Description

SIMULATED PIVOT LOCATION USING MOTION CONTROLCROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 639,287, filed April 26, 2024, the entire disclosure of which is hereby incorporated by reference.FIELD

[0002] This disclosure relates generally to vehicle lighting systems, and more particularly to vehicle lighting systems capable of passing light through a small aperture in a vehicle.BACKGROUND

[0003] Vehicle lighting systems may serve to enhance aesthetic appearance and functionality of a vehicle. Traditionally, lighting systems associated with the exterior of a vehicle are directly integrated with the vehicle’s bodywork and exterior profile, typically requiring a space claim in the bodywork comparable to the size of the lighting system. As vehicle aesthetics and desired functionality evolve, there exists a need for improved vehicle lighting systems.SUMMARY

[0004] Disclosed herein are implementations of a light system. The light system may include one or more light modules and an actuation system. The light modules may include a light housing with a forward end and a rearward end and a light source connected to the light housing. The light source may be configured to direct light through one or more apertures of a component of a vehicle from a location interior to the component to a location exterior to the component. Thus, the light system may be situated behind a component with the ability to illuminate areas exterior to the component. The actuation system may selectively move the light housing about a virtual pivot point located forward of the forward end of the light housing. The moving of the light housing relative to the one or more apertures directs the light through the virtual pivot point. The virtual pivot point may be located so that substantially all the light extends through the one or more apertures. As such, substantially all the light directed from the light system is used for illuminating areas exterior to the component for various light module positions.

[0005] The virtual pivot point may be proximate to a center of the one or more apertures. The light may extend through the one or more apertures without the component blocking any of the light. The light source may be located a distance away from the component so that the light sourceis not visible from outside the vehicle. The actuation system may comprise a multi-bar linkage and an actuator selectively moving the multi-bar linkage through a range of motion.

[0006] The actuation system may comprise two or more actuators configured to translate and rotate the light housing. The two or more actuators may be configured to translate and rotate the light housing via manipulation of two or more points on the light housing. The two or more points may be spaced with respect to an axis extending between the forward end of the light housing and the rearward end of the light housing. Each actuator of the two or more actuators may comprise an independently adjustable linear actuator. Alternatively, each actuator of the two or more actuators may comprise an independently adjustable actuator (e.g., rotationally adjustable). The independently adjustable actuators (e.g., rotational) may selectively actuate a mechanism. The mechanism may be a belt and pulley, a gear and chain, a rack and pinion, a gear drive, or the like.

[0007] The actuation system may comprise a single actuator selectively actuating a mechanism that translates and rotates the light housing. The actuation system may be configured to translate and rotate the light housing via manipulation of two or more points on the light housing. The two or more points may be spaced with respect to an axis extending between the forward end of the light housing and the rearward end of the light housing. The mechanism may be a belt and pulley, a gear and chain, a rack and pinion, a gear drive, or the like.

[0008] The teachings herein provide a light system where the light system may include one or more light modules and an actuation system. The light modules may include a light housing and a light source. The light housing may include a forward end, one or more forward control mounts, a rearward end, and one or more rearward control mounts. The light source may be connected to the light housing and configured to direct light through one or more apertures of a component of a vehicle from a location interior to the component to a location exterior to the component. Thus, the light system may be situated behind the component with the ability to illuminate areas exterior to the component. The actuation system may selectively move the light housing via engagements with the one or more forward control mounts and the one or more rearward control mounts so that the light from the light source is substantially all directed through the one or more apertures as the light housing is moved by the actuation system. As such, substantially all of the light directed from the light system is used for illuminating areas exterior to the component for various light module positions.

[0009] For the light system the one or more forward control mounts may be located proximate the forward end of the light housing and the one or more rearward control mounts may be located rearward of the one or more forward control mounts. Alternatively, the one or more rearwardcontrol mounts may be located proximate the rearward end of the light housing and the one or more forward control mounts may be located forward of the one or more rearward control mounts. The actuation system may comprise two or more independently adjustable actuators configured to translate and rotate the light housing via movement of the one or more forward control mounts and the one or more rearward control mounts such that the light source is aimed at a virtual pivot point during or following the movement.

[0010] The light system may include one or more light modules and an actuation system. The light modules may be configured to be spaced a distance from one or more apertures that extend through a component of a vehicle. The light modules may include a light housing comprising a forward end and a rearward end and a light source connected to the light housing and configured to direct light through at least one of the one or more apertures from a location interior to the component to a location exterior to the component. Thus, the light system may be situated behind a component with the ability to illuminate areas exterior to the component. The actuation system may selectively move the light housing through a range of motion so that the light from the light source is substantially all directed through the one or more apertures as the light housing moves throughout the range of motion. As such, substantially all of the light directed from the light system is used for illuminating areas exterior to the component for various light module positions.

