Description

Technical Field

[0001] The present invention relates to the technical field of stage lamps, and in particular to a very small CMY component. Background Art

[0002] CMY components are widely used in stage lighting, and related technologies and applications are mature. Related improvements generally remain in the areas of structural versatility or CMY color effects.

[0003] For example, the patent document with publication number CN209399305U discloses a universal CMY bracket, which solves the problem that when the number of color mixing sheets needs to be increased or decreased, the number of guide rods or the distance between adjacent guide rods needs to be adjusted accordingly, resulting in the need to make a new fixing seat each time, which is costly.

[0004] Another example is the patent document with publication number CN107842814A, which describes a multi-layer CMY color mixing system and optical path system. The problem it solves is that different color mixing effects are sometimes required during stage performances. This requires multiple stage lights with different color mixing effects to achieve this, which brings great inconvenience to stage art design.

[0005] The CMY components in the above two patent documents are the most widely used structural design. It can be seen from the documents and drawings that one end of each layer of color mixing film is fixed on the double guide rods, and the double guide rods are located on both sides of the belt; when there are multiple layers of color mixing films, the structural design of each layer is the same, and the double guide rods at the fixed end of each layer of color mixing film are arranged side by side.

[0006] With the development of the stage lighting industry and the increasing use of LED light sources, miniaturization of lamps has become a trend. However, due to its special structural requirements, the volume occupied by CMY components is relatively fixed, which also affects the design and size of the optical system. Moreover, as the demand for color mixing for lighting effects increases, the number of CMY color mixing layers increases, and the volume of the entire CMY component increases, making it impossible to reduce the size of the lamp. The solution currently used for small stage lamps is simply to reduce the size of all components in the same proportion to reduce the volume of CMY.

[0007] So far, we have not found any technological breakthroughs or innovations in reducing the size of CMY components from the perspective of CMY component structure design itself. Summary of the Invention

[0008] The object of the present invention is to provide an optimized and extremely small CMY component, so as to reduce the volume of the CMY component from the perspective of structural design.

[0009] To achieve the above object, the present invention adopts the following technical solutions:

[0010] An optimized, extremely small CMY assembly comprises a CMY fixing frame, a multi-layer color mixing unit fixed to the CMY fixing frame, and at least one pair of guide rod brackets; each layer of the color mixing unit comprises two motion units, each motion unit comprising a CMY positioning block, a CMY color mixing sheet fixed to the CMY positioning block, and a drive device for driving the CMY positioning block to move; the guide rod brackets are arranged relative to each other on the CMY fixing frame, each pair of the guide rod brackets is jointly fixed with at least two guide rods, and the guide rod brackets include at least two through holes for a single guide rod to pass through, characterized in that a CMY positioning block is respectively fixed at each end of the CMY color mixing sheet, and each CMY positioning block is passed through by a guide rod.

[0011] As a preferred technical solution, the two through holes on the guide rod bracket are distributed at different heights and are not in the same vertical plane.

[0012] Furthermore, both ends of the single guide rod are respectively fixed in through holes at the same height.

[0013] As a preferred technical solution, the driving device includes a motor, a belt, and a driving gear, and each pair of the guide rod brackets is arranged between the two driving gears in the same driving direction.

[0014] Furthermore, one of the two guide rods on the guide rod bracket is located in the middle of the belt, and the other is located outside the belt.

[0015] Furthermore, the guide rod bracket is also provided with a clearance hole for avoiding the driving gear.

[0016] Specifically, the guide rod bracket is divided into guide rod bracket one, guide rod bracket two, guide rod bracket three, and guide rod bracket four. The guide rod bracket one and the guide rod bracket two are in a mirror relationship and are arranged opposite to each other; the guide rod bracket three and the guide rod bracket four are in a mirror relationship and are arranged opposite to each other.

[0017] Furthermore, the CMY positioning block includes a locking portion for fixing the CMY color mixing sheet and a through portion for fixing the guide rod.

[0018] Specifically, the CMY positioning block is divided into CMY positioning block A, CMY positioning block B, CMY positioning block a, and CMY positioning block b. The CMY positioning block A and CMY positioning block B are in a mirror relationship, and the CMY positioning block a and CMY positioning block b are in a mirror relationship; the CMY positioning block A and CMY positioning block B also include a belt groove and a bending part.

[0019] Specifically, it also includes a travel switch for limiting the CMY color mixing film, and the travel switch is located at the edge of the CMY fixing frame.

