Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a variable color temperature automotive lighting module and vehicle. Background Technology

[0002] With the iterative upgrades of automotive lighting technology, LED (light-emitting diode) headlights, thanks to their excellent comprehensive lighting performance, have been widely used in various passenger vehicles and have become the mainstream in-vehicle lighting configuration. Currently, the color temperature of mass-produced LED headlights has generally been increased to 6000K, making the light color closer to natural white light. In normal driving scenarios on dry asphalt roads, they have the advantages of sufficient brightness, clear road imaging, and transparent vision, which can effectively optimize driving visibility under normal road conditions and meet the basic lighting needs of drivers for daily commuting and transportation.

[0003] However, high color temperature LED headlights have a high peak value for short-wave blue light in their spectrum, while the proportion of yellow and red light bands is relatively low. When vehicles are driving in the rain, the water film on the road surface will form a specular reflection, and short-wave blue light will be easily reflected, which can easily cause problems such as strong road surface reflection, whitening, watermark glare, and road surface glare, making road details blurry and interfering with the driver's accurate judgment of road conditions.

[0004] Furthermore, in rainy, foggy, and dusty weather, the water mist and dust particles suspended in the air will strongly scatter short-wave blue light, causing LED headlights to easily exhibit severe scattering and beam divergence, significantly shortening the effective illumination distance, reducing the driver's effective field of vision and decreasing visual clarity, which greatly reduces driving safety in adverse weather conditions. Summary of the Invention

[0013] As an optional implementation, the first optical element includes a lens; The second optical element includes at least one of a condenser, a silicone needle, a small reflector, and a silicone head.

[0014] As an optional implementation, the variable color temperature automotive lighting module further includes: A circuit board, wherein the LED light source array is disposed on the circuit board; A heat sink is disposed on the side of the circuit board opposite to the LED light source array.

[0015] As an optional implementation, the drive control unit has a first lighting mode and a second lighting mode; In the first lighting mode, the drive control unit controls the first LED to emit light in order to form the main light pattern; In the second lighting mode, the drive control unit controls the first LED and the second LED to emit light, and adjusts the light output ratio of the first LED and the second LED to adjust the color temperature of the superimposed main light pattern and the color temperature compensation light pattern.

[0016] As an optional implementation, the central focusing unit and the edge focusing unit are each composed of at least one of a condenser, a small reflector, a silicone head, and a silicone needle.

[0017] As an optional implementation, the light distribution component extends along the arrangement direction of the LED light source array and has a light source side profile facing the LED light source array and a light emitting side profile facing away from the LED light source array. The light-emitting side profile includes a central light-emitting profile segment located in the middle of the light distribution assembly and multiple side light-emitting profile segments located on both sides of the central light-emitting profile segment. The central light-emitting surface segment protrudes relative to the side light-emitting surface segment along the direction away from the LED light source array. Multiple side light-emitting surface segments gradually approach the LED light source array from the middle of the light distribution component to both ends, so that the light-emitting side surface forms a segmented stepped curved surface that protrudes in the middle and gradually decreases on both sides.

[0018] As an optional implementation, the light source side profile includes a plurality of focusing profile units arranged sequentially along the arrangement direction of the LED light source array; Each of the light-concentrating surface units protrudes toward the corresponding first LED or second LED, and adjacent light-concentrating surface units are connected by a transition surface that is recessed away from the LED light source array, so that the light source side surface forms a continuous concave-convex profile.

