[0002] In the occasion of stage performances, concerts, entertainment venues, etc., stage lamps are the key equipment to create atmosphere and enhance visual effects. Pattern color disc is one of the core components of stage lamps, which is used to project various patterns and color light effects. Traditional pattern color discs are mostly single-layer structures with single function, either only capable of changing patterns or only capable of changing colors, with limited dynamic effects. Some improved color discs combine patterns and color pieces on one layer, such as the patent document with the authorized announcement number "CN105593597B" and the invention name "stage lamp", which produces a new and unexpected stage effect by controlling the change of the main direction of one or more light beams emitted by a single light source of the stage lamp, but the number of combinable effects is still limited, and the complex dynamic effects of independent movement of patterns and colors cannot be achieved.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) This invention allows the three discs to rotate and correspond to different positions on the three discs according to the lighting conditions required on the stage, thereby improving the richness of the lighting pattern matching. At the same time, the multi-layer discs are completely driven and controlled independently, which can realize the synchronous dynamic superposition effect of "rotating pattern + flowing color + fixed texture", creating an unprecedented complex light and shadow art effect and greatly enriching the stage language.

(3) In this invention, each electromagnet in the fixed cylinder is individually controlled by a controller, and the corresponding color, fixed pattern and rotating pattern are selected by energizing the electromagnet. After the electromagnet is energized, the second toothed plate, rotating gear and the first toothed plate drive the locking rod and the positioning rod to disengage. Then the rotating support arm rotates upward to push the positioning rod to move upward and complete the locking. This makes it convenient for the positioning rod in the fixed cylinder that is not in the light emission position to remain fixed, while the positioning rod in the fixed cylinder that is in the light emission position moves upward. (4) In this invention, the positioning rod moves upward after being pushed. When it does not move to the corresponding position, the top of the positioning rod is blocked by the upper plate, so that the positioning rod cannot move upward. The two ends of the conductive rod contact the side contacts respectively, so that the corresponding motor is automatically turned on and the rotation adjustment is completed. When it moves to the corresponding position, the positioning rod continues to move upward to achieve locking, and the conductive rod separates from the side contacts, so that the corresponding motor is automatically turned off, which is convenient to use.

[0018] Example 1, by Figures 1-4 The present invention relates to a multi-layer independent transmission pattern disk and color disk assembly for stage lighting, comprising a color selection mechanism 1, a fixed pattern selection mechanism 2, and a rotating pattern selection mechanism 3.

Color lenses 102, fixed pattern lenses 202, and rotating pattern lenses 302 are respectively arranged at equal angles on the color disk 101, the fixed pattern disk 201, and the rotating pattern disk 301. The rotation of the color disk 101, the fixed pattern disk 201, and the rotating pattern disk 301 drives the color transmission of the desired color, the fixed pattern, and the rotating pattern. The mirror 102, the fixed pattern lens 202, and the rotating pattern lens 302 are moved to positions corresponding to the light emission channel, facilitating multiple selections of stage lighting. A pattern rotating pulley 305 is rotatably mounted on the outer side of the rotating pattern pulley 306. A small toothed ring 303 is rotatably mounted on the rotating pattern lens 302. A large toothed ring 304 is coaxially mounted on the outer side of the pattern rotating pulley 305. The large toothed ring 304 meshes with each of the small toothed rings 303. When the pattern rotating pulley 305 rotates, it drives the large toothed ring 304 to rotate, which in turn drives the rotating pattern lens 302 to rotate continuously through the small toothed rings 303.

[0021] The color disc 101, the fixed pattern disc 201, and the rotating pattern disc 301 are set close together. By rotating the required color lens 102, the fixed pattern lens 202, and the rotating pattern lens 302 to a fixed position, the stage lighting is adjusted by the overlapping color lens 102, the fixed pattern lens 202, and the rotating pattern lens 302.

[0022] The fixed pattern disc main shaft 203 is sleeved on the outside of the color disc main shaft 103. The color disc main shaft 103 has a central shaft 4 installed inside. The central shaft 4 is fixedly installed on the lamp housing. The pattern rotating pulley 305, the rotating pattern disc pulley 306, the fixed pattern disc pulley 204, and the color disc pulley 104 are arranged overlapping from top to bottom. A rotation drive mechanism is provided on the outside of the pattern rotating pulley 305, the rotating pattern disc pulley 306, the fixed pattern disc pulley 204, and the color disc pulley 104.

