Abstract

A headlight includes a projector module held by a carrier designed to move. The carrier may include a bezel having openings for the projector modules. These openings may receive a lens covering the projector module. The headlight may include an additional projector module that surrounds or at least partially surrounds the bezel and the aforementioned projector module. Movement of the carrier and the bezel causes the lenses to move, and the movement of the lenses causes articulation of the respective beams of the projector modules.

[0024] The specific embodiments set forth below are intended to describe various configurations of the subject technology and are not intended to represent the only configurations in which the subject technology can be practiced. The accompanying drawings are incorporated herein and constitute a part of the specific embodiments. An appendix is also attached, through which one or more specific implementations of the subject technology can be implemented. The specific embodiments include specific details in order to provide a thorough understanding of the subject technology. However, the subject technology is not limited to the specific details set forth herein and can be practiced using one or more other specific implementations. In one or more specific implementations, well-known structures and components are shown in block diagram form to avoid confusion with the various concepts of the subject technology.

[0025] The present disclosure relates to lights (including headlights) for vehicles. The lights described herein may include one or more projector modules (or simply projectors) that act as light sources. Depending on the desired light intensity (e.g., low beam, high beam) or driving mode, the number of projector modules that are illuminated (e.g., generate light) may vary. The light may also include a carrier designed to hold the projector modules, including corresponding lenses covering these modules. The light may include additional projector modules (e.g., stadium projectors) surrounding the aforementioned modules. In one or more specific embodiments, the carrier is movable relative to the additional projector modules, thereby allowing the corresponding beams (e.g., light beams) of the projector modules (including the beam paths of the beams) to be articulated. The articulation of the beams can be used to adapt to the construction tolerances of the vehicle components and / or to change the beam paths (e.g., light beam paths) of the projector modules when adjusting the ground clearance of the vehicle. Additionally, the beams of the projector modules can be articulated to provide adaptive drive beams to adapt to changes in the movement (e.g., driving direction) of the vehicle. The articulation of the beam may be due in part to movement of the lens (held by the carrier) or to movement of the projector module itself.

[0026] Figure 1 An example of a vehicle 100 according to aspects of the present disclosure is illustrated. In one or more implementations, the vehicle 100 is a sport utility vehicle (SUV). Figure 1 In the exemplary implementation shown, vehicle 100 is a truck. Generally speaking, vehicle 100 can take the form of any motor vehicle, including motor vehicles having an internal combustion engine and / or one or more electric motors. Thus, other implementations of vehicle 100 may include land-based vehicles, such as, by way of non-limiting example, a car (e.g., a sedan, a hatchback), a van, or a commercial truck.

[0027] The vehicle 100 may include a battery pack 102. The battery pack 102 may be coupled (e.g., electrically coupled) to one or more power systems of the vehicle 100 to provide power to the one or more electrical systems. The vehicle 100 may also include a port 104 (e.g., a charging port) that is designed to receive a cable connector (e.g., a charging port) for delivering power (e.g., alternating current (AC) power). Figure 1 112a ), which is converted into direct current (DC) power to charge the battery pack 102. The battery pack 102 may be coupled (e.g., electrically coupled) to a drive unit 110, which represents one or more drive units of the vehicle 100. Although the drive unit 110 is shown as being generally located at the front of the vehicle 100, the drive unit 110 may be located at the rear of the vehicle 100. When multiple drive units are implemented in the vehicle 100, at least one drive unit may be located at the front of the vehicle 100 and at least one drive unit may be located at the rear of the vehicle 100. Furthermore, when multiple drive units are used, at least one drive unit may be at the front of the vehicle to drive the front wheels (e.g., wheels 112a ) and at least one drive unit may be at the rear of the vehicle to drive the rear wheels (e.g., wheels 112b ). The drive unit 110 may include, for example, a motor, an inverter, a gearbox, and a differential. In Figure 1 In the example shown, the drive unit 110 is in the form of an electric motor. In this regard, the drive unit 110 can use the energy (e.g., electrical energy) stored in the battery pack 102 for propulsion, so as to drive (e.g., rotationally drive) the wheels of the vehicle 100, thereby causing the vehicle 100 to move.

