[0045] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] See also Figure 1-Figure 3As shown, the present invention discloses a lighting fixture 100, comprising a housing 200, a heat dissipation module 300, a light source module 400, an optical integration module 500, and a power supply module 600 assembled within the housing 200. The housing 200 is arranged to extend vertically, and the heat dissipation module 300 is assembled at the first end 201 of the housing 200. The light source module 400 is connected to the heat dissipation module 300 and assembled on the side of the heat dissipation module 300 facing away from the first end 201. The optical integration module 500 is connected to the heat dissipation module 300 and is located below the light source module 400 in the axial direction of the housing 200, that is, in the light emitting direction of the light source module 400. The optical integration module 500 is used to adjust the light emitted by the light source module 400.

[0047] In this embodiment, the light source module 400 and the power supply module 600 are connected to the intelligent driver of the lamp through a conductive wire to enable the light source module 400 and the power supply module 600 to be powered. The heat dissipation module 300 is provided with a threading hole (not shown) for the conductive wire to pass through, and the threading holes are preferably two. The light source module 400 includes a light source bracket 401 and a light source (unnumbered) mounted on the light source bracket 401, and the light source bracket 401 is connected to the heat dissipation module 300. In the axial direction of the housing 200, the power supply module 600 is located between the light source module 400 and the optical integration module 500.

[0048] Combine Figure 4 As shown, the power supply module 600 includes a circuit board 601 and a plurality of pins 602 integrated on the circuit board 601 and extending toward the optical integration module 500. The circuit board 601 is electrically connected to the intelligent driver of the lamp. The power supply module 600 also includes a support frame 603 for mounting the circuit board 601. The support frame 603 is arranged around the periphery of the light source module 400 and abuts against the light source module 400. A plurality of pins 602 pass through the support frame 603 and extend into the optical integration module 500, connecting the power supply module 600 and the optical integration module 500 to provide power to the optical integration module 500.

[0049] Specifically, the circuit board 601 protrudes from the outer wall of the support frame 603, and the support frame 603 is also provided with a fixing column 604 extending toward the optical integration module 500 for a plurality of pins 602 to pass through, and the fixing column 604 abuts against the optical integration module 500. The support frame 603 abuts against the light source bracket 401. The outer periphery of one end of the support frame 603 close to the light source bracket 401 is provided with a connecting portion 605 for connecting to the heat dissipation module 300, and the connecting portion 605 is provided with multiple and is arranged around the outside of the light source bracket 401. The connecting portion 605 is provided with a connecting hole 6051 for a fastener (not shown) to pass through, so that the support frame 603 can be fixedly connected to the heat dissipation module 300 by the fastener. At the same time, on the basis of keeping the position of the support frame 603 fixed, the heat generated by the power supply module 600 can also be dissipated through the heat dissipation module 300. The end of the support frame 603 away from the light source module 400 is connected to the optical integration module 500.

[0050] Combine Figure 5 and Figure 6 As shown, the optical integration module 500 is an annular structure, including an outer frame 501, a driving mechanism 502 assembled in the outer frame 501, a focusing component 503 and a polarization steering component 504. The outer frame 501 is arranged to pass through from top to bottom, and the outer frame 501 is coaxially arranged with the outer shell 200. A plurality of pins 602 extend into the driving mechanism 502 to supply power to the driving mechanism 502. The driving mechanism 502 can drive the focusing component 503 to move back and forth along the axial direction of the outer frame 501 to achieve the focusing function. The driving mechanism 502 can also drive the polarization steering component 504 to rotate around the axial direction of the outer frame 501 to achieve the polarization and steering functions. The optical integration module 500 of the present invention integrates the light focusing function, light deflection and steering functions, and realizes functional adjustment through electric control, which has better stability.

[0051] Combine Figure 7 and Figure 8 As shown, the driving mechanism 502 includes a first driving mechanism 11 and a second driving mechanism 12, and the polarization steering assembly 504 can rotate around the axial direction of the outer frame 501 under the driving action of the second driving mechanism 12. The focusing assembly 503 can move back and forth along the axial direction of the outer frame 501 under the driving action of the first driving mechanism 11. The driving mechanism 502 also includes an adapter plate 13, which is arranged on the outer peripheral wall of the support frame 603. The adapter plate 13 is provided with a plurality of contacts (not shown) to electrically contact with a plurality of pins 602. The first driving mechanism 11 and the second driving mechanism 12 are electrically connected to the power supply module 600 through the plurality of pins 602 and the plurality of contacts, so that the first driving mechanism 11 and the second driving mechanism 12 are powered. The utility model connects the driving mechanism 502 inside the optical integrated module 500 with the adapter plate 13, so that the entire optical integrated module 500 has a unified and integrated input port, which is convenient for free disassembly and replacement of each module.

