Abstract: An optical assembly includes a first reflector having a reflective surface with a first lateral extent, and a second reflector having a reflective surface with a smaller, second lateral extent. The second reflector is disposed such that the second reflective surface opposes the first reflective surface with a space therebetween. A light emitter couples with the first reflector such that the light emitter emits light along a central axis, away from the first reflector and toward the second reflector. A translucent diffuser substantially spans the space between the first and second reflectors. A majority of the light emitted by the light emitter reflects from the first and second reflectors, and impinges on and passes through the diffuser. A luminaire that includes the optical assembly also includes an outer shell having a form that is analogous to a shape of the diffuser of the optical assembly.

Abstract: A light assembly including a socket, a housing, and a mounting member. The socket is connected to the mounting member, which is pivotably secured to the housing and constructed to allow rotation of the socket, and thereby a lighting element engaged with the housing, relative to the housing.

Abstract: A lighting fixture is disclosed that has two lights sandwiching a pivotable reflector. An upwardly directed lamp is mounted on the reflector to pivot therewith. The down lamp may also be mounted on the reflector to pivot therewith, albeit it need not be. A lower shade can enclose the down lamp. To replace the lower lamp one can pivot the reflector to provide access to the burnt-out lamp.

Abstract: A lighting unit for illuminating a wall and adjacent ceiling area. The lighting unit includes a primary reflection element having a curved portion and a smoothly coupled planar portion. A light source is positioned within the lighting unit and a diffuser element can be used to obtain a desired illumination distribution.

Abstract: A yellow gold alloy which resembles 10 karat gold in appearance and physical properties but has a gold content substantially less than 10 karat gold. The alloy consists essentially of 11% to 16% by weight gold, 28% to 34% by weight silver, 30% to 38% by weight copper, 8% to 12% by weight palladium, 7% to 10% by weight zinc, 0.2% to 0.4% silicon, and about 0.02% boron, and is particularly well suited for use in the manufacture of rings and other jewelry articles.
