As a light signal device that conveys the autonomous driving status of a vehicle, the ADS (Autonomous Driving System or Advanced Driving System) light, or ADS sign / marker light, is also called an autonomous driving system sign / marker light or driving automation system sign / marker light, hereinafter referred to as "ADS light," and its technology has developed accordingly. Based on the placement of ADS lights within the vehicle lights, they are generally divided into two types: one is set separately and isolated from other functional signal lights, and the other is mixed or partially mixed with other functional signal lights.

[0003] The existing technical solutions are illustrated by the following patent.

Detailed Implementation

[0138] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed account of an optical system, an optical system control method, a vehicle lighting fixture, and a vehicle as proposed in this application. The advantages and features of this application will become more apparent from the following description and claims.

[0139] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the description below.

[0140] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0141] like Figure 1 As shown in Figure 2, this application provides an optical system including at least one first light source component 101, at least one second light source component 102, and an optical component 90. Light emitted from the first light source component 101 passes through the optical component 90 and is emitted from the first light-emitting region 901 of the light-emitting surface 9 of the optical component. Light emitted from the second light source component 102 passes through the optical component and is emitted from the second light-emitting region 902 of the light-emitting surface 9 of the optical component. There is at least a partial overlap between the first light-emitting region 901 and the second light-emitting region 902.

[0142] In this embodiment, the light emitted from the first light-emitting area 901 is used as the first light function, and the light emitted from the second light-emitting area 902 is used as the second light function. In this embodiment, the first light function is used as a marker light for the driving automation system, and the second light function is used as other light functions with a different color from the first light function, such as vehicle signal lights such as front position lights, front daytime running lights, rear position lights, rear reversing lights, brake lights, turn signals, or side marker lights, or vehicle lighting such as high beams, low beams, cornering lights, or front fog lights, or it can be ambient lighting. This application embodiment does not make specific limitations on this.

[0143] Among them, such as Figure 2A As shown, the light-emitting surface 9 of the optical component is illuminated at different times to perform the first light-emitting function of the first light-emitting region 901 and the second light-emitting region 902, respectively, with the first light-emitting region 901 and the second light-emitting region 902 completely overlapping. In some variations, such as... Figure 2BThe first light-emitting region 901 and the second light-emitting region 902 shown can partially overlap to form an overlapping region 900. The overlapping region 900 is lit up at different times to perform the first light function of part of the first light-emitting region 901 and the second light function of part of the second light-emitting region 902.

[0144] In this embodiment, the optical system enables the reuse of the structure and function of the vehicle's driver automation system (ADS) sign light and other signal lights. The first light-emitting area 901 of the optical component 90 in the optical system emits light from the ADS sign light, and the second light-emitting area 902 of the optical component 90 emits light from other vehicle signal lights. Therefore, based on the original vehicle signal light structure, by ensuring at least partial overlap between the first light-emitting area 901 and the second light-emitting area 902, and reusing the same light-emitting surface of the optical component, the cost of separately designing and manufacturing the ADS sign light, as well as the overall space occupied by the vehicle lights, are effectively reduced. Furthermore, it also enables the integration of vehicle lighting optical systems that combine ADS light functions and graphic display functions, and / or integrate ADS lights. Simultaneously, a control method for incorporating ADS lights is also provided.

[0145] The specific structure and functions of the optical system provided in this embodiment will be described in further detail below:

[0146] In one or more embodiments, the first light source assembly 101 may include a first light source capable of emitting light of a first light color. In some variations, the first light source assembly 101 may include a second light source and a first color filter optical element. Light emitted from the second light source, after passing through the first color filter optical element, is capable of emitting light of the first light color.

[0147] In one or more embodiments, the second light source assembly 102 may include a third light source capable of emitting light of a second light color. In some variations, the second light source assembly 102 may include a fourth light source and a second color filter optical element, wherein light emitted from the fourth light source, after passing through the second color filter optical element, is capable of emitting light of a second light color.

[0148] In this embodiment, the light emitted from the light-emitting surfaces 104 of the first light source assembly 101 and the second light source assembly 102 can be directly provided by the light source body 1, or provided by a combination of the light source body 1 and the color filter optical element 2. The first, second, third, and fourth light sources can be a single LED, multiple LEDs, or a component packaged with multiple LED chips. They can also be laser light sources, filament bulbs, gas discharge lamps, etc. This embodiment does not impose specific limitations on these aspects.

