(54) DEVICE FOR CREATING LIGHT EFFECTS

(57) The invention relates, in particular, to projection devices of theatrical technique, to kaleidoscopes, as well as to devices for creating lighting effects with musical accompaniment. The purpose of the invention is to increase the entertainment light effects. In the device, the triangular faces of 2 p-sided

element I are arranged vertically towards each other and are aligned laterally. When projecting the luminous flux from the light source 5 through the shaping stencils 8 and the light filters 9, light images are formed that enter the element 1. An image is formed on the screen 13, the peripheral part of which is created by the outer reflecting surface of the triangular faces 2 of the element I and the inner reflecting surface of the cylindrical body 3 When the body 3 is rotated with element 1 on the screen 13, varying combinations of the structure and texture of the pattern are formed. The execution of the inner surface of the body 3 of the transversely corrugated structure creates the illusion of the movement of light effects from the center to the periphery. 1 3.p. f-ly, 2 ill.

figure 1

The invention relates to devices for creating light effects, namely, projection devices of theatrical technique, to kaleidoscopes designed to produce colorful images that can be used to create ornamental stained glass windows, decorative mosaics, to select patterns and colors of fabrics, to light engineering, and can be used to illuminate the streets and interiors in the evening, in light-music, namely in devices for creating lighting effects with musical accompaniment.

The purpose of the invention is to increase the visibility of light effects.

Figure 1 shows the proposed device; Fig. 2 shows a projection kaleidoscope designed to create light effects on the screen using the proposed device.

The device comprises a n-sided element consisting of triangular faces 2 with reflective surfaces, which is housed in a cylindrical body 3 with a reflective inner surface with the help of fixing optically transparent plates 4.

Figure 2 shows a light source 5 on a single optical axis with a reflector 6, a capacitor 7, shaping stencils 8, a light filter 9, a kinematic system 10 dp of driving light filters 9 and shaping stencils 8 in motion of a n-sided element I with triangular faces 2, housed in a cylindrical housing 3, a kinematic system 11, driving a n-face element 1 with a cylindrical housing 3, a lens 12, a screen 13.

The proposed device works as follows.

When projecting the light flux, from the source 5 of the light focused by the capacitor 7 through the shaping stencils 8 and the light filters 9, the light images are formed, which enter the device for creating the light effects.

If the number of faces of the n-sided element p 4-8 in the center of the image, an image is formed on screen 13, the structure of which is created by the internal reflective surfaces of triangular faces 2 - the relative position of the n-gons, the internal texture of which depends on the pattern of the shaping stencils 8 and the color of the light filters 9. On the periphery of the central image, a less distinct image is observed, the structure and texture of which is mainly the central image. The external reflective surface of the triangular faces of the n-facet element and the internal reflective surface of the cylindrical body 3 participate in the creation of the peripheral image. The image on the screen 13 during the rotation (rotation around the axis) of the cylindrical body 3 with the n-sided element 1 will take part. this case in

in the center of the image, there is a counter-movement of the n-gons, the imposition of the structure of which and their internal texture at each subsequent time instant forms new unpredictable combinations in the structure and texture of the pattern. Along the periphery of the image, the figure is also in dynamics.

If the number of faces of the n-sided element 20 of the P7 8, the central image is mainly created by the shaping stencils 8 and is stained with the optical filters 9. There is no clearly pronounced structure created by the n-sided element 1 in the central image. The most spectacular in this case is the image created around the periphery of the central image. It consists of three to five most clearly distinguishable concentric circles, in each of which is observed by fan beams the reproduction of the image of the image, which diverges along radii. When rotating around the axis of a n-sided element 1 with a cylindrical body 3, there is a counter-movement of a number of fan-shaped elements located on the circumference

beams that, crossing and laying, create new pattern combinations both in structure and in texture. In addition, the movement of fan beams in each circle is independent of the neighboring circles. As a result, a colorful enchanting image is observed on screen 13, the individual elements of which are in independent motion.

The sharpness of the image decreases when concentric circles are removed from the center.

With the light reflecting surface of the n-sided element 1, it is obtained randomly structured. In this case, around the central image created by the shaping stencils 8 and colored by the light filters 9, a dynamic bright colorful luminous halo with an indistinct texture and structure is created. I

When the inner light reflectance of the surface of the cylindrical body 3 is made, the structure of the cross-corrugated peripheral image in all cases changes the luminosity of the waves, which is most spectacular in dynamics, as it creates the illusion of movement of light effects also from the center to the periphery.
