Abstract

PURPOSE:To illuminate the ceiling in a stand state and the front floor at the normal time by providing a main body connected to the floor nozzle to be rotated freely with a lamp, and the top of the floor nozzle with a mirror. CONSTITUTION:The light from a lamp 7 on a lamp housing part 5 passes a lens 6 and reaches a mirror 8 on the inclination flat of a floor nozzle part 2 to light the ceiling. At the normal use, a part of light from the lamp 7 on the part 5 does not reach the mirror 8 and directly lights the floor in front of the floor nozzle 2 by the inclination angle of the tilted main body 1 rotated around a rotating axis 9. A part of light which reaches the mirror 8 can illuminate the remote floor and widely maintain the radiation range. By tilting the main body 1 deeper, the light from the lamp 7 on the part 5 passes the lens 6 but does not reach the mirror 8 and can directly illuminate the deeper part in front of the floor nozzle 2.
