[0036] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0037] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.
[0038] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0039] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.
[0040] Figure 1 Schematic diagram of the imaging principle of stage lights. The light emitted by the light source 10 passes through the cutter 20 to form a light source pattern under the action of the cutter 20, and then is projected through the lens group 30 to form an image. Figure 1 In the figure, three lenses 31 are merely schematically used to form the lens group 30 (ie, the optical lens focusing and zooming system), and no limitation is imposed on the lens group 30 .
[0041] Figure 2 Cut the beam pattern for the existing cutter. Figure 2 It can be seen that when the geometric figure after cutting is clear, the edge of the inner circle is blurred, or when the edge of the inner circle is clear, the geometric figure is blurred, and the geometric figure and the edge of the inner circle cannot be clear at the same time, which affects the lighting engineer's pursuit of the perfect artistic modeling of the stage light.
[0042] In view of the above problems, the utility model provides a cutter imaging device, which eliminates the original imaging circle, sets an imaging hole on the middle isolation plate, and installs a circular imaging hole device in the imaging hole. When cutting the light beam, the edge of the inner circle can be kept clear while the boundary of the geometric figure is clear, and the cutting boundary and the edge of the inner circle can be kept clear and synchronized within any angle range. Moreover, the imaging circle can be omitted, which saves the internal space of the stage lamp, meets the artistic modeling requirements of the lighting engineer for the stage lamp, reduces the manufacturing cost of the stage lamp, and especially improves the lighting effect.
[0043] Figure 3 This is the front view of the cutter of this embodiment. The cutter 20 mainly includes a base plate 21, a driving device and a cutter imaging device 22 installed on the base plate 21. Among them, the cutter imaging device 22 mainly includes four cutting components 221, and the four cutting components 221 are arranged symmetrically in a cross shape near the light path. Each cutting component 221 includes a cutting blade 2211 and two connecting rod mechanisms 2212 connected to the cutting blade 2211. The driving device drives the connecting rod mechanism 2212 to drive the cutting blade 2211 to move or rotate in the horizontal plane, so that the cutting blade 2211 partially blocks or opens the light path. By controlling the degree of blocking of the light path by each cutting component 221, different patterns are presented after the light passes through the cutter 20.
[0044] Figure 42 is a top view of the cutting assembly part in the cutter imaging device of this embodiment. The four cutting assemblies 221 of the cutter imaging device 22 are respectively located on the left side, the right side, the front side and the rear side. For the purpose of distinction, the cutting blade 2211 in the cutting assembly 221 located on the left side is called the first cutting blade 2213, the cutting blade 2211 in the cutting assembly 221 located on the right side is called the second cutting blade 2214, the cutting blade 2211 in the cutting assembly 221 located on the front side is called the third cutting blade 2215, and the cutting blade 2211 in the cutting assembly 221 located on the rear side is called the fourth cutting blade 2216.
[0045] Figure 5 A schematic cross-sectional view of a cutter imaging device provided by an embodiment of the utility model. The cutter imaging device 22 includes a fixed plate 222, which is specifically divided into an upper fixed plate 2221 and a lower fixed plate 2222. The upper fixed plate 2221 is located at the top of the cutter imaging device 22, and the lower fixed plate 2222 is located at the bottom of the cutter imaging device 22. A first light hole 2223 is provided at the center of the fixed plate 222 for the light beam emitted by the light source to pass through. The cutting assembly 221 is mounted on the lower fixed plate 2222 or the upper fixed plate 2221. The cutting blades (2213, 2214, 2215, 2216) and the isolation plates (223, 224, 225, 226, 227) of the cutting assembly 221 are located between the upper fixed plate 2221 and the lower fixed plate 2222. Each cutting blade is located between two isolation plates, that is, there is an isolation plate above and below each cutting blade. Among them, the top can be directly above or obliquely above, and the bottom can be directly below or obliquely below. An imaging hole 2251 is provided at the center of the third isolation sheet 225 located in the middle of all the isolation sheets, and second light holes 228 are provided at the centers of the remaining isolation sheets. All the second light holes 228, all the first light holes 2223 and the imaging hole 2251 are interconnected to form an optical path through which the light beam passes. The diameter of the imaging hole 2251 is smaller than the diameters of the second light holes 228 and the first light holes 2223.
