Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp tubes, in particular to a heat dissipation shell for LED lamp tubes. Background Art

[0002] LED lamps have the advantages of low power consumption, good focusing effect, fast response speed, high impact resistance, long service life, and environmental protection, and are favored by people, so they are widely used in the development of lighting. However, the LED light source components of LED lamps will release a lot of heat during the light emission process, and the LED driver components will release a lot of heat during the operation process. If the heat cannot be dissipated in time, it will seriously affect the operation of components, reduce their service life, and also reduce the working efficiency of LED light source components.

[0003] Existing LED lamp tubes generally include a light-transmitting cover, an LED light source assembly, an LED driving assembly and a heat dissipation shell. The light-transmitting cover is connected to the heat dissipation shell, the LED driving assembly is connected to and drives the LED light source assembly to work, and the LED light source assembly and the LED driving assembly are installed on the heat dissipation shell.

[0004] The heat dissipation shell currently used has a number of heat dissipation strips installed on its outer side, and the heat dissipation strips are arranged at intervals along the length direction of the heat dissipation shell. The heat dissipation path is long, and the circumferential diffusion efficiency is low, and the heat dissipation effect cannot be achieved. In addition, the light-transmitting cover is buckled at the lower end of the heat dissipation shell. When removing the light-transmitting cover, it is time-consuming and laborious. Moreover, the light-transmitting cover is generally made of plastic material. Forcibly removing it will easily cause the light-transmitting cover to deform, affecting the subsequent installation and use. Summary of the invention

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this patent application is how to provide a heat dissipation housing for an LED lamp tube that can improve heat dissipation efficiency, facilitate the disassembly and assembly of the light-transmitting cover, and be easy to use.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A heat dissipation shell for an LED lamp tube comprises a long strip-shaped shell body, a heat dissipation plate is fixedly mounted on the shell body, a plurality of heat dissipation fins are fixedly mounted on the heat dissipation plate, the heat dissipation fins are arranged at intervals, the length direction of the heat dissipation fins is arranged perpendicular to the length direction of the shell body, hooks are fixedly mounted outwardly on both sides of the lower end of the shell body, the hooks are L-shaped, a light-transmitting cover is mounted below the heat dissipation shell, the light-transmitting cover is bent inwardly and extended to form a hanging plate connected to the hooks; end connectors are fixed at both ends of the shell body.

[0008] In this way, the heat is transferred to the shell body, the shell body transfers the heat to the heat sink, and the heat sink transfers the heat to the heat sink fins. The heat sink fins are short and numerous, which can increase the contact area with the air and improve the heat dissipation efficiency. Compared with the heat sink fins arranged along the length direction, the heat sink fins arranged perpendicular to the length direction of the present application can reduce the heat dissipation path and quickly dissipate the heat to the surroundings.

[0009] The light-transmitting cover is connected to the outer shell body through a hook and a scraper, which is easy to install.

[0010] Wherein, a plurality of heat dissipation holes are distributed on the heat dissipation fins.

[0011] Among them, the two ends of the shell body have inverted L-shaped mounting frames, the end connecting pieces are penetrated with through holes, the mounting frame is fixed with nut blocks facing the heat dissipation fins, the mounting frame is provided with through holes facing the threaded holes of the nut blocks, and the bolts pass through the end intercepting pieces and the mounting frame and are connected to the nuts.

[0012] Wherein, the end connecting piece has a contoured platform which fits with the light-transmitting cover.

[0013] Wherein, handles are fixed on both sides of the light-transmitting cover.

[0014] Wherein, the shell body is aluminum, copper, aluminum alloy or copper alloy.

[0015] Wherein, the heat dissipation fins are copper sheets.

[0016] In summary, the heat dissipation housing for the LED lamp tube has the advantages of being able to improve heat dissipation efficiency, being easy to disassemble and assemble the light-transmitting cover, and being convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
