发明名称 VEHICLE LIGHTING FIXTURE
摘要 <P>PROBLEM TO BE SOLVED: To provide a vehicle lighting fixture of a projector type, in which, even when failure occurs in a portion of a reflection surface of a reflector, deterioration of visibility due to the above failure is effectively suppressed. <P>SOLUTION: Basic light distribution patterns PL0, PH0 substantially the same as lighting fixture light distribution patterns PL, PH are formed by reflection light from other general reflection regions excluding a partial reflection region in a reflection surface of a reflector. Further, the above partial reflection region is so structured that the light from a light source may be incident as a diffusion reflecting light into a projection lens and additional light distribution patterns PLA, PHA which have broadening to some extent by the reflecting light may be formed. With this, even if a portion of the general reflection region causes a failure and a dark zone DZ is formed on a portion of the basic light distribution patterns PL0, PH0, this dark zone DZ is covered by the additional light distribution patterns PLA, PHA and, thereby, a portion of the lighting fixture light distribution patterns PL, PH is prevented beforehand from becoming extremely dark. <P>COPYRIGHT: (C)2013,JPO&INPIT