[0052] The drive mechanism 502 also includes a mounting bracket 14 for mounting the first drive mechanism 11 and the second drive mechanism 12. The mounting bracket 14 is fixed to the inner peripheral wall of the outer frame 501. Specifically, the mounting bracket 14 includes a mounting surface 141 perpendicular to the inner peripheral wall of the outer frame 501 and a fixing surface 142 arranged to fit the inner peripheral wall of the outer frame 501. The first drive mechanism 11 and the second drive mechanism 12 are mounted on the mounting surface 141, and the fixing surface 142 is engaged with the end of the outer frame 501 facing the heat dissipation module 300. The mounting bracket 14 is also fixed to the outer frame 501 by providing a fastener (not shown) that passes through the side wall of the outer frame 501 and is connected to the fixing surface 142. A through hole 143 is provided at the center of the mounting bracket 14, that is, a through hole 143 is provided at the center of the mounting surface 141, and the focusing assembly 503 partially extends into the interior of the mounting bracket 14 from the through hole 143.

[0053] Combine Figures 9-11 As shown, the first drive mechanism 11 includes a third motor 112 and a third transmission gear 111 mounted on the third motor output shaft 110. The focusing assembly 503 includes a focusing gear 21 meshing with the third transmission gear 111. Upon activation of the third motor 112, the focusing assembly 503 reciprocates axially along the outer frame 501, driven by the focusing gear 21 and the third transmission gear 111. The third motor output shaft 110 extends beyond the mounting frame 14, and the third transmission gear 111 is located outside the mounting frame 14. The focusing gear 21 is located outside the mounting frame 14, and the third motor 112 is disposed outside the focusing gear 21.

[0054] Specifically, the focusing assembly 503 includes a first focusing lens 22 and a second focusing lens 24 located below the light source module 400 in the axial direction of the housing 200. An upper cover 23 for fixing the first focusing lens 22 is provided on the periphery of the first focusing lens 22. The upper cover 23 is connected to the mounting frame 14, and a receiving space 230 is formed between the upper cover 23 and the mounting frame 14. The first drive mechanism 11 and the second drive mechanism 12 are both partially received in the receiving space 230. Preferably, the upper cover 23 and the mounting frame 14 are also fixedly connected by fasteners (not shown). The first drive mechanism 11 and the second drive mechanism 12 are upright in the receiving space 230, and their two ends are connected to the mounting frame 14 and the upper cover 23 respectively. Preferably, the first drive mechanism 11 and the second drive mechanism 12 partially extend out of the upper cover 23 to limit the first drive mechanism 11 and the second drive mechanism 12 in the receiving space 230. The adapter plate 13 is located within the receiving space 230 and mounted on the side of the upper cover 23 facing the first and second drive mechanisms 11 and 12. The upper cover 23 defines a socket 231, through which the adapter plate 13 is partially exposed. Multiple pins 602 are inserted into the socket 231 and abut against multiple contacts on the adapter plate 13. The adapter plate 13 is preferably located on the side of the upper cover 23 opposite the mounting surface 141. The multiple pins 602 are resilient, ensuring a secure connection between them and the adapter plate 13. The fixing posts 604 abut the upper cover 23 and are supported on the periphery of the socket 231.

[0055] In this embodiment, the support frame 603 extends into and abuts the upper cover 23. The support frame 603 is located above the first focusing lens 22. Guide ribs 606 are provided on the outer circumference of the support frame 603, and guide grooves 232 are provided on the inner circumference of the upper cover 23, corresponding to the guide ribs 606. The support frame 603 extends into the upper cover 23, the guide ribs 606 are inserted into the guide grooves 232, and the multiple pins 602 are inserted into the corresponding receptacles 231. When the guide ribs 606 engage the corresponding guide grooves 232, the multiple pins 602 abut their corresponding contacts. The cooperation between the guide ribs 606 and the guide grooves 232 facilitates assembly. Of course, in other alternative embodiments, guide grooves 232 may be provided on the support frame 603, and guide ribs 606 may be provided on the inner circumference of the upper cover 23. This is not a limitation as long as it facilitates assembly.