[0020] Compared with the existing technology, the beneficial effects of this technical solution are:

[0021] 1- The two guide rods on the guide rod bracket are located in the middle of the belt and the other is located on the outside of the belt and close to the CMY color mixing film. This design is significantly narrower than the traditional design with two guide rods distributed on the outside of the belt.

[0022] The two through holes on the 2-guide rod bracket are distributed at different heights and are not in the same vertical plane. This design allows the CMY positioning blocks that occupy the most space in the two adjacent layers of color mixing films to be staggered. Compared with the conventional design of arranging two guide rods in parallel at the fixed end of each layer of color mixing films, this technical solution is much smaller in height than the traditional design.

[0023] 3- There is a CMY positioning block fixed on each end of the CMY color mixing film. This double-end support design is significantly better in terms of CMY movement stability than the traditional CMY color mixing film single-side support design. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] As attached Figure 1-3As shown, an optimized small-sized CMY component comprises a CMY fixing frame (10), two layers of color mixing units (11) fixed on the CMY fixing frame (10), and two pairs of guide rod brackets (20); each layer of color mixing unit (11) comprises two motion units, each motion unit comprises a CMY positioning block (50), a CMY color mixing sheet (30) fixed on the CMY positioning block (50), and a driving device for driving the CMY positioning block (50) to move; the two pairs of guide rod brackets (20) are distributed on the CMY fixing frame (10) and the CMY color mixing sheet (30) fixed on the CMY positioning block (50). On both sides of the frame (10), each pair of guide rod brackets (20) are arranged opposite to each other on the CMY fixing frame (10), and each pair of guide rod brackets (20) are commonly fixed with two guide rods (40), and each guide rod bracket (20) includes two through holes for a single guide rod to pass through. For the above technical details, please refer to the patent document "A multi-layer CMY color mixing system and optical path system" with publication number CN107842814A and the patent document "A universal CMY bracket" with publication number CN209399305U.

[0038] As a preferred embodiment, a CMY positioning block is fixed at each end of the CMY color mixing sheet (30), namely, CMY positioning block A (50) and CMY positioning block a (60), and each CMY positioning block is passed through by a guide rod (40). The beneficial effect of this embodiment is that the CMY color mixing sheet (30) adopts a single-side single guide rod (40) design, which is more convenient than

[0039] The traditional single-sided double guide rod design is significantly smaller in width, thus reducing the volume.

[0040] As a preferred embodiment, the two through holes on the guide rod bracket (20) are distributed in different heights and are not in the same vertical plane, namely, a high hole (21) and a low hole (22). On both sides of the CMY fixed frame, a pair of guide rod brackets (20) are respectively arranged opposite to each other. Each pair of guide rod brackets (20) fixes two guide rods (40) together, wherein the two ends of one guide rod (40) pass through the two high holes (21), and the two ends of the other guide rod (40) pass through the two low holes (22). The four guide rods are high, low, high, and low from left to right. The beneficial effects of this embodiment are described in detail below.

[0041] As attached Figure 6 As shown, the calculation is performed based on the mechanical dimensions of the components of the CMY assembly known in the stage lighting industry, assuming that the diameter of the guide rod is Φ = 4 mm and the single-side thickness of the CMY positioning block is H1 = 1.2 mm.

[0042] In this design, the vertical height difference of the two staggered guide rods is d1=0.5mm;

[0043] In the traditional double guide rod vertical arrangement design, the vertical height difference between the two guide rods is d2 = H1 + d (safety distance of moving parts) + H1 = 1.2 + 0.5 + 1.2 = 2.9 mm;

[0044] In summary, the height d1 of this design is 2.9-0.5=2.4mm lower than the height d2 of the traditional design. It can be seen that the height is much smaller than that of the traditional design.

[0045] As a preferred embodiment, the driving device includes a motor (71), a belt (73), and a driving gear (72). Each pair of guide rod brackets (20) is arranged between two driving gears (72) in the same driving direction. The beneficial effect of this embodiment is that, compared with the traditional double guide rod design in which the guide rod brackets (20) are located outside the driving gear, the length is significantly smaller, thereby reducing the final volume.

[0046] Specifically, the two guide rods (40) on the guide rod bracket (20) are located in the middle of the belt (73) and the other is located outside the belt (73). The beneficial effect of this embodiment is that, on the basis of reducing the volume, interference between the CMY color mixing layers is better avoided.

[0047] Specifically, the guide rod bracket (20) is further provided with an avoidance hole (23) for avoiding the driving gear (72). The beneficial effect of this embodiment is to avoid interference between the guide rod bracket (20) and the driving gear (72).

