Embodiment Construction

[0014] See Figure 1a , Figure 1b The light guide plate with graphics provided by the present invention includes a polygonal light guide plate 1, a light source (not shown in the figure) arranged on the side end of the light guide plate, and a light guide point 2 arranged on one side of the light guide plate. The light guide point 2 part of the light guide plate and the part 3 without the light guide point are combined to form various patterns and / or characters.

[0015] Such as Figure 1a , Figure 1b As shown in the first embodiment of the present invention, the part of the light guide point 2 on the light guide plate 1 and the part 3 where the light guide point is not provided constitute a pattern of "birds standing on a branch".

[0016] Such as Figure 2a , Figure 2b As shown in the second embodiment of the present invention, the part of the light guide point 2 on the light guide plate 1 and the part 3 where the light guide point is not provided form a "square grid" pattern.

Abstract

The invention discloses a light guide plate with graphics, which comprises a light guide plate (1) and a light guide point (2) arranged on one side surface of the light guide plate, the part on the light guide plate, provided with the light point (2), and a part (3) on the light guide plate, which is not provided with the light guide point, are combined to form various patterns and / or characters. On the light guide plate, the luminous light guide point part and the non-luminous part without being provided with the light guide plate form different patterns and characters, i.e. the glare problem can be solved without using a dispersing material, and the light can be directly emitted, therefore, the energy consumption is reduced, the light efficiency is improved and the cost is lowered.

Description

Technical field [0001] The invention relates to a light transmission device, in particular to a light guide plate that can be widely used in commercial and household practical lighting and decorative lighting lamps, ornaments, handicrafts, exit signs, guide lights, advertising light boxes and the like. Background technique [0002] The design principle of the light guide plate is derived from the LCD screen of a laptop computer. The light guide plate uses fluorescent lamp, CCFL, LED light source 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 (reflection plate) and the diffusion film, the linear light source or point light source is converted into a surface light source. In order to make the light guide plate emit light uniformly, it is necessary to pass through a variety of dense and different light guide points to ensure that the efficiency of light reflection in all direction...
