Abstract

The paper is focused on designing a smart LED power supply, with adjustable working point in accordance with local conditions, LED photometric characteristics. We have develop a flyback driver controlled by a signal which is a combination of the sensed LED forward current, and a PWM working regime. This method is used in order to increase the LED lighting efficiency at the same thermal regime. At the end of the implementation we have tested major issues related to the correct work of the LED, energetic and luminous efficiency, and the way of sensor integration into the smart system.
