Summary of the invention

The purpose of this utility model is to overcome the existing defective of common LED fluorescent tube, and a kind of LED fluorescent tube that has good heat radiating function, can increase the service life is provided.

To achieve these goals, the utility model adopts following technical scheme: a kind of LED fluorescent tube, include body, be arranged at described body two ends lamp holder, be arranged at the LED lamp bar in the described body and be electrically connected in the lamp pin of described lamp holder and the LED driving power between the LED lamp bar, wherein, described body is made up of the lampshade that a lamp body and by the metal material preparation is engaged in described lamp body.

In the above-mentioned LED fluorescent tube, described lamp body is the aluminium alloy lamp body.

In the above-mentioned LED fluorescent tube, two longitudinal edge places of described lamp body respectively are formed with a clamping flange, and two longitudinal edge places of described lampshade respectively are formed with a clamping groove that is matched with the clamping flange, and described clamping flange is inserted among the described clamping groove.

In the above-mentioned LED fluorescent tube, described LED lamp bar is arranged among the described body by a fixed mount.

In the above-mentioned LED fluorescent tube, two inboards of described fixed mount vertically are formed with the mounting groove that is used to install described LED lamp bar that corresponds to each other.

In the above-mentioned LED fluorescent tube, two outsides of described fixed mount respectively are formed with a flange connector, two inboard places of described lamp body respectively are formed with a connection groove that is matched with described flange connector, and described flange connector is inserted among the described connection groove and described fixed mount is located on the described lamp body.

The beneficial effects of the utility model are: the body of LED fluorescent tube is made up of the lamp body and the lampshade that adopt the metal material preparation, and metal material has higher thermal conductivity factor, so make fluorescent tube have good heat sinking function, therefore, the heat that LED lamp bar is produced can distribute quickly and efficiently via this body, make the operating temperature of body inside be in suitable degree, thereby prolong the service life of LED fluorescent tube.

The specific embodiment

For making those of ordinary skill in the art be expressly understood the purpose of this utility model, technical scheme and advantage more, the utility model is further elaborated below in conjunction with drawings and Examples.

Referring to figs. 2 and 3 shown in, LED fluorescent tube disclosed in the utility model mainly includes a body 10, two are divided into the lamp holder 20 at these body 10 two ends, one is arranged at the LED lamp bar 30 in this body 10, one is electrically connected in the lamp pin 200 of this lamp holder 20 and the LED driving power 40 between the LED lamp bar 30, wherein, above-mentioned body 10 is made up of the lampshade 14 that a lamp body 12 and is engaged in this lamp body 12, lamp body 12 adopts the metal material preparation with good heat conductive performance such as aluminium alloy, and lampshade 14 adopts such as the PC plastics, the transparent or semitransparent material preparation of glass and so on.The light that transparent or semitransparent lampshade 14 capable for LED lamp bars 30 are produced transmits, and it is carried out luminous intensity distribution, and obtains stable, uniform illuminated area light source; Because metal material has higher thermal conductivity factor, and make lamp body 12 have good heat sinking function, the heat that LED lamp bar 30 is produced can distribute fast and effectively via this lamp body 12, makes the operating temperature of body 10 inside be in suitable degree, prolongs the service life of LED fluorescent tube.
