ABSTRACT:
The method of designing a reflective surface of a reflector in a vehicle lamp according to the present invention comprise (1) a segment creating step of sectioning a free curved surface and creating a plurality of segments having a plurality of vertexes, and (2) a curved surface generating step of deciding the light reflecting direction at each one of the plurality of vertexes, and generating curved surfaces to be assigned to the segments based on the reflecting direction for each one of the plurality of segments. The present invention provides a method of designing a reflective surface of a reflector in a vehicle lamp whereby the controllability of the luminous intensity distribution pattern is improved.