This can stably maintain sufficient road illuminance and clear road imaging effect under normal road conditions, meeting the lighting needs of daily commuting. At the same time, the edge focusing unit deflects and converges the low color temperature light of the second LED located at both ends towards the central area of ​​the module, which can change the propagation path of the low color temperature light, avoid the divergence and waste of edge light, and make the low color temperature compensation light accurately superimposed on the effective lighting area of ​​the main light pattern. Furthermore, by superimposing and coordinating low color temperature compensation light patterns with high color temperature main light patterns within a predetermined illumination area, the spectral structure of the main light pattern can be optimized and compensated, balancing the color temperature and spectral band ratio of the light within the illumination area. This significantly improves the overall light penetration, effectively suppressing phenomena such as specular reflection, road surface whitening, and glare caused by water film on rainy roads. Simultaneously, it reduces the scattering effect of water mist and dust on light in foggy and dusty weather, shortens the beam divergence range, and improves the effective illumination distance and visual clarity of the headlights. This avoids problems such as blurred road details and misjudgment of road conditions, significantly improving driving safety in adverse weather conditions. Moreover, the driving control unit can independently control the luminous states of the first and second LEDs, allowing for flexible switching of the light source operating mode according to different driving conditions and weather environments.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0030] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0031] With the rapid iteration of automotive intelligence and electrification technologies, in-vehicle lighting systems, as a core component of vehicle active safety, have also undergone comprehensive technological upgrades and innovations. Compared to traditional halogen headlights and xenon headlights, LED headlights, with their multiple advantages such as high luminous efficiency, low energy consumption, long lifespan, fast start-up speed, compact size, and strong styling flexibility, are gradually replacing traditional lighting configurations. They are now widely used in various passenger vehicles, including family sedans and SUVs, becoming the mainstream in-vehicle lighting solution in the current automotive market and a core lighting configuration that automakers are standardizing and emphasizing in high-end vehicles.

[0032] Driven by industry technological upgrades, the color temperature of LED headlights in mainstream mass-produced vehicles has generally increased to around 6000K, with a light color close to natural white light. This completely eliminates the drawbacks of traditional headlights, such as yellowish tint, insufficient brightness, and blurred vision. In typical driving scenarios such as dry asphalt roads and straight roads at night, high color temperature LED headlights provide uniform illumination, sufficient road surface illumination, and high image clarity, creating a clear and wide driving field of vision for the driver. This effectively covers the road ahead and the road conditions on both sides, fully meeting the basic lighting needs of users for daily urban commuting, short-distance travel, and regular nighttime driving, significantly improving driving comfort and basic safety under normal road conditions.

[0033] However, high color temperature 6000K LED headlights have an inherent spectral structure defect. Their emission spectrum is concentrated in the short-wavelength blue light band, with a high peak intensity of blue light, while the proportion of yellow and red light bands, which are more comfortable for the human eye and have stronger penetrating power, is significantly low. This spectral characteristic leads to a significant decrease in lighting performance under adverse weather conditions, resulting in a clear limitation in their use. During rainy driving, a uniform film of water accumulates on the road surface, creating a specular reflection effect. The short-wavelength blue light in high color temperature LED headlights is extremely sensitive to water reflection and is easily reflected in large quantities by the water film on the road surface, resulting in adverse optical phenomena such as large-area whitening of the road surface, localized strong glare, dynamic watermarks causing blinding effects, and continuous road glare. These problems directly obscure details of road conditions such as markings, potholes, and water accumulation areas, making it impossible for drivers to accurately identify road conditions, seriously interfering with drivers' judgment of road conditions and driving operations, and creating potential driving safety hazards.

[0034] Furthermore, in low-visibility weather conditions such as rain, fog, sandstorms, and dust storms, the large number of suspended water droplets and dust particles in the air strongly scatter and refract the short-wave blue light from LED headlights. This causes the originally focused lighting beam to diverge rapidly, resulting in severe glare and a significant decrease in beam focus and penetration. This problem directly leads to a substantial reduction in the effective illumination distance and the narrowing of the illumination coverage area. The driver's effective field of vision is drastically reduced, and the clarity and layering of road vision are severely diminished. This makes it impossible to anticipate road conditions, obstacles, and the dynamics of pedestrians and vehicles ahead, greatly weakening the lighting safety performance of the headlights and significantly increasing the risk of traffic accidents in adverse weather conditions. It fails to meet the safe driving lighting requirements under complex and harsh conditions.

[0035] Based on this, the embodiments of this application provide a variable color temperature automotive lighting module and vehicle, enabling the vehicle lights to achieve variable color temperature lighting function, allowing the vehicle lights to adapt to various driving environments, and significantly improving driving safety.