[0149] In one embodiment, such as Figure 3The schematic diagrams of the light source components with different light functions are not intended to limit the positional relationship or arrangement of the light source components. Each light source component can be used individually or in combination. Figure 3 In the diagram, from left to right, the components are: a second light source assembly 102 for generating white light from front position lights, front daytime running lights, and rear reversing lights; a first light source assembly 101 for generating blue-green light from a driver automation system marker light; a second light source assembly 102 for generating red light from rear position lights and brake lights; and a second light source assembly 102 for generating amber light from turn signals. Other single or multiple colors that perform light functions are also within the scope of this application, but this application is not intended to limit the scope of protection.

[0150] The first light source assembly 101, used to generate the light for the driving automation system indicator lights, can directly use a blue-green light source and emit blue-green light through the light source emitting surface 104, or it can use a combination of a white light source and a blue-green color filter optical element 2 to generate the blue-green light for the driving automation system indicator lights. The second light source assembly 102, used to generate the front position lights, front daytime running lights, and rear reversing lights, can use a white light source to generate white light for the front position lights, front daytime running lights, and rear reversing lights. The second light source assembly 102, used to generate the rear position lights and brake lights, can use a red light source and emit red light through the light source emitting surface 104, or it can use a combination of a white light source and a red color filter optical element 2 to generate red light for the rear position lights and brake lights. The second light source assembly 102, used to generate the turn signals, can use an amber light source and emit amber light through the light source emitting surface 104, or it can use a combination of a white light source and an amber color filter optical element 2 to generate amber light for the turn signals. Other methods of generating light sources of the desired color are also within the scope of this application. Embodiments that directly use the light source body 1 can reduce the number of parts and lower costs. In embodiments using the light source body 1 and color filter optical elements 2, different light colors can be achieved using only one color of light source in conjunction with different color filter optical elements 2, offering greater flexibility.

[0151] In one embodiment, such as Figures 41-43 As shown, the first light source assembly 101 and the second light source assembly 102 can be combined to form a bi-light LED 105.

In the above overall arrangement, the first light source assembly 101 and the second light source assembly 102 can be arranged alternately or partially alternately. The arrangement trend of the first light source assembly 101 and the second light source assembly 102 can be similar to the shape trend of the optical system. The first light source assembly 101 and the second light source assembly 102 can be mounted on the same circuit board or on different circuit boards. Multiple pairs of first light source assemblies 101 and second light source assemblies 102 can be incident on the same optical component or on different optical components; this application can achieve more variations, which will not be elaborated here.

At least one first light source component 101 is disposed at the first light-incident end of the light guide 3, and at least one second light source component 102 is disposed at the second light-incident end of the light guide 3.

The light guide 3 includes a first light-incident end 111 and a second light-incident end 112. The first light-incident end 111 and the second light-incident end 112 are set separately and converge into the same light guide 3. The light output by the first light source component 101 and the second light source component 102 passes through the corresponding first light-incident end 111 and the second light-incident end 112 respectively, and after passing through the body of the light guide 3, it is emitted from its light-emitting surface.

[0180] like Figure 23 , Figure 24 As shown, in one embodiment, there are several combined structures consisting of a first light source component 101, a second light source component 102, and corresponding optical components. In any combined structure, the optical components are configured as light guide channels 1001 / light guide units 1002. A first light-shielding element 601 is located between adjacent light guide channels 1001 / light guide units 1002, forming a light barrier between adjacent light guide channels 1001 / light guide units 1002 during light transmission. A second light-shielding element 602 is located between the light-emitting ends of adjacent light guide channels 1001 / light guide units 1002, forming a light barrier between adjacent light guide channels 1001 / light guide units 1002 during light emission.

[0181] The optical components may also optionally include a light-transmitting element 603, which is disposed on the light-emitting side of a combination structure consisting of a first light source component 101, a second light source component 102 and a corresponding optical component. The second light-shielding element 602 is disposed in the light-transmitting element 603 and is located between the light-emitting ends of adjacent optical components.

[0182] In one or more embodiments, the optical component is provided with a plurality of first light-incident ends 111 and second light-incident ends 112, the first light-incident ends 111 and the second light-incident ends 112 being located on the same side of the optical component, and at least a portion of the first light-incident ends 111 and at least a portion of the second light-incident ends 112 being alternately arranged.

