Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an automatic rotating dimming stage light mainly used for performances or entertainment in stages, entertainment venues, and large-scale performances. Background Technology

[0002] In the field of stage lighting, existing stage lights typically have optical dimming components, such as honeycomb lenses, grilles, or light-shielding doors, placed in front of the light source in their internal dimming structure. These optical components are usually fixedly mounted on a lens disk or bracket, maintaining a fixed relative position with the auxiliary light source (or secondary light), forming a static optical system. This type of structure is widely found in existing spotlights, color-changing lights, and other lighting fixtures, and its function is to produce a fixed-angle beam of light with clear boundaries and a sharp light quality.

[0003] However, the aforementioned existing technical solutions have significant limitations. First, because the optical components and the light source are fixedly connected, the resulting beam angle and spot shape are static and unchanging. Dynamic changes in beam angle and light intensity cannot be achieved during the lighting operation, resulting in a limited range of lighting effects that fails to meet the creative demands of modern performances for dynamic and gradual lighting effects. Second, achieving different beam angles typically requires stopping the system and manually replacing optical components of different specifications. This is cumbersome, disrupts the continuity of the performance, and lacks real-time controllability. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As attached Figure 1-10As shown in the embodiment of this utility model, an automatic rotating and dimming stage light includes a control base 1, a support frame 2 disposed on the control base 1, and a lamp body rotatably mounted between the support frame 2 via a horizontal and vertical axis rotation mechanism. The lamp body is electrically connected to the control base 1 via an internal cable. The control base 1 integrates a professional lighting control unit, which is equipped with a standard DMX512 or Art-Net protocol receiving interface, and can seamlessly access a professional stage lighting control network to receive control signals from a dimming console, thereby achieving remote, precise, and synchronous control of all parameters such as lamp brightness, color, rotation speed, and focus position.

[0031] Reference Figure 2 The lamp body includes a lamp body shell 3, a heat dissipation unit, and a light-emitting unit. The heat dissipation unit and the light-emitting unit are both installed inside the lamp body shell 3. The light-emitting unit is the part that realizes the core light effect. It includes a main light source device 7, a focusing device 8, and an auxiliary dimming device 9. The main light source device 7 is located on top of the heat dissipation unit. The focusing device 8 is connected between the heat dissipation unit and the auxiliary dimming device 9, and supports the auxiliary dimming device 9 on the light output path of the main light source device 7. The auxiliary dimming device 9 includes a rotation drive 91 and an optical component 92 that can be driven to rotate by the rotation drive 91. The rotation of the optical component 92 can dynamically change the light distribution passing through it, thereby dynamically adjusting the beam angle and light intensity of the emitted light. The auxiliary dimming device 9 also includes a dimming base plate 93, a light-blocking frame 94, a rotating output component 95, and an auxiliary light source component 96. The light-blocking frame 94 is located on the top of the dimming base plate 93. The auxiliary light source component 96 is fitted onto the top surface of the light-blocking frame 94. The rotating output component 95 is rotatably located at the center of the dimming base plate 93 and the light-blocking frame 94. The rotating drive component 91 is installed at the bottom of the dimming base plate 93 and is connected to the rotating output component 95. The optical component 92 is connected to the top of the rotating output component 95 and suspended above the auxiliary light source component 96, with a certain light transmission interval between them to ensure that the light can be diffused evenly. The two sides of the dimming base plate 93 are respectively connected to the focusing device 8.

[0032] The rotating output component 95 includes a bearing 951, a rotating shaft 952, and a rotating pulley 953. The bearing 951 is fixedly installed in the center mounting holes corresponding to the dimming base plate 93 and the light blocking frame 94. The rotating shaft 952 is rotatably supported at the center of the dimming base plate 93 and the light blocking frame 94 via the bearing 951. The rotating pulley 953 is sleeved on the bottom end of the rotating shaft 952 and is connected to the rotating drive component 91. The optical component 92 is connected to the top end of the rotating shaft 952. When the rotating drive component 91 drives the rotating pulley 953, the torque is transmitted through the rotating shaft 952, ultimately driving the optical component 92 to rotate synchronously.

