Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, specifically to a zoned light-emitting lighting structure. Background Technology

[0002] As a new generation of safe, reliable, energy-saving, and environmentally friendly green light source, LED lights have many advantages such as low power consumption, high luminous efficiency, good stability, and long service life. Currently, LED lights are widely used in the lighting field of the automotive industry. With the development of the new energy vehicle industry, the design of iconic logo lights on the front of cars has broken through the boundaries of traditional lighting functions. While ensuring design compliance, they are transforming from functional components to brand symbols. Customized logo lights that take into account both technological sense and artistry are creating a differentiated brand identification system through multi-dimensional innovation. Currently, LED lights are mainly composed of housing, circuit board, diffuser plate and light shield. For reference, see the luminous logo sign light and engineering device for engineering machinery with announcement number CN211526337U. The light shield ensures that the light color can be evenly presented on the corresponding letters. However, most existing logo lights display a static vehicle logo image. For example, consider the luminous logo light for construction machinery shown above. The circuit board behind the outer casing covers the entire area of ​​the casing, and the array of LEDs on the circuit board is arranged across the entire board, all powered simultaneously during use. To achieve a strong visual impact for the brand using dynamic lighting technology and parametric design language, an intelligent interactive module should be integrated, making the logo light an extension of human-vehicle interaction. For instance, customized lighting signals could be triggered based on charging status, requiring different areas to be illuminated at different charge levels to indicate the charging status. However, existing lights use the same color light source to illuminate the areas that need to be lit simultaneously. Although a light shield is provided, the letter areas on the light shield are connected. When different areas need to be illuminated separately (to reflect the charging status), light leakage occurs in areas that do not need to be illuminated. The existing sign light structure cannot guarantee against light leakage when different areas are illuminated separately. Utility Model Content

[0003] To achieve the above objectives, this utility model proposes a zoned light-emitting structure, including a housing, a PCB lamp board fixedly installed at the bottom of the housing, a light shield fixedly installed above the PCB lamp board, a light diffuser fixedly installed above the light shield, a lampshade provided above the light diffuser, and the side of the lampshade fixed to the side of the housing by bolts; The PCB lamp board is arranged with several groups of diode arrays at intervals. The light shield is equipped with several surrounding plates corresponding to the diode arrays, and the lamp cover is equipped with several light-emitting covers corresponding to the surrounding plates. This structure physically isolates the light emitted by different diode arrays through the surrounding plates of the light shield, effectively preventing halo diffusion and cross-lighting between areas, and realizing true independent light emission in different zones.

[0004] Further configured, the enclosure extends toward the light-diffusing plate, and the height of the enclosure is greater than the height of the diode array. The height of the enclosure exceeding that of the diode array can more thoroughly block light interference between adjacent light sources, prevent the light-diffusing plate above from receiving light from non-target areas, and further improve the purity and contrast of the zoned light emission.

[0005] Further configured, the light-diffusing plate is made of the same material, and the upper side of the light-diffusing plate is provided with a frosted surface. The frosted light-diffusing plate can convert point or line light sources into uniform surface light sources, eliminating the graininess and glare caused by point light emission from LEDs.

[0006] Further configured, the distance between the diode arrays is greater than the thickness of the enclosure, and the distance between the light-emitting covers is greater than the thickness of the enclosure. This spacing design ensures that the enclosure can be completely embedded in the gap between the light-emitting covers, forming a good physical light-shielding barrier.

[0007] Further configured, the diode array is arranged in a ring along the center of the PCB light board, and the diode array is set in a fan shape corresponding to each surrounding plate. The arrangement of the ring and the fan shape is structurally highly consistent with the circular brand logo, which improves the utilization rate of the light source and the visual integrity. This provides an optimized hardware foundation for realizing complex dynamic light language interaction functions.

[0008] Further configured, the side of the housing is provided with several countersunk bolt holes, and the side of the PCB lamp board is provided with several bolt protrusion holes corresponding to the countersunk bolt holes. After the bolt protrusion holes are inserted into the countersunk bolt holes, they are fixed by bolts. Through the matching structure of the countersunk holes and protrusion holes, the PCB lamp board can be quickly and accurately positioned and installed, avoiding offset or misalignment during the installation process.

[0009] A further configuration is provided, wherein several positioning protrusions are fixed at the bottom of the housing and on the inner sidewall of the housing, and the PCB lamp board is provided with a slot corresponding to the positioning protrusions. The cooperation between the positioning protrusions and the slots realizes the pre-positioning of the PCB lamp board and prevents it from moving before the bolts are tightened.