[0183] In this optical component, the first light-incident end 111 and the second light-incident end 112 are alternately arranged on the same side. A plurality of first light-incident light-generating components 101 are respectively disposed at different first light-incident ends 111 of the optical component, and a plurality of second light-incident light-generating components 102 are respectively disposed at different second light-incident ends 112 of the optical component. A continuous and uniformly distributed first light-emitting region 901 and second light-emitting region 902 are formed in the light-emitting surface of the optical component. Figure 34 Multiple first light-incident ends 111 and second light-incident ends 112 are shown. The first light-incident ends 111 and second light-incident ends 112 can be alternately arranged, so that the first light source assembly 101 and the second light source assembly 102 are also alternately arranged. However, this application is not limited to this, and only some of the first light-incident ends 111 and second light-incident ends 112 can be alternately arranged.

[0184] In one or more embodiments, the optical component has a plurality of first light-incident ends and second light-incident ends, the first light-incident ends and the second light-incident ends are located on different sides of the optical component, and at least a portion of the first light-incident ends and at least a portion of the second light-incident ends are aligned or staggered.

[0185] In this optical component, the first and second light-incident ends arranged on different sides are aligned or staggered. A plurality of first light-source components 101 are respectively disposed at different first light-incident ends of the optical component, and a plurality of second light-source components 102 are respectively disposed at different second light-incident ends of the optical component. In the light-emitting surface of the optical component, when the first and second light-incident ends are aligned, the first light-emitting region 901 and the second light-emitting region 902 completely overlap; when the first and second light-incident ends are staggered, the first light-emitting region 901 and the second light-emitting region 902 are partially misaligned, adapting to the usage requirements of vehicle driving automation system sign lights and other signal lights in different application scenarios. For example... Figure 16 , 17 Several first light-incident ends and second light-incident ends are located on different sides of the optical component.

[0186] In one or more embodiments, the optical component includes a plurality of light-incident ends, which are arranged along the shape trend of the light-emitting surface of the optical component to meet the shape requirements.

[0187] Among them, several first light source components 101 and second light source components 102 correspond to multiple light-incident ends and are arranged along the shape trend of the light-emitting surface of the optical component, so that the distribution positions of the first light source components 101 and second light source components 102 are precisely matched with the light distribution of the light-emitting area of ​​the light-emitting surface of the optical component, such as...

The first light source assembly 101 is disposed at the light-incident end of the first light guide element 311, and the second light source assembly 102 is disposed at the light-incident end of the second light guide element 312. The light emitted from the source component 101 and the second light source component 102 passes through the corresponding focusing element 11, the first light guide element 311 and the second light guide element 312 respectively, and is emitted from the smooth and continuous light-emitting surface after the first light guide element 311 and the second light guide element 312 are combined. In the light-emitting surface 9 of the smooth and continuous optical component constructed after the first light guide element 311 and the second light guide element 312 are combined, the first light-emitting region 901 and the second light-emitting region 902 can completely overlap or partially overlap, so as to realize the reuse of the light-emitting surface of ADS and other optical functions.

[0190] The structural combination of the first light guide element 311, the second light guide element 312, the light focusing element 11, the first light source assembly 101 and the second light source assembly 102, in addition to realizing the aforementioned signal light function, can also be used to realize the functional combination of low beam headlights, high beam headlights, auxiliary low beam headlights, auxiliary high beam headlights and driving automation system sign lights.

[0191] In this embodiment, the first light guide element 311 can be specially designed with optical patterns or diffusion structures for the ADS lamp to ensure that the light-emitting area (first light-emitting area 901) meets the ADS indicator standards (such as specific flashing patterns, colors, and brightness) in terms of viewing angle, brightness, and uniformity. At the same time, the first light guide element 311 and the second light guide element 312 are combined to form a smooth and continuous light-emitting surface, achieving visual aesthetics.

[0192] Figure 49 As shown, in one embodiment, taking a reflective thick-walled optical component as an example, the first light source component 101 and the second light source component 102 are respectively disposed at the first light-incident end 111 and the second light-incident end 112 of the thick wall 4, and are emitted from the light-exiting surface of the thick wall 4 after being reflected by the reflective surfaces disposed at the first light-incident end 111 and the second light-incident end 112, respectively. In this embodiment, the first light source component 101 corresponds to the first light-incident end 111, and the second light source component 102 corresponds to the second light-incident end 112. The first light-incident end 111 and the second light-incident end 112 are staggered into two rows. The light-incident surface, reflective surface, etc. of the first light-incident end 111 and the second light-incident end 112 can be configured according to different lighting requirements provided by the ADS lamp and the second light function. At the same time, the staggered distance between the first light source component 101 and the second light source component 102 is beneficial for heat dissipation and improves the stability of the optical system.

