Description

Technical Field

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

[0002] With the rapid development of new energy vehicles, the technical requirements for vehicle lights, as an important exterior component, are becoming increasingly stringent. Among these requirements, space utilization has become one of the key areas of focus for OEMs. How to rationally arrange various parts and components within a limited space is posing many challenges for engineers. In particular, for some light assemblies with a slender and narrow body, if the light source is placed directly on the backlight side of the light assembly away from the light-emitting surface, the light will pass directly through the thin-walled light-transmitting component and produce obvious glare. The space between the light assembly and the surrounding sheet metal is also narrow, making the arrangement of the light source wiring harness connectors more difficult. Utility Model Content

[0003] In view of this, in order to solve at least some of the problems mentioned above, this application provides a lamp assembly and a vehicle.

[0004] This application provides a lamp assembly, including:

[0005] case;

[0006] A light-emitting element, the edge of which is connected to the housing, and a receiving cavity is formed between the light-emitting element and the housing; the dimension of the light-emitting element along a first direction is larger than its dimension along other directions, and it is used to receive and emit light along a preset main light-emitting direction, wherein the first direction intersects the preset main light-emitting direction;

[0014] The vertical plate portion is connected to the side surface of the horizontal plate portion away from the light source plate; the power transmission component passes through the light source plate, the horizontal plate portion and the vertical plate portion in sequence, and is electrically connected to an external connector after the vertical plate portion is bent in a second direction.

[0015] In one embodiment,

[0016] The horizontal plate has a positioning post on the side near the light source plate. The light source plate has a positioning hole corresponding to the positioning post.

[0019] In one embodiment, the housing includes a plug-in port that penetrates the housing, and the light source module has a positioning boss on one side near the housing. The positioning boss is embedded in the plug-in port, and the power transmission component passes through the positioning boss and extends into the plug-in port.

[0020] The aforementioned light assembly has at least the following beneficial technical effects:

[0021] The lamp assembly includes a housing, a light-emitting element, a light guide, and a light source module. Both the light guide and the light source module are located within a receiving cavity. The light source module and the light guide are arranged sequentially along a first direction, with the light-emitting surface of the light source module facing the light guide.

[0046] Reference Figures 1-4 In some embodiments, a lamp assembly is provided, including a housing 10, a light emitting element 11, a light guide element 13, and a light source module 14.

[0047] The light-emitting component 11 is connected to the housing 10, and a receiving cavity 12 is formed between the light-emitting component 11 and the housing 10. The receiving cavity 12 provides installation space for the light guide component 13 and the light source module 14, and isolates the light guide component 13 and the light source module 14 from the external environment, thus playing a protective role.

[0048] The dimension of the light-emitting element 11 along the first direction is larger than its dimension along other directions. The light-emitting element 11 is used to receive and emit light along a preset main light-emitting direction (Y direction). The first direction intersects with the preset main light-emitting direction. Figure 1 and Figure 2 The X direction is the first direction, and the Y direction is the preset main light output direction; that is, the light output element 11 is the lamp glass. More specifically, the light output element 11 is a slender lamp glass. The lamp glass is the glass shell of the lamp assembly, and the corresponding lamp assembly is also slender. The structure of the slender lamp assembly will be described in detail below.

[0049] The light guide 13 is located within the receiving cavity 12, and its light-emitting surface is adjacent to the light-incident surface of the light-emitting component 11. The light source module 14 is located within the receiving cavity 12, and the light source module 14 and the light guide 13 are arranged sequentially along a first direction. The light-emitting surface of the light source module 14 faces the light guide 13, and the light source module 14 is used to receive electrical energy and emit light towards the light guide 13. That is, the light source module 14 is installed on the side of the light guide 13 (the side relative to the main light-emitting direction).

