According to the structure and principle of the light guide plate in the prior art, it can be seen that the light guide points on the light guide plate in the prior art are directly printed on the bottom surface of the light guide plate. This process is very difficult in actual operation, and the yield rate is low. , so the high cost

Embodiment
[0009] Embodiment: a reflective sheet with light guide points, provided with a reflector 1, the reflector 1 has a reflective surface 11, a number of light guide points 2 are printed on the reflective surface 11 of the reflective plate 1, the guide The spot 2 is made of ink. The reflector 1 is made of reflective material.
[0010] It can be seen from the above structure of the reflective sheet of the present invention that the reflective sheet of the present invention not only has the traditional reflective function. And when it is used with a transparent plate (such as acrylic or glass) on its reflective surface, the light is injected from the transparent plate, and when the light hits each light guide point on the back of the transparent plate (ie, the reflective surface of the reflective plate) , the reflected light will diffuse to various angles, and then destroy the reflection condition and emit from the front of the transparent plate, which can convert the line light sou...

The invention discloses a light guiding and reflecting structure, and particularly relates to a reflector plate with light guiding points. The reflector plate with the light guiding points is provided with a transparent substrate and a reflecting plate, wherein a plurality of light guiding points are arranged on the reflecting surface of the reflecting plate, the transparent substrate is stacked on the reflecting surface of the reflecting plate, light is irradiated in from the transparent substrate, when the light irradiates to the light guiding points on the reflecting plate on the back surface of the transparent substrate, the reflecting light can disperse to all angles, then damages the reflecting condition and irradiates out from the front surface of the transparent substrate, so that line light source can be converted into surface light source. In the invention, as the light guiding points are arranged on the reflecting plate, the reflector plate is convenient to manufacture when in production, and is high in yield, and the cost is lowered.
Description
technical field [0001] The invention belongs to the field of optoelectronics, and in particular relates to a reflection plate structure for illumination or display. Background technique [0002] In the prior art, the line light source is converted into a surface light source through a light guide plate. The light guide plate in the prior art uses an optical-grade acrylic (PMMA) plate, and then prints light-guiding points on the bottom surface of the optical-grade acrylic plate with an ink that has a very high reflectivity and does not absorb light. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit li...
