INVENTION CONTENTS

[0004] The utility model provides a kind of stage lamp with superimposed filter to overcome at least one of the above-mentioned defects of prior art, utilize color superposition principle, realize when color piece disc cut into beam, final light spot can present multiple colors simultaneously.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is: a kind of stage lamp with superimposed filter, including lamp head and support frame, lamp head is pivoted on support frame, light source for generating beam is provided in lamp head, and color piece disc is provided along the direction of beam emission, the color piece disc is fixed with superimposed filter, the superimposed filter includes at least 2 pieces of superimposed dyeing piece, each dyeing piece includes transparent substrate and monochromatic coating layer on at least one side of each transparent substrate, each monochromatic coating layer has dyeing area and colorless area, when the superimposed filter cut into beam, the dyeing area of at least 2 monochromatic coating layers is simultaneously located in beam.

[0006] The superimposed filter includes at least two superimposed dyed pieces, each of the dyed pieces including a transparent substrate and a single-color coating layer on at least one side of each of the transparent substrates, each of the single-color coating layers having a dyed area and a non-dyed area, and the superimposed use of the dyed pieces causes the color superposition of the dyed area and the dyed area or the color superposition of the dyed area and the non-dyed area of different dyed pieces, thereby matching a variety of color categories, making the color more brilliant during stage performance, and because the single-color coating layer has a single color, the plating process is simple, the manufacturing cost is low, the dyed areas of different dyed pieces will not affect each other during plating, thereby making the color separation clear and sharp, and there is no interval black line; at the same time, the design of the area distribution of the dyed area and the non-dyed area in the dyed piece increases the overall color distribution combination on the superimposed filter, thereby creating more color effects.

[0007] Further, the color of each of the single-color coating layers is one of cyan, magenta, and yellow, or the color of each of the single-color coating layers is one of red, green, and blue. The three primary colors of cyan, magenta, and yellow are based on subtractive color mixing, and the three primary colors of red, green, and blue are based on additive color mixing, and the color contrast between each group of three primary colors is sharp, giving a strong visual impact to the audience.

[0008] Further, the dyed area includes a dark color unit, a light color unit, or a gradient color. The dark color unit or the light color unit or a mixture of the dark color unit and the light color unit can be selected according to actual use requirements, thereby increasing the selectability of color matching.

Thus, the color partition of the whole superimposed filter has a unified center, and the color distribution is clear and refreshing, and will not be too messy.

[0011] Further, when the superimposed filter is cut into the light beam, the light beam center passes through the co-vertex fan-shaped blocks formed by the dyed areas of the single-color coating layers. Thus, the final light spot presents a center outward radiation of different color regions.

[0012] Further, in the light beam emission direction, at most two dyed areas are superimposed at the same time. The color after the superposition of the dyed areas is accurately controllable, and the superposition of too many layers leads to unpredictable color, thereby simplifying the color design and adjustment and replacement.

[0013] Further, a part of the dyeing area on the single-color coating layer is overlapped with the dyeing area on other single-color coating layers, and the remaining part of the dyeing area is overlapped with the colorless area on all the remaining single-color coating layers. More diverse color matching modes can be achieved, and the color design arrangement is enriched.

[0014] Further, the transparent substrate is provided with single-color coating layers on both sides along the light beam emission direction. The number of transparent substrates is reduced, thereby reducing the thickness of the superimposed color filter, and the color separation can be clearly imaged.

[0015] Further, the superimposed color filter comprises three superimposed transparent substrates, and the single-color coating layer is located on one side of each transparent substrate. The three transparent substrates carry three single-color coating layers, which can simultaneously satisfy the combination of three colors, present more rich color combinations, and the thickness of the superimposed color filter is also within an acceptable range. The process of the single-color coating layer on one side of each transparent substrate is also simpler.

[0016] Further, a plurality of superimposed color filters are arranged on the color sheet disc. Different color categories and different color arrangements of superimposed color filters can be arranged on one color sheet disc at the same time, providing more effect options for stage performance.

[0017] Further, the edges of adjacent dyeing sheets are fixed by glue. The glue bonding prevents the dyeing sheets from moving out of position, and the edge fixing method can make the superimposed dyeing sheets not be affected by the glue, which is more beautiful and saves installation time and cost.

[0018] Further, the edges of adjacent dyeing sheets are fixed by glue. The glue bonding prevents the dyeing sheets from moving out of position, and the edge fixing method can make the superimposed dyeing sheets not be affected by the glue, which is more beautiful and saves installation time and cost.

[0019] Further, the superimposed color filter is provided with a sealing glue on the outer periphery to seal the gap between adjacent dyeing sheets. Dust or other foreign matter is prevented from entering the superimposed color filter, which affects the light effect by blocking the light beam.

[0020] Further, the color sheet disc has a light transmission hole corresponding to the superimposed color filter, and a positioning groove is arranged on the inner edge of the light transmission hole, and the superimposed color filter is fixed in the positioning groove. The positioning and installation of the superimposed color filter during installation are facilitated.

[0021] Further, the lamp head is provided with a beam splitter capable of cutting in and out of the light beam on the light-emitting side of the color disc, and the beam splitter is rotatably fixed on the mounting plate through a pivot seat. The beam splitter can expand a single light beam into multiple light beams, realizing splitting or diffusion of the light beam. Through the cooperation of the beam splitter and the superposition filter, colorful and dynamic optical effects can be brought to the stage performance, realizing colorful changes and dynamic effects of the light beam.

[0022] Further, the number of the beam splitters is 2 or more, each of the beam splitters corresponds to a pivot seat, and at least two of the beam splitters can be superimposed and located in the light beam at the same time. The combination of two or more layers of beam splitters can further enhance the light dispersion effect, and the superposition of the refraction effect of the beam splitters can produce more significant spectral separation and exhibit more bright and rich colors.
