Abstract
A reflector is for reflecting light rays from the light source bulb to set up a brightness intensity distribution pattern. The reflector is separated in a movable reflector part and a fixed reflector part. The movable reflector part has a first separated edge. The fixed part has a second separated edge in opposition to the first separated edge. A driving means is for moving the movable reflector part relative to the fixed reflector part to change a brightness intensity distribution pattern of light rays from the light source bulb. The shading flange is for shading an air gap between the first separated edge and the second separated edge.
