Description

Technical Field

[0001] This invention relates to the field of stage lighting equipment technology, specifically to a stepless dimming strobe pattern cutting light. Background Technology

[0002] In the field of stage lighting equipment, cutting lights are widely used in professional performances, television studios, and large event venues because of their ability to precisely shape light spots. With the maturity of LED light source technology, cutting lights with LED as their core light source are gradually replacing traditional gas discharge bulb light sources due to their advantages such as high efficiency, energy saving, and long lifespan.

[0003] However, existing LED cutting lights still have many shortcomings in terms of functional integration, richness of optical effects, and control precision. Firstly, most traditional cutting lights are single-function, only capable of basic pattern projection or simple color changes, unable to integrate multiple effects such as dimming, strobe, patterning, color mixing, prism, and cutting simultaneously. This necessitates users configuring multiple different types of lights to complete complex stage effect designs, increasing equipment costs and setup complexity. Secondly, the dimming and strobe functions of existing equipment typically rely on independent mechanical devices, making it difficult to achieve smooth, stepless dimming effects, and the adjustment range of strobe frequency and duty cycle is limited. Furthermore, for pattern and color mixing mechanisms, traditional designs are often complex and bulky, and the switching speed and positioning accuracy of pattern disks and color plates cannot meet the demands of high-speed dynamic performances. Regarding prism effects, most equipment is only equipped with a single prism or a simple double-prism structure, unable to achieve the combined rotation and directional motion of the prism, resulting in insufficient expressive power. Finally, as the core component for beam shaping, the cutting mechanism's control over the movement trajectory of its cutting blades, its response speed, and its ability to work in coordination with other optical components (such as apertures and atomizing plates) directly affect the final light output effect of the luminaire. Existing technologies still have considerable room for improvement in this regard. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a pattern cutting lamp that integrates multiple optical effects, has a compact structure, precise control, and can achieve stepless dimming and high-speed strobe.

[0005] To achieve the above technical solution, the present invention provides a stepless dimming strobe pattern cutting lamp, comprising: an LED strobe lamp head, a rotating bracket, and a main unit. The rotating bracket is mounted on the top of the main unit, and the LED strobe lamp head is mounted on the rotating bracket. The LED strobe lamp head includes a lamp head shell, within which an LED strobe light source assembly is installed. A heat dissipation assembly is installed at the bottom of the LED strobe light source assembly. A pattern color mixing mechanism is installed above the LED strobe light source assembly. A cutting mechanism is installed above the pattern color mixing mechanism. A double prism mechanism is installed above the cutting mechanism. An autofocus mechanism is installed above the double prism mechanism. A lamp head front cover is installed on top of the autofocus mechanism. The pattern color mixing mechanism includes a solid... A mounting middle plate is fixed inside the lamp head housing. The middle plate has a central through-hole. A color mixing component is mounted at the bottom of the middle plate. A fixed pattern disk component and a rotating pattern disk component are mounted at the top of the middle plate. The cutting mechanism includes a cutting component mounting plate installed inside the lamp head housing. An aperture mounting plate is mounted at the bottom of the cutting component mounting plate. An adjustable aperture is mounted at the center of the aperture mounting plate. An aperture adjusting external gear is mounted on the outer side of the adjustable aperture. An aperture adjusting transmission gear meshes with the aperture adjusting external gear and is mounted on one side of the aperture adjusting external gear. An aperture adjusting motor is mounted on the cutting component mounting plate and connected to the aperture adjusting transmission gear. Four cutting components are mounted around the adjustable aperture.

