Description

Technical Field

[0001] This application belongs to the field of automotive technology, and in particular relates to an optical system, control method, vehicle lighting, and vehicle. Background Technology

[0002] As vehicle lighting functions continue to integrate and expand, in addition to traditional illumination and signal indication functions, vehicle lights are increasingly required to perform multiple lighting functions, including daytime running lights, front position lights, turn signals, auxiliary low beams, autonomous driving signal lights, and exterior ambient lighting. Different lighting functions typically correspond to different light color requirements and different illumination methods.

[0003] In existing technologies, to meet the light color requirements of different vehicle lighting functions, it is usually necessary to set up light sources with different emission colors corresponding to the number of light functions, in order to generate different colors of light adapted to different light functions. However, this approach results in a large number and variety of light sources in the vehicle lighting, leading to complex circuit board layout, complex drive control circuits, increased assembly difficulty, and higher manufacturing costs. In addition, the coexistence of multiple light sources occupies more installation space, which is not conducive to the miniaturization and integration design of vehicle lighting.

Detailed Implementation

[0041] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed account of an optical system, control method, vehicle lighting fixture, and vehicle according to this application. The advantages and features of this application will become more apparent from the following description and claims.

[0042] 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.

[0043] 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.

[0044] like Figure 1 As shown, a first aspect of the present application provides an optical system including at least one first light source component 1 and at least one second light source component 2.

[0045] The first light source component 1 can emit light of a first color, and the second light source component 2 can emit light of a second color. The first light color and the second light color are different colors.

[0046] On one hand, the first light source component 1 and the second light source component 2 can be used independently. When the first light source component 1 is lit alone, it emits light of a first light color, which can independently meet the color requirements of the first light function in vehicle regulations or be combined with other light source components to jointly meet the color requirements of the first light function in vehicle regulations. Alternatively, when the second light source component 2 is lit alone, it emits light of a second light color, which can independently meet the color requirements of the second light function in vehicle regulations or be combined with other light source components to jointly meet the color requirements of the second light function in vehicle regulations. In some variations, the light emitted by the first light source component 1 and the second light source component 2 when lit alone can independently meet the color requirements of the corresponding light function in vehicle regulations or be combined with other light source components to jointly meet the color requirements of the corresponding light function in vehicle regulations.

[0047] On the other hand, when the first light source assembly 1 and the second light source assembly 2 are lit, at least the light of the first light color emitted by the first light source assembly 1 and the light of the second light color emitted by the second light source assembly 2 are mixed and emitted as light of the third light color, so that the light of the third light color meets the color requirements of the third light function of the vehicle regulations, wherein the third light color is different from the first light color and the second light color.

[0048] Vehicle regulations specify requirements for lighting functions, including luminous intensity, chromaticity coordinates, and uniformity. The lighting functions in vehicle regulations refer specifically to signal light functions. Chromaticity coordinates (which can also be expressed using the chromaticity parameter range described below) are used to define the color requirements for signal light functions. Ambient lighting functions, since they do not require regulatory certification, can be considered independent of the lighting functions discussed herein.

[0049] In this embodiment, the light of the first light color emitted by the first light source component 1 can be emitted through the first light-emitting surface 3 to independently meet the color requirements of the first light function in vehicle regulations, or in combination with other light source components to jointly meet the color requirements of the first light function in vehicle regulations. The light of the second light color emitted by the second light source component 2 can also be emitted through the same first light-emitting surface 3 to independently meet the color requirements of the second light function in vehicle regulations, or in combination with other light source components to jointly meet the color requirements of the second light function in vehicle regulations. Furthermore, when the first light source component 1 and the second light source component 2 are lit, the light of the first light color and the light of the second light color are mixed and emitted as light of the third light color through the first light-emitting surface 3 of the optical system. The light of the third light color meets the color requirements of the third light function in vehicle regulations. In some variations, the optical system may also include a light path switching structure to switch the emitted light from the first light source component 1 and / or the second light source component 2 to an independent light-emitting surface when they emit light individually, to meet the requirement in vehicle regulations that no two of the first, second, and third light functions can be mixed. The optical path switching structure may be, for example, a mirror and / or a light guide that can be driven to rotate / translate / slide, so as to realize optical path switching as needed when emitting different light functions. This embodiment does not limit this.

[0050] In order to ensure that both the first light source component 1 and the second light source component 2 can independently meet the color requirements of the light function in accordance with vehicle regulations, the first light color is amber or red, the second light color is blue-green or blue, and the third light color is white. In this embodiment, amber or red, blue-green or blue, and white are not unique specific color parameters, but color categories that correspond to a range of chromaticity.

[0051] Different colors of light are essentially different in that they have different spectral distributions or dominant wavelengths. When two different colors of light are mixed in a certain proportion and emitted into the observer's field of vision, the human eye will perceive the color as a whole, thus presenting a new color that is different from each individual input color. The specific chromaticity parameters of the generated new color depend on the relative mixing ratio of the two input color lights. The relative mixing ratio includes, but is not limited to, the relative luminous flux, relative brightness, relative radiant energy, and other optical parameters of the two lights.

[0052] In this embodiment, the light emitted by the first light source component 1 is amber or red, and the amber or red light is used as the first light function; the light emitted by the second light source component 2 is blue-green or blue, and the blue-green light is used as the second light function; and by modulating the light energy ratio between the first light source component 1 and the second light source component 2, the amber or red light and the blue-green or blue light are mixed to generate white light, and the white light is used as the third light function.

[0053] Therefore, in the optical system provided in this embodiment, the first light source component 1 and the second light source component 2 can be light source components specially configured in the optical system to realize the first light function and the second light function, respectively. For the third light function, there is no need to set up a light source device corresponding to the third light function of the optical system. It is only necessary to reuse the amber or red light emitted by the first light source component 1 and the blue-green or blue light emitted by the second light source component 2 to mix and generate white light that meets the color requirements of the third light function. This effectively reduces the design complexity, manufacturing cost and overall space occupation of the optical system.

[0054] The specific structure and functions of the optical system provided in this embodiment will be described in further detail below: In one or more embodiments, in order to ensure that both the first light source component 1 and the second light source component 2 can independently meet the color requirements of the light function in accordance with vehicle regulations, the first light function, the second light function, and the third light function can be selected from the following combinations of light functions: The first light function is the turn signal function, the second light function is the driver automation system indicator light function, and the third light function is the daytime running light function, the front position light function, the reversing light function, the auxiliary low beam, the emblem light function, or a combination of any two or three of the aforementioned functions (excluding the combination of the reversing light and the front position light functions). The first light function is the rear position light function, the reversing light function, or a combination of the two functions; the second light function is the driving automation system indicator light function; and the third light function is the reversing light function, the emblem light function, or a combination of the two functions mentioned above.