[0036] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0037] This application provides a variable color temperature automotive lighting module, such as... Figures 1-15 As shown, the system includes an LED light source array 1, a light distribution component 2 corresponding to the LED light source array 1, and a drive control unit 3. The LED light source array 1 includes multiple first LEDs 11 disposed in the middle of the LED light source array 1 and second LEDs 12 disposed at both ends of the multiple first LEDs 11, the emission color temperature of the second LEDs 12 being lower than that of the first LEDs 11. The light distribution component 2 includes multiple central focusing units 25 corresponding to the multiple first LEDs 11 and edge focusing units 26 corresponding to the second LEDs 12 located at both ends. The multiple central focusing units 25 are configured to project the light emitted by the first LEDs 11 into a main light pattern covering a predetermined lighting area, and the edge focusing units 26 are configured to deflect the light emitted by the second LEDs 12 towards the central region where the central focusing units 25 are located, so as to jointly form a color temperature compensation light pattern superimposed with the main light pattern within the predetermined lighting area. The drive control unit 3 is used to control the emission state of the first LEDs 11 and the second LEDs 12 respectively.

[0038] Therefore, by setting the LED light source array 1 into a partitioned structure with multiple first LEDs 11 arranged in the middle and second LEDs 12 arranged at both ends, and limiting the color temperature of the second LEDs 12 to be lower than that of the first LEDs 11, the light source array can simultaneously possess a high color temperature main light source and a low color temperature compensation light source. Compared with a single 6000K high color temperature LED light source, it can effectively make up for the spectral defects of insufficient proportion of yellow and red light bands in high color temperature light sources. The low color temperature second LEDs 12 can supplement the yellow and red light bands, weaken the short-wave blue light peak of the overall light source, and reduce the sensitivity of light to reflection and scattering of water and suspended particles from the source of the light source. It can retain the advantages of the high color temperature white light of the first LEDs 11, which is transparent and clear in imaging, and ensure the lighting vision of conventional dry roads. It can also improve the problem of easy reflection and scattering of blue light in bad weather.

[0039] By setting a central focusing unit 25 corresponding to the first LED 11 and an edge focusing unit 26 corresponding to the second LED 12, the central focusing unit 25 can focus and project the high color temperature light of the first LED 11 to form a main light pattern covering the predetermined lighting area of ​​the vehicle. This can stably maintain sufficient road illuminance and clear road imaging effect under normal road conditions, meeting the lighting needs of daily commuting. At the same time, the edge focusing unit 26 deflects and converges the low color temperature light of the second LED 12 located at both ends towards the central area of ​​the module, which can change the propagation path of the low color temperature light, avoid the dispersion and waste of edge light, and make the low color temperature compensation light accurately superimposed on the effective lighting area of ​​the main light pattern. Furthermore, by superimposing and coordinating low color temperature compensation light patterns with high color temperature main light patterns within a predetermined lighting area, the spectral structure of the main light pattern can be optimized and compensated, balancing the color temperature and spectral band ratio of the light within the lighting area. This significantly improves the overall light penetration, effectively suppressing phenomena such as specular reflection, road surface whitening, and glare caused by water film on the road surface in rainy weather. At the same time, it reduces the scattering effect of water mist and dust on light in foggy and dusty weather, shortens the beam divergence range, improves the effective illumination distance and visual clarity of the headlights, avoids problems such as blurred road details and misjudgment of road conditions, and significantly improves driving safety in adverse weather conditions.

[0040] The drive control unit 3 independently controls the luminous states of the first LED 11 and the second LED 12, allowing for flexible switching of the light source's operating mode according to different road conditions and weather environments. For example, the first LED 11 can be turned on alone to provide high-color-temperature white light for high-definition illumination under normal road conditions, or the first LED 11 and the second LED 12 can be turned on in conjunction to provide mixed high and low color-temperature light illumination, adapting to harsh conditions such as rain, fog, and dust. Furthermore, the luminous power and on / off state of the second LED 12 can be adjusted independently to precisely regulate the color temperature compensation, achieving dynamic adaptation of the lighting effect and improving the module's environmental adaptability and practicality.

[0041] It is understandable that the LED light source array 1 can be an integrated light source component composed of multiple LED beads of different color temperatures arranged in a preset positional pattern. It is the core light-emitting component of this module. For example, the LED light source array 1 can adopt a partitioned arrangement structure with high color temperature beads in the middle and low color temperature beads at both ends, so as to output lighting light with different spectral characteristics.

[0042] The light distribution component 2 is an optical shaping component set on the light-emitting side of the LED light source array 1. It can be used to focus, refract, deflect and shape the light emitted by the LED light source, and regulate the light propagation path.