[0006] In the above technical solution, the LED strobe light source component in the LED strobe light head is controlled by the host to emit the LED strobe light source. The light source then passes through a pattern mixing mechanism, a cutting mechanism, a double prism mechanism, and an automatic focusing mechanism before being emitted outwards through the front cover of the light head. This stepless dimming strobe pattern cutting light modularly integrates multiple functions such as heat dissipation, light source, pattern mixing, cutting and shaping, prism effect, and automatic focusing into a single light head, achieving multi-functionality in a single lamp and meeting the needs of complex stage scenes. Furthermore, the functional components are arranged in an orderly and compact manner along the light path (from the light source to the light outlet), ensuring maximum utilization of light efficiency and stability of beam transmission. Through the combination of an adjustable aperture and four independent cutting components, the beam can be precisely shaped into any shape. The aperture adjustment motor controls the aperture size through gear transmission, achieving smooth and precise aperture adjustment. Working in conjunction with the cutting blade, it greatly enriches the ability to shape the light spot.

[0007] Preferably, the cutting assembly includes a cutting blade mounting strip, on which a cutting blade is mounted. Movable connecting plates for the cutting blade are mounted on both sides of the mounting strip. A cutting blade drive motor is mounted on the cutting assembly mounting plate and connected to the movable connecting plates via a rocker arm. In actual operation, the rotational motion of the motor is converted into the translational or oscillating motion of the cutting blade through the rocker arm mechanism. This design is simple, reliable, and has a fast response time, enabling rapid and precise control of the cutting blade position, thereby efficiently completing the cutting of the beam shape.

[0008] Preferably, an atomizing plate is mounted at the top center of the cutting component mounting plate above the adjustable aperture. A synchronous pulley for driving the atomizing plate's rotation is mounted on the outer side of the atomizing plate. The atomizing plate drive motor is mounted on the cutting component mounting plate and connected to the synchronous pulley via a synchronous belt. In actual operation, by integrating a rotating atomizing plate above the cutting mechanism, the beam after cutting and shaping can be softened and diffused, achieving a smooth transition from a hard-edged cut light spot to a soft-edged dyed light spot, increasing the variety of light effects of the lamp and enhancing its artistic expression. Furthermore, integrating the atomizing plate with the cutting mechanism and aperture mechanism on the same mounting plate and using a synchronous belt to drive its rotation enables dynamic changes in the atomization effect.

[0009] Preferably, the color mixing assembly includes a bottom mounting plate with a central through hole. A color mixing sheet steering shaft is mounted on one side of the bottom mounting plate near the central through hole. A bottom color mixing sheet, a middle color mixing sheet, and an upper color mixing sheet are mounted on the color mixing sheet steering shaft, arranged side-by-side and spaced apart from bottom to top. A middle color mixing sheet drive motor is mounted at the bottom of the color mixing sheet steering shaft and directly connected to it. A bottom color mixing sheet timing pulley is mounted at the bottom of the color mixing sheet steering shaft. The bottom color mixing sheet is mounted on the bottom color mixing sheet timing pulley. The bottom color mixing sheet drive motor is mounted on one side of the bottom color mixing sheet timing pulley and connected to it via a timing belt. An upper color mixing sheet timing pulley is mounted at the top of the color mixing sheet steering shaft. The upper color mixing sheet is mounted on the upper color mixing sheet timing pulley. The upper color mixing sheet drive motor is mounted on one side of the upper color mixing sheet timing pulley and connected to it via a timing belt. In actual operation, the three independently controlled color mixing layers allow for the overlay and mixing of multiple colors, producing rich color effects. Each color mixing layer is driven by an independent motor, enabling fast and precise color switching and proportion mixing, providing more delicate color selection for dimming.

