Detailed Description

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "including" and "having," and any variations thereof, in the description and claims of this application and the description of the above figures are intended to cover non-exclusive inclusions. The terms "first," "second," and the like in the description and claims of this application or in the above-described drawings are used for distinguishing between different objects and not for describing a particular order.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As shown in fig. 1 and 2, the embodiment of the present application provides a grid 100, where the grid 100 includes a plurality of grids 1 adjacent to each other on the same antiglare surface (not shown), the projected shapes of the grids 1 on the antiglare surface are different from each other, and the grids 1 can mix light beams passing through the antiglare surface together to form a circular light spot.

Therefore, after the light beam passes through the anti-glare surface, the formed light spots do not have a fixed shape after being superimposed, and the light spots are relatively uniform and circular, and as can be seen from fig. 3, compared with fig. 4, the light spots formed by the uniform cellular anti-glare grids in the prior art are polygonal, while the light spots formed by the grids 100 of the present application are more uniform and circular.

Since the grid 1 is used, the grid 1 has a certain height in the projection direction of the antiglare surface, and thus has a certain antiglare effect.

The antiglare surface is the surface on which the light beam is initially incident on the grid 100, i.e. the outer surface of the grid 100 on the side close to the incident light, and the grid 1 encloses the light through holes 11.

It can be understood that, because the projection shapes of the grids 1 on the anti-dazzle surface are different, that is, the shapes of the grids 1 are different, the grids 100 can ensure that the anti-dazzle function is realized, and the light spots formed by mixing the light beams passing through the anti-dazzle surface are uniform and round light spots, so that the grids not only have the anti-dazzle function, but also ensure that the lamp using the grids meets the clear and uniform lighting requirements.

Based on the above-mentioned grid, this application embodiment still provides a lamps and lanterns, wherein, lamps and lanterns include the lamp body, lamps and lanterns still include foretell grid 100, grid 100 set up in the light-emitting end of lamp body is served.

By adopting the grating 100, the light spots irradiated by the lamp are more uniform and are circular, and the lamp has a good anti-dazzle effect.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

Further, in some embodiments of the present application, in order to ensure that each grid 1 can present a circular light spot formed by mixing light beams passing through the antiglare surface together, the arrangement between each grid 1 in the grid 100 is in the form of a tesson polygon structure, and the projection shape of each grid 1 on the antiglare surface is one of the tesson polygons.

It is understood that the projected shape of each grid 1 on the antiglare surface is a Thiessen polygon. Wherein, each Thiessen polygon only contains one discrete point data; the distance from the point in the Thiessen polygon to the corresponding discrete point is the nearest; the distances from the points on the sides of the Thiessen polygon to the discrete points on the two sides are equal; and the shape of each Thiessen polygon is different, so that the shape of each grating is further ensured to be different.

It should be noted that, due to the thieson polygon generation principle, the randomness of the shape of the graph generated by other methods is relatively low, so that the generated light spot effect is not good as the light spot effect generated by the thieson polygon structure, and will not be described in detail here.

Further, in some embodiments of the present application, each of the grids 1 includes at least 3 bars 2, wherein the bars 2 are connected end to end, and the thickness of the bars 2 is less than or equal to 2 mm.

It should be noted that at least 3 grid bars 2 are needed to be surrounded into a shape, namely, the grid 1 with the Thiessen polygonal structure is surrounded, and the grids 1 are closely arranged, two adjacent grids 1 share the same grid bar 2, and the grid bars 2 in the same grid 1 are connected end to end; for example, if the grid 1 includes 3 bars 2, the grid 1 may be formed into a triangle; if the grid 1 comprises 4 bars 2, the grid 1 can be formed into a quadrilateral.

It should also be noted that in order to make the influence of the bars 2 on the light spot smaller, the thickness of the bars 2 should be as thin as possible, so that as little light as possible is absorbed by the upper surface of the bars 2. In this embodiment, the thickness of the lattice bar 2 is less than or equal to 2 mm, so that it can be ensured that the thickness of the lattice bar 2 cannot be too large, and if the thickness is too large, the effect of the final light spot is affected, so in the most preferred embodiment, the thickness of the lattice bar 2 is less than or equal to 1 mm.

