It is among the objects of the present invention to provide an engineered light unit with a quick and accurate beam adjustment with minimum elort and which may be readily adjusted by either the fingertips o r by a pole to give a varying adjustment of a beam of light from afvertical position to a 45 position and through substantially 360 or a complete circle. Another object is to provide a novel recessed illuminating lxture which may be readily inserted in a ceiling or suspended from a ceiling and which has Wide application to show windows and interior displays and stores; to stage lighting and lobby displays in threatres; to altar lighting or pulpit lighting in churches; to specific lighting of selected paintings, sculptures or exhibitions in museums and to chalk boards or bulletin boards in schools.
A further object is to provide a combined short and long throw lighting unit, which may be equally used for spot or flood lighting, with either low or high ceilings, and which may also be utilized to provide the extra light required to overcome high absorptio-n of color iilters when used.
Still another object is to provide a novel recessed ilush lighting unit which may be readily and inconspicuously installed flush with nish plaster, and which will blend inconspicuously with Walls, partitions or with the ceiling, and which may be readily installed without difficulty in acoustical ceilings.
-Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by Way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.
Infaccomplishing the above objects it has been found most satisfactory according to one embodiment of the present invention to provide a reflector or spot light bulb with a swinging mount, which in turn is provided with a rotatable mount.
Desirably the entire structure is mounted inside of a cylindrical housing and a control knob permits change of angle or tilt of the reflector or spot light bulb carrier through an angle from zero to 45. This tilting of the light may be done by a ngertip control or by a pole, which will readily permit adjustment of the tilt of the spot light or reflector bulb.
The entire casing, including the tilting mount for the spot light or reflector bulb, may be readily rotated through substantially 360 by a slotted connection or other convenient means positioned on the flush cover of the casing receiving the tilting mount and the bulb.
Desirably an aperture plate, having a slotted opening, is provided at the bottom of the casing and flush with the ceiling, and this slotted plate is snapped into position or readily removed.