[0193] like Figure 50 As shown, in one embodiment, taking a double-reflective thick-walled optical component as an example, the first light source component 101 and the second light source component 102 are respectively disposed at the light-incident ends of the first reflective thick wall 4041 and the second reflective thick wall 4042. Light emitted from the first light source component 101 enters the second reflective thick wall 4042 via the first reflective thick wall 4041 and exits from the light-emitting surface of the second reflective thick wall 4042. Light emitted from the second light source component 102 passes through the second reflective thick wall 4042 and exits from the light-emitting surface of the second reflective thick wall 4042. The light-incident surface, reflective surface, and light-emitting surface of the first reflective thick wall 4041 can be configured according to the lighting requirements of the ADS lamp. Simultaneously, the staggered distance between the first light source component 101 and the second light source component 102 facilitates heat dissipation and improves the stability of the optical system; furthermore, the first light source component 101 and the second light source component 102 can be arranged on different circuit boards, which is beneficial for flexible spatial layout. Furthermore, in this embodiment, the positions of the first light source component 101 and the second light source component 102 can also be interchanged, but this application is not limited thereto.

[0194] like Figure 51 As shown, in one embodiment, taking a double-reflective thick-walled optical component as an example, the first light source component 101 and the second light source component 102 are respectively disposed at the light-incident ends of the first reflective thick wall 4041 and the second reflective thick wall 4042. Light emitted from the first light source component 101 enters the second reflective thick wall 4042 via the first reflective thick wall 4041 and exits from the light-emitting surface of the second reflective thick wall 4042. Light emitted from the second light source component 102 passes through the second reflective thick wall 4042 and exits from the light-emitting surface of the second reflective thick wall 4042. Figure 50 The difference is that in this embodiment, the position of different light source components can be adjusted by the thick-walled extension of the light source component, and the first reflective thick wall 4041 and the second reflective thick wall 4042 are bent, which can reduce the space requirement in the direction of light emitted from the light-emitting surface.

[0195] like Figure 52As shown, in one embodiment, taking multiple light-transmitting elements as an example, the first light source assembly 101 is disposed corresponding to the first light-transmitting element 131. The first light-transmitting element 131 has a diffusion pattern on one side of its light-emitting surface, and a reflective surface is also disposed on the same side of its light-emitting surface. The second light source assembly 102 is disposed corresponding to the second light-transmitting element 132. The second light-transmitting element 132 has a reflective pattern 1321 on one side of its light-emitting surface. The first light source assembly 101 is positioned laterally toward the first light-transmitting element 131 facing the reflecting surface 12. Light emitted from the first light source assembly 101 passes through the first light-transmitting element 131 and illuminates the reflecting surface 12. After reflection by the reflecting surface 12, the light then passes through the first light-transmitting element 131 toward the second light-transmitting element 132. Part of the light is reflected back to the first light-transmitting element 131 by the reflective pattern 1321 of the second light-transmitting element 132, while another part passes through the portion of the second light-transmitting element 132 without the reflective pattern 1321 (or may also pass through a portion of the reflective pattern 1321) and exits through the light-emitting surface of the second light-transmitting element 132. Thus, the light emitted from the first light source assembly 101 can be diffused multiple times by the diffusion pattern, forming a large illuminated area. Light emitted from the second light source assembly 102 undergoes total internal reflection within the second light-transmitting element 132 and exits through the reflective pattern 1321 of the second light-transmitting element 132 toward the light-emitting surface of the second light-transmitting element 132. Thus, through the above configuration, the light-emitting surface 9 of the optical component will form a first light-emitting area corresponding to the first light source component 101 and a second light-emitting area corresponding to the second light source component 102. The first light-emitting area and the second light-emitting area do not completely overlap, realizing different lighting areas for different light functions. In the case of sharing the light-emitting surface 9 of the optical component, in addition to the light color, a way to distinguish different light functions is further provided.

[0196] like Figure 53 As shown, in one embodiment, taking a composite thick-walled optical component as an example, the first light-incident ends 111 and 112 of the first light-incident component 101 and the second light-incident component 102 are respectively arranged in different directions, providing flexible arrangement of the first light-incident component 101 and the second light-incident component 102. Furthermore, since the first light-incident component 101 and the second light-incident component 102 are arranged in different positions, the heat dissipation requirement can be reduced. Further, in order to ensure that light incident from different light-incident ends can be emitted only from the light-emitting surface 9 of the optical component, multiple reflective surfaces can be provided on the thick wall to adjust the direction of light propagation.

