NTC-17.54.3 “Lighting. Lighting engineering”

Br0.00

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

Category: Occupational health and safety

A frontal panel is designed as separate fragments of electric circuits investigated in laboratory works.

The circuit shown at the panel is realized as the sections for studying the operation of the linear fluorescent lamp with connection circuit including electronic control gear and the linear LED lamp combined at one figure. Connection of the external luminaires is made via a standard socket and a key switch. The laboratory auto-transformer is the power source for the whole circuit, and all the sections are powered up from it via measurement system.

The measuring system digitally displays the following parameters:

voltage;
current;
active power;
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.

Two linear single-lamp luminaires with a fluorescent lamp and a LED lamp are located in the chamber above; the luminaire at flexible gooseneck with E27 socket is located at the bottom. At the side wall are mounted a holder for the arc mercury tungsten lamp type and a lamp with halogen bulb.

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.

The stand is accompanied with a set of teaching materials and technical documentation intended for the teaching staff.
