The present application claims priority from Chinese Application No. CN 202211693843.5 filed on Dec. 28, 2022, all of which are hereby incorporated herein by reference.
The present disclosure relates to the technical field of stage light fixtures, and more particularly, relates to an improved stage light fixture having a light effect elements server.
As a kind of stage illuminating equipment, the stage light fixture is required to simultaneous possess illuminating and lighting atmosphere creation functions. Consequently, various types and numbers of effect sheets for generating rich and colorful light effects are required for the stage light fixture to meet users' demands.
However, different kinds of effect sheets of the stage light fixture are commonly carried by different driving mechanisms respectively, the driving mechanisms each carried the same kind effect sheets are usually arranged in sequence in the light head along the light path, and the effect sheets are switched in or out at the direction perpendicular to the light path by the driving mechanisms. In such configuration, although the effect sheets are modularized according to different types, the respective driving mechanisms will still occupy space at the direction of the light path when effect sheets thereon are not used, causing extraordinarily compact structures inside the light head, which is thus not facilitate miniaturization design of the stage light fixture.
The present disclosure provides an improved stage light fixture having a light effect elements server, which can achieve that the driving mechanisms for driving the effect sheets to move may merely occupy space in the direction of the light path when in use, and may be withdrawn from the light path when out of use, thereby saving space in the direction of the light path.
According to the present disclosure, the stage light fixture includes a light source arranged in a light head for generating a light beam, a plurality of effect sheets allowing the light beam to generate light effects, at least one light effect elements server for accommodating the effect sheets, and at least one driving mechanism, which is configured to extract at least one of the effect sheets to move between the respective light effect elements server and the light beam, and is able to keep the same effect sheet in the light beam.
According to the stage light fixture in the present disclosure, the plurality of effect sheets are accommodated or received in the light effect elements server, when certain effect sheet needs to be used, such effect sheet can be extracted from the light effect elements server by the driving mechanism, and be moved to the light path to let the light beam generate light effects. While the effect sheet is out of need, it will be withdrawn back to the light effect elements server by the driving mechanism. In this way, the moving mechanism may not always occupy the space in the direction of the light path, making the space in the light head not in full use, but only temporarily occupy the space in the direction of the light path when the effect sheet is moved to the light path, the space thus can be fully utilized according to the present disclosure. Compared with the traditional technology, a greater number and types of effect sheets can be arranged in the light fixture, and even one moving mechanism can be shared by a plurality of light effect elements servers to further save space, all of which cannot be achieved by any existing stage light fixtures.
As manipulators can imitate some actions of human hands and arms to grasp and carry objects or operate tools according to set procedures, with much flexible operation, the moving mechanism according to the present disclosure may be designed in form of a manipulator.
In order to let the extracted light effect switch in or out of the light path, the moving mechanism specifically includes a transverse driving unit for driving the extracted effect sheet to move in a direction perpendicular to the light path.
Specifically, the transverse driving unit in the present disclosure may include two connecting rods with one end thereof pivotally connected to each other, and a telescopic rod with two ends thereof respectively connected to the other end of each connecting rod. With stretching and retracting the telescopic rod, the angle of the two connecting rods thus can be changed to increase or decrease the overall length of the two connecting rods, thereby enabling the effect sheet to move in the direction perpendicular to the light path.
According to the present disclosure, the effect sheet is fixed to the moving mechanism by magnetic force in a way that the moving mechanism is provided with a magnetic unit and the effect sheets are made of magnetic material or have a magnet, so that when the moving mechanism approaches the required effect sheet, the effect sheet will be magnetically attracted from the light effect elements server and be fixed to the driving mechanism, in such an easy way, the required effect sheet is extracted from the server completely. On the other hand, when the effect sheet is withdrawn back to the light effect elements server by the driving mechanism, the effect sheet can be separated from the moving mechanism with the magnetism therebetween lost, or the effect sheets can be forcibly separated from the moving mechanism once the effect sheet is fixed to the light effect elements server.
The moving mechanism has a clamping unit for clamping and fixing the effect sheet according to one embodiment of the present disclosure. In such configuration, when it is convenient to be clamped, the effect sheet thus can be easily extracted and withdrawn by the clamping unit.
