An LED light source module, an LED light bar, and a direct-lit backlight module

Abstract

The invention discloses LED light source modules, an LED lamp bar and a direct type backlight module. Each LED light source module comprises an LED light source and a bottom plate used for bearing the LED light source, wherein two or more lenses are embedded in the LED light source, and the center lines of the two or more lenses coincide with the center line of the LED light source. According to the technical scheme, the two or more lenses are embedded in each LED light source, so that the light-emitting angle of light rays from the corresponding LED light source module is enlarged, according to the LED lamp bar comprising the multiple LED light source modules, the use number of the LED light sources can be reduced by increasing the distance between every two adjacent LED light source modules, and cost is reduced; the thickness of the direct type backlight module comprising the LED lamp bar is within the range of 15 mm, light rays emitted by the LED light sources are evenly diffused on a diffuser plate, and the purpose of improving the subjective effect is achieved.

Description

Technical field [0001] The present invention relates to a light source in the field of electrical technology, and particularly relates to an LED light source module, an LED light bar and a direct type backlight module. Background technique [0002] The development trend of direct-lit LCD modules is ultra-thin modules, that is, thinner and thinner. Under the current existing technical conditions, the LED used in the backlight can realize a thick backlight design without a lens, and the thickness is generally above 60mm; with the development of technology, the direct type adopts no light guide plate The realization technology is simple, and the cost can be comparable to that of the side-light type, but its thickness has always been limited to the application of direct-type modules, because only by giving the LED light source enough light mixing distance, its subjective picture effect will meet the requirements, and the mixed The requirement of optical distance is just the opposite...

AI Technical Summary

Problems solved by technology

[0003] At present, direct-lit backlight modules use a single LED light source combined with a single lens lens, but the existing technical solutions basically focus on optimizing the lens lens used by the LED light source. Not only the implementation method is complicated, but also there are certain Due to the limitations of the direct type module, it is basically impossible to fully realize the further reduction of the thickness of the direct type module
