Lighting fixture
First Claim
1. A lighting fixture for supporting an elongated light source which emits light radially from a longitudinal axis in an angular pattern which exceeds 180°
- , said fixture comprising;
an elongated reflector having a generally parabolic transverse cross-section with an axis of symmetry, said reflector having a pair of opposite edges which define an imaginary plane intersecting said axis of symmetry; and
lamp socket means for supporting said elongated light source in generally perpendicular relationship with said axis of symmetry, spaced from said reflector, and with said longitudinal axis disposed in said imaginary plane or on a side of said imaginary plane which is remote from said reflector.

Abstract
A lighting fixture emits a beam covering in excess of 180° by employing a reflector of parabolic cross-section and placing a linear light source perpendicular to the parabolic axis at or slightly forward of the parabola ends. A mounting plate containing the lamp socket and lamp ballast is connected to the reflector by means of a single screw to facilitate installation and maintenance. End members for the reflector include projecting collars which rotatably receive annular flanges from junction boxes through which power supply leads pass to connect to the lamp socket and pass through a raceway located behind the reflector to other fixtures mounted in tandem. The collar and flange can be secured together in any rotational position within a range of 360°. A swivel form of junction box includes two members which are mutually rotatable about an axis perpendicular to the collar/flange axis to increase the positional adjustability of the fixture.
