Description

Technical Field

[0001] This technology relates to the field of automotive lighting technology, and in particular to a lighting adjustment mechanism, a lighting fixture, and a vehicle. Background Technology

[0002] In existing technology, high and low beam headlights are switched by adjusting the tilt angle of the headlights. When the headlights are parallel to the horizontal plane, the headlight light source shines directly forward, which is the high beam headlight; when the headlights are tilted downwards, the headlight light source shines towards the ground, which is the low beam headlight.

[0003] In existing vehicle lighting solutions, manual adjustment or a dimming motor can be used to dim the light source. When using a dimming motor for dimming, the adjustable distance and angle of the dimming motor are very small due to the limited internal space of the vehicle lighting. Therefore, a manual dimming screw needs to be connected and assembled at the rear of the dimming motor away from the light-emitting side through an adapter bracket (forming a combined component of dimming motor, adapter bracket, and manual dimming screw). When a large-angle dimming is required, two steps need to be performed: (1) First, operate the manual dimming screw to drive the adapter bracket and dimming motor to make linear motion, so as to push or pull the light source to rotate around the axis (rotation around the axis here refers to rotation around the linear axis where a certain fulcrum is located as the dimming axis), so that the illumination angle of the light source deflects by an angle a1; (2) Then start the dimming motor, and drive the light source to deflect by extending or retracting the extension end of the dimming motor. At this time, the illumination angle of the light source deflects by a small angle a2; a1+a2 is the total rotation angle of the light source. Therefore, in order to achieve wide-angle dimming, a large design space needs to be reserved for the connected manual dimming screw, adapter bracket, and dimming motor.

[0004] Different lamps have different shapes of internal decorative parts, different internal spaces, and different lens sizes. Therefore, different specifications of motor adapter brackets need to be designed to match the lamps (redesigning and opening new molds for injection molding), which increases production costs. In addition, a separate workstation needs to be reserved for assembling the dimming motor and the adapter bracket, which increases labor costs and affects assembly efficiency.

[0014] In the tilt adjustment mode, the straight axis passing through the center of the third adjustment component along the X direction is the dimming axis I.

[0016] In one embodiment, the bracket is provided with two mounting holes, and the first and second adjustment components are respectively connected to one of the mounting holes;

[0021] A rotary adjustment element is connected to the end of the adjustment rod away from the adjustment nut. The rotary adjustment element is configured to drive the adjustment rod to rotate about its own axis to drive the bracket to offset in the Z direction.

[0022] In one embodiment, the third regulating component includes:

[0023] A ball-head nut is installed on the side of the bracket away from the light-emitting surface of the lamp assembly;

[0024] A telescopic motor, the telescopic motor including a ball end, the ball end being connected to the ball nut.

[0063] In existing automotive lighting solutions, the light source can be dimmed manually or using a dimming motor. When using a dimming motor, the adjustable distance and angle are limited by the internal space of the headlight. Therefore, a manual dimming screw needs to be connected and mounted on the rear of the dimming motor, away from the light-emitting side, via an adapter bracket (forming a combined assembly of the dimming motor, adapter bracket, and manual dimming screw). For large-angle dimming, two steps are required: First, operate the manual dimming screw to drive the adapter bracket and dimming motor in a linear motion, pushing or pulling the light source to rotate around an axis (rotation around an axis refers to rotation about a linear axis containing a fulcrum), causing the illumination angle of the light source to deflect by angle a1. Second, start the dimming motor, using the extension or retraction of its telescopic end to deflect the light source, at which point the illumination angle deflects by a small angle a2. a1 + a2 is the total rotation angle of the light source. Therefore, in order to achieve wide-angle dimming, a large design space needs to be reserved for the connected manual dimming screw, adapter bracket, and dimming motor.

[0064] In addition, adapter brackets often require new molds for injection molding, which reduces their versatility and increases the cost of the lamps. Moreover, the adapter brackets with matching designs occupy a large amount of internal installation space in the vehicle lamps and require additional steps to assemble the motor and the dimming bracket, which increases labor costs and affects assembly efficiency.