[0055] Specifically, in one embodiment, when the first light source component 1 is lit alone, the emitted light of the first color is used as a turn signal; when the second light source component 2 is lit alone, the emitted light of the second color is used as a marker light for the driving automation system; when the first light source component 1 and the second light source component 2 are lit, the light of the first color and the light of the second color are mixed to generate light of the third color, which is used as a daytime running light, a front position light, a reversing light, an auxiliary low beam, a logo light, or a combination of any two or three of the aforementioned functions (excluding the combination of reversing light and front position light functions).

[0056] In another embodiment, when the first light source component 1 is lit alone, the emitted light of the first light color is used as a rear position light, a reversing light, or a combination of the two functions; when the second light source component 2 is lit alone, the emitted light of the second light color is used as a marker light for the driving automation system; when the first light source component 1 and the second light source component 2 are lit, the light of the first light color and the light of the second light color are mixed to generate light of the third light color, which is used as a reversing light, an emblem light, or a combination of the two functions.

[0057] In one or more embodiments, the light of a first light color emitted by the first light source component 1 has a first chromaticity parameter range, which at least partially overlaps with the chromaticity parameter range of the first light function in vehicle regulations to meet the color requirements of the first light function of the optical system; and / or, the light of a second light color emitted by the second light source component 2 has a second chromaticity parameter range, which at least partially overlaps with the chromaticity parameter range of the second light function in vehicle regulations to meet the color requirements of the second light function of the optical system.

[0058] Specifically, the chromaticity parameters of the light emitted by the first light source component 1 and the second light source component 2 can be adjusted respectively. In this embodiment, the first light color emitted by the first light source component 1, which needs to be combined with other light source components to meet the chromaticity parameter range requirements of the first light function in vehicle regulations, is used to realize the first light function; the second light color emitted by the second light source component 2, which needs to be combined with other light source components to meet the chromaticity parameter range requirements of the second light function in vehicle regulations, is used to realize the second light function. At the same time, some of the first light colors emitted by the first light source component 1 that do not meet the chromaticity parameter range requirements of the first light function in vehicle regulations can also be used to realize other light functions different from the first, second, and third light functions, or to be mixed with other colors of light to realize other light functions; similarly, some of the second light colors emitted by the second light source component 2 that do not meet the chromaticity parameter range requirements of the second light function in vehicle regulations can also be used to realize other light functions different from the first, second, and third light functions, or to be mixed with other colors of light to realize other light functions. This embodiment does not impose any limitations on this.

[0059] In one or more embodiments, the light of a first color emitted when the first light source component 1 is lit alone is as follows: The light of the first light color is located within the chromaticity parameter range of the first light function of the vehicle regulations, and the light of the first light color is emitted through the first light-emitting surface 3, independently meeting the color requirements of the first light function of the vehicle regulations; and / or, the light of the first light color is located within the first chromaticity parameter range, but not within the chromaticity parameter range of the first light function of the vehicle regulations, and the light of the first light color and the light of the second light color are mixed and emitted as light of the third light color at the first light-emitting surface 3.

[0060] Specifically, on the one hand, when the first light source component 1 is lit alone, the light emitted, which has a first light color and falls within the chromaticity parameter range of the first light function of the vehicle regulations, can be used to realize the first light function of the optical system. On the other hand, the light of the first light color emitted by the first light source component 1 can include light within the chromaticity parameter range of the first light function of the vehicle regulations and light outside the chromaticity parameter range of the first light function of the vehicle regulations. The portion of the light emitted by the first light source component 1 that has a first light color but does not fall within the chromaticity parameter range of the first light function of the vehicle regulations can be mixed with light of a second light color to form light of a third light color. Therefore, considering that the chromaticity parameter range of the first light function of the vehicle regulations may be unfavorable for color mixing to generate a third light color that meets regulatory requirements, by using a first light source component 1 whose chromaticity parameter range intersects with the first chromaticity parameter range, it is possible to simultaneously satisfy the first and third light functions required by vehicle regulations through chromaticity adjustment. Furthermore, chromaticity adjustment can be achieved through the chromaticity adjustment function of the light source itself within the light source component. In some variations, the chromaticity parameter range of the light emitted by the light source component can also be finely adjusted by the color shift caused by temperature. This application is not intended to limit the scope of protection of light source components; other colorimetric adjustment methods are also within the scope of protection of this application.

[0061] In one or more embodiments, the light of the second light color emitted when the second light source component 2 is lit alone is as follows: The second light color is positioned within the chromaticity parameter range of the second light function as per vehicle regulations. The second light color is emitted through the first light-emitting surface 3 and independently meets the color requirements of the second light function as per vehicle regulations. Alternatively, the second light color is positioned within the range of the second chromaticity parameters but not within the range of the chromaticity parameters of the second light function as per vehicle regulations. The second light color and the first light color are mixed and emitted as the third light color from the first light-emitting surface 3.

[0062] Specifically, on the one hand, when the second light source component 2 is lit alone, the light emitted, which has a second light color and falls within the chromaticity parameter range of the second light function of the vehicle regulations, can be used to realize the second light function of the optical system. On the other hand, the light emitted by the second light source component 2 with a second light color can include light within the chromaticity parameter range of the second light function of the vehicle regulations and light outside the chromaticity parameter range of the second light function of the vehicle regulations. The portion of the light emitted by the second light source component 2 that has a second light color but not within the chromaticity parameter range of the second light function of the vehicle regulations can be mixed with light of a first light color to form light of a third light color. Therefore, considering that the chromaticity parameter range of the second light function of the vehicle regulations may be unfavorable for color mixing to generate a third light color that meets regulatory requirements, by using a second light source component 2 whose chromaticity parameter range intersects with the second chromaticity parameter range, it is possible to simultaneously satisfy the second and third light functions required by vehicle regulations through chromaticity adjustment.

[0063] In one or more embodiments, the first light source component 1 and / or the second light source component 2 have a first mode and a second mode.

[0064] Control the first light source component 1 and / or the second light source component 2 to be in a first mode, so that the color of the light emitted is within the chromaticity parameter range of the corresponding light function in the vehicle regulations, so as to independently meet the color requirements of the light function in the vehicle regulations. The first light source assembly 1 and / or the second light source assembly 2 are controlled to be in a second mode, so that the color of the light emitted is outside the chromaticity parameter range of the corresponding light function in the vehicle regulations, so as to mix with the light emitted by the other light source assembly and emit light of a third color.

[0065] Specifically, in an embodiment where both the first light source component 1 and the second light source component 2 can be mode-adjusted, when the first light source component 1 and the second light source component 2 are in a first mode, the light of the first light color emitted by the first light source component 1 is within the chromaticity parameter range of the first light function of the vehicle regulations, so as to independently meet the color requirements of the first light function of the vehicle regulations; the light of the second light color emitted by the second light source component 2 is within the chromaticity parameter range of the second light function of the vehicle regulations, so as to independently meet the color requirements of the second light function of the vehicle regulations.

