Embodiment Construction

[0019] Figure 1a , Figure 1b The basic structure of the first embodiment of the present invention is shown. The light guide plate manufactured by offset printing includes a light guide plate 1 and light sources 4 arranged on both sides of the light guide plate. One side of the light guide plate is provided with light guide dots of different shapes, sizes or density distributions by means of offset printing. In this embodiment, the larger cylindrical light guide dots 3 and the smaller rectangular light guide dots 2 form grid patterns with different shades. Light guide points can be in any shape, such as circular, straight, cross and star. These light guide dots 2 and 3 with different shapes, sizes or density distributions are combined to form various graphics and texts. Graphics and texts can be any one of Chinese characters, letters or patterns, or any combination of Chinese characters, patterns, and letters.

Abstract

The invention discloses a light-guiding plate made by using an offset printing method, which comprises a light-guiding plate, wherein one side surface of the light-guiding plate is provided with light-guiding dots with different shapes, different sizes or different density distributions by using the offset printing method, and the light-guiding dots with different shapes, different sizes or different density distributions are combined to form various pictures and texts. The invention also discloses a making method of the light-guiding plate. Various pictures and texts are formed on the light-guiding plate through the light-guiding dots with different shapes, different sizes or different density distributions, thus the glare problem can be solved without using diffusion materials and light rays emit directly, the energy consumption is reduced, the lighting effect is reinforced and the cost is reduced. The invention has the advantages of more extensive scope of application and value of artistic appreciation.

Description

technical field [0001] The invention relates to a light transmission device, in particular to a light guide plate made by offset printing and a manufacturing method thereof which are suitable for various types of lighting, artistic lighting and decorative lighting, decorative materials, showcases, cabinets, display stands and the like. 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 th...