[0065] To address the aforementioned technical problems, this application provides a lamp adjustment mechanism, including a lamp assembly and a first adjustment component, a second adjustment component, and a third adjustment component. The lamp assembly includes a bracket and a light source, with the light source mounted on the bracket. The first, second, and third adjustment components are located on the side of the bracket away from the main light emission direction of the light source. All three components are rotatably connected to the bracket. Along the X-direction, the second adjustment component is located to one side of the first adjustment component, and along the Y-direction, the third adjustment component is located to one side of the first adjustment component. One or two of the first, second, and third adjustment components are configured to extend and retract along the Z-direction to drive the bracket to extend and retract along the Z-direction, where the Z-direction is the main light emission direction of the light source. Specifically, when one or two of the three adjustment components extend and retract along the Z-direction, the entire bracket is driven to deflect about the linear axis containing the axes of the other non-operating adjustment components, thereby achieving dimming in space. The above structure does not employ a motor bracket, thus saving on bracket production costs and labor costs for bracket installation, and also improving the assembly efficiency of the lamp.

[0066] In some embodiments, refer to Figures 1 to 11 A lighting adjustment mechanism includes a lamp assembly 10, a first adjustment component 20, a second adjustment component 30, and a third adjustment component 40.

[0067] The lamp assembly 10 includes a bracket 101 and a light source 102. The light source 102 is mounted on the bracket 101, and the main light emission direction of the light source 102 is the Z direction. When adjusting the high and low beams of the lamp, the light source 102 moves together with the bracket 101, that is, the bracket 101 drives the light source 102 to shift, thereby changing the illumination angle of the light source 102 and thus achieving dimming.

[0068] Among them, three adjustment components are located on the side of the bracket 101 away from the main light emission direction of the light source 102. The first adjustment component 20, the second adjustment component 30, and the third adjustment component 40 are used to drive the bracket 101 to move along the Z direction. The first adjustment component 20, the second adjustment component 30, and the third adjustment component 40 are all rotatably connected to the bracket 101. In the X direction, the second adjustment component 30 is located on the side of the first adjustment component 20, and in the Y direction, the third adjustment component 40 is located on the side of the first adjustment component 20. One or two of the first, second, and third adjustment components are configured to extend and retract in the Z direction to drive the bracket 101 to move in the Z direction, where the Z direction is the main light emission direction of the light source 102.

[0069] Specifically, the first adjustment component 20, the second adjustment component 30, and the third adjustment component 40 are all rotatably connected to the bracket 101. This rotatable connection can be achieved through a ball joint hinge, or the first, second, and third adjustment components can be inserted into the bracket 101, with a reserved space at the connection point between the adjustment components and the bracket 101 as a clearance for movement. This reserved space provides the adjustment components with the degree of freedom to offset within the bracket 101, allowing the first, second, and third adjustment components to rotate relative to the bracket 101. In general, when one or two of the first, second, and third adjustment components extend or retract along the Z-direction to drive the bracket 101 to move along the Z-direction, the adjustment components and the bracket 101 are in the XYZ spatial coordinate system (refer to...). Figure 4 and Figure 7 The bracket 101 can rotate relative to the light source 102, and the entire bracket 101 will deflect in space (the light source 102 will deflect along with the bracket 101), thereby changing the illumination angle of the light source 102 and ultimately achieving dimming.

[0070] When dimming is performed in this application, when one or two of the aforementioned first adjustment component 20, second adjustment component 30, and third adjustment component 40 extend or retract along the Z direction, the bracket 101 deflects using the straight axis containing the axis of the adjustment component that has not performed the extension or retraction as the dimming axis. The dimming axis in the vertical direction includes: the straight axis containing the axes of the first adjustment component 20 and second adjustment component 30, and / or the straight axis containing the axis of the third adjustment component 40, as the axis for adjusting the pitch angle in the vertical direction; the dimming axis in the horizontal direction includes: the straight axis containing the axes of the first adjustment component 20 and third adjustment component 40, and / or the straight axis containing the axis of the second adjustment component 30, as the axis for adjusting the left and right deflection angle in the horizontal direction.