[0010] Preferably, the fixed pattern disk assembly includes an upper mounting plate with a central through hole. A rotating shaft is mounted on the upper mounting plate, and an upper fixed pattern disk drive pulley and a lower fixed pattern disk drive pulley are mounted on the rotating shaft, arranged parallel to each other. The upper and lower fixed pattern disks are respectively mounted on the upper and lower fixed pattern disk drive pulleys. Upper and lower fixed pattern disk drive motors are mounted on the upper mounting plate and connected to the upper and lower fixed pattern disk drive pulleys respectively via synchronous belts. In actual operation, by setting two independent fixed pattern disks, the lighting fixture can simultaneously store two different fixed patterns. Through rapid switching, rich pattern variations can be achieved without interrupting the performance, increasing the diversity and dynamism of the pattern effects. Furthermore, by setting two fixed pattern disk drive pulleys driven by different motors on the same rotating shaft, independent rotation and selection of the two pattern disks are achieved. This "dual-layer independent drive" fixed pattern disk structure increases the number of patterns and control flexibility within a limited space.

[0011] Preferably, the rotating pattern disk assembly includes a rotating frame mounted on an upper mounting plate. A rotating disk is mounted on the rotating frame, and multiple rotating pattern piece rotation gears are arranged in a circular array around the center of the rotating disk. Each rotating pattern piece rotation gear has a corresponding pattern piece mounted on it. A rotating pattern piece rotation drive gear is mounted at the center of the rotating disk, and the rotating pattern piece rotation drive gear meshes with each of the rotating pattern piece rotation gears. Both the rotating frame drive motor and the rotating pattern piece rotation drive motor are mounted on the upper mounting plate. The rotating frame drive motor is connected to the rotating frame, and the rotating pattern piece rotation drive motor is connected to the rotating pattern piece rotation drive gear. In actual operation, a combined motion of revolution (rotation of the entire rotating disk) and rotation (rotation of a single pattern piece) is achieved. Revolution allows for rapid pattern switching, while rotation changes the projection angle of the pattern. The combination of these two actions creates a dynamic, rotating projection effect, greatly enhancing the visual appeal and artistic impact of the pattern effect.

[0012] Preferably, the double-prism mechanism includes a prism mounting plate with a central light-transmitting hole. An upper prism device is mounted above the mounting plate, and a lower prism device is mounted below it. The upper and lower prism devices have identical structures, each including a prism mounting plate. One lower prism assembly and two upper prism assemblies are mounted on the mounting plate. The lower prism assembly includes a lower prism steering drive motor, a lower prism steering seat mounted on the output shaft of the lower prism steering drive motor, and a lower prism mounted on the lower prism steering seat. The upper prism assembly includes an upper prism rotation drive motor and... The upper prism steering drive motor has a sleeve shaft mounted on its output shaft, and an upper prism steering timing pulley mounted on the sleeve shaft. The upper prism steering drive motor and the upper prism steering timing pulley are connected by a timing belt. An upper prism steering seat is mounted on the upper prism steering timing pulley, and an upper prism rotation drive gear is mounted on the upper prism steering seat. The upper prism rotation drive gear is connected to the output shaft of the upper prism rotation drive motor, and an upper prism rotation gear is mounted at the end of the upper prism steering seat. Upper prism pieces are mounted on the upper prism rotation gear, and the upper prism rotation gear and the upper prism rotation drive gear mesh through an upper prism rotation transition gear. In actual operation, it provides a rich configuration of six prisms in two layers. Each upper prism piece can independently achieve steering (changing the prism's position in the optical path) and rotation (the prism's own rotation), which can create extremely complex and dynamic prism effects, such as beam splitting, rotation, and superposition, greatly enriching the optical effect library of the luminaire.

[0013] Preferably, the autofocus mechanism includes a focusing frame installed inside the lamp head housing. A focusing guide rail is vertically mounted on the focusing frame. Passive and active pulleys, arranged side-by-side at intervals, are mounted on the left and right sides of the focusing guide rail, respectively. The passive and active pulleys are connected by a transmission belt. A pulley drive motor is mounted behind and connected to the active pulley. A movable bracket is mounted on the focusing guide rail via a slider, and its left and right sides are connected to the transmission belts on the left and right sides of the focusing guide rail, respectively. A fixed optical lens is fixed to the top of the focusing frame via a fixed optical lens mounting bracket. A movable optical lens is fixed to the movable bracket, and the movable optical lens is vertically aligned with the fixed optical lens. In actual operation, the movable optical lens moves up and down via the pulley and guide rail system, achieving fast, stable, and precise autofocus. Regardless of changes in the patterns, cuts, prisms, or other optical elements at the front of the lamp, this mechanism can quickly adjust the focus, ensuring that the projected light spot remains clear.

