LIGHTING SYSTEMS FOR PRODUCING DIFFERENT BEAM PATTERNS
摘要
A lighting system (20) includes a light source (21), a diffusing optical element (27), and projection optics (23). The diffusing optical element (27) is located between the light source (21) and the projection optics (23), and is movable along an optical path (25) to alter the beam pattern produced by the system (20).
