Abstract:
An aimable-beam luminaire (40) including:a generally cylindrical tubular housing (41) having a proximal end (43), a distal end (44) and an optical axis (60) therethrough;a lens (50) on the optical axis at the distal end of the housing and having a focus (45) within the housing;a lamp (42) within the housing approximately at the lens focal plane;a lampholder (64) for holding the lamp near the proximal end of said housing, said lampholder having means for transverse adjustment off the nadir axis whereby the lens may be positioned to project light from said lamp into a light beam at an off-axis elevation angle (A) with respect to the nadir axis of the lens and housing;means (53,54) for supporting and rotating the housing in a planar ceiling (55) whereby the off-axis beam projected by the lens may also be aimed in azimuth;means (51) for removing the lens from the distal end of the housing with the luminaire mounted in said ceiling, whereby the lamp may be replaced and the axial and transverse positions of the lamp may be positioned by reaching through the distal end of the housing from below said ceiling.
