LED backlight module

Abstract

The invention relates to the technical field of backlight modules, and further discloses an LED backlight module that includes an outer frame; a cooling fan is mounted in the extension shell; a firstgroove is formed in the middle position of the surface of the extension shell; a second groove is formed in the surface of the extension shell under the first groove; a fixing frame is arranged in thefirst groove, a dustproof net is installed at the position of the fixing frame; an installation cover is arranged in the position, on one side of the fixing frame, of the first groove; anti-skid stripes are arranged on the surface of the installation cover, external threads are arranged on the outer side face of the installation cover, and internal threads are arranged on the inner wall of the first groove. According to the LED backlight module, through the arrangement of the cooling fan, the dustproof net and the installation cover, the LED backlight module has the functions of heat dissipation, dust prevention and convenient disassembly and assembly, so the heat dissipation efficiency of the module body is improved, the module body is effectively prevented from being burnt out by high temperature, the service life is prolonged, meanwhile, workers can clean the dustproof net conveniently and regularly, and the dustproof efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to LED backlight modules. Background technique [0002] The backlight module is one of the key components of the LCD panel. Its function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. The so-called backlight is a kind of light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. Liquid crystal itself does not emit light, it displays graphics or characters as a result of its modulation of light. The backlight module is the provider of the light source of the liquid crystal display. The LCD itself does not emit light. Can occupy a place in the CRT market. [0003] At present, because the backlight module is between the parts of the LCD panel, and the thickness of the LCD panel body is small, the backlight module ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an LED backlight module, which has the advantages of heat dissipation, dustproof and convenient disassembly and assembly functions, and solves the problem that the existing backlight module will generate a certain amount of heat during use, and the Without treatment, it will affect the service life of the backlight module, and even burn out. At the same time, because the backlight module is installed inside the liquid crystal display panel, and the thickness of the liquid crystal panel is small, the existing heat dissipation is in the liquid crystal display. There are heat dissipation holes on the surface of the panel, and it is easy for dust in the air to enter the interior of the device through the heat dissipation holes, thereby affecting the normal operation of the internal electrical components