[0071] In this application, each adjustment component drives the bracket 101 to rotate along the Z direction around the dimming axis that is not performing an action, thereby enabling the bracket 101 and the light source 102 to deflect in the horizontal direction and tilt in the vertical direction, thereby changing the illumination angle of the light source 102 and ultimately achieving dimming.

[0072] Traditional dimming methods (where a dimming motor is connected to a manual dimming screw via an adapter bracket, forming a unified assembly of the dimming motor, adapter bracket, and manual dimming screw) work as follows: First, the manual dimming screw drives the connected adapter bracket and dimming motor in a linear motion, pushing or pulling the light source to rotate around an axis by a certain angle (this rotation around an axis refers to rotation about a linear axis containing a fulcrum). Then, to increase the dimming angle, the dimming motor is activated, and the extension or retraction of its telescopic end drives the light source to rotate around an axis, thus rotating the light source by a certain angle. The sum of these two rotation angles is the total rotation angle. Therefore, to achieve large-angle dimming, a large design space needs to be reserved for the connected manual dimming screw, adapter bracket, and dimming motor.

[0073] The embodiments of this application do not require the design of an adapter bracket, which can reduce space occupation and make the overall structure of the dimming mechanism more compact; moreover, it saves the production cost of the adapter bracket and the labor cost in the process of installing the adapter bracket, and can also improve the assembly efficiency of the lamp.

[0074] In some implementations, refer to Figure 7 and Figure 8 The lamp adjustment mechanism includes a tilt angle adjustment mode. The bracket 101 tilts forward and backward along the Z direction, and the light source 102 moves together with the bracket 101, thereby changing the illumination angle and illumination height of the light source 102 in the vertical direction.

[0075] Reference Figure 7 and Figure 8The pitch angle adjustment modes include: a forward tilt adjustment mode, in which the straight axis passing through the center of the third adjustment component 40 along the X direction is used as the dimming axis I. Figure 8 The lower left corner shows the dimming axis "Ⅰ" (the direction of "Ⅰ" is perpendicular to the paper). The first and second adjustment components at the top extend synchronously along the Z direction to drive the bracket 101 to tilt forward at an angle of α1.

[0076] Specifically, Figure 8 A1 is a schematic diagram of the forward tilt angle α1 of the bracket 101. The dashed part in the figure represents the initial position of the bracket 101, and the solid part represents the position of the bracket 101 after it tilts forward. When adjusting the illumination angle of the light source 102 in the vertical direction, the first and second adjustment components simultaneously push the bracket 101 to rotate around the dimming axis I. The light source 102 rotates together with the bracket 101. The light source 102 changes from the initial illumination along the parallel direction to illumination by a certain downward offset in the vertical direction.

[0077] The tilt-forward adjustment mode also includes: using a straight axis passing through the center of the first adjustment component 20 and the second adjustment component 30 along the X direction as the dimming axis II. Figure 8 The diagram shows the dimming axis "II" (the direction of "II" is perpendicular to the paper). The third adjustment component 40 is operated to retract in the opposite direction of the Z direction to drive the bracket 101 to tilt forward as a whole, with a tilt angle of α2.

[0078] Specifically, Figure 8 Figure A2 is a schematic diagram of the bracket 101 tilting forward at an angle α2. The dashed line in the figure represents the initial position of the bracket 101, and the solid line represents the position of the bracket 101 after tilting forward. When adjusting the illumination angle of the light source 102 in the vertical direction, the third adjustment component retracts in the opposite direction of the Z direction to drive the bracket 101 to rotate around the dimming axis II. Figure 8 The schematic diagram A2 is a further rotation based on A1, with a rotation angle of α2. The light source 102 rotates together with the bracket 101, and the light source 102 is offset downward in the vertical direction by an angle of α2.

[0079] In general, refer to Figure 8 In section A3, the sum of α1 and α2 is the forward tilt angle α of the support 101. When the support tilts forward by α in the vertical direction, the light source 102 also shifts by α, and the illumination angle of the light source 102 shifts downward by α, thereby realizing the adjustment of the illumination angle in the vertical direction.

