Patent ID: 7134774

Claim:
A projector type vehicular lamp device comprising: a light source provided near a first focus of a concave mirror; a convex lens modulating a light flux outgoing from the light source and reflected by the concave mirror to an approximately parallel light flux so as to emit to a front side of the light device; and small reflectors for forming a cutoff line and small reflectors for not forming the cutoff line, wherein the small reflector for forming the cutoff line includes an upper reflector in which the small concave mirror is integrally formed, and a lower reflector which integrally forms a shade including an approximately horizontal reflection surface extended to a rear side from a front end of a bent edge portion formed along a meridional image surface, and a front end step portion formed by being notched in a band shape from an approximately center portion in a width direction of the reflection surface to one side front end in one side along the bent edge portion, and is connected to the upper reflector from a lower side, wherein the small reflector for not forming the cutoff line includes an upper reflector in which the small concave mirror is integrally formed, and a lower reflector which integrally forms a shade including an approximately horizontal reflection surface extended to a rear side from a front end of a bent edge portion formed along a meridional image surface, and is connected to the upper reflector from a lower side, wherein the small reflectors for forming the cutoff line and for not forming the cutoff line respectively structure small projector type lamp devices for forming the cutoff line and for not forming the cutoff line by combining the upper reflector and the lower reflector in such a manner that the bent edge portion is positioned near a second focus of the small concave mirror, pinching the small convex lens between the upper reflector and the lower reflector, and fixing the light source to the upper reflector, and wherein the small projector type lamp devices for forming the cutoff line and for not forming the cutoff line are incorporated into a housing.
