In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
The grating provided by the embodiments of the present application will now be described. One side of the grating is arranged close to the light-emitting side of the light-emitting component, the light-in side of the grating is the light-in side of the grating, and the other side of the grating is the light-emitting side.
Referring to fig. 1, in one embodiment of the present application, the grating includes a main frame 1 and a plurality of grating walls 2, and the grating walls 2 are disposed in the main frame 1 and connected to an inner wall of the main frame 1. The grating wall 2 comprises a plurality of parallel transverse side walls 21 and a plurality of parallel longitudinal side walls 22, the transverse side walls 21 are parallel to the length direction of the main frame 1, the longitudinal side walls 22 are parallel to the width direction of the main frame 1, the transverse side walls 21 and the longitudinal side walls 22 are arranged in a staggered connection mode, the grating is provided with a plurality of grating holes 10 arranged in an array mode, and the transverse side walls 21 and the longitudinal side walls 22 are perpendicularly connected. Referring to fig. 2 and 3, the thickness of the grating wall 2 is different between the light-emitting side and the light-incident side, and therefore the size of the grating holes 10 is different between the light-emitting side and the light-incident side. The larger the size of the grating holes 10 is, the smaller the shielding effect on light is, and the effect of shielding glare cannot be achieved, the smaller the size of the grating holes 10 is, the larger the shielding effect on light is, when the size of the grating holes 10 is too small, too little light can be emitted through the grating, and the illumination is affected, so that the length L1 of the grating holes 10 on the light incident side is set to be 25mm to 30mm, and the width L2 of the light incident side of the grating holes 10 is set to be 18mm to 22 mm. Referring to fig. 4, a thickness a of the grating wall 2 on the light incident side is greater than a thickness b of the grating wall 2 on the light emergent side, so that after the light emitted by the light emitting element is reflected by the grating wall 2, the light emergent angle of the whole light is increased, and the grating increases the light emergent angle of the lamp and covers more areas on the premise of shielding glare. Specifically, the thickness a of the grid wall 2 on the light incident side is 2mm to 3.5mm, the thickness b of the grid wall 2 on the light emergent side is 0.5mm to 1.5mm, the excessive thickness of the grid wall 2 can block the light emitted by the light emitting component, and the excessive thickness of the grid wall 2 can affect the strength of the grid, so that the thickness b of the grid wall 2 on the light emergent side is set to be 0.5mm to 1.5mm, correspondingly, b is smaller than a, and the thickness a of the grid wall 2 on the light incident side is set to be 2mm to 3.5 mm. Both sides of the grating wall 2 are concave towards the inside of the grating wall 2 and are arc-shaped, so that the grating wall 2 can reflect light for many times and shield glare. The height h of the grating wall 2 is 7.5mm to 9.5mm, when the height h of the grating wall 2 is too high, too much light can be shielded, and when the height h of the grating wall 2 is too small, the glare shielding effect can not be achieved.
The grille in the above embodiment includes a main frame 1 and a grille wall 2, wherein transverse side walls 21 and longitudinal side walls 22 in the grille wall 2 are connected in a staggered manner to form grille holes 10 arranged in an array, a length L1 of the grille holes 10 on a light incident side is 25mm to 30mm, a width L2 of the grille holes 10 on the light incident side is 18mm to 22mm, a thickness a of the light incident side of the grille wall 2 is 2mm to 3.5mm, a thickness b of the light emergent side of the grille wall 2 is 0.5mm to 1.5mm, two sides of the grille wall 2 are recessed towards the inside of the grille wall 2 to form an arc, and a height h of the grille wall 2 is 7.5mm to 9.5mm, so that light emitted by a lamp can be shielded by the grille wall 2, glare is reduced, especially for persons close to the lamp, light entering human eyes can be greatly reduced, and eyes of persons such as teachers and the like can be protected.
