Abstract
A lighting fixture is provided which includes a rotatable lamp and reflector system which can be adjusted to direct its maximum candlepower at a desired vertical angle. The lighting fixture also includes a rotatable glareshield which can be adjusted to vary the height of the top of the shield to change the degree of shielding provided. The glareshield and the housing of the lighting fixture form an interchangeable unit which can be installed after wiring. The glareshield may be adapted to provide diffused or patterned backlighting. A removable supplementary baffle may be employed to prevent glare or reflected light from being viewed by a person beneath the lighting fixture, or to prevent undesired backlighting beneath the lighting fixture.
Claims12
In a lighting fixture which includes means for mounting the lighting fixture on a surface, and which includes a lamp and reflector system for projecting a beam of light through an aperture in the lamp and reflector system, said lighting fixture further including means connected to opposing first and second ends of the lamp and reflector system for pivotally supporting the lamp and reflector system such that the lamp and reflector system may be rotated about a first axis to vary the direction of projection of the beam of light which is projected through the aperture of the lamp and reflector system, means for adjustably shielding a portion of the beam of light which is projected through the aperture in the lamp and reflector system, the adjustable shielding means comprising:
- a curved shield, partially cylindrical in shape, having opposing first and second ends, an inner concave surface, and a second axis displaced from the first axis, at least a portion of the inner concave surface being exposed to the beam of light projected through the aperture in the lamp and reflector system;
- means, connected to the first and second ends of the curved shield, for pivotally supporting the curved shield such that the curved shield may be rotated about the second axis to vary the portion of the inner concave surface which is exposed to the beam of light projected through the aperture in the lamp and reflector system, whereby a desired portion of the beam of light projected by the lamp and reflector system is shielded by the exposed portion of the inner concave surface of the curved shield.
A lighting fixture, comprising
- a lamp and reflector system for projecting a beam of light through an aperture in the lamp and reflector system;
- means, attached to the lamp and reflector system, for removably mounting the lamp and reflector system on a mounting surface;
- an enclosure for the lamp and reflector system having an outer decorative surface which substantially surrounds the front and sides of the lamp and reflector system, and having an opening positioned substantially above the top of the lamp and reflector system to permit the beam of light to be projected outside of the enclosure, and further having a rear portion which partially surrounds the mounting means and which abuts the mounting surface, the rear portion including two or more slots extending forwardly from the mounting surface;
- and
- means for supporting the enclosure, wherein the supporting means is associated with the mounting means and is received by the two or more slots in the rear portion of the enclosure when the enclosure is positioned around the lamp and reflector system and the rear portion of the enclosure abuts the mounting surface, and whereby the enclosure may be installed after the lamp and reflector system has been mounted on the mounting surface and may be removed and replaced without dismounting the lamp and reflector system from the mounting surface.
In a lighting fixture which includes means for mounting the lighting fixture on a surface, and which includes a lamp and reflector system adapted to house at least one lamp bulb for projecting a beam of light through an aperture in the lamp and reflector system, said lighting fixture further including means connected to the lamp and reflector system for pivotally supporting the lamp and reflector system such that the lamp and reflector system may be rotated about a first axis to vary the direction of projection of the beam of light which is projected through the aperture of the lamp and reflector system, means for adjustably shielding a portion of the beam of light which is projected through the aperture in the lamp and reflector system, the adjustable shielding means comprising:
- a shield having an inner surface at least a portion of which is exposed to the beam of light projected through the aperture in the lamp and reflector system;
- means connected to the shield for pivotally supporting the shield such that the shield may be rotated about a second axis displaced from the first axis to vary the portion of the inner surface which is exposed to the beam of light projected through the aperture in the lamp and reflector system, whereby a desired portion of the beam of light projected by the lamp and reflector system is shielded by the exposed portion of the inner surface of the shield.
