<P>PROBLEM TO BE SOLVED: To provide a luminaire capable of widely illuminating the circumference by covering an illuminating light source with a light-diffusing balloon having flexibility, of providing independence to the balloon itself, and of stably keeping the attitude of the balloon even if the luminaire is tilted. <P>SOLUTION: This luminaire is provided with a grounding part 1, and the illuminating light source 3 arranged continuously to the grounding part 1, and can return to the original grounding attitude from a tilted attitude by gravitational force acting on the gravity center of the grounding part 1 even when it is tilted with the grounding part 1 and the light source 3 set on the lower side and on the upper side, respectively. In the luminaire, the light source 3 is covered with the bag-like light-diffusing balloon 13 having flexibility, and the balloon 13 is expanded in a nearly inverted conical shape in the profile by blowing air into the balloon 13 by a balloon-expanding fan 7. <P>COPYRIGHT: (C)2008,JPO&INPIT |
