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.
