Abstract
A lighting device can include a light shielding plate configured to impart a required or desired light distribution pattern by shielding light received directly from a light source and/or light reflected from a reflector. The light shielding plate can be configured to be movable between at least two predetermined positions so as to impart at least two light distribution patterns to the projected light. The movement of the light shielding plate can be achieved by rotation about a vertical rotary shaft.