[0028] Figure 2A front view of a vehicle 100 according to one or more aspects of the present disclosure is illustrated. Vehicle 100 may include several lights. For example, in one or more specific implementations, vehicle 100 includes light 120a, light 120b, and light 120c. Each of lights 120a, 120b, and 120c may include one or more projector modules or projectors that provide one or more light sources designed to illuminate passengers in a cabin 128 of vehicle 100 and increase visibility. For example, light 120a (representing light 120c) includes projector module 122a, projector module 122b, and projector module 122c. Additionally, light 120a may also include projector module 122d, which surrounds or at least partially surrounds projector modules 122a, 122b, and 122c. Light 120a may also include an extension 123 or portion that provides an additional projector module. Additionally, the light 120b may include a projector module (shown, not labeled). As non-limiting examples, the projector module shown and / or described herein may take the form of an LED or an incandescent light bulb. The lights 120a and 120c may be referred to as headlights or headlamps, and the light 120b may be referred to as a centerlight. The vehicle 100 may also include a battery pack 102 ( Figure 1 ) that provides energy (e.g., electrical energy) to illuminate projector modules 122a, 122b, 122c, and 122d and Figure 2 Other projector modules shown and / or described. However, in one or more implementations, the vehicle 100 includes a separate power source (eg, a 12 volt battery) to illuminate the aforementioned projector modules.

[0029] Additionally, the vehicle 100 may include a sensor 126. In one or more specific implementations, the sensor 126 takes the form of a ground clearance sensor. Thus, the sensor 126 can determine the current height of the vehicle 100 (e.g., current ground clearance) and changes in the height of the vehicle 100 relative to, for example, the road or surface on which the vehicle 100 is located. As shown, the sensor 126 is located at or substantially at the front of the vehicle 100. Although not shown, the vehicle 100 may also include a sensor located at or substantially at the front of the vehicle 100, wherein the sensor includes any of the features and / or characteristics described for the sensor 126.

[0030] The vehicle 100 may include a suspension system, shown as including suspension unit 127a and suspension unit 127b (each representing one or more additional suspension units), capable of adjusting areas of the vehicle 100, such as the cabin 128 (e.g., passenger space) and / or the chassis ( Figure 2 (not shown in the figure). In one or more specific implementations, each of the suspension units 127a and 127b is in the form of an air suspension unit or an air lift suspension unit, and the suspension system is in the form of an air suspension system. Conversely, in one or more specific implementations, each of the suspension units 127a and 127b is in the form of a shock absorber and strut system, and the suspension system is in the form of a standard suspension system.

[0031] When the vehicle 100 moves in either direction of the double-headed arrow 130, the sensor 126 determines the current height of the vehicle 100. When the suspension system is in the form of an air suspension system, the lights 120a and 120b (including their corresponding projector modules) can automatically articulate and re-level in response to the change in height above the ground. In contrast, when the suspension system is in the form of a standard suspension system, the vehicle 100 can use the information provided by the sensor 126 (e.g., current height data) to articulate at least some of the beams (e.g., light beams) from the corresponding projector modules of the lights 120a and 120b, thereby causing a change in the direction (e.g., angular direction) of the light emitted from the corresponding beams. For example, the vehicle 100 can articulate the corresponding beams of the projector modules 122a, 122b, and 122c based on the current height above the ground of the vehicle 100 (along the double-headed arrow 130). In this regard, the vehicle may include motors 131a and 131b that are designed to articulate lights 120a and 120b, respectively, thereby causing a change in the direction (e.g., angular direction) of light emitted from the respective beams of lights 120a and 120b. As non-limiting examples, each of motors 131a and 131b may take the form of a DC motor, including a stepper motor or a servo motor. The degree or angle at which the projector modules 122a, 122b, and 122c project light may vary based on the height of the vehicle 100 from the ground. In this regard, as the height of the vehicle increases, the projector modules 122a, 122b, and 122c may be tilted lower (e.g., the angle decreases), and conversely, as the height of the vehicle decreases, the projector modules 122a, 122b, and 122c may be tilted higher (e.g., the angle increases). Additionally, when implemented as a ground clearance sensor, sensor 126 can be used by vehicle 100 to adjust the ground clearance of vehicle 100 while vehicle 100 is operating. For example, when vehicle 100 reaches or exceeds a predetermined speed (e.g., 65 miles per hour), vehicle 100 can lower ground clearance. Sensor 126 can be used as an input to vehicle 100 to determine the current ground clearance of vehicle 100, which can then be used by vehicle 100 to articulate the respective beams of projector modules 122a, 122b, and 122c.

[0032] In addition, vehicle 100 may include additional sensors and / or receive additional data to determine the movement (e.g., direction of travel) of vehicle 100. Accordingly, vehicle 100 may articulate the corresponding beams of projector modules 122a, 122b, and 122c in either direction of bidirectional arrow 132. For example, when vehicle 100 turns left or right, the corresponding beams of projector modules 122a, 122b, and 122c may adjust left or right, respectively, thereby providing adaptive drive beams that adjust to the surface on which vehicle 100 is traveling to better illuminate the surface in front of vehicle 100. Furthermore, the operating mode of vehicle 100 may change based on changes to the driving mode, where exemplary driving modes include, but are not limited to, road, off-road, general, conservative, sport, and snow modes. Based on the driving mode selected for vehicle 100, vehicle 100 may articulate the corresponding beams of projector modules 122a, 122b, and 122c for the selected driving mode.