[0046] Specifically, the spacers are stacked in the longitudinal direction, from bottom to top, they are: the first spacer 223, the second spacer 224, the third spacer 225, the fourth spacer 226 and the fifth spacer 227. There is a cutting sheet between every two spacers. The cutter imaging device 22 in this embodiment is from bottom to top: the lower fixed plate 2222, the first spacer 223, the first cutting sheet 2213, the second spacer 224, the second cutting sheet 2214, the third spacer 225, the third cutting sheet 2215, the fourth spacer 226, the fourth cutting sheet 2216, the fifth spacer 227, and the upper fixed plate 2221. The imaging hole 2251 of the third spacer 225 is installed with a circular imaging hole device 229 that cooperates with the imaging hole 2251. Among them, the circular imaging hole device 229 is an optical device, which is usually used in telescopes and cameras. It focuses light on a circular hole by focusing light to produce a clear imaging effect. Since the circular imaging hole device 229 is arranged on the third isolation plate 225 in the middle, the imaging of the cutting pieces on both sides of the imaging hole 2251 can be relatively clear, so that the boundary of the geometric pattern is clear during cutting while the edge of the inner circle can be kept clear. In addition, the cutting piece can achieve synchronous clarity in any direction and any angle range relative to the inner circle. However, the existing cutter imaging device has an imaging circle installed at the bottom. The imaging circle has a large gap with the cutting piece, which causes the geometric pattern in the cutting pattern and the edge of the inner circle to be unable to achieve synchronous clarity. In addition, the mechanical structure is complex, the cost is high, and the internal space is occupied. This affects the lighting engineer's pursuit of the perfect artistic modeling of the stage light.
[0047] However, when the circular imaging hole device 229 is set on the middle isolation plate, since the vertical spacing between the circular imaging hole device 229 and the cutting blade (2214, 2215) becomes as small as possible, if the circular imaging hole device 229 is deformed by heat under strong light, it will hinder the movement of the cutting blade (2214, 2215). Therefore, the circular imaging hole device 229 is a metal part made of molybdenum, which has a high melting point and excellent high-temperature performance. It is not easy to be deformed by heat in a high-temperature environment, and ELECOAT electrophoretic coating is applied on the surface of the circular imaging hole device 229. Therefore, the circular imaging hole device 229 has the properties of wear resistance, temperature resistance, and non-deformation. The effect of minimizing the spacing between the imaging hole 2251 and the cutting blade without affecting the movement of the cutting blade is achieved. The smaller the spacing between the imaging hole 2251 and the cutting blade, the clearer the imaging of the cutting blades on both sides of the imaging hole 2251.
[0048] Figure 6 The cutter imaging device provided in this embodiment cuts the pattern formed by the beam. Figure 6 It can be seen that when the geometric figure after cutting is clear, the edge of the inner circle is also clear, and the geometric figure and the edge of the inner circle can be clear at the same time.
[0049] Therefore, this embodiment uses a simple structure to make the cutter imaging device have clear geometric pattern boundaries and keep the inner circle edge clear when cutting, and keep the cutting boundary and the inner circle edge synchronously clear within any angle range. In addition, since the original imaging circle installed at the bottom is eliminated, a large part of the mechanical structure is omitted, the internal space of the stage lamp is saved, the lighting engineer's artistic modeling requirements for the stage lamp are met, the manufacturing cost of the stage lamp is reduced, and the lighting effect is especially improved.
[0050] The cutter imaging device of this embodiment can be applied to waterproof lamps and non-waterproof lamps.
[0051] In summary, the cutter imaging device of this embodiment allows the boundary of the geometric figure to be clear while maintaining the edge of the inner circle to be clear, that is, the geometric figure and the edge of the inner circle are synchronously clear, and can be synchronously clear in any direction and within any angle range relative to the inner circle.
[0052] The utility model also provides a stage light cutter, comprising: a base plate, on which a driving device and any one of the above-mentioned cutter imaging devices are installed, the driving device drives a connecting rod mechanism in the cutter imaging device, the connecting rod mechanism drives a cutting blade, and the cutting light beam forms a geometric pattern.
[0053] The embodiment of the utility model also provides a stage light, including a base, an XY-axis rocker bracket mounted on the base, a lamp body mounted on the XY-axis rocker bracket, and the above-mentioned stage light cutter, an optical lens focus and zoom system, and a light emitter mounted in the lamp body. The light projected by the light emitter passes through the stage light cutter, and the cutting blade is driven by a motor or other driving device to move and rotate to cut the light path, and then projected through the optical lens focus and zoom system, which can achieve more complex and varied geometric patterns or circular lighting effects.
[0054] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
