1. Color-changing apparatus for a light assembly having a light source that generates a light beam in at least an axial direction, said color-changing apparatus comprising:
- a first lens and a second lens spaced apart therefrom, the first lens and the second lens positioned in a path defined by an axial direction of the light beam;
at least a first filter flag formed of a first color, said first filter flag exhibiting along at least a portion of a length thereof a first range of first color-saturation gradations in the first color;
at least a first filter-flag positioner for supportively positioning said at least first filter flag at least selectably at an angle offset from the axial direction of the light beam, said first filter-flag positioner for translating said first filter flag selectably to position a selected portion thereof in the light beam, a light-beam characteristic of the light beam dependent upon which portion of said first filter-flag forms the selected portion selectably positioned in the light beam; and
wherein said first filter flag is positionable by said first filter-flag positioner between the first lens and the second lens.

Abstract
Color-changing apparatus, and an associated method, for a lighting assembly. One or more dichroic filters are selectably positioned in the path of a light beam generated by a light source. A positioner supportively positions the dichroic filter and effectuates its translation into and out of the path of the light beam. A set of dichroic filters, each separately supported by a separate actuating positioner permits a combination of dichroic filters to be combined to cause the light color of the light beam to be of any desired color.

13. Color-changing apparatus for a light assembly having a light source that generates a light beam in at least an axial direction, said color-changing apparatus comprising:
-
at least a first filter flag formed of a first color, said first filter flag exhibiting along at least a portion of a length thereof, a first range of first color-saturation gradations in the first color, the first range of the first color-saturation gradations extending along the first filter flag to define a less saturated region of the first portion and a more saturated region; and said first filter flag further comprising a second portion, the second portion exhibiting a first selected constant saturation level; and at least a first filter-flag positioner for supportively positioning said at least first filter flag at least selectably at an angle offset from the axial direction of the light beam, said first filter-flag positioner for translating said first filter flag selectably to position a selected portion thereof in the light beam, a light-beam characteristic of the light beam dependent upon which portion of said first filter-flag forms the selected portion selectably positioned in the light beam. - View Dependent Claims (14)

15. A method for selectably changing a color of a light beam generated at a light source of a light assembly, the light beam generated in at least an axial direction, said method comprising:
-
positioning an optical assembly comprising at least two lens in a path defined by the axial direction of the light beam; supportively positioning a single first filter flag at least selectably at an angle offset from the axial direction of the light beam between the two lens and moveable across the light beam, the single first filter flag formed of a single first color, and the first filter flag exhibiting along at least a portion of a length thereof, a first range of first color-saturation gradations in the first color; and supportively positioning a single second filter flag in the light beam between the two lenses and moveable across the light beam, a light-beam characteristic of the light beam dependent upon positioning of the single first filter flag and the single second filter flag is positioned in the light beam to integrate the light and to provide a single color output beam. - View Dependent Claims (16, 17, 18)

19. Apparatus for selectably altering characteristics of a light beam generated by a light source of a light assembly, said apparatus comprising:
-
a first filter flag having a first part and at least a second part, the first part of the said first filter flag exhibiting first color characteristics and the second part of said first filter flag exhibiting second color characteristics, any of the first part and the at least the second part of said first filter flag positionable in the light beam; a second filter flag having a first part and at least a second part, the first part of said second filter flag exhibiting third color characteristics and the second filter flag exhibiting fourth color characteristics, any of the first part and the at least the second part of said second filter flag also positionable in the light beam, selection of which parts of said first and second filter flags, respectively, positioned in the light beam determinative of lighting characteristics thereof;
said first and second filter flags selectably positionable through sliding, linear translation along an axis substantially perpendicular to the light beam.

20. Color-changing apparatus for a light assembly having a light source that generates a light beam in at least an axial direction, said color-changing apparatus comprising:
-
a first lens positioned in-line with the light beam, said first lens for redirecting light energy of the light beam incident thereon in directions generally parallel to the axial direction of the light beam; a filter flag formed of at least a first color supportively positioned, through linear translation, at an angle direction offset from the axial direction of the light beam and in-line with the light beam, once redirected by said first lens, said filter flag for coloring the light beam; a second lens positioned in-line with the light beam, once colored by said filter flag, said second lens for shaping the light beam in a desired manner; and a linear translation actuator for actuating translation of said filter flag to position a selected portion of said filter flag in the light beam.