[0080] In addition, the above Figure 8The A1 to A2 and A2 to A3 sequences are just one possible adjustment sequence in the forward tilt adjustment mode. In actual lamp adjustment, it is also possible to adjust only one angle, α1 or α2, or to adjust angle α2 first and then angle α1. Referring to the forward tilt adjustment process of A1 to A2 and A2 to A3 described above, other adjustment sequences will not be elaborated upon.

[0081] Reference Figure 9 The pitch adjustment mode also includes a back tilt adjustment mode, which uses the linear axis passing through the center of the third adjustment component 40 along the X direction as the dimming axis I. Figure 9 The lower left corner shows the dimming axis "Ⅰ" (the direction of "Ⅰ" is perpendicular to the paper). The first and second adjustment components at the top retract synchronously in opposite directions along the Z direction to drive the bracket 101 to tilt backward, with a tilt angle of β1.

[0082] Specifically, refer to Figure 9 Figure B1 is a schematic diagram of the bracket 101 tilting backward at an angle β1. The dashed line in the figure represents the initial position of the bracket 101, and the solid line represents the position of the bracket 101 after tilting backward. When adjusting the illumination angle of the light source 102 in the vertical direction, the first and second adjustment components synchronously retract in opposite directions along the Z direction to drive the bracket 101 to rotate around the dimming axis I. The light source 102 rotates together with the bracket 101, and the light source 102 changes from initially illuminating in the parallel direction to illuminating upward at an angle β1 in the vertical direction.

[0083] Reference Figure 9 In B2, the tilt adjustment mode also includes: using a linear axis passing through the axes of the first and second adjustment components along the X direction as the dimming axis II. Figure 9 The diagram shows the dimming axis "II" (the direction of "II" is perpendicular to the paper surface). The third adjustment component 40 extends along the Z direction to drive the bracket 101 to tilt backward at an angle of β2.

[0084] Specifically, Figure 9 Figure B2 is a schematic diagram of the bracket 101 tilting backward at an angle β2. The dashed line in the figure represents the initial position of the bracket 101, and the solid line represents the position of the bracket 101 after tilting backward. When adjusting the illumination angle of the light source 102 in the vertical direction, the third adjustment component extends along the Z direction to drive the bracket 101 to rotate about the dimming axis II. Figure 9 Based on B1, a further rotation is made, with a rotation angle of β2. The light source 102 rotates upward together with the bracket 101, and the light source 102 is offset upward in the vertical direction by an angle of β2.

[0085] In general, refer to Figure 9In B3, the sum of β1 and β2 is the forward tilt angle β of the support 101. The backward tilt β in the vertical direction causes the light source 102 to shift upward by β, and the illumination angle of the light source 102 shifts upward by β, thereby realizing the adjustment of the illumination angle in the vertical direction.

[0086] In addition, the above Figure 9 The B1 to B2 and B2 to B3 adjustments are just one possible sequence in the tilt adjustment mode. In actual lighting adjustments, it's also possible to adjust only one angle, β1 or β2, or to adjust angle β2 first and then angle β1. Referring to the tilt adjustment process described above for B1 to B2 and B2 to B3, other adjustment sequences will not be elaborated upon.

[0087] It should be noted that the various angle adjustments in the above-mentioned tilt angle adjustment modes are not isolated, but rather, according to user needs, the various adjustment methods are mutually constitutive means of changing the direction of the light source 102. For example, the bracket 101, as... Figure 8 In mode A1, a forward tilting motion was performed, at which point the light source 102 was offset downwards. If the user needs the light source 102 to be illuminated parallel to the user in the next step, then a backward tilting motion needs to be applied to the bracket 101. Using the straight axis passing through the center of the third adjustment component 40 along the X direction as the dimming axis I, the first and second adjustment components retract synchronously in opposite directions along the Z direction to drive the bracket 101 to tilt backwards. Figure 9 The backward tilting motion of B1 adjusts the light emission direction of the light source 102 to illuminate in a parallel direction.

