Multiple triangularly shaped concentric annular fluorescent tubes for reflective lamps

Abstract

Multiple concentric, triangular cross-sectioned fluorescent lamp tubes, located substantially in the same plane with respect to each other, are utilized in appropriate assemblies for: 1) a direct screw-in replacement for reflective incandescent lamps and; 2) recessed ceiling fixtures that are typically hardwired. The inherent triangular geometries of the concentric, substantially same plane lamps create mutually benefiting reflecting surfaces to maximize the net light output. The triangular geometry enables light from two sides of the fluorescent tubing to be efficiently cast if desired (or muted by absorbent housing wall if desired). The remaining side, or base, of each triangular tube produces light that is redirected by opposing, intersecting, coaxial, conical reflectors arranged to direct the light through the unobstructed center of the concentric tubing arrangement. A transparent collimating structure adjacent to the triangular tub bases is used to enhance control of the light emanating from the base. The arrangement is incorporated in a single assembly with an Edison screw-in base and as lamp assemblies for use in hardwired fixtures.
