Introduction of LED light guide plate
The light-enhancing structure of the LED light guide plate:
The light-enhancing structure of the light guide plate is composed of first and second optical cutting surfaces. The first and second optical cutting surfaces are formed by the surface of the light guide plate obliquely extending a certain distance toward the end of the light guide plate and then contacting each other. The light emitted by the light source arranged at the end of the light guide plate can be emitted toward the expected surface of the light guide plate through the optical refraction of the first optical cutting surface.
And part of the refracted light deflected by the first optical cutting surface can also fall on the second optical cutting surface, and be emitted toward the expected surface of the light guide plate through the optical reflection of the second optical cutting surface, so as to increase the light guide plate Brightness performance effect.
The production method of flat cutting LED light guide plate is divided into three parts
The first is the shape processing of acrylic sheet
The second is stencil production
The third is printing, and the process flow is
a. Acrylic shape processing => original board cutting => mirror planing => forming processing
b. Screen production = dot design => film output => Zhang net
c. Printing => Acrylic cleaning => Printing => Baking (IR) or ultraviolet light (UV) packaging...
