The paper deals with current and light regulators for luminaries with Light Emitting Diodes. Several topologies of the regulators with typical control formula (buck, boost and buck-boost) and several control methods (pulse-width and frequency modulation) are analyzed from the point of view of their control performance. Special attention is paid to the non-linearity of the proposed solutions and their accuracy in practically available control platforms. The control solutions are analyzed analytically and through simulations as well as confirmed experimentally. The conclusions about the most prospective solution are made.
