Abstract
A lighting equipment including illuminating lamps that automatically turn outward when an illuminating portion supporting the lamps is directed directly downward at an elevation angle of −90°. When the elevation angle of the illuminating portion is at a predetermined angle or more, the elevation angle of the illuminating lamps is maintained at substantially 0°, and the normal direction of the illuminating portion substantially matches the irradiation directions of the illuminating lamps. The elevation angle of the illuminating lamps is varied and maintained by link mechanisms mechanically interlocking with the pivoting of illuminating arm portions.
