Abstract
The invention discloses a multi-sawtooth light diffusion plate. The multi-sawtooth light diffusion plate comprises a diffusion plate body, diffusion sawteeth, a double reflecting device and nano titanium particles. The double reflecting device comprises reflecting protrusions and reflecting grooves; the diffusion plate body, the diffusion sawteeth and the double reflecting device are all made of transparent materials; the diffusion sawteeth are of a structure of triangular prisms and are arranged on the top surface and the bottom surface of the diffusion plate body; the nano titanium particles are uniformly arranged inside the diffusion plate body; the reflecting protrusions and the reflecting grooves are arranged at the tops of the diffusion sawteeth. Therefore, the multi-sawtooth light diffusion plate reflects and refracts light through multiple sawteeth, thereby improving the light utilization rate and enabling light diffusion to be more uniform.
Description
Technical field
The present invention relates to field of illuminating device, particularly relate to a kind of many sawtooth light diffusing sheet.
Background technology
Light diffusing sheet is by the means of chemistry or physics, while utilizing light to be expert to run in track the different medium of two refractive indexes (density), reflects, the device of the physics imagination of reflection and scattering.
But the light diffusing sheet on market is not out of this world now, and they are lower to the utilization factor of light, and a large amount of light can be wasted, and through diffusion after light inhomogeneous, more dazzling, it is not convenient to use, so the light diffusing sheet that people need to meet the demands more.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of many sawtooth light diffusing sheet, has that reliability is high, effective, utilization factor advantages of higher, simultaneously the application of lighting device and universal on have market outlook widely.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of many sawtooth light diffusing sheet is provided, it comprises: diffuser plate body, diffusion sawtooth, secondary turn back device and nano-titanium grain, the described secondary device of turning back comprises turn back projection and the groove of turning back, described diffuser plate body, described diffusion sawtooth and the described secondary device of turning back is made by transparent material, described diffusion sawtooth is triangular prism structure, described diffusion sawtooth is arranged on the end face and bottom surface of described diffuser plate body, described nano-titanium grain is arranged in described diffuser plate body uniformly, described turn back projection and described in the groove of turning back be arranged at the top of described diffusion sawtooth.
In a preferred embodiment of the present invention, the angle between the relative side of adjacent two described diffusion sawtooth is less than 35 °.
In a preferred embodiment of the present invention, described transparent material comprises acrylic, crystal, glass or resin.
In a preferred embodiment of the present invention, described in turn back projection with described in the groove of turning back be 1-3:1 and be spaced.
In a preferred embodiment of the present invention, the height of described diffusion sawtooth is 30um-60um.
The invention has the beneficial effects as follows: by multiple sawtooth, light reflected and reflect, having improved the utilization factor to light, and can allow the more even of divergence of beam.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of a kind of many sawtooth light diffusing sheet one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, diffuser plate body, and 2, diffusion sawtooth, 3, the projection of turning back,
4, the groove of turning back, 5, nano-titanium grain.
Embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of many sawtooth light diffusing sheet, it comprises: diffuser plate body 1, diffusion sawtooth 2, secondary turn back device and nano-titanium grain 5, the described secondary device of turning back comprises turn back projection 3 and the groove 4 of turning back, described diffuser plate body 1, described diffusion sawtooth 2 and the described secondary device of turning back is made by transparent material, described diffusion sawtooth 2 is triangular prism structure, described diffusion sawtooth 2 is arranged on the end face and bottom surface of described diffuser plate body 1, described nano-titanium grain 5 is arranged in described diffuser plate body 1 uniformly, described turn back projection 3 and described in the groove 4 of turning back be arranged at the top of described diffusion sawtooth 2.
The tangent plane of described diffusion sawtooth 2 not only can adopt triangular structure, but also can adopt trapezoidal, semicircle or other irregular shapes, after light enters into diffuser plate body 1 and goes, can reflect and reflect by each face of described nano-titanium grain 5 and described diffusion sawtooth 2, light after reflection or refraction can be again through the described secondary device of turning back, after reflection and refraction repeatedly, can allow light become more soft, not dazzling, allow light spread uniformly, but also can utilize fully most or all light of injecting, improve the utilization factor of light.
Angle between the relative side of adjacent two described diffusion sawtooth 2 is less than 35 °, if the angle of two adjacent sides is excessive, light is in reflection or refraction, have some or a large amount of light is ingested in air, reduce catoptrical amount, and described many sawtooth of one light diffusing sheet can prevent that light runs off, allow light carry out reflection and refraction repeatedly in described diffusion sawtooth 2 and described secondary are turned back device, improve the utilization factor to light.
Described transparent material comprises acrylic, crystal, glass or resin, and the transparency of these materials is higher, can facilitate entering and catadioptric of light.
Described turn back projection 3 with described in the groove 4 of turning back be 1-3:1 and be spaced, can utilize so different shapes to turn back to light, and can prevent the situations such as the overlapping or light loss of the mutually produced simultaneously light of shape, make light more even.
The height of described diffusion sawtooth 2 is 30-60um, can reduce like this thickness of diffuser plate, can effectively reduce the volume of diffuser plate, reduces production cost, easy to use.
The beneficial effect of a kind of many sawtooth light diffusing sheet of the present invention is: by multiple sawtooth, light reflected and reflect, having improved the utilization factor to light, and can allow the more even of divergence of beam.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
