[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0035] Embodiment 1

[0036] Refer to Figure 1 , this utility model discloses a color wheel adjustment assembly, which includes a color wheel 1, a driving assembly, and a position detection assembly. Refer to Figure 2 , the driving assembly includes a motor 5, a first transmission member, and a second transmission member. Specifically, the second transmission member is in transmission connection with the first transmission member, and the color wheel 1 is connected to the second transmission member; wherein, the motor 5 is used to drive the first transmission member to rotate, and the second transmission member is used to transmit when the first transmission member rotates and guide the color wheel 1 to move linearly.

[0037] In addition, the position detection assembly includes a detection member and a sensor 3, and the detection member is connected to the color wheel 1 or the second transmission member; wherein, the detection member is used to detect the position of the color wheel 1, and the sensor 3 is electrically connected to the detection member.

[0038] It should be noted that the color wheel adjustment assembly of this utility model is used to adjust the position of the color wheel 1 in a plane perpendicular to the optical axis of the laser light source 9. Specifically, as Figure 5 shown, the color wheel 1 and the laser light source 9 are arranged at intervals in the Y-axis direction. At this time, the Y-axis direction is the extending direction of the optical axis of the laser light source 9; then the plane where the X-axis is located is the plane perpendicular to the optical axis of the laser light source 9, and the X-axis direction is perpendicular to the Y-axis direction. And the relative height of the color wheel 1 and the laser light source 9 of this utility model remains unchanged, so the color wheel adjustment assembly can be used to adjust the relative position of the color wheel 1 and the laser light source 9 in the X-axis direction.

[0039] On the basis of this structure, when using the color wheel adjustment assembly of this utility model, the driving assembly can drive the first transmission member and the second transmission member to transmit according to the different powers of the laser light source 9 through the motor 5, so as to drive the color wheel 1 to move in the X-axis direction. Specifically, a plurality of color temperature compensation areas 13 are provided on the color wheel 1, and the plurality of color temperature compensation areas 13 are arranged radially along the color wheel 1; when the driving assembly drives the color wheel 1 to move to the corresponding position in the X-axis direction according to the power of the laser light source 9, the optical axis of the laser light source 9 can pass through the corresponding color temperature compensation area 13 on the color wheel 1, so as to obtain the corresponding color temperature compensation in the case of this power segment.

[0040] It should be noted that due to different temperatures at different power levels, the laser light source 9 will exhibit different degrees of color temperature drift, resulting in a decline in the lighting effect. The present utility model utilizes the color wheel 1 to perform color temperature compensation on the laser light source 9, which can adjust the color of the light emitted by the light source to make it closer to the color temperature value of the original design. Moreover, the color wheel adjustment assembly can adjust the relative position of the color wheel 1 and the laser light source 9 on the X-axis according to different power segments of the laser light source 9, so that the laser light source 9 irradiates different color temperature compensation areas 13 on the color wheel 1, thereby meeting the color temperature compensation requirements under various power segments and ensuring that the laser light source 9 can provide a stable color temperature output at different powers.

[0041] Among them, the color wheel 1 is a rotating device, usually including a wheel disc, and multiple filter films of different colors or phosphors coated with different colors are provided on the wheel disc. The areas where these filter films or phosphors are located form different color temperature compensation areas 13. By selecting appropriate color combinations, the filter films or phosphors can adjust the color temperature of the light emitted by the laser light source 9.

[0042] Specifically, referring to Figure 4 , when the laser light source 9 passes through the color temperature compensation area 13 on the color wheel 1, the filter film or phosphor will interact with the laser beam. Such an interaction process will cause part of the color of the beam to be absorbed by the filter film, while the other part of the color is transmitted; or the energy of the laser is absorbed by the phosphor and emits radiation. In this way, the laser light source 9 can adjust the color temperature of the light it emits to a certain extent through the color wheel 1, achieving the effect of color temperature compensation. This has great practical value for occasions that require a consistent color temperature output in different environments, such as stage lighting, film and television shooting, etc.