[0014] Preferably, the LED strobe light source assembly includes an LED strobe light source mounting plate, an LED strobe light source generator mounted on the mounting plate, and the LED strobe light source generator vertically upwards, directly facing the central through-hole on the pattern mixing mechanism. A light source control chip is mounted on one side of the LED strobe light source generator and electrically connected to it. In actual operation, the LED strobe light source generator is directly electronically controlled by the light source control chip, achieving true "stepless dimming" and high-speed strobe. Compared to mechanical dimming / strobe, electronic control offers significant advantages such as a smooth dimming curve, a wide strobe frequency range, no noise, and fast response speed.

[0015] Preferably, the heat dissipation assembly includes a heat sink and cooling fans. The heat sink is installed flush against the bottom of the LED strobe light generator, and the cooling fans are installed on the left and right sides of the heat sink, facing it directly. The heat sink, flush against the bottom of the LED strobe light generator, directly conducts heat. Simultaneously, the two cooling fans are symmetrically installed on the left and right sides of the heat sink, facing it directly, forming a "two-way side-blowing" airflow design. Compared to traditional single-fan or bottom-blowing designs, this design more effectively removes heat from the heat sink, preventing heat accumulation at the bottom of the lamp head.

[0016] The beneficial effects of the stepless dimming strobe pattern cutting lamp provided by this invention are as follows: (1) This stepless dimming strobe pattern cutting light integrates ten core optical functions into one lamp, including stepless dimming, high-speed strobe, multi-layer color mixing, double fixed pattern disks, rotating pattern disks (revolution + rotation), four-piece cutting system, adjustable aperture, rotating atomizing sheet, double-layer multi-prism (direction + rotation), and automatic focusing. The functional modules are arranged in an orderly manner along the light path, with a compact structure. The control system enables the coordinated operation of each function, creating a good composite visual effect. One device can meet the complex stage requirements that would normally require multiple devices.

[0017] (2) This stepless dimming stroboscopic pattern cutting lamp achieves stepless and smooth dimming and a wide-range, high-precision stroboscopic effect through electronic control of the LED light source. The composite motion of the multi-layer pattern, color mixing, and prism system (such as the revolution and rotation of the pattern piece, and the turning and rotation of the prism) provides the beam with extremely strong dynamic expression and artistic rendering power. The cooperation between the cutting mechanism and the aperture and atomizing plate realizes the precise beam shaping from hard-edge graphics to soft-edge coloring, and from regular shapes to arbitrary shapes, which greatly expands the application scenarios of the lamp.

[0018] (3) Each functional mechanism of this stepless dimming strobe pattern cutting lamp adopts a highly compact and modular design, such as a "coaxial independent drive" color mixing plate, a "double-layer independent drive" fixed pattern plate, and a "one-drive-multiple" rotating pattern plate self-rotation structure, which enables complex functions to be realized in a limited space, making it easy to produce, assemble and maintain, and improving the reliability and cost performance of the product.

[0019] (4) The moving parts of this stepless dimming stroboscopic pattern cutting lamp adopt a large number of precision transmission mechanisms such as motors, synchronous belts, and gears, combined with electronically controlled light source chips, to ensure rapid response and high-precision positioning of operations such as pattern switching, color mixing, cutting blade movement, prism turning / rotation, aperture adjustment and automatic focusing, thus meeting the stringent requirements of professional stage performances for the dynamic performance of lighting fixtures.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0039] Example: A stepless dimming stroboscopic pattern cutting lamp.