[0050] Specifically, for a slender and narrow light assembly, the light from the light source module 14 is not directed directly outwards, but rather along the first direction X (i.e., Figure 4The light source module 14 emits light horizontally along the long side of the light assembly, and the light is directed towards the light guide 13. After being guided by the light guide 13, the light emitting surface of the light guide 13 emits light towards the light emitting element 11, and then the light emitting element 11 emits light to the outside. The light emitted from the light source module undergoes total internal reflection inside the light guide 13 (which is made of a highly transparent optical-grade material, such as PMMA). This avoids the problem of the light source 142 being directly visible through the thin-walled light emitting element 11 when it is installed on the backlight side of the light assembly along the Y direction, achieving a flicker-free and uniform light emission effect with a softer illumination effect.

[0051] Reference Figure 4 In some embodiments, the surface of the light guide 13 away from the light emitter 11 is provided with an interference scattering structure 131, which is configured to receive light and reflect light toward the light emitter 11.

[0052] Inside the light guide 13, light propagates through total internal reflection. An interference scattering structure 131 is set on the back of the light guide 13 (i.e. the surface of the light guide 13 away from the light emitting element 11) to achieve the effect of breaking total internal reflection and diffusing light, thereby diffusing and distributing the light inside the light guide 13. When the diffused light is emitted, it can fully illuminate the entire light emitting surface.

[0053] Reference Figure 4 In some embodiments, the interference astigmatism structure 131 includes a plurality of striped patterns 1311, which are arranged at intervals along a first direction; the striped patterns 1311 are recessed toward the light-emitting surface, and the cross-section of the striped patterns 1311 is semi-circular.

[0054] In this embodiment, the geometric shape of the pattern (such as the included angle and the curvature of the inclined plane) is designed according to optical laws to control the direction of reflected and scattered light, causing it to propagate more towards the desired light-emitting surface. Therefore, the reflective pattern can control the direction of reflected light, guiding it more effectively to the light-emitting surface, rather than causing ineffective diffuse reflection within the light guide 13. This reduces the loss of light energy in multiple reflections, further improving light extraction efficiency and enhancing the brightness of the forward light emission. At the end closer to the light source module 14 (near end), where the light is strongest, the pattern can be designed to be sparser and smaller to reduce the amount of reflection and scattering, avoiding excessive brightness at the near end. At the end farther from the light source module 14 (far end), where the light is weaker, the pattern is designed to be denser and larger to enhance the scattering effect and actively "supplement the light." By specifically compensating for the light attenuation at the far end and suppressing excessive light at the near end, the overall uniformity of the light emission of the lamp group can be improved, eliminating the gradual effect of "near bright and far dark".

[0055] Several striped patterns 1311 along the first direction ( Figure 4 This is a three-dimensional view of the light guide 13. The length direction of the light guide 13 is also the X direction. (Comparison) Figure 1As can be seen, the light guide 13 has recesses arranged at intervals (with its length direction consistent with the first direction) and with a semi-circular cross-section. This is equivalent to setting convex mirrors inside the light guide 13, that is, setting up an array of several miniature directional convex mirrors, which have a light-diffusing effect. After the light enters the interior of the light guide 13, it is directed towards these convex surfaces. These convex surfaces change the direction of the light, causing the light to diverge towards the light-emitting surface inside the light guide 13, allowing more light to shine onto the light-emitting surface, which increases the brightness of the light-emitting surface of the light guide 13.

[0056] Reference Figure 4 In some embodiments, the diameter of the stripe pattern 1311 closer to the light source module is smaller than the diameter of the stripe pattern farther away from the light source module.

[0057] Specifically, along the first direction, the radius of the semi-circular arc-shaped cross-section of the striped pattern away from the light source module is R, and the radius of the semi-circular arc-shaped cross-section of the striped pattern close to the light source module is r, where R is greater than r.

[0058] For details, please refer to Figure 8 The semi-circular arc-shaped structure of the striped pattern is a tiny dimming structure, and its radius directly determines its ability to control light. A smaller radius means a smaller surface area, resulting in less light deflection (refraction or scattering), making it easier for light to reach farther points. A larger radius means a larger surface area, resulting in greater light deflection, and the scattered light can enhance the brightness at farther points. This means that from the end closer to the light source module to the end farther away, the semi-circular arc-shaped striped pattern enhances the light diffusion ability. Therefore, this changing striped pattern creates a gradual optical interface for the light guide.