[0043] It is worth noting that the present utility model can achieve origin positioning through the position detection component, thereby eliminating the cumulative position error during the process of the color wheel adjustment component adjusting the position of the color wheel 1. Specifically, the detector can position the position of the color wheel 1. After the detector triggers the inductor 3, the inductor 3 can output the current position signal of the color wheel 1 to the drive component. Subsequently, the drive component can drive the color wheel 1 to move a corresponding distance from the origin to the corresponding position according to the power segment of the laser light source 9. Since the color wheel 1 starts moving from the origin, the previously accumulated movement errors are all eliminated, making the position adjustment of the color wheel 1 more accurate. That is to say, through the position detection component, the cumulative error after multiple adjustments of the color wheel adjustment component can be eliminated, improving the accuracy of the position adjustment of the color wheel 1, and thus realizing color temperature compensation for the laser light source 9 in the corresponding power segments.

[0044] Furthermore, the color wheel adjustment assembly includes a bracket 4, referring to Figure 1, the motor 5 is connected to the bracket 4, and a driven shaft 41 is also provided on the bracket 4. Among them, the first transmission member is a synchronous belt 6, and the synchronous belt 6 is arranged around the output shaft 51 of the motor 5 and the driven shaft 41.

[0045] On this structural basis, the output shaft 51 and the driven shaft 41 are arranged at intervals, so that after the synchronous belt 6 is connected to the output shaft 51 and the driven shaft 41, the synchronous belt 6 is in a tensioned state. When in use, the motor 5 starts to rotate the output shaft 51, and the output shaft 51 drives the synchronous belt 6 to rotate through friction, and then the synchronous belt 6 drives the driven shaft 41 to rotate through friction.

[0046] Among them, the part of the synchronous belt 6 located between the output shaft 51 and the driven shaft 41 moves linearly. Thus, the synchronous belt 6 can convert the circular motion of the output shaft 51 of the motor 5 into a linear motion, thereby guiding the color wheel 1 to displace in the X-axis direction.

[0047] It should be noted that the first transmission member can also be a transmission screw, and the second transmission member is a nut, and the nut is screwed on the transmission screw, and the nut is linked with the color wheel 1. When the motor 5 drives the transmission screw to rotate through the output shaft 51, the nut can move linearly along the axial direction of the screw. Through the combination of the screw and the nut, the circular motion of the output shaft 51 of the motor 5 can be converted into a linear motion to drive the color wheel 1 to move linearly.

[0048] In addition, the first transmission member can also be a gear, and the second transmission member is a rack. Among them, the gear is connected to the output shaft 51 of the motor 5, the color wheel 1 is connected to one end of the rack, and the gear is meshed with the rack. When the motor 5 drives the gear to rotate through the output shaft 51, the gear can drive the rack to move linearly, and then the rack can drive the color wheel 1 to move linearly.

[0049] Furthermore, referring to Figure 2 , the second transmission member includes a connecting block 7 and a moving block 8. Among them, the connecting block 7 is limit-connected to the synchronous belt 6, and the moving block 8 is fixedly connected to the connecting block 7.

[0050] On this structural basis, during assembly, the connecting block 7 can be limit-connected to the synchronous belt 6 through fasteners such as screws and bolts; in addition, the moving block 8 is arranged at an interval from the synchronous belt 6, and the moving block 8 is fixedly connected to the connecting block 7 through fasteners such as bolts.

[0051] Among them, the limit connection between the connecting block 7 and the synchronous belt 6 can prevent the problem that the position adjustment of the color wheel 1 is inaccurate due to slipping between the connecting block 7 and the synchronous belt 6. In addition, the connecting block 7 can drive the moving block 8 to move linearly together, and since the moving block 8 is arranged at an interval from the synchronous belt 6, the moving block 8 will not generate resistance to the movement of the synchronous belt 6, which is beneficial to the smooth transmission of the synchronous belt 6.

