Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to an optical system with brilliant light spots and a stage lamp having the same. Background Art

[0002] A multifunctional stage light combines a variety of light spot effects, thanks to various types of effect modules compactly installed inside the lamp head. For example, by cutting the pattern piece in the pattern module into the light beam, the lamp head projects a specific pattern onto the target plane. At this time, a prism module is added, and the single pattern in the target plane is split into multiple pattern arrays arranged in a certain pattern. If the color filter in the color film module is cut in, the color of the entire pattern is changed, and so on. Combining different modules in various ways can make the light spot have a variety of changes. However, the stage lights on the market today have a relatively single light spot color effect, and their dynamic effect is just to add dynamic rotation to the pattern light spot. There is an urgent need for a stage light with more complex color changes to create more colorful light spots to meet the pursuit of richer stage lighting effects by stage designers. Utility Model Content

[0003] The utility model is to overcome at least one defect of the prior art, and provides an optical system with brilliant light spots and a stage light having the same, and solves the problem that the color of the stage light spot is too single by setting a colorful film.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an optical system with brilliant light spots and a stage light having the same, wherein the optical system with brilliant light spots includes a light source for generating a light beam, a first effect module and a second effect module for intercepting the light beam, the focal distance between the first effect module and the light source is less than seventy percent of the focal length of the light source; at least one dazzling color film is arranged on the first effect module, the dazzling color film has a plurality of color zones, and the colors of adjacent color zones are different from each other, and under the drive of the revolution drive module, the dazzling color film has a first position for intercepting the light beam to generate a first light effect, and a second position outside the light beam, and when the dazzling color film is located at the first position, at least two of the color zones intercept the light beam at the same time, and the second effect module interferes with the light beam at the same time to generate a second light effect superimposed on the first light effect.

[0005] Placing the colorful film near the focus of the light source is conducive to the imaging of the color area, and the light spot projected to the target plane has multiple color domains with clear boundaries. The colors of the adjacent color areas are different and at least two of the color areas intercept the light beam at the same time, so that the light spot has at least two colors, which effectively solves the problem of the stage light spot having too single color; and when the colorful film is in the first position, the second effect module interferes at the same time. At this time, the first light effect and the second light effect are superimposed, so that the color and pattern of the light spot are simultaneously complexly changed, presenting a colorful light spot effect.

[0006] Furthermore, the focal distance between the first effect module and the light source is less than 50% of the focal length of the light source, so as to provide the first effect module with sufficient operating space and make it as close to the focal point of the light source as possible, so as to achieve clearer imaging.

[0007] Furthermore, the first effect module also includes a substrate, and a plurality of first effect sheets are arranged around the periphery of the substrate in the circumferential direction around the revolution center thereof, and the revolution drive module drives the switching of the dazzling color sheet and the first effect sheet to intercept the light beam respectively. The dazzling color sheet and the first effect sheet are installed in the form of an effect disk, so that the first effect module can install as many different types of effect sheets as possible, and the optical system has more light effects.

[0008] Furthermore, the first effect sheet is a color filter, which filters the light beam passing through it, allows light of a specific wavelength to pass through, and then renders the light beam in color, projecting a light spot of a corresponding color onto the target plane.

[0009] Furthermore, the colorful film includes at least two layers of overlapping color films, the color films are provided with color units, and the color area is formed by overlapping the color units on the color films. By arranging color units of different colors on different color films, overlapping each other, and combining with a special arrangement, the color units can be overlapped in the direction of light emission to form a color area in a relatively simple way.

[0010] Furthermore, the color of the color unit is a single primary color. The color units with different single primary colors can be combined with each other to form color areas of multiple colors, and the designer can choose different combinations according to design requirements.

[0011] Furthermore, the shapes and / or colors of the color areas on the colorful film are randomly distributed, which produces more random combinations, and the shapes and colors of the color areas are more diverse, making the light spot effect more dynamic.

[0012] Furthermore, it also includes a rotation driving module for driving the colorful film to rotate. The colorful film rotates so that the light spot color area formed by it also rotates, making the effect more vivid.

[0013] Furthermore, the first effect module is also provided with a light hole allowing the light beam to pass freely. When the designer does not need the first effect module to produce light effects, the light hole can be cut into the light beam. With this arrangement, the first substrate does not need to be cut out of the light beam as a whole, thus saving the space occupied by the first effect module.

[0014] Furthermore, the second effect module is located at a side of the first effect module away from the light source. When the dazzling color sheet is located at the first position, the light beam passes through the dazzling color sheet and then enters the second effect module.

[0015] Furthermore, the second effect module is one of a prism module, a rotating pattern plate module, a fixed pattern plate module, a color plate module or an atomization module. When the second effect module is a prism module, the light beam passes through the colorful film to generate a light spot with multiple color areas, and then after differentiation by the prism module, multiple colorful small light spots arranged in a certain pattern are presented on the target plane; when the second effect module is a rotating pattern plate module, the optical system projects a pattern with a colorful effect to the target plane; relative to the fixed pattern plate, when the second effect module is a fixed pattern plate module, the colorful effect pattern formed has a dynamic effect of rotation, and the light effect is more vivid; when the second effect module is a color plate module, the two light spot colors are combined and superimposed; when the second effect module is an atomization module, the color area boundary formed by the color area is blurred, and the light spot is formed by a combination of multiple color blocks. By combining various effect modules with the colorful film in the first effect module, the optical system has more light effects.

[0016] The utility model also provides a stage light, having any of the above-mentioned optical systems, and also comprising a lamp head with a light outlet, wherein the optical system is located inside the lamp head, and the light source is located at an end of the lamp head away from the light outlet, so that the stage light has a richer, more flexible and more colorful light effect.
