Technical Field

[0001] This application relates to the field of vehicle lighting technology, specifically to an optical component, vehicle lighting fixtures, and a vehicle. Background Technology

[0002] With the rapid development of vehicle electrification, intelligence, and connectivity, consumers are paying increasing attention to traffic safety and the intelligent interactive functions of vehicles. Pixelated intelligent lights (ISD), which feature multiple safety warning patterns and signal interaction functions and can achieve rich personalized animation effects, are one of the key development trends of vehicle traffic lights and have already been mass-produced in many models.

[0003] As vehicle exteriors become increasingly streamlined and aesthetically pleasing, the angle between the light-emitting surface of vehicle signal lights and the vehicle's direction of travel also increases. However, the current signal lights are positioned too low, hindering the improvement of pixel brightness and negatively impacting their wider application and vehicle safety. Utility Model Content

[0004] The purpose of this application is to provide an optical component, vehicle lighting fixture, and vehicle that can improve the utilization rate of the light beam and increase the brightness of the lighting pixels.

[0005] In one aspect of this application, an optical component is provided, including a constraint component, the constraint component including a barrier wall forming a plurality of preset light-emitting channels for light beams to pass through, the preset light-emitting channels having a first main light-emitting direction, the first main light-emitting direction forming an angle θ with the vehicle's forward direction, the angle θ satisfying: 0 ≤ θ < 60°; and a reflection component, at least a portion of the barrier wall of the preset light-emitting channels being provided with the reflection component, the reflection component having a second main light-emitting direction, the second main light-emitting direction forming an angle α with the vehicle's forward direction, the angle α satisfying: 0 ≤ α < 45°, and α < θ.

[0006] Optionally, the first main light emission direction is one of the following directions: The direction perpendicular to the light-incident side of the preset light-out channel; The direction perpendicular to the light-emitting side of the preset light-emitting channel; The optical axis direction of the light beam that enters the preset light exit channel via the light incident side.

[0007] Optionally, the second main light emission direction is the optical axis direction of the reflective component.

[0008] Optionally, the reflecting surface of the reflecting component is a parabolic surface.

[0009] Optionally, the reflection component and the constraint component are formed as a single unit.

[0010] Optionally, it further includes: a light guide assembly, the light guide assembly including multiple light guide units, the light guide units being located on the light-emitting side of the preset light-emitting channel.

[0011] Optionally, the light guide unit has a diffusion coating on the side facing the constraint component.

[0012] Optionally, the diffusion coating includes a white paste, a filler, a diluent, a curing agent, and a blue pigment.

[0013] Optionally, the light guide assembly has a shielding coating on the side facing the constraint assembly, and the shielding coating is located between adjacent light guide units.

[0014] In another aspect of this application, a vehicle lamp is provided, including: a light source and the aforementioned optical components, wherein the light source is disposed on the light-incident side of the preset light-out channel.

[0015] In another aspect of this application, a vehicle is provided, including the vehicle lights described above.

[0016] The optical components, vehicle lamps, and vehicles provided in this application embodiment emit light through a preset light-emitting channel formed by the baffle of the constraint component. When the light beam propagates within the preset light-emitting channel, part of the light beam can be directly emitted from the light-emitting side of the preset light-emitting channel along the first main light-emitting direction, while the other part of the light beam will encounter a reflection component provided by at least part of the baffle of the preset light-emitting channel, and the reflection component will emit part of the light beam out of the preset light-emitting channel along the second main light-emitting direction. The first main light-emitting direction forms an angle θ with the vehicle's forward direction, where 0 ≤ θ < 60°; the second main light-emitting direction forms an angle α with the vehicle's forward direction, where 0 ≤ α < 45°. Thus, the range of angles formed between the first and second main light-emitting directions and the vehicle's forward direction can increase the viewing angle of the light beam emitted from the preset light-emitting channel. This is especially suitable when optical components are installed on a vehicle, and one arrangement of the preset light-emitting channels is at an angle to the vehicle's forward direction, such as the left and right headlights of a vehicle, extending from the front to the side of the vehicle. In scenarios where the light emitted from only the preset light-emitting channels cannot meet the viewing angle range of the headlights and the optical efficiency is low. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Please refer to Figure 1 , Figure 3 As shown, this application embodiment provides an optical component, including a constraint component 10 and a reflection component 40.

[0024] The constraint component 10 includes a barrier wall 101, which forms a plurality of preset light-emitting channels 102 for the light beam to pass through. The preset light-emitting channels 102 have a first main light-emitting direction F2, and the first main light-emitting direction F2 forms an angle θ with the vehicle forward direction F1. The angle θ satisfies: 0≤θ<60°.

[0025] At least part of the pre-set light emission channel 102 has a barrier wall 101 with a reflective component 40. The reflective component 40 has a second main light emission direction F3. The second main light emission direction F3 forms an angle α with the vehicle forward direction F1. The angle α satisfies: 0≤α<45° and α<θ.

