Wireless Luminaires

Abstract

The development in the field of lighting technology is focused on new technologies, light sources with higher efficiency and better lighttechnical parameters and the development of luminaires, especially in the field of design and small light sources. The efficiency of light sources is associated with converting of electricity into the light in the entire process chain, including the efficiency of power wires and ballast systems. It can be stated that the losses in the power supply line and wires path are less important in comparison with the actual process of internal energy conversion in light sources. Since the beginning of use of electrical energy for the conversion to light the conductor and wires are used. The luminaires are fixed to one place and move with them is limited to a small place. The solution may be a wireless power and energy transfer. The result of this solution is the possibility of placing the luminaires anywhere in a defined space without wires and cables. The disadvantage is significantly lower efficiency of energy transfer and strong electromagnetic interference, which may exceed the limits of EMC and affect the operational of other electrical equipments. Questionable issue is the exposure of human body to RF fields unnecessarily. This paper deals with the search for potentially useful applications of wireless powering in lighting.