[0010] A further configuration includes a stud at the bottom of the housing, a mounting boss on the side of the enclosure corresponding to the stud, and a round hole on the PCB lamp board corresponding to the stud. The stud passes through the mounting boss and the round hole to fix the PCB lamp board and the light shield to the housing. The synchronous fixing of the light shield and the PCB lamp board is achieved through the cooperation of the stud and the mounting boss.

[0011] Further, the light-diffusing plate is provided with several grooves on its top, each groove having a round hole and rounded corners on its inner edges. The lower arm of the lampshade is provided with a bolt cylinder corresponding to the round hole on the groove. The light-diffusing plate and the lampshade are fixed by bolts passing through the bolt cylinder and the round hole. The groove and rounded corner design prevents the bolt head from protruding from the upper surface of the light-diffusing plate, preventing the formation of shadows or light spots and ensuring the overall uniformity of the light-emitting surface.

[0012] A further configuration is that the outer peripheral sidewall of the light-diffusing plate is bonded to the outer peripheral sidewall of the light-shielding plate, and the bonding design forms a sealed connection between the light-diffusing plate and the light-shielding frame, further preventing light from leaking from the edge and improving the overall light-shielding effect.

[0013] The beneficial effects of one or more of the above technical solutions: This invention features a diode array spaced apart on a PCB light board. A light shield and a light diffuser are arranged sequentially from bottom to top between the lampshade and the PCB light board. The light shield is separated by different diode arrays on the surrounding plate to prevent light leakage from different light-emitting areas. To ensure uniform light, a light diffuser is also placed between the light shield and the lampshade. This logo light uses the light diffuser and light shield to present a reasonable light source distance, working in conjunction with existing flowing light control programs to achieve uniform light emission and no light leakage in different zones via the PCB light board.

[0021] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0022] A zoned light emission structure, as shown in the reference Figure 1 A zoned light-emitting structure includes a housing 5. A PCB lamp board 4 is fixedly installed at the bottom of the housing 5. PCB is an abbreviation for printed circuit board, which is an important component in the electronics industry. A light shield 3 is fixedly installed above the PCB lamp board 4. A light diffuser 2 is fixedly installed above the light shield 3. A lampshade 1 is set above the light diffuser 2. The side of the lampshade 1 is fixed to the side of the housing 5 by bolts 53. The PCB light board 4 is equipped with several groups of diode arrays 41 at intervals. The light shield 3 is equipped with several surrounding plates 31 corresponding to the diode arrays 41. The lampshade 1 is equipped with several light-emitting covers 11 corresponding to the surrounding plates 31. This structure physically isolates the light emitted by different diode arrays 41 through the surrounding plates 31 of the light shield 3, effectively preventing halo diffusion and cross-lighting between areas, and achieving true independent light emission in different zones. Combined with the scattering effect of the light diffuser 2, the light in each light-emitting area is uniform and soft, improving visual quality and brand recognition, and is particularly suitable for dynamic lighting and interactive lighting scenarios.

[0023] The enclosure 31 extends toward the light diffuser 2. The height of the enclosure 31 is greater than the height of the diode array 41. The height of the enclosure 31 exceeds that of the diode array 41, which can more thoroughly block light interference between adjacent light sources, prevent the light diffuser 2 above from receiving light from non-target areas, further improve the purity and contrast of the zoned light emission, and ensure that there is no light leakage between different areas in scenarios such as charging status display.

[0024] The light-diffusing plate 2 is made of a transparent material that allows light to pass through. The upper side of the light-diffusing plate 2 is frosted. The frosted light-diffusing plate 2 can convert point or line light sources into uniform surface light sources, eliminating the graininess and glare caused by point LED light emission, making the display of the logo pattern softer and more high-end, and enhancing the technological feel and aesthetics of the product.

[0025] The distance between the diode array 41 is greater than the thickness of the enclosure 31, and the distance between the light-emitting covers 11 is greater than the thickness of the enclosure 31. This spacing design ensures that the enclosure 31 can be completely embedded in the gap between the light-emitting covers 11, forming a good physical light-shielding barrier. At the same time, the structure also reserves assembly tolerances to avoid light-shielding failure due to processing or installation errors, thereby improving the reliability and yield of the product.

