Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically, to a stage lamp with a micro opening and closing effect module. Background Art

[0002] The functions of stage lights are becoming more and more abundant, but the size is getting smaller and smaller, so the internal space is very compact. Stage lights usually have multiple effect modules for generating light effects. The effect modules cut into / out of the light path by rotation or translation. When the effect module is not used, it is located outside the light path as a whole and occupies the position. In other words, idle space needs to be reserved for the effect module in the stage light, which affects the compactness of the internal structure of the stage light and is not conducive to setting more effect modules. Utility Model Content

[0003] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a stage light with a micro opening and closing effect module. When the effect sheet is not used to intercept the light beam, the movement of the effect sheet is smaller and the idle space occupied is also smaller, thereby saving the internal space of the stage light.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a stage light with a miniature opening and closing effect module, including a lamp head, in which a light source for emitting a light beam and an effect module for selectively intercepting the light beam to produce light effects are arranged, the effect module includes at least 3 effect sheets arranged around the light beam and a rotating drive mechanism for driving the effect sheets to cut in / out of the light beam, one end of the effect sheet is pivotally connected, the other end swings, and has a removal position completely outside the light beam and an interference position at least partially located in the light beam.

[0005] The stage light with a micro-opening and closing effect module arranges the effect pieces of the effect module around the light beam. When the light effect of the effect module is needed, the rotating drive mechanism drives each of the effect pieces to cut into the light beam to jointly produce the light effect. When the light effect of the effect module is not needed, the light effect of the effect module can be canceled by rotating each of the effect pieces out of the light beam. Compared with all the effect pieces moving out of the light beam as a whole, each of the effect pieces rotates out of the light beam individually, and occupies less idle space, thereby saving the internal space of the stage light.

[0006] Furthermore, all the effect pieces are driven to rotate by the same rotation drive mechanism, which saves the number of drives and reduces the space occupied by the stage light.

[0007] Furthermore, a synchronous wheel is fixed to the pivotal end of the effect piece, and the rotation drive mechanism drives all the synchronous wheels simultaneously through a synchronous belt, that is, the synchronous wheel connected to the pivotal end of each effect piece is driven by the synchronous belt, so that one rotation drive mechanism drives all the effect pieces to swing.

[0008] Furthermore, it also includes a tensioning wheel for adjusting the tightness of the synchronous belt. The tensioning wheel adjusts the tightness of the synchronous belt, thereby ensuring that the synchronous belt is closely meshed with the synchronous wheel and the rotary drive mechanism to avoid step loss.

[0009] Furthermore, the pivot end of the effect sheet is fixed relative to the optical path, that is, the pivot end of the effect sheet will not move but will only rotate, so that the effect sheet can be driven by the simple-structured rotation drive mechanism.

[0010] Furthermore, the effect module also includes a substrate, the substrate is provided with a light-through hole for light beams to pass through, the effect sheet is pivotally connected to the substrate around the light-through hole, and the effect sheet is fixed to the substrate for easy assembly and disassembly of the whole.

[0011] Furthermore, it also includes a rotatable cover plate arranged opposite to the base plate, the cover plate is also provided with a light hole for light beams to pass through, the other end of the effect sheet is directly or indirectly pivoted to the cover plate, and the cover plate is driven to rotate by a rotation drive mechanism. In this way, only the cover plate needs to be driven to rotate, and all the effect sheets can be driven to swing at the same time, and the base plate and the cover plate can jointly limit the effect sheet to prevent it from shaking at will.

[0012] Furthermore, the effect sheets are located in different planes without interfering with each other, or the effect sheets are located in the same plane, so that the effect sheets can cooperate with each other and act on the light beam together.

[0013] Furthermore, the effect sheets also have a full shielding position, and the effect sheets cooperate with each other to completely intercept the light beam, that is, the light beam will all pass through the effect sheets before being emitted, and no part of the light beam will be emitted through the gaps between the effect sheets.

[0014] Furthermore, the effect sheet is a light-homogenizing sheet or a pattern sheet, and a projection pattern is arranged on the pattern sheet. The light-homogenizing sheet realizes a light-homogenizing effect, making the light beam mixed more uniformly, and the pattern sheet can realize projecting a specific pattern.

[0015] Furthermore, it also includes a support arm for supporting the rotation of the lamp head and a chassis for supporting the rotation of the support arm, so that the light beam can be projected in any direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0025] like Figures 1 to 3 The utility model provides a stage light with a micro opening and closing effect module, including a lamp head 110, wherein the lamp head 110 is provided with a light source 111 for emitting a light beam and an effect module 200 for selectively intercepting the light beam to produce a light effect, wherein the effect module 200 includes at least three effect sheets 210 arranged around the light beam and a rotating drive mechanism 220 for driving the effect sheet 210 to cut in / out of the light beam, wherein one end of the effect sheet 210 is pivotally connected and the other end swings, and the effect sheet 210 has a removal position completely outside the light beam and an interference position at least partially located in the light beam.

[0026] The stage light with a micro-opening and closing effect module arranges the effect piece 210 of the effect module 200 around the light beam. When the light effect of the effect module 200 is needed, the rotating drive mechanism 220 drives each of the effect pieces 210 to cut into the light beam to jointly produce the light effect. When the light effect of the effect module 200 is not needed, it is only necessary to rotate each of the effect pieces 210 out of the light beam to cancel the light effect of the effect module 200. Compared with all the effect pieces 210 moving out of the light beam as a whole, each of the effect pieces 210 rotates out of the light beam individually, and occupies less idle space, thereby saving the internal space of the stage light.