[0043] The main light type refers to the basic lighting spot formed by the first LED 11 after being shaped by the central focusing unit 25 in the predetermined lighting area in front of the vehicle. It is the core lighting area for vehicle driving and has the characteristics of uniform illumination, sufficient brightness and fixed coverage.

[0044] Color temperature compensation light pattern refers to the auxiliary lighting spot superimposed on the main light pattern area after the second LED12 is deflected and focused by the edge focusing unit 26. By superimposing low color temperature light, it compensates for the spectral defects of the main light pattern and can optimize the overall lighting color temperature and light transmittance.

[0045] The number of first LEDs 11 can be two, three, four or more, and there is no limitation thereto. The number of second LEDs 12 can also be two, three or more, and there is no limitation thereto. For example, the number of first LEDs 11 can be 7 and the number of second LEDs 12 can be 2; alternatively, the number of first LEDs 11 can be 3 and the number of second LEDs 12 can be 2.

[0046] In addition, such as Figure 1 As shown, the drive control unit 3 may include a circuit board 31, and the LED light source array 1 may be disposed on the circuit board 31, which facilitates the assembly of multiple first LEDs 11 and second LEDs 12.

[0047] Optionally, the emission color temperature of the first LED 11 is c1, 5500K≤c1≤6500K, and the emission color temperature of the second LED 12 is c2, 2700K≤c2≤3300K. Multiple central focusing units 25 are configured to focus and shape the emitted light from their respective first LEDs 11, and edge focusing units 26 are configured to focus and shape the emitted light from their respective second LEDs 12.

[0048] In this way, on the one hand, the first LED11 can stably output high color temperature white light close to the natural light at noon, ensuring the basic advantages of high brightness, good color reproduction, and clear vision in dry road lighting. At the same time, the second LED12 can output warm light with a high proportion of yellow and red light and reduce the proportion of short-wave blue light, accurately adapting the color temperature parameters to the needs of anti-reflection and strong penetration in harsh weather. On the other hand, through the dedicated light-focusing and shaping unit structure, high and low color temperature light can be independently optically corrected, avoiding the problems of scattered light spots, uneven color temperature, and blurred edges after high and low color temperature light are mixed. This ensures that the illumination is uniform and the boundary is regular after the main light pattern and the compensation light pattern are superimposed, further improving the lighting stability under different working conditions.

[0049] The color temperature of the first LED 11 can be 5500K, 6500K, or any value between 5500K and 6500K, without limitation. The color temperature of the second LED 12 can be 2700K, 3300K, or any value between 2700K and 3300K, without limitation.

[0050] Understandably, the aforementioned central focusing unit 25 and edge focusing unit 26 can refract and scatter the emitted light from the corresponding LEDs to achieve focusing and shaping of the emitted light.

[0051] In some embodiments, the LED light source array 1 is along a first direction (e.g. Figure 1 The components are arranged in the direction shown in the middle (x), with the first direction being the left and right direction of the vehicle when the variable color temperature automotive lighting module 10 is installed in the vehicle.

[0052] In this way, by arranging the LED light source array 1 along a first direction parallel to the left and right direction of the vehicle, the overall light source emitting direction can be matched with the lateral paving requirements of the vehicle's conventional forward lighting. This allows the lighting output by the module to cover a wider width of the road surface laterally, adapting to the lateral vision requirements of the vehicle while driving on the road. It avoids the problems of narrow lateral illumination range and large blind spots on both sides caused by the vertical arrangement of the light source, effectively improving the overall road paving width and driving vision coverage of the vehicle.

[0053] Optionally, such as Figure 2 and Figure 9 As shown, a plurality of first LEDs 11 have opposite first ends and second ends along a first direction. At least one second LED 12 is respectively provided on the outer side of the first end and the outer side of the second end. The second LEDs 12 are symmetrically arranged about the center plane that passes through the midpoint of the arrangement of the plurality of first LEDs 11 and is perpendicular to the first direction.

[0054] Therefore, by setting at least one second LED12 on the outer side of the first and second ends of multiple first LEDs11, and symmetrically arranging the second LEDs12 relative to the center of the module, the low color temperature compensation light source is evenly distributed on both sides of the main light source. This allows for synchronous and symmetrical color temperature compensation on both sides of the main light pattern, avoiding the problems of inconsistent road surface color temperature and uneven lighting caused by single-sided compensation. As a result, the spectral distribution of the front lighting area of ​​the entire vehicle is uniform, and the penetration effect is consistent throughout the entire area, improving the balance and comfort of road vision in rainy, foggy, and other weather conditions.

