Specifically, when light is projected onto the surface of the reflective film 310, most of the light is surface-reflected because the reflective film 310 has an opacity of 99% or more. The incident light and the reflected light of the reflective film 310 are in one-to-one correspondence, and specular reflection occurs, and the higher the glossiness of the surface of the reflective film 310 is, the higher the reflectivity is. Further, the reflective film 310 may use a single-layer structure reflective film 310, a double-layer structure reflective film 310, and a three-layer structure reflective film 310. The single-layer structure reflective film 310, that is, the cross section of the whole film, is uniform, the single-layer structure reflective film 310 has higher density, and a large amount of inorganic additives are added into the single-layer structure reflective film to form an opaque effect, thereby playing a role in surface reflection.

Specifically, the light guide plate 320 is square, and a corner of the light guide plate 320 may be provided with a chamfer to facilitate the installation of the light guide plate 320.
Specifically, the light guide plate 320 is an optical acrylic or PC plate, and a high-tech material with an extremely high refractive index and no light absorption is used to print light guide points on the bottom surface of the optical acrylic plate by using laser engraving, V-shaped cross grid engraving, UV screen printing and other techniques; and the light emitted from the lamp is absorbed by the optical acrylic plate and stays on the surface of the optical acrylic plate, when the light is emitted to each light guide point, the reflected light is diffused to each angle, and then the reflection condition is destroyed and emitted from the front surface of the light guide plate 320. The light guide plate 320 can uniformly emit light by various light guide points having different densities and sizes. That is, the light guide plate 320 is a high-tech product for converting a linear light source into a surface light source, the light guide plate 320 uses optical acrylic (PMMA)/PC as a base material, and uses the backlight module technology of an LCD display screen and a notebook computer to transmit high light conductivity of a light guide point, and calculates the light guide point, so that the light guide plate 320 refracts light into the surface light source until the light is in a uniform light state, and the light guide plate 320 has the advantages of ultra-thin, ultra-bright, uniform light guide, energy saving, environmental protection, no dark area, durability, difficult yellowing, simple and rapid installation and maintenance, and the like.

The diffusion film 330 mainly plays a role in correcting diffusion angles in the structure of the light-transmitting component 300, so that the light radiation area is increased, and the brightness is reduced.

Further, the diffusion film 330 mainly includes a three-layer structure, i.e., an anti-scratch layer, a transparent PET substrate layer, and a diffusion layer. Light is incident from the lowest scratch-resistant layer, penetrates through the highly transparent PET substrate, and is scattered by diffusion particles dispersed in the diffusion coating to form a uniform surface light source. Most of the diffusion particles are spherical, the function of the diffusion particles is similar to that of a convex lens, and light rays are focused into a certain emergent angle when passing through the particles, so that the function of enhancing the emergent light brightness is achieved. In addition, the diffusion particles with different particle sizes in the diffusion layer also ensure that light cannot directly penetrate out of the diffusion film 330, thereby achieving the atomization effect.
