Description

Technical Field

[0001] This technology relates to the field of automotive lighting technology, and in particular to a light distribution component and a lamp. 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 fixtures with a slender and narrow body, if the light source is placed directly on the backlight side away from the light-emitting surface, the light will pass directly through the thin-walled light-transmitting component, producing obvious glare and uneven light output. Moreover, such light fixtures have a unique shape, occupy a lot of vehicle space, and are more difficult to install. Utility Model Content

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

[0004] This application provides a light distribution component, including:

[0005] An optical transmission section, wherein one end of the optical transmission section along a first direction is an input end, and the optical transmission section has an output surface;

[0006] The light-emitting part has a dimension along a first direction that is larger than its dimension along other directions; the light-incident surface of the light-emitting part is in contact with the light-emitting surface of the light transmission part, and is used to receive the light emitted by the light transmission part and emit the light along a preset main light-emitting direction, wherein the first direction intersects with the preset main light-emitting direction.

[0007] In one embodiment, the surface of the light transmission section away from the light emission section is provided with an interference scattering structure, the interference scattering structure including a plurality of striped patterns, the striped patterns being arranged at intervals along a first direction;

[0008] The striped pattern is recessed towards the light-emitting surface of the light transmission section, and the cross-section of the striped pattern is semi-circular.

[0009] In one embodiment, 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.

[0010] In one embodiment, the spacing between adjacent stripes decreases as the light source module moves away from the first direction.

[0011] In one embodiment, along the main light output direction, the dimension of the light transmission section near the light input end is greater than the dimension of the light transmission section away from the light input end.

[0012] In one embodiment, the light transmission unit and the light emission unit are integrally disposed.

[0013] A lighting fixture includes the aforementioned light distribution component, and further includes a housing connected to the light distribution component, wherein a receiving cavity for accommodating a light source module is formed between the light distribution component and the housing.

[0014] In one embodiment, the light source module and the light transmission unit are arranged sequentially along a first direction, and the light source module is used to receive electrical energy and emit light toward the light transmission unit; the light source module includes:

[0015] A light source board, the surface of which is provided with a light source, the light emitting surface of which faces the light incident end of the light transmission section;

[0016] A power transmission component, one end of which is connected to the light source board, and the other end of which is used to connect to an external connector wire through a connection hole on the surface of the housing; in the second direction, the end of the power transmission component connected to the external connector is closer to the housing than the end connected to the light source board, and the second direction is opposite to the preset main light output direction.

[0017] In one embodiment, the light source module further includes an adapter bracket, the adapter bracket being T-shaped, and the adapter bracket comprising:

[0018] The horizontal plate portion is connected to the surface of the light source plate away from the light source; and

[0019] 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.

[0020] In one embodiment, the housing includes a plug-in port that extends through the housing, the plug-in port having a plug-in direction consistent with a second direction, and the plug-in port being used to accommodate an external plug-in.

[0021] The power transmission component includes a plug-in portion, the extension direction of which is the same as the second direction, and the plug-in portion is connected to an external connector.

[0022] or,

[0023] The housing includes a plug-in port that penetrates the housing. The light source module has a positioning boss on one side near the housing. The positioning boss is embedded in the plug-in port. The power transmission component passes through the positioning boss and extends into the plug-in port.

[0024] The aforementioned light distribution components have at least the following beneficial technical effects:

[0025] The light-emitting surface of the light transmission unit emits light from the light-emitting section, which then directs the light to the outside. The light-incident end of the light transmission unit is located on one side, avoiding the problem of the light source being directly visible through the thin-walled light-emitting section when the light source is installed on the backlight side of the lamp. This achieves a flicker-free, uniform light emission effect and a softer illumination. Furthermore, the light-emitting surface of the light transmission unit is flush with the light-incident surface of the light-emitting section, eliminating the air gap in between. This allows the light to propagate as if it were in the same medium when passing through the interface between the two components, achieving seamless light path transmission and greatly reducing refraction loss.

[0026] This application employs a side-mounted light source module, reducing the installation gap between the luminaire and the vehicle body, thus minimizing space occupation. Modularizing the light transmission and emission sections into a single light distribution component greatly simplifies the assembly process, reduces labor costs and time, and improves production efficiency. By eliminating the components used to support and fix the light transmission section, additional space is saved for installing these components, allowing for further reduction in luminaire size and enabling the installation of slender and compact luminaires.

[0051] Reference Figures 1-2 A light distribution component, comprising:

[0052] The optical transmission unit 13 has an incident light end at one end along a first direction and has an exit light surface connected to the incident light end.

[0053] The light-emitting part 11 has a larger dimension along the first direction than along other directions; the light-incident surface of the light-emitting part 11 is in contact with the light-emitting surface of the light transmission part 13, and is used to receive the light emitted by the light transmission part 13 and emit the light along a preset main light-emitting direction, wherein the first direction intersects with the preset main light-emitting direction.

