Preferably, the honeycomb structure of the grid diffuser plate has a hole depth of 3mm and a hole diameter of 7 mm.

Preferably, a diffusion film is attached between the light guide plate and the grid diffusion plate.

By last, use the utility model provides an anti-dazzle panel light of honeycomb grid can obtain following beneficial effect: the utility model discloses a mode that light guide plate, diffusion barrier and grid diffuser plate combine realizes the light filtering diffusion to light, light changes the angle of 90 degrees through the optics site on the light guide plate after getting into the light guide plate and sends out, diffusion and reflection through the diffusion barrier make the light shape of whole lamp more even, light after diffusion and reflection is after the light filtering of grid diffuser plate, remove invalid miscellaneous light, make the light shape more even, both absorbed the side-emitting panel lamp and luminous evenly, the light shape is good, the light efficiency is high advantage, the defect that current anti-dazzle panel lamp glare value is high has effectively been overcome again, make blue light harm littleer; the anti-dazzle effect is better.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments of the present invention or the prior art will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive faculty.

Fig. 1 is an exploded view of an anti-glare panel lamp with a honeycomb grid according to an embodiment of the present invention.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

For the problem that a side-emitting classroom lamp has a large glare value in the existing classroom lighting lamp, and a straight-emitting classroom lamp has the problems of large thickness and poor lighting uniformity of the whole lamp.

In order to solve the above problems, the embodiment of the utility model provides a honeycomb grid anti-dazzle panel light, which not only absorbs the advantages of uniform light emission, good light shape and high light efficiency of a side light-emitting panel light, but also effectively overcomes the defect of high glare value of the existing anti-dazzle panel light, so that the blue light harm is smaller; the anti-dazzle effect is better.

Therefore, the cellular-grid anti-glare panel lamp provided by the embodiment adopts a light processing mode of side light emission and a cellular-grid diffusion plate to process light emitted by the lamp, so as to achieve the purpose of the invention. The specific implementation mode is as follows:

referring to fig. 1, the cellular grid antiglare panel lamp of the present embodiment includes a plate-shaped bottom plate 10 and a light guide plate 20, the bottom plate 10 and the light guide plate 20 are stacked with a gap therebetween, and a light emitting cavity is formed between the bottom plate 10 and the light guide plate 20. A diffusion film and/or a diffusion plate 50 may be attached to the light guide plate 20. If the diffusion film and the diffusion plate 50 are used together, the diffusion film and the diffusion plate 50 may be attached to each other to form an integral body.

The side department in the luminescent cavity is provided with lamp strip or lamp area 30, in order to comply with the market demand, this lamp strip or lamp area 30 is with low costs, LED lamp area 30 that market share is high, and in LED lamp area 30's mounting structure, can adopt the mounting structure who is formed with the hem in the edge of bottom plate 10 and/or light guide plate 20, or adopt the mounting structure who is provided with the frame in the edge of bottom plate 10 and light guide plate 20, LED lamp area 30 pastes on above-mentioned mounting structure, make whole lamp body be the side and give off light.

In order to achieve the anti-glare effect, the embodiment further includes a grid diffusion plate 40 attached to the light guide plate 20; the grill diffuser plate 40 has a honeycomb structure. The honeycomb structure of the grid diffuser plate 40 faces the light guide plate 20, and the honeycomb structure of the grid diffuser plate 40 has a hole depth of 3mm and a hole diameter of 7 mm.

In the grid diffuser plate 40 with the above technical parameters, the thickness of the grid diffuser plate 40 can be made to be 3mm, 5mm or 7 mm.

In the above structure, a rear cover plate 60 may be formed on the base plate 10; a bezel 70 is framed at the edges of the light emitting cavity, diffuser film and grid diffuser plate 40. The combination of the back cover plate 60 and the bezel 70 wraps the light emitting cavity, diffuser film and grille diffuser plate 40 to form a complete fixture.

The light is filtered and diffused by combining the light guide plate 20, the diffusion film and the grid diffusion plate 40, the light enters the light guide plate 20 and then changes the angle of 90 degrees with the light through optical dots on the light guide plate 20 to be emitted, and then is diffused and reflected by the diffusion film, so that the light shape of the whole lamp is more uniform, and after the diffused and reflected light is filtered by the grid diffusion plate 40, invalid stray light is removed, so that the light shape is more uniform, the advantages of uniform light emission, good light shape and high light efficiency of side light-emitting panel lamps are absorbed, the defect of high glare value of the existing anti-glare panel lamp is effectively overcome, and the harm of blue light is smaller; the anti-dazzle effect is better.

Aiming at the cellular grid anti-dazzle panel lamp with the structure, the following experimental data are obtained through UGR detection,

no matter the space size X =4H, 8H or 12H, the UGR value obtained by detection is mostly 16 or less, and thus a better antiglare effect can be achieved by adopting the technical scheme provided by the embodiment.

The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
