Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a lighting assembly for a vehicle and a vehicle. Background Technology

[0002] In related technologies, in order to achieve the uniform ring lighting effect of automotive headlights, the main approach is to rely on multi-point light source layout and spliced ​​light guides to achieve coverage of the ring area. However, in order to ensure uniform lighting effect around the ring and overcome edge light attenuation and local unevenness, existing technologies often require a large number of LED particles to be arranged along the ring, which directly increases material costs. Therefore, how to reduce the cost of lamps has become the technical problem to be solved in this application. Utility Model Content

The diameter of the light guide gradually increases in the direction away from the concentrator. The light emitted by the light-emitting unit enters the concentrator through the light-inlet end of the concentrator. The tapered light guide causes the light to be conducted along the light guide during the expansion process. The light is uniformly distributed by the change of reflection angle through the inner wall of the light guide and reaches the annular light-emitting surface. The tapered structure replaces the distributed light emission of multiple LED particles by expanding the light, eliminating the need to arrange a large number of LEDs along the annular shape, reducing the number of LEDs used, directly reducing material costs, and thus reducing the cost of the lighting fixture.

[0032] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0033] The following is for reference. Figures 1-6 A lamp assembly 100 for a vehicle according to an embodiment of this application is described.

[0034] According to an embodiment of this application, a lighting assembly 100 for a vehicle includes: a concentrator 1, a light guide 2, and a light-emitting unit 3. One end of the concentrator 1 is provided with a light-incident end 11. The light guide 2 is provided at the other end of the concentrator 1 and is configured as a cone with a diameter that gradually increases in the direction away from the concentrator 1. An annular light-emitting surface 21 is formed on the side of the light guide 2 away from the concentrator 1. The light-emitting unit 3 is provided at one end of the concentrator 1 and is used to emit light toward the light-incident end 11.

[0035] In related technologies, in order to achieve the uniform ring lighting effect of automotive headlights, the main approach is to rely on a multi-point light source layout and spliced ​​light guides to cover the ring area. However, in order to ensure the uniform lighting effect of the ring circumference and overcome edge light attenuation and local unevenness, existing technologies often require a large number of LED particles to be arranged along the ring, which directly increases material costs.

[0036] It is understood that the light-emitting unit 3 is located on one side of the light-inlet end 11 of the light-emitting unit 1. The light emitted by the light-emitting unit 3 enters the interior of the light-inlet end 11 of the light-emitting unit 1. The light-emitting unit 1 converges the light, so that the dispersed light forms a concentrated beam that is transmitted to the light guide part 2. The light guide part 2 is constructed as a cone with a diameter that gradually increases in the direction away from the light-emitting unit 1. This causes the concentrated beam transmitted by the light-emitting unit 1 to undergo multiple reflections along the conical wall in the light guide part 2. As the diameter of the light guide part 2 gradually increases, the beam gradually expands radially during propagation, and finally forms an annular light-emitting surface 21 on the side of the light guide part 2 away from the light-emitting unit 1.

[0037] The vehicle lighting assembly 100 of this application embodiment achieves ring lighting through the light-emitting unit 3 in conjunction with the concentrator 1 and the light guide 2. It can be understood that since the light guide 2 is constructed as a cone with a gradually increasing diameter in the direction away from the concentrator 1, and the light-emitting unit 3 is located on the side with the smaller diameter, the light emitted by the light-emitting unit 3 is gathered by the concentrator 1 and then reflected or refracted along the interior of the light guide 2 before being transmitted to the ring light-emitting surface 21 to achieve ring light emission. This allows the ring light-emitting surface to be lit with only a small number of light-emitting units 3, reducing the number of LEDs used and directly reducing material costs.

[0038] Meanwhile, during the light transmission process, the converging effect of the light concentrator 1 ensures that the light entering the light guide 2 has sufficient intensity. The conical light guide 2 can achieve uniform light distribution through the change of the angle of reflection of the inner wall, avoiding differences in light intensity at various points of the annular light-emitting surface 21. Therefore, by setting the conical light guide 2, the uniformity of the annular light-emitting surface 21 can be ensured while covering the annular area with fewer light-emitting units 3, thereby reducing costs without reducing the lighting effect.