[0033] Figure 3 A perspective view of a lamp 120a according to one or more aspects of the present disclosure is illustrated. The lamp 120a may be referred to as a device. Thus, the devices described herein may be used in a vehicle (e.g., Figure 2 For simplicity, the extended portion 123 ( Figure 2 ). Lamp 120a may include a carrier 136 designed to hold several components of lamp 120a. In one or more specific implementations, carrier 136 takes the form of an integral carrier. For example, carrier 136 may include a single-piece carrier formed from a molded material (e.g., a molded plastic material) and taking the form of an integral carrier. Carrier 136 may hold projector modules 122a, 122b, and 122c, or at least provide space for these projector modules. Additionally, carrier 136 may hold lenses 138a, 138b, and 138c. Each of lenses 138a, 138b, and 138c may include a transparent material, such as transparent plastic. As shown, lens 138a, lens 138b, and lens 138c cover projector module 122a, projector module 122b, and projector module 122c, respectively.

[0034] One or more of the projector modules 122a, 122b, and 122c may illuminate and provide a light beam. Figure 2122c). For example, each of projector modules 122a and 122b can illuminate to provide a low-beam mode to vehicle 100, the low-beam mode providing a light intensity based on the illumination of projector modules 122a and 122b. Optionally, each of projector modules 122a, 122b, and 122c can illuminate to provide a high-beam mode to vehicle 100, the high-beam mode providing a light intensity based on the illumination of projector modules 122a, 122b, and 122c, wherein the high-beam mode provides a greater light intensity than the low-beam mode. In one or more specific implementations, projector module 122d illuminates independently of the illumination of projector modules 122a, 122b, and 122c.

[0035] Carrier 136 may include a frame 140. Each of projector modules 122a, 122b, and 122c and each of lenses 138a, 138b, and 138c may be aligned with corresponding openings of frame 140. For example, frame 140 may include opening 142a, opening 142b, and opening 142c. As shown, projector module 122a and lens 138a are aligned with opening 142a, projector module 122b and lens 138b are aligned with opening 142b, and projector module 122c and lens 138c are aligned with opening 142c. In addition, lens 138a, lens 138b, and lens 138c may protrude or at least partially protrude through opening 142a, opening 142b, and opening 142c, respectively. In this regard, carrier 136 (including frame 140) is designed to carry at least lenses 138a, 138b, and 138c.

[0036] As shown, openings 142a, 142b, and 142c may comprise a rectangular shape. In this regard, opening 142a (representing openings 142b and 142c) may comprise a dimension 144a (e.g., height) and a dimension 144b (e.g., width). In one or more specific implementations, dimension 144a (e.g., height) is approximately in the range of 15 millimeters (mm) to 30 mm, and dimension 144b is approximately in the range of 55 mm to 70 mm. Dimension 144a may be 20 mm, and dimension 144b may be 50 mm. Thus, dimension 144b may be at least twice as large as dimension 144a.

[0037] Based on dimension 144a of opening 142a, the corresponding dimension (e.g., height) of lens 138a (located in opening 142a) may be no greater than dimension 144a. Furthermore, to ensure that lens 138a fits within opening 142a, the corresponding dimension of lens 138a may be smaller than dimension 144a. Reducing the lens height may reduce the light emitted from the optical system (e.g., projector module 122a), resulting in a loss in beam reach and width (e.g., the beam reach and width from projector module 122a). To offset this loss in beam reach and width and achieve or exceed an acceptable safety rating from a rating agency, the source lumens in the projector module (e.g., projector module 122a) may be increased. Thus, the percentage increase in source lumens may be inversely proportional to the lens height.

[0038] Figure 4 An exploded view of a lamp 120a according to one or more aspects of the present disclosure is illustrated. The lamp 120a may include a cover 146. In one or more specific embodiments, as non-limiting examples, the cover 146 takes the form of a transparent cover and may be formed from glass, transparent plastic, or a combination thereof. The lamp 120a may also include a housing 148. As non-limiting examples, the housing 148 may include one or more opaque materials, such as metal, opaque plastic, or a combination thereof. In one or more specific embodiments, each of the cover 146 and the projector module 122d is connected to or mated with the housing 148. When the lamp 120a is assembled, the cover 146 may cover the housing 148. In addition, the housing 148 may define a space 150 to accommodate the carrier 136 (including the frame), the projector modules 122a, 122b, and 122c, and the lenses 138a, 138b, and 138c. In this regard, the cover 146 may cover the projector modules 122a, 122b, and 122c, the carrier 136, and the lenses 138a, 138b, and 138c.

