LED light source modules, LED lamp bar and direct type 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 invention relates to a light source in the field of electrical technology, in particular to an LED light source module, an LED light bar and a direct-type backlight module. Background technique [0002] The development trend of the direct type liquid crystal module is an ultra-thin module, that is, the thickness is getting thinner and thinner. Under the current technical conditions, the LED used in the backlight can realize a thick backlight design without a lens lens, and the thickness is generally above 60mm; Its implementation technology is simple, and its cost is comparable to that of side-lit modules, but its thickness has always limited the application of direct-lit modules, because the subjective picture effect can only meet the requirements if the LED light source is given a sufficient mixing distance, and the mixing The requirement of optical distance is just opposite to the requirement of thin module market. [0003] At present, direct-...

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
