Next, Shenzhen Xinzhao Photoelectric Technology Co., Ltd. Xiaobian to give you a detailed introduction
Light guide plate is made of optical grade acrylic / PC plate, and then printed with laser engraving, V-shaped cross grid engraving and UV screen printing technology on the bottom surface of optical grade acrylic plate with high reflectivity and non light absorbing high-tech materials. The optical grade acrylic plate is used to absorb the light emitted from the lamp on the surface of the optical grade acrylic plate. When the light hits each light guide point, the reflected light will diffuse to all angles, and then the reflection condition is destroyed and the light is emitted from the front of the light guide plate. The light guide plate can emit light evenly through various light guide points with different density and size. The purpose of the reflector is to reflect the light exposed from the bottom back to the light guide plate, so as to improve the efficiency of light use; Under the condition of the same area brightness, the luminous efficiency is high and the power consumption is low. Single side micro structure array light guide plate is usually fabricated by extrusion molding.
The key of the light guide plate is that the function of the light guide plate is to convert the side light source into the surface light source and make the light uniform.
At present, the common applications of light guide plate are: backlight of LCD, ultra-thin advertising light box, medical X-ray film viewer, flat panel lighting, light efficiency application of lighting engineering, luminous signs and other occasions.
What they have in common is the small volume of the light guide plate and the function of uniform light emission.