[0055] In some embodiments, such as Figures 2-8 As shown, both the first LED 11 and the second LED 12 are used to form the low beam illumination beam, multiple central focusing units 25 are used to form the main low beam pattern, and edge focusing units 26 are used to form a low beam color temperature compensation pattern superimposed on the main low beam pattern; and / or, as Figures 9-15 As shown, the first LED11 and the second LED12 are both used to form the high beam illumination beam, multiple central focusing units 25 are used to form the main high beam pattern, and the edge focusing units 26 are used to form the high beam color temperature compensation pattern superimposed on the main high beam pattern.

[0056] This allows the lighting module to have the functions of low beam lighting, high beam lighting, or both low beam and high beam lighting. Whether it is short-distance road lighting or long-distance range lighting, it can achieve superposition compensation of high and low color temperature light, so that both high and low beam scenarios have high anti-reflection and strong penetration lighting effects, which greatly improves the lighting performance of vehicles day and night and in all weather conditions.

[0057] In some other embodiments, the light distribution assembly 2 includes a bracket 21, a first optical element 22 and a light shield 23. The first optical element 22 and the light shield 23 are respectively disposed on the bracket 21, and the light shield 23 is located between the LED light source array 1 and the first optical element 22.

[0058] Thus, by defining the light distribution component 2 as including the bracket 21, the first optical element 22, and the light shield 23, with the light shield 23 arranged between the LED light source array 1 and the first optical element 22, the bracket 21 can be used to perform relatively precise positioning and assembly of each optical structure, which is beneficial to improving assembly accuracy and structural stability. At the same time, the light shield 23 can block stray light from the light source, effectively eliminating stray light, spill light, and diffuse reflection light generated by direct light source, and preventing stray light from entering the main light path and causing problems such as whitening of light spots and increased glare, further purifying the lighting pattern and improving the regularity of the main light pattern and the compensation light pattern.

[0059] The first optical element 22 can be snapped onto the bracket 21, or it can be glued to the bracket 21, or it can be set on the bracket 21 in other ways, and there is no limitation on this.

[0060] In addition, the light-shielding plate 23 can be fixed to the bracket 21 to improve the stability of stray light blocking; or it can be movably set on the bracket 21 so that the position of the light-shielding plate can be adjusted according to the situation to flexibly block stray light from different directions.

[0061] Optionally, the light distribution assembly 2 also includes a second optical element 24, which is located between the light source and the light shield 23. In this way, the light emitted from the light source can first undergo primary focusing, correction, and homogenization processing through the second optical element 24, then pass through the light shield 23 to filter out stray light, and finally be precisely shaped by the first optical element 22 to form a multi-level optical light distribution structure. This effectively improves light utilization, reduces light loss from the light source, and further optimizes the light incident angle, improving the accuracy and uniformity of subsequent light pattern superposition.

[0062] The second optical element 24 can be connected to the bracket 21 or the circuit board 31, and there is no limitation on which one is connected.

[0063] The central focusing unit 25 and the edge focusing unit 26 can be integrally formed on the second optical element 24, thereby allowing the central focusing unit 25 and the edge focusing unit 26 to be assembled to their respective positions simultaneously, reducing assembly difficulty. For example, when the second optical element 24 includes a condenser, the central focusing unit 25 and the edge focusing unit 26 can be composed of a condenser.

[0064] The first optical element 22 may include a lens; the second optical element 24 may include at least one of a condenser, a silicone needle, a small reflector, and a silicone head.

[0065] Therefore, optical components can be flexibly combined according to the module assembly space and optical parameter requirements. It can achieve high-precision long-distance light focusing and light pattern shaping through lenses to ensure lighting range and paving effect. It can also achieve small-angle precise light focusing and uniform light correction through diverse secondary optical structures, adapting to the assembly size and optical design requirements of headlights of different models, and improving the versatility of module structure and the flexibility of optical design.

[0066] In other embodiments, the first optical element 22 may also include a reflector cup, which can reflect, gather, and shape light rays by having a high-precision curved surface on the inner wall of the reflector cup; or the first optical element 22 may include an integrated optical guide plate, etc., which is not limited.

