An improved apparatus for adjusting the azimuth and elevation of a light projector suitable for entertainment lighting, comprising a light source with associated light collecting and beam forming means (101) producing an elongated beam having an optical centerline. A means, typically a mirror (605), is used to redirect the beam at substantially right angles to the optical centerline (1), and is rotated (646) to vary beam azimuth through a first plane (2). Both the light source and the means for redirecting are coupled to a common mechanical support, which is rotated (636) around an effective pivot point (635) perpendicular to the optical centerline and parallel to first plane, to vary beam elevation through a second plane at substantially right angles to the first plane. The unique advantages of the apparatus for remotely-adjusted fixtures and for systems mounting a plurality of lighting fixtures to a common mechanical support are disclosed. |
