Description

Technical Field

[0001] This utility model belongs to the field of automotive taillight technology, and in particular relates to an automotive taillight module with nebula lights. Background Technology

[0002] With the development of new energy vehicle technology and the continuous advancement of battery technology, the taillight module used to display vehicle status can obtain sufficient power support, enabling it to present more display effects and enhance the overall aesthetics of the vehicle.

[0003] Currently, the display effect of automotive taillight modules is achieved by using light-shielding components to block the light beam, causing it to be transmitted outward from a specific area, thus creating a corresponding light beam effect in the outside world and improving the overall aesthetics of the vehicle. However, most existing technologies use simple light-transmitting holes for light-shielding components, which result in severe scattering of light during transmission and fail to achieve the expected display effect, thus having limited improvement on the overall aesthetics of the vehicle. Utility Model Content

[0027] This utility model embodiment provides a car taillight module with a nebula lamp, such as Figures 1-6 As shown, the automotive taillight module with nebula lights includes:

[0028] The main frame 110 has an outer lamp cover 120 on its outer side, and taillight assemblies 130 are provided at both ends of the main frame 110. The portion of the main frame 110 located between the taillight assemblies 130 is provided with an embedding groove 101.

[0029] The nebula lamp unit 200 includes a light filter component 220 and an LED module 230. The LED module 230 is disposed in the embedding groove 101, and the light filter component 220 is assembled between the LED module 230 and the outer lamp cover 120. The LED module 230 includes a lamp board 231 and a lamp holder 232, and the lamp board 231 is fixed on the lamp holder 232.

[0030] The light filter assembly 220 includes a first inner light filter 221, a second inner light filter 222, and a third inner light filter 223. The first inner light filter 221, the second inner light filter 222, and the third inner light filter 223 can be made of PC or PMMA red transparent material as the base material. The second inner light filter 222 has a nebula-shaped laser-engraved light-transmitting area 224. The light beam generated by the LED module 230 passes through the first inner light filter 221, the second inner light filter 222, and the third inner light filter 223 in sequence and is then transmitted outward from the outer lamp cover 120.

[0031] In this application, the light filter component 220 adopts a multi-layer stacked structure. The first inner filter 221 and the third inner filter 223 respectively filter the light beam before and after the light passes through the nebula-shaped laser-carved light-transmitting area 224, reducing the scattering of the light beam before and after transmission through the laser-carved light-transmitting area 224, and improving the display effect of the final nebula light beam. The second inner filter 222 is provided with a nebula-shaped laser-carved light-transmitting area 224, which works with the first inner filter 221 and the third inner filter 223 to filter the light emitted by the LED module 230 so that the emitted light beam is transmitted outward in a nebula structure, thereby optimizing the display effect of the taillight module and improving the aesthetics of the taillight.

[0032] In a preferred embodiment of this invention, the main frame 110 is further provided with a support unit 210 for fixing the lamp holder 232. The main frame 110 is also provided with an upper decorative panel 111 and a lower decorative panel 112, which are arranged at intervals to form an embedded groove 101. The second inner filter 222 and the third inner filter 223 are assembled between the upper decorative panel 111 and the lower decorative panel 112. A strip taillight 140 is also provided in the area between the upper decorative panel 111 and the inner wall of the main frame 110. The strip taillight 140 is linked with the taillight assembly 130. The taillight assembly 130 includes a traditional taillight, turn signal and brake light module, and its specific structure and control principle are the same as those of the prior art.

[0033] In this embodiment, the fixed end plate, the first bracket 211, the second bracket 212, and the lamp holder 232 are all connected by bolts. The lamp holder 232, the fixed end plate, and the first bracket 211 are connected to the main frame 110, and the two ends of the second bracket 212 are connected to the fixed end plate.

[0034] In a preferred embodiment of this invention, the surfaces of the first inner filter 221, the second inner filter 222, and the third inner filter 223 away from the lamp board 231 are provided with a gray coating. The coating is made of aluminum or chromium, and the light transmittance of the gray coating is 10% to 15%. The gray coating is applied using PVD coating technology, and its function is to reduce the light transmittance of the first inner filter 221, the second inner filter 222, and the third inner filter 223. The surface of the second inner filter 222 near the lamp board 231 is provided with a black paint layer, which does not cover the laser-engraved light-transmitting area 224. The black paint layer is opaque, and the light beam emitted by the LED module 230 can only pass through the second inner filter 222 through the laser-engraved light-transmitting area 224.

[0035] The specific processing method of the laser-engraved light-transmitting area 224 is as follows: First, black paint is sprayed on the surface of the second filter 222 near the lamp board 231 to form a black paint layer. Then, the corresponding nebula pattern is burned on the black paint layer by laser engraving technology to form the laser-engraved light-transmitting area 224.

[0036] In this embodiment, the cross-sectional curvature of the first filter inner 221 is in the range of 25–45 μm. -1 The second filter contains a 222 cross-sectional curvature ranging from 15 to 35 μm. -1 The curvature range of the cross-section of the third filter inner 223 is 10–40 μm. -1 The laser-engraved light-transmitting area 224 is a non-through-hole structure. It mainly uses laser engraving technology to process the nebula lamp structure inside the second filter 222. The laser-engraved light-transmitting area 224 is set inside the second filter 222 near the curved surface of the LED module 230.
