The optical-grade acrylic sheet is used for absorbing the light emitted from the lamp to stay on the surface of the optical-grade acrylic sheet, when the light irradiates each light guide point, the reflected light can be diffused towards each angle, and then the reflected light is damaged and is emitted from the front surface of the light guide plate. The light guide plate can uniformly emit light through various light guide points with different densities and sizes. The reflecting sheet is used for reflecting the light exposed from the bottom surface back to the light guide plate so as to improve the use efficiency of the light; under the condition of equal area brightness, the luminous efficiency is high and the power consumption is low.

2. And (3) diffusion plate: the most important characteristic of the diffuser plate is that the diffuser plate causes great interference to light, no matter how many degrees of the originally designed light distribution curve are, as long as the light passes through the diffuser plate, the light beam angle is 160-176 degrees, so when viewed from the side, the lamp plate surface has a fog feeling, from this point, the light beam angle is as large as 160-176 degrees, the best evidence proves that the larger the light beam angle is, the lower the illumination is, some light can be filtered, some wavelengths can not penetrate, color cast is caused, if the surface is subjected to light interference treatment again (such as frosting and pressing lines), the light transmittance is lower due to the natural phenomenon of geometrical optics, so the base material for making the diffuser plate should be selected to have the lower refractive index, and the lower the light interference is.

3. Light-reflecting paper: the reflective paper is an optical film and is made of various materials: PET PP PVC, and the like. The reflective paper mainly refers to a PET reflective film which is used on an LED lamp and plays a role in reflection. The brightness and lumens of the lamp can be improved.
