摘要：<p>PROBLEM TO BE SOLVED: To provide a balloon type luminaire which maintains a shape of a balloon, which generates an airflow necessary for cooling a light source and a power source control circuit and the like for lighting it stably, and which can be used both outdoors and indoors by suppressing noise when used indoors.SOLUTION: A balloon type luminaire 1 includes: a balloon 2; a blower 3 for inflating the balloon 2; a light source 4 arranged inside the balloon 2; and a power source control circuit 5 for driving the light source 4 and the blower 3 and arranged in a blowing path of the blower 3. The balloon type luminaire 1 also includes blowing capacity switching means 20 for switching the blowing capacity of the blower 3 at least in two steps. When the blowing capacity of the blower 3 is switched to the minimum by the blowing capacity switching means 20, noise to be generated is equal to or less than 50 dB, and air pressure difference between inside and outside of the balloon 2 is equal to or more than 0.4 hPa.</p>