Optionally, the surface of the grating is a surface with high reflectivity such as vacuum plating, and the reflected light can be increased, so that the light is uniform and the light extraction rate is increased.
In another embodiment of the present application, referring to fig. 2, the length L1 of the grid holes 10 on the light incident side is 27mm to 29mm, and the width L2 of the grid holes 10 on the light incident side is 19mm to 21 mm. When the grating holes 10 are too small in size, it may cause too little light to be emitted through the grating to affect illuminance, so that the length L1 of the grating holes 10 on the light incident side is set to be 27mm to 29mm, and the width L2 of the light incident side of the grating holes 10 is set to be 19mm to 21 mm. Accordingly, when the ratio of L1 to L2 is between 1.28 and 1.52, and the length direction of L1 is parallel to the length direction of the plane to be irradiated, glare in the direction parallel to the plane to be irradiated can be greatly reduced. Optionally, the length L1 of the grid holes 10 on the light incident side is 27.1 ± 0.1mm, and the width L2 of the grid holes 10 on the light incident side is 20.85 ± 0.1 mm. The ratio of L1 to L2 was 1.3.
In another embodiment of the present application, please refer to fig. 3 and 4, a thickness a of the light incident side of the grating wall 2 is 2.5mm to 3mm, and a thickness b of the light emergent side of the grating wall 2 is 0.8mm to 1.2 mm. In order to ensure the strength of the grille wall 2 and prevent light from being blocked, the thinnest part of the grille wall 2, that is, the part of the grille wall 2 close to the light-emitting side, the thickness b of the light-emitting side of the grille wall 2 can be set to be 0.8mm to 1.2 mm. Since the thickness a of the grid wall 2 on the light entry side is greater than the thickness b of the grid wall 2 on the light exit side, the thickness b of the grid wall 2 on the light exit side is accordingly set to 2.5mm to 3 mm. The larger the ratio of a to b is, the larger the difference between the thicknesses of the two ends of the grille wall 2 is, the smaller the effect of shielding glare is, and the smaller the difference between the thicknesses of the two ends of the grille wall 2 is, the smaller the light output of the lamp is, and the illuminance is affected, so the ratio of a to b is preferably 2.8 to 3.5. Furthermore, when the thickness a of the light incident side of the grating wall 2 is 2.8 +/-0.1 mm and the thickness b of the light emergent side of the grating wall 2 is 1 +/-0.1 mm, the strength of the grating wall 2 is ensured, most of glare shielded by the grating is ensured, and the light emergent rate of the lamp is also ensured.
In another embodiment of the present application, referring to fig. 2 and 4, the ratio of the length L1 of the grid hole 10 on the light incident side to the height h of the grid wall 2 is 2.8 to 3.5. The larger the ratio of L1 to h, the smaller the height of the grille, and the smaller the shielding effect of the grille wall 2 on glare; the smaller the ratio of L1 to h, the greater the height of the louver, the greater the shielding effect of the louver wall 2 on glare, but the less the light output of the luminaire, and even the less the illumination requirement. Therefore, the ratio of L1 to h is set between 2.8 and 3.5.
Further, referring to fig. 4, the height h of the grating wall 2 is 7.8mm to 9.2mm, and accordingly, the length L1 of the grating holes 10 on the light incident side is 25mm to 30mm, so that the grating can block glare and does not affect the light output amount. Preferably, the height h of the grid wall 2 is 8.5 ± 0.1mm, and the length L1 of the grid aperture 10 on the light entry side is 27.1 ± 0.1 mm.
The embodiment of the application also provides the grille lamp which can be a lamp in application scenes such as a blackboard lamp. The grille lamp that this application embodiment provided includes the grille lamp in above-mentioned arbitrary embodiment, still includes light emitting component, and light emitting component can be light source board isotructure, and the grid sets up in light emitting component's light-emitting side, when the grille lamp is applied to the scene of shining such as blackboard, bulletin board, can shelter from most glare, protection user's eyesight.