For the situation that the effect sheets themselves are not convenient to be clamped, each of the effect sheets is received in the light effect elements server via a mounting base, and the effect sheet thus is moved with the mounting base by the driving mechanism. Since effect sheets are generally not convenient to be directly mounted, fixed, taken or placed. It thus facilitates the effect sheets being extracted and withdrawn from the server by the driving mechanism, in such way that the effect sheets are received in the light effect elements server 300 with being arranged on the respective mounting base.
In order to make the light spots projected by the stage light fixture to generate rotary effects, the moving mechanism is further provided with a rotary-driving unit for driving the effect sheet on the moving mechanism to rotate, thus achieving more brilliant stage effects.
Specifically, the rotary-driving unit includes a rotary-driving motor and a rotary-driving gear connected to a driving shaft of the rotary-driving motor. Correspondingly, the effect sheet is arranged on amounting base which includes a rotary base and a fixed base pivotally connected to each other. The fixed base is used for mounting and fixing the rotary base, such as the server and the driving mechanism, and the rotary base is used for mounting the effect sheet and can be driven to rotate by the rotary-driving gear. The rotary-driving gear can be directly or indirectly engaged with the rotary base to drive the rotary base to rotate according to any known methods.
In a bid to drive the effect sheet to move in the direction of the light path to change the divergence angle of the light beam or generate a special light effect, the moving mechanism may have a longitudinal driving unit for driving the effect sheet to move in the direction of the light path.
According to one embodiment of the disclosure, the longitudinal driving unit includes a sawtooth track, a gear engaged with the sawtooth track, and a longitudinal driving motor with a pivot shaft thereof connected to the gear, and the moving mechanism moves in the direction of the light path with the cooperation of the gear and the sawtooth track. Particularly, the sawtooth track is fixed, and the longitudinal driving motor, the gear and the moving mechanism move as a whole.
In the present disclosure, the light effect elements server includes a plurality of mounting parts fixed to a housing of the light head, which are configured to fix the effect sheets in a pluggable way. In such way, the light effect elements server makes use of the inner side wall of the housing to directly fix the effect sheets, without any additionally components for fixing the effect sheets.
According to the present disclosure, the effect sheets include one or more of a light shading sheet, a light dimming sheet, a light shaping sheet, an aperture, a gobo, an optical filter, a color filter, a frosting lens, a prism, a focusing lens, or a magnifying lens. The light shading sheet enables the light spot to light up and extinguish quickly, the light dimming sheet can adjust the brightness of the light spot, the light shaping sheet can change the shape of the light spot, the aperture can adjust the diameter of the light beam, the gobo enables the light spot to form a special shape, the optical filter can filter light of specific wavelengths, the color filter enables the light spot to have a specific color, the frosting lens can make the light spot more homogeneous, the prism enables the light beam to be split, the focusing lens can adjust the clarity of the light spot, and the magnifying lens can adjust the size of the light spot.
Since different types of effect sheets have different structures, it is more convenient to receive the effect sheets 200 in the different light effect elements server 300 according to types thereof. Therefore, the effect sheets accommodated in each of the light effect elements server are especially of the same type.
To simplify the design of the driving mechanism, each of the light effect elements server is respectively provided with one the driving mechanism. That is, each moving mechanism only moves only the effect sheets in the same light effect elements server, facilitating simplified design of the driving mechanism.
According to the present disclosure the light effect elements server may further provided with a screening mechanism. The light effect elements server correspondingly has a position for the effect sheet waiting to be extracted or withdrawn by the driving mechanism. The screening mechanism is configured to move the corresponding effect sheet of the light effect elements server to the position to be extracted or away from the position to be withdrawn. With such configuration, the screening mechanism thus can move the effect sheet in the light effect elements server, it is advantage for the effect sheet to be extracted from the server or withdrawn back to the server.
The light fixture may be also provided with a support arm for supporting the light head to rotate and a case for supporting the support arm to rotate. Therefore, the light head can be rotated in two dimensions to project the light beam of the light source at any angles.
The accompanying drawings are for exemplary illustration only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, some parts in the accompanying drawings may be omitted, enlarged or reduced, and they do not represent the size of the actual product; for those skilled in the art, it is understandable that certain well-known structures and descriptions thereof in the drawings may be omitted. The positional relationship described in the drawings is only for exemplary illustration, and should not be construed as limitations on this patent.
