Vehicle light and vehicle

Abstract

The application provides a vehicle lamp and a vehicle. The vehicle lamp comprises a light source assembly and a light homogenizing piece. The light source assembly comprises a first light source and a second light source. The light homogenizing piece is arranged at a distance from the light source assembly and is used to receive and diffuse the light rays emitted by the light source assembly. The light rays emitted by the first light source and the second light source are different in angle. The light homogenizing piece and the width direction of the vehicle form an included angle greater than 0 degrees. The vehicle lamp of the application utilizes the light rays emitted by the first light source and the second light source and diffuses the light rays uniformly towards the rear of the vehicle through the light homogenizing piece, thereby improving the optical uniformity of the vehicle lamp and making it impossible to directly observe the light source bright spot when observing the vehicle lamp from the outside, and improving the aesthetic appearance. In addition, the light homogenizing piece and the width direction of the vehicle form an included angle greater than 0 degrees. That is, the light rays emitted by the light homogenizing piece can not only cover the area directly behind the vehicle tail but also cover part of the angle on the side of the vehicle tail, thereby realizing the design of a large-angle vehicle lamp.

This design reduces the assembly space requirements of the vehicle lamp and has the characteristics of being lightweight and low-cost.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this application. Attached Figure Description

[0020] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0022] like Figure 1 As shown, the vehicle 100 of this application includes a headlight 1, which is disposed at the rear of the vehicle 100.

[0023] In this application, the headlight 1 is located at the rear of the vehicle 100, thereby providing driving information, such as deceleration and emergency braking, to other drivers behind and diagonally behind the vehicle 100. This design can improve the safety of the vehicle 100 during operation and also provide more comprehensive driving information to other drivers behind the vehicle 100.

[0024] Combination Figure 1 and Figure 2 As shown, the vehicle headlight 1 of this application includes a light source assembly 11 and a light diffuser 12. The light source assembly 11 includes a first light source 111 and a second light source 112. The light diffuser 12 is disposed at a distance from the light source assembly 11 and is used to receive and diffuse the emitted light from the light source assembly 11. The emitted light angles of the first light source 111 and the second light source 112 are different. The light diffuser 12 has an angle A greater than 0 degrees with the width direction Y of the vehicle 100.

[0025] The headlight 1 of this application utilizes the first light source 111 and the second light source 112 to emit light, and the light is evenly diffused towards the rear of the vehicle 100 by the light diffuser 12, thereby improving the optical uniformity of the headlight 1. This also prevents the light source from being directly visible when the headlight 1 is viewed from the outside, enhancing its aesthetics. Furthermore, since the light diffuser 12 has an angle A greater than 0 degrees with the width direction Y of the vehicle 100, the light emitted from the light diffuser 12 can cover not only the area directly behind the rear of the vehicle but also a portion of the rear side angle, thus enabling a large-angle design for the headlight 1. Therefore, the design of the headlight 1 in this application ensures the optical uniformity of the headlight 1's function and achieves a large-angle headlight 1's brightness effect without requiring a large number of light sources, internal mirrors, thick-walled light guides, or other structures. This design reduces the assembly space requirements of the headlight 1 and features lightweight and low-cost characteristics.

[0026] In an optional embodiment, the light-diffusing element 12 is made of polycarbonate material or polymethyl methacrylate material.

[0027] Depending on the different application scenarios and usage requirements of the vehicle 100, different materials can be selected for the light-diffusing element 12. For example, the light-diffusing element 12 made of polycarbonate material has excellent transparency, high impact strength, and good heat resistance, and can adapt to higher operating temperatures; while the light-diffusing element 12 made of polymethyl methacrylate material has higher light transmittance, lower density, and better processing performance, making it more suitable for fine processing scenarios. Therefore, this application does not impose any limitations on this.

[0028] In an optional embodiment, a light-diffusing layer, such as an organosilicon light-diffusing agent, can be added to the surface of the light-diffusing element 12. This design can increase the haze value of the light-diffusing element 12. Specifically, in the embodiments provided in this application, when the measured thickness of the light-diffusing element 12 is set to 4 mm, its haze value is in the range of 7% to 30%, thereby enabling the light-diffusing element 12 to exhibit a light-transmitting but not transparent diffused light effect.

