Description

Technical Field

[0001] The present invention relates to the technical field of stage lights, and more particularly to a light path with effect area partitions and a stage light having the same. Background Art

[0002] In the field of stage lighting technology, dynamic effect discs are added to enrich stage effects, and the most commonly used are rotating effect discs and compound effect discs. Rotating effect discs usually rotate a single effect disc to produce dynamic stage effects, while compound effect discs superimpose two effect discs with different rotation states to form a gorgeous stage light effect. However, the common point between the two is that the only effect area formed covers the entire light spot and rotates and changes as a whole.

[0003] Although the traditional effect disk can switch different effect pieces to achieve different light spot effects, with the increasing demand for effects in the market, a stage light with richer light spot change effects will be favored by the market. Summary of the invention

[0004] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide a light path with effect area partitions and a stage light having the same, so as to solve the problem of further enriching the effect of stage light spot changes.

[0005] The technical solution adopted by the present invention is: a light path with effect area partitions, including a light source component and an effect component; the light source component includes a light source and a light collector, the light collector forms a light path with the light emitted by the light source and converges it to a focus; the effect component includes a plurality of effect sheets that are at least partially located in the light path at the same time, the effect sheets are located at the focus or close to the focus, the effect sheets are staggered with each other in the direction of the light path, and at least one of the effect sheets can rotate, so that the light path projects a light spot with multiple effect area partitions.

[0006] By staggering the effect sheets in the direction of the light path, the effect areas formed by the light passing through the effect sheets present a staggered distribution effect in the final projected light spot, that is, multiple independent effect areas are formed in the same light spot, which can be completely separated or partially overlapped, and the effect area formed by the rotating effect sheet is also rotating, so that effect areas with different motion states appear in the same light spot, and the light spot effect formed is richer.

[0007] Furthermore, the effect sheet is circular, and the rotation center of the effect sheet coincides with the center of the circle, or the rotation center of the effect sheet is set away from the center of the circle. When the rotation center of the effect sheet coincides with the center of the circle, the size of the effect area formed by the effect sheet remains unchanged when the effect sheet rotates; and when the rotation center of the effect sheet is set away from the center of the circle, the size of the effect area formed by the effect sheet changes when the effect sheet rotates.

[0008] Furthermore, the effect sheets are completely staggered in the direction of the light path, and the projections of each effect sheet are completely separated, so that the effect areas produced do not affect each other, which is more conducive to the lighting engineer's control of the stage lighting effect.

[0009] Further, the effect sheet is at least one of a pattern sheet or a color sheet, wherein the color sheet has at least two color regions. When the effect sheets are all patterns, the light spot formed has multiple pattern effect regions; when the effect sheets are all color sheets and have at least two color regions, the light spot formed has at least two color regions of different colors; when the effect sheet is a combination of a pattern sheet and a color sheet, the light spot presented has both a pattern effect region and a color effect region.

[0010] Furthermore, the rotation rate of at least one rotatable effect sheet is different from the rotation rate of other rotatable effect sheets, so that in the same light spot, the rotation rate of at least one effect area is different from the rates of other rotating effect areas, which can achieve richer light spot effects.

[0011] Furthermore, the rotation drives of at least two rotatable effect sheets are linked to each other, forming at least two mutually linked effect areas, and the structure of the rotation drive design can also be simple and light.

[0012] Furthermore, at least two rotatable effect sheets rotate in the same direction, so that the formed light spot has at least two effect areas with the same rotation direction.

[0013] Furthermore, it also includes a driving mechanism for driving the effect sheet to cut into and out of the light path, and the driving mechanism for the effect sheet to cut into and out of the light path is shared. The effect sheet can be cut into or out of the light path at the same time through the shared driving mechanism, and the structure of the driving mechanism can also be simpler.