[0011] In certain implementations of the light system the distance may be in a range (e.g. from about 20 mm to about 300 mm or about 40 mm to about 200 mm). Additionally, the range of motion may include a first position of the light housing at an angle relative to an intermediate plane (e.g. about 10 degrees upward) and a second position of the light housing at an angle relative to the intermediate plane (e.g. about 60 degrees downward).BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Referring to FIG. 1 , a system 100 is illustrated. The system 100 may include a vehicle 102 equipped with a light system 104. The light system 104 may provide light 106 through an aperture 108 in a vehicle component 110. Light 106 may be provided around the vehicle 102 in a plurality of directions 112, offering flexibility for various lighting conditions and requirements. Although illustrated as being located at a front end 114 of the vehicle 102, the light system 104 may alternatively be positioned at other locations around the vehicle 102 depending on the application. The system 100 further includes a controller 116, operatively connected to the light system 104, which may facilitate adjustment of the light 106 in terms of direction, intensity, and / or pattern, thereby enabling customization based on user inputs or environmental conditions.

[0030] The vehicle 102 may be a motor vehicle such as a sedan, coupe, convertible, SUV, XUV, hatchback, wagon, pickup truck, minivan, full-size van, motorcycle, bus, or light commercial vehicle (e.g., a delivery truck); a heavy commercial vehicle (e.g., a semi-truck); an emergency vehicle (e.g., a police car or ambulance); or specialized equipment such as construction, mining, or farm machinery; or any combination thereof. The light system 104 may serve multiple functions in the vehicle 102. For example, the light system 104 may be used to provide light 106 to enhance safety, visibility, operational efficiency, aesthetics, and ensure compliance with visibility and beam pattern regulations. In certain implementations, the light system 104 may serve as a traditional headlight located at the front end 114 of the vehicle 102 providing light 106 for primary forward illumination offering both high beam and low beam options to accommodate varying road and traffic conditions, thereby ensuring clear visibility for a driver while minimizing glare for other road users. Alternatively, the light system 104 may be located in the front end 114 of the vehicle 102 and serve as daytime running lights, fog lights, or supplemental forward illumination to provide light 106 to improve visibility and safety in low-light or adverse environmental conditions. In selected implementations, the light system 104 may be integrated into the roof of the vehicle 102, a component proximate the roof of the vehicle 102, or other remote locations for specialized applications, including off-road navigation, construction or mining site operations, or emergency response, where elevated lighting positions provide broader and more focused illumination.

[0031] The vehicle component 110 may include, be, or form part of a cover, front or rear fascia, grill, bumper, side mirror, hood, fender, roof mounted bar, or remote mounted component (e.g., a fender mounted housing). The aperture 108 in the vehicle component 110 through which the light 106 is provided may comprise a variety of shapes and sizes; it may comprise a cover (e.g. lens, screen, grill, transparent shield, or the like) or be open; it may be concealed by, or be a part of, other vehicle 102 features (e.g. vents or grill openings); and it may be oriented in a variety of ways (e.g. straight, curved, or angled).

[0032] The light system 104 may be integrated into the vehicle 102 to provide optimal functionality and aesthetics. For example, the light system 104 may be recessed a length behind the vehicle component 110 and an aperture 108 size smaller than the light system 104 may be selected to shroud the light system 104 by the vehicle component 110. Functionally, shrouding the light system 104 by the vehicle component 110 may serve to shield the light system 104 from exposure to debris, impacts, or weather elements; to minimize protrusion of the light system 104 into the body of the vehicle 102 to benefit aerodynamics; and / or to provide ventilation channels to aid in dissipation of heat generated by the light system 104 or other heat sources corresponding to the vehicle 102. Aesthetically, shrouding the light system 104 may provide more seamlessintegration of the light system 104 into the bodywork of the vehicle 102. Shrouding the light system 104 may also enhance manufacturer brand identity of the vehicle 102.

[0033] The light system 104 may provide light 106 using one or more sources such as halogen, high intensity discharge (HID), light-emitting diode (LED), or laser based on requirements and the intended application of the vehicle 102. For example, the light system 104 may utilize halogen sources in applications where a cost-effective and reliable solution is preferred, while HID, LED, and laser sources may be employed for higher performance applications, offering superior brightness, efficiency, and range. Each source of light 106 may contribute unique advantages to meet a variety of functional and aesthetic requirements. The light system 104 may integrate projector, reflector, matrix, high definition, and adaptive lighting technologies to tailor the shape, intensity, and direction of the light 106 to the specific needs of the driver and the driving environment. Additionally, the light system 104 may incorporate auxiliary features such as cornering lights to enhance visibility when navigating turns; daytime running lights (DRLs) to improve visibility of the vehicle 102 during daylight hours; and turn signals to communicate directional intent to other road users, and side markers or reflex reflectors that assist in adding conspicuity to a vehicle. These features collectively enable the light system 104 to address a wide range of lighting conditions and operational requirements.

