Description

(1) Technical field: [0001] The invention relates to the technical field of control of electric light sources, and is a digital intelligent power supply for electromagnetic induction lamps specially for providing power for electromagnetic induction lamps. (two) background technology: [0002] As a new type of contemporary high-efficiency and energy-saving electric light source, electromagnetic induction lamp has been widely used because of its remarkable advantages such as high luminous efficiency, good color rendering, long life, energy saving and high efficiency, and environmental protection. The electromagnetic induction lamp adopts the principle of electromagnetic induction to couple the plasma with the magnetic field lines of the circuit, and convert the external electric energy into the energy required for the internal work of the lamp. A pair of soft magnetic rings placed outside the lamp tube act like the primary coil of a transformer, and the closed lamp tube acts l...
