Description

c- The invention relates to light music, namely, devices for creating light effects in light-music installations, and can be used in dynamic light-effect devices, in advertising.

The closest in technical essence to the present invention is an output device of a light-music installation comprising a light source with a reflector placed in a housing, a shadow projection screen with light filters and shaping elements. In parallel with it, and between it and the light source, a translucent carrier disk is placed, containing holes, lenses and lighting elements. Parallel to the carrier disk and the shadow projection stencil, there is a screen on which light effects are projected. In these light effects, mainly, light images dominate, the outlines of which are clearly marked and have a geometric pattern embedded in the forming elements.

Such lighting effects cannot accompany musical works.

for example, of a soft lyrical character — the light-music composition being created will lack the effect of a luminous sound. which is annoying to the viewer.

The purpose of the invention is to expand the artistic and visual capabilities of the device.

The goal is achieved by the fact that in the output optical device of a light-music installation containing light sources with reflectors installed in the housing, arranged parallel to one another and can be rotated relative to the longitudinal axis, the carrier disk, above the holes of which reflectors are located, are stencils of a shadow projection with multicolored light filters and shaping elements, and an image acquisition screen, the body is made in the form of a multifaceted truncated pyramid, the screen is located on a large the pyramid bearing disk is installed between the screen and the shadow projection stencil, a part of the inner surface of the body located in the reflecting area of the reflectors of the disk has a reflective texture

the coating has a light absorbing coating.

Figure 1 shows the output optical device with a veto-musical installation, section; figure 2 is a variant of the carrier disk, top view.

The output optical device of the light-music installation contains four sources 2 of light placed in housing 1 with reflectors 3, in front of which two stencils 4 of shadow projection are installed sequentially and parallel to each other, each containing light filters 5 and shape-generating elements 6. Also parallel to the latter from sources 2 lights 4 of the shadow projection is placed a carrier disk 7 of opaque material containing holes 8, in front of which the reflectors 9 are fixed at an angle of 40-70 ° to the plane of the carrier disk ka 7 ..

The inner surface of the housing 1, located in the reflection zone of the reflectors 9, has a reflective randomly textured coating 10, and the rest of the surface has a light-absorbing coating 11. In the expanded part of the housing 1 there is a screen 12. Stencils 4 of the shadow projection and the carrier disk 7 are rigidly connected kinematic node 13. The carrier disk 7 (figure 2) contains holes 8 and reflectors 9 fixed above them.

The device works as follows.

When the light fluxes from the light sources 2 pass through the light filters 5 and the shaping elements 6 of the stencils 4 of the shadow projection rotating with the help of the kinematic node 13 ,. the light fluxes undergo a transformation and a change in color.

When projecting such light fluxes through the holes 8 of the carrier disk 7, in front of which there are no reflectors 9, colorful but geometrical images appear on screen 12: the configuration and movement of the images are due to the configuration and movement of the shaping elements b.

The transformed colored light fluxes passing through the openings 8 with reflectors 9 fall onto the reflector 9 and are reflected by it towards the inner surface of the housing 1 having a reflective, randomly textured coating 10, which, in turn, reflects this light flux to the screen 12 As a result of these reflections, the light times undergo changes: the texture and contours are crushed, radiated, illusive, flowing, because

the rays of colored light from a series of images are combined, alternating, superimposed on each other in short periods of time. Thus, a tender and out of the color structure of the light-color image is formed, which cannot be created by any other structures.

To eliminate stray light

0 on the screen 12 from the external light, or the reflected internal between the reflective randomly textured coating 10 and the screen 12 is placed a zone with a light-absorbing coating 11.

5 Stencils 4 shadow projections have shaping elements 6, made in the form of slit decorative and ornamental patterns or in the form of bulk light-scattering elements. During the rotation of these stencils 4 as a result of the mutual superposition of the shaping elements 6, the structure and color of the light beam from the light source constantly change.

5 Bearing disk 2 also has holes - large and small. Moreover, through small holes 8, the light is projected directly onto the screen 12, and opposite the large ones are installed reflective

0 elements 9, which reflect the light beams toward the light reflecting textured coating 10, which is set in such a way that the light from it is projected already towards the screen 12.

5 The textured surface of the mirror film additionally transforms the incident light beam in such a way that non-geometric light patterns are already projected onto the screen as from

0 stencils, and shaky, slippery glare, similar to the glare of light from the water. This effect is achieved due to the uneven surface of the reflective coating 10, as a result of which the light rays are reflected from

5 different zones of this coating 10 into different zones of the screen 12. Due to the slow rotation (not more than 0.2 rpm) of the carrier disk 7 with reflectors 9, the light beams will drop all

time for new zones of the retroreflective coating 10 and give new effects.

Light reflectors 9, rectangular-shaped mirror plates, are mounted at an angle of 40 ° -70 °.

To obtain a reflective coating of the coated coating, the mirror captive is glued onto the inner surface of the housing, pre-coated with glue, for example, H-88. The irregularity of the surface of the mirror film will be random in this case.
