Abstract

The invention concerns the direction indicator light with a mirror reflecting surface of a rotary shape, around whose top at least two compact one-cap fluorescent lamps are mounted and their longitudinal axes form an angle α of 5 to 10 degrees with the optical axis of the mirror reflecting surface, while the tops of the inner tubes of the compact fluorescent lamps either are in mutual contact or they are spaced from the optical axis by the margin that equals maximally 30 percent of the diameter of the inner tube of the compact one-cap fluorescent lamp. According to the solution, the direction indicator light can be used to advantage especially for stage and decorative lighting and also wherever directing of the light flux into a certain space angle is required, possibly wherever lighting containing minimal temperature radiation component is required.<IMAGE>