[0088] In some embodiments, refer to Figure 7 and Figure 10 and Figure 11 The lighting adjustment mechanism includes a horizontal deflection adjustment mode, that is, in the horizontal direction, the bracket 101 deflects along the Z direction, and the light source 102 moves together with the bracket 101, thereby changing the illumination angle of the light source 102 in the horizontal direction.

[0089] Reference Figure 10 The horizontal deflection adjustment mode includes a right deflection adjustment mode, with the straight axis passing through the center of the first adjustment component 20 and the third adjustment component 40 along the Y direction as the dimming axis III. Figure 10 The upper right corner shows the dimming axis “Ⅲ” (the direction of “Ⅲ” is perpendicular to the paper surface). The second adjustment component 30 drives the bracket 101 to extend along the Z direction, with an extension angle of γ1.

[0090] Specifically, Figure 10C1 is a schematic diagram of the bracket 101 offset by γ1 angle. The dashed part in the figure represents the initial position of the bracket 101, and the solid part represents the position of the bracket 101 after it makes a leftward thrust. When adjusting the illumination angle of the light source 102 in the horizontal direction, the second adjustment component 30 is operated to push the bracket 101 to rotate around the dimming axis III. The light source 102 rotates together with the bracket 101. The light source 102 changes from the initial illumination along the parallel direction to illumination offset to the right by γ1 angle in the horizontal direction.

[0091] The horizontal deflection adjustment modes include a right deflection adjustment mode, with the straight axis passing through the center of the second adjustment component 30 along the Y direction as the dimming axis IV. Figure 10 The diagram illustrates the dimming axis “Ⅳ” (the direction of “Ⅳ” is perpendicular to the paper surface). The first and third adjustment components are driven synchronously to retract the support 101 in the reverse direction along the Z direction, with a retraction angle of γ2.

[0092] Specifically, Figure 10 C2 is a schematic diagram of the forward tilt angle γ2 of the bracket 101. The dashed line in the diagram represents the initial position of the bracket 101, and the solid line represents the position of the bracket 101 after its retraction action. When adjusting the illumination angle of the light source 102 in the horizontal direction, the first and third adjustment components retract in opposite directions along the Z direction to drive the bracket 101 to rotate around the dimming axis IV. Figure 10 C2 is a further rotation based on C1, with a rotation angle of γ2. The light source 102 rotates together with the bracket 101, and the light source 102 is offset to the right by an angle of γ2 in the horizontal direction.

[0093] In general, refer to Figure 10 In C3, the sum of γ1 and γ2 is the rightward deflection angle γ of the bracket 101. When the bracket 101 deflects to the right by γ in the horizontal direction, the light source 102 also shifts to the right by γ, and the illumination angle of the light source 102 also shifts to the right by γ, thereby realizing the adjustment of the illumination angle in the horizontal direction.

[0094] In addition, the above Figure 10 The C1 to C2 and C2 to C3 sequences are just one possible adjustment sequence in the right-angle adjustment mode. In actual lamp adjustment, it is also possible to adjust only one angle, γ1 or γ2, or to adjust angle γ2 first and then angle γ1. Referring to the right-angle adjustment process of C1 to C2 and C2 to C3 described above, other adjustment sequences will not be elaborated in detail.

[0095] Reference Figure 11 The horizontal adjustment mode also includes a left-tilt adjustment mode, which uses the straight axis passing through the centers of the first and third adjustment components along the Y direction as the dimming axis III. Figure 11The upper right corner shows the dimming axis “Ⅲ” (the direction of “Ⅲ” is perpendicular to the paper). The second adjustment component 30 drives the bracket 101 to retract along the Z direction. The deflection angle of the bracket 101 during retraction is δ1.

