Abstract

Experimentally there has been established the influence of different ways of regulating the luminous flux (regulated laboratory autotransformer and triac regulator industrial manufacturing of «VIKO» 600W/1000W ROTATIVE DIMMER) of thermal and low-pressure discharge lamps (with different colors and colors temperature) on a coefficient of luminous flux pulsations. It has been supplemented by scientific data a concept of spatial pulsations of the luminous flux, which arise in the premises when using the two-four lamp luminaries with split phase. This made it possible to formulate the requirements for their rational location in the premises. Experimentally there has been established: a) the coefficient of luminous flux pulsations of thermal light sources by regulating laboratory autotransformer decreases and by triac regulator - increases; b) any of these ways of regulating the luminous flux of linear and compact fluorescent lamps in the network of industrial frequency of 50 Hz, leads to an increase in of the coefficient of luminous flux pulsations, regardless of the configuration (linear or shaped compact fluorescent lamp), the color temperature and the color of fluorescent lamps. Exceptions were only for yellow fluorescent lamps in which the coefficient of luminous flux pulsations in the regulatory process is decreased. Greatest growth (1.75 times) of the coefficient of luminous flux pulsations in the process of regulation inherent the red fluorescent lamps. The smallest increased (1.35 times) inherent to blue fluorescent lamps. In colored fluorescent lamps the coefficient pulsations of luminous flux pulsations is increased in the direction of green, red,  yellow, blue, in which it is 3.78 times greater than in the green.
