Abstract: A tungsten-halogen lamp for use in an automobile headlight comprises a tubular sealed glass capsule containing two coiled tungsten filaments for high and low beam operation, respectively. The low beam filament is disposed substantially orthogonal to a vertical plane containing the lamp axis, with the center of that filament length having a predetermined offset from that vertical plane and being disposed at or near the focal point of the reflector. The high beam filament is disposed substantially parallel to the lamp axis on the opposite side of the vertical plane from at least a major portion of the low beam filament. The filaments are spaced apart with the high beam filament lying in a horizontal plane spaced below the low beam filament, and the axis of the high beam filament orthogonally intersects a plane containing in the axis of the low beam filament.

Abstract: An inner-bulb assembly for use in an automotive lamp unit such as a headlamp or foglamp unit comprising an inner-bulb, an electrically nonconductive base and a metallic spring clip. The base can be designed to retrofit an H3 type of base. Additionally the metallic spring clip serves to secure the assembly to the rest of the lamp unit and as an electrical conductor for one of the inner-bulb pin leads.

Abstract: To permit introduction of a halogen incandescent lamp into a reflector, in ealed relationship thereto, a plastic end portion (2c) of the base (2) of the lamp is secured to a metal sleeve, for example of steel, which is telescopically connected to an adjustment cap (2a) in which the bulb (1) is seated. After adjustment of the position of the bulb, so that the filaments will emit light in a predetermined pattern with respect to the base, the adjustment cap and the sleeve are welded together. The plastic portion includes a groove (9) in which a sealing ring (10) for example of silicone rubber is placed, the plastic element including therebeyond a positioning or seating flange (11). The plastic end portion, thus, can readily be assembled with a glass reflector, the sealing ring (10) providing for a moisture tight seal against, for example, a glass reflector.

Abstract: The power/switcher module, bi-filament light bulb, and light bulb socket, of this invention are assembled with standard lamp industry hardware and fittings to provide a lamp fixture with conventional utility increased by the addition of an integrated automatic emergency lighting capability. Normal ON/OFF use of the lamp, while connected to household line current, also provides light bulb filament current for maintaining a full charge on a rechargeable storage battery. The loss of charging current through line current power failure, filament burn out, or selective disconnection by removal of the portable cord, immediately switches on the other filament to battery power, extending the emergency use to that of a portable lantern. Restoration of line current and/or a burned out filament automatically reverts the lamp to normal operation.

Abstract: The invention relates to a socket for a baseless cartridge lamp, particularly a two-filament cartridge lamp or a cartridge halogen lamp with contacts at opposite ends thereof.

Abstract: A tungsten-halogen incandescent lamp which includes a vitreous envelope, an inert gas and halogen fill, and two pairs of straight, parallel lead-in wires retained within the envelope's press-sealed end, each of said pairs having a tungsten filament supported thereon within the envelope. The pairs of wires occupy respective parallel planes within the press-sealed end with one pair laterally offset from the other. A method for making the lamp is also disclosed, in addition to a vehicle headlight particularly suited for utilizing the lamp.

Abstract: Precise placement of one or more coiled filaments within the envelope of a miniature type incandescent lamp is achieved by positioning the coil legs in end-to-end abutting relationship with the respective lead wires and locking them in such junctured relationship with metal tubes that enclose and are fastened to the abutted end portions of the mated lead wires and coil legs and thus couple the members together. The coupling tubes are first secured to the lead wires so that their open ends provide tubular pockets which receive the coil legs and guide them into the proper mounting position on the lead wires. The open ends of the tubes are then hot-clamped around the associated coil legs, thereby mechanically and electrically joining the members together in operative relationship. The invention is particularly useful in the production of miniature halogen-cycle type incandescent lamps that are employed as compact light sources in sealed-beam automotive lamps which require one or more precisely-mounted filaments.

Abstract: A traffic signal having a light which includes lens means formed with perforations extending through the lens means and arranged in a predetermined pattern whereby light transmission through the lens means in accordance with the pattern facilitates recognition of the signal by oncoming motorists. The perforations are formed in the lens itself or in a cover member or cap for the lens. The invention is particularly useful for color-blind persons or persons who have impaired vision. In one form of the invention a plurality of the signals are arranged on a traffic standard with sequentially actuated lights, while in a second form the signal is mounted on the rear portion of an automobile to supplement or replace the conventional taillights.

Abstract: An illuminated flag or pennant adapted to be affixed to the radio antenna of a moving vehicle such as a boat or automobile and is adapted to receive electrical energy therefrom includes means of coupling to the source of electrical energy and a fiber optic cable which couples electrical energy which has been converted to light energy to the flag at selected areas forming predetermined indicia which may be the radio operators call letters or handle.

Abstract: A signal device is usable with motorcycles or the like to identify the presence and direction of motion of the vehicle in limited visibility situations. A mast extending upwardly from the vehicle supports the signal lamp assembly above the vehicle. A pair of transparent domes secured on the signal lamp assembly in a forward-rearward relationship with respect to the vehicle enclose separate lamps. The domes are color-coded so that the forward and rearward ends of the vehicle are identifiable without actual visual contact with the vehicle. The signal device circuit may be interconnected with the vehicle indicator circuits so as to be operable therewith. The mast may be telescopically extended to provide greater ranges of visibility.