[0033] In a preferred embodiment of this utility model, the rotary drive component 91 is a belt drive mechanism, specifically including a drive motor 911, a belt 912, and a belt protective cover 913. The drive motor 911 is mounted on the dimming base plate 93, and its output axis extends downward to accommodate a drive wheel 914. Several tensioning wheels 915 are spaced apart on the path of the belt 912 between the drive wheel 914 and the rotating pulley 953 to maintain appropriate tension on the belt 912 and prevent slippage and vibration. The belt 912 is sequentially wrapped around the drive wheel 914, several tensioning wheels 915, and the rotating pulley 953 to form a transmission circuit. The belt protective cover 913 covers the outside of the transmission area of ​​the belt 912, providing safety protection and preventing dust and debris from being drawn in.

[0034] When the drive motor 911 rotates, the power is transmitted to the rotating shaft 952 through the drive wheel 914, belt 912, tension wheel 915, and rotating pulley 953, causing it to rotate, which in turn drives the optical component 92 to rotate.

[0035] It is understood that the rotary drive component 91 can also adopt other transmission forms; for example, in an alternative embodiment, a gear transmission mechanism can be used, that is, a drive gear is provided on the output shaft of the drive motor 911, and a driven gear is fixedly installed at the bottom end of the rotating shaft 952 of the rotary output component 95. Several pairs of gears mesh between the drive gear and the driven gear, thereby forming a meshing transmission circuit, which can also realize power transmission and rotation.

[0036] Furthermore, it is understandable that the rotary drive component 91 is designed with layout adaptability, and its installation position can be optimized and adjusted according to the actual structural space. Specifically, for example, the rotary drive component 91 can be located on one side of the auxiliary dimming device 9; regardless of the position change, the rotary drive component 91 can be effectively connected to the rotating shaft 952 of the rotary output component 95 through specific connecting parts, such as universal joints, gear sets, couplings, transmission belts, etc., thereby forming a complete transmission circuit, ensuring that power is effectively transmitted and driving the optical component 92 to rotate.

[0037] In a preferred embodiment of this utility model, the rotary drive component 91 can cooperate with the rotary output component 95 to achieve automatic and continuous smooth rotation through precise control of the optical component 92, making the transition of light spot changes natural and greatly enhancing the expressiveness and automation of lighting art; in addition, the rotary drive component 91 can also cooperate with the rotary output component 95 to realize complex rotation modes such as intermittent and variable speed according to programming to meet diverse stage lighting needs; its control method can be automatic or respond to external signals or manual input.

[0038] The optical component 92 includes a mounting bracket 921 and a plurality of optical lenses 922 fixedly mounted on the mounting bracket 921. The mounting bracket 921 is fixedly connected to the top end of the rotating shaft 952, and the plurality of optical lenses 922 are arranged in an array.

[0039] The mounting bracket 921 consists of an upper cover and a lower cover. The upper cover and the lower cover have a number of mounting slots 923. The optical lens 922 is fixedly set in the mounting slot 923 by inlaying, snapping or bonding. The cross-sectional shape of the mounting slot 923 can be designed into a variety of regular patterns as needed, such as honeycomb holes, orthogonal grids, parallel stripes or irregular holes. The shape of the optical lens 922 is adapted to the shape of the mounting slot 923.

[0040] When the cross-sectional shape of the mounting slot 923 is designed as a honeycomb hole, the mounting slot 923 is hexagonal, and the mounted optical lens 922 is a honeycomb-eye lens of the same shape, used to generate a circular spot with soft edges and eliminate stray light.

[0041] When the cross-sectional shape of the mounting slot 923 is designed as an orthogonal grid, the mounting slot 923 is a square or rectangular grid, and the installed optical lens 922 is a grid lens of the same shape, which can produce a light spot with grid shadow.

[0042] When the cross-sectional shape of the mounting groove 923 is designed as parallel stripes, the mounting groove 923 is a striped groove with equal spacing, and the optical lens 922 installed is a cylindrical lens or grating sheet of the same shape, which can produce parallel stripe light effect.

