Description

Technical Field

[0001] This application relates to the field of automotive ADS lamp technology, and specifically discloses a compact ADS lamp light-emitting structure. Background Technology

[0002] In the current environment, with the improvement of intelligent driving, ADS lights, as a type of functional light that can indicate to surrounding traffic participants that the vehicle is in assisted driving mode and improve safety, are becoming increasingly popular.

[0003] Regarding the ADS light: It refers to the external indicator light displayed when the vehicle is in autonomous driving mode. It is usually blue or turquoise and is used to convey vehicle status information to surrounding road users.

[0004] Conventional ADS lights are mostly integrated inside headlights / taillights, employing a structure of lamp housing + reflector + circuit board (with LED light source) + thick-walled light guide + light distribution lens. The lamp housing and light distribution lens primarily serve a sealing function, while the reflector + circuit board (with LED light source) + thick-walled light guide constitute the main optical system. However, this structure requires a relatively large overall size and space for the lighting fixture.

[0005] See the attached instruction manual for details. Figure 1 Existing ADS lights are mostly integrated inside headlights / taillights, using a lamp housing + reflector + circuit board (with LED light source) + thick-walled light guide + light distribution lens. The lamp housing and light distribution lens are mainly sealed by welding to protect the internal optical system from external dirt. The reflector + circuit board + thick-walled light guide is the main optical system. However, in this structure, the number of lamp components is large, and space is needed between different components for effective fixation. The required size space is relatively large, and the process is complex and costly.

[0006] A compact ADS lamp light-emitting structure is proposed, which reduces space requirements and can be flexibly applied to different vehicle models.

[0007] The present invention provides a compact ADS lamp light-emitting structure to solve the above-mentioned problems. Summary of the Invention

[0008] The purpose of this invention is to solve the problem that traditional ADS lamps are not compact enough and require a large installation space.

[0009] To achieve the above objectives, the present invention provides the following basic solution: A compact ADS lamp light-emitting structure includes a lamp housing and a thick-walled light distribution integrated component bonded to the lamp housing; A circuit board and an LED light source are fixedly mounted on the lamp housing, and the LED light source shines directly onto the thick-walled light distribution integrated component. Thick-walled light distribution integrated component: including end corner, lens part and thick-walled part, the end corner, lens part and thick-walled part are integrally formed, the end corner is connected to the lamp housing, the lens part is used for LED light source diffusion, and the thick-walled part controls the scattering angle of the light from the LED light source.

[0010] Furthermore, the lamp housing is made of metal.

[0011] Furthermore, the inner side of the lamp housing has a mounting groove for placing the circuit board, which is integrated with the LED light source. It also includes a bracket, one end of which is fixedly mounted with the circuit board, and the other end of which is fixedly mounted with the LED light source. The bracket is provided with locking screws to fix the circuit board.

[0012] Furthermore, the end corner is bonded to the lamp housing with adhesive, and a blocking block is provided at the end corner position. After the end corner is snapped into the lamp housing, it cooperates with the blocking block to form a filling groove. By filling the filling groove with adhesive, the thick-walled light distribution integrated component is fixed to the lamp housing.

[0013] Furthermore, it also includes a wiring harness that is electrically connected to the circuit board, with the harness extending from the inside of the lamp housing.

[0014] Furthermore, the end of the thick-walled portion closest to the LED light source is the light-emitting surface, and patterns are provided on the light-emitting surface.

[0015] Furthermore, the lens portion is arranged at an angle based on the centerline of the LED light source.

[0016] The principle and effect of this solution are as follows: 1. Compared with existing technologies, this device has a simple structure and ingenious design. Through the reasonable redesign of the lamp housing, the reflector is eliminated and replaced with direct LED light.

[0017] 2. Compared with existing technologies, this device reduces functional parts through optical redesign, resulting in a rapid decrease in cost. Furthermore, it has reduced size and space requirements, making it suitable for different vehicle models and installation locations, and has a high degree of platformization.

[0018] 3. Compared with the existing technology, this device redesigns the optical form, combining the thick-walled light guide and the light distribution lens into one part, namely the thick-walled light distribution integrated component. The thick-walled light distribution integrated component serves as both an optical component and a protective component. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] The reference numerals in the accompanying drawings include: lamp housing 1, reflector 2, circuit board 3, thick-walled light guide 4, light distribution lens 5, filling groove 7, blocking block 8, mounting groove 9, bracket 11, LED light source 12, locking screw 13, end corner 14, lens part 15, thick-walled part 16.