[0197] like Figure 54As shown, in one embodiment, taking a direct-firing thick-walled optical component as an example, the light-incident end of the thick-walled 4 is a focusing element 11, and the same focusing element 11 simultaneously corresponds to the first light source component 101 and the second light source component 102. To improve the lighting effect of the first light source component 101 and the second light source component 102, the focusing element 11 provides respective light-incident surfaces for the first light source component 101 and the second light source component 102 as a first light-incident end 111 and a second light-incident end 112. The first light-incident end 111 and the second light-incident end 112 can be configured according to different lighting requirements provided by the ADS lamp and the second light function.

[0198] like Figure 55 As shown, in one embodiment, taking a light guide 3 and a thick wall 4 as examples of optical components, a first light source component 101 is disposed at the light-incident end of the light guide 3, and the light-exiting surface of the light guide 3 is disposed corresponding to one light-incident end of the thick wall 4. A second light source component 102 is disposed at the other light-incident end of the thick wall 4. Thus, the light from the first light source component 101 is emitted through the light guide 3 to the thick wall 4 and exits from the light-exiting surface of the thick wall 4; the light from the second light source component 102 is incident on the thick wall 4 and exits from the light-exiting surface of the thick wall 4. This allows for different lighting methods for the ADS lamp and the second light function, while reducing the number of thick-walled components and utilizing the light guide to reduce the number of light sources and circuit board area, thereby lowering costs.

[0199] like Figure 56 As shown, in one embodiment, taking a reflective thick-walled optical component as an example, the thick wall 4 is provided with a first light-incident end 111 and a second light-incident end 112, with a gap between the first light-incident end 111 and the second light-incident end 112. A first light source component 101 and a second light source component 102 are respectively configured corresponding to the first light-incident end 111 and the second light-incident end 112. Light emitted from the first light source component 101 enters the thick wall 4 through the first light-incident end 111, undergoes reflection and passes through the gap between the first light-incident end 111 and the second light-incident end 112, and then enters the thick wall 4 again, exiting from the light-emitting surface of the thick wall 4. Light emitted from the second light source component 102 enters the thick wall 4 through the second light-incident end 112, is reflected by the reflective surface of the thick wall 4, and then exits from the light-emitting surface of the thick wall 4. Therefore, the different lighting requirements of the ADS lamp and the second light can be met through the gap between the first light-incident end 111 and the second light-incident end 112, and between the first light-incident end 111 and the second light-incident end 112. At the same time, only one thick wall is needed, reducing the cost of the optical system.

[0200] like Figure 57As shown, in one embodiment, taking the optical component using multiple light-transmitting elements as an example, the first light source component 101 and the second light source component 102 correspond to the first light-transmitting element 131 and the second light-transmitting element 132, respectively. Different reflective patterns can be respectively set on the side of the first light-transmitting element 131 and the side of the second light-transmitting element 132 facing away from the light-emitting surface. The light emitted from the first light source component 101 enters the first light-transmitting element 131 at an angle, undergoes total internal reflection inside the first light-transmitting element 131, and is reflected by the first pattern 1311 set on the side of the first light-transmitting element 131 facing away from the light-emitting surface, and is emitted towards the light-emitting surface of the first light-transmitting element 131, illuminating and forming the pattern 1311 of the first light-transmitting element 131. The light emitted from the second light source assembly 102 enters the second light-transmitting element 132 at an oblique angle, undergoes total internal reflection inside the second light-transmitting element 132, and is reflected by the second pattern 1312 disposed behind the light-emitting surface of the second light-transmitting element 132 before exiting towards the light-emitting surface of the second light-transmitting element 132. The light then passes through the first light-transmitting element 131 and exits from the light-emitting surface of the first light-transmitting element 131, illuminating the pattern 1312 of the second light-transmitting element 132. Preferably, the first pattern 1311 and the second pattern 1312 are staggered to avoid the first pattern 1311 affecting the illumination of the second pattern 1312. Preferably, the first light source assembly 101 and / or the second light source assembly 102 can also transmit light into the light-transmitting element through a light guide surrounding the side of the light-transmitting element. The light guide can be provided with reflective patterns for the first light source assembly 101 and / or the second light source assembly 102 to enter the second light-transmitting element 132 at an oblique angle. The positions of the first light source assembly 101 and the second light source assembly 102 can be interchanged, which will not be elaborated here. This application can achieve many more different variations, which will also not be elaborated here.

[0201] In one or more embodiments, such as Figure 25 As shown, the optical system may include a liquid crystal display panel 8, and the optical component is the backlight module 7 of the liquid crystal display panel 8.

[0202] The backlight module 7 includes at least one first light source component 101 and a second light source component 102. The first light source component 101 works with the liquid crystal display panel 8 to form a first color gamut based on a first light function, and the second light source component 102 works with the liquid crystal display panel 8 to form a second color gamut based on a second light function. The first color gamut is at least partially located outside the second color gamut.

