In this embodiment, the grille lamp 100 is installed at a higher position in a form of a ceiling mount, etc., and therefore, a first installation hole (not shown) may be further provided in the housing 1 to install the installation member 8 through the first installation hole. In order to avoid the deformation of the position of the hoisting hole on the shell 1 due to stress, the reinforcing sheet 9 can be arranged inside the shell 1, the reinforcing sheet 9 is provided with a second mounting hole corresponding to the first mounting hole, and the mounting part 8 penetrates through the first mounting hole and the second mounting hole simultaneously. Thereby, the mounting strength is improved while keeping the entire housing 1 and the grille lamp 100 light weight.

The grating plate 4 and its light-transmitting cells 40 are described in detail below.

Referring to fig. 3 and 4, two adjacent columns of transparent cells 40 are staggered, that is, the corners of one transparent cell 40 are aligned with the non-transparent portions 41 between two transparent cells 40 in the adjacent column. This is advantageous in that the area utilization rate of the louver 4 can be improved, and the width of the non-light-transmitting portion 41 can be easily kept uniform, thereby ensuring the uniformity of the light emitted from the grille lamp 100 as a whole.

Referring to fig. 5, the light-transmitting lattice 40 has a first side 401, a second side 402, a third side 403, a fourth side 404, a fifth side 405, and a sixth side 406, which are connected in sequence and are parallel and equal to each other, in any cross section, that is, the first side 401 and the fourth side 404 are parallel and equal to each other, the second side 402 and the fifth side 405 are parallel and equal to each other, and the third side 403 and the sixth side 406 are parallel and equal to each other. The length of the second side 402 is equal to the length of the third side 403, and the length of the first side 401 is greater than the length of the second side 402, so that the lengths of the second side 402, the third side 403, the fifth side 405, and the sixth side 406 are all equal and less than the lengths of the first side 401 and the fourth side 404. The light-transmitting cells 40 are generally in the shape of a regular hexagon elongated in one of the diagonal directions, and thus have an area larger than that of the regular hexagon defined by the length of the second side 402, and naturally have a larger light-transmitting area than that of the regular hexagon defined by the length of the second side 402.

Referring to fig. 5 to 7, a chamfer 42 is provided at a joint of two adjacent edges of the light-transmitting lattice 40, that is, the chamfer 42 is respectively provided at a joint of the first edge and the second edge, and a joint … … of the second edge and the third edge, and so on until a joint of the sixth edge and the first edge. The grid plate 4 can be made of plastic material by injection molding, and the chamfer 42 is arranged to facilitate complete mold filling and demolding. In one embodiment, the material of the grid plate 4 may be ABS (Acrylonitrile butadiene styrene) plastic, which has better flowability and excellent physical and mechanical properties.

As shown in fig. 6, the longest diagonal line of the light-transmitting cells 40 has a length L, which is defined as the length of the light-transmitting cell 40, and parallel to the diagonal line are a first side 401 and a fourth side 404, the distance between the first side 401 and the fourth side 404 is W, and the width W of the light-transmitting cell 40 is defined as the width of the light-transmitting cell 40, so that the light-transmitting cell 40 has an aspect ratio L/W. For a square grid, the aspect ratio is 1, and for a regular hexagonal grid, the aspect ratio is 1.414. The aspect ratio of the light-transmitting lattice 40 in this embodiment is greater than 1.414, and specifically may be greater than or equal to 1.5 and less than or equal to 3. Since the light-transmitting area of the light-incident side of the grating plate 4 determines the light efficiency, the length and width referred to in the above aspect ratio are both referred to the light-incident side.

With continued reference to fig. 6, the angle α 1 between the second side 402 and the third side 403 and the angle α 2 between the first side 401 and the sixth side 406 may not necessarily be maintained at 120 ° while ensuring that L/W is within a range of 1.5 or more and 3 or less. This is because the aspect ratio can be fine-tuned by adjusting α 1 and α 2 while keeping the lengths of the first side 401 and the second side 402 constant. For example, increasing α 1 may increase W, thereby decreasing the aspect ratio; increasing α 2 increases L, and thus the aspect ratio. Meanwhile, increasing W contributes more to the increase in the area of the light-transmissive lattice 40 than increasing L. Therefore, the light transmission area of the grid plate 4 can be increased while securing the aspect ratio by increasing α 1. The first side 401 and the fourth side 404 have a length L0, L0 being related to W, L, α 1, and α 2.

In one embodiment, α 1 is 120 ° to 124 ° and α 2 is 118 ° to 120 °.