[0026] The diode array 41 is arranged in a fan shape along the center of the PCB light board 4. This combination of ring and fan-shaped arrangement not only structurally matches the circular brand logo, improving light source utilization and visual integrity, but more importantly, it provides an optimized hardware foundation for realizing complex dynamic light language interaction functions. The ring layout ensures centrally symmetrical light output, and the fan-shaped partition design allows the lamps to be controlled via the CAN bus to precisely achieve multiple lighting modes: In welcome mode, each fan-shaped partition can light up clockwise in sequence with a breathing effect, creating a technologically advanced, progressive welcome light effect; in charging indicator mode, each fan-shaped partition can be independently controlled according to the battery percentage, dynamically and intuitively displaying the real-time charging progress with a combination of "partial constant light + partial breathing," enhancing the human-vehicle interaction experience; in logo constant light mode, all fan-shaped partitions can be lit simultaneously and evenly, ensuring the brand logo is clear, eye-catching, and without dark areas. This physical optical layout is the underlying key to realizing multiple intelligent interactive light languages, significantly enhancing the product's functionality and brand value.

[0027] Reference Figure 2 The housing 5 has several countersunk holes 51 on its side, and the PCB light board 4 has several protruding holes 52 on its side corresponding to the countersunk holes 51. After the protruding holes 52 are inserted into the countersunk holes 51, they are fixed by bolts 53. Through the matching structure of the countersunk holes and protruding holes, the PCB light board 4 can be quickly and accurately positioned and installed, avoiding offset or misalignment during installation, while improving assembly efficiency and facilitating large-scale production and maintenance.

[0028] Several positioning protrusions 54 are fixed at the bottom of the housing 5 and on the inner side wall of the housing 5. The PCB lamp board 4 is provided with a slot 55 corresponding to the positioning protrusions 54. The cooperation between the positioning protrusions 54 and the slot 55 realizes the pre-positioning of the PCB lamp board 4, preventing it from moving before the bolts 53 are tightened, ensuring the accurate correspondence between the diode array 41 and the light shield 3 enclosure 31, and improving the assembly accuracy and product consistency.

[0029] A stud 58 is provided at the bottom of the housing 5, and a mounting boss 56 is provided on the side of the enclosure 31 corresponding to the stud 58. A round hole 57 is provided on the PCB lamp board 4 corresponding to the stud 58. After the stud 58 passes through the mounting boss 56 and the round hole 57, the PCB lamp board 4 and the light shield 3 are fixed to the housing 5. Through the cooperation of the stud 58 and the mounting boss 56, the light shield 3 and the PCB lamp board 4 are synchronously fixed, ensuring that their relative positions are stable and avoiding structural loosening or light path deviation due to vibration or temperature changes, thereby improving the overall stability and durability of the structure.

[0030] Reference Figure 3 and Figure 4 The top of the light-diffusing plate 2 is provided with several recesses 21, each with a circular hole. The inner corners of the recesses 21 are rounded 23. A bolt sleeve 22 is installed on the lower side wall of the lamp cover 1 corresponding to the circular hole on the recess 21. The light-diffusing plate 2 and the lamp cover 1 are fixed by bolts passing through the bolt sleeve 22 and the circular hole. The design of the recesses 21 and the rounded corners 23 prevents the bolt heads from protruding from the upper surface of the light-diffusing plate 2, preventing the formation of shadows or light spots and ensuring the overall uniformity of the light-emitting surface. At the same time, the bolt sleeve 22 enhances the connection strength, prevents the lamp cover 1 from deforming under pressure, and improves the vibration resistance of the product in the vehicle environment.

[0031] The light-diffusing plate 2 is bonded to the outer periphery of the light-shielding frame 3. The bonding design forms a sealed connection between the light-diffusing plate 2 and the light-shielding frame 3, further preventing light leakage from the edge and improving the overall light-shielding effect; at the same time, it enhances the overall structural integrity and prevents the light-diffusing plate 2 from shifting or making abnormal noise in a vibrating environment.

[0032] In charging indicator mode, the specific illuminated states of different areas are as follows (see reference). Figure 5 , This logo light uses CAN control to achieve three lighting modes: welcome mode, charging indicator mode, and logo mode. Welcome mode: Different zones illuminate sequentially clockwise, maintaining a breathing effect for 1.5 seconds before turning off. Charging indicator mode: When the vehicle is charging, the logo light displays some zones continuously while others exhibit a breathing effect based on the vehicle's charging percentage. Logo mode: When the vehicle's position lights are on, all zones of the logo light illuminate and remain constantly lit.

[0033] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
