Description

A jigsaw puzzle light guide plate

technical field

The utility model relates to a light transmission device, in particular to a jigsaw type light guide plate suitable for various lighting, artistic lighting, decorative lighting, backlight and the like.

Background technique

The design principle of the light guide plate is derived from the liquid crystal display screen of the notebook computer. The light guide plate uses fluorescent lamps, CCFL, and LED light sources to pass through the light guide point or light guide groove calculated according to the optical principle, and under the action of the reflective film (reflector) and the diffusion film, the line light source or point light source is transformed into a surface light source. In order for the light guide plate to emit light evenly, it must pass through various light guide points of different densities and sizes to ensure that the efficiency of light reflection in all directions is basically the same. The purpose of the reflective sheet (reflective plate) is to reflect the light revealed from the bottom surface of the light guide plate back into the light guide plate, so as to improve the efficiency of light use and increase the brightness. Since LED is a point light source, direct use will irritate people's eyes. The existing technology is to transform the point light source into a For surface light source. The function of the diffusion film is to make the light more uniform and softer. The light guide plate has a wide range of applications, such as TV backlight, lighting, decoration, advertisement, signage and so on. Existing light guide plates are all made of monolithic materials, and the trimmed leftover materials cannot be well utilized, resulting in waste of resources. In addition, the shape of the light guide plate does not change much.

Contents of the invention

In order to solve the technical problem that the existing light guide plate is made of a whole piece of material and cannot make good use of the leftover material, resulting in waste of resources, the utility model proposes a puzzle-type light guide plate made of the leftover material.

In order to solve the above technical problems, the utility model proposes a puzzle-type light guide plate, which includes a light guide plate and a light guide point arranged on one side of the light guide plate. The light guide plate is formed by splicing light guide units of various shapes into one body.

Wherein, the light guide unit may be any one of rectangle, triangle and jigsaw figure.

The light guide unit can be made of any light guide material such as acrylic, glass, or PC.

The light guide unit can be made by any method of printing, engraving, molding or etching.

The light guide unit can be bonded together with glue, or can be clamped together by transparent materials arranged on the front and rear sides.

The light guide unit can form three-dimensional components of different shapes.

Compared with the prior art, the utility model has advantages:

1. The existing light guide plates are all in one piece, which cannot make good use of leftover materials and waste resources. However, the utility model can make good use of leftover materials (waste) resources of different sizes, and the light guide plate composed of many pieces of leftover materials has a good effect, reduces waste of resources, improves material utilization rate, and reduces costs;

2. The utility model is more widely used, has craft lighting effect, long service life, energy saving and environmental protection. Products are widely used in various lighting, decorative lighting, handicrafts and other fields.

Detailed ways

Please refer to Fig. 1a and Fig. 1b, the puzzle-type light guide plate proposed by the utility model includes a light guide plate 1 and a light guide point 2 arranged on one side of the light guide plate. The light guide plate 1 is integrally formed by splicing light guide units 3 of various shapes. Wherein, the light guide unit 3 can be in any of various shapes, such as rectangle, triangle, jigsaw figure and so on.

As shown in Figure 1a and Figure 1b, in the first embodiment of the present utility model, small pieces of square light guide units 3 with light guide points 2 of different sizes are spliced into a large square light guide plate in the shape of a "grid". 1. The light source 4 is disposed on a side of the light guide plate 1 .

As shown in Fig. 2a and Fig. 2b, in the second embodiment of the present invention, a circular light guide plate 1 is formed by splicing small puzzle-shaped light guide units 3 with light guide points 2 horizontally and vertically. The light source 4 is disposed on a side of the light guide plate 1 .

As shown in Fig. 3a and Fig. 3b, in the third embodiment of the present invention, small pieces of jigsaw light guide units 3 with light guide points 2 are spliced horizontally and vertically to form a square column-shaped light guide plate 1. The light source 4 is disposed on the upper end and/or the lower end of the square columnar light guide plate 1 . It can also be spliced into light guide plates of other three-dimensional shapes as required.

The light guide units 3 in the above embodiment can be glued together to form a whole light guide plate 1 .

As shown in Figure 4a and Figure 4b, in the fourth embodiment of the present utility model, small pieces of square light guide units 3 with light guide points 2 of different sizes are spliced into a large square light guide plate in the shape of a "grid". 1. The light source 4 is disposed on a side of the light guide plate 1 . Each light guide unit 3 is clamped by transparent materials such as transparent glass 5 or acrylic on the front and rear sides to form an integral light guide plate 1 .

The manufacturing method of the utility model light guide plate, its steps are as follows (please refer to Fig. 1a):

Step 1: Design the required light guide points first, and make light guide points 2 of different shapes, sizes and density distributions on the surface of the collected corner light guide plates. Of course, it is also possible to make light guide points after splicing them into light guide plates, so the effect will not be too good, and sometimes some printed dots will be missed. The light guide point 2 can be made by any method of printing, engraving, molding or etching. The light guide plate is made of any light guide material such as acrylic, glass, or PC.
