  • Patent number: 6325651
    Abstract: A light emitting device (1) includes a tubular light emitter (11) and a pair of caps (14) disposed at both ends of the tubular light emitter. Each cap (14) includes a contact (24) and a pair of catching arms (27) both which of which project from the cap body (22) at approximately a right angle to the tube axis of the cap body (22). During assembly, catching arms (27) serve to protect contact (24) from damage and securely attach each cap (14) to the tubular light emitter. Each cap (14) includes a partition wall with a hole (30) connecting a conductive element (21) to contacts (24). The light emitter (11) may include a tube (12) containing one or more light elements (15) joined by wires (16) additionally operating as positioning elements (20). The socket (2) may include one or more groves for gaskets (42) providing a waterproof light emitter (11).

  • Patent number: 6234649
    Abstract: An electric lamp device which is capable of suppressing obstruction light toward the sky even if being used as a garden light or the like as well as a common lighting electric lamp. In the electric lamp device comprising an envelope and a small-sized light-emitting element assembly, an open end of a globe is coupled to a globe connection opening of a base body to constitute the envelope, and the small-sized light-emitting element assembly, such as a set of baseless small-sized electric lamps connected in series to each other, is housed within this envelope, and additionally, a louver including ring-like louver components is put within the envelope surrounding the small-sized light-emitting element assembly. Further, when needed, an attachment is fixed in the globe connection opening of the base body. The louver is mounted on this attachment. The attachment is composed of a plate section, a light-emitting element mounting section, and a support standing section.

  • Patent number: 6153972
    Abstract: A globe (11) and a substrate (12) form an outer shell (1). In the outer shell (1), there is arranged an attachment (3) having an electric lamp mount (32) and a support stand part (33). In the electric lamp mount (32) of the attachment (3), there is arranged a serially connected body of no-base type small electric lamps (4), and at the support stand part (33), there is arranged a support body (5). The serially connected body of no-base type small electric lamps (4) has a plurality of no-base type small electric lamps (51) and conductors (52) for serially connecting these no-base type small electric lamps (51), is composed by gathering these plurality of no-base type small electric lamps (51). The support body (5) supports the serially connected body of no-base type small electric lamps (4).

  • Patent number: 6095660
    Abstract: The present invention relates to a fixture to be mounted in a mounting hole in a ceiling or the like and an attachment device of said fixture, wherein said fixture is provided with an electrical connection means and a mechanical stopping means, the electrical connection means including a power supply port that can be connected by a simple operation, and the mechanical stopping means capable of removably fixing a heavy and elongated fixture in the mounting hole, so that, when the fixture is mounted in the mounting hole, both electrical and mechanical connection is simultaneously done. By an integrated design of the fixture wherein the back of the mounting hole (a space behind the ceiling panel or the like) is used as a housing space for a lighting circuit member, etc., the fixture can be made more compact with an improved design flexibility, and changes and movements of fixtures with respect to the mounting hole become possible.