[0040] Reference Figures 1 to 3 As shown, a stepless dimming strobe pattern cutting light includes: an LED strobe head 1, a rotating bracket 2, and a main unit 3. The rotating bracket 2 is mounted on the top of the main unit 3, and the LED strobe head 1 is mounted on the rotating bracket 2. In actual operation, the main unit 3 controls the rotating bracket 2 to drive the LED strobe head 1 to pitch in the vertical plane and rotate in the horizontal plane, so that the LED strobe head 1 can achieve omnidirectional dynamic scanning and positioning.

[0041] Reference Figure 3 and Figure 17 As shown, the LED strobe lamp head 1 includes a lamp head housing 11, within which an LED strobe light source assembly 17 is installed. The LED strobe light source assembly 17 includes an LED strobe light source mounting plate 171, and an LED strobe light source generator 173 is mounted on the mounting plate 171. The LED strobe light source generator 173 is vertically upward, directly facing the central through-hole 166 on the pattern color mixing mechanism 16. A light source control chip 172 is installed on one side of the LED strobe light source generator 173 and electrically connected to it. In actual operation, the LED strobe light source generator 173 is directly electronically controlled by the light source control chip 172, achieving true "stepless dimming" and high-speed strobe. Compared to mechanical dimming / strobe, electronic control offers significant advantages such as a smooth dimming curve, a wide strobe frequency range, no noise, and fast response speed.

[0042] Reference Figure 3 and Figure 17As shown, a heat dissipation assembly 18 is installed at the bottom of the LED strobe light source assembly 17. The heat dissipation assembly 18 includes a heat sink 181 and a cooling fan 182. The heat sink 181 is installed close to the bottom of the LED strobe light source generator 173, and the cooling fan 182 is installed on the left and right sides of the heat sink 181 and directly facing the heat sink 181. The heat sink 181 is close to the bottom of the LED strobe light source generator 173, directly conducting heat. At the same time, the two cooling fans 182 are symmetrically installed on the left and right sides of the heat sink 181 and directly facing the heat sink 181, forming a "two-way side-blowing" airflow design. Compared with the traditional single fan or bottom-blowing design, this design can more effectively remove the heat from the heat sink 181 and prevent heat from accumulating at the bottom of the lamp head.

[0043] Reference Figures 13 to 15 As shown, a pattern mixing mechanism 16 is installed above the LED strobe source assembly 17. The pattern mixing mechanism 16 includes a mounting middle plate 161 fixed inside the lamp head housing 11. A central through hole 166 is provided in the middle of the mounting middle plate 161. A color mixing component 165 is installed at the bottom of the mounting middle plate 161. A fixed pattern disk assembly 162 and a rotating pattern disk assembly 163 are installed at the top of the mounting middle plate 161. A cooling fan 164 is installed on one side of the fixed pattern disk assembly 162 and the rotating pattern disk assembly 163. The color mixing component 165 includes a bottom mounting plate 1651 with a central through hole 166. A color mixing sheet steering sleeve 1657 is mounted on one side of the bottom mounting plate 1651 near the central through hole 166. A bottom color mixing sheet 1658, a middle color mixing sheet 1656, and an upper color mixing sheet 1655 are mounted on the color mixing sheet steering sleeve 1657, arranged side-by-side and spaced apart from bottom to top. A middle color mixing sheet drive motor 16511 is mounted at the bottom of the color mixing sheet steering sleeve 1657 and directly connected to it. The bottom layer color mixing sheet is mounted at the bottom of the color mixing sheet steering sleeve 1657. A color mixing layer synchronous pulley 1659 is used. A bottom color mixing layer 1658 is mounted on this pulley. A bottom color mixing layer drive motor 16510 is mounted on one side of the bottom color mixing layer synchronous pulley 1659 and connected to it via a synchronous belt. An upper color mixing layer synchronous pulley 1654 is mounted on the top of the color mixing layer steering shaft 1657. An upper color mixing layer 1655 is mounted on this pulley. An upper color mixing layer drive motor 1652 is mounted on one side of the upper color mixing layer synchronous pulley 1653 and connected to it via a synchronous belt. In actual operation, the three independently controlled color mixing layers allow for the superposition and mixing of multiple colors, producing rich color effects. Each color mixing layer is driven by an independent motor, enabling fast and precise color switching and proportion mixing, providing more delicate color selection for dimming.

