Acrylic diffusion plate, also known as PMMA diffusion plate, is a kind of material with light diffusing property of PMMA (polymethyl methacrylate, alias acrylic, acrylic, plexiglass).
The main characteristics of all kinds of LED special-shaped light guide plates widely used in lighting engineering are as follows.
In the process of using the light guide plate, it is necessary to carry out proper cleaning and maintenance, especially the light box, which must be cleaned regularly to ensure that its luminous effect can better evacuate heat and avoid burning out the lamp.
The production method of the engraved light guide plate and silk screen light guide plate is to print reflective dots or engrave grid lines on a transparent plate according to different sizes and areas, and use the ink dots printed on the surface of the light guide plate or the refraction of the engraved grid lines.
The design principle of the light guide plate originates from the liquid crystal display of notebook computers and is a high-tech product that transforms linear light sources into the surface light sources.
The light guide plate is made of optical grade acrylic/PC sheet, and then the light guide dots are printed on the bottom side of the optical grade acrylic sheet with UV screen printing technology using high-tech materials with high reflectivity and no light absorption.
