In the thesis I primarily describe the theoretical background of light radiation and identification of its colours. The criteria for quality lighting are also presented and the corresponding standard SIST EN12464/1, which is applicable in engineering of new lighting in an industrial facility. I also examined the impact of artificial light on human visual abilities and its psychophysical impact on the human body. Following is an overview of existing lighting of the production hall 1 of the company Carthago d.o.o. According to the findings of irregularities of existing lighting I searched for possibilities for improvement of existing lighting. Since the existing lighting is outdated and energy inefficient, I have determined that it is pointless to invest in additional equipment, because the difference in energy efficiency would be minimal and the quality of lighting would have remained unchanged. That’s why I have made a proposal for renovating lighting with energy-efficient LED lamps. I examined the quality of light of the new lighting by work posts with the help of simulations in Dialux and calculated the energy efficiency. Finally, I performed a comparison of energy efficiency of the existing and new lighting by individual work areas and presented the findings of the comparison.
