The light bulb assembly comprises a light bulb, a socket for containment of the light bulb, and a light switch assembly for selectively providing current to the socket and attached light bulb. The light bulb has three filaments which separately emit white light upon selective illumination. Two of the filaments, however, are separately encased by a sleeve of translucent, differently colored material. Accordingly, the white light emitted by each of the latter two filaments is filtered by the colored sleeves, and these filaments thereby produce colored light. The switch assembly has three switches, each of which selectively illuminates one of the filaments. The light bulb assembly is thereby able to selectively provide white light as well as differently colored light on different occasions.

  • Patent number: 6633112
    Abstract: A filament array for an incandescent lamp comprises at least five filament sections (10) having their longitudinal axes parallel with one another and, when viewed in plan, being arranged substantially symmetrically in a polygonal configuration around the lamp axis. The filament sections are wound from a single wire and are electrically connected together in series by means of linking sections (18, 19, 20) of said wire extending between corresponding ends of the filament sections, with alternate linking sections being positioned at opposite ends of the filament sections. The linking sections at the two ends of the array are supported by a set of support members (30, 31) extending from respective frame members (34, 35). The electrical input and output (14, 15) of the array are through terminal wire sections on opposite or substantially opposite sides of the array.

  • Patent number: 6630770
    Abstract: A light source bulb in an automotive headlamp having a lamp chamber defined by a lamp housing and a lens, where the lamp chamber includes a reflector and the light source bulb arranged therein. The reflector includes a reflecting surface constituted by a complex reflecting surface. The light source bulb includes a high-beam filament arranged obliquely below and behind with respect to a low-beam filament. When lit, high and low beam distribution patterns are formed by entire-surface reflection light distribution control of the reflecting surface. The light source bulb is used for right traffic and for left traffic. A second support wire is, in a side view of said light source bulb, bent to rearward of the rear end of said high-beam filament and positioned above the lower end of said low-beam filament.

  • Publication number: 20030030358
    Abstract: This invention relates to a long bulb structure, which includes a long glass shell being provided with two or more sunken circular areas. The inner surface of the sunken circular area may contact two conductive wires to maintain them in a right position in the glass shell and to prevent tungsten wires connected between the conductive wires from teaching the glass shell. The glass shell is thus avoided from being heated and broken and the bulb can be used in secure.

  • Publication number: 20020041139
    Abstract: A portable lamp with adjustment device to obtain different emitted light cones includes a light source received within a concave reflector. The light source includes at least two separately switchable incandescent filaments operatively connected to a power source, which are arranged within the light source to generate a desired light cone. By way of example, according to the invention, a filament intended to generate a small angled light cone, i.e. for far distance illumination, draws greater power from the power source than a filament intended to generate a wide angled light cone. To this end, each of the filaments has different illuminous efficiencies. An additional laser light source, electronic flash unit controlled by the light source may also be provided.

  • Patent number: 5850124
    Abstract: In an automobile lamp bulb, a shield is attached firmly to a common conductor by an improved fixing method. Dents are formed in one surface of a shield to form projections in the other surface of the same and a cut is formed in the shield. Portions of the shield defined by the cut are raised to form lugs, and projections are formed, respectively, on the lugs. A projection is formed in each lug which corresponds to the dents, but project in opposite directions. The projections of the shield are welded by projection welding to the common conductor to join the shield firmly to the common conductor. Therefore, an inexpensive rough service automobile lamp bulb is provided. In another embodiment, a portion of a round common conductor is flattened to form a flat portion. A shield is positioned on and welded to the flat portion of the common conductor. Since the shield is positioned on and welded to the common conductor in surface contact, the amplitude of vibration of the shield can effectively be suppressed.