[0066] When the first light source component 1 and / or the second light source component 2 are in the second mode, on the one hand, the light of the first light color emitted by the first light source component 1 is outside the chromaticity parameter range of the first light function in vehicle regulations, and the light of the second light color emitted by the second light source component 2 is also outside the chromaticity parameter range of the second light function in vehicle regulations. The light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 are mixed to generate light of the third light color. On the other hand, if only the first light source component 1 is in the second mode, the light of the first light color emitted by the first light source component 1 is outside the chromaticity parameter range of the first light function in vehicle regulations, while the second light source component 2 is in the first mode, the light of the second light color emitted by the second light source component 2 is within the chromaticity parameter range of the second light function in vehicle regulations. The light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 are mixed to generate light of the third light color. Of course, it is also possible for the first light source component 1 to be in the first mode and the second light source component 2 to be in the second mode, which will not be repeated in this embodiment.

[0067] In some variations, the first light source component 1 and the second light source component 2 may also be embodiments where only one light source component can be mode-adjustable. Taking the first light source component 1 as an example: when the first light source component 1 is in the first mode, the light of the first light color emitted by the first light source component 1 is within the chromaticity parameter range of the first light function of the vehicle regulations, so as to independently meet the color requirements of the first light function of the vehicle regulations.

[0068] When the first light source component 1 is in the second mode, on the one hand, the light of the first light color emitted by the first light source component 1 is outside the chromaticity parameter range of the first light function of the vehicle regulations, and the light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 are mixed to generate light of the third light color to meet the color requirements of the vehicle regulations for the third light function.

[0069] Therefore, when the light from the first light source component 1, which meets the chromaticity parameter range of the first light function in vehicle regulations, and the second light source component 2, which meets the chromaticity parameter range of the second light function in vehicle regulations, is mixed and the color of the light cannot meet the color requirements of the third light function in vehicle regulations, the first light source component 1 and / or the second light source component 2 can be adjusted to a second mode. This ensures that the light emitted by the first light source component 1 and the second light source component 2 in the first mode meets the chromaticity parameter range of the corresponding light function in vehicle regulations. Furthermore, the light emitted by the first light source component 1 and / or the second light source component 2 can be adjusted to be outside the chromaticity parameter range of the corresponding light function in vehicle regulations, so that the mixed light color meets the color requirements of the third light function in vehicle regulations. The mode adjustment method in this application can be the same as the aforementioned chromaticity adjustment method, and will not be repeated here.

[0070] In one or more embodiments, the third light color generated based on the different light output energy ratios between the first light source component 1 and the second light source component 2 has a third chromaticity parameter range, which at least partially overlaps with the chromaticity parameter range of the third light function in vehicle regulations.

[0071] Specifically, when the first light source component 1 and the second light source component 2 are illuminated (e.g., simultaneously, alternately, or in a set sequence), light of the first light color and light of the second light color are mixed to form light of the third light color. The third light color has a third chromaticity parameter range. Light with the third light color can include light rays within the chromaticity parameter range of the third light function of the vehicle regulations and light rays outside the chromaticity parameter range of the third light function of the vehicle regulations. Light that makes the third light color at least partially within the chromaticity parameter range of the third light function of the vehicle regulations, i.e., light that meets the color requirements of the third light function of the vehicle regulations, is used as the third light function of the optical system.

[0072] In one or more embodiments, when the third light color is within the range of fourth chromaticity parameters outside the range of chromaticity parameters for the third light function of vehicle regulations, it serves as an ambient light function.

[0073] The fourth chromaticity parameter range is outside the third chromaticity parameter range. Vehicle regulations do not include ambient lighting functions, and the chromaticity parameter range of ambient lighting does not require regulatory certification. In this embodiment, light of a third light color that is not within the chromaticity parameter range of the third light function in vehicle regulations can be used for exterior ambient lighting.

[0074] In one or more embodiments, the first light source component 1 and the second light source component 2 generate light, and the light output energy ratio between the first light source component 1 and the second light source component 2 is dynamically modulated to synthesize and emit light with a third light color on the first light output surface 3, and the color changes dynamically.

[0075] Specifically, the third light color has a third chromaticity parameter range. The light output energy of the first light source component 1 and the second light source component 2 is dynamically modulated to change the relative light output energy ratio between the two. The light with the third light color formed by mixing the light with the first light color and the light with the second light color can have its chromaticity parameter change continuously or in stages over time within the third chromaticity parameter range. This makes the light with the third light color exhibit the characteristics of dynamic color change, which can be used as a dynamic ambient light function.

[0076] The method of dynamically modulating the light energy ratio between the first light source component 1 and the second light source component 2 includes changing the brightness, luminous intensity, or luminous flux of the first light source component 1 and / or the second light source component 2 when the first light source component 1 and the second light source component 2 are lit simultaneously; and changing the alternating emission frequency and emission time distribution ratio of the first light source component 1 and / or the second light source component 2 when the first light source component 1 and the second light source component 2 are lit alternately or in a set sequence. The alternating emission or lighting in a set sequence of the first light source component 1 and the second light source component 2 can be achieved by controlling the first light source component 1 and the second light source component 2 to light up at a preset flashing frequency through a PWM control signal.

[0077] In one or more embodiments, the third light color generated based on the different light output energy ratios between the first light source component 1 and the second light source component 2 has a third chromaticity parameter range, and the third chromaticity parameter range also at least partially overlaps with the chromaticity parameter range of the fourth light function in vehicle regulations. The light of the third light color located within the chromaticity parameter range of the fourth light function can also meet the requirements of the fourth light function in vehicle regulations.

[0078] Specifically, when the first light source component 1 and the second light source component 2 are lit (e.g., simultaneously, alternately, or in a set sequence), the light of the first and second light colors is mixed to form light of the third light color. The chromaticity parameters of the third light color are at least partially within the chromaticity parameter range of the third light function and the fourth light function of the vehicle regulations. Light that meets the color requirements of the third light function of the vehicle regulations is used as the third light function of the optical system, and light that meets the color requirements of the fourth light function of the vehicle regulations is used as the fourth light function of the optical system. In one embodiment, the light emitted by the first light source component 1 is red light, and the light emitted by the second light source component 2 is blue-green light. The red light and blue-green light are mixed to form white light, which is then used normally as the third light function of the optical system. Furthermore, by adjusting the optical parameters of the first light source component 1, the light emitted by the first light source component 1 is made to be red light (with chromaticity coordinates biased towards orange light). The red light and blue-green light are mixed to form amber light, which is then used as the fourth light function of the optical system.

