Illumination system of a cooking appliance

An illumination system of a cooking appliance having a burner and a knob associated with the burner that rotates between an OFF position and a NON-OFF position, the OFF position corresponding to the burner being off, the NON-OFF position corresponding to the burner being on, the illumination system comprising;

• an electric circuit associated with the knob, the electrical circuit comprising:
• a first connection through which a supply voltage is fed to the electric circuit;
• a second connection coupled to a reference point;
• a first electrical branch that is electrically disposed between the first and second connections, the first electrical branch including activation means that is operably coupled to the knob and configured to alter a voltage drop in the first electrical branch when the knob transitions from the OFF position to the NON-OFF position;
• a second electrical branch that is electrically disposed between the first and second connections, the second electrical branch including a display device and being electrically connected in parallel to the first electrical branch, the display device being configured to illuminate when an electric current having a value equal to or greater than a minimum value circulates through the display device;
• a control module that is configured to monitored the voltage drop in the first electrical branch and to control an electric current circulating through the display device depending on the monitored voltage drop.
