Abstract
A light projector includes a power generator; a bogiefor mounting the power generator; an extendable or retractable supporting columnvertically installed at the bogie; a balloonarranged at an upper end of the extendable or retractable supporting column; and a lighting instrumentstored in the balloon, wherein the power generatorand the lighting instrumentcan be electrically energized. The lighting instrumentis lit through supply of electricity from the power generatorinstalled at the bogieand the light thus generated is changed into a soft-feeling light through the balloonso as to enable the light to be projected in an outward entire circumferential direction of the balloon. Thus, even if the light projector is used as a night-time lighting for a road work and the like, the light of the lighting instrument can be radiated in a wide range without causing a driver of a passing vehicle to feel its glaring effect.
