It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a diffuser plate 100 according to an embodiment of the present invention will now be described. The diffusion plate 100 is provided with light-blocking spots 110 for blocking light from passing through, dense areas 120 formed by densely distributing the light-blocking spots 110, and sparse areas 130 formed by sparsely distributing the light-blocking spots 110. Specifically, the sparse area 130 is provided with a density of the light-blocking points 110 that is less than the density of the light-blocking points 110 provided by the dense area 120. The dense region 120 and the sparse region 130 are combined into a light transmission region, and a light beam irradiated through the light transmission region can form a pattern having a difference in brightness.
In use, the diffuser plate 100 is installed in a corresponding lamp or lighting device. When a light beam emitted from a light source assembly 300 in a lamp or a lighting device passes through the diffusion plate 100, light rays irradiated onto the light blocking point 110 are blocked and cannot be irradiated out of the lamp or the lighting device, and light rays irradiated onto other positions of the diffusion plate 100 can be smoothly emitted out through the light emitting surface, so that light rays in an area corresponding to the light blocking point 110 in the light beam emitted from the diffusion plate 100 are lost, and further, the light emitting amount of the corresponding area is reduced. Moreover, since the density of the light blocking dots 110 disposed in the sparse region 130 is low, and the density of the light blocking dots 110 disposed in the dense region 120 is high, the light output amount of the sparse region 130 is greater than that of the dense region 120, so that the light emitted through the diffusion plate 100 forms a pattern with a certain light-dark difference. The patterns with certain light and shade difference can show light and shade effects when being irradiated on the object, so that the stereoscopic impression of the object is highlighted, or light ray images with the light and shade effects are projected on the object, and the indoor lighting effect is increased.
It should be noted that the sparse region 130 and the dense region 120 are relative, a region where the light-blocking spots 110 are sparse (corresponding to a region with a large light-emitting amount) is the sparse region 130, a region where the light-blocking spots 110 are dense (corresponding to a region with a small light-emitting amount) is the dense region 120, and there is no clear boundary between the two regions. The arrangement of the light blocking points 110 on the diffusion plate 100 is not limited to the arrangement shown in fig. 1, and fig. 1 is only an example for easy understanding, and the arrangement of the light blocking points 110 on the diffusion plate 100 can be flexibly set according to the visual effect desired to be produced.

During manufacturing, the light beam effect emitted by the diffuser plate 100 can be adjusted by adjusting the arrangement of the light-blocking points 110 on the diffuser plate 100, i.e., the density of the light-blocking points 110 in different areas. The lamp or the light-emitting device made of the diffusion plate 100 provided by the embodiment can show the visual effect of a 3D pattern, realize the effect of decorating and beautifying the environment, can be applied to indoor decoration places such as hotels, stores and the like, provide personalized customization service for customers, enable the product application to adapt to diversified market demands, and further improve market competitiveness.
In order to meet the requirement of diversified lighting effects, please refer to fig. 1, a plurality of dense areas 120 and sparse areas 130 are respectively arranged, a plurality of dense areas 120 and a plurality of sparse areas 130 are combined into one or a plurality of light transmission areas, and the pattern can be adjusted by adjusting the number, shape and arrangement of the light spots 110 in each light transmission area, so as to meet the lighting effect requirements of different use environments. Specifically, each light-transmitting area may be provided with one dense area 120 and one sparse area 130, one dense area 120 and a plurality of sparse areas 130, a plurality of dense areas 120 and one sparse area 130, or a plurality of dense areas 120 and a plurality of sparse areas 130.
The number, shape and arrangement of the dense areas 120 and the sparse areas 130 in different second light transmission areas on the same diffusion plate 100 may be the same or different, and the number, shape and arrangement of the light blocking spots 110 in different dense areas 120 or sparse areas 130 in the same light transmission area may be the same or different, specifically set according to the light emitting effect.
The light-blocking points 110 can be opaque dots printed on the diffuser plate 100 to improve the visual effect of the light emitted from the lamp, and the light flux is not substantially lost in the case of white light. The shape of the light blocking point 110 is not limited to a circle, a rectangle, an irregular arc, any polygon or other shapes, and can be specifically set according to the light emitting effect. The light blocking points 110 on the same diffusion plate 100 may have the same shape, or different shapes, or partially the same or different shapes, and the density and density pitches are arranged according to actual requirements, and the pitch ranges are: 0< x < length of light emitting surface, 0< y < width of light emitting surface.
