An illumination lamp apparatus.

摘要

An illumination lamp apparatus comprising a frame formed of plastics material support boards (10-12)mounted in parallel relation perpendicular to the main axis of the apparatus and means (14,16) spacing said support boards from one another. Mounted on the frame is an illumination source (24), and means for projecting a beam of light therefrom along the main axis of said apparatus. A gobo disk (44) rotatable about an axis parallel to said main axis and includes a plurality of shaped apertures (52-57) distributed circumferentially of said gobo disk and selectively positionable in said beam; an iris (40) is mounted fowardly of said iris. Means are provided to move the lens assembly (36) so that its focal point is either accurately in the plane of gobo disk (44) or in the plane of the iris(40).
