The light guide plate uses optical grade acrylic sheet, and then uses high-tech materials with extremely high reflectivity and non-light absorption, and UV screen printing technology is used to print the light guide dots on the bottom surface of the optical grade acrylic sheet.
What is the material of the acrylic light guide plate:
The main material of acrylic light guide plate is optical acrylic plate. Acrylic light guide plates currently produced differ in quality due to the different processes of different manufacturers. In particular, although recycled plates are cheap, they are easy to yellow and have poor transmittance. Acrylic light guide plates should be used to produce acrylic light guide plates that are not easy to yellow and transmit light. Transparent board with a rate of 92%-93% or more.
At present, the light guide plates on the market are made of two kinds of materials: acrylic sheet and PC sheet. However, the most common ones are light guide plates made of acrylic board materials, and there are fewer light guide plates made of PC board materials, and they must be customized, not every manufacturer that makes light guide plates.
How does the acrylic light guide plate work?
The light guide plate uses optical grade acrylic sheet, and then uses high-tech materials with extremely high reflectivity and non-light absorption, and UV screen printing technology is used to print the light guide dots on the bottom surface of the optical grade acrylic sheet.
Use optical grade acrylic sheet to absorb the light emitted from the lamp and stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will diffuse in all angles, and then destroy the reflection conditions. The front side of the acrylic light guide plate Projected.
Through a variety of dense and different light guide points, the acrylic light guide plate can emit light evenly. The purpose of the reflective sheet is to reflect the light exposed on the bottom surface back into the acrylic light guide plate to improve the efficiency of light use.
There are two main methods for making acrylic light guide plates:
Screen printing and non-printing. The screen-printed light guide plate has low investment, no need to invest in equipment, can be operated manually, low cost, high production efficiency, and the technical process is very easy to master.
Non-printed light guide plates, such as laser dots, require large investment, require professional equipment, high production costs, and low production efficiency.