[0067] In other embodiments, such as Figure 1 As shown, the drive control unit 3 may include a circuit board 31, an LED light source array 1 is disposed on the circuit board 31, and the variable color temperature automotive lighting module 10 may also include a heat sink 4, which is disposed on the side of the circuit board 31 away from the LED light source array 1.

[0068] Therefore, the heat generated during the operation of the LED light source can be quickly conducted and dissipated through the heat sink 4, which can effectively reduce the operating temperature of the LED beads, circuit board 31 and driving circuit, avoid color temperature drift, brightness decay and aging failure of the light source caused by overheating under high brightness and long-term operation, help stabilize the light emission accuracy of the high and low color temperature light sources of the module, and at the same time greatly improve the working stability and service life of the module.

[0069] The heat sink 4 can be implemented in various ways. For example, the heat sink 4 can include a finned heat sink 4, or the heat sink 4 can include a heat sink plate with a cooling cavity, which can be filled with coolant. Of course, in other embodiments, the heat sink 4 can also be implemented in other ways, as long as it can dissipate heat from the LED light source array 1, and there is no limitation on this.

[0070] The aforementioned drive control unit 3 may have a first lighting mode and a second lighting mode; in the first lighting mode, the drive control unit 3 controls the first LED 11 to emit light to form a main light pattern; in the second lighting mode, the drive control unit 3 controls the first LED 11 and the second LED 12 to emit light, and adjusts the light output ratio of the first LED 11 and the second LED 12 to adjust the color temperature after the main light pattern and the color temperature compensation light pattern are superimposed.

[0071] Therefore, by having a first lighting mode and a second lighting mode, the drive control unit 3 can independently control the first LED 11 to emit light to form a standard main light pattern, while the second mode can synchronously control the emission of dual light sources and adjust the light output ratio to dynamically superimpose the color temperature. This allows the lighting effect of the variable color temperature automotive lighting module 10 to be adjusted more intelligently. In normal sunny weather, the first mode can ensure a high-definition and bright white light lighting effect, while in severe weather, the second mode can dynamically adjust the high and low color temperature light ratio to accurately control the overall lighting color temperature and spectral ratio. It can also adaptively adjust the penetration performance according to the concentration of rain and fog and the level of visibility, thus taking into account both the normal high-definition lighting and the dual requirements of anti-glare and anti-scattering light in severe working conditions. This improves the intelligence level and scene adaptability of the variable color temperature automotive lighting module 10.

[0072] The drive control unit 3 can control the illumination and deactivation of the first LED 11 and the second LED 12 by opening and closing the switch; it can also adjust the light output ratio of the first LED 11 and the second LED 12 by controlling the magnitude of the current flowing through the first LED 11 and the second LED 12, thereby achieving stepless control of the color temperature. In other embodiments, the central focusing unit 25 and the edge focusing unit 26 are each composed of at least one of a concentrator, a small reflector, a silicone head, and a silicone needle.

[0073] This greatly enriches the forms of module optical structure implementation. Different focusing structures can be flexibly selected according to product positioning, assembly space, and cost requirements. Under the premise of ensuring the core functions of accurate shaping of the main light pattern and stable superposition of the compensation light pattern, the structural design difficulty and mass production assembly cost of the module can be greatly reduced, making it easier to mass produce products.

[0074] The central focusing unit 25 and the edge focusing unit 26 can both be composed of a focusing device, or they can be composed of different optical structures, and there is no limitation on this.

[0075] like Figures 16-19 As shown, in some embodiments, the light distribution component 2 extends along the arrangement direction of the LED light source array 1 and has a light source side surface 2a facing the LED light source array 1 and a light emission side surface 2b facing away from the LED light source array 1. The light source side surface 2a and the light emission side surface 2b can both be curved surfaces, or they can both be complex surfaces including curved surfaces, spherical surfaces, and planes. Of course, the light source side surface 2a and the light emission side surface 2b can also be other types of surfaces, and this is not limited.

