Description

Technical Field

[0001] The utility model relates to the technical field of light-blocking structures of lamps, in particular to a pixelated light-blocking structure of lamps. Background Art

[0002] A Chinese patent (patent number ZL 202222227589.1, announcement date 2022.08.23) discloses a direct-incident ISD signal light, comprising: a circuit board, an anti-cross-light baffle, and a thick-walled optical system; the circuit board, the anti-cross-light baffle, and the thick-walled optical system are assembled and arranged in sequence, and the anti-cross-light baffle is sandwiched between the circuit board and the thick-walled optical system; a plurality of light sources are provided on the circuit board, a plurality of openings are provided on the anti-cross-light baffle, and the thick-walled optical system includes a plurality of thick-walled optical units; the openings correspond one-to-one to the thick-walled optical units, and the thick-walled optical units are located within the openings; at least one light source is correspondingly provided at the thick-walled light incident surface of the thick-walled optical unit; the anti-cross-light baffle is used to block light emitted from the peripheral side walls of the thick-walled optical unit; light emitted by the light source reaches the thick-walled light incident surface of the thick-walled optical unit, and the light propagates inside the thick-walled optical unit to reach the thick-walled light exit surface of the thick-walled optical unit, and is emitted through the thick-walled light exit surface. This patent adopts the solution of light-emitting diode + thick-walled inner lampshade, which is currently mainly used in pixelated signal lights. The solution is to use a thick-walled inner lampshade with multiple light-emitting surfaces, and then install a non-luminous two-color decorative ring or bracket on the outside of the thick-walled inner lampshade to block the light leakage between different light-emitting surfaces of the thick-walled inner lampshade. However, since the thick-walled inner lampshade itself is an integrated part, there are connections between different light-emitting surfaces, which leaves a light guide path for the light, so it cannot completely block the light between different light-emitting windows.

[0003] A Chinese patent (patent number ZL 202222873594.X, published on April 14, 2023) discloses a pixelated interactive signal light comprising a mounting plate, a two-color inner structure, and a light-blocking layer. The two-color inner structure comprises a scattering structure and multiple opaque structures, with the opaque structures spaced apart on the scattering structure. The mounting plate is positioned at one end of the opaque structure away from the scattering structure, and a light source is disposed on the mounting plate, corresponding to the gaps between adjacent opaque structures. The opaque structures are configured to absorb or reflect some light. The light-blocking layer is disposed on the light-emitting surface of the scattering structure, corresponding to some of the opaque structures, and is configured to block or absorb some light. This patent utilizes a light-emitting diode (LED) + two-color inner lampshade solution, currently primarily used in pixelated signal lights. This solution utilizes a two-color injection-molded inner lampshade, divided into a light-emitting area and a non-light-emitting area. The two-color injection molding utilizes a covering structure, resulting in connections between the different light-emitting areas, which still cannot completely prevent light crosstalk.

[0031] The light-blocking structure of the pixelated lamp according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7The pixelated lamp light-blocking structure of the present invention is composed of a plurality of unit modules, each of which forms a light-emitting window, and a plurality of unit modules form a plurality of light-emitting windows; the unit module includes a two-color decorative ring 1, a bracket 2 and a PCB board 3, and the PCB board 3, the bracket 2 and the two-color decorative ring 1 are arranged in sequence along the incident direction of light from left to right, and the bracket 2 is located between the two-color decorative ring 1 and the PCB board 3, the right end of the bracket 2 is fixed on the two-color decorative ring 1, and the left end of the bracket 2 is fixed on the PCB board 3; the two-color decorative ring 1 includes a first-color decorative ring non-luminous portion 11, a second-color decorative ring luminous portion 12 and a decorative ring light-blocking groove 13, and the colors of the first-color decorative ring non-luminous portion 11 and the second-color decorative ring luminous portion 12 are different. The non-luminous part 11 of the first color decorative ring is located on the outer circle of the luminous part 12 of the second color decorative ring, and the decorative ring light-blocking groove 13 is arranged on the left side of the non-luminous part 11 of the first color decorative ring; the bracket 2 includes a bracket body 21, a reflecting surface 22 and a light-blocking rib 23, the reflecting surface 22 is arranged on the inner surface of the bracket body 21, and the light-blocking rib 23 is arranged on the right side of the bracket body 21, and the light-blocking rib 23 cooperates with the decorative ring light-blocking groove 13 to block light; after the light is emitted through the light source 4 installed on the PCB board 3, it is emitted through the luminous part 12 of the second color decorative ring, and the light can and can only be emitted from the luminous part 12 of the second color decorative ring.

