Lighting System Efficiency in the Industrial Plants

Abstract

The article presents the most important elements of a lighting installation of the existing industrial building, how to choose from the various optimization solutions and efficient power consumption for the facility using advanced equipment control and the proper use of them in order to reduce the time of using of the artificial lighting. Energy efficiency is one of the important issues concerning lighting system control. A very significant part of building consumed energy is the lighting systems consume. Providing lighting only in the areas and in the periods lighting is needed and providing the right level of lighting as needed are effective means of reducing the energy use of the lighting system. The main control action for this purpose are on/off switching and dimming using a central control system BMS. There are presented and simulated some efficiency solutions of the lighting system within an industrial production plant that currently uses fluorescent lighting T8. The main conclusion of this article is that replacing conventional lighting systems in the industrial sector with modern lighting systems using LED technology controlled by a centralized automated intelligent BMS type, leads to increased energy efficiency. The article shows that in certain moments of time when natural light enters the building from exterior spaces through the walls or ceiling glass by automatically adjusting light intensity of lighting or just by switching some of the lamps off via light sensors and an integrated BMS system can achieve a saving of electricity consumption of approx. 30 %. By replacing lamps using T8 fluorescent tubes with new LED based lighting electricity, consumption can be reduced to approx. 60 %, and if additionally use a lighting management system centralized BMS type, saving power consumption can reach up to approx. 70 %.
