Description of drawings

The utility model is described in detail below in conjunction with embodiment and accompanying drawing, wherein:

Fig. 1 is a structural schematic diagram of a light guide plate of the present invention;

Fig. 2 is a schematic diagram of the light guide network points of the light guide plate according to an embodiment of the present invention.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , the light guide plate 1 of the present invention includes a light emitting surface 11 , first light guide dots 12 and second light guide dots 13 . Wherein, the light emitting surface 11 is located on the top surface of the light guide plate 1, the first light guiding dots 12 are printed on the light emitting surface 11, the second light guiding dots 13 are also printed on the light emitting surface, and the first light guiding dots The size and density of the dots are different from those of the second light-guiding dots, so that the brightness of the light passing through the first light-guiding dots and the second light-guiding dots on the light-emitting surface is different.

Of course, the second light guide dots 13 can also be printed on the light guide surface 14 located on the bottom surface of the light guide plate 1 .

The first light guide network point 12 and the second light guide network point 13 constitute various luminescent patterns, including any combination of Chinese characters, letters or graphics or any combination of Chinese characters, graphics and letters. Because the size and density of the printed first light guide dots and the second light guide dots are different, the brightness of the first light guide dot area and the brightness of the second light guide dot area in the pattern formed by it are different, so light and dark can be formed. different graphics.

Light guide points can be in any shape, such as circular, straight, cross and star. These light guide dots of different shapes, sizes or density distributions are combined to form various luminous patterns.

Dyeing materials or self-luminous materials can also be printed on the light-guiding dots of the light guide plate to form dots of dyed materials or self-luminous materials to construct various color luminous patterns or display various luminous patterns without light source illumination.

The light guide plate can be set in different shapes as required, such as flat plate, cylinder, polygonal cylinder and so on. Light guide grid points of different shapes, sizes or density distributions are arranged on the surface of light guide plates of various shapes.

The manufacturing method of the light guide plate of the present utility model is as follows:

Design the required luminous pattern in the early stage, and carry out the art design and plate making of the light guide dots according to the requirements of the pattern. Then print the first light guide dots and the second light guide dots on the side of the acrylic according to the requirements until the entire light-emitting pattern is completed.

The light guide plate of the utility model can be used for various lighting fixtures. This kind of lamp includes a light source and a light guide plate, and light guide dots are arranged on the light exit surface of the light guide plate, and the light guide dots include the first light guide dots printed on the light exit surface and the first light guide dots printed on the light exit surface. Two light guide outlets. The first light guide grid dots and the second light guide grid dots form a light emitting pattern. Dyeing materials or self-illuminating materials are printed on the light guide dots. The light source is preferably arranged on the side of the light guide plate.

Of course, the second light guide dots can also be printed on the light guide surface.
