Abstract

The utility model relates to an LED straight type lamp tube, which belongs to a lighting lamp, and comprises a tube body, an aluminum lamp cover and an LED lamp strip with an aluminum base strip, wherein the LED lamp strip with the aluminum base strip is arranged in the tube body, the LED lamp strip and the tube body are movably connected in a snap-in mode, any one end of the aluminum base strip of the LED lamp strip is respectively extended into an inner cavity of the lamp cover from a port of the tube body, and is contacted with the inner surface of the lamp cover. Because the LED lamp strip is contacted with the inner surface of the aluminum lamp cover, the heat energy produced by the lamp strip is rapidly sent out through heat conduction of the lamp cover, thereby keeping the work temperature of an LED in the tube body in a proper range, and prolonging the service life of the LED lamp tube.

Description

The LED straight light tube

[technical field]

The utility model relates to a kind of straight pipe type lighting device, and particularly a kind of is the LED straight light tube of light emitting source with LED.

[background technology]

LED solid luminescence device is low because of its power consumption, characteristics such as light efficiency is high, long service life, non-easy damaged are widely used for developing all kinds of environmental protection lightings, and the LED straight lighting fixture is exactly a class wherein.Common LED fluorescent tube comprises body, is configured in a pair of light cover at body two ends, places the LED lamp bar in the body, is connected pin on the light cover and the led drive circuit between the LED lamp bar and constitutes.Its middle tube body adopts glass transparent pipe or plastic, transparent pipe, and LED lamp bar is made up of printed wiring board and a plurality of LED.This class LED fluorescent tube, because the thermal conductivity factor of the body of plastics or glass material is lower, the heat that LED lamp bar is produced is difficult to effectively distribute, cause the heat accumulation in the body, temperature raises, and LED works under overtemperature for a long time, will speed up it and wear out reduction of service life.

[summary of the invention]

At above-mentioned existing in prior technology problem, the purpose of this utility model is to provide a kind of can effectively distribute the LED straight light tube that increases the service life with the heat that the LED in the body produces.

Technical solution of the present utility model is: a kind of LED straight light tube, comprise body, and be fixed on the pair of aluminum matter light cover on the body two ends, insert the LED lamp bar in the body, this LED lamp bar has one aluminium base, is snap-in flexible connection between it and the body; Aluminium base arbitrary end of described LED lamp bar puts in the inner chamber of light cover and with the light cover inner surface from the port of body respectively and contacts.

A plurality of fin are arranged on the outer circumference surface of described light cover.

Snap-in flexible connection between aluminium base of described LED lamp bar and the body has and is located at the T-shape groove that its length direction of aluminium base upper edge extends, have on the inboard wall of tube body extend radial projection along its length support wall accordingly with the T-shape groove, the T-shape groove on described aluminium base is fastened in outside the support wall on the body.

After adopting said structure, because aluminium base of LED lamp bar contacts with aluminium matter light cover inner surface, and aluminum material has the good heat transfer performance, thereby the heat that LED lamp bar produces can contact hot the conduction with light cover by aluminium base, outwards distribute rapidly, and the fin on the light cover, increased again and the air heat exchange area, help heat radiation, thereby the operating temperature of the LED in the body is in the scope of application, with the service life of prolonging lamp tube.Owing to adopted the T-shape slot type to flexibly connect between LED lamp bar and the body, cross section is " floating empty " state that "T"-shaped support wall can make the lamp bar be in not contact with inboard wall of tube body, thereby can eliminate or obviously reduce LED lamp bar during work and on tube body wall, stay visual shadow region or lines, the brightness of whole fluorescent tube is shown evenly.

Fig. 1 is the partial sectional view of the utility model LED straight light tube structure.

Fig. 2 be Fig. 1 along A-A to cutaway view.

[specific embodiment]

By Fig. 1 and Fig. 2 as can be known, the utility model LED straight light tube comprises body 1, is fixed on the pair of aluminum matter light cover 2 at body two ends; Place the LED lamp bar 4 of body 1 to form.Wherein LED lamp bar by aluminium base, attached to forming with the copper foil circuit of its insulation and a plurality of LED elements 5 that are connected on the copper foil circuit on aluminium base the face.The LED element can be LED veneer tube core or led chip or module.

Body 1 is the pipe of being made by translucent or milky plastic material such as PC material.It is the T-shape groove 7 that T-shape extends along its length direction that its cross section is arranged on aluminium base 6 of LED lamp bar 4.

Radial projection arranged on body 1 inwall along its length with T-shape groove 7 corresponding support walls 8, T-shape groove 7 is enclosed within outside the support wall 8 on the body 1 on aluminium base 6, forms the snap-in flexible connection between LED lamp bar 4 and the body 1.

Aluminium base 6 arbitrary end of above-mentioned LED lamp bar 4 puts in the inner chamber of light cover 2 from the port of body 1 respectively, and contacts with the inner bottom surface of light cover 2.Simultaneously, on the outer circumference surface of light cover 2, be provided with 3～4 fin 3.

In the last example, LED lamp bar 4 also can adopt oat tail groove structure to be connected with the snap-in flexible connection between the body 1.

The utility model LED straight light tube, the heat that LED lamp bar 4 in the body is produced can outwards distribute rapidly by aluminium base the 6 heat conduction with light cover 2, the operating temperature of LED in the body is in the optimum range, thereby prolongs the service life of LED straight light tube.