[0052] Further, referring to Figure 3 , the timing belt 6 has a first transmission section and a second transmission section. Specifically, the first transmission section is an arc section, and the first transmission section is connected to the output shaft 51 and the driven shaft 41; the second transmission section is a straight section, and the connecting block 7 is connected to the second transmission section.

[0053] Specifically, the timing belt 6 has two first transmission sections and two second transmission sections, and the two first transmission sections are respectively connected to the output shaft 51 and the driven shaft 41, and the two second transmission sections are arranged vertically up and down. Among them, the connecting block 7 is arranged on the upper surface of the lower second transmission section, and the moving block 8 is arranged below the second transmission section.

[0054] During use, when the motor 5 rotates in one direction, it can drive the arc section of the timing belt 6 to rotate in that direction, so that the straight section of the timing belt 6 moves along one side of the X-axis, and then drives the connecting block 7 to move along one side of the X-axis; when the motor 5 rotates in the opposite direction, it can drive the arc section of the timing belt 6 to rotate in the opposite direction, so that the straight section of the timing belt 6 moves along the other side of the X-axis, and then drives the connecting block 7 to move along the other side of the X-axis, thereby being able to adjust the relative position of the color wheel 1 and the laser light source 9 on the X-axis.

[0055] Among them, the connecting block 7 is arranged between the upper and lower second transmission sections, which can make full use of the space of the timing belt 6 and make the connection between the transmission parts compact.

[0056] Further, referring to Figure 5 , transmission gears are connected to both the output shaft 51 and the driven shaft 41; among them, the timing belt 6 is provided with first connecting teeth 61, and the first connecting teeth 61 are meshed with the transmission gears.

[0057] Specifically, the timing belt 6 is meshed with the tooth structure on the transmission gear through the first connecting teeth 61. When the output shaft 51 rotates, it can drive the transmission gear to rotate. During the rotation of the transmission gear, it drives the timing belt 6 to rotate through the meshing structure. Further, during the rotation of the timing belt 6, it drives the second transmission part and the color wheel 1 to do linear motion through the second transmission section.

[0058] Thus, the meshing connection of the tooth structure is adopted between the output shaft 51 of the motor 5 and the timing belt 6, which can prevent the timing belt 6 from slipping with the output shaft 51, ensure that the timing belt 6 can generate the correct path under the control of the motor 5, thereby driving the color wheel 1 to the accurate position and reducing the position error of the color wheel 1.

[0059] Further, the connecting block 7 is provided with second connecting teeth 71, and the second connecting teeth 71 are meshed with the first connecting teeth 61 to make the connecting block 7 move synchronously with the timing belt 6.

[0060] Thus, the output shaft 51 of the motor 5 is meshed and connected with the synchronous belt 6, and the connecting block 7 and the synchronous belt 6 are meshed and connected through the first connecting teeth 61 and the second connecting teeth 71, which can greatly reduce the slipping phenomenon during the belt transmission, ensure that the synchronous belt 6 can travel the correct distance under the control of the motor 5, and further ensure the accuracy of the position adjustment of the color wheel 1 by the color wheel adjustment assembly, while obtaining a more stable power transmission.

[0061] Further, the moving block 8 includes a mounting section 81 and a connecting section 82. Specifically, the mounting section 81 extends in the vertical direction, the connecting section 82 is connected to the upper end of the mounting section 81, and the connecting section 82 extends in the horizontal direction; wherein, the mounting section 81 is connected to one side of the color wheel 1, and the connecting section 82 is connected to the connecting block 7.

[0062] On this structural basis, the color wheel 1 further includes a color wheel bracket 11, and the turntable 12 of the color wheel 1 is rotatably connected to the color wheel bracket 11 through a rotating shaft. During assembly, the side of the color wheel 1 away from the light source is fixedly connected to the mounting section 81 of the moving block 8 through the color wheel bracket 11; the connecting section 82 of the moving block 8 is connected to the bottom of the connecting block 7 through fasteners such as screws and bolts.

