided into an outer shell body and an inner shell body, a driving circuit is mounted in the inner shell body, and a hermetic chamber is formed between the outer shell body and the inner shell body and is filled with heat transfer liquid.

Description

Improved the LED lamp of cooling effect

Technical field

The utility model relates to a kind of LED lamp that has improved cooling effect.

Background technology

The LED lamp generally all is to be made of lamp holder, lamp body, drive circuit and LED lamp, the LED lamp is mounted on the substrate, drive circuit and LED lamp all can constantly produce heat in the course of the work, if these heats do not loose, can have a strong impact on the life-span of drive circuit and LED lamp, and can influence the stability of drive circuit, the light decay of LED lamp also can be very serious, reduced the effect of illumination.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and providing a kind of can loose heat walk quickly and efficiently, improves the LED lamp LED illuminating lamp in service life.

Problem to be solved in the utility model, can realize by following technical scheme: the LED lamp that has improved cooling effect, include lamp holder, lamp body, LED lamp and Transparent lamp shade, lamp holder is installed at the top of lamp body, and the bottom is provided with substrate, bottom surface at substrate arranges the LED lamp, Transparent lamp shade covers the LED lamp, and lamp body is divided into shell body and inner housing, and drive circuit is installed in the inner housing, be formed with airtight chamber between shell body and inner housing, this airtight chamber is full of heat transfer liquids.

After adopting said structure, compared with prior art, the beneficial effects of the utility model are: by shell body and inner housing are set, between forms airtight chamber, this chamber is full of heat transfer liquids, so just can siphon away the heat of the heat of drive circuit generation in the inner housing and the generation of basic onboard led lamp and be dispersed in the air, greatly improve radiating efficiency.

Description of drawings:

Structure chart when Fig. 1 is the efficient cooling LED illuminating lamp of the utility model underfill heat transfer liquids;

Fig. 2 is the structure chart after the efficient cooling LED illuminating lamp of the utility model is full of heat transfer liquids.

The specific embodiment:

Below in conjunction with accompanying drawing present technique is described further.

The LED illuminating lamp of a kind of efficient cooling of present embodiment includes lamp holder 1, lamp body 2, LED lamp 3 and Transparent lamp shade 4, and lamp holder 1 is installed at the top of lamp body 2, and the bottom is provided with substrate 5, at the bottom surface of substrate 5 LED lamp 3 is set,

Transparent lamp shade 4 covers LED lamp 3, and lamp body 2 is divided into shell body 6 and inner housing 7, and drive circuit 8 is installed in the inner housing 7, is formed with airtight chamber 9 between shell body 6 and inner housing 7, and this airtight chamber 9 is full of heat transfer liquids 10.

The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