[0076] The light-emitting side surface 2b may include a central light-emitting surface segment 221 located in the middle of the light distribution assembly 2 and multiple side light-emitting surface segments 222 located on both sides of the central light-emitting surface segment 221. The central light-emitting surface segment 221 protrudes relative to the side light-emitting surface segments 222 in a direction away from the LED light source array 1. The multiple side light-emitting surface segments 222 gradually approach the LED light source array 1 from the middle of the light distribution assembly 2 towards both ends, so that the light-emitting side surface 2b forms a segmented stepped curved surface that protrudes in the middle and gradually decreases on both sides.

[0077] Therefore, by extending the light distribution component 2 along the direction of the light source arrangement, and by adopting a segmented stepped curved surface structure with a central protrusion and gradually decreasing sides, the central part of the light distribution component 2 corresponding to the main light source area has a longer optical path, which can meet the needs of long-distance focusing and long-distance illumination of high color temperature main light type, so that the range of the main lighting area in front of the vehicle is sufficient; the side surfaces that gradually decrease on both sides can adapt to the deflection light distribution needs of low color temperature light sources at the edge, guide the compensation light to converge and superimpose inward, and avoid the light from both sides to spill out and diverge. While improving the main lighting range, it also improves the global color temperature compensation effect, which can both improve the lighting range and optimize the spectral effect.

[0078] In addition, the light source side surface 2a may include a plurality of focusing surface units 211 arranged sequentially along the arrangement direction of the LED light source array 1; each focusing surface unit 211 protrudes toward the corresponding first LED 11 or second LED 12, and adjacent two focusing surface units 211 are connected by a transition surface 212 that is recessed away from the LED light source array 1, so that the light source side surface 2a forms a continuous concave-convex profile.

[0079] This allows each LED light source to have an independent focusing and light distribution zone, enabling more precise collection and shaping of light from individual LEDs. This avoids crosstalk and interference between adjacent LEDs, effectively reducing light loss and improving light utilization, thus resulting in better lighting effects for the lighting module.

[0080] In addition, such as Figure 18 and Figure 19 As shown, each light-concentrating surface unit 211 includes a light-incident end face 2111 facing the corresponding LED and two lateral light-distributing surfaces 2112 extending from both sides of the light-incident end face 2111 in a direction away from the corresponding LED; in the cross section along the arrangement direction of the LED light source array 1, the distance between the two lateral light-distributing surfaces 2112 gradually decreases in the direction away from the corresponding LED.

[0081] Therefore, the distance between the two lateral light distribution surfaces 2112 of the focusing surface unit 211 gradually decreases along the light emission direction, which can gradually gather and focus the large-angle divergent light emitted by the LED, greatly reduce the ineffective scattered light, improve the light focusing efficiency and illumination concentration, and further improve the effective illumination distance of the module and the accuracy of road lighting.

[0082] The light-incident end face 2111 can be a part of a sphere, a convex arc surface, or a plane; there is no limitation on this.

[0083] The lateral light distribution surface 2112 can be curved or flat, and there is no limitation on it.

[0084] Optionally, the focusing surface unit 211 corresponding to the first LED 11 is a central focusing surface unit, and the focusing surface unit 211 corresponding to the second LED 12 is an edge focusing surface unit; the edge focusing surface unit is an asymmetric focusing surface unit, and its inner light distribution surface near the middle of the light distribution component 2 and its outer light distribution surface away from the middle of the light distribution component 2 have different cross-sectional profiles, so that the main light emission direction of the edge focusing surface unit is deflected toward the middle of the light distribution component 2.

[0085] Therefore, the light output effect of the second LED12 at the edge can be improved from the optical structure. This allows the low color temperature compensation light to automatically converge and superimpose on the main lighting area without the need for additional reflective or refractive devices. This effectively avoids the problems of compensation failure and light waste caused by the edge compensation light scattering to the outside of the vehicle. As a result, all low color temperature light can effectively act on the main paved area, thereby further improving the spectral optimization and anti-glare effect of the entire road surface under adverse weather conditions.

[0086] In one application scenario, the aforementioned variable color temperature automotive lighting module 10 has an LED light source array 1 arranged horizontally, with seven first LEDs 11 evenly distributed in the center of the array. The seven first LEDs 11 are arranged at equal intervals along a first direction. The emission color temperature of the first LEDs 11 is set to 5500K-6500K, which is standard natural white light with pure color and high brightness, ensuring high-definition lighting effect on conventional roads. A second LED 12 is symmetrically arranged at each of the left and right ends of the seven first LEDs 11. The emission color temperature of the second LEDs 12 is set to 2700K-3300K, which is warm white light source. Compared with the first LEDs 11, it has a higher proportion of yellow and red light bands and a lower short-wave blue light peak, which has stronger fog and water penetration performance.

