Abstract
The invention discloses a multifunctional multi-layer diffusion plate, which comprises a first diffusion plate, a second diffusion plate, a third diffusion plate, diffusion grooves and diffusion titanium particles, wherein the first diffusion plate and the third diffusion plate are respectively connected with the top surface and the bottom surface of the second diffusion plate, each diffusion groove is formed in the second diffusion plate, and is of a pyramid-shaped structure, and the diffusion titanium particles are respectively arranged in the first diffusion plate and the second diffusion plate. By adopting the method, the multifunctional multi-layer diffusion plate has the advantages that by realizing the multi-layer diffusion overlapping effect, the utilization rate of light rays is improved, the emitting of the light rays is more uniform, and the glare is avoided.
Description
Technical field
The present invention relates to field of illuminating device, particularly relate to a kind of Multifunctional multilayer diffuser plate.
Background technology
Diffuser plate is by chemistry or the means of physics, during the medium utilizing light to be expert to run in track two refractive indexes different, reflects, reflects the device imagined with the physics of scattering.
But the existing utilization factor of light diffusing sheet to light is commercially lower, and a large amount of light can be wasted, and light after diffusion is uneven, more dazzling, and it is not convenient to use, so people need the light diffusing sheet more met the demands.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of Multi-functional V-shaped groove diffuser plate, has that reliability is high, effective, utilization factor advantages of higher, simultaneously lighting device application 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 Multifunctional multilayer diffuser plate is provided, it comprises: the first diffuser plate, the second diffuser plate, the 3rd diffuser plate, spreading grooves and diffuse titanium grain, described first diffuser plate is connected with bottom surface with the end face of described second diffuser plate respectively with described 3rd diffuser plate, described spreading grooves is provided with in described second diffuser plate, described spreading grooves have employed pyramid structure, and described diffuse titanium grain is arranged in described first diffuser plate and described 3rd diffuser plate respectively.
In a preferred embodiment of the present invention, between adjacent two described spreading grooves, leave gap.
In a preferred embodiment of the present invention, the described diffuse titanium grain in described first diffuser plate is in same level.
In a preferred embodiment of the present invention, the described diffuse titanium grain in described 3rd diffuser plate is in same level.
The invention has the beneficial effects as follows: by the effect of multilayer diffusion superposition, improve the utilization factor to light, and allow the more even, not dazzling of divergence of beam.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment 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, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of Multifunctional multilayer diffuser plate one of the present invention preferred embodiment;

Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of Multifunctional multilayer diffuser plate, it comprises: the first diffuser plate 1, second diffuser plate 2, the 3rd diffuser plate 3, spreading grooves 4 and diffuse titanium grain 5, described first diffuser plate 1 is connected with bottom surface with the end face of described second diffuser plate 2 respectively with described 3rd diffuser plate 3, described spreading grooves 4 is provided with in described second diffuser plate 2, described spreading grooves 4 have employed pyramid structure, and described diffuse titanium grain 5 is arranged in described first diffuser plate 1 and described 3rd diffuser plate 3 respectively.
By the first diffuser plate 1, described second diffuser plate 2 and described 3rd diffuser plate 3, allow the scattered power raising gradually of light, line of giving out light is more evenly soft, not dazzling
Leave gap between adjacent two described spreading grooves 4, a large amount of the flocking together of light can be prevented like this, improve the utilization factor of light.
Described diffuse titanium grain 5 in described first diffuser plate 1 is in same level.
Described diffuse titanium grain 5 in described 3rd diffuser plate 3 is in same level.
The beneficial effect of Multifunctional multilayer diffuser plate of the present invention is: by the effect of multilayer diffusion superposition, improve the utilization factor to light, and allows the more even, not dazzling of divergence of beam.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; 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.