[0034] The controller 116 may be an electronic component, operatively connected to the light system 104, with ability to manage activation, shape, intensity, and direction of the light 106 emitted from the light system 104. The controller 116 may process driver inputs, such as mode selection (e.g. high-beam, low-beam, daytime running lights, fog lights), as well as data from sensors of the vehicle 102 including ambient light levels, steering angle, suspension position, and speed. In response to inputs and data, the controller 116 may adjust the operation of the light system 104 to optimize visibility, enhance safety, and adapt to varying driving conditions. For example, where the light system 104 comprises a headlight, the controller 116 may automatically switch between low and high beams, adjust the angle of the light 106 emitted based on suspension displacement because of vehicle 102 payload or road irregularities, or adjust beam patterns in response to road curvature. Furthermore, the controller 116 may incorporate compatibility with vehicle 102 automation and connectivity features. For instance, the controller 116 may communicate with external sensors or cameras to adjust patterns of light 106 based on detected vehicles, obstacles, pedestrians, or changes in road conditions. Additionally, the controller 116 may support programmable lighting modes, allowing users to customize light intensity, direction, or color for specific scenarios, such as off-road, worksite tasks, and urban or rural commuting.

[0035] By offering this level of flexibility, integration, and adaptability, the light system 104 ensures a comprehensive solution that addresses both current and future requirements for realtime customization, improving safety and performance across diverse environments.

[0036] Referring to FIG. 2, the light system 104 may include a light module 200 for providing light 106 through the aperture 108 in the vehicle component 110. The light module 200 may be situated at a location 202 within an interior 204 of the vehicle component 110. The location 202 may be spaced a distance 206 from the vehicle component 110. The light module 200 may be positioned to direct the light 106 through the aperture 108 to a location exterior 208 to the vehicle component 110. An actuation system 210 may selectively change the light module position 212 via translation and rotation, thereby aiming (e.g. directing) the light module 200 and the light 106 emitted therefrom. The light module 200 may selectively move through a range of motion. The range of motion may be defined in terms of a first position 212a, a second position 212b, a third position 212c, and a variety of positions there within, which may correspond to various lighting requirements of the vehicle 102. The range of motion may be about 20 mm or more, 50 mm or more, 75 mm or more, 100 mm or more, or about 125 mm or more. The range or motion may be about 300 mm or less, about 275 mm or less, about 250 mm or less, about 225 mm or less, about 200 mm or less, or about 175 mm or less. Based on the movement of the actuation system 210, the actuation system 210 may determine what areas or locations exterior 208 to the vehicle component 110 are illuminated by light 106 emitted from the light module 200.

[0037] The light system 104 may include or define a virtual pivot point 214. The actuation system 210 may selectively move the light module 200 in a manner such that the light 106 emitted from the light module 200 may pivot about the virtual pivot point 214. That is, the virtual pivot point 214 point may be a theoretical location, for example, located forward 216 of the light module 200, around which the light module 200 moves based on the light 106 emitted therefrom passing through the virtual pivot point 214. The virtual pivot point 214 may be fixed in location or may move within a region 218 wherein the size of the region 218 is limited such that desired lighting requirements of the vehicle 102 may be met while permitting flexibility for manufacturing tolerances of components of the light system 104 and control variability of the actuation system 210.

[0038] The virtual pivot point 214 may be located in the region 218 proximate an aperture center 220 in the vehicle component 110. The region 218 may be located such that during movement (e.g. moving from the first position 212a to the second position 212b, moving from the second position 212b to the third position 212c, or the like) of the light module 200, and based on the shape of the aperture 108 and thickness of the vehicle component 110, substantially all light106 is directed through the aperture 108. Alternatively, the region 218 of the virtual pivot point 214 may be located such that all of the light 106 extends through the aperture 108 without the vehicle component 110 blocking any of the light 106. The region 218 of the virtual pivot point 214 may also be located such that the vehicle component 110 acts as a shutter blocking a portion of light 106 to prevent illumination of undesirable areas exterior of the vehicle component 110. In instances where the aperture 108 may involve a cover (e.g. a lens, screen, protective element), the region 218 of the virtual pivot point 214 may be located to account for refraction of light 106 through the cover based on requirements for light 106 emitted exterior to the vehicle component 110. The virtual pivot point 214 may be located on a plane 221 that is coplanar with the vehicle component 110.