[0043] When the cross-sectional shape of the mounting slot 923 is designed as an irregular hole, the mounting slot 923 can be a specific pattern such as a star or snowflake. The optical lens 922 installed is a lens of the same custom shape, which can directly project the light spot of the pattern.

[0044] Specifically, regardless of its shape, the shape of the optical lens 922 is closely matched with the shape of the mounting groove 923 to ensure accurate positioning; and the optical lens 922 can be a honeycomb lens, a Fresnel lens or other lenses with microstructures, the function of which is to redistribute light; when the mounting bracket 921 rotates with the rotating shaft 952, these optical lenses 922 periodically cut and modulate the light emitted by the auxiliary light source 96 below.

[0045] The auxiliary light source 96 includes an auxiliary light source board 961 and a plurality of auxiliary lamps 962 disposed thereon, wherein the auxiliary lamps 962 are arranged at equal intervals or at non-equal intervals.

[0046] When using equal spacing, the spacing ensures the uniformity of the light-emitting surface and avoids hot spots. When using non-equal spacing, the spacing can be configured according to the shape of the target light spot, and different spacing patterns (such as gradient, random, etc.) can be designed. The gaps formed by equal or non-equal spacing can provide the possibility of light emanating from multiple angles. When combined with a rotating lens above, it can form richer and more three-dimensional dynamic light effects to meet diverse stage lighting needs.

[0047] Specifically, the auxiliary lamp 962 can be made of low-power LED beads or laser diodes.

[0048] The heat dissipation unit includes a mounting plate 4, a radiator 5, and a fan 6. The radiator 5 and the fan 6 are located below the mounting plate 4, which is beneficial for heat dissipation inside the lamp body. The main light source device 7 is located on the top of the mounting plate 4. One end of the focusing device 8 is fixed on the mounting plate 4, and the other end is connected to the auxiliary dimming device 9.

[0049] In a preferred embodiment of the present invention, the focusing device 8 is provided in two sets, symmetrically distributed on the left and right sides of the auxiliary dimming device 9. Each set of focusing devices 8 includes a set of focusing drive components 81, a set of focusing slide components 82 and a set of focusing guide components 83. The devices on both sides work synchronously to achieve precise and balanced linear movement of the auxiliary dimming device 9 relative to the main light source device 7.

[0050] Taking one side as an example, the focusing drive component 81 includes a focusing motor 811 disposed on one side of the mounting plate 4, and the focusing motor 811 is covered by a motor protective cover 812; the focusing sliding component 82 includes a sliding nut 821 fixed to the bottom of the dimming base plate 93 of the auxiliary dimming device 9 on one side, and a set of focusing sliding sleeves 822 fixed to one side of the dimming base plate 93 by a pressure plate and a support column; the sliding nut 821 is fixed to the bottom of the dimming base plate 93, the focusing guide component 83 is arranged in parallel, and its two ends are fixedly connected to the mounting plate 4 and the auxiliary dimming device 9 respectively, providing sliding guidance for the auxiliary dimming device 9, and the focusing sliding sleeves 822 are slidably connected to the focusing guide component 83; the output axis of the focusing motor 811 extends upward and is driven to connect with the sliding nut 821 through a thread to form a screw nut pair, so as to drive the auxiliary dimming device 9 to move along the focusing guide component 83, that is, to move along the optical axis direction of the main light source device 7. The focusing drive 81 and focusing slider 82 on the other side have the same symmetrical structure.

[0051] For details, please refer to the following: Figure 3-4Taking one side as an example, the focusing guide 83 includes a connecting support 831, two parallel focusing shafts 832, and a limiting plate 833. The connecting support 831 is fixed to the mounting plate 4. The two focusing shafts 832 pass through a pressure plate, a corresponding focusing sleeve 822, and a dimming base plate 93 in sequence and are connected and fixed to the connecting support 831. Their top ends are connected and fixed to the limiting plate 833. The focusing sleeve 822 can slide on the focusing shaft 832. Connecting posts 834 are provided on both sides of the connecting support 831, and the top ends of the connecting posts 834 are connected and fixed to both sides of the limiting plate 833. The limiting plate 833 is used to limit the maximum stroke of the auxiliary dimming device 9. The focusing guide 83 on the other side has the same symmetrical structure.

