THE DAYLIGHT EFFECT ON THE VARIATION OF ARTIFICIAL LIGHTING BASED ON LED TECHNOLOGY
Abstract
Daylight controls our natural biorhythm, influences our mood, has an important effect on how we feel and has an essential role in creating a healthy workplace. In most cases, daylight is not enough for reach the levels of illumination appropriate to the normal operation and we use artificial light. Incorrect lighting affects people's comfort, can lead to physical fatigue (especially eye fatigue) and reduced intellectual performance, especially when high concentration is needed. The implementation of lighting systems based on LED technology in the seminar halls, using the natural light input via a light sensor, provides lighting flexibility and ensures a level of illumination appropriate to the our activities. By replacing the current lighting systems with the LED technology and implementing a lighting control system there are significant reductions in energy consumption and CO2 releases. The OccuSwitch DALI protocol is a sensor that connects to the luminaires to be controlled. The sensor has two functions: a light sensor and a motion sensor for presence control. By implementing this solution, savings of up to 70% can be achieved compared to the current lighting system.
