Layer, passed through in medium that can be different with refractive index so that light is there is a phenomenon where many refractions, reflection and scatters, and can correct light
Into uniform area light source to reach the effect of optics diffusion, the effect for correcting diffusion angle, meeting are primarily served in back light source structure
Increase light radiation area, but be reduction of the luminous intensity of unit area, that is, lower briliancy, illuminating source is spread through diffusion material
Hou, area bigger can be become, the uniformity is preferable, 2 secondary light sources of chroma stability, while is also required to use on computer casing
Optical diffusion, so as to improve the practicality of computer casing.
But existing optical diffusion is in use there is some shortcomings, for the light in diffusion barrier
Diffusivity is not comprehensive enough, there is a phenomenon where printing opacity dead angle, so as to reduce the light transmittance of diffusion barrier.
The content of the invention

As further describing for above-mentioned technical proposal：
The diffusion particle is in dislocation type structure, and the outer surface of the light guide stream convex block is arc smooth structure.
In the utility model, pass through the first diffusion particle layer of setting, the second diffusion particle layer and the 3rd diffusion grain first
The thickness size of sublayer is different, and multi-level diffusion effect can be played to the route of transmission of incident ray, so that
The transmitance of light is more efficient, and secondly by the light guide stream convex block of setting, when light is radiated on diffusion particle, arc is put down
Sliding light guide stream convex block can play refraction effect to light so that the diffusion irradiated area bigger of light, avoids reflecting
The phenomenon at dead angle, enhances the light transmittance of diffusion barrier, on the other hand the diffusion barrier overall construction design advantages of simple, employs more
The assembled arrangement of level, on the premise of high transparency is ensured, also ensure that the safety in utilization of diffusion barrier.
