[0001] Related Applications This invention is a divisional application of Taiwan Patent Application No. 112104030 (filing date: February 6, 2023), and the complete content of this application is incorporated herein by reference as part of the patent specification of this invention.
[0002] The present invention relates to a lighting device, and particularly to an intelligent lighting device. [Background Art]
[0003] Headlights (or front headlights) are equivalent to the eyes of a moving vehicle and are very important for driving safety. In the initial headlights, regardless of whether it is a low beam or a high beam, the provided lighting light pattern is fixed and not appropriately adjusted according to the posture change of the vehicle body when entering a turning corner. Therefore, there are many drawbacks in actual use. For example, when the vehicle is driving on a road with a turning corner, the front lighting light pattern also tilts left or right accordingly, resulting in a lighting dead corner in front of the vehicle, and the driver cannot clearly recognize the situation inside the road, which may cause traffic accidents.
[0004] With the progress of vehicle lighting technology, headlights that can adjust the lighting light pattern have emerged in the market one after another. This type of headlight can adjust the characteristics of the lighting light pattern according to the posture change of the vehicle body. This includes the lighting range, lighting distance, etc., providing the driver with an optimal field of vision and ensuring driving safety. Among them, there are also headlights that use multiple auxiliary lights to provide auxiliary lighting for turning corners, but the volume of the headlight cannot be reduced by installing the auxiliary lights. <[Means for solving the problem]

[Modes for carrying out the invention]
[0028] Embodiments of the "intelligent lighting device" disclosed herein will be described below. Those skilled in the art will be able to understand the merits and effects of the present invention from the published content herein. The present invention can be carried out or applied by other different embodiments. Each section herein can also be modified and altered in equal measure from various viewpoints or applications, as long as it does not deviate from the spirit of the invention. Furthermore, the drawings of the present invention are for simple and schematic purposes only and do not show actual dimensions. Further technical details of the present invention will be described in the following embodiments, but the published content does not limit the present invention. Furthermore, the term "or" as used herein may include any one or more combinations of the relevant items, depending on the actual situation.
[0029] Unless otherwise defined, terms used herein have the same meaning as those commonly understood by the art. Mechanical components and operations relating to each embodiment are, unless otherwise specified, those common in the art.
[0030] [First Embodiment] Please refer to Figures 2 to 5. These show the components and specific arrangement of the intelligent lighting device D according to a first embodiment of the present invention. As shown in the figures above, the intelligent lighting device D of the present invention can be used to provide forward lighting to a vehicle V (e.g., a two-wheeled vehicle such as a motorcycle) and mainly comprises a bracket component 1, a rotating component 2, a drive component 3, a light source component 4, a light source component 5, and a control component 6. The rotating component 2 and the drive component 3 are mounted on the bracket component 1 as a base, and the light source component 4, the light source component 5, and the control component 6 are all coupled to the rotating component 2, thereby forming a single unit.
[0031] As shown in Figures 1 and 8 to 10, in the present invention, the bracket component 1 is fixedly installed on the vehicle V, the rotating component 2 is rotatably installed relative to the bracket component 1, and the drive component 3 is installed between the bracket component 1 and the rotating component 2 to drive the rotating component 2. Furthermore, the light source component 4 is installed inside the rotating component 2 and emits illumination light, and the light projection component 5 is fixed to the rotating component 2 and projects the illumination light outward to form a light distribution pattern P with a horizontal light / dark cutoff line CL. The control component 6 is connected to the rotating component 2 and includes a motion sensor 63. The motion sensor 63 is installed to acquire motion state information of the control component 6. Furthermore, the control component 6 issues a control command to the drive component 3 based on the motion state information acquired from the motion sensor 63, and the drive component 3 performs an operation to rotate the rotating component 2 around the rotation axis A1. Furthermore, the light source component 4, the light projection component 5, and the control component 6 are installed to rotate together with the rotating component 2. Therefore, the intelligent lighting device D of the present invention can achieve low-beam tracking and moving illumination without installing a magnetic encoder internally, thereby reducing manufacturing costs.
[0032] As shown in Figures 9 and 10, the intelligent lighting device D of the present invention can provide sufficient forward illumination when the vehicle V undergoes a change in posture (for example, when the vehicle V tilts to the left or right at a certain angle θ with respect to the road surface), eliminating the dark area corner Z in front of the vehicle and thereby ensuring traffic safety. Furthermore, as shown in Figures 8 to 10, when the vehicle V undergoes a change in posture, the motion sensor 63 can detect the change in the motion state of the control component 6 (control circuit board 61) caused by the change in the posture of the vehicle V. For example, it can detect changes in the direction, speed, and / or acceleration of the vertical movement of the control component 6 (control circuit board 61). The control component 6 (control circuit board 61) then generates a control command for the drive component 3 to drive the rotating component 2 with an appropriate rotational operation in response to the different motion states. The control command includes the drive direction (e.g., rotational direction) and the drive amount (e.g., rotational drive amount), and this control command is transmitted to the drive component 3. In this way, the rotating component 2, driven by the drive component 3, rotates the light source component 4 (solid light source 41), the light projection component 5, and the control component 6 (control circuit board 61) clockwise or counterclockwise by a predetermined angle α, thereby rotating the light distribution pattern P to the correct position and keeping the light and dark cutoff line CL of the light distribution pattern P parallel to the horizontal line HH.
