NTC-17.54.2 “Lighting. Investigation of workplace lighting conditions”

The training laboratory system provides the possibility of carrying out laboratory works in the course of “Life safety. Lighting”. 

 

A frontal panel is designed as separate fragments of electric circuits investigated in laboratory works. A diagram on the panel is a combination of the following items: different lots for investigation of linear fluorescent lamps with starter circuit switching and with electronic ballast, an anti-strobe circuit of the two fluorescent lamps, connection of external lamps through a standard electrical outlet and a key switch.

 

A lux meter-pulse meter and a photometric unit of transparent polycarbonate, which has a rotatable platform with an angular scale, are used for registration of the dependence of illuminance of the working surface on its angulation. Angulation is registered on the scale. Bulbs in the lamp on a flexible stem are replaced in order to determine brightness of the working surface with various light sources.