[0044] Reference Figures 13 to 15 As shown, the fixed pattern disk assembly 162 includes an upper mounting plate 1621 with a central through hole 166. A rotating sleeve 1625 is mounted on the upper mounting plate 1621, and an upper fixed pattern disk drive pulley 1624 and a lower fixed pattern disk drive pulley 1622 are mounted on the rotating sleeve 1625, which are arranged parallel to each other. The upper fixed pattern disk 1626 and the lower fixed pattern disk 1623 are respectively mounted on the upper fixed pattern disk drive pulley 1624 and the lower fixed pattern disk drive pulley 1622. The upper fixed pattern disk drive motor 1628 and the lower fixed pattern disk drive motor 1627 are mounted on the upper mounting plate 1621 and are respectively connected to the upper fixed pattern disk drive pulley 1624 and the lower fixed pattern disk drive pulley 1622 via synchronous belts. In actual operation, by setting up two independent fixed pattern discs (upper and lower), the lighting fixture can simultaneously store two different sets of fixed patterns. Through rapid switching, rich pattern variations can be achieved without interrupting the performance, increasing the diversity and dynamism of the pattern effects. Furthermore, two drive pulleys for the fixed pattern discs, each driven by a different motor, are set on the same rotating shaft 1625, enabling independent rotation and selection of the two pattern discs. This "dual-layer independent drive" fixed pattern disc structure increases the number of patterns and control flexibility within a limited space.

[0045] Reference Figures 13 to 15 As shown, the rotating pattern disk assembly 163 includes a rotating frame 1635 mounted on an upper mounting plate 1621. A rotating disk 1636 is mounted on the rotating frame 1635. A plurality of rotating pattern piece rotation gears 1634 are arranged in a circular array with the center of the rotating disk 1636 as the center. Each rotating pattern piece rotation gear 1634 is equipped with a corresponding pattern piece. A rotating pattern piece rotation drive gear 1633 is mounted at the center of the rotating disk 1636. The rotating pattern piece rotation drive gear 1633 meshes with each rotating pattern piece rotation gear 1634. A rotating frame drive motor 1631 and a rotating pattern piece rotation drive motor 1632 are both mounted on the upper mounting plate 1621. The rotating frame drive motor 1631 is connected to the rotating frame 1635, and the rotating pattern piece rotation drive motor 1632 is connected to the rotating pattern piece rotation drive gear 1633. In actual operation, a composite motion of revolution (rotation of the entire rotating disk) and rotation (rotation of individual pattern pieces) is achieved. Revolution allows for rapid pattern switching, while rotation changes the projection angle of the pattern. The combination of the two creates a dynamic, rotating projection effect, greatly enhancing the visual appeal and artistic impact of the pattern effects.

