Abstract

The utility model discloses a heat pipe type light-emitting diode (LED) lamp with a good cooling effect, and the service life of the LED lamp is prolonged. The heat pipe type LED lamp comprises an LED lamp body, a radiating substrate, and a heat abstractor, wherein a cooling fin on the heat abstractor is connected with a radiating tube; the LED lamp body is arranged at one side of the radiating substrate; a heat-absorbing base plate is arranged at the other side of the radiating substrate; a heat-absorbing tube is embedded into the heat-absorbing base plate; two ends of the heat-absorbing tube are communicated with two ends of the radiating tube to form a loop; liquid heat-conducting mediums are filled into the heat-absorbing tube and the radiating tube. Heat generated when the LED lamp works is transmitted to the heat-absorbing base plate by the radiating substrate disclosed by the utility model, the liquid heat-conducting medium inside the heat-absorbing tube can timely take away heat absorbed by the heat-absorbing base plate, and the heat is transmitted to the cooling fin through the radiating tube and then sent out to air by the cooling fin. Compared with an existing heat abstractor, the heat pipe type LED lamp has a good cooling effect by adopting the radiating mode. The service life of the LED lamp can be effectively prolonged.

Description

A kind of heat pipe-type LED lamp

Technical field

The utility model relates to a kind of LED lamp, particularly a kind of heat pipe-type LED lamp.

Background technology

The advantages such as energy-conservation, the long service life of LED lamp are well-known, but the principal element that affects LED lamp service life is heat dissipation problem, and the radiating mode of existing LED lamp mainly contains natural heat dissipation, finned heat radiation, installs fan etc. additional, for low power LED lamp, can also meet reluctantly heat radiation needs, for high-power LED lamp, such as LED street lamp, workshop LED lamp, need to there is a good radiating effect to seem even more important, can extend like this service life of LED lamp.

Summary of the invention

The heat pipe-type LED lamp that the technical problem that the utility model solves is to provide a kind of good heat dissipation effect, can extends the service life of LED lamp.

The technical solution of the utility model completes like this, a kind of heat pipe-type LED lamp, include LED lamp, heat-radiating substrate, heat abstractor, fin on described heat abstractor is connected with radiating tube, LED lamp is located at the one side of heat-radiating substrate, and the another side of heat-radiating substrate is provided with heat absorption base plate, in heat absorption base plate, is inlaid with endothermic tube, endothermic tube two ends are communicated with respectively formation Yi Ge loop with radiating tube two ends, be filled with mobility heat-conducting medium in endothermic tube and radiating tube.

At least be provided with three and be communicated with by endothermic tube and radiating tube the suction heat-sink unit forming.

Described endothermic tube two ends are communicated with left side tube connector, right side tube connector respectively, and radiating tube two ends are communicated with left side tube connector, right side tube connector respectively.

Described heat absorption base plate is aluminium alloy plate.

Described endothermic tube and/or radiating tube are copper pipe.

Described mobility heat-conducting medium is R134A or R410A.

Described fin one side is provided with fan.

Technique effect of the present utility model is: the heat producing when LED lamp is worked due to heat-radiating substrate of the present utility model passes to heat absorption base plate, the heat that mobile heat-conducting medium in endothermic tube can absorb heat absorption base plate is in time taken away, by radiating tube, transfer heat to fin, fin again by dissipation of heat in the middle of air, this radiating mode is compared with existing heat abstractor, there is good radiating effect, can effectively extend the service life of LED lamp.
