NEW SGEM Scientific Online eLibrary
After a long time work, our pride is the absolutely new SGEM Online eLibrary, available here. The Library is created according the rules of the International databases, with a whole needed information and ability to export the article in BIB format. Try and spread your experience with us.
Till we complete the new library with papers from all the years, you can use this link /Full Old Library/, if papers that you need are not visible yet here.

THE DAYLIGHT EFFECT ON THE VARIATION OF ARTIFICIAL LIGHTING BASED ON LED TECHNOLOGY

Manolescu, A.; Husch, M.
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.