[0026] The baffle 101 forms the boundary of the preset light-emitting channel 102 to constrain the light-emitting range, confining the light beam to propagate within the preset light-emitting channel 102 and exiting from the light-emitting side of the preset light-emitting channel 102. The baffle 101 forms multiple preset light-emitting channels 102 for the light beam to pass through. The multiple preset light-emitting channels 102 are arranged side by side along the arrangement direction F5, or the multiple preset light-emitting channels 102 are arranged in an array. The baffle 101 separates adjacent preset light-emitting channels 102, allowing the light beam to propagate and exit within its respective preset light-emitting channel 102.

[0027] In addition to the constraint component 10, this application also includes a reflection component 40. If the reflection component 40 is not provided, during the propagation of the light beam towards the light-emitting side of the preset light-emitting channel 102, part of the light beam will hit the sidewall of the preset light-emitting channel 102. Due to the angle setting of the preset light-emitting channel 102, the reflected light from this part of the beam is blocked and cannot exit from the light-emitting side of the preset light-emitting channel 102, resulting in low overall optical efficiency of the optical components and hindering the improvement of the brightness of the lamp pixels.

[0028] Therefore, this application provides a reflective component 40 in at least part of the barrier 101 of the preset light emission channel 102, which can reflect the light beam blocked by the barrier 101 out of the preset light emission channel 102, so that these light beams can also be emitted from the light emission side of the preset light emission channel 102.

[0029] Therefore, in the optical component provided in this application embodiment, the light beam is emitted through the preset light emission channel 102 formed by the baffle 101 of the constraint component 10. When the light beam propagates in the preset light emission channel 102, part of the light beam can be directly emitted from the light emission side of the preset light emission channel 102 along the first main light emission direction F2, and the other part of the light beam will encounter the reflection component 40 provided in at least part of the baffle 101 of the preset light emission channel 102. The reflection component 40 will emit part of the light beam out of the preset light emission channel 102 along the second main light emission direction F3. The first main light-emitting direction F2 forms an angle θ with the vehicle's forward direction F1, where θ satisfies: 0 ≤ θ < 60°; the second main light-emitting direction F3 forms an angle α with the vehicle's forward direction F1, where α satisfies: 0 ≤ α < 45°. Thus, the range of angles formed between the first main light-emitting direction F2 and the second main light-emitting direction F3 and the vehicle's forward direction can increase the viewing angle of the light beam emitted from the preset light-emitting channel 102. This is especially suitable when optical components are installed on a vehicle, and the arrangement direction F5 of the preset light-emitting channel 102 is at an angle to the vehicle's forward direction, such as the left and right headlights of the vehicle, which extend from the front to the side of the vehicle. In scenarios where the light emitted from the preset light-emitting channel 102 alone cannot meet the viewing angle range of the headlights and the optical efficiency is low.

[0030] With the above settings, the light beams that can be directly emitted from the light-emitting side of the preset light-emitting channel 102 and the light beams that are directed toward the reflective component 40 can converge toward the light-emitting side of the preset light-emitting channel 102 as much as possible. The light beams can be emitted more from the light-emitting side of the preset light-emitting channel 102, thereby improving the optical efficiency and utilization of the emitted light beams and thus improving the brightness of the pixel dot lamps.

[0031] like Figure 2 As shown, on the cross section of the plane where the vehicle's vertical axis direction F4 and the vehicle's forward direction F1 are located; beams 01 and 02 are both emitted from the light source 21 and emitted directly through the light-emitting side of the preset light-emitting channel 102, while beam 03 is emitted from the light source 21, shines on the reflector 40, and is emitted by the reflector 40 toward the light-emitting side of the preset light-emitting channel 102.

[0032] Furthermore, the first main light emission direction F2 is one of the following directions: the first main light emission direction F2 is perpendicular to the light input side of the preset light emission channel 102; the first main light emission direction F2 is perpendicular to the light emission side of the preset light emission channel 102; and the optical axis direction of the light beam that enters the preset light emission channel 102 via the light input side.

[0033] In an embodiment where the first main light emission direction F2 is perpendicular to the light input side of the preset light emission channel 102, a light source 21 is generally provided on the light input side of the preset light emission channel 102. The light source 21 emits a light beam toward the light output side of the preset light emission channel 102. Since the first main light emission direction F2 is perpendicular to the light input side of the preset light emission channel 102, the light beam emitted by the light source 21 can be emitted more directly toward the light output side of the preset light emission channel 102.

[0034] In an embodiment where the first main light emission direction F2 is perpendicular to the light emission side of the preset light emission channel 102, the light source 21 faces the light emission side of the preset light emission channel 102, and the first main light emission direction F2 is perpendicular to the light emission side of the preset light emission channel 102. This can also make the light beam emitted by the light source 21 more directly emitted towards the light emission side of the preset light emission channel 102.

[0035] In the embodiment where the first main light-emitting direction F2 enters the optical axis direction of the light beam entering the preset light-emitting channel 102 via the light-incident side, the light beam entering the preset light-emitting channel 102 generally propagates along the optical axis direction. When the first main light-emitting direction F2 enters the optical axis direction of the light beam entering the preset light-emitting channel 102 via the light-incident side, the light beam entering the preset light-emitting channel 102 can be emitted more along the optical axis direction through the light-emitting side of the preset light-emitting channel 102.

