Abstract
A first reflection surface of a reflector is set up for a first brightness-intensity distribution pattern to be projected through a flat lens to conform to a target brightness-intensity distribution pattern. A displacement between the target brightness-intensity distribution pattern and a second brightness-intensity distribution pattern is calculated, the second brightness-intensity distribution pattern being reflected by the first reflection surface and to be projected through a curved lens. A second reflection surface of the reflector is set up for the displacement to become substantially a zero.
