[0002] With the development of automotive technology, in-vehicle ambient lighting has gradually become one of the important features for enhancing the comfort and technological feel of the vehicle's interior environment.
[0003] However, current vehicle ambient lighting is mainly used for decorative purposes and has low practicality, especially in meeting the actual lighting needs of the vehicle interior. For lighting purposes, reading lights are used instead. This results in ambient lighting and reading lights being two separate, independent units that need to be installed independently, increasing the complexity and cost of the overall vehicle assembly structure. Furthermore, the separately installed reading lights lack a sense of technology and aesthetics. Utility Model Content
[0004] The problem this invention addresses is: how to reduce the complexity and cost of assembling in-vehicle lighting, and enhance the technological feel and aesthetics of in-vehicle lighting.
[0005] To solve the above problems, this utility model provides a vehicle-mounted lamp and a vehicle.
[0006] In a first aspect, this utility model provides a vehicle-mounted lamp, including a housing, a light-transmitting cover, an ambient light source assembly, a reading light source assembly, and a light guide. The housing is detachably connected to the vehicle body, and the light-transmitting cover is detachably connected to the housing. The housing and the light-transmitting cover together form a mounting cavity, and the light guide is disposed within the mounting cavity. The ambient light source assembly is disposed at a first end of the light guide, and the reading light source assembly is disposed at a second end of the reading light source assembly. The light guide is used to receive and propagate the light emitted by the ambient light source assembly or the light emitted by the ambient light source assembly.
[0007] Optionally, both the ambient light source component and the reading light source component include monochrome or multicolor LEDs, and the rated power of the reading light source component is greater than the rated power of the ambient light source component.

[0009] Optionally, the housing is provided with a snap-fit structure, and the light-transmitting mask is provided with a slot structure adapted to the snap-fit structure; or the housing is provided with a slot structure, and the light-transmitting mask is provided with a snap-fit structure adapted to the slot structure; the housing and the light-transmitting mask are engaged and fitted together by the snap-fit structure and the slot structure.
[0010] Optionally, the light-transmitting mask includes an integrally formed connecting portion and a light-transmitting portion, with the connecting portion arranged around the light-transmitting portion.

Those skilled in the art should understand that, unless explicitly stated otherwise in the context, they should be understood as "one or more".

[0026] Combination Figure 1 , Figure 4 As shown, this utility model embodiment provides a vehicle-mounted lamp, including a housing 1, a light-transmitting cover 2, an ambient light source component 3, a reading light source component 4, and a light guide 5. The housing 1 is detachably connected to the vehicle body, and the light-transmitting cover 2 is detachably connected to the housing 1. The housing 1 and the light-transmitting cover 2 together form a mounting cavity 6, and the light guide 5 is disposed within the mounting cavity 6. The ambient light source component 3 is disposed at the first end of the light guide 5, and the reading light source component 4 is disposed at the second end of the reading light source component 4. The light guide 5 is used to receive and propagate the light emitted by the ambient light source component 3 or the light emitted by the ambient light source component 3.
[0027] In this embodiment, the housing 1 of the vehicle-mounted lamp is detachably connected to the vehicle body via fasteners or snap-fit structures, enabling the installation of the vehicle-mounted lamp on the vehicle body and improving the convenience of installation and removal between the vehicle-mounted lamp and the vehicle body, thereby facilitating the maintenance or replacement of the vehicle-mounted lamp. The light-transmitting cover 2 is detachably connected to the housing 1 via fasteners or snap-fit structures, improving the convenience of installation and removal between the light-transmitting cover 2 and the housing 1. The light-transmitting cover 2 has a certain light transmittance in all or part of its area, facilitating light transmission; and the light-transmitting cover 2 can provide corresponding protection and covering for the vehicle-mounted lamp components located between itself and the housing 1, thereby improving the aesthetics of the vehicle-mounted lamp when installed on the vehicle body. The housing 1 and the light-transmitting cover 2 together form a mounting cavity 6 for accommodating the light guide 5, facilitating its installation. The light guide 5 can be fixed to the housing 1 via a detachable connection method such as snap-fit or adhesive bonding. This ensures stability when the light guide 5 is connected to the housing 1 while improving the ease of installation and removal of the light guide 5, thus enhancing the convenience of subsequent maintenance or replacement. The light guide 5 is used for the conduction and propagation of light. The ambient light source component 3 and the reading light source component 4 are respectively located at both ends of the light guide 5 (the end of the light guide 5 used to connect with the ambient light source component 3 is designated as the first end, and the end of the light guide 5 used to connect with the reading light source component 4 is designated as the second end). This allows the light emitted by the ambient light source component 3 or the reading light source component 4 to be transmitted and evenly distributed along the arrangement direction of the light guide 5, and then projected through the light-transmitting cover 2 into the vehicle interior where the vehicle lights are located, achieving an ambient lighting effect or a reading light effect. For example, when the ambient light source component 3 is working, the light emitted from the first end of the light guide 5 by the ambient light source component 3 propagates through the light guide 5. After being optimized by the optical structure (such as microstructure or reflective surface) inside the light guide 5, the light passes evenly through the light-transmitting mask 2, creating a soft and colorful light effect. When the reading light source component 4 is working, the bright light emitted from the second end of the light guide 5 by the reading light source component 4 propagates through the light guide 5 and passes evenly and relatively brightly through the light-transmitting mask 2 to meet the corresponding lighting needs inside the vehicle, such as reading or finding items. In some embodiments, the light guide 5 may be made of a material with high light transmittance and excellent optical properties (such as PMMA or PC). By designing microprism structures or optical textures inside, it can reflect, refract, or diffuse light of different wavelengths, thereby improving the uniformity and directionality of the light.