[0039] In short, the vehicle lighting assembly 100 according to the embodiments of this application has a tapered light guide 2. The diameter of the light guide 2 gradually increases in the direction away from the concentrator 1. The light emitted by the light-emitting unit 3 enters the concentrator 1 through the light-inlet end 11 of the concentrator 1. The tapered light guide 2 allows the light to be conducted along the light guide 2 during the expansion process. The light is uniformly distributed by the change of reflection angle through the inner wall of the light guide 2 and reaches the annular light-emitting surface 21. The tapered structure replaces the distributed light emission of multiple LED particles by expanding the light, eliminating the need to arrange a large number of LEDs along the ring, reducing the number of LEDs used, directly reducing material costs, and thus reducing the cost of the lighting fixture.

[0040] According to some embodiments of this application, a lighting assembly 100 for a vehicle has a concentrator 1 and a light guide 2 constructed as a single unit.

[0041] Understandably, after the conical structure of the light guide 2 is integrally formed, the curvature of its inner wall changes continuously and smoothly. The reflection angle of light within the light guide 2 gradually adjusts as the diameter increases, resulting in a more uniform distribution of light during radial expansion. Simultaneously, since the concentrator 1 and the light guide 2 are seamless, the energy transfer efficiency from the concentrator 1 to the light guide 2 is stable, preventing sudden changes in local light intensity due to gaps in the connection. This ensures that the light intensity difference at each point on the annular light-emitting surface 21 is effectively controlled, maintaining a uniform illumination effect for the complete ring. The integral design of the concentrator 1 and the light guide 2 eliminates the connection interface between them, thus avoiding potential dark areas or bright spots in that region.

[0042] According to some embodiments of the present application, a lighting assembly 100 for a vehicle has a concentrator 1 having a mounting groove 12 at the light-incident end 11 suitable for accommodating a light-emitting unit 3.

[0043] The light-emitting unit 3 is housed within the mounting groove 12. The inner wall of the mounting groove 12 forms a close-range enclosure with the light-emitting surface of the light-emitting unit 3, which can initially constrain the divergent light emitted by the light-emitting unit 3. Specifically, the light-emitting angle of the light-emitting unit 3 usually has a certain range, and the light from the sides of the light-emitting unit 3 and the light not facing the inside of the concentrator 1 is prone to scattering and loss in an unconstrained state. The inner wall of the mounting groove 12 can guide this light that might otherwise escape to the light-incident direction of the concentrator 1 through reflection, reducing the leakage of light into the non-working area and allowing more light to enter the interior of the concentrator 1 to participate in conduction.

[0044] According to some embodiments of the present application, a lighting assembly 100 for a vehicle has a concentrator 1 having a plurality of light-incident ends 11 spaced apart in the circumferential direction at one end.

[0045] It is understandable that, such as Figures 3-6As shown, the multiple light-incident ends 11 are spaced apart in the circumferential direction, which can provide an independent installation and light-incident channel for each light-emitting unit 3. The light entering the concentrator 1 through the multiple light-incident ends 11 of the multiple light-emitting units 3 will undergo preliminary mixing and conduction inside the concentrator 1. Since the light-incident ends 11 are spaced apart in the circumferential direction, the light they bring in forms multiple independent light beams in the circumferential direction inside the concentrator 1. During the propagation of these light beams in the light guide section 2, they cross and merge through reflection and refraction on the inner wall of the concentrator 1. The fusion of multiple light beams can avoid the intensity fluctuations or directional deviations that may exist in a single light beam, making the energy distribution of the light entering the light guide section 2 more balanced in the circumferential direction, and obtaining better light emission uniformity.

