Patent number: 8100559Abstract: A compact fluorescent lamp luminaire with chambered structure to improve ventilation for controlling the temperature of ballasts and lamp in the luminaire. In such compact fluorescent lamp luminaires a plurality of compact fluorescent lamps is arranged inside a dome structure. The compact fluorescent lamps are powered through ballasts. Heat generated by the lamps is exhausted out of the luminaires without air heated by the lamps from passing through a chamber housing ballasts of the luminaire.Type: GrantFiled: December 10, 2009Date of Patent: January 24, 2012Assignee: Sportlite, Inc.Inventors: Dan Meadows, Kory Schuknecht, William E.

Patent number: 5473522Abstract: A modular luminaire consists of a rectangular housing having a top, first and second sides and first and second ends, with an open light-emitting bottom. Elongated reflector members are located in a side-by-side relationship in the housing for independently reflecting the light from a compact fluorescent lamp from each of the reflector members out of the open bottom of the housing. The reflector members may be made as a single unit or as separate, independent individual units. The edges of the separate, individual reflector members are made to releaseably interconnect with one another; so that any desired number of reflector members and corresponding compact fluorescent lamps may be mounted in a side-by-side relationship in housings of different widths to provide the desired amount of light. Fixtures are designed to replace HID lamps and conventional, low efficiency fluorescent lamp luminaires.Type: GrantFiled: July 25, 1994Date of Patent: December 5, 1995Assignee: Sportlite, Inc.Inventors: Dale Kriz, Jerold Tickner

Patent number: 5377086Abstract: A lighting system employs luminaires having reflectors with a fluorescent lamp support frame at the base end of the inside of the reflector. The support frame includes a plurality of extensions for holding the bases of compact fluorescent lamps arranged in a general star configuration around the center line of the reflector. The extensions are at an angle to cause the compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector. A system of luminaires then provides a substantially uniform volume of light in a facility due to the patterns of overlapping light contributed by the individual luminaires.Type: GrantFiled: March 25, 1993Date of Patent: December 27, 1994Assignee: Sportlite, Inc.Inventor: Jerold A. Tickner

Patent number: 5197798Abstract: A conversion replacement apparatus for HID screw-in mercury vapor, metal halide or high or low pressure sodium lamps utilizes the reflector typically employed with such lamps. The HID lamp is removed from the reflector. A fluorescent lamp support frame then is attached to the base end of the inside of the reflector to extend to a point substantially one-fourth to one-half of the distance between the base end and the light-emitting end of the reflector. The support includes a plurality of extensions for holding the bases of compact fluorescent lamps arranged in a general star configuration around the center line of the reflector. The extensions are bent at an angle to cause the compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector. Ballasts for the lamps are located in a housing attached to the base end of the reflector.Type: GrantFiled: April 3, 1992Date of Patent: March 30, 1993Assignee: Sportlite, Inc.Inventor: Jerold A. Tickner