[0023] The rotation drive mechanism includes a pulley component 6, which includes a driving pulley 6a and a driven pulley 6b. The driven pulley 6b includes a color disc pulley 104, a fixed pattern disc pulley 204, a rotating pattern disc pulley 306, and a pattern rotating pulley 305. A transmission belt 7 is installed on the outside of the driving pulley 6a and the driven pulley 6b. The driving pulley 6a is rotatably mounted on the lamp housing and is fixedly connected to the output shaft of the drive motor 5. The drive motor 5 is fixedly mounted on the lamp housing and includes a first motor, a second motor, a third motor, and a fourth motor. The four motors are used to drive the color disc pulley 104, the fixed pattern disc pulley 204, the rotating pattern disc pulley 306, and the pattern rotating pulley 305 to rotate.

[0024] Example 2, based on Example 1, is... Figures 5-13 Provided, a position positioning mechanism 8 is provided on the color wheel body 101, the fixed pattern wheel body 201, and the rotating pattern wheel body 301. The position positioning mechanism 8 includes rotating positioning members 803 mounted on the color wheel body 101, the fixed pattern wheel body 201, and the rotating pattern wheel body 301. The rotating positioning members 803 include a color wheel positioning member 803a, a fixed pattern positioning member 803b, and a rotating pattern positioning member 803c, all mounted at equal angles on the color wheel body 101. The color wheel positioning member 803a corresponds one-to-one with the color lens 102, the fixed pattern positioning member 803b corresponds one-to-one with the fixed pattern lens 202, and the rotating pattern positioning member 803c corresponds one-to-one with the rotating pattern lens 302. The lengths of the color wheel positioning member 803a, the fixed pattern positioning member 803b, and the rotating pattern positioning member 803c from the central axis 4 are equal. Similarly, a fixing ring 801 is provided above the color disc body 101, and the fixing ring 801 corresponds to the position of the rotating positioning component 803. A positioning groove 802 is provided on the bottom wall of the fixing ring 801. The fixing ring 801 is fixedly installed on the lamp housing. A color disc positioning component 803a is provided on the color disc body 101 corresponding to the color lens 102. A fixed pattern positioning component 803b is provided on the fixed pattern disc body 201 corresponding to the fixed pattern lens 202. A rotating pattern disc body 301 is provided with a fixed pattern positioning component 803b corresponding to the rotating pattern lens 302. 02 Correspondingly, a rotating pattern positioning component 803c is set, and a fixing ring 801 is set above the color disc body 101. The positioning groove 802 opened on the fixing ring 801 corresponds to the position of the light emission channel, so that the positioning rod 8035 in the corresponding fixing cylinder 8031 ​​of each layer can move up and be inserted into the upper positioning groove 802 or the end groove 8032. When the color disc body 101, the fixed pattern disc body 201 and the rotating pattern disc body 301 rotate, the positioning and fixing are automatically achieved, thereby improving the positioning accuracy.

[0025] The rotating positioning component 803 includes a fixed cylinder 8031. The top and bottom ends of the fixed cylinder 8031 ​​are symmetrically provided with end grooves 8032. The inner walls of the fixed cylinder 8031 ​​are symmetrically provided with sliding grooves 8033 on both sides. A movable block 8034 is movably mounted inside the fixed cylinder 8031. A positioning rod 8035 is coaxially mounted on the movable block 8034. The bottom wall of the positioning rod 8035 is flush with the bottom wall of the fixed cylinder 8031. Slider blocks 8036 are symmetrically mounted on both sides of the movable block 8034. The sliders 8036 are slidably connected to the sliding grooves 8033. A first spring 8037 is mounted on the top of the slider 8036. The top of 8037 is fixedly connected to the inner top wall of the slide 8033. The positioning rod 8035 has symmetrically arranged slots 80310 on both sides, located below the movable block 8034. A conductive rod 8038 is installed inside the movable block 8034, with both ends of the conductive rod 8038 penetrating to the side of the slider 8036 away from the movable block 8034. Side contacts 8039 are installed on the inner sidewalls of the two slides 8033, located above the conductive rod 8038. The outer wall of the color disc 101, the outer wall of the fixed pattern disc 201, and the rotating pattern disc 301... An outer conductive ring 804 is installed on the outer wall of each of the three lamp holders. An inner conductive ring 805 is installed on the inner wall of the color disc body 101, the inner wall of the fixed pattern disc body 201, and the inner wall of the rotating pattern disc body 301. Two side contacts 8039 inside the fixed cylinder 8031 ​​are electrically connected to the outer conductive ring 804 and the inner conductive ring 805, respectively. Three fixed contacts 807 are equidistantly installed on the inner wall of the lamp holder housing and the outer wall of the central shaft 4. The six fixed contacts 807 are in contact with the three outer conductive rings 804 and the three inner conductive rings 805, respectively. Each pair of corresponding fixed contacts 807 is electrically connected to the first... The positioning rod 8035 of the first, second, and third motors moves upward under the action of a pushing force. When it does not move to the corresponding position, the top of the positioning rod 8035 is blocked by the upper plate, preventing it from moving upward. The two ends of the conductive rod 8038 contact the side contact 8039, causing the corresponding motor to start automatically and complete the rotation adjustment. When it moves to the corresponding position, the positioning rod 8035 continues to move upward to achieve locking, while the conductive rod 8038 separates from the side contact 8039, causing the corresponding motor to stop automatically. This makes it convenient to use. A rotation pusher 806 is provided below the slider 8036.

