FIELD: lighting equipment.
SUBSTANCE: power source which controls the semiconductor light sources the signal of light reduction is stopped only during a predefined period T beginning with a time binding right after the power is fed, in order to light the diodes 26-29, in order to have a certain amount of light (for example, the minimum amount of light). After the predefined period T has elapsed, the light reduction signal is stopped to light the diodes 26-29 to have the necessary amount of light prescribed by the light reduction signal.
EFFECT: strong stable lighting.