[0079] In one or more embodiments, the first light source assembly 1 includes: a first light source capable of emitting light of a first color; or a second light source and a first color-filtering optical element, wherein light emitted by the second light source, after passing through the first color-filtering optical element, can emit light of the first color. The second light source assembly 2 includes: a third light source capable of emitting light of a second color; or a fourth light source and a second color-filtering optical element, wherein light emitted by the fourth light source, after passing through the second color-filtering optical element, can emit light of the second color. Specifically, the first light source assembly 1 and the second light source assembly 2 may share the same color-filtering optical element 102, the color-filtering optical element 102 forming a color-filtering unit array, the color-filtering unit array filtering different colors of light corresponding to the first light source assembly 1 and the second light source assembly 2 respectively.

[0080] Specifically, such as Figure 3 As shown, the light emitted from the light-emitting surfaces of the first light source assembly 1 and the second light source assembly 2 can be directly provided by the light source body 101, or by a combination of the light source body 101 and the color filter optical element 102. 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., and this embodiment does not impose specific limitations. The embodiment that directly uses the light source body 101 reduces the number of parts and lowers costs. In the embodiment that uses the light source body 101 and the color filter optical element 102, different light colors can be achieved using only one color light source in conjunction with different color filter optical elements 102, offering greater flexibility.

[0081] In one or more embodiments, the first light source assembly 1 and the second light source assembly 2 are each provided with at least one light source. The independently packaged light sources in the first light source assembly 1 and the second light source assembly 2 are arranged on the same circuit board 105, or respectively arranged on different circuit boards 105. Alternatively, the light source jointly packaged in the first light source assembly 1 and the second light source assembly 2 is arranged on a single circuit board 105.

[0082] Specifically, such as Figures 4 to 7As shown, the light sources in the first light source assembly 1 and the second light source assembly 2 are LEDs. The first LED 103 in the first light source assembly 1 and the second LED 104 in the second light source assembly 2 can be independently packaged, and the independently packaged first LED 103 and second LED 104 can be arranged on the same circuit board 105 or on different circuit boards 105 according to assembly requirements. Alternatively, the first LED 103 in the first light source assembly 1 and the second LED 104 in the second light source assembly 2 can be co-packaged, with the co-packaged first LED 103 and second LED 104 arranged on a single circuit board 105. The number of co-packaged first LEDs 103 and second LEDs 104 can be set as needed. By allocating the number of co-packaged first LEDs 103 and second LEDs 104, the third light color can be achieved simply by lighting LEDs in the same package, without the need for circuit control or other adjustments.

[0083] In one or more embodiments, the optical system further includes a first optical component 4, through which the first light source component 1 and the second light source component 2 emit light. The first optical component 4 includes an optical element, which is a light guide element or a reflective element; or, the optical element forms a light guide channel. The light guide channel can be used to achieve pixelated display.

[0084] like Figure 1 As shown, the first light source component 1 and the second light source component 2 are disposed at the light-incident end of the light guide element, the reflective element, or the light guide channel. The light of the first color emitted by the first light source component 1 and the light of the second color emitted by the second light source component 2 can be mixed through the light guide element, the reflective element, or the light guide channel, and emitted as light of the third color from the light-out end of the light guide element, the reflective element, or the light guide channel.

[0085] In one or more embodiments, the optical system further includes a second optical component 5, through which the first light source component 1 and the second light source component 2 emit light. The second optical component 5 includes at least two optical elements, which are any combination of light guide elements and reflective elements; or, the at least two optical elements form a light guide channel. The light guide channel can be used to achieve pixelated display.

[0086] like Figure 2 As shown, the first light source assembly 1 and the second light source assembly 2 are disposed at the light-incident end of the light guide element and / or the combination element with the reflective element and / or the light guide channel. The light of the first color emitted by the first light source assembly 1 and the light of the second color emitted by the second light source assembly 2 can be mixed through the light guide element and / or the combination element with the reflective element and / or the light guide channel, and emitted as light of the third color from the light-out end of the light guide element and / or the combination element with the reflective element and / or the light guide channel.

[0087] In one or more embodiments, the light guide element is any one of the following: light guide 501, light guide plate 507, thick wall 502, condenser, and light distribution lens 503. The thick wall 502 may include a direct-projection thick wall, a reflective thick wall 5011, or other irregularly shaped thick walls. A direct-projection thick wall may be a thick wall with an incident light surface and an exit light surface facing each other. A reflective thick wall 5011 may be a thick wall where light incident on the incident light surface is reflected by one or more reflective surfaces and then exits through the exit light surface. The condenser may include a reflective condenser 505 and a direct-projection condenser 504. This embodiment does not limit the specific structure of the light guide element.

[0088] Specifically, such as Figure 8 As shown, in one embodiment, taking the optical component as a combination of a light guide 501 and a thick wall 502 or a light distribution lens 503 as an example, the first light source component 1 and the second light source component 2 are disposed at the light-incident end of the light guide 501. The light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 pass through the light guide 501 and the thick wall 502 or through the light guide 501 and the light distribution lens 503, and after being mixed in the light guide 501, the thick wall 502 or the light distribution lens 503, the light of the third light color is emitted from the light-out surface of the thick wall 502 or the light distribution lens 503, so as to realize the third light function of the optical system. A bracket 601 can also be provided in the optical component to fix the combination of the light guide 501 and the thick wall 502 or the light distribution lens 503. A reflective coating can be provided on the surface of the bracket 601 facing the light guide 501 to improve light utilization.

[0089] like Figure 9As shown, in one embodiment, the optical components are a combination of a thick-walled 502 and a direct-firing condenser 504, and / or a reflective condenser 505, and / or a reflector 506. In one implementation, the first light source component 1 and the second light source component 2 are disposed at the light-incident end of the direct-firing condenser 504, the reflective condenser 505, or the reflector 506. The light emitted by the first light source component 1 of a first color and the light emitted by the second light source component 2 of a second color pass through the direct-firing condenser 504 and the thick-walled 502, or through the reflective condenser 505 and the thick-walled 502, or through the reflector 506 and the thick-walled 502. After the light is mixed in the thick-walled 502 with the direct-firing condenser 504, or with the reflective condenser 505, or with the reflector 506, it is emitted from the light-exiting surface of the thick-walled 502 as light of a third color, thereby realizing the third light function of the optical system. In another implementation, the first light source assembly 1 and the second light source assembly 2 can be independently disposed at the light-incident end of the direct-firing condenser 504, the reflective condenser 505, or the reflector 506. For example, the first light source assembly 1 is disposed at the light-incident end of the direct-firing condenser 504, and the light of the first color emitted by the first light source assembly 1 passes through the direct-firing condenser 504 and the thick wall 502; the second light source assembly 2 is disposed at the light-incident end of the reflective condenser 505, and the light of the second color emitted by the second light source assembly 2 passes through the reflective condenser 505 and the thick wall 502. Subsequently, the two colors of light are mixed in the thick wall 502 and emitted from the light-emitting surface of the thick wall 502 as light of the third color, thereby realizing the third light function of the optical system. This application can also realize more combinations, which will not be elaborated here. Among them, a decorative ring 602 can also be provided at the light-emitting end of the thick wall 502 in the optical assembly to shield the structure of the internal space.

