Description
Technical field
This utility model relates to a kind of two sides and has the diffuser plate of prism microstructure.
Background technology
Traditional diffuser plate is mainly and adds chemical particle in diffuser plate base material as scattering particles, makes light constantly reflect in the medium that two refractive indexs are different through scattering layer, reflect and scattering, produces, with this, the effect that optics spreads.But this mode, by being inevitably present the diffusion particle absorption to light, cause the efficiency of light energy utilization low.
Current light fixture uses LED or the point/line source of other high brightness, for reducing light source dazzle or improving light source comfort level visually, diffuser plate is generally used point/line source to be diffused as the area source of brightness uniformity, and the index weighing diffusion effect is mist degree and light transmittance, both are the highest more good, but these two kinds of optical indexes are contradiction in existing technology.Conventional diffusion plate is addition diffusant in the base materials such as transparent PMMA, PC, PS, PP, by the micro structure of diffusant and substrate surface to the refraction of light, reflect, scatter and reach light diffusion effect, general diffusant is the low transparent roughened appearance of white, the diffusant that diffuser plate that mist degree is the highest is to be added is the most or micro structure is the most tiny, density is the highest, owing to the diffusion particle of diffusant also exists the effect blocked and diffusant and micro structure to light, light refraction repeatedly, scattering are caused the loss of light, so the highest its light transmittance of diffuser plate of mist degree is the lowest.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of two sides has the diffuser plate of prism microstructure.
The technical solution adopted in the utility model is:
A kind of two sides has the diffuser plate of prism microstructure, it includes that diffusion substrate, described diffusion substrate upper surface are exiting surface, and the exiting surface of diffusion substrate is provided with the first micro-prism structure, the lower surface of diffusion substrate is reflecting surface, and the reflecting surface of diffusion substrate is provided with the second micro-prism structure；Described first micro-prism structure includes more than two the first prism bar be arrangeding in parallel, the cross section of described first prism bar is isosceles triangle, the angle of the vertex angle theta of the first prism bar is 110-120 degree, the depth H of the first prism bar is 80-90 μm, described second micro-prism structure includes more than two the second prism bar be arrangeding in parallel, the cross section of described second prism bar is isosceles triangle, second Pedicellus et Pericarpium Trapae mirror angle a is 90-110 degree, second prism bar height h is 70-80 μm, and described first micro-prism structure is the most vertical with the second micro-prism structure.
Described first micro-prism structure is one-body molded with diffusion substrate.
The thickness of described diffusion substrate is 0.6-0.9mm.
Described diffusion substrate is made up of lucite, polycarbonate, polystyrene or polyacrylic transparent plastic.
Described first micro-prism structure and the second micro-prism structure all use roll-in method one-shot forming.
This utility model uses above technical scheme, the upper and lower surface of diffusion substrate is provided with orthogonal first micro-Pedicellus et Pericarpium Trapae mirror structure and the second micro-prism structure, and first micro-Pedicellus et Pericarpium Trapae mirror structure and the second micro-prism structure all use micro structure roller one-shot forming, light diffusing sheet is made to have high permeability, by changing the shape of first micro-Pedicellus et Pericarpium Trapae mirror structure and the second micro-prism structure and different arrangement, diffusion angle, the space of light field and Energy distribution can be adjusted, it is achieved the uniformity and the impact of light transmittance on light diffusing sheet.Diffuser plate of the present utility model can reflect by light in use, reflect, the mode that scatters causes vision atomization or light source image multilayer imaging to reach the function of diffusion.Make to use panel of the present utility model to obtain numerous light source focus because of the most vertical micro-structure, thus diffusion is extremely large.