[0046] In some embodiments of this application, while achieving the same light-emitting effect, the power of the corresponding multiple light-emitting units 3 can be reduced because multiple light-emitting units 3 are provided. Since the light-emitting units 3 with lower power are used, the cost is controlled. At the same time, the heat dissipation of the light-emitting units 3 with lower power is also reduced, which is beneficial to the heat dissipation of the vehicle's cooling system.

[0047] In other embodiments of this application, multiple light-emitting units 3 can be of different colors to meet the needs of personalization and different light signals.

[0048] According to some embodiments of this application, a lighting assembly 100 for a vehicle has a concentrator 1 configured as an annular shape and a light guide 2 configured as a cone and connected to the other end of the concentrator 1.

[0049] It is understandable that, such as Figure 5-6 As shown, the concentrator 1 is ring-shaped, with a through-hole area at its center, providing a basic channel for airflow. The light guide 2 is a cone-shaped structure with a diameter that gradually increases away from the concentrator 1. After the light guide 2 is connected to the other end of the ring-shaped concentrator 1, the inner wall of the cone and the hollow area of ​​the concentrator 1 form an airflow channel. Air can enter from the hollow area of ​​the concentrator 1 and flow along the inner wall of the cone, increasing the contact area between the lamp assembly 100 and the air. This allows external cold air to contact the inner and outer walls of the concentrator 1 and the light guide 2 to participate in heat exchange. The ring-shaped structure of the concentrator 1 and the cone-shaped structure of the light guide 2 improve airflow efficiency and heat exchange frequency, enhance the system's heat dissipation capacity, and achieve the beneficial effect of system heat dissipation.

[0050] According to some embodiments of the present application, a lighting assembly 100 for a vehicle has a first optical pattern 22 formed on the radial inner sidewall and / or radial outer sidewall of the light guide portion 2 to form a total reflection surface on the radial inner sidewall and / or radial outer sidewall of the light guide portion 2.

[0051] The first optical pattern 22 alters the surface microstructure of the radial inner wall and / or radial outer wall, enabling the light incident on the wall to meet the condition of total internal reflection. Specifically, when light propagates within the light guide 2 and is incident on the wall with the first optical pattern 22, the concave and convex structure of the pattern can adjust the incident angle of the light to be greater than the critical angle between the light guide 2 and the air, thereby causing total internal reflection. This prevents the light from leaking out prematurely from the radial inner or outer wall, ensuring that the light can be transmitted along the extension direction of the light guide 2, and preserving sufficient energy for the uniform distribution of the light on the annular light-emitting surface 21.

[0052] Meanwhile, the total reflection surface formed by the first optical pattern 22 makes the propagation path of light in the light guide 2 more stable. Since the light guide 2 is a conical structure with a diameter that gradually increases away from the concentrator 1, the light will continuously adjust its propagation direction due to the change in the angle of the conical wall during propagation. The total reflection surface ensures that the light will not suffer local energy loss due to insufficient wall reflection efficiency. At the same time, the distribution of the first optical pattern 22 on the wall can be designed to be uniform and continuous, so that the total reflection effect in different areas of the light guide 2 is consistent, avoiding light intensity fluctuations caused by local reflection differences, thereby ensuring the uniformity of energy distribution of light in the circumferential and radial directions in the light guide 2.

[0053] According to some embodiments of this application, the light guide portion 2 of a vehicle lamp assembly 100 has a wall thickness of m, and satisfies the following condition: 5mm ≤ m ≤ 8mm.

[0054] It is understandable that the light guide 2, being a conical structure, requires reflection from the inner wall to achieve radial expansion and axial transmission of light. However, when the wall thickness is too thin (m≤5mm), the light is easily deflected during propagation due to insufficient structural strength of the light guide 2 itself. This causes the incident angle of the light reaching the inner wall to deviate from the critical angle, leading to premature leakage of some light and energy loss. Simultaneously, a thin wall thickness may result in an excessively short propagation path for the light within the light guide 2, insufficient reflections to achieve uniform distribution, and the formation of areas with insufficient brightness on the annular light-emitting surface 21. When the wall thickness is m≥8mm, the excessive thickness increases the propagation distance of the light within the light guide 2, increasing energy loss due to absorption in the material. This leads to an overall decrease in the intensity of the light reaching the annular light-emitting surface 21. Furthermore, an excessively thick wall may cause multiple reflections within the light guide 2, disrupting the uniformity of light distribution. Setting the wall thickness of the light guide 2 to 5mm≤m≤8mm ensures uniform light distribution.