[0023] Existing technologies such as Figure 1 As shown: Existing ADS lamps are mostly integrated inside headlights or taillights, employing a lamp housing 1 + reflector 2 + circuit board 3 (with LED light source 12) + thick-walled light guide 4 + light distribution lens 5. The lamp housing 1 and light distribution lens 5 are mainly sealed by welding to protect the internal optical system from external contaminants. The reflector 2 + circuit board 3 + thick-walled light guide 4 constitute the main optical system. The LED light source 12 emits light through the circuit board 3, and the light shines directly onto the light distribution lens 5 through the reflector. The light distribution lens 5, through a combination of prisms and lenses, refracts the parallel beam focused by the reflector 2, dispersing the light over a wider area. This type of lamp has a large number of components, requiring space for effective fixation between different parts, resulting in a large required size, complex manufacturing process, and high cost. Therefore, a compact ADS lamp light-emitting structure is proposed, as detailed below. Figure 2 As shown: First, the lamp housing 1 is still present. The improvement in the lamp housing 1 lies in the material; the material of the lamp housing 1 has been changed from PC+ABS to ADC, which is a metallic material with certain thermal conductivity. Then, a mounting slot 9 is opened on the inner side of the lamp housing 1. This mounting slot 9 is used to place the circuit board 3. In this case, the circuit board 3 is still an integrated component of the circuit board 3 and the LED light source 12. The circuit board 3 is fixed based on the bracket 11, such as... Figure 2As shown, the left end of the bracket 11 is the circuit board 3, and the right end of the bracket 11 is the LED light source 12. The circuit board 3 is then placed in the mounting slot 9. The bracket 11 is equipped with locking screws 13, which are used to fix the circuit board 3. After the circuit board 3 is fixed, the LED light source 12 is also fixed. Since ADC material is used, the heat on the circuit board 3 is dispersed through the heat conduction of the metal, thereby improving the luminous efficiency of the LED light source 12.

[0024] After the lamp housing 1 is rearranged, the reflector 2 can be removed and replaced with a direct LED type. Replacing it with a direct LED type is beneficial for the subsequent use of thick-walled light distribution integrated components.

[0025] This device eliminates the light distribution lens 5 and the thick-walled light guide 4, and replaces the light distribution lens 5 and the thick-walled light guide 4 with a new thick-walled light distribution integrated component.

[0026] Regarding the thick-walled light distribution assembly: The entire thick-walled light distribution assembly includes an end corner 14, a lens section 15, and a thick-walled section 16.

[0027] Regarding end corner 14: It is mainly used to snap onto the lamp housing 1. A blocking block 8 is provided at the end corner 14 position. After the end corner 14 snaps onto the lamp housing 1, it forms a filling groove 7 with the blocking block 8. By filling the filling groove 7 with glue, the thick-walled light distribution integrated component is fixed to the lamp housing 1.

[0028] Regarding the thick-walled section 16: Since the reflector 2 has been removed and replaced with a direct LED light source, the common thick-walled section 16 usually includes an incident light surface and an exit light surface: the incident light surface is equipped with a collimating lens array to convert the light from the light source into parallel light, and the exit light surface: the light scattering angle is controlled by a microstructure to balance uniformity and aesthetics. Since the direct LED light source is replaced, the collimating lens array is no longer needed, and the entire structure is more compact. Only an exit light surface needs to be provided. In this case, the exit light surface is provided with a pattern to control the light scattering angle.

[0029] Regarding the lens section 15: The conventional light distribution lens 5 uses a combination structure of prism and lens to refract the parallel light beam gathered by the reflector 2, so that the light is dispersed to a wider area. In this case, there is no need for a prism. The lens section 15 is arranged at an angle based on the center line of the LED light source 12. Since the conventional prism is used for refraction, and the light-emitting surface of the thick-walled section 16 has replaced the function of the prism, this case only needs the lens section 15, and the light can be emitted through the lens section 15.

[0030] The wiring harness used to electrically connect the circuit board 3 in this case is not shown. The wiring harness is used to power the circuit board 3 and thus control the LED light source 12.

[0031] This device solves the problem that traditional ADS lamps are not compact enough and require a large installation space.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