Referring to
According to the embodiment, different effect sheets 200 are accommodated in the light effect elements server 300, when certain effect sheet 200 needs to be used, such effect sheet 200 can be taken out from the light effect elements server 300 by the moving mechanism 400, and be moved to the light path to allow the light beam to generate light effects. While when the effect sheet 200 does not need to be used, it can be withdrawn back to the light effect elements server 300 by the moving mechanism 400. In this way, the moving mechanism 400 will not always occupy the space in the direction of the light path, making the space in the light head not in full use, but only temporarily occupy the space in the direction of the light path when the effect sheet 200 is moved to the light path, the space thus can be fully utilized. Compared with the traditional technology, a greater number and types of effect sheets 200 can be arranged, and even one moving mechanism 400 can be shared by a plurality of light effect elements servers 300 to further save space, all of such advantages cannot be achieved by the existing stage light fixtures.
The moving mechanism 400 may be designed in form of a manipulator, which can imitate some actions of human hands and arms to grasp and carry objects or operate tools according to set procedures, with flexible operation.
With regards to
As
The telescoping rod 412 may be a telescoping motor or a hydraulic rod.
In order to extract and fix the effect sheet 200, the moving mechanism 400 includes a magnetic unit for fixing the effect sheet 200, the effect sheets 200 correspondingly are made of magnetic material or have a magnet. The effect sheet 200 thus is magnetically fixed to the moving mechanism 400 in such embodiment. When the moving mechanism 400 approaches the required effect sheet 200, the effect sheet 200 will be magnetically attracted from the server and be fixed to the moving mechanism 400, thus being completely extracted from the light effect elements server 300. While when the effect sheet 200 is withdrawn back to the light effect elements server 300 by the moving mechanism 400, the effect sheet 200 can be separated from the moving mechanism 400 with the magnetism therebetween lost, or the effect sheet 200 can be forcibly separated from the moving mechanism 400 once the effect sheet 200 is fixed to the light effect elements server 300.
According to one embodiment, the magnetic unit is arranged at the end of one of the connecting rods 411 for fixing the effect sheet 200 by magnetic force.
The magnetic unit may be an electro-magnet chuck which is magnetic when powered on and nonmagnetic when powered off, or may be a magnetic base which is controlled by a switch to become magnetic or nonmagnetic.
The moving mechanism 400 further has a clamping unit 420 for clamping and fixing the effect sheet 200. When the effect sheets 200 are convenient to be clamped, the effect sheet 200 can be easily extracted or withdrawn by the clamping unit 420.
In the embodiment shown in
For the situation that the effect sheets 200 themselves are not convenient to be clamped, each of the effect sheets 200 is accommodated in the light effect elements server 300 via a mounting base 210, the effect sheet 200 thus is moved with the mounting base 210 by means of the moving mechanism 400. In such configuration, the effect sheets are received in the light effect elements server 300 with being arranged on the respective mounting base 210, which facilitates being extracted and withdrawn by the moving mechanism 400, as effect sheets are generally not convenient to be directly mounted, fixed and clamped.
With reference to
However, it is conceivable that the effect sheet 200 can be directly driven to rotate by the rotary-driving unit 430, and can also be indirectly driven to rotate with rotation of the mounting base 210 of the effect sheet 200 by the rotary-driving unit 430. It is also contemplated that the driving mode of the rotary-driving unit 430 can be a direct engagement way, and can also be an indirect engagement way via a synchronous belt or a transition gear.
In this case, the effect sheet 200 may be a prism or a gobo.
Specifically, according to one embodiment, the rotary-driving unit 430 includes a rotary-driving motor 431 and a rotary-driving gear 432 connected to a driving shaft of the rotary-driving motor 431. The effect sheet 200 is arranged on the mounting base 210 which includes a rotary base 211 and a fixed base 212 rotatably connected to each other. The fixed base 212 is used for mounting and fixing the rotary base 211, and the rotary base 211 is used for mounting the effect sheet 200 and can rotate driven by the rotary-driving gear 432. Notably, the rotary-driving gear 432 can be directly or indirectly engaged with the rotary base 211 to drive the rotary base 211 to rotate in any known methods.