[0046] Reference Figures 10 to 12As shown, a cutting mechanism 15 is installed above the pattern mixing mechanism 16. The cutting mechanism 15 includes a cutting component mounting plate 151 installed inside the lamp head housing 11. An aperture mounting plate 157 is installed at the bottom of the cutting component mounting plate 151. An adjustable aperture 154 is installed at the center of the aperture mounting plate 157. An aperture adjusting external gear 158 is installed on the outer side of the adjustable aperture 154. An aperture adjusting transmission gear 156, which meshes with the aperture adjusting external gear 158, is installed on one side of the aperture adjusting external gear 158. An aperture adjusting motor 155 is installed on the cutting component mounting plate 151 and connected to the aperture adjusting transmission gear 156. Four cutting components 153 are installed around the adjustable aperture 154. In actual operation, the aperture adjusting motor 155 drives the aperture adjusting transmission gear 156 to rotate the aperture adjusting external gear 158, thereby adjusting the aperture size of the adjustable aperture 154. The cutting assembly 153 includes a cutting blade mounting strip 1533, on which a cutting blade 1531 is mounted. Cutting blade movable connecting plates 1532 are mounted on both the left and right sides of the cutting blade mounting strip 1533. A cutting blade drive motor 1534 is mounted on the cutting assembly mounting plate 151 and is connected to the cutting blade movable connecting plates 1532 via a rocker arm 1535. In actual operation, the rotational motion of the cutting blade drive motor 1534 is converted into the translational or oscillating motion of the cutting blade 1531 through the rocker arm 1535 mechanism. This design is simple, reliable, and has a fast response speed, enabling rapid and precise control of the position of the cutting blade 1531, thereby efficiently completing the cutting of the beam shape. Various shapes can be produced through the cooperation of the cutting blades 1531 in the four cutting assemblies 153, greatly enriching the lighting effects. An atomizing plate 1512 is mounted on the top center of the cutting component mounting plate 151 above the adjustable aperture 154. A self-rotating synchronous pulley 1511 is mounted on the outer side of the atomizing plate 1512. An atomizing plate drive motor 1510 is mounted on the cutting component mounting plate 151 and connected to the self-rotating synchronous pulley 1511 via a synchronous belt. In actual operation, by integrating a self-rotating atomizing plate 1512 above the cutting mechanism 15, the cut and shaped light beam can be softened and diffused, achieving a smooth transition from a hard-edged cut light spot to a soft-edged dyed light spot, increasing the variety of light effects and enhancing the artistic expression of the lamp. Furthermore, integrating the atomizing plate 1512 with the cutting mechanism and aperture mechanism on the same mounting plate and using a synchronous belt to drive its rotation enables dynamic changes in the atomization effect.

[0047] Reference Figures 8 to 9As shown, a double prism mechanism 14 is installed above the cutting mechanism 15. The double prism mechanism 14 includes a prism device mounting partition 141. A central light-transmitting hole 144 is provided in the center of the prism device mounting partition 141. An upper prism device 142 is installed above the prism device mounting partition 141, and a lower prism device 143 is installed below the prism device mounting partition 141. The upper prism device 142 and the lower prism device 143 have the same structure, both including a prism mounting plate 1421. One lower prism assembly and two upper prism assemblies are installed on the prism mounting plate 1421. The lower prism assembly includes a lower prism steering drive motor 1422. A lower prism steering seat 1423 is installed on the output shaft of the lower prism steering drive motor 1422, and a lower prism 1424 is installed on the lower prism steering seat 1423. The upper prism assembly includes an upper prism rotation drive motor 142. 5. An upper prism steering drive motor 14210 is mounted on the output shaft of the upper prism rotation drive motor 1425. An upper prism steering timing pulley 1427 is mounted on the timing pulley. The upper prism steering drive motor 14210 and the upper prism steering timing pulley 1427 are connected by a timing belt. An upper prism steering seat 1428 is mounted on the upper prism steering timing pulley 1427. An upper prism rotation mechanism is mounted on the upper prism steering seat 1428. The drive gear 1426 is connected to the output shaft of the upper prism rotation drive motor 1425. An upper prism rotation gear 14211 is mounted at the end of the upper prism steering seat 1428. An upper prism piece 14212 is mounted on the upper prism rotation gear 14211. The upper prism rotation gear 14211 and the upper prism rotation drive gear 1426 mesh through an upper prism rotation transition gear 1429. In actual operation, this double-prism mechanism 14 provides a rich configuration of six prisms in two layers. Each upper prism piece 14212 can independently achieve steering (changing the prism's position in the optical path) and rotation (the prism's own rotation), creating extremely complex and dynamic prism effects, such as beam splitting, rotation, and superposition, greatly enriching the optical effect library of the lighting fixture.

