LIGHT PROJECTOR

A light projector comprising a generator (6), a truck (1) mounted with the generator, an expandable pole (2) erected on the truck, a balloon (4) equipped on the upper end of the expandable pole, and an illuminator (3) built in the balloon. The generator can feed power to the illuminator. The illuminator is operated by supplying power from the generator mounted on the truck, and the light is converted into soft light through the balloon to project the soft light omnidirectionally outside the balloon. Even when the light projector is used for night-time illumination for road construction or the like, drivers of vehicles passing nearby do not dazzle thereby, and the light of the illuminator can be projected widely.
