Abstract
The utility model belongs to a laser rosy cloud-projecting device which adopts a holographic optical element to realize functions of color dispersion, convergence and collimation. The white light from a light source becomes the color light which is arrayed according to the spectrum after the light is diffracted through a raster, then the light is converged through a lens to become the quasi-parallel light to output, and at last a pattern like rosy cloud can be presented on a screen. The utility model is especially suitable for being used as stage velarium scanning lamps, various projecting lamps in dance halls and ornamental lamps in buildings, gardens, squares, etc.
Description
The utility model laser rosy clouds grenade instrumentation is that the laser hologram photography technology is applied to beautify life, is applicable to the Optical devices of the stage canopy of the heavens, dance hall shot-light.
The various shot-lights of existing dance hall, stage all are with incandescent lamp and a condenser, add and are furnished with look filter coating formation, and each window penetrates a kind of monochromatic hot spot.The filter coating of all kinds though can arrange in pairs or groups when adopting a plurality of window, each window still can only throw a kind of single color, obtains limited photochromic effect.Aspect the projection of the stage canopy of the heavens, developed a kind of laser stage setting device in recent years, do light source with copper steam (or Ar ion) laser instrument, each 1 of He-Ne laser, dispose micro-processor controlled optics, mechanical scanning system, cost an arm and a leg and multipotency is formed simple literal, pattern with red, yellow, green three coloured light scanning.Also need be equipped with professional and technical personnel's operation, safeguard.
The purpose of this utility model is a kind of laser rosy clouds grenade instrumentation that can obtain brand-new photochromic effect of design.It can throw gorgeous if the pattern of rosy clouds can scan again and draw irised simple text and pattern, and simple structure, cheap, in service need not the professional operation.
The utility model laser rosy clouds grenade instrumentation, adopt that the laser hologram photography method is made, be the holographic optical elements (HOE) of recording medium with the silver salt dry plate---holographic three intersection (or quadrature) gratings (also available mold pressing grating, ruled grating), hololens (also useable glass convex lens) are realized the chromatic dispersion and the alignment function of system.Its symphyogenetic result, the white light that incandescent light source is sent be decomposed into be arranged as by its spectrum composition red, yellow, green, blue ... be projeced into the space in monochromatic light, on this optional position, space receiving screen (for example wall), present gorgeous if the pattern of rosy clouds.
Be described further below in conjunction with 1 pair of the utility model device of accompanying drawing.
The divergent beams that incandescent light source 1 is sent, through holographic three intersection (or quadrature) gratings, 2 diffraction, be mutually 120 ° of (or 90 °) angle directions generation chromatic dispersions, be decomposed into red, orange, yellow, green ... after the monochromatic light array, import immediate holography (or glass) lens 3 again; Lens to the distance of light source 1 approximates its focal length, makes input light become quasi-parallel light after lens partly focus on and penetrates.It is an iris light beam.The arbitrary section that receives this light beam with screen can receive the rosy clouds pattern.The shape of pattern can be determined when making grating.For example be designed to quincunx chromatic dispersion, then its pattern is that a pistil (and is pressed red, yellow, green, blue from the edge to pistil for white, petal for colored ... color alignment) plum blossom.A kind of like this structure claims " single channel ".
According to different purposes, available several of the utility model device are combined into " multichannel " to dozens of.Accompanying drawing 2 is depicted as a kind of simple triple channel structure, can project three rosy clouds simultaneously.
Above-mentioned single-pass or multichannel device are installed in and carry out the 3-D scanning projection in the certain movement mechanism.Gated sweep speed both can " be sprayed " rosy clouds, and also can utilize persistence of vision effect " to draw " and go out rule rainbow, rich multicoloured decoration, brilliant.When scanning with single channel, also can " sweep " and go out letter symbol, stroke is sturdy, and is beautiful in colour, and effect surpasses the laser stage device, and make simple, cheap, operating maintenance convenient.
Accompanying drawing 2 is multi-channel structure example schematic of the utility model laser rosy clouds grenade instrumentation.
The utility model laser rosy clouds-projecting device is applicable to makes the various shot-lights in dance hall (platform), stage strip-light lamp, decorating building lamp, garden lamp, Square Lamp etc.
Claims (3)
1, a kind of laser rosy clouds grenade instrumentation is characterized in that by adopting the silver salt dry plate be that the holography of recording medium intersects identical hololens of (or quadrature) grating, one or more focal length or simple glass convex lens and incandescent light source and forms.
2, a kind of laser rosy clouds grenade instrumentation as claimed in claim 1 is characterized in that holographic (or quadrature) grating that intersects can be a glass chip, also can be embossed on the transparent membrane or delineation.
3, a kind of laser rosy clouds grenade instrumentation as claimed in claim 2 is characterized in that incandescent source places on the lens focus, can suitably add the colour filter (or film) of joining different colours near lens.
