Embodiment Construction

[0018] The present invention provides a backlight module. In order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Current LCD monitors or LCD TVs can be roughly divided into side-type backlight modules and direct-type backlight modules according to the position of the light source of the backlight. Among them, the LED of the side-type backlight module needs to be used together with the light guide plate, and the LED light source is placed directly on the side of the light guide plate. The LED light strips of the direct-lit backlight module are evenly placed on the bottom surface of the backlight module, and the light is emitted directly upward.

Abstract

The invention discloses a backlight module. The backlight module comprises a plurality of light emitting assemblies for emitting light, a plurality of reflection plates in sequential end-to-end connection to reflect and forwardly diffuse the light emitted by the light emitting assemblies, wherein the reflection plates are semi-arc; and reflection assemblies for reflecting light are arranged on thesemi-arc concave surfaces of the reflection plates. According to the backlight module, the distances between LEDs can be greatly increased, and the overall light emitting effect of the backlight module can be satisfied, so that the problem that the LED light emitting effect cannot satisfy the demands after the distances between the LEDs are increased for reducing the cost in the prior art is solved.

Description

technical field [0001] The invention relates to a light source module, in particular to a backlight module. Background technique [0002] Current LCD monitors or LCD TVs can be roughly divided into side-type backlight modules and direct-type backlight modules according to the position of the light source of the backlight. Among them, the side-type backlight module is difficult to reduce the cost of some key materials, resulting in a relatively high overall cost. The overall cost of direct-type backlight modules is generally lower than that of side-type backlight modules. However, due to the technical bottleneck of LEDs and their supporting optical lenses, increasing the distance between LEDs will continue to reduce the cost of backlight modules. Meet the requirements of the overall light effect of the backlight module. [0003] It can be seen that the prior art still needs to be improved and developed. Contents of the invention [0004] In order to solve the defects in ...
