Abstract
An aimable fiber-optic spotlight has a fiber-optic light guide with a first end receiving light from a remote light source and a second end emitting light at the focus of a beam-forming lens held in a fixed tubular housing having a lens on a central optical axis. The light-emitting end of the light guide is held in a tubular light guide retainer within the housing, and which is transversely adjustable off the central axis of the housing and lens. Light emitted from the light guide is off the central axis of the housing and lens, and is thus projected through the lens as an off-axis beam adjustable in elevation angle. 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 the light-emitting end of the light guide is axially adjustable with respect to the lens, whereby the angular diameter of the projected light beam is also adjustable.
