This paper is concerned with a lighting system for lighting a working area, said lighting system shown at figure 1, includes at least a luminous device arranged on a frame fixed at a balloon anchored to the ground and adapted to lift the frame up into the air. The lighting system can be installed quickly and can, moreover, being used on rough, snow-covered, or muddy terrain.

This paper is concerned with a lighting system for lighting a working area, said lighting system shown at figure 1, includes at least a luminous device arranged on a frame fixed at a balloon anchored to the ground and adapted to lift the frame up into the air.
The lighting system can be installed quickly and can, moreover, being used on rough, snow‐ covered, or muddy terrain.
It is known to use lighting systems distributed around a working area in order to light the aforementioned area. Each lighting system includes a tripod posed on the ground and carrying at

its end one or more luminous devices thus placed in height. The luminous devices are directed towards the ground and powered by an auxiliary power unit in order to light a broad surface of the working area.
The use of the tripod equipped lighting systems can only be done on flat terrains.
The lighting system according to this paper is an alternative to the one of former art and includes a frame interdependent of a balloon fixed via a cable of attachment at one rig on the ground, at least a luminous device arranged on the frame, and a power supply providing, via an electric
cable, electricity required for the operation of the at least luminous device.
The rig could be formed by the power supply and the electric cable could in that case replace the cable of attachment.
The balloon has an envelope intended to be filled with gas (helium for instance) of density smaller than that of the air, and comprises for this purpose an admission valve by which an operator can fill the balloon with gas, by using for example a gas carboy. It will be noted that the balloon also comprises a safety valve making it possible to evacuate a gas overflow when the value of the gas pressure into the envelope exceeds a limit value. The dimensions of the balloon are calculated so
as to the latter can rise up in the air bearing the frame once its envelope is filled with of an adequate volume of gas
A fishnet preferably surrounds the balloon's envelope in order to bear the frame and to prevent any strain of envelope when the balloon is inflated, in particular if envelope is non‐rigid. ...