[0039] Additionally, projector module 122a may be adjacent to projector module 122b, and projector module 122b may be adjacent to projector module 122c. Two components or structures may be "adjacent" to one another when there are no intervening components or structures. Additionally, lens 138a may be adjacent to lens 138b, and lens 138b may be adjacent to lens 138c. Additionally, opening 142a may be adjacent to opening 142b, and opening 142b may be adjacent to opening 142c.

[0040] Projector module 122d may include a rectangular shape resembling a stadium. In this regard, projector module 122d may be referred to as a stadium projector module or stadium projector. Based on this shape, projector module 122d may include a space 154 or volume that provides a location for carrier 136 and frame 140. Thus, projector module 122d may define at least a space (e.g., space 154) for frame 140. Additionally, carrier 136 and frame 140 may each include a shape corresponding to the shape of projector module 122d. In this regard, carrier 136 and frame 140 may each include a rectangular shape. Furthermore, when lenses 138a, 138b, and 138c are positioned within openings 142a, 142b, and 142c, respectively, of bezel 140, projector modules 122a, 122b, and 122c are held by carrier 136, and carrier 136 (including bezel 140) is disposed within space 154. Projector module 122d also provides space (e.g., space 154) for projector modules 122a, 122b, and 122c and lenses 138a, 138b, and 138c. Furthermore, when lamp 120a is assembled, carrier 136 (including bezel 140), projector modules 122a, 122b, and 122c, and lenses 138a, 138b, and 138c may be disposed, or at least partially disposed, within space 150 defined by housing 148.

[0041] Figure 5 A partial cross-sectional view of a lamp 120a according to one or more aspects of the present disclosure is illustrated. For simplicity and illustration purposes, the cover 146 (in Figure 4 142c).

[0042] To articulate the respective beam paths of projector modules 122a, 122b, and 122c, carrier 136 may be configured to move. For example, carrier 136 (including frame 140) may be movable in either direction of bidirectional arrow 130 (e.g., about the X-axis of Cartesian coordinates). Movement of carrier 136 along either direction of bidirectional arrow 130 may cause corresponding movement of lenses 138a, 138b, and 138c, thereby causing the respective beam paths of projector modules 122a, 122b, and 122c to change. As non-limiting examples, movement of carrier 136 may be used to adjust for construction tolerances during vehicle assembly, variations in the height of vehicle 100 from the ground (e.g., the vehicle's 100 height above the ground, and the vehicle's 100 height above the ground). Figure 5 ) or a change in the operating mode of the vehicle 100 (e.g., a driving mode). Additionally, the carrier 136 (including the frame 140) can move in either direction of the bidirectional arrow 132 (e.g., about the Z axis). Movement of the carrier 136 along either direction of the bidirectional arrow 132 can cause corresponding movement of the lenses 138a, 138b, and 138c, thereby articulating the beam paths of the projector modules 122a, 122b, and 122c and causing the beam paths to move in the corresponding directions. As a non-limiting example, the carrier 136 can move in response to movement of the vehicle 100. The movement of the carrier 136 can be used to adjust the beam paths of the projector modules 122a, 122b, and 122c for adaptive drive beams. In this regard, each of the projector modules 122a, 122b, and 122c can be referred to as an adaptive drive projector module.

[0043] Projector module 122d can be coupled to housing 148. To articulate the respective beam paths of projector modules 122a, 122b, and 122c, carrier 136 (including bezel 140) and lenses 138a, 138b, and 138c can move relative to or independently of projector module 122d. Additionally, in one or more implementations, projector modules 122a, 122b, and 122c can remain stationary based on the articulation of the beam paths of projector modules 122a, 122b, and 122c by moving lenses 138a, 138b, and 138c, respectively, and carrier 136 (including bezel 140). However, in one or more implementations, projector modules 122a, 122b, and 122c themselves move based on the movement of carrier 136 (including bezel 140) and lenses 138a, 138b, and 138c. In this regard, projector modules 122a, 122b, and 122c may be movable relative to projector module 122d.

[0044] Figure 6A and Figure 6BA perspective view of the projector module 122a and lens 138a is illustrated, showing articulation of the beam 156 (e.g., light beam) of the projector module 122a based on movement of the lens 138a, according to one or more aspects of the present disclosure. Figure 6A and Figure 6B The example embodiment shown and described in FIG. 1 shows that the lens 138a moves relative to the projector module 122a to articulate the beam 156 generated by the projector module 122a. It should be noted that Figure 6A and Figure 6B The relationship between projector module 122a and lens 138a shown in FIG. 1 is representative of other projector module and lens pairs shown and / or described herein.

[0045] refer to Figure 6A , lens 138a moves angle 158. Angle 158 may be in the range of approximately 3 degrees to 15 degrees relative to horizontal line 160. Based on the movement of lens 138a to angle 158, beam 156 may be articulated at an angle equal to angle 158. Figure 6A As shown, beam 156 is articulated downward (eg, negatively along the Z-axis).
