Description

Technical Field

[0001] This utility model relates to the field of diffuser plate technology, and in particular to a novel blue light blocking foam board. Background Technology

[0002] Light diffusers utilize the physical phenomena of refraction, reflection, and scattering that occur when light encounters two media with different refractive indices during its journey, through chemical or physical means. By artificially adjusting the light through diffusers, the light can undergo refraction, reflection, and scattering in different directions, thereby altering the path of the light. Foamed diffusers, on the other hand, increase the degree of refraction of the diffuser by injecting gas into the polymer during the diffuser molding process, causing the gas to form dense bubbles within the polymer.

[0003] A search revealed that Chinese utility model patent application CN202320108419.3 discloses an injection-molded foamed miniLED diffuser plate, comprising: a light-incoming layer including several microstructures, each microstructure used for initial light dispersion; a light-emitting layer with a frosted texture; and a diffuser layer disposed between the light-incoming layer and the light-emitting layer, the diffuser layer containing a light-diffusing agent and uniformly distributed air bubbles. This application has the effect of improving the uniformity of light diffusion.

[0004] For example, Chinese utility model patent application CN202121799689.0 discloses a foamed light diffuser structure, including a foamed layer and a composite layer. Both sides of the foamed layer are covered by the composite layer. One surface of the composite layer has strip-shaped protrusions, and the other surface has an orange peel texture or a frosted texture. The protective film covering the surface of the composite layer with the strip-shaped protrusions is made of bubble wrap, and the protective film covering the surface of the other composite layer is made of release film. The foamed light diffuser structure of this application can achieve the following functions: light is refracted when passing through the surface of the strip-shaped protrusions, thereby changing the direction of light travel and increasing the amount of light within a certain viewing angle, thus improving the light-gathering effect and achieving the purpose of increasing the brightness when viewed from the front of the display device, and also serving as a privacy screen.

[0005] While the existing foam diffusion technology can meet basic usage requirements, it cannot absorb or reduce the harmful blue light emitted by LED lights, which can easily cause eye fatigue. Furthermore, it has low compressive strength and is prone to damage during use, making it not durable enough. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a new type of anti-blue light foam board in view of the above-mentioned defects of the prior art. By adding an anti-blue light coating, the harmful blue light of LED lights is absorbed, relieving eye fatigue. By setting up anti-pressure and anti-damage mechanisms that cooperate with the first flange and the second flange respectively, the compressive strength of the foam diffuser board body is enhanced, making it less prone to damage and cracking during use and more durable.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0010] Preferably, the pressure-resistant and damage-preventing part is composed of a pressure-resistant groove, a second reinforcing plate, and a pressure-resistant plate, wherein the pressure-resistant groove is formed on the outer side of the foamed diffusion plate body.

[0011] Preferably, the inner wall of the pressure-resistant groove is equipped with pressure-resistant plates at equal intervals to improve the pressure resistance of the foamed diffusion plate body, and the surface of the pressure-resistant plates is equipped with a second reinforcing plate to further improve the pressure resistance of the foamed diffusion plate body.

[0021] like Figure 1-3 As shown, the novel anti-blue light foam board includes a foam diffuser body 1. The surface of the foam diffuser body 1 is coated with an anti-blue light coating 3. An anti-pressure and anti-damage mechanism 2 is sleeved on the outer side of the foam diffuser body 1. A first flange 101 and a second flange 102 are provided on the outer side of the anti-pressure and anti-damage mechanism 2. A first connecting plate 103 and a second connecting plate 104 are respectively installed on the first flange 101 and the second flange 102. A fastening stud 105 is threadedly connected to the second connecting plate 104. The fastening stud 105 passes through the second connecting plate 104 and the first connecting plate 103 in sequence and extends to the bottom of the first connecting plate 103. A nut body 106 is threadedly sleeved on the surface of the fastening stud 105. The surface of the nut body 106 abuts against the surface of the first connecting plate 103. Understandably, the thickness of the anti-blue light coating 3 is 1μm to 20μm. The anti-blue light coating 3 can be applied to the foamed diffuser plate body 1 by anti-blue light coating liquid, first thermosetting and leveling, and then bonding together after UV curing. It has uniform color and good adhesion. The anti-blue light coating liquid includes nanocrystals, UV curing resin, photoinitiator, other additives and solvents. The nanocrystals are one or a combination of C quantum dots, Si quantum dots, ZnO, SiO2, CdS, PbS, CdSexTe1-x, CuInS2, ZnCdS / ZnS. When the light emitted by the LED light source passes through the anti-blue light coating 3, it can effectively absorb blue light in the 420nm-460nm wavelength band.

[0022] Specifically, the pressure-resistant and damage-preventing mechanism 2 includes a first reinforcing plate 201, a plate body 202, and a pressure-resistant and damage-preventing part 203.

The pressure-resistant and damage-preventing part 203 is composed of a pressure-resistant groove 2031, a second reinforcing plate 2032, and a pressure-resistant plate 2033. The pressure-resistant groove 2031 is opened on the outside of the foamed diffusion plate body 1, and the inner wall of the pressure-resistant groove 2031 is equipped with equally spaced grooves for improving the pressure resistance of the foamed diffusion plate body. The compression-resistant plate 2033 enhances the compressive strength of the body 1. A second reinforcing plate 2032 is installed on the surface of the compression-resistant plate 2033 to further improve the compressive strength of the foamed diffusion plate body 1. The surfaces of the second reinforcing plates 2032 are fixed to the inner walls of the compression-resistant groove 2031. The compression-resistant groove 2031 is equipped with equally spaced plates 202. A first reinforcing plate 201 is installed between the plates 202 to enhance the overall strength of the foamed diffusion plate body 1. Understandably, the combined action of the inner plate 202 of the compression groove 2031 and the first reinforcing plate 201 enhances the compressive strength of the foamed diffusion board body 1. The action of the compression plate 2033 inside the compression groove 2031 greatly improves the compressive strength of the foamed diffusion board body 1. The action of the second reinforcing plate 2032 further enhances the overall strength of the foamed diffusion board body 1, making the second reinforcing plate 2032 less prone to damage and cracking during use, thus making the foamed board more durable and achieving the function of improving the compressive strength of the foamed board.
