Technology: Light balloon begins to take off - translucent polyester film
Both film directors and civil engineers should be thankful for the balloons that are lighter than the air.
The balloon, called Lunix, is not only filled with helium, but also has powerful internal lights.
Developed by Airstar, a small company based near Grenoble, the balloon can provide unobtrusive lighting at movie sets, construction sites, sporting events and even amusement parks. It weighs 1.
5 kg, can be packed and moved easily.
For many events, the lamp in the balloon is more convenient than the spotlight mounted on the scaffold.
So far, the company has built two versions with a diameter of 1.
5 m, another 2-metrediameter.
There are halogen lamps and 2-
The rice balloon can provide 4 KW lighting.
The balloon itself is made of translucent polyester fabric, similar to the parachute material, which provides a uniformly distributed light source.
There are two lines between the balloon and the ground.
One line supplies power to the lights and the other is tied with balloons.
Inside the balloon is a sensor that can check any changes in the shape of the balloon.
If the helium is lost and the balloon deflates, the sensor will cut off the power supply.
The company is currently working on a larger version of the balloon that will contain arc light designed to reproduce daylight for movie tycoons who like to shoot daytime scenes in the dark.
