Abstract: A light projector includes a power generator 6; a bogie 1 for mounting the power generator 6; an extendable or retractable supporting column 2 vertically installed at the bogie 1; a balloon 4 arranged at an upper end of the extendable or retractable supporting column 2; and a lighting instrument 3 stored in the balloon 4, wherein the power generator 6 and the lighting instrument 3 can be electrically energized. The lighting instrument 3 is lit through supply of electricity from the power generator 6 installed at the bogie 1 and the light thus generated is changed into a soft-feeling light through the balloon 4 so as to enable the light to be projected in an outward entire circumferential direction of the balloon 4. 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.

Abstract: There is provided a light projector comprised of a power generator 6; a bogie 1 for mounting the power generator 6; an extendable or retractable supporting column 2 vertically installed at the bogie 1; a balloon 4 arranged at an upper end of the extendable or retractable supporting column 2; and a lighting instrument 3 stored in the balloon 4, wherein the power generator 6 and the lighting instrument 3 can be electrically energized. With such an arrangement as above, the lighting instrument 3 is lit through supplying of electricity from the power generator 6 installed at the bogie 1 and the light thus generated is changed into a soft-feeling light through the balloon 4 so as to enable the light to be projected in an outward entire circumferential direction of the balloon 4. Thus, even if the light projector is used as a night-time lighting for a road work and the like, light of the lighting instrument can be radiated in a wide range without causing a driver of the running vehicle to feel its glaring effect.
