Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] see figure 1 , the edge-type backlight module 10 proposed by the first embodiment of the present invention includes: a light source 11 , a light guide column 13 , a light guide film 15 , an optical film set 17 and a reflection sheet 19 . The light emitting source 11, the light guide column 13 and the light guide film 15 together constitute a surface light source device, wherein the light guide column 13 and the light guide film 15 are separate parts and can be assembled together.

[0025] Based on the above, the light emitting source 11 is, for example, an LED light bar, which includes a strip-shaped PCB board and a plurality of LED lights arranged on the PCB board. Certainly, the light source 11 may also include a strip-shaped...

Abstract

The invention relates to a surface light source device, which is characterized in that a light guide column is additionally arranged between a light emitting source and a light guide film so as to collect light emitted by the light emitting source and transmits the light to a light incoming surface of the light guide film, and the light guide film can be enabled to be small in thickness through a thickness gradually reducing structure design for the light guide column, so that a purpose of reducing the thickness of a traditional light guide plate can be achieved. Furthermore, the surface light source device can be applied to a side entering type backlight module and a display device, and can also be applied to the field of lighting.

Description

technical field [0001] The invention relates to the technical field of light source and display, in particular to a surface light source device and its application. Background technique [0002] In the existing side-type backlight module, the basic structure has a light guide plate, and the volume and weight of the light guide plate account for nearly 50% of the whole machine; if the space and weight occupied by the light guide plate can be reduced, the backlight As far as modules are concerned, costs can be reduced. However, for side-lit backlight modules, directly reducing the volume of the light guide plate means that light may leak out. Contents of the invention [0003] Therefore, the present invention provides a surface light source device and its application, which can reduce the thickness of the light guide plate and prevent light leakage. [0004] Specifically, a surface light source device provided by an embodiment of the present invention includes: a light sou...