[0096] Specifically, Figure 11 D1 is a schematic diagram of the bracket 101 tilting forward at an angle δ1. The dashed part in the figure represents the initial position of the bracket 101, and the solid part represents the position of the bracket 101 after it shifts to the left. When adjusting the illumination angle of the light source 102 in the horizontal direction, the second adjustment component 30 pushes the bracket 101 to rotate around the dimming axis III. The light source 102 rotates together with the bracket 101. The light source 102 changes from initially illuminating in the parallel direction to illuminating in the horizontal direction at an angle δ1 to the left.

[0097] Reference Figure 11 The left-bias adjustment mode also includes: using a linear axis passing through the center of the second adjustment component 30 along the Y direction as the dimming axis IV. Figure 11 The diagram shows the dimming axis “Ⅳ” (the direction of “Ⅳ” is perpendicular to the paper surface). The first and third adjustment components are driven synchronously to drive the bracket 101 to extend along the Z direction, with an extension angle of δ2.

[0098] Specifically, Figure 11 Figure D2 shows a schematic diagram of the bracket 101 deflecting to the left by an angle δ2. The dashed line represents the initial position of the bracket 101, and the solid line represents the position of the bracket 101 after the leftward deflection. When adjusting the illumination angle of the light source 102 in the horizontal direction, the first and third adjustment components are synchronously driven to extend along the Z direction to drive the bracket 101 to rotate around the dimming axis IV. Figure 11 D2 is a further rotation based on D1, with a rotation angle of δ2. The light source 102 deflects to the left along with the bracket 101, and the light source 102 is deflected to the left by an angle of δ2 in the horizontal direction.

[0099] In general, refer to Figure 11 In D3, the sum of δ1 and δ2 is the leftward tilt angle δ of the bracket 101. With a leftward tilt δ in the horizontal direction, the light source 102 also shifts to the left by δ, and the illumination angle of the light source 102 shifts to the left by δ, thereby realizing the adjustment of the illumination angle in the horizontal direction.

[0100] In addition, the above Figure 11 The D1 to D2 and D2 to D3 adjustments are just one possible sequence in the left-tilt adjustment mode. In actual lighting adjustments, it's also possible to adjust only one angle, δ1 or δ2, or to adjust δ2 first and then δ1. Referring to the backward tilt adjustment process described above for B1 to B2 and B2 to B3, other adjustment sequences will not be elaborated upon further.

[0101] It should be noted that the various angle adjustments in the above-mentioned pitch angle adjustment modes are not isolated, but rather, according to user needs, the various adjustment methods are mutually constitutive means of changing the direction of the light source 102. For example, the bracket 101, as... Figure 8 In mode A1, a forward tilting motion was performed, at which point the light source 102 was offset downwards. If the user needs the light source 102 to be illuminated parallel to the user in the next step, then a backward tilting motion needs to be applied to the bracket 101. Using the linear axis passing through the center of the third adjustment component 40 along the X direction as the dimming axis I, the first and second adjustment components retract synchronously in opposite directions along the Z direction to drive the bracket 101 to tilt backwards. Figure 9 The backward tilting motion of B1 adjusts the light emission direction of the light source 102 to illuminate in a parallel direction.

[0102] In addition, the dimming axis V can be taken as the straight axis connecting the axis of the second adjustment component 30 and the axis of the third adjustment component 40. When the first adjustment component 20 extends and retracts along the Z direction, the bracket 101 rotates along the dimming axis V. Since the dimming axis V is inclined to the X-axis in the XY plane, the bracket 101 deflects at a certain angle in the horizontal direction and at a certain angle in the vertical direction, thereby changing the illumination angle of the light source 102 in space.

[0103] In some embodiments, refer to Figure 4 , Figure 5 and Figure 6 Along the X direction, the bracket 101 is provided with two mounting holes 1011, and the first adjustment component 20 and the second adjustment component 30 are respectively connected to one mounting hole 1011.

[0104] Specifically, one end of the first and second adjustment components (usually via screws, clips, etc.) is rigidly connected to the mounting hole 1011. This connection point serves as a positioning and primary support, defining a reference position for the adjustment components in space.

[0105] Reference Figure 4 , Figure 5 and Figure 6 Along the Y direction, the first adjusting component 20 has a gap 1012 between it and the two side walls of the mounting hole 1011; along the X direction, the second adjusting component 30 has a gap 1012 between it and the two side walls of the mounting hole 1011.