[0048] More preferably, as attached Figure 5 As shown, the guide rod bracket (20) is divided into a guide rod bracket 1, a guide rod bracket 2, a guide rod bracket 3, and a guide rod bracket 4. The guide rod bracket 1 and the guide rod bracket 2 are in a mirror image relationship and are arranged relative to each other; the guide rod bracket 3 and the guide rod bracket 4 are in a mirror image relationship and are arranged relative to each other. The beneficial effect of this implementation scheme is that, in a relatively narrow CMY component hole, under the premise of not affecting the assembly, the guide rod bracket (20) with the best details is designed according to the different installation directions of the guide rod bracket (20) at each specific position, thereby avoiding interference between the guide rod bracket (20) and other components.

[0049] Specifically, the CMY positioning block A (50) includes a locking portion (51) for fixing the CMY color mixing sheet (30) and a through portion A (52) for penetrating the guide rod (40); the CMY positioning block a (60) includes a locking portion (51) for fixing the CMY color mixing sheet (30) and a through portion a (53) for penetrating the guide rod (40); the locking portion (51) is an oblique groove, which is used to prevent the CMY color mixing sheets from interfering with the locking portion when they move to cross each other; the through portion A (52) is a circular through hole design, and the through portion a (53) is an arc-shaped open groove design; the beneficial effect of this embodiment is that the CMY color mixing sheet (30) is fixed by the CMY positioning block A (50) and the CMY positioning block a (60), so that the stability of the CMY color mixing sheet (30) during movement is higher.

[0050] More preferably, as attached Figure 4 As shown, the CMY positioning blocks are divided into CMY positioning block A (50), CMY positioning block B, CMY positioning block a (60), and CMY positioning block b. CMY positioning block A (50) and CMY positioning block B are in a mirror image relationship, and CMY positioning block a (60) and CMY positioning block b are in a mirror image relationship. The CMY positioning block A (50) and the CMY positioning block B further include two belt grooves (54) and a bending portion (55). The two belt grooves (54) are respectively located on both sides of the through portion A (52), and one of them can be selected to be fixed to the belt according to the installation position; the bending portion (55) is located between the locking portion (51) and one of the belt grooves (54), and is used for the CMY positioning block A (50) and the CMY positioning block B to avoid the guide rod (40) of another layer of CMY color mixing layer when moving; the beneficial effect of this embodiment is that, in a relatively narrow CMY component hole, under the premise of not affecting assembly, the CMY positioning block with the best details is designed according to the different installation directions of the guide rod bracket (20) at each specific position, thereby avoiding interference between the CMY positioning block and other components.

[0051] As a preferred embodiment, it also includes a travel switch (50) for limiting the CMY color mixing sheet, and the travel switch (50) is set at the edge of the CMY fixing frame (10). The beneficial effect of this technical solution is that the travel switch (50) with a stop function is used to control the travel of the CMY color mixing sheet (30), which can eliminate the problem of the CMY color mixing sheet (30) becoming smaller due to the use of a guide rod bracket (20) set between two driving gears (72) in the same driving direction to reduce the length of the CMY component, while utilizing the redundant space in the structure.

[0052] Example 2: CMY components include three or more color mixing units

[0053] It is understandable to those skilled in the art that the increase in the number of layers of the color mixing unit does not increase the difficulty in structural design. The original color mixing structure can be obtained by superimposing and simply changing it. Moreover, this technology has been very mature in the field of traditional CMY components. For this embodiment, the same structural principle as that of the first embodiment is adopted. Figure 7 and 8 As shown, the CMY component includes a color mixing C unit layer (91), a color mixing M unit layer (92), a color mixing Y unit layer (93), and a color mixing K unit layer (94); briefly speaking, a driving gear (72), a belt (73), a guide rod bracket (20), a travel switch (80), etc. are added.

[0054] As those skilled in the art will appreciate, the height d1 calculated in Example 1 is 2.9-0.5 = 2.4 mm lower than the height d2 of the conventional design. This indicates that the greater the number of CMY color mixing unit layers, the greater the reduction in total CMY height achieved by staggered guide rod arrangement compared to the conventional design, i.e., the smaller the total CMY volume achieved with this design. This is because the height of the conventional vertical guide rod arrangement is the direct sum of the single-side thickness H1 of the CMY positioning block + d (the safety distance for the moving parts).

[0055] In the description herein, it should be understood that the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example.

[0057] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
