Problems solved by technology

The existing technology of secondary injection molding requires high equipment cost, and the material of the frame body and the reflection sheet has different stresses, so that the injected frame body and the reflection sheet are easily pulled and deformed.
In addition, in the above technologies, no matter in the pasting process or the injection molding process, there may be misalignment due to the difficulty in aligning the reflective sheet with the frame

Abstract

The invention discloses a light source module structure which includes a light source module and a lighting tube support. The light source module is mutually connected with the lighting tube support which contains a frame body and a reflector plate. The frame body of the lighting tube support is provided with a joint face which is provided with a plurality of welding concave parts, and the reflector plate is provided with a plurality of welding convex parts which are corresponding to the welding concave parts. The welding convex parts are taken as ultrasound weld lines and the welding concave parts are taken as ultrasound weld slots; the welding convex parts are heated and melted in the welding concave parts in an ultrasound mode so as to lead the welding convex parts and the welding concave parts to be mutually jointed and fixed.

Description

technical field [0001] The invention relates to a light source module structure; specifically, the invention relates to a lamp tube frame applied to the light source module structure. Background technique [0002] Display panels and display devices using thinner display panels have gradually become the mainstream of various display devices. For example, various panel displays, flat-screen TVs for home use, flat-panel monitors for personal computers and laptops, display screens for mobile phones and digital cameras, etc., are all electronic products that use a large number of thin display panels. One of the most important components in the display panel is the structure of the light source module. [0003] A traditional light source module structure includes a light source module and a lamp tube frame. FIG. 1 is a partial schematic diagram of a conventional lamp tube frame 20 . The lamp frame 20 includes a frame body 22 and a reflector 24 . The frame body 22 has a joint s...