[0039] The light module 200 may serve as an integral component of the light system 104 of the vehicle 102 and may offer precise and adaptable illumination for a range of driving conditions. The light module 200 may comprise a light housing 222 and a light source 224 engineered to function together. In certain implementations, the light module 200 may incorporate advanced interfacing and mounting mechanisms to ensure structural integrity, functionality, and integration with the actuation system 210 and other subsystems of the vehicle 102.

[0040] The light housing 222 may serve as a structural framework for the light source 224 of the light module 200. This may ensure secure positioning of the light module 200 and protection of the light module 200 from external environmental factors. To achieve this, the light housing 222 may feature dedicated mounting sockets, retention brackets, clamps, thermal pads, and alignment features for the light source 224. The light housing 222 may comprise a forward end 226 and a rearward end 228 and may interface with other components of the light system 104 including the actuation system 210. In some implementations, the light housing 222 may contain mounting points or brackets. For example, the light housing 222 may contain a forward control point 230 located in relation to (e.g. proximate) the forward end 226 of the light housing 222 and a rearward control point 232 located in relation to (e.g. proximate) the rearward end 228 of the light housing 222. The forward control point 230 and the rearward control point 232 may be spaced with respect to an axis 234 extending between the forward end 226 of the light housing 222 and the rearward end 228 of the light housing 222. The forward control point 230 and the rearward control point 232 may be used to interface with the actuation system 210 and may include direct couplings such as ball-and-socket joints, hinged connections, pivot mounts, or the like to allow rotational movement enabling smooth adjustment of the light module position 212. Additionally, the forward control point 230 and the rearward control point 232 may includevibration-dampening materials, such as rubber or polyurethane bushings, to reduce the impact of road vibrations and enhance durability of the light module 200.

[0041] The light housing 222 may be constructed from materials commonly used in motor vehicle applications, such as metals, composites, durable polymers, or the like selected based on requirements for cost, weight, strength, and thermal management. Beyond the materials used, the light housing 222 may integrate features such as heat dissipating elements (e.g. fins), heat sinks, and thermally conducting surfaces in contact with the light source 224 to manage the thermal output of high-intensity sources of light 106. To further enhance its functionality, the light housing 222 may also include a lens or a shutter to assist in shaping or modulating the light 106 emitted from the light source 224 for specific requirements of the vehicle 102. Moreover, the light housing 222 may incorporate sensor provisions, allowing for the integration of useful components like position sensors, ambient light sensors, or temperature sensors, which may provide feedback to the controller 116. Provisions for electrical routing and connections to the light source 224 or other sensors may be integrated into the light housing 222. Additionally, the light housing 222 may include features such as quick release mechanisms to improve serviceability as well as provisions for gaskets and seals at interfaces to assist in environmental protection.

[0042] The light source 224 may be mounted securely to the light housing 222 and may be capable of emitting light using a variety of technologies such as halogen, LED, HID, and laser depending on requirements of the vehicle 102. The light source 224, may be hidden from visibility when viewed from outside the vehicle 102 by choosing the distance 206 of the location 202 of the light module 200 from the vehicle component 110 such that the light source 224 is shrouded by the vehicle component 110. For secure attachment to the light housing 222 and thermal efficiency, the light source 224 may feature dedicated mounting sockets, retention brackets, clamps, and thermal pads for interfacing. These features ensure stability under varying road conditions and optimal heat dissipation for high-performance sources of light 106. The light source 224 may be designed to emit light 106 of varying intensities and colors, offering adaptability for different driving scenarios. Specialized beam shaping technologies, such as lenses or reflectors may be integrated with the light source 224 and may be used to enhance focus, uniformity, and pattern of the light 106. For example, light 106 of the high-intensity white type may be used for standard driving, while amber or yellow hues may be incorporated for signaling or fog-light functions. In addition to its versatility, the light source 224 may include capability for directional lighting within itself allowing it to emit light at adjustable angles to the sides or to focus the beam for forward projection providing additional capability and adjustment. For a light source 224 featuring directional control, motorized pivot mechanisms or electromagnetic actuators may be integratedwith the light source 224 to enable adjustment of the light 106 emitted. Moreover, the light source 224 may also include adaptive driving beam capabilities including selective dimming to reduce glare for oncoming traffic.

