So generated color tristimulus values after being overlapped by two kinds there are the filter plate of spectrum intersection are as follows:
Wherein, τ1(λ) is the spectral transmittance of the first optically filtering piece, τ2(λ) is the light of second various optically filtering pieces
Compose transmittance.
Therefore the chromaticity coordinates of the color generated by two kinds of spectrum intersections are as follows:
It follows that using 2 kinds or two or more different spectrum but the optically filtering piece there are spectrum intersection, to be parallel to
The direction overlapping of optical axis or partial intersection together, that is, can produce the third mixing face in addition to the color of former optically filtering piece
Color.
Further, the filtering apparatus is made of the first optically filtering piece and the second optically filtering piece of different-waveband.
The filtering apparatus can also successively arrangement forms by the optically filtering piece head and the tail of three or four different-wavebands, the difference wave
Head and tail parts are overlapped the optically filtering piece of section in the direction of the optical axis.
The optically filtering piece can be the filter plate of solid color, and the optically filtering piece can be optically coated
Optical glass sheet.
Further, the optically filtering piece is divided into two or more regions of different colours.Preferably, described
Optically filtering piece is made of first area and second area, and wherein first area is optically coated optical glass sheet, the secondth area
Domain is not carry out optically coated optical glass sheet.
The present invention also provides a kind of stage lamp system with above-mentioned colour wheel, including light-source system and filter system, institutes
Stating filter system includes colour wheel and the driving device to drive colour wheel into and out optical axis, and the colour wheel includes colour wheel bracket
With the filtering apparatus being mounted on colour wheel bracket, the filtering apparatus is above-mentioned filtering apparatus.

Compared with the existing technology, the beneficial effects of the present invention are:
Since the optically filtering piece of different-waveband in the present invention is that the direction of optical axis is overlapped or partial intersection exists to be parallel to
Together, compared with traditional with the scheme of vertical optical axis direction splicing filter plate, there is no the splicing gaps between filter plate
Or splicing shelter, so will not influence the integrality for the light beam that the imaged system of stage lamp system comes out.In addition, due to two
There are laps for the optically filtering piece of different-waveband, can be with so other than the color that can obtain former optically filtering piece
The blend color between them is obtained, stage lighting is made to obtain various colors.
