  • Publication number: 20080253000
    Abstract: A vehicle lamp includes a lens formed from a resin material and a lens holding member for holding the lens formed from the resin material. The lens and the lens holding member are adapted to be joined together through laser welding. A joining annular portion is provided on the lens holding member to which an outer circumferential portion of the lens is joined. A plurality of welding portions and a plurality of stopper portions are provided on the joining annular portion. The plurality of welding portions project towards the lens and are positioned apart from each other in a circumferential direction. The plurality of stopper portions project towards the lens, are positioned apart from each other in the circumferential direction, and contact the outer circumferential portion of the lens when the lens is joined to the joining annular portion.

  • Publication number: 20070133220
    Abstract: A vehicle lighting device with a lamp compartment having a light source unit disposed therein. The light source unit includes a light emitting device as a light source and a projection lens as a light distribution control member for distributing light. A face bearing portion at a distal end of a lens mounting portion of the light emitting device corresponds to a rear surface of a collar portion disposed along an outer circumference of the projection lens. Complimentary extending projections and stepped portions on the collar portion and lens mounting portion are ultrasonically welded together, and burrs formed during the welding process are prevented from protruding toward the optical axis by an erect wall of the stepped portion.

  • Publication number: 20060146555
    Abstract: A vehicular lamp installed in a sideview mirror housing 10 that has a laterally extending opening 12. The vehicular lamp has a horizontally curved shape and is installed in the housing 10 such that the entirety of its front lens 24 is substantially flush with and exposed through the opening 12. An LED 26 and a light guide inner lens 27 are installed inside a curved and laterally elongated lamp chamber space S which is defined by the lamp body 22 and the front lens 24. The LED 26 for illuminating the entire light guide inner lens is disposed on a curved wrap-around side of the lamp chamber space S so as to face the vehicle forward direction, and another LED 29 is provided in the vehicle width outward direction so that it distributes emitted light in a predetermined direction directly or via a reflector 34.

  • Patent number: 6004498
    Abstract: A resin part such as an instrument panel, a console box or door trim has a substrate body made of hard resin and a skin mounted on a surface of the substrate. To produce the resin part, a preformed elastic sheet is set within a mold cavity. Then, a molten resin is injected into the cavity through gates. The molten resin is first injected into the cavity through gates that are opposed to the skin and after the passage of a predetermined time, the resin is injected through gates that are not opposed to the skin, thereby forming a substrate that has the skin thermally fused to a surface thereof.