[0028] In this way, by installing vehicle-mounted lighting fixtures including a housing 1, a light-transmitting cover 2, an ambient light source component 3, a reading light source component 4, and a light guide 5, the ambient light source component 3 and the reading light source component 4 both emit light into the vehicle through the light guide 5 and the light-transmitting cover 2, achieving corresponding ambient lighting effects. This integrates the functions of vehicle ambient lighting and reading lights, avoiding the increased complexity and cost of the overall vehicle assembly structure caused by separately setting up the ambient lighting and reading lights. It effectively reduces the complexity and cost of interior lighting assembly and improves the convenience of subsequent maintenance. Furthermore, by combining the light guide 5 with the corresponding light source components, the transmission and propagation of light are achieved, making the light propagation more uniform, thereby improving the quality of the light and the overall visual effect inside the vehicle, enhancing the technological feel and aesthetics of the interior lighting. In addition, the ambient light source component 3 and the reading light source component 4 can be independently controlled according to user needs to meet personalized requirements.
[0029] Optionally, both the ambient light source component 3 and the reading light source component 4 include monochrome or multicolor LEDs, and the rated power of the reading light source component 4 is greater than the rated power of the ambient light source component 3.
[0030] In this embodiment, both the ambient light source component 3 and the reading light source component 4 include monochromatic or multicolor LEDs. This means that both components can emit monochromatic or multicolor light to meet diverse user needs. Furthermore, the rated power of the reading light source component 4 is greater than that of the ambient light source component 3, meaning the ambient light source component 3 has a lower rated power. This ensures that the ambient light from the ambient light source component 3 is relatively soft, preventing glare from the ambient light effect on occupants. The reading light source component 4 has a higher rated power to provide clear lighting (or reading light effect) when the user has specific lighting needs.
[0031] For example, the ambient light source component 3 can use monochrome or multi-color RGB LEDs. For instance, multi-color RGB LEDs, where each LED integrates red, green, and blue light chips, can achieve various color combinations through circuit control to meet personalized user needs. Users can choose different light colors according to their personal preferences or vehicle interior style to create a warm, technological, or other personalized in-car atmosphere. The reading light source component 4 uses high-brightness white LEDs, such as those using cool white light chips, to provide bright and clear lighting effects, meeting the needs of in-car reading, searching for items, or other scenarios requiring high-brightness illumination.
[0032] Optionally, the light guide 5 includes a first light guide and a second light guide, which are spaced apart in the mounting cavity 6 and both extend along the length of the mounting cavity; the first end of the first light guide is connected to the ambient light source assembly 3, and the second end of the second light guide is connected to the reading light source assembly 4.
[0033] In this embodiment, the ambient light source component 3 and the reading light source component 4 transmit light through the first light guide and the second light guide, respectively, to meet the ambient lighting effect and reading light effect in different areas. Both the first and second light guides are disposed within the mounting cavity 6 formed by the housing 1 and the light-transmitting cover 2. For example, considering factors such as the seating layout inside the vehicle and the impact on the driver's and passengers' vision, the placement and angle of the first and second light guides can be designed differently. For instance, based on the placement position of the housing 1, the first light guide can be positioned in an area suitable for creating ambient light within this base, achieving uniform and soft light illumination in these areas and enhancing the overall atmosphere inside the vehicle. The second light guide, according to the needs of the driver and passengers, can be positioned in an area within this base that requires high-brightness illumination, ensuring that the light effectively illuminates the desired position of the driver or passenger without causing negative effects (such as direct eye contact), providing clear reading or operational lighting effects. In some embodiments, the first light guide and the second light guide are spaced apart in the mounting cavity 6 to avoid mutual interference during installation and to prevent interference with the light guiding effect when the first light guide or the second light guide is working (guiding light). Moreover, the first light guide and the second light guide both extend along the length direction of the mounting cavity to be compatible with the light-transmitting mask 2 whose length direction is parallel to the length direction of the mounting cavity, so as to ensure the light effect when the vehicle lamp emits light and enhance the technological feel and aesthetics of the interior lighting.