[0043] The actuation system 210 may comprise a subsystem of the light system 104, designed to precisely aim the light module 200 to optimize illumination and meet lighting requirements of the vehicle 102. Functionally, the actuation system 210 may provide controlled movement of the light module 200 through a range of motion, enabling adjustments of the light 106 emitted therefrom. The controlled movement of the light module 200 via the actuation system 210 may be defined in terms of light 106 being required to pass through the virtual pivot point 214; by the location 202 of the light module 200 based on the distance 206 of the light module 200 from the vehicle component 110; and in terms of an upward inclination angle 236 and a downward inclination angle 238 of the light 106 relative to an intermediate plane 240 wherein the upward inclination angle 236 may define the first position 212a, the intermediate plane 240 may define the second position 212b, and the downward inclination angle 238 may define third position 212c. Such adjustments may be determined based on vehicle-specific requirements, for example, the upward inclination angle 236 and downward inclination angle 238 may ensure compliance with regulatory standards for vehicle headlights (e.g. low-beam and high-beam). Furthermore, the adjustments may also be used to provide flexibility for adapting to different designs and operating conditions of the vehicle 102. The distance 206 may range from about 60mm to about 160mm; the upward inclination angle 236 may correspond to about 10 degrees, and the downward inclination angle 238 may correspond to about 10 degrees.

[0044] The actuation system 210 may connect to the light module 200 using robust yet flexible mounting configurations, such as ball-and-socket joints, hinged connections, or pivot mounts. These mounting configurations may be used to provide smooth and reliable movement of the light module 200 while maintaining stability during operation. To mitigate the effects of road vibrations and extend the durability of the light system 104, the mounts may incorporate vibrationdampening materials such as rubber or polyurethane bushings. These materials may be used to effectively isolate the light module 200 from external disturbances, maintaining precise alignment and consistent output of light 106.

[0045] The actuation system 210 may interface (e.g. engage) with the forward control point 230 and the rearward control point 232 for manipulating the light module 200. This dual-point configuration may be used to enhance the stability and accuracy of aiming of the light 106 by distributing forces evenly between the actuation system 210 and the light module 200. The actuation system 210 may comprise independently adjustable linear actuators including a firstlinear actuator 242 and a second linear actuator 244 to interface with the forward control point 230 and the rearward control point 232 of the light module 200 respectively to provide precise control and movement tailored to the range of motion of the light module 200. Alternatively, the actuation system 210 may comprise actuation components of various types including electromechanical actuators, stepper motors, servo motors, or the like, to provide precision and control for aiming the light module 200. The actuation system 210 may be used to directly mount components of the light system 104 to the vehicle 102. Alternatively, the actuation system 210 may mount to an intermediate base or housing to secure components of the light system 104 to the vehicle 102. Additionally, the actuation system 210 may comprise mechanisms (e.g. multi-bar linkage, belt and pulley, gear and chain, gear drive, rack and pinion, or the like) used in conjunction with the actuation components to interface with the light module 200.

[0046] The light system 104 may include the controller 116 that is operatively connected to the light module 200 and the actuation system 210 to coordinate and regulate their operation. The controller 116 may be configured to receive input data, process the data, and output control signals to adjust the light 106 emitted from the light module 200 and to adjust light module position 212 via the actuation system 210. The controller 116 may be implemented in various forms, including a dedicated electronic control unit, a programmable logic controller, an embedded microcontroller, or an integrated software module executed within a central processing system of the vehicle 102.

[0047] The controller 116 may incorporate position data to determine the light module position 212. This position data may be obtained through a position sensor 246 operatively connected to the controller 116. The position sensor 246 may provide real-time position feedback, allowing the controller 116 to accurately determine the light module position 212 with respect to the vehicle 102 or road conditions. The position sensor 246 may be separate from the actuation system 210 or it may be integrated with, or into, components of the actuation system 210 to provide corresponding position data directly to the controller 116. The position sensor 246 may include rotary encoders, linear potentiometers, hall effect sensors, optical sensors, gyroscopes, and other suitable position-sensing devices.

[0048] In operation, the controller 116 may process position data from the position sensor 246 and generate precise control signals to coordinate movements of the actuation system 210. This enables accurate and dynamic aiming of the light module 200 in response to various conditions of the vehicle 102 and environmental conditions. The controller 116 may manage one or more actuators within the actuation system 210. When the actuation system 210 contains twoor more actuators, the controller 116 may synchronize their operation to ensure smooth and accurate movement of the light module 200 and the light 106 emitted therefrom.

[0049] The controller 116 may be modularly integrated with the light system 104, enabling it to function as an independent control unit specific to the light system 104. Alternatively, the controller 116 may be physically separate from the light system 104 and connected through wired or wireless communication interfaces. The functionality of the controller 116 may be integrated into an existing control element in the vehicle 102, such as a central vehicle electronic control unit or a body control module, allowing for a shared processing platform. In such configurations, the controller 116 may manage both the light system 104 and other subsystems of the vehicle 102, enhancing efficiency and communication.

