Examples:
as shown in fig. 1, a glass diffuser plate with a side-entry light source curved glass backing plate, comprising: the glass backboard 1 and the reflective ink coating 11 printed on the glass backboard 1, wherein the glass substrate 2 is arranged on one side of the glass backboard 1, which is bent inwards, the diffusion coating 21 is arranged on one side of the glass substrate 2, which is far away from the glass backboard 1, and the effect of further homogenizing light is achieved through the diffusion coating 21. The glass substrate 2 is provided with reflective dots 3 towards the glass back plate 1 side. The glass substrate 2 and the diffusion coating 21 form a diffusion plate.
The glass backboard 1 is in a bent shape, one end of the glass backboard 1 is connected with the glass substrate 2, the other end of the glass backboard 1 and the glass substrate 2 are arranged at intervals, and the LED lamp strips 4 are arranged at intervals between the glass backboard 1 and the glass substrate 2.
In this embodiment, the bending curvature of the glass back plate 1 gradually increases in a direction away from the LED light bar 4, so as to improve the reflection effect on the side away from the LED light. The light on the side far away from the LED light bar 4 is weaker, and the reflection light can be more concentrated due to the large bending curvature of the glass backboard 1. Meanwhile, the density of the reflecting dots 3 of the light-emitting surface of the glass substrate 2 at one side far away from the LED light bar 4 is minimum, the light transmittance is highest, correspondingly, the light is stronger at one side close to the LED light bar 4, the bending curvature of the back plate is smaller, the reflected light is more divergent, meanwhile, the density of the reflecting dots 3 at the corresponding position of the diffusion plate is larger, the reflected light is more, after the light is reflected back into the backlight module, the light is more uniform after diffuse reflection by the reflecting coating, and as the LED light bar 4 is arranged at the side, poor pictures such as lamp shadows and the like can not occur on the light-emitting surface of the diffusion plate, and the diffusion ink of the light-emitting surface plays roles of further homogenizing and shielding the reflecting dots 3. In this embodiment, the distance between the glass back plate 1 and the glass substrate 2 can be controlled within 20mm, and the optical uniformity of the diffusion plate can reach more than 90%.
In this embodiment, the density of the reflective dots 3 gradually becomes thinner in a direction away from the LED light bar 4, and the dot diameter of the reflective dots 3 is 0.2-0.4mm, and the density range of the reflective dots 3 is as follows: 5-45%, and most of light rays of the LED lamp, which are directly irradiated on the glass light incident surface, are reflected back into the backlight module to further perform the function of uniform light. The method can lead the optical uniformity of the glass diffusion plate to reach more than 90 percent.
Wherein the thickness of the reflective ink is 50-60 mu m, the reflectivity is more than 95%, and the surface roughness Ra=10-15 mu m can play a role of multi-angle scattering.
Through setting up LED lamp strip 4 in backlight unit side, collocation diffuser plate is last the reflection site 3 of density gradual change and the glass backplate 1 of crooked camber gradual change simultaneously, evenly disperses the light source that LED lamp strip 4 sent out of side income to the play plain noodles of glass substrate 2, reaches the reduction backlight unit thickness and ensures simultaneously that backlight unit possesses good optics and picture effect, also makes backlight unit's appearance structure more novel, more pleasing to the eye.
To sum up: by arranging the LED lamp strips 4 on the side edge of the diffusion plate, the overall thickness of the backlight module can be reduced; through the inward bending design of the glass backboard 1, the bending curvature is gradually increased from one side far away from the LED light bar 4, the purpose of concentrating the light reflected from one side far away from the LED light bar 4 is achieved, the purpose of preliminary light balancing is achieved, meanwhile, the inward bending design of the glass backboard 1 is novel in structure, attractive in appearance and capable of enhancing ornamental value; the purpose of further homogenizing light is achieved by designing the reflection net points 3 with gradually changed density on the light incidence surface of the glass diffusion plate, and the light uniformity and the picture effect of the light emergence surface of the diffusion plate are further improved.