[0054] In this embodiment, the dimension of the light-emitting part 11 along the first direction is larger than its dimension along other directions. The light-emitting part 11 is used to receive and emit light rays along a preset main light-emitting direction (Y direction). The first direction intersects with the preset main light-emitting direction. Figures 1-3 The X direction is the primary direction, and the Y direction is the preset main light-emitting direction. More specifically, the light-emitting part 11 is a slender light-transmitting structure, and the corresponding lamp is also slender.

[0055] The light-emitting surface of the light transmission section 13 is adjacent to the light-incident surface of the light-emitting section 11; one end of the light transmission section along the first direction is the light-incident end, that is, the light source module 14 for emitting light and the light transmission section 13 are arranged sequentially along the first direction, and the light-emitting surface of the light source module 14 faces the light transmission section 13, that is, the light source module 14 is installed on the side of the light transmission section 13 (the side is relative to the main light-emitting direction).

[0056] Specifically, for slender and narrow lamps, the light from the light source module 14 is not directed directly to the outside, but rather along the first direction X (i.e., Figure 1 The light source module 14 emits light horizontally along the length direction of the light distribution component, and the light source module 14 emits light towards the light transmission section 13. After being transmitted by the light transmission section 13, the light emitting surface of the light transmission section 13 emits light towards the light emitting section 11, and the light emitting section 11 emits light to the outside. This avoids the problem that when the light source is installed on the backlight side of the lamp along the Y direction, the light source can be seen directly through the thin-walled light emitting section 11. This achieves a flicker-free and uniform light emission effect, and the illumination effect is softer.

[0057] Furthermore, in this embodiment, the light-emitting surface of the light transmission unit 13 is attached to the light-incident surface of the light-emitting unit 11, and the light transmission unit 13 and the light-emitting unit 11 are preferably integrally formed. By using physical methods (such as optical adhesive OCA bonding, thermoforming, etc.) to ensure complete and tight contact between the light-emitting surface of the light transmission unit 13 and the light-incident surface of the light-emitting unit 11, it is beneficial to eliminate the air gap in between. This allows light to propagate as if in the same medium when passing through the interface of the two components, achieving seamless light path transmission, greatly reducing refraction loss, and improving the overall brightness of the lamp at the same light source power.

[0058] Furthermore, by adopting the configuration of this embodiment, the components used to support and fix the light transmission section 13 are eliminated, and the light transmission section 13 and the light output section 11 are modularized into a single light distribution component, which greatly simplifies the assembly process, reduces labor costs and time, and improves production efficiency. Since the components used to support and fix the light transmission section 13 are eliminated, the extra space used to install these components is saved, and the size of the luminaire can be further reduced, making it possible to install slender and narrow luminaires.

[0059] Reference Figure 1 In some embodiments, the surface of the light transmission section 13 away from the light emission section 11 is provided with an interference scattering structure 131, which is configured to receive light and adjust the light toward the light emission section 11.

[0060] Inside the light transmission section 13, light propagates through total internal reflection. An interference scattering structure 131 is provided on the back side of the light transmission section 13 (i.e. the surface of the light transmission section 13 away from the light emitting section 11) to achieve the effect of breaking total internal reflection and diffusing light, thereby diffusing and distributing light inside the light transmission section 13. When the diffused light is emitted, the light emitting surface can be fully illuminated.

[0061] Reference Figure 1 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.

[0062] 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 instead of ineffective diffuse reflection within the light transmission section 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 lamp's light emission can be improved, eliminating the gradual effect of "near bright and far dark."

[0063] Several striped patterns 1311 along the first direction ( Figure 1 This is a perspective view of the optical transmission unit 13. The length direction of the optical transmission unit 13 is also the X direction. (Comparison) Figure 1The recesses (with their length direction aligned with the first direction) of the light transmission section 13, arranged at intervals and having a semi-circular cross-section, are equivalent to convex mirrors inside the light transmission section 13, i.e., an array of miniature directional convex mirrors, which diffuse the light. After the light enters the light transmission section 13, it strikes these convex surfaces, which change the direction of the light, causing it to diverge towards the light-emitting surface inside the light transmission section 13, thus increasing the brightness of the light-emitting surface of the light transmission section 13.

[0064] Reference Figures 1-2 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.

[0065] 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.

[0066] For details, please refer to Figure 2 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 travel to distant points. A larger radius means a larger surface area, resulting in greater light deflection, and the scattered light can enhance the brightness at distant 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 transmission section.

[0067] Furthermore, the light angle distribution on the light-emitting surface of the light transmission section 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, making it easier for the light to propagate to the far end (which helps 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 distribution at the near and far ends of the entire light transmission section uniform, and the light-emitting surface of the light transmission section will exhibit a uniform lighting effect.

