Abstract
A high-power LED lamp solves the radiating problem of the high-power LED lamp in the prior art. The adopted technical scheme is as follows: the lamp comprises a glass lamp shell, an LED illuminant, an LED driving chip, an insulating connecting body and a lamp holder, wherein the LED illuminant is arranged in the glass shell; the LED illuminant and the LED driving chip are connected with the lamp holder; the LED illuminant is arranged on a metal heating body through a heating conductor; the inner cavity of the metal heating body is connected with the lamp holder through the insulating connecting body; the input end of the LED driving chip is connected with the lamp holder; the LED driving chip is arranged in the metal heating body and the insulating connecting body; the output end of the LED driving chip is connected with the LED illuminant; and a glass lamp shell connecting ring is connected with the metal heating body. The utility model has the advantages that the structure is simple, and the LED driving chip is not influenced by heat generated by the LED lamp, thereby ensuring the environmental working temperature of the LED illuminant and the LED driving chip and greatly prolonging the service life of the LED lamp.
Description
Technical field
The utility model relates to a kind of LED modulated structure, particularly high-power LED lamp structure.
Background technology
In the prior art, the LED light fixture has low power consuming, long lamp plurality of advantages of life-span, be widely used in lighting field, use high-powered LED lamp because heat dissipation problem particularly uses the heat dissipation problem of the bulb of great power LED also not have desirable solution in the prior art, in the structure of high-powered LED lamp, the heat effects LED lamp that the work of LED lamp produces drives the operate as normal of chip, has reduced LED lamp service life.
Summary of the invention
In order to solve the insurmountable shortcoming and defect of high-powered LED lamp heat dissipation problem of prior art, this practical utility model designs a kind of high-power LED lamp structure, overcomes the deficiencies in the prior art.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of high-powered LED lamp, comprise: glass lamp housing, the LED illuminator, LED drives chip and drives insulator and lamp socket, the LED illuminator is arranged in the glass lamp housing, the LED illuminator, LED drives chip and is connected the lamp socket electrical connection, described LED illuminator is arranged on the heat dissipation metal body through heat carrier, the heat dissipation metal intracoelomic cavity is connected with lamp socket through the insulation connector, and the input that LED drives chip is connected with lamp socket, and LED drives chip and is arranged in heat dissipation metal body and the edge connector, the output that LED drives chip is connected with the LED illuminator, and glass lamp housing is connected with the heat dissipation metal body through connecting ring.
The beneficial effects of the utility model are, simple in structure, the heat that the LED illuminator produces in time sheds through the heat dissipation metal body, and LED drives the heat effects that chip is not produced by the LED lamp, guarantee that LED illuminator and LED drive the ambient operating temperature of chip, prolonged LED lamp service life greatly.
Description of drawings
Accompanying drawing 2 is the utility model schematic diagram.
In the accompanying drawing, the 1LED illuminator, 2 heat carriers, 3 heat dissipation metal bodies, 4 insulation connectors, 5 lamp sockets, 6LED drives chip, 7 glass lamp housings, 8 connecting rings, 9 heat radiations are protruding.
The specific embodiment
Referring to accompanying drawing, a kind of high-powered LED lamp, the structure of this lamp is, LED illuminator 1 is arranged on the heat dissipation metal body 3 through heat carrier 2, heat dissipation metal body 3 inner chambers are connected with lamp socket 5 through insulation connector 4, the input that LED drives chip 6 is connected with lamp socket 5, and the output that LED drives chip 6 is connected with LED illuminator 1, and glass lamp housing 7 connecting rings 8 are connected with heat dissipation metal body 3.
During work, the heat that LED illuminator 1 produces is transmitted on the heat dissipation metal body 3 through heat carrier 2, heat dissipation metal body 3 sheds heat, because heat dissipation metal body 3 radiating efficiency height, so LED drives the heat effects that chip 6 is not produced by LED illuminator 1, the service life of improving high-powered LED lamp greatly.
For improving heat dissipation metal body 3 radiating efficiencys, on the outer surface of heat dissipation metal body 3, be provided with heat radiation projection 9.Projection 9 can adopt various different convex shape.
For improving the heat transfer efficiency and the service life of heat carrier 2, the utility model embodiment heat carrier 2 is the silica gel heat carrier.
