<p>A reflector is for reflecting light rays from the light source bulb (1) to set up a brightness intensity distribution pattern. The reflector is separated in a movable reflector part (3) and a fixed reflector part (2). The movable reflector part (3) has a first separated edge (31). The fixed part has a second separated edge (21) in opposition to the first separated edge (31). A driving means (6) is for moving the movable reflector part (3) relative to the fixed reflector part (2) to change a brightness intensity distribution pattern of light rays from the light source bulb (1). The shading flanges (22,32) are for shading an air gap between the first separated edge (31) and the second separated edge (21). <IMAGE></p> |
