发明名称 LAMP UNIT FOR VEHICLE HEADLIGHT
摘要 <P>PROBLEM TO BE SOLVED: To provide a vehicle headlight which can provide an ideal low beam distribution pattern in a single unit. <P>SOLUTION: A light distribution pattern LB from a third reflecting surface M3 has a horizontal cut line CL2 of which the upper edge is almost horizontal, and a light distribution pattern HZ from a second reflecting surface M2 includes a hot spot part HS which laps in the light distribution patter LB of the third reflecting surface M3 and a projected part OS which projects into an upper side over the horizontal cut line CL2 of the light distribution pattern LB from the third reflecting surface M3 and has an inclined cut line CL1, and a distribution pattern OP from a fourth reflecting surface M4 emits a light from an LED3 for an overhead sign. Since an ideal low beam light distribution pattern can be obtained in a sing unit, an assembling work can be done easily and the unit can be made smaller. <P>COPYRIGHT: (C)2008,JPO&INPIT