The rotary-driving motor 431 is fixed to the one end of one connecting rod 411, and the rotary-driving gear 432 is connected to the driving shaft of the rotary-driving motor 431.
Additionally or alternatively, according to some embodiments, the moving mechanism 400 includes a longitudinal driving unit 440 for driving the effect sheet 200 to move in the direction of the light path. In such way, divergence angle of the light beam can be changed or special light effects can be generated, with the effect sheet 200 moving in the direction of the light path by means of the longitudinal driving unit 440.
In this case, the effect sheet 200 may be a focusing lens or a magnifying lens.
It should be noted that, the longitudinal driving unit 440 can individually move the effect sheet 200 in the direction of the light path, namely, one end of the moving mechanism 400 is fixed and the other end of the moving mechanism 400 is moved with the moving mechanism 400, or the whole moving mechanism 400 can be moved together with the longitudinal driving unit 440, namely, both ends of the moving mechanism 400 are moved together.
Referring back to
Preferably, both the longitudinal driving motor and the gear are accommodated in a receiving unit 442 to avoid interference with circuits in the light head 100.
Referring to
That is to say, a part of the housing 120 is used as a part of the light effect elements server 300 for the mounting parts 310. Each effect sheet 200 is mounted on the respective mounting base 210 and the mounting base 210 is fixed to the respective mounting part 310 in a pluggable way via a plug-in sheet 213 connected to the respective fixed base 212 of the mounting base 210.
In other embodiments, the light effect elements server 300 may be a separate box, frame, or spiral track.
According to the present disclosure, the effect sheet 200 may include one or more of a light shading sheet, a light dimming sheet, a light shaping sheet, an aperture, a gobo, an optical filter, a color filter, a frosting lens, a prism, a focusing lens, or a magnifying lens. The light shading sheet enables the light spot to light up and extinguish quickly, the light dimming sheet can adjust the brightness of the light spot, the light shaping sheet can change the shape of the light spot, the aperture can adjust the diameter of the light beam, the gobo enables the light spot to form a special shape, the optical filter can filter light of specific wavelengths, the color filter enables the light spot to have a specific color, the frosting lens makes the light spot more homogeneous, the prism enables the light beam to be split, the focusing lens can adjust the clarity of the light spot, and the magnifying lens can adjust the size of the light spot.
Additionally, a plurality of driving mechanisms 400 can be provided to simultaneously move various effect sheets 200 to switch in the light path, The various effect sheets 200 thus cooperate with each other to generate more complicated light rays. It can be noted that, the various effect sheets 200 can be of the same type, for example, all being the light shaping sheet, the optical filter, the gobo, or the prism, or can be different, for example, being the gobo, the optical filter, the color filter, the frosting lens, the prism, the focusing lens, and a magnifying lens, respectively.
However, it is preferable that all the effect sheets 200 accommodated in each of the light effect elements server 300 are of the same type. Since different types of effect sheets 200 have different structures, it is more convenient to store the effect sheets 200 respectively in the different light effect elements server 300 according to types thereof.
In order to simplify the design of the moving mechanism 400, it is configured that each of the light effect elements server 300 is respectively provided with one moving mechanism 400. That is, each moving mechanism 400 only moves the effect sheets 200 in the same light effect elements server 300, thus facilitating simplified design of the moving mechanism 400.
However, in other embodiments, it can be configured that each of the light effect elements servers 300 may provide with various driving mechanisms 400 respectively, or various light effect elements servers 300 are arranged one moving mechanism 400.
According to some embodiments, as shown in
Specifically, the screening mechanism 320 may includes a drive roller 321 and a transmission belt 322. The effect sheets 200 are moveably mounted on the transmission belt 322 via the mounting base 210, especially in a pluggable way. It is operable in a way that the transmission belt 322 is conveyed with rotation of the drive roller 321, which in turn drives the effect sheets 200 to move. Once the required effect sheet is moved to the position 330, the moving mechanism 400 will extract the effect sheet to lie in the light path to produce light effects. After completion of use, the effect sheet is withdrawn to the position 330 by the moving mechanism 400 and finally replaced to original place in the light effect elements server 300 by means of the transmission belt 322.
