Abstract

This article deals with the problems associated with the management of the power output of the luminous flux of LED lamps that have in its composition uncontrollable driver configured in accordance with single-stage circuitry. Based on the analysis of typical schemes of this class drivers for implementation of management functions in it chip PWM type controller L6562 from STMicroelecronics has been chosen. Next feedback circuit at the output current of LEDs has been investigated and the reference voltage circuit presented in the article scheme ofc circuit diagram on the basis of the controller whereby reconfigured reference voltage circuit, and values denomination electronic components corresponding circuits for implementing the driver functions dimming have been calculated. As a result of practical implementation of the circuit based on the above derived parameters refinement LED lamps that meet the requirements for their operation, thus resulting in failure of the second-stage used in construction standard of dimmable driver, the construction has been significantly simplified and the cost reduced.