[0059] Furthermore, the light angle distribution on the light-emitting surface of the light guide will change. Specifically, at the end closer to the light source, the small-radius semi-circular arc structure causes a small amount of light scattering, and the light easily propagates to the far end (which helps to reduce the brightness at the near end and increase the brightness at the far end); at the end farther from the light source, the large-radius semi-circular arc structure scatters a large amount of light, which helps to increase the brightness at the far end. Ultimately, this will make the light at the near and far ends of the entire light guide evenly distributed, and the light-emitting surface of the light guide will present a uniform lighting effect.

[0060] In some embodiments, the spacing between adjacent stripe patterns 1311 decreases along the first direction and gradually away from the light source module.

[0061] Specifically, refer to Figure 4 and Figure 6 , Figure 4The length direction of the light guide 13 is the X direction. These striped patterns 1311 are arranged sequentially at intervals in the light emission direction of the light source module 14. As the light propagates in the light guide 13, the illumination gradually weakens. By adjusting the spacing of these striped patterns 1311, light control can be achieved. For example, at the end closer to the light source module 14 (the end with stronger light), a wider spacing and narrower stripes can be set to reduce the amount of scattered light and avoid excessive brightness at the near end; at the end farther from the light source module 14 (the end with weaker light), a narrower spacing and wider stripes can be set to increase the amount of scattered light and actively supplement the light at the far end, thereby improving the brightness uniformity of the light-emitting surface of the light guide 13.

[0062] In this application, by adjusting the light intensity to be sparse in the front and dense in the back, the brightness of the entire light-emitting surface is made to be uniform, eliminating the light spots that are brighter near the front and darker far away.

[0063] Reference Figure 4 In some embodiments, the light-emitting surface of the light guide 13 is attached to the light-incident surface of the light-emitting component 11, and the light guide 13 and the light-emitting component 11 are integrally formed.

[0064] In this embodiment, the light-emitting surface of the light guide 13 and the light-incident surface of the light-emitting component 11 are made into complete and tight contact through physical means (such as optical adhesive OCA bonding, hot pressing fusion, etc.), which helps to eliminate the air gap in between. This allows light to propagate as if it were in the same medium when passing through the interface of the two components, achieving seamless light path transmission, greatly reducing reflection loss, and improving the overall brightness of the lamp assembly under the same light source power.

[0065] Furthermore, by adopting the configuration of this embodiment, the components used to support and fix the light guide 13 are eliminated, and the light guide 13 and the light emitting component 11 are modularized into a single part, which greatly simplifies the assembly process, reduces labor costs and working hours, and improves production efficiency. Since the components used to support and fix the light guide 13 are eliminated, the extra space used to install these components is saved, and the size of the lamp assembly can be further reduced, making it possible to install slender and narrow lamp assemblies.

[0066] Reference Figure 6 In some embodiments, along the main light output direction, the size of the light guide 13 at the end near the light source module 14 is larger than the size of the light guide 13 at the end away from the light source module 14.

[0067] Specifically, the size of the end of the light guide 13 near the light source module 14 is larger than the size of the end of the light guide 13 away from the light source module 14. That is, the thickness of the light guide 13 is not uniform. The end of the light guide 13 near the light source module 14 is thicker (the size along the first direction is the thickness of the light guide 13), and the end of the light guide 13 away from the light source module 14 is relatively thinner. Because the light guide 13 has strong light at the end closest to the light source module 14, the light guide 13 receiving strong light has a large thickness and a large cross-sectional area, which can carry and disperse the initial light, avoiding excessive brightness due to excessive light concentration; because the light guide 13 has weak light at the end furthest from the light source module 14, the light guide 13 receiving weak light has a small thickness and a small cross-sectional area. As light energy decays, the smaller volume helps maintain sufficient light energy density per unit volume, so that the far end can also extract light with brightness comparable to the near end (far end and near end refer to the distance between different parts of the light guide 13 and the light source module with the light source module as the reference), ensuring the uniformity of light emission from the light guide 13, improving the overall light efficiency, and making the lamp group brighter under the same power.

