Abstract
The utility model proposes a kind of anti-dazzle light guide plates, include by optical-grade transparent plate of material as the scattering surface as outgoing plane below the substrate of the plane of incidence and the substrate, the scattering surface is made of several prism block close-packed arrays, and several prism blocks are the identical rectangular frustum structure in bottom surface；The upper surface of prism block is systematicness relief, and adjacent prism block upper surface forms the wavy surface of discontinuous periodic relief.The utility model reduces the probability of light scattering, enhances spotlight effect and reduces dazzle amount, human eye is made to be in comfort conditions.
Description
Technical field
The present invention relates to optics consumptive material more particularly to a kind of anti-dazzle light guide plates.
Background technology
Original LED soft light light guide plate is the milky white acrylic material of PMMC frosteds, although the light extraction of LED lamp is made to become
It is soft, but light extraction efficiency and brightness become very low, brighten by lamps and lanterns if to increase lamp power, light guide plate can become to pierce very much
Eye dazzles the eyes sense very strong, influences the experience of user.
Invention content
The present invention proposes a kind of anti-dazzle light guide plate, solves the problems of the prior art.
The technical proposal of the invention is realized in this way：
Anti-dazzle light guide plate includes by optical-grade transparent plate of material as the work below the substrate of the plane of incidence and the substrate
For the scattering surface of outgoing plane, the scattering surface is made of several prism block close-packed arrays, and several prism blocks are that bottom surface is identical
Rectangular frustum structure；The upper surface of prism block is systematicness relief, and adjacent prism block upper surface forms the discontinuous period
The wavy surface of fluctuating.
As the preferred embodiment of the present invention, the substrate incident face paste has abrasive segments.
As the preferred embodiment of the present invention, transparent colloidal layer is equipped between the scattering surface and the substrate.
As the preferred embodiment of the present invention, reflecting coating is equipped on the inside of the prism block side.
As the preferred embodiment of the present invention, four sides of the prism block and bottom surface shape are angled α, wherein scattering surface
Refractive index is n, wherein α≤5 2≤n/sin.
Advantageous effect
The present invention proposes a kind of anti-dazzle light guide plate, include by optical-grade transparent plate of material as the plane of incidence substrate and
The scattering surface as outgoing plane below the substrate, the scattering surface are made of several prism block close-packed arrays, several prisms
Block is the identical rectangular frustum structure in bottom surface；The upper surface of prism block is systematicness relief, adjacent prism block upper table
Face forms the wavy surface of discontinuous periodic relief.The present invention reduces the probability of light scattering, enhances spotlight effect and reduces dazzle
Amount, makes human eye be in comfort conditions.
Description of the drawings