[0026] The rotating pusher 806 includes a base 8061 fixedly installed on the inner bottom wall of the slide 8033. Side plates 8062 are symmetrically installed on the top of the base 8061. A snap-fit ​​support module 8064 is provided between the two side plates 8062. Rotating gears 8063 are rotatably installed on the side of the two side plates 8062 that are far apart from each other. A lifting drive module 8065 is connected to the side of the rotating gear 8063 that is far away from the positioning rod 8035.

[0027] The snap-fit ​​support module 8064 includes a rotating support arm 80641 disposed between two side plates 8062. One end of the rotating support arm 80641 is equipped with an end shaft 80642, which is rotatably connected to the side plate 8062. A rod groove 80643 is formed inside the rotating support arm 80641. One end of the rod groove 80643 extends to the end of the rotating support arm 80641 away from the end shaft 80642. A locking rod 80644 is movably installed inside the rod groove 80643. One end of the locking rod 80644 is snapped into the locking groove 80310. A connecting groove 80645 is symmetrically formed on both sides of the rod groove 80643. First toothed plates 80646 are symmetrically installed on both sides of the locking rod 80644. The two first toothed plates 80646 are respectively meshed with the upper part of the two rotating gears 8063. When the rotating support arm 80641 is in a horizontal state, it cannot rotate downwards.

[0028] The lifting drive module 8065 includes a second toothed plate 80653 that meshes with the rotating gear 8063 on the side away from the positioning rod 8035. A movable groove 80651 is provided inside the base 8061. A movable plate 80652 is movably installed inside the movable groove 80651. The movable plate 80652 is fixedly connected to two second toothed plates 80653. Second springs 80654 are symmetrically installed at the bottom end of the movable plate 80652. The bottom end of the second springs 80654 is fixedly connected to the inner bottom wall of the movable groove 80651. A magnet 80655 is installed at the bottom end of the movable plate 80652. An electromagnet 80656 is installed on the inner bottom wall of the movable groove 80651. Each fixed cylinder 8031 ​​has an electromagnet 80656 individually controlled by a controller. The corresponding color, fixed pattern, and rotating pattern are selected by energizing the electromagnet 80656. After the electromagnet 80656 is energized, the second toothed plate 80653, the rotating gear 8063, and the first toothed plate 80646 drive the locking rod 80644 to disengage from the positioning rod 8035. Then, the rotating support arm 80641 rotates upward to push the positioning rod 8035 upward, completing the locking. This makes it convenient for the positioning rod 8035 in the fixed cylinder 8031 ​​that is not in the light-emitting position to remain fixed, while the positioning rod 8035 in the fixed cylinder 8031 ​​that is in the light-emitting position moves upward.

[0029] In Example 3, based on Examples 1 and 2, the first motor, the second motor, and the third motor are all connected to independent control circuits. Instead of simply stacking multiple discs with different functions, each disc can be individually controlled in terms of its motion state, such as rotation / stop, rotation speed, and rotation direction, through independent motors and control circuits. By controlling different motion combinations of the multi-layer discs, an infinite dynamic effect of "dynamic pattern + dynamic color + fixed / fine-tuned background" is achieved, which is a function that traditional single-layer or double-layer color discs cannot achieve.

