Abstract
A multifunctional member and reflector lamp employing same for mounting a light-source capsule on the inside of the neck of the outer envelope, for optically aligning the capsule with respect to the reflector, for reflecting heat away from the base region of the lamp, for blocking convective heat transfer into the lamp neck, and for reflecting light incident on the member toward the lens. In performing these multiple functions, the member reflects heat back to the filament or light source which improves its efficiency, and the member redirects light toward the lens which improves the efficacy of the lamp. In a preferred embodiment, the multifunctional member is formed from stainless steel and has a bowl-shaped body with a somewhat flexible peripheral annular tab extending upward and outward conically. The peripheral tab may be crimped, slotted, or have a tapered thickness in order to provide flexibility sufficient for mounting. The bowl-shaped body preferably is paraboloidal having a focal center substantially coincident with the focal center of the reflector. In an alternate embodiment, the multifunctional member has a curvature matched to the curvature of the reflector and no peripheral tab so that the reflector has been optically extended to the press seal of the light-source capsule. A lamp constructed in accordance with the invention is particularly well suited for employing a heat-sensitive component, such as a diode, in the base region of the lamp.
