Description
Technical field
The present invention relates to light of stage technical fields, and in particular to a kind of optical system at kaleidoscope stage-lighting effect
System.
Background technique
Current stage performance requires theatrical art to can be realized innovation and reform, and light of stage is in theatrical art performance
Occupy important position, wherein light it is photochromic be light of stage design important link.The camera lens of the sealed beam lamp of existing stage
Generally use two kinds of structures camera lens: first is that traditional sealed beam lamp light path system using small ring away from Fresnel lens, this knot
The advantages of structure is that lamp body is slim and graceful, at low cost, the disadvantage is that low efficiency, beam effect are bad (edge is not sharp keen enough), stray light is serious
Deng；Second is that the most of sealed beam lamp now used is all made of simple glass imaging lens, the advantage of this structure is high-efficient, light
Shu Xiaoguo is good, the disadvantage is that it is at high cost, quality is too big so that lamp body is than cumbersome.Due to the dull coloring of existing light of stage,
Make designer's feeling beyond expression of words selling color work and getting up, therefore a kind of relatively new light of stage is needed to drill to set off stage by contrast
Atmosphere out renders plot, annotates stage personage heart emotional change.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of light coloring variation it is more, light expression way is rich
The rich optical system at kaleidoscope stage-lighting effect.
Based on this, the present invention provides a kind of optical systems at kaleidoscope stage-lighting effect, including bracket, are located at institute
State the concentric light source assembly set gradually, leaded light component, astigmatism component and concentrating component, institute on the same major axes orientation of bracket
Leaded light component is stated for the light source that light source assembly issues repeatedly to be imaged and be superimposed, the astigmatism component is used for will be through leaded light component
Superimposed light source dispersion refraction, light-resource fousing of the concentrating component for birefringence form multiple light sources picture, the astigmatism
Component be connected with drive astigmatism component rotate so that light source as dynamic change driving device.
The utility model has the advantages that the light source issued by light source assembly is superimposed by the multiple dioptric imaging of leaded light component, utilize later
Light source disperses after astigmatism component will be superimposed, and the light-resource fousing of refraction is formed multiple light sources picture by concentrating component, simultaneously because
Astigmatism component is connected with driving device, drives the rotation of astigmatism component, and stage-lighting effect finally formed in this way is in dynamic ten thousand
The in riotous profusion effect of cylindrical fireworks type, light coloring variation is more, light expression way is abundant, different lamp bead colors can be set also to reach
It is abundant color transformed, meet the light coloring demand of designer, atmosphere, rendering plot can be set off by reaching, and sufficiently annotate dance
The purpose of platform personage's heart emotional change.
Further, the distance between the astigmatism component and leaded light component are 1mm-5mm, the concentrating component and light

A certain distance also can be set in nearly leaded light component, enables the light of light source completely into in light conducting cylinder, leaded light component with
Astigmatism component distance is set as 1mm-5mm, and such astigmatism component can receive the light of leaded light component transmitting completely, while
The suitable distance of light source and concentrating component helps that light source is imaged when concentrating component is arranged, and finally passes out kaleidoscope
Stage-lighting effect.
Further, the light source assembly include lamp bead plate, the RGBW four-in-one LED lamp bead being mounted in lamp bead plate and
The illumination lamp bead being mounted on around RGBW four-in-one LED lamp bead.Since light of stage in the prior art does not have illumination generally
Function, illumination functions and lighting effects set off atmosphere function by contrast and cannot be considered in terms of, if therefore stage lighting illuminated and cannot be used using white light
The variation of monochromatic or colourama causes existing stage lighting system layout illumination functions to set off stage atmosphere by contrast, and of the invention
The RGBW four-in-one LED lamp bead of light source assembly setting and the effect that illumination lamp bead can meet illumination simultaneously and light of stage is taken into account
Fruit.
Further, the leaded light component is positive the light conducting cylinder of quadrangular frustum pyramid shaped.The light conducting cylinder of positive quadrangular frustum pyramid shaped can reach
Multiple refraction is carried out to the light source that light source assembly issues and the picture of multiple light sources is superimposed.
Further, two faces opposing upper and lower are disposed as square in the light conducting cylinder, and described positioned at lower part
The size of positive direction is greater than the size 1mm-2 mm of superposed positive direction.
Further, the astigmatism component is eight prisms or abrasive segments.It is separated to dissipate light source.
Further, eight prisms or the diameter of abrasive segments are bigger than the square side length of the light conducting cylinder bottom surface of positive quadrangular frustum pyramid shaped
5-20mm.
Further, the angle of taper of eight prisms is 5-20 degree, being capable of sufficient divergent light source.
Further, the concentrating component is plano-convex lens, and the focal length of plano-convex lens is 50-200mm, plano-convex lens
Diameter is 50-200mm.
Further, the driving device includes the motor being arranged on bracket, and the motor is driven by V belt translation to be dissipated
Optical assembly rotation, can be realized the dynamic change of light, reaches the lighting effects of kaleidoscope type.