[0014] Furthermore, the rotation direction of at least one rotatable effect sheet is opposite to the rotation direction of other rotatable effect sheets, so that in the same light spot, the rotation direction of at least one effect area is different from the rotation direction of other effect areas, further enriching the stage light effect and creating a visual contrast for the audience.

[0015] Furthermore, among the rotatable effect sheets, at least two of the rotatable effect sheets are driven to rotate independently of each other. Such a configuration can more flexibly control the rotation of the effect sheet, and can more conveniently design at least two effect sheets rotating at different speeds, or at least two effect sheets rotating in different directions, or at least two effect sheets rotating at different speeds and in different directions.

[0016] Furthermore, it also includes a driving mechanism for driving the effect piece to cut into and out of the light path, and the driving mechanisms for the effect piece to cut into and out of the light path are independent of each other. Each of the effect pieces adopts a driving mechanism that is independent of each other, and uses their own driving mechanism to independently control each of the effect pieces to cut into and out of the light path, as well as the position of the light path, so that the control is more flexible and convenient, and the lighting effect is more colorful and varied.

[0017] Furthermore, the effect assembly includes a fixed plate with a light-through hole, a plurality of effect sheets arranged around the light-through hole, a transmission mechanism for driving at least one of the effect sheets to rotate, and a motor for driving the transmission mechanism, the light path passes through the light-through hole, the effect sheet at least partially cuts into the light-through hole, the transmission mechanism is connected to the effect sheet, and the motor drives the effect sheet to rotate through the transmission mechanism. By arranging the effect sheets on the same fixed plate, the effect of simultaneously cutting into or out of the light path of a plurality of effect sheets located in the light path is achieved through a common driving mechanism.

[0018] Furthermore, at least two of the effect pieces are rotatable, and the transmission mechanism includes a linkage member and a driven gear fixed on the rotatable effect piece, and the rotatable effect piece is driven to rotate by the same linkage member. Such a design can realize the linkage rotation of at least two effect pieces.

[0019] Furthermore, the linkage member includes a toothed ring surrounding the light-through hole, the inner side of the toothed ring has saw teeth, and the driven gear is arranged within the range surrounded by the toothed ring and driven by the toothed ring. Such a design realizes the linkage effect of the effect piece and also makes the structure more compact, thereby reducing the volume of the effect component.

[0020] Furthermore, the fixing plate is surrounded by a plurality of light holes, each of which is surrounded by a plurality of effect sheets, at least one of which can be driven to rotate by the toothed ring, the outer side of which has saw teeth, and the plurality of toothed rings are driven by a driving gear in the middle. Because only one light hole cuts into the light path when the stage light is running, it is only necessary to control the rotation of the toothed ring that cuts into the light path as required, and even if the other toothed rings rotate accordingly, it will not affect the effect of the projected light spot, and such a design structure is simple and easy to control.

[0021] Furthermore, the transmission mechanism further comprises a transition gear disposed between the gear ring and the driven gear, the transition gear meshing with the gear ring and the driven gear at the same time. By disposing transition gears of different numbers and different sawtooth amounts between the gear ring and the driven gear, the effect piece can realize forward or reverse rotation and different rotation speeds.

[0022] Furthermore, it also includes a mounting seat for mounting the effect sheet, the transition gear and the gear ring, the fixing plate is surrounded by a plurality of through holes, the mounting seat is embedded in the through holes to be mounted on the fixing plate, the gear ring is sleeved on the edge of the mounting seat, the effect sheet and the transition gear are both arranged on the mounting seat, and the light hole is arranged in the middle of the mounting seat. By mounting the effect sheet, the transition gear and the gear ring together on the mounting seat, different effect sheet combinations can be disassembled and replaced as a whole, which is convenient for operation.

[0023] Furthermore, it also includes a driving mechanism for driving the fixing plate to rotate so that the effect sheet cuts into or out of the light path. By setting the driving mechanism to drive the fixing plate to rotate, the original combination of the effect sheet is cut out of the light path, and other combinations of the effect sheet are switched, so that the stage light can project a richer light spot effect.