[0050] The controller 116 may comprise a modular design enabling flexibility in system architecture and facilitating ease of maintenance or replacement. For example, the controller 116 may be upgraded or reprogrammed to incorporate new features or adapt to changing operational requirements. Additionally, the controller 116 may interface with external systems or sensors of the vehicle 102, such as cameras, radar, or LiDAR systems, to enhance the functionality of the light system 104 and the vehicle 102. For instance, the controller 116 may dynamically adjust the light module position 212 in response to detected objects, road curvature, or environmental conditions.

[0051] Referring to FIG. 3A, FIG. 3B, and FIG. 3C, the actuation system 210 may comprise a multi-bar linkage 300 including a linkage actuator 302 to aim the light module 200 through a range of motion. The range of motion of the light module 200 may be defined by the first position 212a, the second position 212b, the third position 212c, and positions bounded there within, each of which may correspond to specific lighting requirements. The multi-bar linkage 300 may be used to provide a robust and efficient mechanism for achieving precise movement of the light module 200 with a single actuator.

[0052] The multi-bar linkage 300 may include a plurality of bars 304 and a plurality of joints 306, which may vary in shape, size, and material depending on the application and design requirements. The plurality of bars 304 and the plurality of joints 306 may be connected to form a mechanism that allows for controlled, guided motion of the light module 200. The multi-bar linkage 300 may further include a base 308 for mounting the plurality of bars 304, the plurality of joints 306, and the linkage actuator 302. The base 308 itself may take on different configurations. For example, it may comprise a component that provides a rigid platform for the plurality of bars 304 and the plurality of joints 306, or alternatively, it may comprise a bar within the plurality of bars 304.

[0053] The base 308 may also serve as a mounting interface to the chassis or body of the vehicle 102 enabling secure attachment of the actuation system 210 through various means such as fasteners (e.g. rivets, bolts, screws, or studs), brackets, or integrated mounting structures. Additionally, the base 308 may accommodate the attachment of other components related to the vehicle 102 or the light system 104, thereby integrating multiple functions into a compact and efficient assembly.

[0054] The light module 200 may be mounted to the multi-bar linkage 300 at the forward control point 230 and the rearward control point 232 to ensure stability and accurate positioning during actuation. Alternatively, other mounting configurations may be employed to secure the light module 200 to the multi-bar linkage 300, depending on the specific design constraints.

[0055] The linkage actuator 302 used to actuate the multi-bar linkage 300 may comprise a rotational actuator or a linear actuator, depending on the requirements of the light system 104. In implementations where the linkage actuator 302 comprises a rotational actuator, such as a motor, the linkage actuator 302 may drive a bar from the plurality of bars 304 to achieve the desired movement. Alternatively, in implementations where the linkage actuator 302 comprises a linear actuator, the linkage actuator 302 may extend or retract a bar from the plurality of bars 304 to provide controlled displacement, causing the multi-bar linkage 300 to adjust the position of the light module 200 accordingly.

[0056] The multi-bar linkage 300 is able to actuate the light module 200 using a single actuator while delivering smooth and precise movement. This reduces complexity of the actuation system 210 and minimizes the number of expensive components required, resulting in a simple, robust, and easy to control design. Additionally, the multi-bar linkage 300 provides durability and reliability, making it particularly well-suited for vehicle 102 applications where performance under varying conditions is critical.

[0057] Referring to FIG. 4A, FIG. 4B, and FIG. 4C, the multi-bar linkage 300 may comprise a first linkage bar 400 and a second linkage bar 402 that connect the light module 200 to the vehicle 102 or a component of the light system 104. The first linkage bar 400 may be positioned above the light module 200, and the second linkage bar 402 may be positioned below the light module 200. The first linkage bar 400 and the second linkage bar 402 may be connected to the light module 200 via first linkage joints 404 which may comprise pin or ball joints, allowing for rotational freedom. The opposing ends of the first linkage bar 400 and the second linkage bar 402 may be connected to a base, housing, chassis, or directly to a vehicle component or body via second linkage joints 406 which may comprise pin or ball joints with provisions to mount to the vehicle102 (e.g. fasten-on, clip-on, or bonding). The first linkage bar 400 or the second linkage bar 402 may comprise a plate for cradling the linkage actuator 302.

