Abstract

An area lighting fixture is constructed having a tubular pole member having a reflective interior surface and a light source mounted inside the pole and at a lower end thereof. A reflective, concave member is positioned below the light source and generally collimates light from the light source upward through the pole. An access opening covered by an access panel permits convenient access to the light source in the instance where the source fails. At the upper end of the pole, a light dispersing cap having a generally convex reflector receives the light from the source and disperses it around the pole.

Claims

1. A lighting fixture for illuminating an area comprising:

a tubular pole member having lower and upper ends and an interior reflective surface;

a light source in said pole member generally near said lower end;

an access panel covering an opening in said pole member proximate said light source for providing access thereto;

a concave reflector in said lower end below said light source and disposed for reflecting and focusing light from said light source to said upper end; and

a generally convex reflector mounted to an upper end of said pole member for reflecting light from said illumination bulb outwardly and downwardly.

2. A lighting fixture as set forth in claim 1 comprising a tinted plate positioned between said light source and said convex reflector for altering color of light from said light source.

3. A lighting fixture as set forth in claim 1 wherein a ballast for said light source is mounted inside said pole member.

4. A lighting fixture as set forth in claim 1 wherein said generally convex reflector is located in an upper region or a backlit sign and spaced apart from an upper end of said tubular pole member, with reflective surfaces positioned along inside edges of said backlit sign disposed for dispersing light from said generally convex reflector to rear portions of said backlit sign.

5. A lighting fixture for illuminating an area comprising:

a tubular pole member having upper and lower ends;

a light source mounted on an interior side of said pole member generally near said lower end thereof;

a reflector in said lower end and positioned below said light source and disposed for reflecting light from said light source to said upper end of said pole member; and

a light dispersing member mounted to said upper end of said pole member and constructed of a solid, light transmissive material having upper reflective surfaces therein for receiving and dispersing said light from said light source over said area.

6. A lighting fixture for illuminating an area comprising:

a tubular pole member having lower and upper ends;

a light source mounted on an interior side of said pole member generally near said lower end thereof;

a reflector in said lower end and positioned below said light source and disposed for reflecting light from said light source to said upper end of said pole member;

a light dispersing member mounted to said upper end of said pole member, for receiving and dispersing said light from said light source over said area;

a removable, transparent tinted plate mounted above said light source, for altering color of said light dispersed over said area; and

a lens mounted over said tinted plate, for focusing said light from said light source onto said light dispersing member.

7. A lighting fixture as set forth in claim 6 wherein said light dispersing member is disposed for illuminating a vertical surface and extends beyond at least one side of said vertical surface and is configured having interior surfaces for reflecting light from said pole member onto said vertical surface.

8. A lighting fixture for illuminating an area comprising:

a tubular pole member having lower and upper ends;

a plurality of illumination bulbs mounted on an interior side of said pole member generally near said lower end thereof;

a smaller, pilot light for each said illumination bulb of said light source and electrically coupled to each said respective illumination bulb, for indicating a failed condition of each said illumination bulb;

a reflector in said lower end and positioned below said illumination bulbs and disposed for reflecting light from said bulbs to said upper end of said pole member; and

a light dispersing member mounted to said upper end of said pole member, for receiving and dispersing said light from said bulbs over said area.
