Hybrid LED driver device

Abstract

The invention relates to lighting technology and is aimed at improving hybrid LED drivers and can be used in the production of LED lighting lamps. A hybrid LED driver device includes: a diode bridge; a choke connected in series to it; at least two LED assemblies connected in series to the choke; at least two transistors, one of which is connected to the anode of the first LED assembly, and characterized in that it includes at least one diode connected by its anode to the anode of the second LED assembly, and by its cathode to the second transistor. A distinctive feature of the proposed technical solution is the inclusion of a protective diode in series with the control transistor, which eliminates hard switching of the hybrid driver semiconductors. This results in increased efficiency and reduced heat dissipation in the protective diodes.
