Abstract

The analysis of the illumination devices at work have been performed, methods of illumination calculation and their simplified forms have been presented. The set requirements for the lighting systems have been analyzed and the program of the lighting calculation has been investigated. Experiment on measuring the amount of illuminance on the working surface of the room has been executed and the data of experiment has been compared with the calculation results. It has been measured that the data of experiment coincides with the calculation results. Seven separate lighting systems have been examined; their efficiency of lighting the whole working surface and separate working places has been measured. The research on uniformity of illuminance on the whole working surface and separate working places has been performed. The influence of the objects that exist in the room, such as monitors, workers, on the efficiency and uniformity of illuminance in the working places has been examined. Deficiencies and advantages of separate lighting systems have been explained in the performed research. The received results are summarized in the conclusions.