[0052] When the focusing motor 811 rotates, its output shaft rotates. Since the sliding nut 821 is fixed on the dimming base plate 93 and cannot rotate, it generates a precise linear motion along its axial direction (i.e., the vertical direction) under the drive of the output shaft. This motion drives the entire auxiliary dimming device 9 and the focusing sleeve 822 installed on it through the sliding nut 821, smoothly rising or falling along the vertical track determined by the fixed focusing shaft 832 and the connecting column 834, thereby realizing the focal length adjustment of the entire auxiliary dimming device 9 relative to the main light source device 7. The cooperation between the focusing sleeve 822 and the focusing shaft 832 ensures smooth movement and low friction, while the two connecting columns 834 enhance the torsional rigidity and movement stability of the structure.

[0053] It is understood that the two sets of focusing devices 8 described above are merely examples and not limitations. Depending on the actual load and accuracy requirements, the focusing devices 8 can also be configured as two or more sets (e.g., three sets evenly distributed circumferentially), the core of which lies in achieving balanced and stable drive through multiple guiding units.

[0054] The main light source device 7 includes a carrier plate 71, a plurality of main lights 72 and a plurality of light guide columns 73. The plurality of main lights 72 are arranged in an array on the carrier plate 71, and each light guide column 73 is correspondingly set above the main light 72 through a light guide bracket to provide the required high-brightness basic lighting for the stage lights. The main lights 72 can be selected from high-power LED beads or laser diodes.

[0055] In a specific embodiment of this utility model, the mounting bracket 921 in the auxiliary dimming device 9 is provided with a plurality of honeycomb-shaped holes in the mounting groove 923, and the plurality of mounting grooves 923 surround to form a concentric ring array composed of an outer ring and an inner ring; the dimming base plate 93 and the light-blocking frame 94 are also provided with a plurality of honeycomb-shaped holes corresponding to the mounting bracket 921. The main light source device 7 located below the dimming base plate 93 and the light-blocking frame 94 has a main lamp 72 and a light guide column 73 respectively arranged on its support plate 71 corresponding to each hole and groove. The holes and grooves of the light-blocking frame 94 can be used to constrain the emitted light of each main lamp of the main light source device 7, while the auxiliary light source component is fitted onto the partition between adjacent holes and grooves, avoiding the holes and grooves of the light-blocking frame 94.

[0056] For details, please refer to the following: Figure 8 When the optical component 92 is in the initial state, the auxiliary lamps 962 of the auxiliary light source component 96 are all blocked by the partitions between adjacent mounting slots 923. At this time, the amount of emitted light is small and the light spot intensity is weak.

[0057] For details, please refer to the following: Figure 9 When the optical component 92 rotates 15 degrees, the auxiliary lamp 962 located on the outer ring of the auxiliary light source component 96 is exposed at the center of the outer ring mounting groove 923, and the light source is projected through the optical lens 922. At this time, the amount of light emitted from its outer ring is high and the light spot intensity is strong. The auxiliary lamp 962 located on the inner ring of the auxiliary light source component 96 is exposed on one side of the inner ring mounting groove 923 (the position is relatively off-center), and the light source is projected through the optical lens 922. At this time, the amount of light emitted from its outer ring is average and the light spot intensity is average.

[0058] For details, please refer to the following: Figure 10 When the optical component 92 rotates 30 degrees, the auxiliary lamp 962 located in the inner ring of the auxiliary light source component 96 is exposed to the center of the inner ring mounting groove 923. The light source is projected through the optical lens 922. At this time, the amount of light emitted from the inner ring is large and the light spot intensity is strong. The auxiliary lamp 962 located in the outer ring of the auxiliary light source component 96 is blocked by the partition between the adjacent mounting grooves 923. At this time, the amount of light emitted is small and the light spot intensity is weak.

[0059] When the optical component 92 is driven to rotate, its emission angle (beam angle) and luminous flux (light intensity) are affected by the mounting bracket 921 and the optical lens 922, realizing a dynamic visual effect of the light spot from focused light to diffused light and from bright light to dark.

[0060] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
