Abstract
A lighting apparatus includes an isolation transformer, an output rectification and voltage regulation circuit, an output current limiting and filtering circuit, and a signal detection and generation circuit. The homonymous terminal of the primary side opposes the homonymous terminal of the secondary side. The output rectification and voltage regulation circuit is connected to the secondary coil of the isolation transformer. The output rectification and voltage regulation circuit rectifies and stabilizes the voltage signal output by the isolation transformer. The output current limiting and filtering circuit is connected to the dimmer and the output rectification and voltage regulation circuit. The output current limiting and filtering circuit adjusts the output current and output voltage according to the operation of the dimmer, and the output current limiting and filtering circuit limits and filters the signal output by the output rectification and voltage regulation circuit.
