The lighting device 3 is switched on at the time τ. Duration τ pulse generator 7 is determined by the required duration of the illumination of one of the lighting unit, and the repetition period of pulses T is the number of consecutively included lamps 2. In the second lamp 2 delay the moment of switching on of the lighting device 3 is 2 τin the third - 3 τ and so on. In other respects the operation of the lamps 2 are similar. This series connection of lamps 2 can create, for example, the effect of the traveling wave in the direction to exit from the premises. If necessary, create different lighting effects, the ratio of the time delay and duty cycle of the lamps may be different.