[0033] The components of the intelligent lighting device D of the present invention and the constraints and cooperative relationships between them are described in detail below.
[0034] Referring to Figures 2 to 5, and further to Figures 7, 11, and 12, the bracket component 1 is the assembly base for the entire lighting device, and not only stably mounts the entire lighting device to the vehicle body V, but also integrates the drive component 3 inside the rotating component 2, enabling the drive component 3 to directly drive the rotating component 2 without the need for a transmission mechanism such as a transmission shaft or gear assembly. The bracket component 1 may include a support portion 11, a support portion 12 extending from the support portion 11, and a mounting slot 100 that penetrates the support portion 11 and the support portion 12. The support portion 11 can be coupled to the vehicle body, the support portion 12 can stably hold the drive component 3 in the internal space of the rotating component 2, and the mounting slot 100 can realize rotational coordinated connection between the rotating component 2 and the bracket component 1.
[0035] More specifically, the support portion 11 includes a support frame 111 and a support arm 112 that extends from the outer circumference of the support frame 111. This allows the support portion 11 to have the structural strength of the entire lighting device. Furthermore, the support arm 112 has a fixing hole H, which allows it to be locked and positioned on the body of the vehicle V. In addition, the support portion 12 has a sleeve structure, and the support portion 12 is formed by extending from the side surface of the support frame 111, with the extension direction of the support portion 12 being perpendicular to the extension direction of the support arm 112. However, the above are merely possible embodiments and do not limit the present invention.
[0036] The rotating part 2 is an operating part for the tracking and moving light, and the rotating part 2 may include a shell part 21, a base part 22 installed within the shell part 21, and a shaft part 23 extending from the base part 22. The shell part 21 is configured to enclose a housing space for housing the bracket part 1, the drive part 3, and the light source part 4. The shell part 21 can fix the light-emitting part 5. The base part 22 is for positioning the light source part 4 so that the light-emitting part 5 is located in the light-emitting path of the light source part 4. The shaft part 23 is pivotally attached to the mounting slot 100 of the support part 12 and is used to define the rotation axis A1. More specifically, the shell part 21 is a cylindrical structure with both ends open, and the base part 22 is a flat plate structure, but the present invention is not limited thereto.
[0037] In this embodiment, in the rotating part 2, the base portion 22 divides the housing space of the shell portion 21 into a first housing space S1 and a second housing space S2. The first housing space S1 is located on the side (e.g., the front) of the base portion 22, and the second housing space S2 is located on the other side (e.g., the rear) of the base portion 22, with the shaft portion 23 extending from the base portion 22 into the second housing space S2. After assembly is complete, the support portion 12 and drive portion 3 of the bracket part 1 are located in the second housing space S2, the support portion 12 of the bracket part 1 is located between the shell portion 21 and the shaft portion 23 of the rotating part 2, and the light source component 4 is located in the first housing space S1. It should be noted that the drive portion 3 can also be installed between the support portion 12 of the bracket part 1 and the shell portion 21 of the rotating part 2 (see Figure 5), or between the support portion 12 of the bracket part 1 and the shaft portion 23 of the rotating part 2 (see Figure 11). Therefore, beneficial technical effects can be obtained, such as a compact layout, small footprint, high assembly efficiency, and stable operation.
[0038] As shown in Figures 5, 7, 11, and 12, the drive component 3 is the driving force source for the entire lighting device, and the drive component 3 may include an electromagnetic assembly 31 and a magnetic member 32. The electromagnetic assembly 31 and the magnetic member 32 work together to generate electromagnetic torque, causing the rotating component 2 to rotate clockwise or counterclockwise around the rotation axis A1. More specifically, the electromagnetic assembly 31 may include an iron core 311 and a plurality of coil windings 312. The iron core 311 has an annular portion 3111 and a plurality of foot portions 3112, the foot portions 3112 extending from the inner or outer circumference of the annular portion 3111 and distributed at predetermined intervals, and the plurality of coil windings 312 are each wound around the plurality of foot portions 3112. In practice, as shown in Figures 5 and 7, the annular portion 3111 of the iron core 311 can be fixed to the shell portion 21 of the rotating part 2, and the magnetic member 32 can be fixed to the support portion 12 of the bracket part 1, and positioned opposite to the multiple foot portions 3112 of the iron core 311. Alternatively, as shown in Figures 11 and 12, the annular portion 3111 of the iron core 311 can be fixed to the shaft portion 23 of the rotating part 2, and the magnetic member 32 can be fixed to the support portion 12 of the bracket part 1, and positioned opposite to the multiple foot portions 3112 of the iron core 311. The magnetic member 32 can consist of a single magnet or multiple magnets, but the present invention is not limited thereto.