[0034] The reflective surface 22 provided on the bracket 2 serves to enhance light efficiency and can be formed using a coating process or a high-reflectivity material. Specifically, when a coating process is used, the reflective surface 22 is formed by coating the surface of the bracket 2, or alternatively, the reflective surface 22 is made of a high-reflectivity material. Specifically, the reflective surface 22 can be an aluminum film electroplated on the inner surface of the bracket 2 using an aluminum plating process. Alternatively, the reflective surface 22 can be a chromium film electroplated on the inner surface of the bracket 2 using a chrome plating process. When a high-reflectivity material is used, PC, etc. can be used.

[0035] The main body of the bracket 2, ie, the bracket body 21, is made of a mixed material of PC and ABS, or made of any one of PC and ABS.

[0036] The light-blocking rib 23 is loosely matched with the light-blocking groove 13 of the decorative ring. The two-color decorative ring 1 and the bracket 2 can be connected by means of clamping, screw locking, riveting, welding, gluing, etc.

[0037] The gap d between two adjacent light-emitting windows is 2 mm.

[0038] Several unit modules are arranged up and down, and the left sides and right sides of two adjacent unit modules are aligned.

[0039] The first color bezel non-luminous portion 11, the second color bezel luminous portion 12 and the bezel light-blocking groove 13 are an integrated structure. The bracket body 21, the reflective surface 22 and the light-blocking rib 23 are an integrated structure.

[0040] The non-luminous portion 11 of the first color bezel is mainly made of an opaque material, which serves as a light shield and decoration.

[0042] The non-luminous portion 11 of the first color decorative ring and the luminous portion 12 of the second color decorative ring are injection molded. The specific method is: during injection molding, the non-luminous portion 11 of the first color decorative ring is first injection molded, and then silicone is injected into the pattern surrounded by the non-luminous portion 11 of the first color decorative ring. After vibration and squeezing out the excess silicone, a complete two-color decorative ring 1 is finally formed.

[0043] The second-color bezel luminous portions 12 between different luminous windows are not connected, thus achieving complete light isolation between the different luminous windows. When the second-color bezel luminous portion 12 is made of transparent silicone, the silicone between the different luminous windows is not connected, further achieving complete light isolation between the different luminous windows. In other words, by using silicone extrusion in the luminous area, the pixelated signal light achieves complete light blocking between the different luminous windows.

[0044] Figure 4 The smallest unit is shown, that is, one unit. After a plurality of units are combined, different units are shielded from light by the non-luminous portion 11 of the first color decorative ring and the bracket 2 .

[0045] This new pixelated light-blocking structure achieves complete light blocking across the different light-emitting areas of a pixelated signal light using only a single component. It also features a compact design, with spacing of 2mm between the different light-emitting windows. Specifically, it solves the problem of light crosstalk between the different light-emitting surfaces of a pixelated taillight within a compact footprint, enabling independent, cross-talk-free illumination of each surface and enhancing the lighting effect. Furthermore, the number of components is reduced, eliminating the need for additional light-blocking components and enabling the consolidation of components, improving assembly convenience and reducing costs.

[0046] Example 2

[0047] See Figure 5Compared with Example 1, Example 2 differs in that: bracket 2 is eliminated, and PCB board 3 is directly fixed to the two-color bezel 1 to block light. Specifically, the pixelated lamp light-blocking structure of the present invention is composed of a plurality of unit modules, each of which forms a light-emitting window, and a plurality of unit modules form a plurality of light-emitting windows. The unit modules include a two-color bezel 1 and a PCB board 3. The PCB board 3 and the two-color bezel 1 are arranged in sequence along the incident direction of light from left to right, and the PCB board 3 is fixed to the left end of the two-color bezel 1. The two-color bezel 1 includes a first-color bezel non-luminous portion 11 and a second-color bezel luminous portion 12, with the first-color bezel non-luminous portion 11 located outside the second-color bezel luminous portion 12. After light is emitted from a light source mounted on the PCB board 3, it is emitted through the second-color bezel luminous portion 12, and light can only be emitted from the second-color bezel luminous portion 12.

[0048] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them.