[0033] By staggering the effect sheets 110 in the direction of the light path, the effect areas formed by the light passing through the effect sheets 110 present a staggered distribution effect in the finally projected light spot, that is, multiple independent effect areas are formed in the same light spot, which can be completely separated or partially overlapped, and the effect area formed by the rotating effect sheet 110 is also rotating, so that effect areas with different motion states appear in the same light spot, and the light spot effect formed is richer.

[0035] Preferably, the effect sheets 110 located in the light path can all rotate, presenting a light effect in which a plurality of effect areas in one light spot rotate simultaneously, thereby achieving a colorful stage effect.

[0036] Preferably, the effect sheets 110 are staggered on the light path, but partially overlap each other, so that while realizing multiple effect area partitions, the projected parts of the effect sheets 110 are superimposed, and the overlapping parts form new superimposed effect areas, further enriching the stage effects.

[0037] like Figures 2 to 3 As shown, in a preferred embodiment of the present invention, the effect sheet 110 is circular, and the rotation center of the effect sheet 110 coincides with its circle center, or the rotation center of the effect sheet 110 is set away from its circle center.

Preferably, in this embodiment, the rotation center of the effect sheet 110 coincides with its circle center.

The effect sheets 110 are completely staggered, and the projections of each effect sheet 110 are completely separated, and the effect areas generated do not affect each other, which is more conducive to the lighting engineer's control of the stage lighting effect.

[0039] In a preferred embodiment of the present invention, the effect sheet 110 is at least one of a pattern sheet or a color sheet, wherein the color sheet has at least two color regions.

In the same light spot, the rotation rate of at least one effect area is different from the rates of other rotating effect areas, so that richer light spot effects can be achieved.

[0041] In a preferred embodiment of the present invention, the rotation drives of at least two rotatable effect sheets 110 are linked to each other, forming at least two mutually linked effect areas, and the structure of the rotation drive design can also be simple and light.

[0044] In a preferred embodiment of the present invention, the rotation direction of at least one rotatable effect sheet 110 is opposite to the rotation direction of other rotatable effect sheets 110. In the same light spot, the rotation direction of at least one effect area is different from the rotation direction of other effect areas, further enriching the stage light effect and creating a visual contrast for the audience.

[0045] In a preferred embodiment of the present invention, among the rotatable effect sheets 110, the rotation drives of at least two rotatable effect sheets 110 are independent of each other. Such a setting can more flexibly control the rotation of the effect sheet 110, and can more conveniently design at least two rotating effect sheets 110 with different speeds, or at least two effect sheets 110 with different rotation directions, or at least two effect sheets 110 with different speeds and rotation directions.

The light path passes through the light-through hole 130, the effect sheet 110 at least partially cuts into the light-through hole 130, the transmission mechanism 140 is connected to the effect sheet 110, and the motor drives the effect sheet 110 to rotate through the transmission mechanism 140. By arranging the effect sheets 110 on the same fixed plate 120, the effect of simultaneously cutting into or out of the light path of a plurality of effect sheets 110 located in the light path through a common motor is achieved.

The outer side of the toothed ring 142 has saw teeth, and the plurality of toothed rings 142 are driven by a driving gear 143 located in the middle. Because only one light hole 130 cuts into the light path when the stage light is running, it is only necessary to control the rotation of the toothed ring 142 that cuts into the light path as required, and even if the other toothed rings 142 rotate accordingly, it will not affect the effect of the projected light spot. Such a design structure is simple and easy to control.

[0063] In a preferred embodiment of the present invention, a driving mechanism 170 is further included to drive the fixing plate 120 to rotate so that the effect sheet 110 cuts into or out of the light path. By setting the driving mechanism 170 to drive the fixing plate 120 to rotate, the original combination of the effect sheet 110 is cut out of the light path, and other combinations of the effect sheet 110 are switched, so that the stage light can project a richer light spot effect.
