Abstract
The utility model proposes a kind of 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 includes alternately arranged first prism bar and the second prism bar, and the substrate incident face paste has abrasive segments.The utility model passes through optical design, frosting is processed into the prism bar with soft light effect, to improve light efficiency, and increase single side frosted abblendbar light guide sheet, it realizes abblendbar function, is designed by double layer light-guiding, brightness is not only greatly improved in the case where not increasing power, meet not dazzling, dazzle-free requirement simultaneously.
Description
Technical field
The present invention relates to optics consumptive material more particularly to a kind of 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 light guide plate, solves the problems of the prior art.
The technical proposal of the invention is realized in this way：
Light guide plate includes being projected as the conduct below the substrate of the plane of incidence and the substrate by optical-grade transparent plate of material
The scattering surface in face, the scattering surface include alternately arranged first prism bar and the second prism bar, and the substrate incident face paste has
Abrasive segments.
As the preferred embodiment of the present invention, the section of first prism bar and second prism bar is all that base angle is
45 ° of isosceles trapezoid.
As the preferred embodiment of the present invention, the bottom edge length in first prism bar section is A, and first prism bar is cut
The height in face is B, and the bottom edge length in second prism bar section is C, and the height in second prism bar section is D, wherein
1.5≤A/C≤2,1.7≤B/D≤2.8.
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, the bottom edge length of several first prism bars gradually becomes from centre to both sides
It is short.
As the preferred embodiment of the present invention, the bottom edge length of several second prism bars gradually becomes from centre to both sides
It is long.
Advantageous effect
The present invention proposes a kind of light guide plate, includes the substrate by optical-grade transparent plate of material as the plane of incidence and the base
The scattering surface as outgoing plane below plate, the scattering surface include alternately arranged first prism bar and the second prism bar, institute
Stating substrate incident face paste has abrasive segments.The present invention is processed into the prism bar with soft light effect by optical design, by frosting,
To improve light efficiency, and increase single side frosted abblendbar light guide sheet, realizes abblendbar function, designed by double layer light-guiding, no
Brightness is only greatly improved in the case where not increasing power, while meeting not dazzling, dazzle-free requirement.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without having to pay creative labor, may be used also for those of ordinary skill in the art
With obtain other attached drawings according to these attached drawings.
Fig. 1 is the main structure diagram of the present invention.
Substrate 1, the first prism bar 2, the second prism bar 3.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
Light guide plate as shown in Figure 1 includes 1 lower section of substrate 1 and substrate by optical-grade transparent plate of material as the plane of incidence
The scattering surface as outgoing plane, scattering surface includes 2 and second prism bar 3 of alternately arranged first prism bar, 1 plane of incidence of substrate
Post abrasive segments.
The section of first prism bar 2 and the second prism bar 3 is all the isosceles trapezoid that base angle is 45 °.
The bottom edge length in the first prism bar section is A, and the height in the first prism bar section is B, 3 section of the second prism bar
Bottom edge length is C, and the height in 3 section of the second prism bar is D, wherein 1.5≤A/C≤2,1.7≤B/D≤2.8.
Transparent colloidal layer is equipped between scattering surface and the substrate 1.
The bottom edge length of several first prism bars 2 gradually shortens from centre to both sides.
The bottom edge length of several second prism bars 3 is progressively longer from centre to both sides.
The quantity of the first prism bar 2 and the second prism bar 3 at least has 2 respectively in scattering surface.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