[0034] Optionally, the housing 1 is provided with a plurality of mounting holes 11 for mounting fasteners (such as bolts, screws, etc.). The housing 1 is detachably connected to the vehicle body through the mounting holes 11 and fasteners, thereby improving the convenience of installing and removing the housing 1 on the vehicle body.
[0035] Optionally, the housing 1 is provided with a snap-fit structure 7, and the light-transmitting mask 2 is provided with a slot structure 8 adapted to the snap-fit structure 7, or the housing 1 is provided with a slot structure 8, and the light-transmitting mask 2 is provided with a snap-fit structure 7 adapted to the slot structure 8; the housing 1 and the light-transmitting mask 2 are engaged and fitted together by the snap-fit structure 7 and the slot structure 8.
[0036] In this embodiment, the housing 1 and the light-transmitting mask 2 are detachably connected through a snap-fit structure 7 and a slot structure 8. This improves the ease of installation and disassembly between the housing 1 and the light-transmitting mask 2 while maintaining the aesthetics of the vehicle lighting fixture. It avoids the need for drilling holes in the light-transmitting mask 2 when using fasteners for detachable connection, which would affect its appearance. To ensure ease of disassembly between the housing 1 and the light-transmitting mask 2, it is preferable that the housing 1 has one of the snap-fit structure 7 and the slot structure 8, and the light-transmitting mask 2 has the other of the snap-fit structure 7 and the slot structure 8. This avoids the increased difficulty of disassembly caused by simultaneously having both snap-fit structures 7 and slot structures 8 on either the housing 1 or the light-transmitting mask 2. Alternatively, the housing 1 may have a slot structure 8, and the light-transmitting mask 2 may have a snap-fit structure 7; or the housing 1 may have a snap-fit structure 7, and the light-transmitting mask 2 may have a slot structure 8.
[0037] For example, the housing 1 is provided with multiple slot structures 8, or the surface of the housing 1 and the vehicle body form a corresponding slot structure 8, and the light-transmitting mask 2 is provided with a buckle structure 7 that matches the slot structure 8; the buckle structure 7 on the light-transmitting mask 2 is adapted to the position and number of the corresponding slot structure 8 on the housing 1 to ensure that the housing 1 and the light-transmitting mask 2 are tightly and reliably connected.
[0038] Optionally, combined Figure 1 , Figure 4 As shown, the light-transmitting mask 2 includes an integrally formed connecting part 21 and a light-transmitting part 22, with the connecting part 21 arranged around the light-transmitting part 22.
[0039] In this embodiment, the light-transmitting mask 2 includes an integrally formed connecting portion 21 and a light-transmitting portion 22. The connecting portion 21 is arranged around the light-transmitting portion 22, that is, the light-transmitting portion 22 is located in the middle of the light-transmitting mask 2, and the connecting portion 21 is located at the edge of the light-transmitting mask 2. In other words, the edge portion of the light-transmitting mask 2 is the connecting portion 21, which is opaque or has low light transmittance, so as to block the edge connection between the light-transmitting mask 2 and the housing 1, thereby improving the aesthetics of the vehicle lighting fixture. The middle portion of the light-transmitting mask 2 is the light-transmitting portion 22, which has a certain light transmittance and is used for light output to meet the functional requirements of vehicle lighting fixtures or reading lights. Moreover, the connecting portion 21 and the light-transmitting portion 22 are integrally formed (such as injection molding) to improve the overall structural strength of the light-transmitting mask 2. In some embodiments, the light-transmitting mask 2 is made of two colors (such as different colors for the connecting portion 21 and the light-transmitting portion 22) or the middle portion is coated with light-transmitting paint, and the middle portion can transmit light as the light-emitting surface of ambient light and interior lighting.