[0058] The linkage actuator 302 is incorporated herein in its entirety to control the movement of the light module 200. The linkage actuator 302, may be a linear actuator connected between the second linkage bar 402 and the light module 200 via a joint of the first linkage joint 404 type. Alternatively, the linkage actuator 302, may be connected between the first linkage bar 400 and the light module 200 via a joint of the first linkage joint 404 type. The first linkage bar 400 is sized in conjunction with the second linkage bar 402 based on kinematics to achieve the desired aim of the light module throughout a range of motion. As the linkage actuator 302 operates by extending or retracting, it induces movement in the first linkage bar 400, the second linkage bar 402, and the light module 200 adjusting the light module position 212 about the virtual pivot point 214. The first linkage bar 400 functions in conjunction with the second linkage bar 402 to guide and stabilize the light module 200 as it moves. This configuration allows the light module 200 to be aimed with precision through the desired range of motion to meet various lighting requirements.

[0059] The use of only two linkage bars and a single actuator reduces the number of components while maintaining smooth and controlled motion of the light module 200. However, two or more linkages may be present (e.g., three or more linkages).

[0060] Referring to FIG. 5, the actuation system 210 may comprise independently adjustable actuators (rotational) including a first rotational actuator 500 and a second rotational actuator 502. These actuators are designed to precisely aim the light module 200 and may engage the light housing 222 at the forward control point 230 and the rearward control point 232. The first rotational actuator 500 may be coupled to the forward control point 230 via a first coupling 504, while the second rotational actuator 502 may be coupled to the rearward control point 232 via a second coupling 506.

[0061] The light module 200 to be aimed in a first direction 508, a second direction 510, as well as intermediate directions there within by adjusting the position of the forward control point 230 and the rearward control point 232. The rotational actuators may include a variety of types such as stepper motors, servo motors, electromagnetic actuators, or the like. The actuators may be mounted to a fixed base or directly to another component of the vehicle 102, depending on the specific application and design constraints.

[0062] Referring to FIG. 6, the actuation system 210 may comprise a first drive component 600 and a second drive component 602 which may comprise rotational actuators. The first drive component 600 may be coupled to a first transmission component 604 and the second drive component 602 may be coupled to a second transmission component 606. The first transmissioncomponent 604 may be coupled to a first driven component 608 and the second transmission component 606 may be coupled to a second driven component 610. The first transmission component 604 and the second transmission component 606 may comprise belts or chains coupled to the drive and driven components via pulleys, chains, or gears. The first driven component 608 and the second driven component 610 may engage the light housing 222 at the forward control point 230 and the rearward control point 232 respectively.

[0063] Referring to FIG. 7, the first transmission component 604 and the second transmission component 606 may comprise racks coupled to the drive and driven components via gears which serve as pinions.

[0064] Referring to FIG. 8, the first transmission component 604 and the second transmission component 606 may comprise idler gears or pulleys coupled to the drive and driven components via gears, chains, or pulleys

[0065] The light module 200 to be aimed in a first direction 508, a second direction 510, as well as intermediate directions by adjusting the position of the forward control point 230 and the rearward control point 232. The drive components and driven components may be connected to a base, a housing, or directly to a vehicle component. This implementation allows flexibility in locating the actuators for packaging and other design requirements of the vehicle 102.

[0066] Referring to FIG. 9, the actuation system 210 may comprise a first drive component 600 which may comprise a first rotational actuator 500. The first drive component 600 may be coupled to a first transmission component 604. The first transmission component 604 may be coupled to a first driven component 608. The first transmission component 604 may comprise idler gears or pulleys coupled to the drive and driven components via gears or pulleys. While the first drive component 600 may comprise a first rotational actuator 500, the first rotational actuator 500 may alternatively be located on the first driven component 608 or the first transmission component 604 wherein these components may then become the first drive component 600. The first drive component 600 and the first driven component 608 may engage the light housing 222 at the forward control point 230 and the rearward control point 232 respectively.

[0067] Referring to FIG. 10, the first transmission component 604 may comprise belts or chains coupled to the drive and driven components via pulleys or gears.

[0068] Referring to FIG. 11 , the first transmission component 604 may comprise a rack coupled to the drive and driven components via gears which serve as pinions.

[0069] The light module 200 to be aimed in a first direction 508, a second direction 510, as well as intermediate directions there within by adjusting the position of the forward control point 230 and rearward control point 232. The drive components, transmission components, and drivencomponents may be connected to a base, housing, or directly to a vehicle component. This implementation allows flexibility in locating the actuators for packaging and design requirements while reducing the number of actuators required for the actuation system 210 to function.

