  • Patent number: 8733991
    Abstract: A vehicle lamp is formed using a light guide body. Thus light with an excellent aesthetic quality can be emitted without increasing the number of components. The structure has a light guide part (6a) formed on a light guide member (6). The light guide part (6a) emits light in an elongated shape by irradiating a first light-emitting diode (9) provided on one end of the light guide part (6a) in the longitudinal direction. A projecting part (6g) projects reward on the rear face of the light guide part (6a), which is the light-emitting face. A light emission suppressing part (6h) is provided on the projection end face of the projecting part (6g) and has a metal film (6f) formed by vapor deposition.

  • Patent number: 8514064
    Abstract: A door mirror has a turn lamp that can be mounted easily and without an increased size. The turn lamp (2) has a housing (3) and an outer lens (4) that are formed by molding. A light emitting diode (6) is mounted in the housing (3), and the outer lens (4) covers the housing (3). The housing (3) and the outer lens (4) are integrated by a joint (7) produced by injection molding and placed at a butt section at which the housing (3) and the outer lens (4) are butted together. Steps (7c, 7d) are formed at the butt section integrated by the joint (7) of the turn lamp (2), and a lower end edge section (1c) and a left end edge section (1e) that form an opening (1b) of a body (1) of the door mirror (DM) are butted to the steps (7c, 7d).

  • Patent number: 7686487
    Abstract: A door mirror comprising a mirror portion and a side blinker which is one example of lamp bodies allows easily performed maintenance for the side blinker. It is also structured so as to make a lamp body elongated in lateral dimension. A second opening is formed on the back side of a mirror housing with fixing pieces formed on the second opening. A lamp unit integrates a lens portion with the back face of a base body having an inner base and an outer base which covers the front face of the inner base and is structured so that the base end side avoids the vehicle body mounting portion. The lamp unit is inserted into the second opening through the back face side of the mirror housing, and fixing pieces on the lamp unit and the mirror housing-fixing pieces are tightened by screws.

  • Patent number: 7540642
    Abstract: A vehicle lamp includes a lens portion; and a base housing incorporated with a light source portion, the base housing integrated with the lens portion in a butting condition. The light source portion includes first and second light sources, a substrate, a first light source terminal plate and a second light source terminal plate implanted in the substrate so as to create a gap from each other, and an electric or electronic component that turns on the first and second light sources. A front-end part of at least one of the light source terminal plates is bent toward the other light source terminal plate so as to differentiate the first and second light sources in an irradiating direction.