[0040] Optionally, the housing 1 has a mounting groove 12 on the side facing the light-transmitting mask 2. The mounting groove 12 is positioned on the housing 1 and corresponds to the light-transmitting part 22 of the light-transmitting mask 2. On the one hand, the mounting groove 12 is used to position the light guide 5, ensuring that the light guide 5 corresponds to the light-transmitting part 22 of the light-transmitting mask 2, thereby ensuring the light effect when the vehicle lamp is lit and enhancing the technological feel and aesthetics of the interior lighting. On the other hand, the mounting groove 12 is used to limit the position of the light guide 5, ensuring the stability of the position of the light guide 5 on the housing 1 and the stability of the position of the light guide 5 in the mounting cavity 6 (the mounting groove 12 is located in the mounting cavity 6), ensuring the stability of the light beam when the vehicle lamp is lit and improving the user experience.
[0041] Optionally, combined Figure 1 , Figure 4 As shown, the edge of the connecting part 21 is provided with multiple spaced-apart snap-fit structures 7; the housing 1 is provided with multiple slot structures 8 at positions corresponding to the multiple snap-fit structures 7.
[0042] In this embodiment, the light-transmitting mask 2 has multiple spaced-apart snap-fit structures 7 at the edge of the connecting portion 21; the housing 1 has multiple slot structures 8 at positions corresponding to the multiple snap-fit structures 7. The snap-fit structures 7 and slot structures 8 engage to achieve a detachable connection between the light-transmitting mask 2 and the housing 1. For example, since the length direction of the light-transmitting mask 2 is parallel to or has a small angle with the length direction of the housing 1, it is preferable to provide multiple snap-fit structures 7 at the edge of the light-transmitting mask 2 in its width direction to ensure the stability of the connection between the light-transmitting mask 2 and the housing 1.
[0043] Optionally, the groove wall of the slot structure 8 is provided with a second guide slope 81, and the buckle structure 7 is provided with a first guide slope 71 that is adapted to the second guide slope 81 at the position corresponding to the second guide slope 81.
[0044] In this embodiment, to ensure that the housing 1 and the light-transmitting mask 2 can be smoothly engaged through the snap-fit structure 7 and the slot structure 8, a guide slope (denoted as the second guide slope 81) is provided on the slot wall of the slot structure 8. The second guide slope 81 extends at a certain angle at the entrance of the slot structure 8, and its function is to guide the snap-fit structure 7 to be smoothly inserted into the slot structure 8 during assembly, reducing the difficulty of engagement. At the position corresponding to the second guide slope 81, the snap-fit structure 7 is provided with a guide slope (denoted as the first guide slope 71) that is adapted to the second guide slope 81. For example, the first guide slope 71 is set at the end of the snap-fit structure 7 facing the slot structure 8 at the position corresponding to the second guide slope 81, and is designed at a certain angle at the end of the snap-fit structure 7 to ensure that it cooperates with the second guide slope 81 and the corresponding slot wall of the slot structure 8 during assembly, forming a natural transition, thereby reducing the snap-fit stress concentration and material fatigue caused by assembly pressure. The cooperation between the second guide slope 81 and the first guide slope 7 further reduces the difficulty of snapping together and significantly improves the assembly efficiency and stability between the housing 1 and the light-transmitting mask 2. The tilt angle of the guide slope is set according to actual needs.
[0045] For example, combined Figure 2 , Figure 3 As shown, the edge of the connecting part 21 is provided with multiple spaced buckle structures 7, and the housing 1 is provided with multiple slot structures 8 at positions corresponding to the multiple buckle structures 7; and the end of the buckle structure 7 away from the light-transmitting part 22 is provided with a first guide slope 71, and the slot structure 8 is provided with a second guide slope 81 that is adapted to the first guide slope 71 on the groove wall corresponding to the first guide slope 71.
[0046] In this embodiment, the end of the snap-fit structure 7 facing away from the light-transmitting part 22 is provided with a first guide slope 71. The first guide slope 71 is designed at a certain angle at the top of the snap-fit structure 7 to ensure that it cooperates with the corresponding groove wall of the slot structure 8 during assembly, forming a natural transition, thereby reducing snap-fit stress concentration and material fatigue caused by assembly pressure. Moreover, the groove wall of the slot structure 8 corresponding to the first guide slope 71 is provided with a second guide slope 81 adapted to the first guide slope 71. The second guide slope 81 extends at a certain angle at the entrance of the slot structure 8, and its function is to guide the snap-fit structure 7 to be smoothly inserted into the slot structure 8 during assembly. Through cooperation with the first guide slope 71, the snap-fit difficulty is further reduced. The inclination angle of the guide slope is set according to actual needs. Through the cooperative design of these guide slopes, the assembly efficiency and stability between the housing 1 and the light-transmitting mask 2 are significantly improved.
