Abstract

The invention discloses an anti-ultraviolet planar light source optical structure, an anti-ultraviolet diffusion layer and an LED panel light. The optical structure comprises an anti-ultraviolet diffusion layer, a light guiding layer and a reflective layer. The light guiding layer has two opposite surfaces including a back surface and a light emitting surface. The reflective layer is located on the back surface of the light guiding layer, and the anti-ultraviolet diffusion layer is located on the light emitting surface of the light guiding layer. A plurality of light guiding points are arranged between the reflective layer and the light guiding layer. The anti-ultraviolet diffusion layer is a diffusion plate made of an anti-ultraviolet material, and the diffusion plate comprises transparent plastic and master batch, wherein the transparent plastic accounts for 92-99.5% of the total weight of the diffusion plate, and the master batch accounts for 0.5-8% of the total weight of the diffusion plate. The anti-ultraviolet diffusion layer is adopted, which can prevent ultraviolet rays in a surrounding external environment from illuminating the light guiding layer through the anti-ultraviolet diffusion layer; the problems such as deformation, discoloration, yellowing and damage of the light guiding layer due to ultraviolet irradiation can be avoided; the light guiding layer is protected; and the problems such as brightness reduction and uneven brightness of the optical structure can be avoided.

Description

technical field [0001] The invention belongs to the technical field of optical structures, and in particular relates to an optical structure capable of resisting ultraviolet rays and an LED panel lamp. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode) technology has been widely promoted due to its advantages of power saving, high brightness, long service life and good shock resistance. In recent years, LED lamps have been widely used in daily lighting and displays. Such as LED panel lights, this type of LED panel lights are square and planar and the components inside are also planar. The planar reflective layer, light guide layer and anti-ultraviolet diffusion layer are installed in sequence in a rectangular outer frame, and LED strips are installed inside the outer frame and on the side of the light guide layer. Under the joint action of the reflective layer and the light guide layer, the light undergoes multiple reflections to improve uniformit...