[0090] like Figure 10 As shown, in one embodiment, taking the optical components as a combination of a reflector 506 and a thick wall 502 or a light-distributing lens 503 as an example, the first light source component 1 and the second light source component 2 are disposed at the light-incident end of the reflector 506. The light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 pass through the reflector 506 and the thick wall 502 or through the reflector 506 and the light-distributing lens 503, and after the light is mixed in the reflector 506, the thick wall 502 or the light-distributing lens 503, it is emitted from the light-exiting surface of the thick wall 502 or the light-distributing lens 503 as light of the third light color, so as to realize the third light function of the optical system.

[0091] like Figure 11As shown, in one embodiment, taking a light guide plate 507 as an example, the first light source component 1 and the second light source component 2 are disposed at the light-incident end of the light guide plate 507. The light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 pass through the light guide plate 507 and are mixed in the light guide plate 507 before being emitted as light of the third light color from the light-out surface of the light guide plate 507, thereby realizing the third light function of the optical system. A white dielectric layer 603 can also be disposed on the side of the light guide plate 507 opposite to its light-out surface to serve as a background layer, improving the visual integrity of the optical system when it is lit and the appearance consistency when it is not lit, thus enhancing the perceived quality of the optical system. A bracket 601 can also be disposed in the optical component to fix the light guide plate 507.

[0092] like Figure 12 As shown, in one embodiment, taking an integrated reflective thick-walled component 508 with dual light-incident ends and a light-distributing lens 503 as an example, the first light source component 1 and the second light source component 2 are respectively disposed at the first light-incident end and the second light-incident end of the integrated reflective thick-walled component 508 with dual light-incident ends. The light of the first color emitted by the first light source component 1 is emitted from the main light-emitting direction of the optical component after passing through the first reflective surface of the integrated reflective thick-walled component 508 with dual light-incident ends. The light of the second color emitted by the second light source component 2 is emitted from the main light-emitting direction of the optical component after passing through the second reflective surface of the integrated reflective thick-walled component 508 with dual light-incident ends. After the two different colors of light are mixed in the integrated reflective thick-walled component 508 with dual light-incident ends, they are emitted from the light-emitting surface of the integrated reflective thick-walled component 508 with dual light-incident ends. After passing through the light-distributing lens 503, they are emitted from the light-emitting surface of the light-distributing lens 503 as light of the third color, so as to realize the third light function of the optical system. The optical assembly may also include a bracket 601 to fix the combination of the integrated reflective thick-walled component 508 with dual light-incident ends and the light-distributing lens 503.

[0093] like Figure 13As shown, in one embodiment, taking an optical component consisting of a first reflective thick-walled 509, a second reflective thick-walled 5010, and a light-distributing lens 503 as an example, the first reflective thick-walled 509 and the second reflective thick-walled 5010 are arranged front and back along the main light-emitting direction of the optical component. The first light source component 1 is located at the light-incident end of the first reflective thick-walled 509. Light of the first color emitted by the first light source component 1 is reflected by the first reflective thick-walled 509 and emitted in the main light-emitting direction of the optical component. The second light source component 2 is located at the light-incident end of the second reflective thick-walled 5010. At the end, the second light source component 2 emits light of the second color, which is reflected by the second reflective thick wall 5010 and emitted in the main light-emitting direction of the optical component. The light then enters the first reflective thick wall 509 after exiting the light-emitting surface of the second reflective thick wall 5010. The two different colors of light are mixed in the first reflective thick wall 509 and then exit from the light-emitting surface of the first reflective thick wall 509. After passing through the light-distributing lens 503, the light of the third color is emitted from the light-distributing lens 503, thus realizing the third light function of the optical system. A bracket 601 can also be provided in the optical component to fix the combination of the reflective thick wall and the light-distributing lens 503.

[0094] like Figure 14 As shown, in one embodiment, taking the optical components as a reflective thick-walled 5011, a reflector 506, and a light-distributing lens 503 as an example, the reflective thick-walled 5011 and the reflector 506 are arranged back and forth along the main light-emitting direction of the optical components. The first light source component 1 is located at the light-incident end of the reflective thick-walled 5011. The light of the first color emitted by the first light source component 1 is reflected by the reflective surface of the reflective thick-walled 5011 and emitted in the main light-emitting direction of the optical components. The second light source component 2 is located at the light-incident end of the reflector 506. The light of the second color emitted by the second light source component 2 is reflected by the reflector 506 and emitted in the main light-emitting direction of the optical components. The reflected light enters the reflective thick-walled 5011. After the two different colors of light are mixed in the reflective thick-walled 5011, they are emitted from the light-emitting surface of the reflective thick-walled 5011. After passing through the light-distributing lens 503, they are emitted from the light-distributing lens 503 as light of the third color, so as to realize the third light function of the optical system. The optical components may also include a bracket to fix the combination of the reflective thick-walled 5011, the reflector 506 and the light distribution lens 503.

[0095] like Figure 15As shown, in one embodiment, taking an integrated reflective focusing device 5012 with dual light-incident ends and a thick-walled structure 502 as an example, the first light source component 1 and the second light source component 2 are respectively disposed at the first light-incident ends and the second light-incident ends of the integrated reflective focusing device 5012 with dual light-incident ends. The light of the first color emitted by the first light source component 1 is emitted towards the main light-emitting direction of the optical component after passing through the first reflective surface of the integrated reflective focusing device 5012 with dual light-incident ends. The light of the second color emitted by the second light source component 2 is emitted towards the main light-emitting direction of the optical component after passing through the second reflective surface of the integrated reflective focusing device 5012 with dual light-incident ends. After the two different colors of light are mixed in the integrated reflective focusing device 5012 with dual light-incident ends and the thick-walled structure 502, the light of the third color is emitted from the light-emitting surface of the thick-walled structure 502, thereby realizing the third light function of the optical system. A decorative ring 602 may also be provided at the light-emitting end of the thick-walled structure 502 in the optical component to shield the internal space structure.

[0096] This application can also realize more combinations of optical components, which will not be elaborated here.

[0097] In one or more embodiments, the optical action site of the optical element is provided with optical microstructures, surface textures and / or scattering media.

