A led backlight module

Abstract

The invention discloses an LED backlight module, which comprises a back plate, an LED light bar and a fixation device that is used to mount the LED light bar on the back plate, wherein the back plate comprises a base surface and a side wall of an incident side; a right-angled bending edge is set on the side wall; the side wall of the back plate, the right-angled bending edge and the base surface are used to form a contain chamber; and the contain chamber is used to fix the fixation device on the back plate. According to the invention, the LED light bar is fixed on the back plate by relying on the fixation device; the LED light bar is first fixed on the fixation device; the fixation device is secondly pushed into the contain chamber on the back plate, so not only the installation efficiency of the LED light bar is improved, but also the LED light bar can be replaced rapidly; in addition, the light bar is attached to the fixation device with good cooling performance, so the cooling performance of the module is improved; and the reliability of the product is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display backlight modules, in particular to a side-entry LED backlight module for convenient replacement of LED light bars. Background technique [0002] In recent years, LED (Light Emitting Diode, light-emitting diode) has been widely used in the field of lighting due to its advantages of no pollution, good color rendering, and energy saving. It is also used in the field of display equipment such as LCD TVs and notebook computer monitors. At present, side-lit LEDs are widely used in the design of backlight modules. [0003] Such as figure 1 As shown, the side-entry LED backlight module 10 includes: a plastic frame 11, an optical film 12, a light guide plate 13, a reflector 14, a back plate 15, and an LED light bar 16; On the long side or the short side, the LED light bar 16 is connected on the long side of the backboard 15, and the LED light bar 16 passes through a metal heat sink 151 (such as f...

AI Technical Summary

Problems solved by technology

When assembling, it is necessary to carefully align the engraved lines on the back panel to paste the LED light strips to avoid light leakage caused by the height deviation of the light strips. At the same time, in order to avoid waste of materials, the LED light strips can only be pasted during assembly, and It is not possible to pre-process the light bar, which greatly affects the assembly efficiency

[0006] When the LED light bar is faulty, it needs to be disassembled against the installation process. The staff must first disassemble the front frame and panel, then disassemble the plastic frame, optical film, light guide plate, reflector, and finally detach the LED light bar from the back board, and then replace the LED light bar, especially the removal of the LED light bar, you need to use a tool to scrape off the double-sided adhesive, and then replace the LED light bar to reinstall, which is very inconvenient, not only affects the production efficiency but also affects the maintenance efficiency