[0036] In addition, in some embodiments, the second main light output direction F3 can be set as the optical axis direction of the reflector 40. The light beam reflected by the reflector 40 propagates along the optical axis direction of the reflector 40. Therefore, the light beam directed towards the reflector 40 can also be emitted out of the preset light output channel 102 along the optical axis direction of the reflector 40 more often.

[0037] In some embodiments, the reflecting surface of the reflecting component 40 is a parabolic surface 41. The light beam incident on the reflecting component 40 is reflected by the parabolic surface 41 and then converges and exits towards the light-emitting side of the preset light-emitting channel 102. The parabolic surface 41 collimates and converges the light beam after reflection. This collimating and converging characteristic of the parabolic surface 41 allows for better light beam collection, enabling the light beam to exit the preset light-emitting channel 102 through the parabolic surface 41, further improving the utilization rate of the light beam. Furthermore, the reflecting surface of the reflecting component 40 can also be a parabolic-like surface capable of achieving the function of the parabolic surface 41; this application is not limited to this.

[0038] In some embodiments, the reflective component 40 may be integrated with the constraint component 10. When the reflective component 40 and the constraint component 10 are integrated, the assembly tolerance and interference between the reflective component 40 and the constraint component 10 can be reduced, effectively reducing the resulting optical deviation. It can also reduce component connection losses and failure risks in traditional split designs. The integrated design can save space in the optical component and improve the overall reliability and compactness of the optical component.

[0039] On the other hand, such as Figure 2 As shown, the optical component may also include a light guide component. The light guide component may include multiple light guide units 30, which are located on the light-emitting side of the preset light-emitting channel 102. The light guide unit 30 is used to guide the light beam in the preset light output channel 102 out from the light output side of the light guide unit 30. The light guide unit 30 can be set one-to-one with the preset light output channel 102.

[0040] Specifically, the light-emitting side of the light-guiding unit 30 forms a light-emitting surface 31. After passing through the constraint component 10 and the reflection component 40, the light beam is emitted from the light-emitting surface 31 to display a light beam with a preset light pattern.

[0041] Based on this, such as Figure 3 , Figure 4 As shown, a diffusion coating 33 is provided on the side of the light guide unit 30 facing the constraint component 10. The diffusion coating 33 is specifically located on the side of the light guide unit 30 facing the constraint component 10. The diffusion coating 33 can be used to improve the uniformity of the light beam emitted through the light guide unit 30.

[0042] For example, the diffusion coating 33 includes a white paste, a filler, a diluent, a curing agent, and a blue pigment to improve color.

[0043] In addition, a shielding coating 32 may be provided on the side of the light guide assembly facing the constraint assembly 10, and the shielding coating 32 is located between adjacent light guide units 30.

[0044] When the masking coating 32 is located between adjacent light guide units 30, it can prevent light beams from being emitted from adjacent light guide units 30, making the emitted light beams from each light guide unit 30 clearer and the pixelation display of the optical components more contrasting.

[0045] In summary, the optical component provided in this application embodiment, through the cooperative arrangement of the constraint component 10 and the reflection component 40, allows the reflection component 40 to reflect the light beam incident on the side wall of the baffle 101 in a predetermined direction. This ensures that the light beam, after passing through the reflection component 40, exits through the preset light-emitting channel 102, improving the utilization rate of the collected light beam. Furthermore, a portion of the light beam can be directly emitted through the preset light-emitting channel 102, improving the overall light-emitting efficiency of the optical component and the brightness of the illumination pixels. Figure 5 An actual rendering of the optical components of this application is shown.

[0046] Based on this, the present application also discloses a vehicle lamp, including a light source 21 and any of the above optical components, wherein the light source 21 is disposed on the light-incident side of the preset light-emitting channel 102.

[0047] For example, a PCB board 20 is provided on the light-incident side of the preset light-emitting channel 102, and a light source 21 is provided on the PCB board 20. The PCB board 20 drives the light source 21 to emit light beams. Part of the light beams are emitted directly through the preset light-emitting channel 102, and part of the light beams that are directed toward the barrier wall 101 are reflected and emitted by the reflector 40.

[0048] The constraint component 10 and the reflective component 40 work together to improve the light output efficiency of the vehicle lights and the brightness of the lighting pixels compared to existing technologies, thereby enhancing the customer experience.

[0049] Of course, the optical components of this application can be used not only in vehicle lamps, but also in other lighting systems, and this application does not make any specific limitations on them.

[0050] On the other hand, embodiments of this application also provide a vehicle including vehicle lights as described above.

[0051] Because vehicle lights have the function of improving the utilization rate of the beam and increasing the brightness of the lighting pixels, vehicles equipped with them emit brighter light, which is beneficial to safe driving.

[0052] The vehicle lighting fixture and the vehicle itself possess the same structure and beneficial effects as the optical components in the foregoing embodiments. The structure and beneficial effects of the optical components have been described in detail in the foregoing embodiments and will not be repeated here.

[0053] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any 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.
