Description

A kind of LED panel lamp diffuser plate

Technical field

It the utility model is related to LED lamp materials processing technology field, and in particular to a kind of LED panel lamp diffuser plate.

Background technology

Diffuser plate is by means chemically or physically, and being expert at using sound, light in track, it is different to run into two refractive index Medium when, occur refraction, reflection with scattering physics imagine, by adding nothing in the Substrate basis such as PMMA, PC, PS, PP Machine or the array of organic light diffusing agent or the micro-feature structure for passing through substrate surface arrange artificial adjustment sound, light, make sound, The refraction, reflection and scattering of different directions occur for light, so that the route of travel of change sound, light, realizes that incident sound, light are abundant Dissipate the effect that color produces diffusion with this.

LED panel lamp diffuser plate provides a uniform area source for products such as LED panel lamps, general traditional diffuser plate It is mainly PMMA mainly in diffusion substrates, in PC, PS, certain inorganic chemical particle is added, the drawback is that to light absorption Rate is high, and light penetration is low.

Utility model content

The purpose of this utility model is that the defects of being directed to the prior art and deficiency, there is provided a kind of simple in structure, design is closed Reason, LED panel lamp diffuser plate easy to use.

To achieve the above object, the technical solution adopted in the utility model is：It includes lower base layer of resin, the first micro-structure Diffusion layer, the first spherical diffusant, the first resin grid, the second micro-structure diffusion layer, the second spherical diffusant, the second resin web Lattice, the 3rd micro-structure diffusion layer, the 3rd spherical diffusant, upper base layer of resin；The upper surface of the lower base layer of resin is set successively The first micro-structure diffusion layer, the first resin grid, the second micro-structure diffusion layer, the second resin grid, the 3rd micro-structure is equipped with to expand Dissipate layer and upper base layer of resin；In the first micro-structure diffusion layer, the second micro-structure diffusion layer and the 3rd micro-structure diffusion layer Array is provided with the first spherical diffusant, the second spherical diffusant and the 3rd spherical diffusant, and the first spherical diffusant respectively Shifted to install with the 3rd spherical diffusant and the second spherical diffusant.

Preferably, the first spherical diffusant, the second spherical diffusant and the 3rd spherical diffusant use diameter For the spherical diffusant of 4.5~5.5 μm of acrylic acid.

Preferably, the lower base layer of resin and upper base layer of resin are transparent PP resin.

Preferably, the outer surface of the upper base layer of resin is provided with frosted surface layer.

The operation principle of the utility model is：Using multiplelayer microstructure diffusion layer, the mode of microlens array arranges, each A lens all have reflective functions, and the light that light source is sent passes through refraction many times, realize the uniform illumination of greater angle, by It is smaller in each lens, therefore, the light that a certain light source is sent can be not only divided into the light source of numerous identical energy, and And irradiated plane can be divided into the region of numerous equal areas, therefore the luminous flux substantially phase that each region receives Deng so the micro-structure of microlens array form can make the distribution of light more uniformly.

With the above structure, what the utility model produced has the beneficial effect that：A kind of LED panel described in the utility model Lamp diffuser plate, processing technology are convenient, cheap, and in the range of visible ray, light transmittance is up to 92%, good mechanical stability, Impact strength is higher, diffusion light distribution it is uniform, good in optical property, the utility model have it is simple in structure, set rationally, system Make the advantages such as cost is low.