[0098] Specifically, optical microstructures, surface textures, and / or scattering media can be set at optical action positions such as the light-incident surface, reflecting surface, and light-emitting surface of optical elements to diffuse, scatter, refract, reflect, homogenize, or redistribute light, thereby improving the light emission uniformity of the optical system, adjusting the light emission angle distribution, or achieving a preset optical effect. The optical microstructures can include microprism structures, microlens structures, microreflection structures, or other microscale optical structures; the surface textures can include matte textures, skin textures, random textures, or regular textures; and the scattering media can be a material layer containing scattering particles or a film layer with scattering function. This embodiment does not limit these limitations. Furthermore, the optical microstructures, surface textures, and / or scattering media can be set for different light source components to modulate the light emitted by the first and second light source components differently before or during color mixing, improving color mixing accuracy and efficiency. In embodiments where the first light source component 1 and the second light source component 2 are set at different light-incident ends, different optical microstructures, surface textures, and / or scattering media can be set at the corresponding light-incident ends of the first and second light source components 1 and 2. For example, different optical microstructures, surface textures, and / or scattering media can be provided in the respective optical paths of the first light source assembly 1 and the second light source assembly 2. Many more variations can be achieved in this application, which will not be elaborated upon here.

[0099] In one or more embodiments, light emitted by the first light source component 1 and the second light source component 2 can be incident on the optical component from the same light-incident end; or light emitted by the first light source component 1 and the second light source component 2 can be incident on the optical component from the first light-incident end 701 and the second light-incident end 702 of the optical component respectively, and the optical component is provided with a light mixing part 703 connecting its first light-incident end 701, second light-incident end 702 and light-out end.

[0100] Specifically, such as Figures 16 to 17 As shown, taking the optical component as a light guide 501 as an example, the light guide 501 has a first light-incident end 701 and a second light-incident end 702 arranged on the same side or different sides facing the first light source component 1 and the second light source component 2. The first light source component 1 is located at the first light-incident end 701 of the light guide 501 and emits light of a first color. The second light source component 2 is located at the second light-incident end 702 of the light guide 501 and emits light of a second color. After the two different colors of light are mixed in the light mixing section 703 of the light guide 501, they are emitted from the light-exiting surface 704 of the light guide 501 as light of a third color, so as to realize the third light function of the optical system.

[0101] In one or more embodiments, the optical system may include a third optical component, which is an imaging element through which light of a third color is emitted into external space. The imaging element is any one of LCD (Liquid Crystal Display), DMD (Digital Micromirror Device), and LCOS (Liquid Crystal on Silicon). Thus, pixelated display of each optical function is achieved through the third optical component.

[0102] In one or more embodiments, the first light source component 1 and the second light source component 2 emit light through the same first light-emitting surface 3. The light of the first light color emitted when the first light source component 1 is lit alone is emitted through the first light-emitting surface 3 and combined with other light source components to meet the color requirements of the first light function in vehicle regulations. The optical system also includes a fourth light source component that emits light of a fourth light color. The fourth light source component is lit simultaneously with the first light source component 1, so that the light of the fourth light color is emitted through the second light-emitting surface 8 to compensate for the light of the first light color. The light emitted by the first light source component 1 and the fourth light source component is combined to meet the color requirements of the first light function in vehicle regulations.

[0103] Specifically, the light emitted by the first light source component 1 when it is lit alone is only partially satisfied with the light color requirements of the first light function in vehicle regulations. Therefore, a fourth light source component is configured to emit light of a fourth light color. The light of the fourth light color is used to compensate for the light of the first light color in order to generate a mixed light that fully satisfies the light color requirements of the first light function in vehicle regulations.

[0104] In one or more embodiments, the first light source component 1 and the second light source component 2 emit light through the same first light-emitting surface 3. When the second light source component 2 is lit alone, the light of the second light color emitted is emitted through the first light-emitting surface 3 and combined with other light source components to meet the color requirements of the second light function in vehicle regulations. The optical system also includes a fifth light source component that emits light of the fifth light color. The fifth light source component and the second light source component 2 are lit simultaneously, so that the light of the fifth light color is emitted through a third light-emitting surface to compensate for the light of the second light color. The light emitted by the second light source component and the fifth light source component is combined to meet the color requirements of the second light function in vehicle regulations.

[0105] Specifically, the second light color emitted by the second light source component 2 when it is lit alone only partially meets the requirements of the vehicle regulation for the color of the second light function. Therefore, a fifth light source component is configured to emit light of the fifth light color. The light of the fifth light color compensates for the light of the second light color to generate a mixed light that fully meets the requirements of the vehicle regulation for the color of the second light function.

[0106] The light compensation methods include spectral compensation, such as using the fourth / fifth light color to supplement the relatively insufficient bands in the spectrum of the first / second light color, so that the spectral distribution of the mixed light is closer to the target color; chromaticity compensation, such as by introducing the fourth / fifth light color to shift the color coordinates of the mixed light, so that the color of the mixed light falls into the target chromaticity range; and brightness compensation, such as the fourth / fifth light color increasing the overall brightness of the mixed light or compensating for the insufficient brightness of a certain color channel, etc. This embodiment does not limit these methods.

[0107] The light source component used for compensation can be provided with a second light-emitting surface 8 and a third light-emitting surface independent of the first light-emitting surface 3.

[0108] In one or more embodiments, the distance between the second light-emitting surface 8 and the first light-emitting surface 3 is less than 10 cm; and / or, the distance between the third light-emitting surface and the first light-emitting surface 3 is less than 10 cm.

[0109] By maintaining a small distance between the second light-emitting surface 8 and the first light-emitting surface 3, and / or between the third light-emitting surface and the first light-emitting surface 3, the light from the two light-emitting surfaces can more easily form a full superposition and mixing in space during propagation, so that the observer perceives a single composite color at a normal viewing distance, improving the consistency and uniformity of light color, and avoiding the formation of different color distinctions and bright and dark areas in the light.

[0110] In one or more embodiments, the second light-emitting surface 8 surrounds the first light-emitting surface 3, or the second light-emitting surface 8 and the first light-emitting surface 3 are alternately arranged; and / or, the third light-emitting surface surrounds the first light-emitting surface 3, or the third light-emitting surface and the first light-emitting surface 3 are alternately arranged.

[0111] like Figures 18 to 19 As shown, taking the distribution of the first light-emitting surface 3 and the second light-emitting surface 8 as an example, by arranging the two light-emitting surfaces in a surrounding or alternating manner, the distribution of light of different colors in space is more uniform, which can effectively improve the uniformity of the light color and the mixing efficiency of the mixed light. At the same time, even if the observer's viewing angle changes, the mixed light of different colors can still be received after being mixed in a relatively stable proportion, thereby improving the stability of the light color of the mixed light when observed from different viewing angles.

[0112] In one or more embodiments, the light of the fourth color emitted when the fourth light source component is lit alone is emitted through the second light-emitting surface 8 and serves as an ambient light; the light of the fifth color emitted when the fifth light source component is lit alone is emitted through the third light-emitting surface and serves as an ambient light.

[0113] Specifically, when the fourth light source component is lit alone, the emitted light of the fourth color can be used to realize the ambient lighting function of the optical system; when the fifth light source component is lit alone, the emitted light of the fifth color can be used to realize the ambient lighting function of the optical system.