[0030] Working principle: When it is necessary to adjust the color, fixed pattern and rotating pattern of the stage lights, the first motor, the second motor and the third motor are turned on respectively. The corresponding drive pulley 6a and the transmission belt 7 drive the color disc 101, the fixed pattern disc 201 and the rotating pattern disc 301 to rotate until the required color, fixed pattern and rotating pattern are adjusted to the light emission channel. When the light is emitted, the fourth motor is turned on to drive the pattern rotating pulley 305 to rotate. The large toothed ring 304 on the pattern rotating pulley 305 meshes with each small toothed ring 303, thereby driving the rotating pattern lens 302 to rotate, thus completing the required light emission. The positioning groove 802 on the fixed ring 801 corresponds to the position of the light emission channel, and the two electromagnets 80656 in each fixed cylinder 8031 ​​are connected in series. Each electromagnet 80656 in the fixed cylinder 8031 ​​is individually controlled by the controller. In use, the controller can select the electromagnet 80656 in the corresponding fixed cylinder 8031 ​​to be energized according to the required color, fixed pattern and rotating pattern. At this time, the electromagnet 80656 is energized, generating an attractive force on the magnetic block 80655, pulling the second toothed plate 80653 downwards. Since the second toothed plate 80653 meshes with the rotating gear 8063, it drives the rotating gear 8063 to rotate. The rotating gear 8063 then meshes with the first toothed plate 80646, causing the locking rod 80644 to move away from the positioning rod 8035, disengaging it from the locking slot 80310. At this point, the locking rod 80644 has moved to its limit position. When the first toothed plate 80646 can no longer move, the second toothed plate 80653... Continuing to move downwards, the rotating gear 8063 continues to rotate, which in turn drives the rotating support arm 80641 to rotate upwards around the end shaft 80642, thereby lifting the positioning rod 8035 upwards until the top wall of the positioning rod 8035 contacts the upper plate. At this time, the two ends of the conductive rod 8038 contact the two side contacts 8039 respectively. Here, the upper plate refers to: the upper plate corresponding to the rotating pattern positioning component 803c is the fixed pattern disk 201, the upper plate corresponding to the fixed pattern positioning component 803b is the color disk 101, and the upper plate corresponding to the color disk positioning component 803a is the fixing ring 801. When the two ends of the conductive rod 8038 contact the two side contacts 8039 respectively, the two side contacts 8039 are electrically connected to the outer conductive ring 804 and the inner conductive ring 805 respectively. The outer conductive ring 804 and the inner conductive ring 805 at different positions are electrically connected to the first motor, the second motor, and the third motor respectively through the fixed contact 807. At this time, the corresponding first motor, second motor, and third motor are energized and begin to work, thereby driving the color disc body 101, the fixed pattern disc body 201, and the rotating pattern disc body 301 to rotate. When the color disc body 101 rotates to the position corresponding to the color lens 102 of the desired color and the light emission channel, the corresponding color disc positioning component 803a... Moved to below the positioning groove 802, the positioning rod 8035 is pushed into the positioning groove 802 by the upward rotation of the snap-fit ​​support module 8064, thus positioning and fixing the color disc 101. Similarly, the fixed pattern disc 201 rotates until the positioning rod 8035 on the fixed pattern positioning component 803b is snapped into the color disc positioning component 803a, inside the end groove 8032 at the bottom of the fixed cylinder 8031, thus positioning and fixing the fixed pattern disc 201. The rotating pattern disc 301 rotates until the positioning rod 8035 on the rotating pattern positioning component 803c is snapped into the fixed pattern positioning component 803b, inside the end groove 8032 at the bottom of the fixed cylinder 8031. After the positioning rod 8035 continues to move upward, the conductive rod 8038 separates from the side contact 8039, causing the corresponding drive motor 5 to automatically power off and stop. The first motor, the second motor, and the third motor are motors without a self-locking system.

[0031] Meanwhile, the first, second, and third motors are all connected to independent control circuits. Instead of simply stacking multiple discs with different functions, each disc can be individually controlled in terms of its motion state, such as rotation / stop, rotation speed, and rotation direction, through independent motors and control circuits. By controlling different combinations of motion of the multi-layer discs, an infinite dynamic effect of "dynamic pattern + dynamic color + fixed / fine-tuned background" is achieved, which is a function that traditional single-layer or double-layer color discs cannot achieve.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
