Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome that in the prior art, when the point light source is arranged on the side of the light guide plate, the height of the point light source will far exceed the height of the light-incident side of the light guide plate, so that all the light cannot enter the inside of the light guide plate for guiding. Citing the defects of use, a method for assembling a thin light guide structure and a thin light supply module is provided, which has both extremely low thickness and excellent optical performance, so as to meet the needs of optical products in the current market

Embodiment 1

[0053] Such as figure 1 , figure 2 and image 3 As shown, it is an assembly schematic diagram, an assembly side view schematic diagram and an assembly top view schematic diagram of Embodiment 1 of the present invention. The present invention here discloses a thin light guide structure 1 for use with a plurality of LEDs 20 , and the LEDs 20 are arranged on a substrate 21 . The aforementioned thin light guide structure 1 includes a light guide plate 10 and a reflective sheet 11 .

[0054]The light guide plate 10 has a light incident surface 101, and as mentioned above, the light guide plate 10 can be a light guide plate with an extremely thin thickness. In this embodiment, the thickness of the light guide plate 10 is less than 0.3mm. Preferably, the thickness can be further selected. The light guide plate is about 0.2mm. The reflective sheet 11 has a mounting gap 111 and a bonding area 112, and the opposite sides of the reflective sheet 11 are reflective layers. Preferably...

Embodiment 2

[0060] Such as Figure 5 and Figure 6A ~ Figure 6C As shown, it is a flow chart of steps and a schematic diagram of each assembly step of Embodiment 2 of the present invention. In this embodiment, an assembly method of the thin light supply module 2 is disclosed, which includes the following steps. Firstly, a thin light guide structure 1 as mentioned above is provided. The thin light guide structure 1 includes a light guide plate 10 and a reflective sheet 11, wherein the light guide plate 10 has a light incident surface 101, and the reflective sheet 11 has an installation slit 111 and a bonding area 112, and the opposite sides of the reflective sheet 11 are reflective layers (step S01), such as Figure 6A shown. Next, the side of the light guide plate 10 with the light incident surface 101 is inserted through the installation gap 111, so that the light guide plate 10 and the reflection sheet 11 are stacked in a staggered manner (step S02), as shown in FIG. Figure 6B show...

Abstract

The invention discloses a thin type light guide structure and a method for assembling a thin type light supply module. The thin type light guide structure includes a light guide plate and a reflectorplate, the light guide plate has a light incidence surface, the reflector plate has a mounting gap and a bonding region, and two opposite surfaces of the reflector plate are reflecting layers. One side of the light guide plate, which has the light incidence surface, penetrates through the mounting gap, and the reflector plate and the light guide plate are arranged in a staggered and laminated manner. The thin type light guide structure is assembled with a light source for use, the bonding region of the reflector plate and a substrate of the light source are combined and fixed, so that an LED on the substrate is arranged corresponding to the light incidence surface, light emitted by the LED can be reflected to the light incidence surface via the reflector plate, lateral incidence light is formed relative to the light guide plate, so that LED light is effectively utilized and an LED of a smaller size can be further carried for use, thereby providing an optical product that better satisfies market demand.

Description

technical field [0001] The invention relates to the field of light guide modules, in particular to a thin light guide structure and an assembly method for a thin light supply module. Background technique [0002] The light guide plate is a very common optical component at present. It is generally used with a point light source. The light from the point light source is guided through the light guide plate to form a uniform surface light source, which can be used as a light supply module for various electronic products. The light supply module can be roughly divided into two types: direct-type and side-type according to the position of the point light source relative to the light guide plate. Side; the light incident side of the light guide plate of the side-entry light supply module is located on the side of the light guide plate, and the point light source is correspondingly arranged on the side of the light guide plate to form a side light incident relative to the light gui...
