Abstract
The utility model relates to a color wheel device for stage lamps. The color wheel device comprises a motor, a drive device, a support and a plurality of optical filters, wherein the optical filters are fixed on the support to constitute a color wheel, the motor drives the color wheel to rotate through the drive device, the optical filters deflects by a certain angle relative to a plane vertical to a principal optic axis. According to the utility model, besides that the color change of stage lamps can be realized favorably, the areas of photo-thermal effects inside lamp bodies can further be changed, so that the density of heat flows in the lamp bodies is reduced, and the heat radiation of the stage lamps is facilitated.
Description
Technical field
The present invention relates to the color wheel device of a kind of color wheel device, particularly a kind of stage lighting.
Background technology
Light of stage also is " stage illumination, lighting ", is one of stage design modelling means.Use light of stage equipment (such as lighting, magic lantern, control system etc.) and technological means, development along with the story of a play or opera, with photochromic and variation display environment, rendered atmosphere, outstanding central person, create stage spatial impression, time sense, mould the external of stage performance, and necessary lighting effects (such as wind, rain, cloud, water, lightning) etc. are provided.Wherein one of photochromic change approach is to rely on a kind of color wheel device.
Be traditional color wheel device as described in Figure 1, the plane 4 of optical filter is perpendicular to primary optical axis A, and the rotation of driven by motor colour wheel realizes the conversion between the different colours.Optical filter also must harmful ultraviolet ray and the hot infrared ray of generation height of filtering except saturating to useful visible light height.In the design process of stage lighting, well realize colour switching, the general design of colour wheel is from the closer position of light source.In the light path system of the distribution density high concentration of light, traditional color wheel device, the infrared light that reflects of mating plate concentrates in the very little zone centered by light source after filtration, a large amount of heat accumulations is in the light source place, be unfavorable for the heat radiation of light source, accelerate to a certain extent the speed of light decay, shorten light source life, serious meeting causes the bubble that goes out, and what impact was performed carries out smoothly.
Summary of the invention
The object of the invention is to improve the adverse effect that the traditional colour wheel apparatus produces light source heat radiation in the filtering infrared light.
To achieve these goals, a kind of stage lighting color wheel device of the present invention, comprise motor, transmission device, support, a plurality of optical filter, described optical filter is fixed in and consists of colour wheel on the support, motor drives the colour wheel rotation by transmission device, and described optical filter is with respect to the plane deflection certain angle perpendicular to primary optical axis.
Described optical filter is with respect to perpendicular to the plane deflection 0 of primary optical axis ~ ± 30 °.
Described optical filter, the optical filter of same color can be comprised of a main body or two halfbodies; The optical filter that wherein is comprised of two halfbodies becomes V-type to place; One side that is installed in support of two halfbodies that described V-type is placed, another is installed in the another side of support, and two halfbodies are overlapped.
Described optical filter is prism, and described prism is prism.
Described optical filter is coated with the corresponding film that designs according to deflection angle.
With respect to prior art, the present invention not only can be good at realizing the effect of colour switching, can also change the zone of lamp body interior lights fuel factor, reduces heat flow density in the lamp body, is conducive to the stage lighting heat radiation.
