Heat transfer substrate self-clamping led tube light supported by lampshade

Abstract

The invention discloses a heat transfer substrate self-clamping type LED (light emitting diode) tubular lamp supported by a lamp shade, and a heat radiator of the LED tubular lamp, and belongs to the technical fields of support, suspension or connecting devices of illumination devices. The heat radiator of the LED tubular lamp comprises a heat radiating main body (1) and a heat transfer substrate mounting part (2), wherein the cross section of the heat radiating main body (1) is in a hollow semi-cylinder shape. The heat radiator is characterized in that the heat transfer substrate mounting part (2) is connected with a heat transfer bottom surface (11) and is provided with bar-shaped clamping grooves (21), and the bar-shaped clamping grooves (21) are used for mounting a heat transfer substrate (3). The heat transfer substrate self-clamping type LED tubular lamp supported by the lamp shade has the advantages that as the heat transfer substrate mounting part is provided with the bar-shaped clamping grooves, the heat transfer substrate can be clamped in the bar clamping grooves, and the heat transfer substrate is fixedly arranged on the heat radiator without screws, so the assembling efficiency is high, and the requirement of automatic and quick production is met; the heat transfer substrate is clamped in the bar-shaped clamping grooves and is in contact with multiple surfaces of the bar-shaped clamping grooves, so the heat radiating efficiency is improved, and the heat deformation of the heat transfer substrate is avoided.

Description

technical field [0001] The invention belongs to the technical field of supporting, hanging or connecting devices of lighting devices, and more specifically belongs to a device for efficiently and quickly assembling and connecting LED tube lights. Background technique [0002] At present, LED (light-emitting diode) has been widely used as a new energy-saving light source at home and abroad. In home lighting, company office and outdoor decorative lighting, LED energy-saving lamps, especially LED tube lights, have been widely used. Existing common incandescent tube lamps are an inevitable trend. [0003] The strip-shaped LED tube lamp in the prior art includes a lamp tube and two end caps connected with the lamp tube. The end caps are also called lamp caps. ), a radiator and a semi-pipe-shaped lampshade are assembled together. The length of the lampshade, the heat transfer substrate and the radiator are basically the same, the cross section of the radiator is semicircular, th...

AI Technical Summary

Problems solved by technology

[0006] During the assembly process of the strip-shaped LED tube lamp in the prior art, it is necessary to fix the heat transfer substrate on the radiator with screws, and these tasks are all done manually. Completed, because the work efficiency is low, it cannot meet the high-volume and rapid production; because this work is done manually, it is necessary to manually install the heat transfer substrate on the radiator, and then tighten the screws on the corresponding screw holes. The working process time consuming