[0203] The optical system switches between at least a first optical function and a second optical function for display.

[0204] In this embodiment, the optical system can realize the graphic and textual information display control of the driving automation system sign light based on the liquid crystal display panel 8, and the graphic and textual display function of the driving automation system sign light and the non-graphic and textual display (partial or full area lighting) can be used separately or in combination.

[0205] The backlight module 7 provides a displayable light source for the liquid crystal display panel 8. The liquid crystal display panel 8 is typically located on the light-emitting side or light-emitting surface of the backlight module 7 to ensure it can smoothly receive the light emitted by the backlight module 7. The liquid crystal display panel 8 can achieve the desired high-resolution display or indication by pixel-level control of the light emitted by the backlight module 7. The backlight module 7 includes a first light source assembly 101 and a second light source assembly 102, wherein the first light source assembly 101 and the second light source assembly 102 need to work together with the liquid crystal display panel 8 to form different color gamuts in different display modes.

[0206] The optical system can provide a first light function and a second light function. The first light function is that the first light source component 101 in the backlight module 7 emits light, which, after passing through the liquid crystal display panel 8, enables the liquid crystal display device to display colors within a first color gamut. The second light function is that the second light source component 102 in the backlight module 7 emits light, which, after passing through the liquid crystal display panel 8, enables the liquid crystal display device to display colors within a second color gamut.

[0207] Based on this, since the first color gamut is at least partially located outside the second color gamut, the optical system can display more colors by increasing the color gamut. Furthermore, in this embodiment, there is at least partial overlap between the first light-emitting region 901 and the second light-emitting region 902. This further reduces the cost of separately designing and manufacturing the sign lights for the driving automation system, as well as the overall space occupied by the vehicle lights, while still achieving the display function of different color gamuts.

[0208] In one or more embodiments, such as Figure 26 As shown, at least a portion of the display area of ​​the optical system serves as a illuminated area that matches the first light function.

[0209] The liquid crystal display panel 8 includes:

[0210] The array substrate 801 is located on the light-emitting side of the backlight module 7.

[0211] Liquid crystal molecule layer 802 is located on the side of array substrate 801 away from backlight module 7.

[0212] When the optical system is in its first light function, the array substrate 801 is configured to control the liquid crystal molecule layer 802 located in the illuminated area to be in a state of maximum light transmission.

[0213] The liquid crystal display panel 8 includes a lower polarizer 804, an array substrate 801, a liquid crystal molecule layer 802, a color filter 805, and an upper polarizer 803 arranged sequentially. The lower polarizer 804 is located on the light-emitting side of the backlight module 7 and is close to it, while the upper polarizer 803 is also located on the light-emitting side of the backlight module 7 but is far away from it.

[0214] In this embodiment, the array substrate 801 can be configured to perform pixel-level control on the deflection degree of the liquid crystal molecule layer 802. When the optical system is in the first light function, the array substrate 801 is configured to control the liquid crystal molecule layer 802 located in the illuminated area to be in the maximum light transmittance state. In other words, in this mode, the liquid crystal molecules corresponding to the pixels in the illuminated area are all in the maximum light transmittance state, thereby realizing the high brightness display of the driving automation system sign light and enabling the optical system to generate light that meets the color requirements of the driving automation system sign light.

[0215] In one or more embodiments, such as Figure 26 As shown, the liquid crystal display panel 8 includes:

[0216] The color filter 805 has a second light function for color display mode and a first light function for monochrome display mode.

[0217] When the first light function and the second light function match the same illuminated area, the first light function and the second light function use the color filter 805.

[0218] Alternatively, when the first light function and the second light function are matched with different illumination areas, the illumination areas matched by the first light function and the second light function are provided with different color filters 805; or, the illumination area matched by the second light function is provided with a color filter 805, while the illumination area matched by the first light function is not provided with a color filter 805.

[0219] In this embodiment, the second light source assembly 102 can work with the color filter 805 to achieve color display on the liquid crystal display panel 8, that is, the second light function is a color display mode to meet the usage requirements of other vehicle signal lights. The first light function is a monochrome display mode, that is, the light emitted by the first light source can be displayed in monochrome after passing through the liquid crystal display panel 8, thereby meeting the usage requirements of the driving automation system's sign lights.