[0056] The first focusing lens 22 and the second focusing lens 24 are configured to rotate relative to each other to change the distance between them to achieve focusing. It should be understood that the first focusing lens 22 and the second focusing lens 24 may be configured such that one of the first focusing lens 22 and the second focusing lens 24 is fixed while the other rotates relative to the first focusing lens 22, or both rotate in the same direction but at different speeds, or both rotate in different directions to achieve the purpose of changing the distance between them. This utility model is described in detail using the example of the first focusing lens 22 being fixed while the second focusing lens 24 rotates, but the invention is not limited thereto.

[0057] In the axial direction of the outer frame 501, the second focusing lens 24 is located below the first focusing lens 22. The outer periphery of the second focusing lens 24 is provided with a fixing frame 25 for fixing the second focusing lens 24 and a rotating ring 26 arranged on the outside of the fixing frame 25 and connected to the fixing frame 25. The rotating ring 26 and the outer frame 501 can rotate relative to each other. Specifically, the rotating ring 26 is connected to the upper cover 23 and can rotate relative to the upper cover 23. In this embodiment, the first focusing lens 22 is fixedly connected to the upper cover 23, and both the first focusing lens 22 and the upper cover 23 are fixed. The second focusing lens 24 is fixedly connected to the rotating ring 26, and the second focusing lens 24 is transmission-connected to the first driving mechanism 11, and can approach or move away from the first focusing lens 22 under the driving action of the first driving mechanism 11.

[0058] Preferably, the second focusing lens 24 and the fixing frame 25 are housed within the upper cover 23, and the rotating ring 26 partially extends into the upper cover 23. A sliding groove 233 is provided on the outer circumferential wall of the upper cover 23, and a sliding member 261 is provided on the outer circumferential wall of the rotating ring 26, extending toward the upper cover 23 and extending into the sliding groove 233. Under the action of an external force, the sliding member 261 can slide within the sliding groove 233, allowing the rotating ring 26 to rotate relative to the upper cover 23. At least one latch 251 is provided on the outer circumferential wall of the fixing frame 25, and an oblique receiving groove 262 for receiving the latch 251 is correspondingly provided on the side wall of the rotating ring 26. That is, the receiving groove 262 is arranged at an angle. The inner wall surface of the focusing gear 21 fits against the outer circumferential wall of the rotating ring 26 to drive the rotating ring 26 to rotate, causing the clamping column 251 to slide along the receiving groove 262. When the rotating ring 26 rotates, the fixing frame 25 slides along the receiving groove 262, driving the second focusing lens 24 away from or closer to the first focusing lens 22, thereby achieving the focusing function and making the light spot larger or smaller.

[0059] Combine Figure 12-14As shown, the polarization steering assembly 504 is provided with a polarization gear 31 that cooperates with the second drive mechanism 12 to adjust the lens in the polarization steering assembly 504 via the second drive mechanism 12. Specifically, the second drive mechanism 12 includes a first motor 120 and a first transmission gear 122 disposed on the first motor output shaft 121, as well as a second motor 123 and a second transmission gear 125 disposed on the second motor output shaft 124. The polarization steering assembly 504 includes a first polarization gear 311 meshing with the first transmission gear 122, and a second polarization gear 312 meshing with the second transmission gear 125. When the first motor 120 and / or the second motor 123 are activated, the polarization steering assembly 504 rotates about the axis of the outer frame 501 under the drive of the first transmission gear 122 and / or the second transmission gear 125. The first motor output shaft 121 and the second motor output shaft 124 also extend through the mounting frame 14, and the first transmission gear 122 and the second transmission gear 125 are also located outside the mounting frame 14. The first transmission gear 122 , the second transmission gear 125 and the third transmission gear 111 are all located between the focus gear 21 and the first polarizing gear 311 and the second polarizing gear 312 .

[0060] The polarization steering assembly 504 includes a first lens assembly 32 located below the focusing assembly 503 in the axial direction of the outer frame 501 and a second lens assembly 33 arranged in an annular manner on the outside of the first lens assembly 32. The first lens assembly 32 is rotatably arranged relative to the second lens assembly 33, and the second lens assembly 33 is rotatably arranged relative to the outer frame 501.

[0061] Specifically, the first lens assembly 32 includes a first lens 321 positioned axially of the outer frame 501 and a first bracket 322 disposed around the outside of the first lens 321 for securing the first lens 321. The second lens assembly 33 includes a second lens 331 positioned axially of the outer frame 501 and below the first lens 321, and a second bracket 332 disposed around the outside of the second lens 331 for securing the second lens 331. The second bracket 332 surrounds the outside of the first bracket 322. The polarization deflection assembly 504 is configured to deflect light when the first lens 321 rotates relative to the second lens 331.

