Abstract
The utility model belongs to a lighting device in a stage (hall) and entertainment places, particularly a scenery device which uses laser and curved face raster for generating various colors. A laser generates light beams with various colors are projected on the curved face raster after concourse refracting by a reflector. The light beams with various can produce a plurality of interference stripes after beam splitting on the curved face raster. Because the light generated by the laser are basically distributed whole range of a spectral region, the interference fringes form varicolored technicolored dreaming graphs in space.
Description
The utility model belongs to the illumination in stage (Room) and recreation place etc., is a kind of laser setting device.
Existing in existing laser setting at present: vector scan Lissajou's figure, conoscope image and diffraction pattern.The foundation of laser scanning figure is based on the effect that persists of human eye vision, can produce the Lissajou's figure of wide region in this way, perhaps roulette.Conoscope image is by the irregular surface deflecting light beams that moves or by these surface reflection bundles, can produce conoscope image, can the various laser clouds of projection according to the structure difference on surface.Diffraction pattern utilizes the diffraction and the reflection of hologram diffraction plane grating, and perhaps the chromatic dispersion by spectrum forms the polychrome hot spot, can produce another kind of keynote background effect.Above narrate all with the figure dullness, and most figure all is that regular figure or wire and point-like figure occur.Therefore it tell on more inflexible.In these setting devices, the used optical element of laser beam splitter all is a plane grating.
The utility model provides a kind of curved surface grating of using laser beam splitter, and it is stronger to produce color, the laser setting device with three-dimensional dreamlike effect.
The effect that it is produced with regard to curved surface grating and plane grating is to finish two kinds of different styles.Doing the setting device with grating mainly is to use the striped of grating laser beam splitter, and plane grating can only be dispersed into many light beams (this depends primarily on the fringe number of grating) that penetrate with rectilinear direction to beam of laser.Curved surface grating is then different, because on the surface of curved surface grating except the effect that can produce plane grating, and many light beams that beam splitting goes out form focus again aloft, produce interference fringe, driven by motor curved surface grating rotation in addition, diffraction pattern and interference fringe are coincided, produce the unthinkable dreamlike effect of many people's thinkings.
Structure of the present utility model is as shown in Figure 1: by the He-Ne laser instrument, and argon ion laser (Ar+), speculum 1,2,3,4, curved surface grating 6, motor 5 is formed.
Fig. 2 is a structural representation of the present utility model.
Argon ion laser sends the mixed light of indigo plant, green wave band, and the He-Ne laser instrument sends ruddiness.The mixed light of the bluish-green wave band that argon ion laser sends reflexes to speculum 2 by speculum 4, projects on the curved surface grating 6 through speculum 2.The ruddiness that the He-Ne laser instrument sends by speculum 1,3,4, reflexes to speculum 2, projects on the curved surface grating 6 through speculum 2.The bluish-green mixed light of argon ion laser and the ruddiness of He-Ne laser instrument converge on speculum 4, project to simultaneously on the curved surface grating 6 through speculum 2.Curved surface grating 6 is divided into purple, indigo plant, Huang, six singlets such as green with the full spectral line of Ar+ laser, adds that the IR spectra of PVDC of He-Ne laser instrument casts out.Because curved surface grating 6 differs from plane grating, what projected is not several very clearly demarcated spectral lines, but these several the wavestrips that various spectral lines mix that spectral line intersects to form mutually.Drive grating rotating by motor 5.Motor 5 is by monolithic processor controlled walking motor, programme controlled walking motor 5 is set at fast, at a slow speed, speed change, rotating or the like, resemble during the scene that so aloft forms rack, the time and resemble flowing water.
The used curved surface grating 6 of the utility model comprises concave grating, convex grating and S face light coral.
The argon ion laser chromatogram is in the indigo plant-green light spectrum district based on 514.5nm and 488.0nm, and He-Ne laser instrument chromatographic zone is the 632.8nm redness.Argon ion laser makes light beam be distributed in the whole wave band of spectral regions substantially with combining of He-Ne laser instrument like this.With curved surface grating 6 separate color, just formed colourful, bright various dreamlike figure in the air whole like this.As: water wave fluctuation, cloud roll ...Build a kind of very romantic, as if one were in fairyland sensation, be particularly suitable for the light atmosphere of singing the nightclub that dances exquisitely, also be applicable to stage, dance hall and various public place of entertainment.
Embodiment of the present utility model is as follows:
The material of speculum 1,2,3,4 is K
9, deielectric-coating is a multilayer, reflection wavelength 4579 ～5145 .Several 100 lines per millimeters of curved surface grating 6 lines, two dimension, wavelength 3350 ～6438 , concave surface.The argon ion laser model is 822 types, and wavelength 4579 ～5145 , power are 8 W (full spectral lines), and pattern is TEMOO, the angle of divergence≤1mr.The wavelength of He-Ne laser instrument is 6328 , power 10mw.Motor 5 models are the 45BF003 type, and control mode is a three-phase six-beat, and stepping angle is 1.5DEG/STEP.
