Abstract: A method for manufacturing a vehicular lamp including a wire installation process that installs a wire (hearing wire) 6 in a flat resin plate 7 by heat; a shape-forming process that forms the resin plate 7 into a predetermined curved shape; a trimming process that trims the resin plate formed in the predetermined curved shape into a desired shape of the exterior contour of a front lens 3; and a fixing process that fixes the front lens to a lamp body 2 by optical welding.

Abstract: A vehicular lamp 1 including a lamp unit 2, in which a light-emitting diode 2a is used as the light source, and a cover member 4, which is provided between the lamp unit 2 and an outer lens 3 of the lamp and located near the inside surface of the outer lens 3 so as to cover the lamp unit 2 except its light-emitting region. The cover member 4 is formed of a material that has good heat conductivity, and heat generated by the light-emitting diode 2a is transferred to the cover member 4 and to the outer lens 3, thus heating the outer lens.

Abstract: As the annular translucent member, an annular lens formed from a peripheral edge portion of a convex-meniscus lens is disposed between a projection lens and a reflector along an outer peripheral edge of the projection lens. Direct light from a light source toward a space beyond the outer periphery of the projection lens is caused to illuminate forward of the lamp by the annular lens, thereby effectively utilizing light source luminous flux. In relation to the above, a shape of a back surface of the annular lens is formed into a spherical surface having its center at a luminescence center of the light source. Accordingly, direct light from the light source can travel straight without being deflected by a back surface of the annular lens, whereby a light deflection angle on a front surface of the annular lens can be calculated easily and with good accuracy.

The vehicular lamp thus manufactured is provided with a front lens that has a wire-installed resin plate therein as the light emission surface portion.

Abstract: A projection-type vehicular headlamp structure that is capable of forming at least two types of light distribution in at least two modes, and is also capable of controlling the radiated light thereof with high precision in addition to keeping to a minimum any noticeable difference when switching between modes. A portion of a reflector is structured as a mobile reflection portion which may separate from a remaining reflective portion. An additional reflector is disposed generally behind the mobile reflective portion. The additional reflector is incident to light from a light source when the mobile reflective portion is separated from the remaining reflective portion. Light incident from the mobile reflective portion, the remaining reflective portion, and the additional reflector is reflected forward to a projection lens of the vehicular headlamp, providing illumination in the area preceding a vehicle's traveling path.
