Abstract: A replacement fluorescent lighting adaptor for adapting a fluorescent lamp to an incandescent lamp connector includes a base defined by an annular inner wall and an annular outer wall surrounding the inner wall and spaced from the inner wall defining a cavity. The inner wall includes a contact assembly for making electrical contact with the fluorescent lamp contacts and a portion to receive the fluorescent lamp base. A reflector including a narrow neck portion and a longitudinally, outwardly expanding portion is fitted to the base receiving portion by the narrow neck portion. The cavity includes a first cavity portion between the lamp base-receiving portion and the outer wall in which an annular electrical ballast member is positioned. The outer wall is spaced from the reflector in order to improve heat dissipation of the electrical ballast. An annular capacitive device is positioned in a second cavity portion between the contact assembly and the outer wall.

Abstract: A replacement fluorescent lighting device includes a fluorescent lamp having a plurality of parallel tubes elongated along an axis and a reflector with an annual reflecting inner surface surrounding the tubes. The inner surface includes at least one surface, or surface segment, that is defined by a geometric curve rotated at least partially about a given axis, with the curve having a focal point that is laterally offset from the given axis in order to have a focal ring segment to enhance light emitted by the surface of the fluorescent tubes. Multiple surface segments are defined about an axis offset from the lamp axis of elongation and spaced radially around the fluorescent lamp. These segments are positioned at major lumen output lobes of the lamp.
