ABSTRACT:
A gobo handling apparatus for use in a spotlight is disclosed. The spotlight has a housing supporting a light source producing a light beam and supporting at least one focusing lens. The spotlight includes an iris slot through the housing proximate the focal plane of the light beam. The apparatus of the invention comprises an elongated gobo housing removably inserted in the slot. The gobo housing has a central axis and an aperture therethrough for passage of the light beam in a direction normal to the gobo housing axis. The housing has a plurality of generally disk shaped gobo carriers each supporting a gobo, arranged side by side and movably contained within the housing. A drive mechanism contained within the housing operatively engages each of said plurality of gobo carriers for independently translating the gobo members along the housing axis into and out of the spotlight beam and rotating the gobo carrier in the spotlight beam in response to a remote control signal. The drive mechanism is driven by at least one motor attached to the housing for operating the mechanism in response to the remote control signal.
