| 20080253000 | VEHICLE LAMP - 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. | 10-16-2008 |
| 20090073703 | OPTICAL AXIS INSPECTION METHOD AND OPTICAL AXIS INSPECTION APPARATUS - An optical axis inspection apparatus is provided with: a camera for capturing a light distribution pattern of a light source device projected on a screen; an image processing device for finding a cutoff line in the light distribution pattern; an acceptance reference cutoff line setting unit; and a shade having an oblong slit and arranged to be opposed to a projection lens of the projection type light source device. Whether or not an optical axis is proper is inspected based oh a shift of the cutoff line with respect to the acceptance reference cutoff line. Only a transmissive light passing through a substantially central portion in a vertical direction of a projection lens including an optical axis of the projection lens is guided onto the screen by the shade. | 03-19-2009 |
| 20090310353 | LAMP UNIT - A lamp unit includes a first light source; a projection lens that forms a light distribution pattern using light radiated from the first light source; a second light source; and a parabola optical system reflector that reflects light radiated from the second light source. The projection lens has a paraxial outer peripheral portion that is closer to a first optical axis than at least part of another outer peripheral portion as seen in the direction of the first optical axis. The parabola optical system reflector reflects light radiated from the second light source such that the reflected light passes through a space adjacent to the paraxial outer peripheral portion. | 12-17-2009 |
| 20100244649 | LIGHT EMITTING DEVICE MODULARIZING MEMBER AND LAMP UNIT - A LED is modularized by a light emitting device modularizing member. The light emitting device modularizing member includes heatsink having planar base, a LED mounting plate extending perpendicularly to the base from a portion closer to the end than to the middle portion of the base, and a light emitting device holder provided on each of a first face of the LED mounting plate, which is a face facing the middle portion of the base, and a second face of the LED mounting plate, which is a face opposite to the first face. | 09-30-2010 |
| 20100246204 | LAMP UNIT - A lamp unit includes a first semiconductor light-emitting element that serves as a light source; a second semiconductor light-emitting element that serves as a light source; a support member that supports the first semiconductor light-emitting element and the second semiconductor light-emitting element; a first reflector provided above the first semiconductor light-emitting element, which reflects light radiated from the first semiconductor light-emitting element forward; a shade that blocks a portion of reflected light from the first reflector; a projection lens provided in front of the first reflector with the shade disposed therebetween, which forms a light distribution pattern with a cut-off line from light reflected by the first reflector; a positioning portion that positions the projection lens; and a second reflector provided below the second semiconductor light-emitting element, which reflects light radiated from the second semiconductor light-emitting element forward. The shade, the positioning portion, and the second reflector are integrally molded as a composite part. | 09-30-2010 |
