Choice of power and control hardware for smart LED luminary

This paper analyzes the most significant details of development of a modern luminary. One of the effective ways to improve the energy efficiency of lighting systems and luminaries is to use the so called smart luminaries. This means that the luminaries turn on exactly at the place and time when the light is required, as well as with the required intensity of light. Such approach is especially effective if LED elements are utilized. Development of the smart LED luminaries includes several tasks: elaboration of energy efficient power supply equipped with distance controllable dimming function; choice and implementation of sensors; choice and development of communications for data exchange between luminaries, sensors and overall control system. The paper briefly describes the main problems of development of the smart lighting systems with LEDs as well as their solutions.