[0039] To make the rotation of the rotating part 2 more stable and smoother, a bearing unit B can be installed between the bracket part 1 and the rotating part 2. The bearing unit B can be a thin-walled ball bearing, but the present invention is not limited thereto. When the drive component 3 is positioned between the support part 12 of the bracket part 1 and the shell part 21 of the rotating part 2, the bearing unit B is positioned between the support part 12 of the bracket part 1 and the shaft part 23 of the rotating part 2, as shown in Figures 5 and 7. When the drive component 3 is positioned between the support part 12 of the bracket part 1 and the shaft part 23 of the rotating part 2, the bearing unit B is positioned between the support part 12 of the bracket part 1 and the shell part 21 of the rotating part 2, as shown in Figures 11 and 12. However, these are merely feasible embodiments and do not limit the present invention. More preferably, the positions of the iron core 311, the magnetic member 32, and the bearing unit B correspond, and the geometric centers CP of the annular part 3111 of the iron core 311, the magnetic member 32, and the bearing unit B coincide on the rotation axis A1. In this way, optimal structural stability can be achieved with just one bearing unit B.
[0040] The light source component 4 may include a solid light source 41 and a conductive substrate 42, the solid light source 41 being mounted on the conductive substrate 42. In practice, the rotating component 2 has a mounting surface 200 for installing the light source component 4 in a first housing space S1, and the light source component 4 can rotate together with the rotating component 2. The solid light source 41 may include one or more light-emitting units such as light-emitting diodes. The conductive substrate 42 is a circuit board, more preferably a highly thermally conductive printed circuit board, such as a metal substrate printed circuit board (MCPCB). This can drive and light up the solid light source 41 according to a control command, and can light up one or more light-emitting units, for example, to generate a required low-beam or high-beam light distribution pattern.
[0041] Incidentally, the mounting surface 200 installed on the base portion 22 of the rotating part 2 can provide a sufficient heat dissipation area. In addition to the use of a metal substrate printed circuit board as the conductive substrate 42, which forms the shortest heat transfer path between the solid light source 41 and the rotating part 2, the material of the rotating part 2 contains a metal with high thermal conductivity, which efficiently enhances heat dissipation and allows the heat generated by the solid light source 41 to be quickly and uniformly dissipated to the outside.
[0042] The light-emitting component 5 is fixed to the shell portion 21 and is located in the light-emitting path of the light source component 4. The light-emitting component 5 has an incident surface 501 and an exit surface 502 opposite to the incident surface 501. The light-emitting component 5 is designed so that light from the solid light source 41 enters the light-emitting component 5 through the incident surface 501 and exits from different positions on the exit surface 502, thereby generating a light distribution pattern P that conforms to vehicle lighting regulations. For example, it conforms to ECE R112 and R113 regulations (asymmetric and symmetric headlight regulations). Furthermore, as shown in Figures 5 and 11, the shell portion 21 of the rotating component 2 has an open end 211 that communicates with a first housing space S1, and the light-emitting component 5 is mechanically coupled to the open end 211 and can rotate together with the rotating component 2.
[0043] In this embodiment, the light-emitting component 5 is an optical lens, with an incident surface 501 being a flat plane and an exit surface 502 being an optical curved surface with different curvatures. Under this optical structure, the light-emitting component 5 defines the optical axis A2 of the solid light source 41, and its incident surface 501 is positioned relative to the light-emitting surface 410 of the solid light source 41. Furthermore, the optical axis A2 of the light-emitting component 5 is parallel to the rotation axis A1 of the rotating component 2, and more preferably essentially coincides with the rotation axis A1 of the rotating component 2. This reduces controllable errors in the rotational operation of the rotating component 2 and improves the adjustment accuracy of the rotation angle of the light-emitting component 5. The term "essentially coincides" means that the optical axis A2 of the light-emitting component 5 is positionally coincidental with, or close to, the rotation axis A1 of the rotating component 2.