[0047] Optionally, the slot structure 8 has a second guide slope 81 on at least one of its slot walls, and the buckle structure 7 has a first guide slope 71 adapted to the second guide slope 81 at a position corresponding to the at least one second guide slope 81 of the slot structure 8.
[0048] In this embodiment, considering that the slot structure 8 generally has multiple slot walls, such as a rectangular hole-shaped slot structure with four slot walls, the slot structure 8 can have a second guide slope 81 set on any one slot wall, or a second guide slope 81 set on multiple slot walls simultaneously. Correspondingly, the snap-fit structure 7 has a first guide slope 71 adapted to the second guide slope 81 at a position corresponding to at least one second guide slope 81 of the slot structure 8. That is, the snap-fit structure 7 can have only one first guide slope 71 adapted to the corresponding second guide slope 81, or multiple first guide slopes 71 adapted to different second guide slopes 81 respectively. Through the cooperation of the first guide slope 71 and the second guide slope 81, the snap-fit difficulty between the slot structure 8 and the snap-fit structure 7 is reduced, ensuring that the housing 1 and the light-transmitting mask 2 can be smoothly snapped together through the snap-fit structure 7 and the slot structure 8, significantly improving the assembly efficiency and stability between the housing 1 and the light-transmitting mask 2.
[0049] Optionally, the light transmittance of the light-transmitting portion 22 is greater than a first preset value and less than a second preset value.
[0050] In this embodiment, the light transmittance of the light-transmitting portion 22 is designed between a first preset value and a second preset value to meet the corresponding light transmission requirements while avoiding excessively high light transmittance that would expose the internal components of the vehicle lighting fixture (which would be unsightly). For example, the first preset value is the lowest light transmittance that the light-transmitting portion 22 can adopt, ensuring that the light transmitted by the light guide 5 can pass smoothly through the light-transmitting portion 22 to achieve uniform interior lighting or ambient lighting effects. For example, the first preset value can be set to 60%. The second preset value is the highest light transmittance that the light-transmitting portion 22 can adopt, to avoid excessively high light transmittance that would expose the internal components of the vehicle lighting fixture, resulting in an unsightly appearance. For example, the second preset value can be set to 90%.
[0051] Optionally, the vehicle lighting also includes a first lighting control mechanism and a second lighting control mechanism, with the ambient light source component 3 communicatively connected to the first lighting control mechanism and the reading light source component 4 communicatively connected to the second lighting control mechanism.
[0052] In this embodiment, a first lighting control mechanism and a second lighting control mechanism are respectively connected to the ambient light source component 3 and the reading light source component 4 to achieve independent control of different light source components, thereby meeting the lighting needs of multiple scenarios inside the vehicle. The first lighting control mechanism is connected to the ambient light source component 3 to independently control its operating state. In some embodiments, users can send commands to the first lighting control mechanism via the vehicle's central control screen, physical buttons, or voice control module to control the ambient light source component 3, including on / off control, brightness adjustment, and color selection. The second lighting control mechanism is connected to the reading light source component 4 to independently control its operating state. In some embodiments, users can control the reading light's on / off state and brightness adjustment using similar methods. Furthermore, the ambient light source component 3 and the reading light source component 4 can be powered by different power supply lines.
[0053] Another embodiment of this utility model provides a vehicle including the above-described vehicle-mounted lighting fixture.
[0054] In this embodiment, the vehicle uses the aforementioned vehicle-mounted lighting fixtures to achieve corresponding ambient lighting or reading light effects. Specifically, by installing vehicle-mounted lighting fixtures on the vehicle, including a housing 1, a light-transmitting cover 2, an ambient light source component 3, a reading light source component 4, and a light guide 5, on the one hand, both the ambient light source component 3 and the reading light source component 4 emit light into the vehicle through the light guide 5 and the light-transmitting cover 2, achieving corresponding ambient lighting effects. This integrates the functions of vehicle ambient lighting and reading lights, avoiding the problem of increasing the complexity and cost of the overall vehicle assembly structure due to separate independent settings for vehicle ambient lighting and reading lights. This effectively reduces the complexity and cost of interior lighting assembly and improves the convenience of subsequent maintenance. On the other hand, by combining the light guide 5 with the corresponding light source component, the transmission and propagation of light are achieved, making the light propagation more uniform, thereby improving the quality of the light and the overall visual effect inside the vehicle, enhancing the technological feel and aesthetics of the interior lighting. In addition, the ambient light source component 3 and the reading light source component 4 can be independently controlled according to user needs to meet personalized user requirements.
[0055] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
