Abstract
A dimmer for dimming light emitted by a light source is presented. The dimmer includes a regulation switch for regulating a current flowing through the light source and a regulator circuit that provides an electronic parameter to control the regulation switch. The regulator circuit has a dimmer switch for passing or blocking the electronic parameter, and a signal generator generating a plurality of modulated signals configured to operate the regulator circuit in a first phase and in a second phase. In the first phase the regulation circuit maintains the electronic parameter to a target value. In the second phase the regulation circuit monitors a variation of the electronic parameter and maintains the electronic parameter to a predetermined value.