[0087] The light distribution component 2 can be a concentrator, which covers the light-emitting side of the LED light source array 1 and is set up one-to-one with the LED light source array 1. Among them, the number of central concentrator units 25 is the same as the number of first LEDs 11, with a total of 7 units. The 7 central concentrator units 25 are installed facing each of the 7 first LEDs 11. Each central concentrator unit 25 adopts a convex lens concentrator structure, which can focus and shape the high color temperature light emitted by the first LEDs 11, and project the light into the standard predetermined lighting area in front of the vehicle in a regular manner, forming a main light pattern with uniform illumination and clear boundaries, effectively covering the road surface in front of the vehicle and on both sides, and meeting the daily night driving lighting needs.

[0088] The number of edge focusing units 26 matches the number of second LEDs 12. One edge focusing unit 26 is set at each of the left and right ends, and the second LEDs 12 at the corresponding ends are installed facing each other. The edge focusing unit 26 adopts an eccentric curved surface focusing structure. Its optical curved surface is tilted towards the center of the module, which can refract and focus the low color temperature warm white light emitted by the second LEDs 12, and accurately deflect the light to the main lighting area corresponding to the central focusing unit 25. This allows the low color temperature light to be completely superimposed on the predetermined lighting area covered by the main light pattern, forming a full-coverage color temperature compensation light pattern with no light deviation and no lighting blind spots.

[0089] Among them, such as Figure 1 As shown, there can be two concentrators, which are arranged along a second direction, which is the vertical direction of the vehicle when the color-changing automotive lighting module is installed. One of the concentrators can be a low beam concentrator 241 to form a low beam, and the other can be a high beam concentrator 242 to form a high beam, so that the lighting module can be compatible with both low beam and high beam lighting functions at the same time.

[0090] The drive control unit 3 can use a dedicated automotive LED driver chip with multiple independent dimming drive channels built-in. These channels are electrically connected to each of the first LED 11 and the second LED 12 individually, enabling independent on / off control and stepless brightness adjustment for the first LED 11 and the second LED 12. Specifically, in normal driving scenarios such as dry roads and sunny weather, the drive control unit 3 only controls the first LED 11 to turn on, outputting high color temperature pure white light to achieve high brightness and high clarity road illumination. In adverse scenarios with low visibility, such as rain, fog, and sandstorms, the drive control unit 3 simultaneously turns on both the first LED 11 and the second LED 12. By superimposing high and low color temperature light, the illumination spectrum is optimized, light penetration is improved, and road reflections and light scattering are suppressed. At the same time, the brightness of the second LED 12 can be dynamically adjusted according to the ambient visibility to precisely adjust the overall illumination color temperature and adapt to the lighting needs of different adverse conditions.

[0091] In addition, such as Figure 20 As shown, the lighting module can be integrated into the automotive headlight assembly in one or more arrays. The variable color temperature automotive lighting module 10 may also include a housing 5. The LED light source array 1, light distribution component 2, and bracket 21 can all be set in the housing 5. The housing 5 can be assembled into the vehicle by means of clips, bolts, etc. It is compatible with the lighting installation structure of most passenger car models, has strong versatility, and low modification and assembly costs.

[0092] This application also provides a vehicle including the variable color temperature automotive lighting module 10 as described in any of the above embodiments.

[0093] This allows vehicles to be equipped with an onboard lighting system that can dynamically adapt to all weather conditions and intelligently switch color temperature modes, effectively avoiding issues such as glare, blurred vision, and poor safety caused by headlights in adverse weather conditions. This significantly improves the lighting safety, comfort, and intelligence of vehicles during all-weather driving, thereby enhancing the overall competitiveness of the vehicle.

[0094] Furthermore, the variable color temperature automotive lighting module 10 in the vehicle is the variable color temperature automotive lighting module 10 described in any of the above embodiments. Therefore, the variable color temperature automotive lighting module 10 can have roughly the same effect as the variable color temperature automotive lighting module 10 described in any of the above embodiments. For details, please refer to the above description, which will not be repeated here.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