[0106] Specifically, in the Y direction, a gap 1012 is intentionally left between the adjustment component and the side wall of the mounting hole 1011. When the bracket 101 rotates, this gap 1012 serves as a reserved space for the adjustment component to move. This reserved space provides the first adjustment component 20 with the degree of freedom to offset in the bracket 101, allowing the first adjustment component 20 to rotate relative to the bracket 101. This allows the bracket 101 to deflect in the vertical Y direction, so that the light source 102 can rotate with the bracket 101 and change the illumination angle of the light source 102, ultimately achieving dimming.

[0107] Similarly, along the X direction, the second adjustment component 30 and the two side walls of the mounting hole 1011 are provided with a gap 1012, so that the second adjustment component 30 can rotate relative to the bracket 101, thereby allowing the bracket 101 to deflect in the horizontal X direction.

[0108] In this embodiment, the gaps between the first adjustment component 20, the second adjustment component 30 and the mounting hole are respectively located on both sides of the mounting hole along the Y direction and on both sides along the X direction, that is, adjustment gaps are reserved in both the X and Y directions at the same time, so that the device has a large degree of freedom of offset in the entire XY plane; and the design and construction of the reserved gap in this embodiment is simple enough and can also ensure the stability of the rotational connection.

[0109] In other embodiments, gaps 1012 may be provided between the two sides of the first adjusting component 20 and the two side walls of the mounting hole 1011 along the X direction; and gaps 1012 may be provided between the second adjusting component 30 and the two side walls of the mounting hole 1011 along the Y direction.

[0110] In other embodiments, gaps 1012 may be provided between the two sides of the first adjusting component 20 and the mounting hole 1011 along the X direction, and gaps 1012 may be provided between the second adjusting component 30 and the two side walls of the mounting hole 1011 along the X direction. In other embodiments, gaps 1012 may be provided between the two sides of the first adjusting component 20 and the mounting hole 1011 along the Y direction, and gaps 1012 may be provided between the second adjusting component 30 and the two side walls of the mounting hole 1011 along the Y direction.

[0111] It should be noted that the gap 1012 between the first and second adjustment components and the side wall of the mounting hole 1011 is only a preferred case, which can allow the bracket to have a larger deflection angle. When there is no gap between the first and second adjustment components and the side wall of the mounting hole 1011, the first and second adjustment components can also be rotatably connected to the bracket 101, so that the bracket 101 can also deflect in the X and Y directions. In this case, the deflection angle of the bracket 101 in the X and Y directions is smaller.

[0112] In some embodiments, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The first and second adjustment components include: an adjustment nut 201, which is installed in the mounting hole 1011; an adjustment rod 202 threadedly connected to the adjustment nut 201, which extends toward the side away from the bracket 101 in the Z direction; and a rotary adjustment member 203 connected to the end of the adjustment rod 202 away from the adjustment nut 201, which is configured to drive the adjustment rod 202 to rotate about its own axis to drive the bracket 101 to offset in the Z direction.

[0113] Specifically, the adjusting nut 201 is fixed to the mounting hole 1011 of the bracket 101. It has internal threads or is connected via a self-tapping thread through the adjusting rod 202. The adjusting rod 202 is threaded into the adjusting nut 201, allowing it to rotate within the nut. Since the adjusting nut 201 itself cannot rotate, the rotation of the adjusting rod generates an axial (Z-direction) thrust, pushing the bracket 101 to extend or pull it to retract. The rotating adjustment element 203 is connected to the end of the adjusting rod 202, serving as the user's operating end. It is typically a geared lever connected to the adjusting rod 202 via gears. During dimming, moving the lever rotates the adjusting rod 202, applying an axial (Z-direction) force to the bracket 101, pushing it to extend or pull it to retract. The light source 102 rotates with the bracket 101, changing its illumination angle and ultimately achieving dimming.

