Abstract
Abstract This assembly includes a lamp housing mounted to a support at one end and having a pair of apertures at the other end providing reading and examination lights. A lamp base is journal mounted within the housing to the housing sidewalls by pivot elements which are fixed to the lamp base and extend outwardly of the sidewalls. Actuating levers are attached to each end of the pivot elements for manual rotation of the lamp base to direct the lamp beam through one or the other of the apertures. The housing is attached to the support by an elbow joint, which permits the angle of elevation of the housing to be adjusted and the support includes a swivel joint which permits the housing to be rotated about its own longitudinal axis.