[0029] In an optional embodiment, the vehicle headlight 1 further includes a circuit board 13, the light source assembly 11 is electrically connected to the circuit board 13, and the first light source 111 and the second light source 112 are both attached to the circuit board 13.

[0030] The vehicle headlight 1 of this application has the first light source 111 and the second light source 112 directly mounted on the circuit board 13, which not only simplifies the assembly process of the vehicle headlight 1, but also reduces its assembly space requirements and lowers the assembly difficulty.

[0031] In an optional embodiment, the first light source 111 is a vertically mounted LED light source, and the second light source 112 is a flat-mounted LED light source. Specifically, as... Figure 3As shown, the light-emitting surface of the first light source 111 is parallel to the length direction X, and the light-emitting surface of the second light source 112 is parallel to the width direction Y. The length direction X is perpendicular to the width direction Y.

[0032] The vehicle headlight 1 of this application uses a vertically mounted LED as the first light source 111 and a flat-mounted LED as the second light source 112. The light-emitting surface of the first light source 111 is designed to be parallel to the length direction X, and the light-emitting surface of the second light source 112 is designed to be parallel to the width direction Y. This design ensures that the light emitted from the first light source 111 ( Figure 3 (As shown by the red dashed line) can cover the light path region in the length direction X, while the light emitted from the second light source 112 ( Figure 3 (As shown by the blue dashed line) can cover the optical path area in the width direction Y, thereby presenting a larger light surface on the light diffuser 12, so that the light emitted from the light diffuser 12 ( Figure 3 (As shown by the yellow arrow in the middle) More uniform and with wider coverage. In this way, not only is a large-angle design of headlight 1 achieved, but its uniformity is also ensured, effectively improving the overall aesthetics and safety of headlight 1, and also providing a better driving experience for other drivers behind vehicle 100.

[0033] Of course, in other alternative embodiments, depending on the specific usage scenario, assembly space, overall appearance, and user needs of different vehicles 100, the first light source 111 can be designed as a flat-mounted LED light source, and the second light source 112 can be designed as a vertical-mounted LED light source; or both the first light source 111 and the second light source 112 can be designed as flat-mounted LED light sources; or both the first light source 111 and the second light source 112 can be designed as vertical-mounted LED light sources; or other light source structures can be used to emit light. Therefore, this application does not impose any limitations on this.

[0034] In an optional embodiment, the circuit board 13 is arranged parallel to the length direction X of the vehicle 100, and the first light source 111 and the second light source 112 are spaced apart in the length direction X.

[0035] The vehicle headlight 1 of this application has a first light source 111 and a second light source 112 spaced apart in the length direction X, so that the light emitted by the light source assembly 11 can cover a wider angle range, thereby improving the uniformity of the light path of the vehicle headlight 1 and avoiding the situation where some areas are too bright and some areas are too dark.

[0036] Of course, in other alternative embodiments, the flush arrangement described in this application may not be adopted. Instead, the first light source 111 and the second light source 112 may be arranged in an alternating manner according to the specific usage scenario, assembly space, overall appearance, and user needs of different vehicles 100. For example, they may be staggered in the height direction of the vehicle 100, with one light source higher and the other lower. Alternatively, the circuit board 13 structure connected to one of the light sources may be raised, so that the two light sources are staggered in the width direction Y. Or, in the scheme described above, flat-mounted LED light sources and vertical-mounted LED light sources may be used as light source components 11, and the design positions of the flat-mounted LED light sources and vertical-mounted LED light sources may be arranged in an alternating manner according to the actual usage scenario. For example, the installation position of the flat-mounted LED light source in the height direction may be raised, or the circuit board 13 structure connected to the vertical-mounted LED light source may be raised, etc., thereby meeting more complex optical path requirements. Therefore, this application does not limit the arrangement scheme of the light source component 11.

