Abstract
Fluorescent lamp assemblies with screw-in bases and solid-state ballasts, useful indoors or outdoors, such as in reflector spotlight or floodlight or table lighting. A two-piece non-conductive housing is retained simply by a pair of screws or the like, and laterally surrounds a fluorescent lamp assembly and its ballast, and also has a ratcheting screw-in Edison base on one end and a lens covering the light-emitting opposite end. Families of such lamp assemblies with different wattages and/or different beam-spreads are suitable for such usage, and for use in canister-like ceiling or wall fixtures.
Claims24
Fluorescent lamp assembly with axial symmetry, comprising a fluorescent lamp bulb and a solid-state ballast therefor, and two-member laterally bulb-surrounding and ballast-surrounding non-conductive housing means including a first one-piece housing member with a large flared open end to be sealed by a covering lens and with a small open end adapted to surround part of the lamp bulb, and a second one-piece housing member with a small open end to be covered by electrical screw-in means and with a large open end adapted to surround the ballast and overlap the small end of and be sealed to the first member.
Fluorescent lamp assembly comprising lamp bulb and ballast and first and second open-ended non-conductive housing members, each housing member having a large end and a small end, the large end of the second housing member overlapping the small end of the first housing member, wherein the ballast comprises a circuit board juxtaposed transversely against the small end of the first housing member, defining therewith and with the overlapping larger end of the second housing member an annular compartment, such annular compartment being adapted to accommodate ballast components mounted on the circuit board.
Sealed fluorescent lamp assembly with longitudinal axial symmetry, comprising a fluorescent lamp bulb and a solid-state ballast therefor, plus
- a reflective housing member laterally surrounding the bulb and having a flared light-emitting end with covering lens and a smaller opposite end, and
- an Edison hood having a small end with an electrical screw-in base and a larger opposite end overlapping and be sealed to the smaller end of the reflective housing member, defining an annular space therebetween adapted to accommodate solid-state ballast components therewithin.
Two-piece housing for a fluorescent lamp assembly with axial symmetry, comprising
- a first housing member with a flared large open end adapted to emit light when a lamp is therein and with a smaller open end, and
- a second housing member with a small end adapted to carry a screw-in electrical fitting and with a larger open end overlapping and juxtaposed to the first housing member about the smaller open end thereof,
- the overlapping ends of the respective housing members being non-conductive and defining therebetween an annular space adapted to receive a solid-state ballast therewithin.
