<P>PROBLEM TO BE SOLVED: To solve a problem that in a conventional vehicular lighting fixture, the center part is not suitable for obtaining a light distribution pattern of a high light intensity. <P>SOLUTION: Two light emitting units 21, 22 for the lighting fixture are arranged vertically symmetrically holding the horizontal axis H-H between them. As a result of this, the light distribution pattern P1 (P2) obtained by a piece of light emitting unit 21 (22) for the lighting fixture is obtained as a light distribution pattern P in which the two are symmetrically synthesized. Since the two pieces of light distribution patterns P1 (P2) are symmetrically synthesized as for this light distribution pattern P, it has a high light intensity zone at the center part, and becomes to have a long light distribution pattern in the right and left on the horizontal line HL-HR. In this way, it has the high lighting intensity zone at the center part and is suitable to obtain the light distribution pattern P which is long in the right and left on the horizontal line. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