[0114] In some embodiments, refer to Figure 3 The third adjustment component 40 includes a ball-head nut 401 and a telescopic motor 402. The ball-head nut 401 is installed on the side of the bracket 101 away from the main light emission direction of the light source 102. The telescopic motor 402 includes a ball-head end 4021, which is connected to the ball-head nut 401.

[0115] Specifically, the ball-end nut 401 is essentially the inner ring of a spherical bearing, with a spherical surface inside. The telescopic motor 402 is a linear motor, and its output end is a ball-end 4021, i.e., a spherical end. The ball-end 4021 of the telescopic motor 402 is embedded in the ball-end nut 401, forming a ball joint connection, which allows for multi-directional swinging. When the telescopic motor 402 extends or retracts, using the linear axis containing the centers of the first and second adjusting components as the pivot, this ball joint connection is pushed or pulled by the motor push rod. When the push rod moves linearly, it causes the bracket 101 to tilt around the pivot axis. The tilting of the bracket 101 changes the illumination angle of the light source 102, thereby changing the direction of the light beam, i.e., adjusting the angle or position of the illumination.

[0116] In some embodiments, refer to Figure 1 , Figure 2, Figure 7 and Figure 12 The lamp adjustment mechanism also includes: a housing 50, which is slidably connected to the bracket 101 on the side away from the main light output direction of the light source 102; along the Z direction, the first and second adjustment components pass through the housing 50 and are connected to the bracket 101; and two fixing members 60, which are located on the same straight line as the ball end 4021 along the x direction, and the two fixing members 60 are located on both sides of the ball end 4021 respectively.

[0117] Specifically, when the telescopic motor 402 pulls its ball end 4021, the telescopic motor 402 applies a force opposite to the Z-direction to the bracket 101. Since forces are mutual, the bracket 101 exerts a Z-direction force on the ball end 4021, causing the telescopic motor 402 to tend to move in the Z-direction. Because the telescopic motor 402 is also mounted to the housing 50 via the fixing member 60, the housing 50 applies a force opposite to the Z-direction to the telescopic motor 402 via the fixing member 60. In the above situation, if the fixing member 60 and the ball end 4021 are not on the same straight line, the force on the telescopic motor 402 will also not be in the same plane, causing the telescopic motor 402 to rotate about the line connecting the two fixing members 60, resulting in the telescopic motor 402 wobbling.

[0118] In this application, the fixing member 60 and the ball end 4021 are located on the same straight line, and the two fixing members 60 are located on both sides of the ball end 4021 respectively. The force acting on the telescopic motor 402 is in the same plane, that is, the force along the Z direction and the force in the opposite direction along the Z direction cancel each other out, ensuring the stability of the telescopic motor 402.

[0119] The fastener 60 can be a bolt, a cylindrical pin, etc., which forms a fixed connection with the corresponding hole / slot on the bracket 101.

[0120] In some embodiments, refer to Figure 2 , Figure 3 and Figure 12 The telescopic motor 402 includes a body 4022 connected to the housing 50; the side of the body 4022 away from the housing 50 is connected to a ball end 4021, and the body 4022 is rectangular; the housing 50 is provided with a through hole 501 corresponding to the light source 102, the through hole 501 is configured to allow a cable to pass through to connect to the light source 102, and the long side of the body 4022 is tangent to the through hole 501.

[0121] Specifically, the luminaire requires external cables to power and communicate with the light source 102, and the cables need to pass through the through hole 501 to connect to the light source 102. In addition, placing the long side of the rectangular motor body 4022 tangent to the edge of the circular through hole 501, compared to placing it randomly or with the short side of the telescopic motor 402 facing the through hole 501, can minimize the space occupied by the telescopic motor 402 in the X and Y directions on the surface of the housing 50, maximize space utilization, achieve a compact structure, and thus make the entire luminaire more compact.

[0122] Furthermore, since the long side of the motor body 4022 is tangent to the edge of the circular through hole 501, it is clear that the telescopic motor 402 and the through hole 501 will not overlap. Therefore, there will be no accidental contact or interference between the live cable and the motor body 4022, which meets the electrical safety specifications.