[0062] In this embodiment, the first lens 321 and the second lens 331 are preferably two centrosymmetric wedge-shaped structures of equal size. It can be seen that when the two wedge-shaped structures switch from a centrosymmetric to an axisymmetric relative position, the light spot will deflect from the lamp projection area to the outside. When the two wedge-shaped structures are centrosymmetric but not axisymmetric, when the two wedge-shaped structures rotate synchronously, the light spot rotates at a fixed distance from the center point of the lamp projection area, resulting in a circular motion trajectory. Furthermore, when the two wedge-shaped structures are axisymmetric about the horizontal direction, one is a rising wedge structure and the other is a descending wedge structure.

[0063] The first polarizing gear 311 is fixed to the first bracket 322 and is located outside the first lens 321. The second polarizing gear 312 is fixed to the second bracket 332 and is located outside the second lens 331. The first polarizing gear 311 is located below the second polarizing gear 312. Driven by the second driving mechanism 12, the first lens 321 and the second lens 331 rotate relative to each other, thereby changing the thickness of the two lenses and achieving light deflection.

[0064] In this embodiment, the first bracket 322 and the second bracket 332 are arranged at intervals, and the first bracket 322 and the second bracket 332 are rotatably connected through the first bearing 34. The first bracket 322 is also supported in the second bracket 332 through the first bearing 34. The second bracket 332 and the outer frame 501 are rotatably connected through the second bearing 35. The second bearing 35 contacts the inner wall of the outer frame 501, and the second bracket 332 is supported in the outer frame 501 through the second bearing 35.

[0065] like Figure 2 and 3 As shown, the lighting fixture 100 also includes a fixed pressure ring 700 mounted on the second end 202 of the housing 200. That is, the fixed pressure ring 700 is mounted on the end of the housing 200 away from the power supply module 600. The optical integrated module 500 abuts against the fixed pressure ring 700, and the fixed pressure ring 700 is threadedly connected to the inner circumferential wall of the second end 202 of the housing 200. The fixed pressure ring 700 is arranged below the outer frame 501 and abuts against the outer frame 501. Tightening the fixed pressure ring 700 presses the optical integrated module 500 into the housing 200. The multiple contacts on the adapter plate 13 continuously abut against the pins 602 during the rotation of the fixed pressure ring 700. The lighting fixture 100 also includes a reflective cup 800, which includes a primary reflective cup 801 and a secondary reflective cup 802. The primary reflective cup 801 is fixed in the support frame 603 and covers the outer periphery of the light source of the light source module 400. The secondary reflective cup 802 is located below the second lens 331 and is connected to the housing 200 and the fixed pressure ring.

[0066] The electric control process of the optical integrated module 500 is as follows: the first drive mechanism 11 and the second drive mechanism 12 are activated by a remote control. The third motor 112 rotates forward or reverse to drive the focus gear 21, which in turn rotates the rotating ring 26 and drives the fixed frame 25 to move the second focus lens 24 up and down along the axis of the outer frame 501 to achieve the focusing function. Either the first motor 120 or the second motor 123 rotates forward or reverse, driving the corresponding first polarizing gear 311 or second polarizing gear 312 to rotate, which in turn rotates the corresponding first lens 321 or second lens 331, causing the first lens 321 and the second lens 331 to form a relative angle deflection, thereby achieving light deflection. In this embodiment, the light deflection direction is from the center to any direction around, that is, the light output direction is deflected relative to the initial light output direction. The deflection angle is preferably 30°. After the light is deflected, the first motor 120 and the second motor 123 rotate forward or reverse at the same time. The first motor 120 drives the first polarizing gear 311, and the second motor 123 drives the second polarizing gear 312 to rotate at the same speed, thereby causing the first lens 321 and the second lens 331 to rotate synchronously around the axis of the outer frame 501. The deflected light will rotate around the lighting fixture 100 to achieve a steering function.

[0067] In summary, the lighting fixture 100 of the present invention configures the power supply module 600 to include a circuit board 601 and multiple pins 602 integrated on the circuit board 601 and extending toward the optical integration module 500. Furthermore, multiple contacts are provided on the adapter plate 13 of the optical integration module 500. These multiple contacts can then contact the multiple pins 602 to establish an electrical connection with the power supply module 600, thereby enabling the power supply module 600 to power the optical integration module 500. Furthermore, the lighting fixture 100 of the present invention also facilitates easy assembly, disassembly, and replacement of the power supply module and the optical integration module.