It will be appreciated that the formation of a uniform circular spot can be further ensured by the above-described arrangement of the grid 1.

Further, in some embodiments of the present application, in order to further enhance the antiglare effect of the grid, the ratio of the height of the bars 2 to the length of the longest diagonal in the grid 1 is greater than tan10 °.

It should be noted that the present application is mainly intended to satisfy the antiglare angle of more than 10 ° by setting the ratio of the height of the lattice 2 to the length of the longest diagonal line in the grid 1 to be more than tan10 °. Since the glare angle is usually the angle of the height at which the grid blocks the absorbed light from the horizontal, this is mainly aimed at absorbing light at large angles.

In the present embodiment, if the longest diagonal length of the grid 1 is 10 mm, the height of the grid 100, i.e., the height of the grid bars 2, is at least tan10 ° multiplied by 10 mm, so that a better antiglare effect can be achieved.

It will be appreciated that by further limiting the ratio of the height of the bars 2 to the length of the longest diagonal in the grid 1, a better antiglare effect can be achieved.

Further, in some embodiments of the present application, the grid 2 is made of a plastic material.

Specifically, the grid strips 2 are made of plastic materials, so that light beams irradiated on the grid strips can be absorbed while the grid strips are light in weight. Avoiding random reflection of the light beam. The grid bars 2 can also be made of solid metal, preferably aluminum, and a layer of light-absorbing material is coated on the surface of the solid metal to absorb the light beam irradiated thereon and avoid random reflection of the light beam.

The grating 2 made of plastic material not only has light weight, but also can absorb the light beam irradiated on the grating, so as to avoid random reflection of the light beam, and influence the formation of uniform circular light spots.

Further, in some embodiments of the present application, the shape of the antiglare surface is adapted to the appearance shape of the grid 100.

Since the anti-glare surface is the surface of the grid 100 on which the light beam is initially incident, that is, the outer surface of the grid 100 on the side close to the incident light, it is obvious that the shape of the anti-glare surface is adapted to the external shape of the grid 100, and the external shape of the grid 100 may be any shape as the shape of the anti-glare surface, that is, the external shape of the grid 100 may be specifically adjusted according to the shape of the lamp.

By adapting the shape of the antiglare surface to the shape of the appearance of the grid 100, it is further ensured that the spots appear uniformly circular.

Further, in some embodiments of the present application, the antiglare surface has a shape of a circle, a stripe, a square, or a polygon.

Since the shape of the anti-glare surface is adapted to the external shape of the grid, in order to meet the shape of the lamp, the shape of the anti-glare surface is matched according to the shape of the lamp, as shown in fig. 1 and 2, the anti-glare surface and the external shape of the grid 100 are disclosed to be long strips, and a circular, square or polygonal anti-glare surface can be obtained according to the long strip anti-glare surface disclosed in the present application, which is obvious to those skilled in the art.

According to the shape of the lamp, the anti-dazzle surface is synchronously arranged in a circular shape, a long strip shape, a square shape or a polygonal shape, so that the formation of circular uniform light spots can be further ensured.

Further, in other embodiments of the present application, the antiglare surface is spherical in shape.

According to the shape of the lamp, the appearance shapes of the anti-dazzle surface and the grating are set to be spherical surfaces, so that the circular uniform light spots can be further formed.

In order to solve the technical problem, an embodiment of the application further provides a lamp.

Specifically, this lamps and lanterns include the lamp body, lamps and lanterns still include foretell grid 100, grid 100 set up in on the light-emitting end of lamp body.

The lamp adopts the grating 100, and the grating 100 is arranged on the light-emitting end of the lamp body, so that light spots irradiated by the lamp are more uniform and circular, and the lamp has a good anti-dazzle effect.
