Abstract: A lamp (100) comprises an outer envelope (120) having first and second electrical lead-ins (140, 160) sealed into a base (180) of the envelope (120). A ceramic arc tube (200) is operatively mounted within the envelope (120), the arc tube (200) having at least one electrode (220) therein. A tubular, niobium feed-through (240) is connected to the at least one electrode (220) and sealed to the ceramic body (120) at a joint (260) that can comprise a glass frit (260a). A stainless steel rod (280) is electrically connected between the electrical lead-in (140) and the tubular niobium feed-through (240), the stainless steel rod (280) being the only electrical connection between the lead-in (140) and the niobium feed-through (240).

Abstract: An integral HID reflector lamp may be formed with an HID held in a reflector. An inner element is mechanically coupled to the reflector. The inner element is formed with a first mechanical coupling to mate with the reflector, a second mechanical coupling to mate with a circuit board, and an electrical coupling to at least electrically couple one of the leads to the circuit board. A circuit board has an edge mechanically coupled to the inner element and electrically connected to the leads by an electrical coupling on the inner element. A heat sink spans at least one side of the circuit board and forming an EMI shielding. An outer cover encloses the heat sink, circuit board, and inner element and coupled to the assembly of the reflector, HID lamp, inner element, and heat sink with each elements of the assembly clipped together.

Abstract: A lamp may be formed with radial arm electrical contacts from a ceramic body insulating body supporting a lamp capsule. A press sealed tubular lamp is held in an end of the ceramic body. The radial arms extend sideways from the ceramic body and support electrical contacts, that may be brought into electrical contact in an insert and twist type socket.

Abstract: A semi-standard threaded base lamp assembly may be formed with a substitutable optical housing. The assembly enables a standard set of components to be assembled as a threaded base lamp, but during construction any one of a variety of specialty reflector shells may be substituted in the assembly process to specialize the lamp for a particular market, need or interest.

Abstract: A lamp includes a reflector having a passageway opening to a heel of the reflector, a lamp capsule having a lead that extends rearward through the passageway, a conductive clip that spans a diameter of the heel and that has tabs that extend forward at opposite sides of the heel and an arm that extends rearward, the arm being attached to a portion of the lead that projects out of the passageway, and a base that is attached to the heel and that engages the tabs at the opposite sides of the heel. The arm holds the lamp capsule in place and electrically connects the lamp capsule to the base. The arm may be a semi-detached central portion of the clip that is bent to be substantially parallel to an axis of the lead.

Abstract: An exterior automotive lamp may be formed with LED light sources by efficiently using the available light. The LEDs are arranged in an array to illuminate a central lens to produce the horizontal spread from the central portion of the LED beam. Meanwhile a reflector gathers the more disperse side-emitted portion of the LED beam and directs that light as an outer sheath to form a supplementary portion of the beam. The lamp efficiently provides a beam that may be adapted for highbeam, lowbeam, fog, or signal purposes.

Abstract: An advanced forward lighting system may be made with a lamp having a first filament and a second filament extending perpendicular to the first filament. The second filament is partially hidden rearward and above the first filament. A reflector forms a main beam from the first filament light and a right or left cast supplemental beam from the second filament light. The second filament's position minimizes glare, and enables a simple advanced forward lighting system from a single standard lamp fitting both right and left side reflectors.