[0068] Reference Figure 5 , Figure 6 and Figure 7 In some embodiments, the light source module 14 includes a light source plate 141 and a power transmission component 143. A light source 142 is provided on the surface of the light source plate 141, with the light-emitting surface of the light source 142 facing the light guide component 13. One end of the power transmission component 143 is connected to the light source plate 141, and the other end is used to connect to an external connector 15 through a connection hole on the surface of the housing 10. Along a second direction, the end of the power transmission component 143 connected to the external connector 15 is closer to the housing 10 than the end connected to the light source plate 141. This second direction is opposite to the preset main light-emitting direction. Figure 7 The opposite direction of the Y-axis.

[0069] Specifically, along the second direction, the end of the power transmission component 143 that connects to the external plug is closer to the housing 10 than the end that connects to the light source board 141. This indicates that the power transmission component 143 can be connected to the external plug 15 in the forward direction (the forward direction here is the same as the main light output direction). When the lamp assembly is installed on the vehicle body, the external wiring harness is usually on the backlight side of the lamp assembly installation position. Configuring the power transmission component 143 to be arranged and connected to the external plug 15 in the forward direction is more in line with the assembly requirements.

[0070] In this embodiment, the power transmission component 143 can have three L-shaped pins. One end of the L-shaped pin is connected to the light source board 141 along a first direction, and the other end is electrically connected to an external connector along a second direction. Since the end of the L-shaped pin connected to the external connector 15 is arranged along the second direction, that is, along the second direction, the end of the power transmission component 143 connected to the external connector is closer to the housing 10 than the end connected to the light source board 141. Therefore, the lamp assembly is configured to be connected to the external connector 15 in the forward direction, which better meets the assembly requirements. Compared with soldering wires to the surface of the light source board 141, soldering the light source board 141 to the pins is more operable, facilitates production assembly and solder joint quality inspection, and effectively avoids the failure risk caused by wire pressing and pulling.

[0071] Reference Figure 5 and Figure 7 In some embodiments, the light source module 14 further includes an adapter bracket 144, which is T-shaped and includes: a horizontal plate portion 1441 connected to the side surface of the light source plate 141 away from the light source 142; and a vertical plate portion 1442 connected to the side surface of the horizontal plate portion 1441 away from the light source plate 141; the power transmission component 143 passes through the light source plate 141, the horizontal plate portion 1441 and the vertical plate portion 1442 in sequence, and is electrically connected to the external connector 15 after the vertical plate portion 1442 is bent in a second direction.

[0072] Specifically, the "T"-shaped structure forms a robust mounting frame. The horizontal plate 1441 is used to fix the light source plate 141, and the vertical plate 1442 forms the electrical connection surface. The light source plate 141 is fixed to the horizontal plate 1441 by screws or other means, thereby achieving rigid fixation and accurate positioning of the light source plate 141 and ensuring that its relative position with the light guide 13 remains unchanged. The power transmission component 143 bends in the second direction (i.e., the mounting direction of the lamp assembly) at the vertical plate 1442. This means that all electrical connections are guided and concentrated on a unified, easy-to-operate interface surface, which is perpendicular to the light source plate 141 and in the same mounting direction as the lamp assembly, suitable for docking with an external power source.

[0073] In addition, the adapter bracket 144 serves as a bridge connecting the vehicle body end and the light source board 141. The adapter bracket 144 is T-shaped and has three L-shaped pins embedded inside. It is injection molded by insert mold. One end of the pins goes through the light source board 141 and the other end is aligned with the plug-in port 102. The plug-in port 102 is used to connect the external plug-in 15. LED beads, capacitors, resistors and other electronic components are arranged on the light source board 141.

