LED light guide board knowledge

Introduction to the light guide:

The design principle of the light guide plate is derived from the liquid crystal display of the notebook computer, and is a high-tech product that converts the line light source into a surface light source. The optical grade acrylic is the substrate, and the backlight module technology of the LCD display and the notebook computer is used to calculate the light guiding point of the light guiding point through the computer to calculate the light guiding point, so that the light of the light guiding plate is refracted into a surface light source. The light state is manufactured by molding. The product is combined with the principle of spectral analysis and digital UV printing technology and is produced under constant temperature, constant humidity and dust-free environment. It has the characteristics of ultra-thin, super bright, uniform light guiding, energy saving, environmental protection, no dark area, durable, not easy to yellow, simple and quick installation and maintenance.

Light guide plate working principle:

The light guide plate uses an optical grade acrylic sheet, and then uses a high-tech material with extremely high reflectivity and no light absorption to print the light guiding point on the bottom surface of the optical grade acrylic sheet by UV screen printing technology. The optical grade acrylic sheet is used to absorb the light from the lamp to stay on the surface of the optical grade acrylic sheet. When the light hits the respective light guiding points, the reflected light will diffuse to various angles, and then the reflective condition is destroyed by the light guide plate. Shot from the front. The light guide plate can be uniformly illuminated by various light guiding points of different sizes and sizes. The purpose of the reflective sheet is to reflect the light exposed from the bottom surface back into the light guide plate to improve the efficiency of light use.

Light guide plate features :

1. It can be cut to the required size or spliced, the process is simple, the production is convenient. 2. The light conversion rate is high (more than 30% higher than the traditional board), the light is even, and the long life can be used normally for more than 8 years. , safe and environmentally friendly, durable and reliable, both indoors and outdoors can be applied. 3. The same area of ​​light brightness, high luminous efficiency, low power consumption 4. Can be made into special shapes, such as circular, elliptical, arc, triangle, etc. 5. Equal brightness Under, you can use the thin products to save costs. 6. You can use any light source, line light source for surface light source conversion, the light source includes LED , CCFL (cold cathode lamp), fluorescent tube and so on. (Edit: Technology)