[0114] In one or more embodiments, the second light-emitting surface 8 and the third light-emitting surface are the same light-emitting surface, which not only simplifies the composition of the optical system, but also enables more colors to be displayed and more dynamic displays through the mixing of light emitted by the fourth and fifth light-emitting components. Furthermore, in some embodiments, the light emitted by the fourth and fifth light-emitting components can meet the color requirements of vehicle regulations for corresponding lighting functions.

[0115] In one or more embodiments, the range of the first chromaticity parameter of the first light color in the chromaticity diagram is: x: 0.429 to 0.545; y: 0.382 to 0.482.

[0116] In one or more embodiments, the x-axis coordinate of the first light color in the chromaticity diagram can be 0.429, 0.433, 0.458, 0.479, 0.505, 0.524, or 0.545; the y-axis coordinate of the first light color in the chromaticity diagram can be 0.382, 0.401, 0.423, 0.458, 0.472, or 0.482. Furthermore, the first light source component 1 can be adjusted to be located outside the range of the first chromaticity parameters. Alternatively, the chromaticity parameter range of the first light source component 1 can partially overlap with the aforementioned range of the first chromaticity parameters. This application can achieve many more variations, which will not be elaborated here.

[0117] In one or more embodiments, the range of the second chromaticity parameter of the second light color in the chromaticity diagram is: x: 0.013 to 0.21; y: 0.2 to 0.494.

[0118] In one or more embodiments, the x-axis coordinate of the second light color in the chromaticity diagram can be 0.013, 0.028, 0.059, 0.082, 0.108, 0.145, 0.179, or 0.21; the y-axis coordinate of the second light color in the chromaticity diagram can be 0.2, 0.225, 0.258, 0.283, 0.321, 0.348, 0.372, 0.399, 0.428, 0.459, or 0.494. Furthermore, the second light source component 2 can also be adjusted to be located outside the range of the second chromaticity parameters. Alternatively, the chromaticity parameter range of the second light source component 2 can partially overlap with the aforementioned range of the second chromaticity parameters. This application can achieve many more variations, which will not be elaborated here.

[0119] In one or more embodiments, such as Figure 20 As shown, the vertex coordinates of the second chromaticity parameter range of the second light color in the chromaticity diagram include: T1 (x: 0.013, y: 0.494); T2 (x: 0.2, y: 0.4); T3 (x: 0.2, y: 0.2); T4 (x: 0.013, y: 0.2); T5 (x: 0.013, y: 0.320).

[0120] This ensures that the first light color, the second light color, and the third light color formed by mixing the first light color and the second light color independently meet the color requirements of vehicle regulations for the first light function, the second light function, and the third light function, or together with other light source components, meet the color requirements of the corresponding light function in vehicle regulations.

[0121] In one or more embodiments, the optical system further includes at least one sixth light source component that emits light of a sixth color when lit alone.

[0122] The light of the first light color emitted by the first light source component 1, the light of the second light color emitted by the second light source component 2, and the light of the sixth light color emitted by the sixth light source component, any two or three light colors, mixed in different combinations and with different output energy ratios, can be emitted as light of different colors and can be used for different light functions of the optical system.

[0123] Specifically, the sixth light source component can emit light of a sixth color different from the first and second light colors. Besides the mixing of light emitted by the first and second light source components 1 and 2, the sixth light source component can also mix with the light emitted by the first / second light source components 1, or the light emitted by the sixth, first, and second light source components 2, to achieve the color requirements of the vehicle's regulatory light functions. In this embodiment, the first light color is, for example, amber, the second light color is, for example, blue-green, and the sixth light color is, for example, blue, thus allowing for different combinations and different energy ratios of color mixing. The light emitted by the sixth light source component can meet the color requirements of the vehicle's regulatory light functions. For example, in one embodiment, the first light color emitted by the first light source component 1 is used for the turn signal function, the second light color emitted by the second light source component 2 is used for the driver automation system marker light function, the sixth light color emitted by the sixth light source component is used for the front position light function, and the mixture of the first, second, and sixth light colors is used for the daytime running light function. This application can achieve many more variations, which will not be elaborated here.

[0124] In one or more embodiments, when the first light source component 1 is lit alone, it emits light of a first light color, independently meeting the color requirements of the first light function in vehicle regulations; when the second light source component 2 is lit alone, it emits light of a second light color, independently meeting the color requirements of the second light function in vehicle regulations. The light of the first light color emitted by the first light source component 1, the light of the second light color emitted by the second light source component 2, and the light of the sixth light color emitted by the sixth light source component are mixed and emitted as light of a third light color, such that the light of the third light color meets the color requirements of the third light function in vehicle regulations. In this embodiment, the light of the sixth light color emitted by the sixth light source component can be used as an ambient light, thus being suitable for mixing with the light of the first light color and the light of the second light color to emit light of the third light color that meets the color requirements of the third light function in vehicle regulations. The sixth light color is preferably blue.

[0125] Furthermore, the sixth light source component may have the same or different structure as the aforementioned first light source component 1 and second light source component 2, and this application is not limited thereto. The first light source component 1, the second light source component 2, and the sixth light source component can emit light from the same light-emitting surface. In some variations, the first light source component 1 and the second light source component 2 can emit light from the same light-emitting surface, then mix with the light emitted by the sixth light source component before emitting light from another light source; or the first light source component 1 and the sixth light source component can emit light from the same light-emitting surface, then mix with the light emitted by the second light source component 2 before emitting light from another light source; or the second light source component 2 and the sixth light source component can emit light from the same light-emitting surface, then mix with the light emitted by the first light source component 1 before emitting light from another light source. The sixth light source component may share a light-incident surface with the first light source component 1 and / or the second light source component 2, or the sixth light source component may pass through different light-incident surfaces than the first light source component 1 and / or the second light source component 2. The sixth light source assembly is similarly applicable to the first light source assembly 1 and the second light source assembly 2 described above, as well as to various optical elements or imaging components listed in the embodiments of this application and those not listed in this application. This application can implement many more variations, which will not be elaborated here.

[0126] Based on the same concept, a second aspect of the embodiments of this application provides a control method for controlling an optical system as described in any of the above-described embodiments, wherein at least one of the first light source component 1 and the second light source component 2 has a mode switching function, and the control method includes: The light source component with mode switching function in the first light source component 1 and the second light source component 2 is controlled to be in the first mode. In the first mode, the color of the light emitted is within the chromaticity parameter range of the corresponding light function in the vehicle regulations. The light source component with mode switching function in the first light source component 1 and the second light source component 2 is controlled to be in the second mode. In the second mode, the color of the light emitted is within or outside the chromaticity parameter range of the corresponding light function of the vehicle regulations, so that at least the light of the first light color and the light of the second light color are mixed and emitted as light of the third light color, and the light of the third light color meets the color requirements of the third light function of the vehicle regulations.