[0027] In this embodiment, the effect module 200 includes three effect sheets 210 arranged around the light beam.

[0028] In this embodiment, the effect sheets 210 have the same external shape, and the areas of the light beams cut into them change synchronously.

[0029] In a preferred embodiment of the present invention, all the effect sheets 210 are driven to rotate by the same rotation drive mechanism 220, which saves the number of drives and reduces the space occupied by the stage light.

[0030] In a preferred embodiment of the utility model, a synchronous wheel 221 is also fixed to the pivotal end of the effect piece 210, and the rotation drive mechanism 220 drives all the synchronous wheels 221 simultaneously through a synchronous belt 222. That is, the synchronous wheel 221 connected to the pivotal end of each effect piece 210 is driven by the synchronous belt 222, so that one rotation drive mechanism 220 drives all the effect pieces 210 to swing.

[0031] In this embodiment, the synchronous wheel 221 and the effect piece 210 are pivotally connected to the same pivot shaft 223 .

[0032] In a preferred embodiment of the utility model, a tensioning wheel 224 is further included for adjusting the tightness of the synchronous belt 222. The tensioning wheel 224 adjusts the tightness of the synchronous belt 222, thereby ensuring that the synchronous belt 222 is tightly engaged with the synchronous wheel 221 and the rotary drive mechanism 220 to avoid step loss.

[0033] In this embodiment, the position of the tensioning wheel 224 is adjustable.

[0034] In a preferred embodiment of the utility model, the pivot end of the effect sheet 210 is fixed relative to the optical path, that is, the pivot end of the effect sheet 210 does not move but only rotates, so that the effect sheet 210 can be driven by the simple rotating drive mechanism 220.

[0035] In a preferred embodiment of the utility model, the effect module 200 further includes a substrate 225, the substrate 225 is provided with a light hole for light beams to pass through, and the effect sheet 210 is pivotally connected to the substrate 225 around the light hole. The effect sheets 210 are fixed to the substrate 225 for easy assembly and disassembly.

[0036] like Figure 4 In a preferred embodiment of the utility model, a rotatable cover plate 226 is also provided opposite to the base plate 225, and the cover plate 226 is also provided with a light hole for light beams to pass through. The other end of the effect sheet 210 is directly or indirectly pivoted to the cover plate 226, and the cover plate 226 is driven to rotate by the rotation drive mechanism 220. In this way, only the cover plate 226 is driven to rotate, and all the effect sheets 210 can be driven to swing at the same time, and the base plate 225 and the cover plate 226 can jointly limit the effect sheet 210 to prevent it from shaking at will.

[0037] In this embodiment, the cover plate 226 is provided with driving teeth 227 , and the rotation driving mechanism 220 is engaged with the driving teeth 227 to drive the cover plate 226 to rotate.

[0038] In this embodiment, the other end of the effect sheet 210 is pivotally connected to the cover plate 226 via a connecting rod 228 .

[0039] In a preferred embodiment of the present invention, the effect sheets 210 are located in different planes and do not interfere with each other (eg Figure 6 ), or the effect sheets 210 are located in the same plane. This facilitates the mutual cooperation of the effect sheets 210 to act on the light beam together.

[0040] In a preferred embodiment of the utility model, the effect sheet 210 also has a full shielding position, and the effect sheets 210 cooperate with each other to completely intercept the light beam. That is, the light beam will all pass through the effect sheet 210 before being emitted, and no part of the light beam will be emitted through the gaps between the effect sheets 210. The full shielding position is an extreme case of the interference position.

[0041] In other embodiments, the pivotal ends of the effect sheets 210 may be located in the same plane. When the effect sheets 210 move to a stacked state, the free end of each effect sheet 210 is located below the free end of the previous effect sheet 210 in the circumferential direction of the light beam. However, this cannot achieve a fully shielded position.

[0042] In a preferred embodiment of the utility model, the effect sheet 210 is a light-homogenizing sheet or a pattern sheet, and a projection pattern is arranged on the pattern sheet. The light-homogenizing sheet realizes a light-homogenizing effect to make the light beam mixed more uniformly, and the pattern sheet can realize projecting a specific pattern.

[0043] When the effect sheet 210 is a light homogenizing sheet, compared with the single light homogenizing sheet in the prior art that cuts into the light beam from one side, the multiple effect sheets 210 in the present application cut into the light beam from multiple positions, so that the light homogenizing effect can be replaced to achieve linear changes, making the light beam mixing more uniform; when the effect sheet 210 is a pattern sheet, a gradually opening and closing animation effect can be achieved, which is impossible for ordinary pattern sheets to achieve.

[0044] like Figure 5 In a preferred embodiment of the utility model, a support arm 120 for supporting the rotation of the lamp head 110 and a chassis 130 for supporting the rotation of the support arm 120 are also included. Thus, the light beam can be projected in any direction.

[0045] The lamp head 110 is also provided with a light source 111, a focusing lens group 112, a magnifying lens group 113 and a light output lens group 114 in sequence. When the effect sheet 210 is a light homogenizing sheet, the effect module 200 is located between the focusing lens group 112 and the magnifying lens group 113 (such as Figure 6 ), when the effect sheet 210 is a pattern sheet, the effect module 200 is located between the focusing lens group 112 and the light source 111, preferably near the focus of the light source 111, so as to facilitate imaging.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
