Description

Technical Field

[0001] The utility model relates to the technical field of lamp tubes, in particular to an LED lamp tube which is convenient for heat dissipation. Background Art

[0002] The LED light source component of the LED lamp tube will release a lot of heat during the light emission process, and the LED driver component will release a lot of heat during the operation process. If the released heat cannot be dissipated in time, it will seriously affect the operation of the components, reduce their service life, and also reduce the working efficiency of the LED light source component.

[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] When assembling the LED lamp tube currently in use, the LED light source assembly is close to the heat dissipation housing, and the heat dissipation housing only relies on the heat dissipation fins arranged on the outside thereof to dissipate heat, and the heat transfer efficiency is low, which cannot meet the heat dissipation requirements. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide an LED lamp tube that can allow heat to flow quickly, better extend the service life, and is simple, stable, and easy to dissipate heat.

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

[0007] An LED lamp tube for heat dissipation includes a heat dissipation shell, an LED light source assembly, an LED driving assembly, a light-transmitting cover, and two end connectors; the LED driving assembly is connected to and drives the LED light source assembly to work, the LED light source assembly and the LED driving assembly are mounted on the heat dissipation shell, and the end connectors are mounted at both ends of the heat dissipation shell.

[0008] The heat dissipation shell is in the shape of an elongated strip and includes a frame, a plurality of heat dissipation fins arranged at intervals are fixed to the upper end of the frame, a lower plate is arranged at intervals at the lower end of the frame, the middle part of the lower plate is sunken to form a sinking platform, a plurality of clearance holes are opened on the sinking platform, and both sides of the lower plate are connected to the light-transmitting cover.

[0009] In this way, when the LED light source assembly is working, the heat generated by the LED light source assembly and the LED driver assembly flows upward. Through the setting of the give-way holes, the heat can better pass through the give-way holes and continue to dissipate upward, and the heat is quickly dissipated through the heat dissipation fins above the bracket, quickly taking away the heat close to the LED light source assembly and the LED driver assembly, thereby improving the heat dissipation effect.

[0010] Wherein, the heat dissipation fins are provided with heat dissipation holes.

[0011] Wherein, lower heat dissipation parts are fixed on both sides of the lower plate, and the lower heat dissipation plate is provided with a plurality of heat dissipation slots.

[0012] Among them, the outer side of the lower cover is provided with a hook, and the light-transmitting cover is bent inward to form a hook, and the hook and the hook can be slidably matched and hooked.

[0013] Wherein, the main frame is fixed with a connecting plate, a nut is fixed on the inner side of the connecting plate, a through hole is opened in the connecting plate opposite to the threaded hole of the nut, and the end connector is connected to the nut by a screw.

[0014] Wherein, the frame, the lower plate, the heat dissipation fins and the lower heat dissipation part are all integrally formed by profiles.

[0015] In summary, the LED lamp tube that is easy to dissipate heat has the advantages of enabling heat to flow quickly, better extending the service life, and being simple and stable. BRIEF DESCRIPTION OF THE DRAWINGS