[0037] In an optional embodiment, the distance between the first light source 111 and the second light source 112 along the length X of the vehicle 100 is greater than or equal to 4 mm and less than or equal to 20 mm. This design ensures that the emitted light from the light source assembly 11 covers a sufficient angle, guaranteeing the uniformity of the headlight 1. At the same time, it avoids the situation where the distance between the first light source 111 and the second light source 112 is too large, causing some light to fail to enter the light diffuser 12.

[0038] Specifically, depending on the specific usage scenario, assembly space, overall appearance, and user needs of different vehicles 100, the distance between the first light source 111 and the second light source 112 can be designed to be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm, and this application does not impose any restrictions on this.

[0039] In an optional embodiment, the headlight 1 further includes a support member 14, arranged along the length direction X of the vehicle 100 and located on the side of the circuit board 13 opposite to the light source assembly 11. The support member 14 is used for connection to the vehicle 100. The circuit board 13 is attached to the side of the support member 14 opposite to the vehicle 100.

[0040] The vehicle headlight 1 of this application effectively improves the stability of the circuit board 13 through the design of the support member 14, thereby ensuring the stability of the emitted light from the light source assembly 11. This makes the light path presented by the headlight 1 more stable during the actual operation of the vehicle 100, thus ensuring the stability and safety of the vehicle 100 during operation.

[0041] In an optional embodiment, the support member 14 extends at both ends along the length direction X in mutually distant directions and extends beyond the circuit board 13. At least a portion of the emitted light from the light source assembly 11 is reflected by the support member 14 to the light diffuser 12.

[0042] from Figure 3 As can be seen, part of the light emitted from the first light source 111 (shown by the red dotted line in the figure) directly enters the light diffuser 12, while another part is reflected into the light diffuser 12 through the support member 14. This design ensures that the light from the light source is fully utilized, further ensuring that the light diffuser 12 receives sufficient light, thereby improving the working performance of the vehicle lamp 1. At the same time, the extended design of the support member 14 also improves its enclosure of the circuit board 13, improving the stability of the connection of the circuit board 13, thereby ensuring the safety of the vehicle 100 during operation.

[0043] In an optional embodiment, the support member 14 of this application may be made of white polycarbonate material, or aluminum may be plated on the surface of the support member 14 to enhance the reflective effect of the support member 14.

[0044] In an optional embodiment, the shortest distance between the first light source 111 and the second light source 112 and the light diffuser 12 is greater than or equal to 20 mm and less than or equal to 60 mm.

[0045] Since the light source assembly 11 of this application includes both flat-mounted LED light sources and vertical-mounted LED light sources, the distance design between the first light source 111 and the second light source 112 and the light diffuser 12 can ensure that there is sufficient reflection space between the light diffuser 12 and the light source, thereby ensuring that the light diffuser 12 receives sufficient light; at the same time, it can also avoid the situation where the distance between the light source and the light diffuser 12 is too far, resulting in some light not being able to enter the light diffuser 12.

[0046] Specifically, depending on the specific usage scenario, assembly space, overall appearance, and user needs of different vehicles 100, the distance between the first light source 111 and the light diffuser 12 can be designed to be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, or 60mm; similarly, the distance between the second light source 112 and the light diffuser 12 can also be designed to be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, or 60mm. Furthermore, it should be noted that in different embodiments, the distances between the first light source 111 and the second light source 112 and the light diffuser 12 can be the same, for example, […]. Figure 2 The connection point between the second light source 112 and the circuit board 13 shown is thickened to shorten the distance between the second light source 112 and the light diffuser 12; or it can be directly adopted as shown in the figure. Figure 2The illustrated scheme designs different spacings between the first light source 111, the second light source 112, and the light diffuser 12, thereby achieving different lighting effects and meeting different requirements. Therefore, this application does not impose any limitations on this.

[0047] Overall, during the actual operation of the vehicle 100, when the circuit board 13 is powered on, the first light source 111 and the second light source 112 will emit light beams respectively. Part of the light beam can directly enter the light-diffusing element 12 and be fully refracted in the light-diffusing element 12. The other part of the light beam is refracted by the support member 14 and then enters the light-diffusing element 12, acting as supplementary lighting, so that the light beam can be fully utilized, thereby improving the uniformity of the headlight 1.

[0048] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
