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, connection of external lamps through a standard electrical outlet and a key switch. The whole circuit with all elements is powered from a laboratory transformer through a measuring system. The measuring system digitally displays the following parameters: voltage, current, active power and shift angle between current and voltage.
The circuit required for a specific laboratory work is assembled by switching the individual elements of the investigated device and the measuring instruments with use of jumpers within the area of the stand which refers to the investigated circuit.
A fluorescent lamp with two linear lamps is placed in the upper part of the chamber, a lamp on the flexible stem with a holder E27 is placed in the lower part of it. A holder for a mercury arc lamp, a lamp with halogen lamp and a fluorescent lamp are installed on the side wall.
In order to determine the light distribution curve, a circular protractor is used. Lux meter – pulse meter sensor is placed in the clamp on the protractor’s flexible arm. The required arm position is set manually according to the scale and its readings are registered.
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. Lux meter – pulse meter sensor is placed in the clamp on the rotatable platform. Angulation is registered on the scale.
The values of brightness for the working surfaces of different colours are determined with use of lux meter. A set of coloured cardboard is used as working surfaces. Bulbs in the lamp on a flexible stem are replaced in order to determine brightness of the working surface with various light sources.