[0044] As shown in Figures 5, 8, and 10, the control component 6 is the core of the control of the entire lighting system and includes a control circuit board 61, a processing unit 62, and the aforementioned motion sensor 63. The processing unit 62 is integrated with the control circuit board 61 together with the motion sensor 63. The control circuit board 61 is installed to rotate by a rotating component 2, and the motion sensor 63 senses changes in the motion state of the control circuit board 61 (the motion state of the control circuit board 61 changes according to the change in the attitude of the vehicle V). Based on the information obtained from the motion sensor 63, the processing unit 62 issues a control command corresponding to the drive component 3, causing the drive component 3 to rotate the rotating component 2 at a predetermined angle, thereby eliminating or reducing the dark areas D of the lighting caused by the change in the attitude of the vehicle V.
[0045] In practical applications, the rotating component 2 may further include a retaining portion 24 for fixing the control circuit board 61. This allows the control circuit board 61 to rotate together with the rotating component 2. The retaining portion 24 includes a support plate 241 and a bonding sleeve 242, the bonding sleeve 242 extending from the side of the support plate 241. The support plate 241 is installed to be integrated with the control circuit board 61. For example, the support plate 241 is provided with one or more fixing structures (e.g., hollow columnar structures) to restrict the movement of the control circuit board 61. The bonding sleeve 242 is attached to and coupled with the shaft portion 23. However, the above describes only possible embodiments and does not limit the invention.
[0046] In this embodiment, the shaft portion 23 has a front section close to the base portion 22 and a rear section that moves away from the base portion 22. After assembly is complete, the shaft portion 23 passes through the mounting slot 100 of the bracket component 1, and the bonding sleeve 242 extends at least partially into the mounting slot 100 and is mechanically coupled to the rear section of the shaft portion 23. Furthermore, the electromagnetic assembly 31 and magnetic member 32 of the drive component 3 are installed sequentially perpendicular to the direction of the rotation axis A1 in the front section of the shaft portion 23. That is, they are installed sequentially from top to bottom or bottom to top.
[0047] As shown in Figures 5 and 6, the rotating part 2 is installed to enable the transmission of power and signals between the light source part 4 and the vehicle V, between the light source part 4 and the control part 6, and between the drive part 3 and the control part 6.

Furthermore, the control component 6 is installed to issue control commands to the drive component 3 based on the information acquired from the motion sensor 63. As a result, under the drive of the drive component 3, the rotating component 2 rotates the light source component 4, the light projection component 5, and the control component 6 to a predetermined angle in a clockwise or counterclockwise direction, thereby rotating the light distribution pattern P to the desired position. This ensures that the light and dark cutoff line CL of the light distribution pattern P is kept flat (parallel to the horizontal line HH).

The light guide unit 43 is located in a position corresponding to the solid light source 41 and has a reflective surface 430. The reflective surface 430 is positioned facing the light-emitting surface 410 of the solid light source 41 and reflects the illumination light emitted from the solid light source 41, directing it toward the incident surface 501 of the light projection component 5. The reflective surface 430 of the light guide unit 43 can be a curved surface constructed based on an elliptic curve, but the present invention is not limited thereto.
[0052] In this embodiment, the light source component 4 also includes an adapter plate 44, which is installed to form an electrical connection between the conductive substrate 42 and the control circuit board 61. Furthermore, the rotating component 2 also has a second mounting surface 200b located within the first housing space S1, the second mounting surface 200b is connected to the first mounting surface 200a, is perpendicular to each other, and the second mounting surface 200b is installed on the base portion 22 to position the adapter plate 44. Under this structure, the adapter plate 44 is a circuit board, and the wire W1 from the vehicle body side is connected to the adapter plate 44, thereby further electrically connecting it to the conductive substrate 42. Similarly, the wire W2 from the control circuit board 61 is connected to the adapter plate 44, thereby further electrically connecting it to the conductive substrate 42.
[0053] As shown in Figure 13, to enhance reliability, the intelligent lighting device D of the present invention further includes a mask 7, which encloses the control component 6 internally, keeping it isolated from the outside world and making it less susceptible to external environmental factors such as dust, moisture, and water. The mask 7 seals the second housing space S2 of the shell portion 21 and, together with the support plate 241 of the holding portion 24, forms a closed space 700, and is installed to position the control component 6 within the closed space 700.

A second sealing plug 8b is installed in the second wiring hole 220 to fill the remaining space other than the space occupied by the lead wire W3. Furthermore, a first sealing gasket 9a is installed between the shell portion 21 of the rotating part 2 and the light-emitting part 5 (joint location), and the first sealing gasket 9a is installed along the contour of the edge of the light-emitting part 5. A second sealing gasket 9b is installed between the shaft portion 23 of the rotating part 2 and the bonding sleeve 242 of the holding portion 24 (joint location), and the second sealing gasket 9b is installed around the outer circumference of the wiring path 201.