[0055] According to some embodiments of this application, a lighting assembly 100 for a vehicle has a second optical pattern 23 formed on its annular light-emitting surface 21 for scattering light.

[0056] It is understandable that after light is transmitted to the annular light-emitting surface 21, there may be local directional concentration or intensity fluctuations before it is emitted, which can easily form bright spots or light-dark boundaries in the annular illumination area, disrupting uniformity. The second optical pattern 23, by forming an uneven microstructure on the annular light-emitting surface 21, scatters the light about to be emitted. Specifically, when light is incident on the light-emitting surface with the second optical pattern 23, the raised or recessed structure of the pattern changes the emission angle of the light, causing the originally parallel or small-angle converged light to be dispersed into multiple directions of emitted light. This makes the concentrated beam energy evenly distributed over a larger angle range, which can offset the directional differences accumulated when the light propagates in the light guide 2, disperse the locally excessively strong light to the surrounding area, and fill the locally weak areas, making the emitted light intensity at each point of the annular light-emitting surface 21 more uniform, further achieving a uniform light emission effect in the annular illumination area.

[0057] The lighting assembly 100 for a vehicle according to some embodiments of this application further includes: a light shield 4 disposed on the inner edge and / or outer edge of the annular light-emitting surface 21.

[0058] It is understandable that the annular light-emitting surface 21 is used to output light to form an annular lighting effect. When the light propagates in the light guide 2 and is emitted from the annular light-emitting surface 21, due to the influence of the light propagation angle and the edge of the light guide 2, some light may deviate radially inward or outward in the annular area, exceeding the preset annular lighting range. The deviated light will cause the boundary of the annular lighting area to become blurred, resulting in edge halo or stray light, which will interfere with the target lighting effect of the lamp.

[0059] When the light shield 4 is placed on the inner edge, it can block light rays that deviate towards the center of the ring, preventing these light rays from forming bright spots or overlapping light spots in the central area, thus affecting the lighting effect. When placed on the outer edge, it can block light rays that deviate outward, preventing stray light from illuminating adjacent components or unrelated areas of the road surface, reducing visual interference to other road users. Through physical blocking, the light shield 4 intercepts light rays that deviate beyond the preset ring range, avoiding light interference from non-target areas, enhancing the boundary clarity of the ring lighting, and ensuring the formation of a ring lighting effect with a clear outline and precise range.

[0060] According to some embodiments of this application, a lighting assembly 100 for a vehicle includes a light-emitting unit 3 comprising a circuit board 31, on which at least one light-emitting element 32 is disposed, the light-emitting element 32 being disposed opposite to a light-incident end 11 and adapted to emit light toward the light-incident end 11.

[0061] It is understood that at least one light-emitting element 32 is provided on the circuit board 31. The circuit board 31 can provide energy for the light-emitting element 32 to be lit. The light-emitting element 32 is positioned directly opposite the light-incident end 11 to ensure that the main light-emitting direction of the light-emitting element 32 is consistent with the light-incident axis of the condenser 1. The light emission of the light-emitting element 32 is directional. The light intensity is highest in the direction of the main light axis of the light-emitting element 32, and the intensity of the light deviating from the main light axis gradually decreases. The direct alignment makes the main light axis of the light-emitting element 32 coincide with the central axis of the light-incident end 11. At this time, most of the light emitted by the light-emitting element 32 can enter the condenser 1 with the smallest incident angle, reducing the reflection loss caused by the excessive incident angle. More effective light can be introduced into the condenser 1, improving the initial utilization rate of light and providing a sufficient energy basis for the uniform light emission of the subsequent light guide 2.
