Embodiment Construction

[0034] Such as Figure 1 to Figure 10 As shown, the light guide plate with holes proposed by the present invention includes a plate body 1 and a light source 3 disposed on the side of the plate body, and at least one side of the plate body is provided with a light guide hole 2 .

[0035] see image 3 , Figure 4 , the light guide holes 2 of the present invention can be blind holes (different depths) arranged on one or both sides of the light guide plate 1, or a mixture of blind holes and through holes, or all through holes. see Figure 5 ~ Figure 7 , said blind hole or through hole 2 can be a vertical hole or an inclined hole, or a mixed arrangement of vertical holes (90 degrees) and inclined holes (such as 45 degrees, 35 degrees, etc.). The shape of the light guide hole 2 can be a kind of circular hole, elliptical hole or polygonal hole, and can also be any mixed arrangement of vertical hole, oblique hole or polygonal hole. The aperture sizes of the light guide holes 2 ma...

Abstract

The invention discloses a light guide plate with holes, which comprises a plate body (1) and a light source (3) arranged on the side of the plate body. At least one side of the plate body is provided with a light guide hole (2). The invention also discloses a manufacturing method of the light guide plate with holes. The invention makes various types of fine holes on the surface of the light guide plate, uses the difference between the perforation and the direction of the perforation in the light guide plate to adjust the light distribution curve (the light distribution curve of the traditional light guide plate is fixed), and overcomes the problem that the light guide plate must be fixed. Relying on the diffusion plate can be used as an LED panel light to improve the practicability and artistry of the light guide plate.

Description

technical field [0001] The invention relates to a light transmission device, in particular to a light guide plate suitable for various types of lighting, artistic lighting and decorative lighting, decorative materials, showcases, cabinets, display stands, etc. and a manufacturing method thereof. Background technique [0002] 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 ...