[0127] In embodiments where both the first light source component 1 and the second light source component 2 can be mode-switched, on one hand, the first light source component 1 and the second light source component 2 are controlled to be in a first mode, where the color of the emitted light is within the chromaticity parameter range of the corresponding light function according to vehicle regulations. The individual on / off states of the first light source component 1 and the second light source component 2 are controlled to achieve switching between the first and second light functions and the generation of corresponding light. On the other hand, the first light source component 1 and / or the second light source component 2 are controlled to be in a second mode, where the color of the emitted light is within or outside the chromaticity parameter range of the corresponding light function according to vehicle regulations. The light of the first light color and the light of the second light color are combined at the light-emitting surface of the optical component and emitted as light of a third light color, which is used for the third light function.

[0128] Specifically, on the one hand, the first light source assembly 1 and the second light source assembly 2 are controlled to be in a first mode, so that the light of the first light color emitted by the first light source assembly 1 is within the chromaticity parameter range of the first light function of the vehicle regulations, so as to independently meet the color requirements of the first light function of the vehicle regulations; the light of the second light color emitted by the second light source assembly 2 is within the chromaticity parameter range of the second light function of the vehicle regulations, so as to independently meet the color requirements of the second light function of the vehicle regulations. By controlling the individual on / off state of the first light source assembly 1 and the second light source assembly 2, the first light function and the second light function are switched.

[0129] On the other hand, controlling the first light source component 1 and / or the second light source component 2 to be in a second mode, as in one embodiment, controlling both the first light source component 1 and the second light source component 2 to be in the second mode, such that the light of a first light color emitted by the first light source component 1 is outside the chromaticity parameter range of the first light function in vehicle regulations, and the light of a second light color emitted by the second light source component 2 is outside the chromaticity parameter range of the second light function in vehicle regulations, and a third light color is generated by mixing the first light color and the second light color. In another embodiment, controlling either the first light source component 1 or the second light source component 2 to be in the second mode, and the other light source component to be in the first mode, such that the first light color emitted by the first light source component 1 is outside the chromaticity parameter range of the first light function in vehicle regulations, and the second light source component 2 to be in the first mode, such that the second light color emitted by the second light source component 2 is within the chromaticity parameter range of the second light function in vehicle regulations, and a third light color is generated by mixing the first light color and the second light color, so that the mixed light color meets the color requirements of the third light function in vehicle regulations.

[0130] In some variations, only one of the first light source component 1 and the second light source component 2 may be able to switch modes. Taking the first light source component 1 as an example, when the first light source component 1 is in the first mode, the light of the first light color emitted by the first light source component 1 is within the chromaticity parameter range of the first light function of the vehicle regulations, so as to independently meet the color requirements of the first light function of the vehicle regulations.

[0131] When the first light source component 1 is in the second mode, on the one hand, the light of the first light color emitted by the first light source component 1 is outside the chromaticity parameter range of the first light function in vehicle regulations. The light of the first light color emitted by the first light source component 1 and the light of the second light color emitted by the second light source component 2 are mixed to generate light of the third light color, thereby satisfying the color requirements of the third light function in vehicle regulations. This application can achieve many more variations, which will not be elaborated here.

[0132] In one or more embodiments, controlling the light source component with mode switching function in the first light source component 1 and the second light source component 2 to be in the second mode further includes: The chromaticity parameters of the third light color are changed by modulating the light energy ratio between the first light source component 1 and the second light source component 2 using a PWM control signal.

[0133] Specifically, the first light source component 1 can be controlled to flicker by a first PWM control signal, and the second light source component 2 can be controlled to flicker by a second PWM control signal. Through the PWM control signals, the first light source component 1 and the second light source component 2 are controlled to light up alternately; that is, the first PWM control signal and the second PWM control signal are complementary high and low level signals, causing the light of the first and second light colors to mix under human eye perception, forming the light of the third light color. In this embodiment, based on the different duty cycle settings of the first and second PWM control signals, the mixed third light color has a third chromaticity parameter range, which at least partially overlaps with the chromaticity parameter range of the third light function in vehicle regulations. Duty cycle refers to the proportion of time the signal is at an effective level (e.g., high level) within a complete PWM control signal cycle. Taking the first and second PWM control signals with high level as the effective level as an example, the larger the duty cycle of the first PWM control signal, the smaller the duty cycle of the second PWM control signal, the longer the first light source component 1 is lit within one cycle, and the shorter the lit time of the second light source component 2 is within one cycle. Conversely, the smaller the duty cycle of the first PWM control signal, the larger the duty cycle of the second PWM control signal, the shorter the lit time of the first light source component 1 is within one cycle, and the longer the lit time of the second light source component 2 is within one cycle. The duty cycle adjustment range is 0-100%. When the duty cycle is 0%, it means that the corresponding light source component is always off; when the duty cycle is 100%, it means that the corresponding light source component is always lit. This allows for the adjustment of the light output energy ratio between the first light source component 1 and the second light source component 2, thereby changing the chromaticity parameters of the third light color, which is a mixture of the first and second light colors. It also allows for dynamic modulation of the duty cycle between the first and second PWM control signals, enabling the third light color to exhibit dynamic color change characteristics.

[0134] In one or more embodiments, controlling the light source component with mode switching function in the first light source component 1 and the second light source component 2 to be in the second mode further includes: The chromaticity parameters of the third light color are changed by modulating the light output energy ratio among the first light source component 1, the second light source component 2, and the sixth light source component using a PWM control signal.

[0135] Specifically, the first light source component 1 can be controlled to flicker by a first PWM control signal, the second light source component 2 can be controlled to flicker by a second PWM control signal, the mixed color light from the first light source component 1 and the second light source component 2 can be controlled to flicker by a third PWM control signal, and the sixth light source component can be controlled to flicker by a fourth PWM control signal. The PWM control signals control the first light source component 1 and the second light source component 2 to light up alternately, meaning the first and second PWM control signals are complementary high and low level signals, causing the light of the first and second colors to mix under human perception, forming mixed color light. The third PWM control signal controls the mixed color light and the sixth light source component to light up alternately, meaning the third and fourth PWM control signals are complementary high and low level signals, causing the mixed color light and the sixth color light to mix under human perception, forming a third color light. The duty cycles of the first to fourth PWM control signals can be modulated to achieve a dynamic third color light or a third color light different from the aforementioned. This application can achieve many variations; the aforementioned complementary high and low level signals may have dead zones, but this application is not limited to these.

[0136] Based on the same concept, a third aspect of the present application provides a vehicle lighting fixture, including the optical system described above.

[0137] Based on the same concept, a fourth aspect of the present application provides a vehicle including the vehicle lights described above.

[0138] 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.
