A vehicular lamp having a combination lamp structure in which the reflectors for a plural number of lamps and an extension reflector are provided in a lamp body, wherein a reflector for at least one lamp of the plural number of lamps and an extension reflector are constructed as a single body. Of the reflectors for the lamps, the reflector fixedly mounted on the lamp body and the extension reflector are preferably constructed as a single body. A specific reflecting portion for reflecting light from a bulb toward a lens area located apart from the bulbs of the lamps is formed as a part of the reflector. For example, a lamp of which the lens is partly extended to the side of a vehicle body, and a specific reflecting portion for reflecting light from the bulb toward a lens area of the lens extending to the side of the vehicle body is formed as a part of the reflector of the lamp.
In a vehicular lamp in which a plurality of lamps and reflectors for each of said lamps are provided in a lamp body, and a lens is mounted on an opening of the lamp body and in which said lamps include at least one front lamp and a side lamp for illuminating a side portion of the vehicle, a far-most side portion of said side lamp extending substantially rearwardly of a bulb for said side lamp, the improvement wherein a reflector associated with said side lamp includes a non-planar reflecting portion disposed forwardly of said lamp for reflecting light emitted from said bulb towards said far-most side portion to thereby illuminate said side portion of said vehicle and supply heat to an associated far-most side portion of said lens.
In a vehicular lamp in which a plurality of lamps and reflectors for each of said lamps are provided in a lamp body, and a lens is mounted on an opening of the lamp body and in which said lamps include at least one front lamp and a side lamp for illuminating a side portion of the vehicle, a far-most side portion of said side lamp extending substantially rearwardly of a bulb for said side lamp, the improvement wherein a reflector associated with said side lamp includes a non-planar reflecting portion for reflecting light emitted from said bulb towards said far-most side portion to thereby illuminate said side portion of said vehicle and supply heat to an associated far-most side portion of said lens, said reflecting portion comprises a plurality of v-shaped projections.
In a vehicular lamp in which a plurality of lamps and reflectors for each of said lamps are provided in a lamp body, and a lens is mounted on an opening of the lamp body and in which said lamps include at least one front lamp and a side lamp for illuminating a side portion of the vehicle, a far-most side portion of said side lamp extending substantially rearwardly of a bulb for said side lamp, the improvement wherein a reflector associated with said side lamp includes a non-planar reflecting portion for reflecting light emitted from said bulb towards said far-most side portion to thereby illuminate said side portion of said vehicle and supply heat to an associated far-most side portion of said lens, wherein said non-planar reflecting portion is disposed on an inside of said lamp and said far-most side portion is disposed on an outside of said lamp.
