PS diffusion layers are stacked at PS diffusion plate body light output surfaces, also, uniformly arrangement is inlaid with and can increase in the first PS diffusion layers
First smooth diffusion particle of diffusion effect, uniformly arrangement is inlaid with the second light that can increase diffusion effect in the 2nd PS diffusion layers
Diffusion particle.
As a preferred embodiment, the thickness of the first PS diffusion layers is more than the thickness of the 2nd PS diffusion layers.
As a preferred embodiment, the distribution density of the first smooth diffusion particle is close less than the distribution of the second smooth diffusion particle
Degree, and the first smooth diffusion particle grain size is more than the grain size of the second smooth diffusion particle.
As a preferred embodiment, PS, which spreads uniformly to arrange in plate body, is inlaid with filter blue light particle.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology
Known to scheme：
One, by using PS materials, PS materials electrical insulating property (especially high-frequency insulation) is excellent, water white transparency, light transmittance
More preferably, it is only second to organic glass, and coloring, water resistance, chemical stability are good, then coordinated using three-in-one combination
And the first smooth diffusion particle and the second smooth diffusion particle are set so that light gradually uniformly can fully be spread, and light is significantly increased
Utilization rate, the whole injection improved to light and diffusion effect increase brightness, reduce cost, the performance of product is more
Extensively.
Two, it is inlaid with filter blue light particle by spreading uniformly to arrange in plate body in PS, it is harmful for eyes to stop
Blue light (about wavelength 380-450nm), attenuating facilitate the histiocytic free radical activation of human eye, avoid causing retina or water
The meronecrosis and macula area of crystal are degenerated or cataract.
More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail.
Description of the drawings
Fig. 1 is the sectional view of the preferred embodiment of the utility model.
Description of drawing identification：