[0048] Reference Figures 5 to 7As shown, an autofocus mechanism 13 is installed above the double prism mechanism 14, and a lamp head front cover 12 is installed on top of the autofocus mechanism 13. The autofocus mechanism 13 includes a focusing frame 131 installed inside the lamp head housing 11. A focusing guide rail 134 is vertically arranged on the focusing frame 131. Passive pulleys 135 and driving pulleys 136 are respectively installed on the left and right sides of the focusing guide rail 134, arranged side-by-side at intervals. The passive pulleys 135 and driving pulleys 136 are connected by a transmission belt 139. A motor 137 is mounted behind and connected to the drive pulley 136. A movable bracket 1310 is mounted on the focusing guide rail 134 via a slider 138, and the left and right sides of the movable bracket 1310 are respectively connected to the transmission belts 139 located on the left and right sides of the focusing guide rail 134. A fixed optical lens 133 is fixed to the top of the focusing frame 131 via a fixed optical lens mounting bracket 132. A movable optical lens 1311 is fixed on the movable bracket 1310, and the movable optical lens 1311 is vertically aligned with the fixed optical lens 133. In actual operation, the movable optical lens 1311 is driven to move up and down by the pulley and guide rail system to achieve fast, stable, and precise automatic focusing. Regardless of changes in the patterns, cuts, prisms, or other optical elements at the front of the lamp, this mechanism can quickly adjust the focus to ensure that the projected light spot is always clear.

[0049] In this embodiment, during actual operation, the LED strobe light source component 17 in the LED strobe light head 1 is controlled by the host 3 to emit the LED strobe light source. The light source then passes through the pattern mixing mechanism 16, the cutting mechanism 15, the double prism mechanism 14, and the autofocus mechanism 13 in sequence before finally being emitted outwards via the front cover 12 of the light head. This stepless dimming strobe pattern cutting light modularly integrates multiple functions such as heat dissipation, light source, pattern mixing, cutting and shaping, prism effect, and autofocus into a single light head, achieving multi-functionality in a single lamp and meeting the needs of complex stage scenes. Furthermore, the functional components are arranged in an orderly and compact manner along the light path (from the light source to the light outlet), ensuring maximum utilization of light efficiency and stability of beam transmission. Through the combination of the adjustable aperture 154 and four independent cutting components 153, the beam can be precisely shaped into any shape. The aperture adjustment motor controls the aperture size through gear transmission, achieving smooth and precise aperture adjustment. Working in conjunction with the cutting blade, it greatly enriches the ability to shape the light spot.

[0050] This stepless dimming stroboscopic pattern cutting light highly integrates ten core optical functions into a single fixture, including stepless dimming, high-speed stroboscopic effect, multi-layer color mixing, dual fixed pattern discs, rotating pattern discs (revolution + rotation), a four-piece cutting system, adjustable aperture, rotating atomizing disc, double-layer multi-prism (direction + rotation), and automatic focusing. The functional modules are arranged in an orderly manner along the optical path, resulting in a compact structure. Through a control system, these functions can work collaboratively to create excellent composite visual effects. One device can meet the complex stage requirements that would traditionally require multiple devices. Furthermore, this stepless dimming stroboscopic pattern cutting light achieves stepless, smooth dimming and a wide-range, high-precision stroboscopic effect through electronically controlled LED light sources. The composite movement of the multi-layered pattern, color mixing, and prism system (such as pattern disc revolution + rotation, prism direction + rotation) provides the beam with extremely strong dynamic expressiveness and artistic rendering power. The cutting mechanism, in conjunction with the aperture and atomizing plate, enables precise beam shaping from hard-edge graphics to soft-edge tinting, and from regular shapes to arbitrary shapes, greatly expanding the application scenarios of lighting fixtures.
