The feeding system applied in electric system of lighting of eletrodomu00c9stico refrigeration

摘要

The feeding system applied in electric system of lighting of eletrodomu00c9stico cooling this invention refers to a system of electrical supply, especially capable of maintaining the value of the voltage effectively responsible for the electrical supply of the system of lights In existing in a refrigeration appliance capable of being electrically powered by at least two tracks NOMInais of electrical voltage input. For both, the system has at least one component of illumination (3) electrically powered by electric voltage substantially constant whose value is based on only one of the tracks the nominal electrical voltage from the entry of the electrical network (2).Preferably, the generation of electrical voltage level substantially constant based on the effective control of the angle of firing of the electrical voltage from the entrance of the electrical network (2), and more specifically, to control the angle of firing of the electrical voltage from the entrance of the power grid ICA (2) is carried out by means of at least one thyristor.
