Abstract
An illuminating balloon with an inflatable envelope contains an illumination system having at least one electric light bulb, and inflating means equipped with an integrated fan designed to suck air in from the outside and to inject it into the envelope while keeping the latter in the inflated state. The assembly formed by the bulb and fan is covered by a bowl made of transparent or translucent plastic material, forming an explosion-proof isolating shield and a deflector of the discharge air for inflation of the envelope via passage apertures provided in the bowl.
