It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. The described embodiments are only a part of the embodiments of the present utility model, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0028] See Figures 1 to 6 , the present utility model provides a grid lamp, including a base 1, a lamp group 2 and an optical element 3. Among them, the lamp group 2 is located in the space enclosed by the base 1 and the optical element 3; the optical element 3 includes a light - distribution lens, a metal light - transmissive layer 3a and a light - impermeable paint layer 3b. The metal light - transmissive layer 3a is located on the light - transmissive surface of the light - distribution lens. The light - impermeable paint layer 3b is arranged on the metal light - transmissive layer 3a and is provided with a light - leakage area having a preset shape, and the light - leakage area exposes the metal light - transmissive layer 3a; the lamp beads 22 of the lamp group 2 are arranged in one - to - one correspondence with the light - leakage area.

[0029] In the present utility model, the lamp beads 22 of the lamp group 2 are arranged in one - to - one correspondence with the light - leakage area. On the one hand, it can ensure that the light - leakage area can emit a metallic luster. On the other hand, since the lamp beads 22 of the lamp group 2 are in one - to - one correspondence with the light - leakage area, the uniformity of light emission can be ensured. Thus, the grid lamp provided by the present utility model can ensure its own optical uniformity on the premise of emitting a metallic luster.

[0030] It should be noted that the metal light - transmissive layer 3a of the present utility model can emit a metallic luster when light passes through. The metal light - transmissive layer 3a can be indium tin oxide (ITO), metal mesh film (MetalMesh), metal photonic crystals (MetalPhotonic Crystals, MPCs), special coating technology, transparent fiberglass, nano - scale metal microstructures, metal nanowire transparent electrodes, etc. As long as it has a light - transmissive function on the premise of having a metallic luster, the coating structure is within the scope of protection of the present utility model.

[0031] The light - impermeable paint layer 3b is light - impermeable or has a very low light - transmittance and is used to form the overall tone of the entire grid lamp. Specifically, the light - impermeable paint layer 3b is black paint. Of course, it can also be paint of other colors, and the color can be adjusted according to actual needs, and no more description is given here.

[0032] The function of the light leakage area is to expose the metallic luster. The light leakage area can be formed by laser engraving. The light leakage area is processed into a predetermined shape by laser engraving to expose the metallic light-transmitting layer 3a.

[0033] In some embodiments of the present invention, the light distribution mirror includes a support portion 31 and a light-transmitting portion 32, wherein the support portion 31 is arranged around the light-transmitting portion 32, and the light-transmitting surface is formed on the outer surface of the light-transmitting portion 32. It should be explained here that the light-transmitting portion 32 has an outer surface and an inner surface, wherein the inner surface cooperates with the base 1 to form a space for accommodating the lamp group 2, and the outer surface of the light-transmitting portion 32 is used to form a modeling carrier of the grille lamp.

[0034] The light-transmitting portion 32 is snap-connected with the supporting portion 31, or welded. In order to increase the connection strength between the light-transmitting portion 32 and the supporting portion 31, in some embodiments, the parts where the light-transmitting portion 32 and the supporting portion 31 match are provided with protrusions and recesses that match each other. It can be understood that in one embodiment, the light-transmitting portion 32 is provided with a protrusion, and the supporting portion 31 is provided with a recess; in another embodiment, the light-transmitting portion 32 is provided with a recess, and the supporting portion 31 is provided with a protrusion; in a third embodiment, the light-transmitting portion 32 is provided with a protrusion and a recess, and the supporting portion 31 is provided with a recess and a protrusion.

[0035] For the sake of aesthetics, in some embodiments, protrusions and recesses are disposed on the inner surface of the light-transmitting portion 32 .

[0036] In some embodiments, the light-transmitting portion 32 is a single-color injection-molded part, and the light-transmitting portion 32 is white, which can effectively save the processing cost of the grille lamp.

[0037] In order to improve the metallic luster, the outer surface of the light-transmitting portion 32 has a plurality of decorative portions 33, and the decorative portions 33 are provided with a metallic light-transmitting layer 3a, and the shape of the decorative portions 33 matches the shape of the light-leaking area. The three-dimensional sense of the metallic luster can be increased by providing the decorative portions 33. The shape of the decorative portions 33 is set according to actual needs.

[0038] In the figure, the decorative portion 33 is a strip-shaped structure. Specifically, the strip-shaped structure is formed by protruding from the outer surface of the light-transmitting portion 32, or the strip-shaped structure can also be formed by being recessed into the outer surface of the light-transmitting portion 32.

[0039] In addition, the plurality of decorative parts 33 are evenly arranged along a preset direction, which can be understood as the length direction or width direction of the grille light, or any direction between the length direction and the width direction.

[0040] The above mainly introduces the structure of the light distribution mirror. In some embodiments, the lamp assembly 2 includes a lamp board 21 and lamp beads 22 arranged on the lamp board 21. The lamp beads 22 and the decorative parts 33 are arranged in a one-to-one correspondence.

[0041] The shape of the lamp bead 22 can also be consistent with the extending direction of the decoration part 33. For example, when the device is in a strip structure, the lamp bead 22 is in a strip structure or a plurality of lamp beads are arranged in an extending strip structure.

[0042] In some embodiments, the base 1 is connected to the optical element 3 by welding or screw connection.