[0068] In some embodiments, the spacing between adjacent stripe patterns 1311 decreases along the first direction and gradually away from the light source module.

[0069] Specifically, Figure 1The length direction of the light transmission section 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 transmission section 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 transmission section 13.

[0070] 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.

[0071] Reference Figure 1 and Figure 2 In some embodiments, along the main light output direction, the thickness of the light transmission section 13 at the end near the light source module 14 is greater than the thickness of the light transmission section 13 at the end away from the light source module 14.

[0072] Specifically, the size of the end of the light transmission section 13 near the light source module 14 is larger than the size of the end of the light transmission section 13 away from the light source module 14. That is, the thickness of the light transmission section 13 is not uniform. The end of the light transmission section 13 near the light source module 14 is thicker (the size along the first direction is the thickness size of the light transmission section 13), and the end of the light element away from the light source module 14 is relatively thinner. Because the light source module 14 has strong light at the end of the light transmission section 13, the thickness and cross-sectional area of ​​the light transmission section 13 receiving strong light are large, which can carry and disperse the initial light, avoiding excessive brightness due to excessive light concentration; because the light source module 14 has weak light at the end of the light transmission section 13, the thickness and cross-sectional area of ​​the light transmission section 13 receiving weak light are small. As light energy decays, the smaller volume helps to maintain sufficient light energy density per unit volume, so that light of comparable brightness to that of the near end can be extracted at the far end (far end and near end refer to the distance between different parts of the light transmission section 13 and the light source module with the light source module as the reference), ensuring the uniformity of light emission from the light transmission section 13, improving the overall light efficiency, and making the lamp brighter at the same power.

[0073] Reference Figures 3-6 In some embodiments, a luminaire is provided, including a housing 10, a light distribution component, and a light source module 14. The housing 10 is connected to the light distribution component, and a receiving cavity is formed between the light distribution component and the housing 10.

[0074] Specifically, the light-emitting part 11 of the light distribution component is connected to the housing 10, and a receiving cavity 12 is formed between the light distribution component and the housing 10. The receiving cavity 12 provides installation space for the light source module 14 and isolates the light transmission part 13 and the light source module 14 from the external environment, thus playing a protective role.

[0075] The light source module 14 is located inside the receiving cavity 12. The light source module 14 and the light transmission unit 13 are arranged sequentially along the first direction. The light emitting surface of the light source module 14 faces the light transmission unit 13. The light source module 14 is used to receive electrical energy and emit light towards the light transmission unit 13. That is, the light source module 14 is installed on the side of the light transmission unit 13 (the side relative to the main light emission direction).

[0076] Specifically, for slender and narrow lamps, the light from the light source module 14 is not directed directly to the outside, but rather along the first direction X (i.e., Figure 5 The light source module 14 emits light horizontally along the long side of the luminaire, and the light is transmitted to the light transmission section 13. After being conducted by the light transmission section 13, the light emitting surface of the light transmission section 13 emits light to the light emitting section 11, and then the light is emitted to the outside. The light emitted by the light source module undergoes total internal reflection inside the light transmission section 13 (which is made of a highly transparent optical-grade material, such as PMMA). This avoids the problem that the light source 142 would be directly visible through the thin-walled light emitting section 11 when it is installed on the backlight side of the luminaire along the Y direction, thus achieving a flicker-free and uniform light emission effect and a softer illumination effect.

[0077] When the light source module 14 is located at the light input end of the light transmission section 13, the arrangement of the wiring harness connectors for the light source module 14 is more difficult due to the narrow space between the lamp and the surrounding sheet metal. (Refer to...) Figures 5-8 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 transmission section 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 emission direction. Figure 8 The opposite direction of the Y-axis.

[0078] 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 is installed on the vehicle body, the external wiring harness is usually on the backlight side of the lamp 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.

[0079] 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 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.

[0080] Reference Figure 8 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.

[0081] Specifically, the "T"-shaped structure forms a robust mounting frame. The horizontal plate 1441 is used to fix the light source board 141, and the vertical plate 1442 forms the electrical connection surface. The light source board 141 is fixed to the horizontal plate 1441 by screws or other means, thereby achieving rigid fixation and accurate positioning of the light source board 141 and ensuring that its relative position with the light transmission unit 13 remains unchanged. The power transmission unit 143 bends in the second direction (i.e., the mounting direction of the lamp) 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 board 141 and in the same direction as the lamp mounting, suitable for docking with an external power source.

[0082] 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.

[0083] 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.

[0084] Reference Figure 6 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.

[0085] 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 transmission section 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.

[0086] Reference Figure 7 and Figure 8 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.

[0087] 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.

[0088] Reference Figure 7 and Figure 8 In 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] Reference Figure 5 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.

[0093] 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.