[0063] Thus, the moving block 8 obtains power input through the connection of the connecting section 82 at the upper end to the connecting block 7, and realizes power output through the connection of the mounting section 81 to the color wheel 1. The moving block 8 has a large connection area with both the connecting block 7 and the color wheel 1, thus ensuring the stability during the power transmission process. In addition, by arranging the moving block 8 and the connecting block 7 in the vertical direction and realizing the synchronous movement of the color wheel 1 and the synchronous belt 6 in the horizontal direction, the overall assembly of the color wheel adjustment component is compact and the structure is stable.

[0064] Further, a support member 42 is provided on the support member 42, and the support member 42 abuts against the bottom of the mounting section 81.

[0065] Specifically, the support member 42 can be a support column, a support plate, etc., and its two ends are fixedly connected to the bracket 4 through fasteners such as screws. When the second transmission member is transmitting power, the moving block 8 abuts against the upper side of the support member 42 through the bottom of the mounting section 81. The support member 42 can support and guide the moving block 8, so that the color wheel 1 and the moving block 8 move stably under the drive of the connecting block 7 without deviation, ensuring smooth and stable movement during the position adjustment of the color wheel 1.

[0066] Further, the position detection component is a contact sensor. Specifically, the detection piece is the detection piece 2, and the detection piece 2 is connected to the moving block 8; the inductor 3 is connected to the bracket 4, and the inductor 3 is used to be touched by the detection piece 2 and output an electrical signal.

[0067] Based on this structure, the detection piece 2 and the inductor 3 can be respectively connected to the moving block 8 and the bracket 4 through fasteners such as bolts. During use, the detection piece 2 can receive the position signal of the color wheel 1 and output an electrical signal. The inductor 3 can receive the electrical signal of the detection piece 2 when touched by the detection piece 2 and output a control signal to the motor 5.

[0068] Among them, the contact sensor can specifically be a travel switch sensor or a pressure sensor. When the moving block 8 drives the detection piece 2 during movement, causing the detection piece 2 to touch the inductor 3, the switch can be triggered.

[0069] In this way, the inductor 3 can be used as the origin position. When the detection piece 2 moves to touch the inductor 3, the switch signal can be triggered, causing the inductor 3 to output a control signal to the motor 5. The motor 5 can move the color wheel 1 a corresponding distance from the origin position to the corresponding position according to the current power segment of the laser light source 9 through the transmission member, so that the optical axis of the laser light source 9 can pass through the color temperature compensation area 13 corresponding to this power segment. Since the color wheel 1 starts to move from the origin position, the previous position cumulative error is eliminated, and accurate adjustment of the position of the color wheel 1 can be achieved.

[0070] In addition, the position detection component can also be a proximity sensor, specifically an optoelectronic proximity switch or an electromagnetic proximity switch, etc. When the detection piece (such as the detection piece 2, the detection block, etc.) approaches the set distance of the inductor 3, the switch signal can be triggered.

[0073] When using the lighting device of the present utility model, the color wheel adjustment component can adjust the relative position of the color wheel 1 and the laser light source 9 in the X-axis direction according to different powers of the laser light source 9, so that the optical axis of the laser light source 9 can pass through the corresponding color temperature compensation area 13 on the color wheel 1, thereby obtaining the corresponding color temperature compensation in the case of this power segment, and solving the problem that the laser light source 9 will have different degrees of color temperature drift due to different temperatures under different power conditions, resulting in a decrease in the lighting effect.

[0074] Among them, the specific structure of the color wheel adjustment component and the adjustment process of the color wheel 1 are described in detail in Embodiment 1, and will not be elaborated here too much.

[0075] In summary, in the lighting device of the present utility model, the laser light source 9 can obtain corresponding color temperature compensation at different power levels, which can ensure the consistency of color temperature, making the color of the light emitted by the lighting device closer to the color temperature value of the original design and having a better lighting effect.