[0074] Since the pins are embedded in the adapter bracket 144 and pass through the light source board 141, the horizontal plate portion 1441 and the vertical plate portion 1442 in sequence, this is equivalent to providing a preset, protected channel for the pins, avoiding contact with or damage to the pins during assembly or use.

[0075] Reference Figure 5 In some embodiments, the horizontal plate portion 1441 is provided with at least two positioning posts 1443 on the side near the light source plate 141, and the light source plate 141 is provided with positioning holes 1411 corresponding to the positioning posts 1443. The positioning posts 1443 are installed in conjunction with the positioning holes 1411 to connect the adapter bracket 144 to the light source plate 141.

[0076] Specifically, the engagement of the positioning post 1443 and the positioning hole 1411 ensures that the adapter bracket 144 and the light source board 141 are in the correct position within plane C (plane C is parallel to the plane of the light source board 141 near the light guide 13) and in terms of rotation angle, avoiding installation errors. During installation, operators do not need to painstakingly align visually; they only need to align the positioning post 1443 with the positioning hole 1411 and place it down. The component will automatically position itself correctly, ensuring that the relative position of the light source board 141 and the adapter bracket 144 is consistent in every produced product. This significantly improves assembly speed and reduces the technical requirements and fatigue of operators.

[0077] Reference Figure 6 and Figure 7 In some embodiments, the housing 10 further includes a plug-in port 102 that extends through the housing 10 and has a plug-in direction consistent with the second direction. The plug-in port 102 is used to accommodate an external connector 15. The power transmission component 143 includes a plug-in portion 1431 that extends in the same direction as the second direction. The plug-in portion 1431 is inserted into the plug-in port 102 and connected to the external connector 15.

[0078] Specifically, the plug-in port 102 penetrates the housing 10, forming a protected channel directly from the outside to the inside. This provides a unique and accurate path for the external plug-in 15, guiding it directly to the internal mating point without deviation. Installers can complete the electrical connection with a simple alignment and insertion action, eliminating the need for any tools or complicated wiring, thus shortening installation time and greatly improving efficiency.

[0079] Reference Figure 6 and Figure 7In some embodiments, the housing 10 includes a plug-in port 102 that penetrates the housing 10. The light source module 14 is provided with a positioning boss 145 on the side facing the second direction. The positioning boss 145 is embedded in the plug-in port 102. The power transmission component 143 passes through the positioning boss 145 and extends into the plug-in port 102.

[0080] Specifically, the positioning boss 145 is embedded in the plug-in port 102. The positioning boss 145 can be used to limit the position of the light source module 14. The power transmission component 143 passes through the positioning boss 145 and extends into the plug-in port 102, ensuring that the plug-in part 1431 and the external plug-in 15 inside the plug-in port 102 are in the optimal docking position.

[0081] In some embodiments, the plug-in port 102 is provided with a locking buckle, which is located on the inner sidewall of the plug-in port 102 and has a groove structure; the external plug is provided with a locking female buckle, which is installed in conjunction with the locking buckle.

[0082] Specifically, when the external plug-in 15 is inserted into the plug-in port 102, the locking female buckle (usually an elastic barb or protrusion) on the external plug-in 15 will elastically deform with the locking male buckle (groove) on the inner wall of the port and quickly spring back and lock in. After locking is completed, a specific operation (such as pressing the release mechanism) is required to release it.

[0083] Reference Figure 3 In some embodiments, the inner sidewall of the housing 10 is provided with a positioning groove 101, and the light source module 14 is installed in the positioning groove 101.

[0084] Specifically, the positioning groove 101 restricts the position of the light source board 141 in the first direction. The positioning groove 101 acts as a guide rail during installation. The operator only needs to push the light source module 14 into the groove in the direction of the groove to easily reach the predetermined position without the need for complicated measurement and alignment. This greatly improves the assembly speed and reduces the technical requirements and fatigue of the operator.