Referring to fig. 8 to 10, the width D1 of the opaque portion 41 on the light incident side is greater than the width D2 on the light emergent side, and the side surface 410 of the opaque portion 41 substantially defines the first side 401 to the sixth side 406. The side surface 410 of the non-light-transmitting portion 41 may be a flat surface or a curved surface, and may be a straight line or a curved line in the cross section. The side surface 410 is preferably curved to provide more low angle light extraction than a flat surface. Specifically, the side surface 410 may be a circular arc with a radius R2, and R2 is preferably set large enough to allow a tangent at any point on the circular arc to reflect the incident light as a small angle light, i.e., an angle between a line connecting the center of the circular arc to the light-incident side edge and a line connecting the center of the circular arc to the light-exit side edge is not more than 90 °. Therefore, the light is incident on the arc and is reflected and then emitted towards the light emitting side, the included angle between the reflected light A and the reflected light B relative to the light emitting central line is smaller, namely the light emitting angle is smaller, and the unified glare value is reduced. In one embodiment, the width of the non-light-transmitting portion 41 (including the width D1 on the light incident side and the width D2 on the light emergent side) is 1 mm to 3 mm, preferably, the width D1 of the non-light-transmitting portion 41 on the light incident side is 2 mm to 3 mm, and the width D2 of the non-light-transmitting portion 41 on the light emergent side is 1 mm to 2 mm.

As shown in fig. 8, the height of the opaque portion 41, that is, the thickness of the grid plate 4 is H1. H1 can also affect the angle of the light exiting the light transmissive lattice 40. The larger the H1 is, the more likely the reflected light rays a and B are incident again on the adjacent one of the non-light-transmitting portions 41 before completely exiting the light-transmitting cell 40, and further the light exit angle is reduced by the inclined side surface 410 thereof, but conversely, too small a light exit angle causes a problem of insufficient illumination between the non-light-transmitting portions 41, which is expressed as a dark illumination area, such as insufficient illumination between light spots. Therefore, in a preferred embodiment, H1 is between 10 mm and 15 mm.

Similarly, the smaller the distance between two non-light-transmitting portions 41, that is, the smaller the length L and the width W of the light-transmitting lattice 40, the more likely that the reflected light rays a and B will be incident again on the adjacent non-light-transmitting portions 41 before completely exiting the light-transmitting lattice 40, and the further the light exit angle will be reduced. In this embodiment, because the length of the light-transmitting lattice 40 is large, the large-angle light is less in the light reflected by the side surfaces corresponding to the first side 401 and the fourth side 404, and the glare-eliminating effect is good; the ratio of the large-angle light rays is relatively more in the light rays emitted from the longitudinal section along the length direction, and therefore, the problem of glare is slightly obvious relative to the direction perpendicular to the glare.

Therefore, in one embodiment, the length of the light-transmitting grid 40 on the light-incident side is 22.5 mm to 36 mm, the width of the light-incident side is 12 mm to 15 mm, the aspect ratio is maintained at 1.5:1 to 3:1, and the glare problem in both the long direction and the wide direction can be considered.

In one embodiment, as shown in fig. 7 and 9, the light-transmitting cell 40 has a length of 29.59 mm on the light-incident side, a width of 14.3 mm on the light-incident side, an aspect ratio of about 2.07, and a length L0 of the first side 401 of 20.22 mm (where a chamfer 42 is provided, L0 refers to the linear length of the removed chamfer 42). α 1 is 122 ° and α 2 is 119 °. The width of the non-light-transmitting portion 41 on the light incident side was 2.8 mm, the width on the light exit side was 1.2 mm, the radius R2 of the side surface 410 of the non-light-transmitting portion 41 was 88.5 mm, and the height of the non-light-transmitting portion 41 was 12 mm. The radius R1 of chamfer 42 may be 1.6 mm.

In this regard, the above-described light transmission cell 40 of the present embodiment was optically verified by optical simulation. The comparative example used was a square grid with sides of 14.3 mm. In addition, in the present embodiment and the comparative example, the characteristics of the non-light-transmitting portion were completely the same, and the height thereof was 12 mm, the width thereof was 2.8 mm on the light incident side, the width thereof was 1.2 mm on the light exit side, the side surface thereof was a circular arc surface, and the radius thereof was 88.5 mm. The results of the comparison are shown in Table 1 below.

TABLE 1 optical simulation results of the square grids and the transparent grids of this example

Grid structure	Luminous flux/lm	Light effect lm/W	Unified glare value (UGR)
				Square grid	2844.59	72.89	15
Hexagonal light-transmitting grid	3403.08	87.3	16

By contrast, the light-transmitting cell 40 of the present embodiment can improve the luminous efficiency and luminous flux by about 20%, and can be suitable for the scenes such as offices, reading rooms, schools, hospitals, etc., while maintaining the uniform glare value UGR within 16, although the uniform glare value UGR is improved. Therefore, the grille lamp 100 of the present embodiment has a significant effect of improving the lighting effect and also has low glare.

In one embodiment, the side 410 of the opaque grid 40 is a mirror or plated surface, preferably a plated surface, which is more reflective and easier to bond with the ABS plastic material.

In using the grille lamp 100 of the present embodiment, the long direction of the light-transmitting compartment 40 should be set perpendicular to the viewing direction of human eyes. For example, in the embodiment, the grating plate 4 is rectangular, and the long direction of each light-transmitting cell 40 is parallel to the short side direction of the grating plate 4, so for example, for classroom illumination, the long side direction of the grating plate 4 should point from the blackboard to the direction of students. Therefore, the large-angle light rays can be reduced as less as possible in the most frequently used observation direction of the students, so that the discomfort of the eyes of the students is reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