[0220] When the first light function and the second light function match the same illumination area, the first light function and the second light function can reuse (i.e., share) the color filter 805. When the first light function and the second light function match different illumination areas, firstly, different color filters 805 are set for the illumination areas matched by the first light function and the second light function, such as a first color filter and a second color filter, where the first color filter is set in the illumination area matched by the first light function and the second color filter is set in the illumination area matched by the second light function. The first color filter can be a corresponding transparent filter, and the second color filter can be a filter containing RGB color filter units.

[0221] Alternatively, in a second aspect, the liquid crystal display panel 8 includes a color filter 805 located within the display area, and the color filter 805 is disposed in the illumination area matched by the second light function, while the color filter 805 is not disposed in the illumination area matched by the first light function. The second color filter may be a filter containing RGB color filter units.

[0222] In one or more embodiments, different filters include:

[0223] A color filter 805 is set in the illumination area matched by the second light function, and a transparent filter is set in the illumination area matched by the first light function.

[0224] The transparent filter is a colorless filter or a monochromatic filter that matches the color emitted by the first light source component 101.

[0225] In one or more embodiments, the optical system further includes at least one third light source component 103, the light emitted from the third light source component 103 passing through the optical component 90 and exiting from the third region of the light-emitting surface 9 of the optical component.

[0226] The first light-emitting region 901 overlaps with at least a portion of the second light-emitting region 902 and the third light-emitting region. The light emitted from the third light-emitting region is used as a third light function, which is used as another light function with a different color than the first light function and the second light function.

[0227] like Figure 27 As shown, in one embodiment, taking the optical component as a light guide 3 as an example, the first light source component 101, the second light source component 102 and the third light source component 103 are disposed at the light-incident end of the light guide 3. After the light from the first light source component 101, the second light source component 102 and the third light source component 103 passes through the light guide 3, it is emitted from the light-emitting surface of the light guide 3. In the light-emitting surface of the light guide 3, the first light-emitting region 901 overlaps with the second light-emitting region 902 and the third light-emitting region by at least a portion of the area.

[0228] like Figure 47 As shown, in one embodiment, the first light source component 101 and the second light source component 102 form a combined structure, and at the same time, the first light source component 101 and the third light source component 103 form a combined structure.

[0229] Based on the same concept, this application also provides a control method for an optical system, used to control the optical system as described in any one of the above descriptions. The control method includes: controlling the on / off state of the first light source component 101 and the second light source component 102 to achieve switching between the first light function and the second light function.

[0230] The optical system includes at least one first light source component 101 and a second light source component 102. The light emitted from the first light source component 101 passes through the optical component 90 and is emitted from the first light-emitting area 901 of the light-emitting surface 9 of the optical component, serving as the first light function. The light emitted from the second light source component 102 passes through the optical component 90 and is emitted from the second light-emitting area 902 of the light-emitting surface 9 of the optical component, serving as the second light function. By controlling the on / off state of the first light source component 101 and the second light source component 102, the light emitted from the first light-emitting area 901 and the light emitted from the second light-emitting area 902 of the light-emitting surface 9 of the optical component can switch between on / off states, thereby realizing the on / off switching control of the automatic system's sign light and other light functions.

[0231] In one or more embodiments, the optical system control method includes: when the driver automation system indicator lights and the vehicle hazard warning lights are simultaneously activated, the driver automation system indicator lights and the vehicle hazard warning lights can be displayed in a continuously illuminated manner, thereby ensuring the clarity and unambiguity of the critical signal (hazard warning lights) in emergency situations. In some variations, when the driver automation system indicator lights and the vehicle hazard warning lights are simultaneously activated, and the driver automation system indicator lights and turn signals are not mixed, a same-frequency and same-phase flashing display method is used. This same-frequency and same-phase flashing pattern clearly informs surrounding vehicles and pedestrians of the "no turning intention," avoiding misunderstandings caused by confusion between the hazard warning lights and single-sided turn signal patterns. In some variations, when the driver automation system indicator lights and turn signals are mixed, a same-frequency and different-phase flashing display method is used.

[0232] The combination of warning lights and turn signals in a driver automation system refers to the simultaneous illumination of two main functions (warning lights and turn signals) within the same optical system. These functions have separate light sources along the reference axis or are single light sources operating under different conditions, sharing a common viewing surface, which is the aforementioned optical system. Therefore, in this combined configuration, both hazard warnings and driver automation system indicators can be simultaneously displayed using a synchronous, out-of-phase flashing method.

[0233] In one or more embodiments, the optical system control method includes: mixing a driving automation system sign light with a turn signal, wherein during the entire cycle of the turn signal being activated, the area in which the driving automation system sign light and turn signal are mixed is: when the turn signal is illuminated, the driving automation system sign light is extinguished; when the driving automation system sign light is illuminated, the turn signal is extinguished.

