Abstract
An aimable luminaire has a lamp emitting light at the focus of a beam-forming lens held in a tubular housing having a lens on a central optical axis. The lamp is held in a lamp retainer which is transversely adjustable off the central axis of the housing and lens and axially adjustable with respect to the lens. When the lamp is moved off the optical axis, an off- axis beam is projected, and when the lamp is moved axially moved with respect to the lens the beam angle is zoomed larger or smaller. Rotation of housing in azimuth can then aim the light beam anywhere within a cone inscribed by rotation of the off-axis beam angle, thus providing adjustment in both elevation and azimuth. In a preferred embodiment either the transverse or axial position of the lamp may be the lamp may be adjusted from the proximal direction, above the ceiling, or from the distal direction by removing the lens from the distal end.
