Abstract

The utility model discloses an improved structure of a tube lamp, which mainly consists of a lamp shade, an LED lamp, a heat conducting cover, a lamp seat and a heat radiation seat, wherein the LED lamp is connected in the lamp seat, the lamp seat is arranged on the heat radiation seat, both ends of the heat conducting sleeve are respectively sheathed and connected on a connecting seat arranged on the heat radiation seat and a heat radiation casing of the LED lamp, and the lamp shade is fixed on the end surface of the heat radiation seat. Because the utility model is additionally provided with a middle heat conducting body of the heat conducting sleeve between the LED lamp and the heat radiation seat, the original fixed seat is changed into the heat radiation seat made of metal materials, the heat radiated by the LED lamp can be directly conducted to the heat radiation seat through the heat conducting sleeve, the heat radiated by the LED lamp can be fast radiated out, the heat radiation effect is good, and in addition, the structure is simple.

Description

The improvement structure of Down lamp

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of improvement structure of Down lamp.

Background technology

The Down lamp of commonly using (as shown in Figure 1) mainly is made up of lampshade 1 ', LED lamp 2 ', lamp socket 3 ' and holder 4 '.This LED lamp 2 ' is screwed onto in the lamp socket 3 ', and lamp socket 3 ' is installed on the holder 4 ', and tubular lampshade 1 ' snaps onto holder 4 ' and goes up to form Down lamp.

But this Down lamp of commonly using in use, and LED lamp 2 ' can distribute a large amount of heat in place, if these heats can not effectively leave, can shorten the service life of LED lamp 2 ', even cause the 2 ' damage of LED lamp, and present Down lamp radiating effect is not good.For this reason, need design the structure that LED lamp 2 ' heat is distributed as early as possible.

The utility model content

The purpose of this utility model provides the improvement structure of a kind of good heat dissipation effect, Down lamp simple in structure.

For achieving the above object, solution of the present utility model is:

A kind of improvement structure of Down lamp, it comprises the tubular lampshade, have the lamp socket of the LED lamp of radiating shell, cooperated with LED lamp and cooperate lampshade and the holder of LED lamp, lamp socket; Wherein: this holder is provided with radiating fin, and the radiating shell of LED lamp is connected with holder by a heat conduction cover.

Be distributed with several radiating fins on the bottom lateral margin of described holder.

Described heat conduction cover is a Cylinder shape constructional element, and the one end is provided with a plurality of protruding pin and is the grizzly bar shape and places radiating shell to form just to cooperate to stretch, and the other end just is socketed on the holder.

Described heat conduction cover inner chamber middle part is provided with a toroidal membrane, and the middle part of this toroidal membrane is provided with the through hole that the lamp holder for the LED lamp passes, and the top of toroidal membrane and holder against.

After adopting such scheme, because the utility model has been set up an intermediate thermal conductivity body-heat conduction cover between LED lamp and holder, and will on original holder radiating fin be set, the direct guide securement seat of heat that the LED lamp is sent by the heat conduction cover, make that heat that the LED lamp sends can very fast distributing, good heat dissipation effect and simple in structure.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is axonometric drawing and a three-dimensional exploded view of commonly using Down lamp;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is an axonometric drawing of the present utility model;

Fig. 4 is the axonometric drawing of heat conduction cover of the present utility model.

The specific embodiment

Shown in Fig. 2,3, the utility model is a kind of improvement structure of Down lamp, and it comprises tubular lampshade 1, LED lamp 2, lamp socket 3, holder 4 and heat conduction cover 5.

The both sides of described tubular lampshade 1 are provided with elastic fastening hook 11 to be clasped with holder 4;

Described LED lamp 2 is provided with radiating shell 21, its underpart be provided with matching thread with lamp socket 3 threaded;

Described holder 4 middle parts are provided with the pedestal (not shown) that cooperates lamp socket 3, and promptly lamp socket 3 is to be nested with in this pedestal;

Key of the present utility model is: be distributed with several radiating fins 41 on the lateral margin of the bottom of this holder 4, and the radiating shell 21 of LED lamp 2 is connected with holder 4 by heat conduction cover 5 also; This heat conduction cover 5 is a Cylinder shape constructional element, and the one end is provided with a plurality of protruding pin 51 and is the grizzly bar shape to stretch formation cooperation just between each fin that places radiating shell 21, and the other end just is socketed on the holder 4; In addition, this heat conduction is overlapped 5 inner chambers middle parts and is provided with a toroidal membrane 52, and the middle part through hole of this toroidal membrane 52 can allow the lamp holder of LED lamp 2 pass, and the top of toroidal membrane 52 and holder 4 against.

Tubular lampshade 1 utilizes its elastic fastening hook 11 to snap onto on the holder 4.

Owing to set up an intermediate thermal conductivity body-heat conduction cover 5 between LED lamp 2 and the holder 4, and on holder 4, be provided with radiating fin 41, make the heat of LED lamp 2 be passed to holder 4 places timely by heat conduction cover 5, and in time heat is distributed by radiating fin 42, make the radiating effect of whole bulb lamp better and simple in structure, to improve the service life of big bulb lamp; In addition, heat conduction cover 5 is the setting of the protruding pin 51 of grizzly bar shape, helps cross-ventilation, further improves radiating efficiency.

Emphasis of the present utility model just is: on the holder with original Down lamp radiating fin is set, has set up an intermediate thermal conductivity body-heat conduction cover simultaneously between LED lamp and holder.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