[0234] When the driving automation system uses both the indicator lights and turn signals, the indicator lights and turn signals flash alternately. This allows for visual confirmation that throughout the entire process, there is no situation where two different colored light source components are simultaneously lit or neither is lit in any light-emitting area of ​​the optical component's light-emitting surface.

[0235] In one or more embodiments, the optical system control method includes: mixing a driving automation system marker light with a side marker light, wherein when the driving automation system marker light is turned on, the mixed side marker light is turned off, wherein, in response to the side marker light flashing with a turn signal, the area where the driving automation system marker light and the side marker light are mixed is: when the side marker light is illuminated, the driving automation system marker light is turned off; when the driving automation system marker light is illuminated, the side marker light is turned off.

[0236] When the driver automation system's indicator lights and side marker lights are used interchangeably, they flash alternately. This allows for visual confirmation that throughout the process, no area on the light-emitting surface of the optical components has both light sources of different colors simultaneously illuminated or neither illuminated. Therefore, prioritizing the clarity and safety of dynamic turn signals, the driver automation system indicator lights in that area are forcibly turned off the moment the side marker lights illuminate, ensuring that the turn warning signals can be independently seen and detected by road users. This avoids the weakening, confusion, or misunderstanding of turn intentions due to the superposition of two light signals. Simultaneously, the alternating flashing method allows for the display of two types of information on the same physical light group, depending on different scenarios and timings. This ensures that both types of information are effectively conveyed, preventing one type of information from being permanently obscured due to hardware mixing.

[0237] In one or more embodiments, the optical system control method includes: the optical system providing a graphic interaction function, the graphic interaction function being turned on and off synchronously with the driving automation system sign lights.

[0238] The graphic interaction function can only be activated when the indicator lights of the driving automation system are on, and should be deactivated when the indicator lights of the driving automation system are off.

[0239] In one embodiment, when the graphic interaction function is enabled, the Chinese text element "Autonomous Driving" is displayed by default. Alternatively, the autonomous driving system may display other elements or combinations of elements based on display requirements.

[0240] By controlling the indicator lights and graphic interaction functions of the automated driving system, it can be ensured that the graphic interaction function is only available when the vehicle is confirmed to be in autonomous driving mode. The information conveyed to the outside world (such as "Autonomous driving in progress" or "Yield to other vehicles") is supported by the actual system status, avoiding the issuance of erroneous or contradictory signals. For example, it avoids the confusion of displaying autonomous driving prompts while a human is driving. Furthermore, binding the activation permission of the graphic interaction function to the autonomous driving system means that it is not an independent function that can be arbitrarily activated by the user. This prevents misoperation or abuse, such as improper use of graphic information to interfere with other road users while manually driving. In addition, once the autonomous driving system exits (indicator lights turn off), the graphic interaction function immediately shuts down, eliminating the risk of information lag due to state transition delays and ensuring that the outside world receives information synchronized with the vehicle's current driving mode. Pedestrians and other drivers can visually automatically associate the "autonomous driving indicator light" with the "graphic information," clearly identifying that a vehicle displaying this light and text is in autonomous driving mode. This reduces the public's understanding cost and promotes effective communication between people and vehicles.

[0241] Based on the same concept, embodiments of this application also provide a vehicle optical signal device, including the optical system described above.

[0242] The vehicle optical signal device includes at least one first light source component 101, at least one second light source component 102, and an optical component.

[0243] The light emitted from the first light source assembly 101 passes through the optical assembly 90 and exits from the first light-emitting region 901 of the light-emitting surface 9 of the optical assembly. The light emitted from the second light source assembly 102 passes through the optical assembly 90 and exits from the second light-emitting region 902 of the light-emitting surface 9 of the optical assembly. There is at least a partial overlap between the first light-emitting region 901 and the second light-emitting region 902.

[0244] The light emitted from the first light-emitting area 901 is used for the first light function, and the light emitted from the second light-emitting area 902 is used for the second light function. The first light function is used as a sign light for the driving automation system, and the second light function is used for other light functions with a different color than the first light function.

[0245] Based on the same concept, this application also provides a vehicle lighting fixture, including the vehicle light signal device described above.

[0246] Based on the same concept, this application also provides a vehicle including the aforementioned vehicle lights.

[0247] The embodiments of this application have been described in detail above with reference to the accompanying drawings, but this application is not limited to the above embodiments. Even if various changes are made to this application, if these changes fall within the scope of the claims of this application and their equivalents, they shall still fall within the protection scope of this application.