[0070] Referring to FIG. 12, a process 1200 for adjusting the light system 104 is illustrated. The process 1200 may include receiving 1202 a command, validating 1204 the command, determining 1206 actuation to preserve the virtual pivot point 214, executing 1208 actuation differentiating distances in the actuation system 210 to preserve the virtual pivot point 214, validating 1210 position of components of the light system 104, and determining 1212 whether the position of the components of the light system 104 are within tolerance wherein if the position of the components are within tolerance the process 1200 awaits receiving 1202 the next command and if the position of the components are not within tolerance the process 1200 reverts to determining 1206 the actuation to preserve the virtual pivot point 214.

[0071] In receiving 1202 the command, the controller 116 associated with the light system 104 may initiate the process 1200 by receiving 1202 the command. The command may originate from multiple sources, depending on the configuration of the light system 104. For example, a user may manually input the command by interacting with a physical switch or control interface on the vehicle 102. Where the light system 104 comprises a headlight system of the vehicle 102, this may include toggling between low-beam and high-beam settings. Alternatively, the command may be automatically generated by the controller 116 in response to input data from sensors on the vehicle 102. Such data may reflect external conditions, such as the distance to oncoming traffic, ambient lighting, vehicle pitch, and vehicle speed. The controller 116 may process this sensor data and issue the command to optimize the light system 104 without requiring user intervention.

[0072] Upon receiving 1202 the command, the controller 116 may continue the process 1200 by validating 1204 the command to ensure its appropriateness. Validating 1204 the command may involve verifying the source of the command, ensuring it aligns with the operational parameters of the light system 104, or checking that the command does not conflict with other functions of the vehicle 102. Validating 1204 the command provides a safeguard against unintended or erroneous commands that could otherwise lead to improper actuation of the light system 104.

[0073] After validating 1204 the command, the controller 116 may continue the process 1200 by determining 1206 actuation to preserve the virtual pivot point 214. In determining 1206 actuation to preserve the virtual pivot point 214, the controller 116 may calculate the required actuation in the actuation system 210 to adjust direction of the light 106 while preserving thevirtual pivot point 214 through which the light 106 passes. This calculation may be based on the light module position 212 which may be determined from the position sensor 246, and the desired position of the virtual pivot point 214 relative to the vehicle component 110. In light systems 104 with a single actuator, the controller 116 may calculate the precise adjustment required for the actuator to align the light module 200. For systems with two or more independently adjustable actuators, the controller 116 may determine distinct adjustments for each actuator to achieve the desired alignment.

[0074] The controller 116 may continue the process 1200 by executing 1208 actuation differentiating distances in the actuation system 210 to preserve the virtual pivot point 214. In executing 1208 actuation differentiating distances in the actuation system 210 to preserve the virtual pivot point 214, the controller 116 may signal the actuation system 210 to move the light module 200. For systems with a single actuator, the adjustment may involve moving the actuator to a calculated position so that the virtual pivot point 214 is maintained. For systems with multiple actuators, the controller 116 may independently adjust each actuator to accommodate varying distances or angles, ensuring the virtual pivot point 214 remains aligned to the desired position relative to the vehicle component 110.

[0075] The controller 116 may continue the process 1200 by validating 1210 the position of components of the light system 104 by checking data from the position sensor 246. The position sensor 246 may provide real-time feedback on the position of the light module 200 and / or components of the actuation system 210. Validation ensures that adjustments have been performed accurately and that the light module 200 is in the desired position to maintain proper alignment with the virtual pivot point 214.

[0076] The controller 116 may continue the process 1200 by determining 1212 whether the position of components of the light system 104 are within tolerance. In determining 1212 whether the position of components of the light system 104 are within tolerance, the controller 116 may determine whether the position of the light module 200 and / or components of the actuation system 210 are within a predefined tolerance range. If the position is confirmed to be within tolerance, the process 1200 may end, and the system may await the next command. If the position is outside the tolerance range, the process 1200 may return to determining 1206 actuation to preserve the virtual pivot point 214. This iterative approach ensures the alignment is continuously refined until it meets precision requirements of the light system 104.

[0077] The steps of validating 1204 the command, validating 1210 position of components of the light system 104, and / or determining 1212 whether the position of the components of the light system 104 are within tolerance may be considered optional and may be omitted based on thespecific design or functionality of the light system 104. For example, validating 1204 the command may not be required if the system assumes all incoming commands are inherently valid. Similarly, validating 1210 position of components of the light system 104, may be bypassed in systems that rely on pre-calibrated actuator positions and do not utilize real-time sensor feedback. Additionally, determining 1212 whether the position of components of the light system 104 are within tolerance may be omitted in systems where precise alignment is inherently maintained through actuator design or if repeated iterations are unnecessary due to the high accuracy of the initial actuation. These variations may simplify the process 1200 in implementations where additional validation and verification are deemed unnecessary or redundant.ELEMENT LIST
