Abstract
The lighting apparatus includes a driver circuit and a lighting system. The driver circuit includes a signal receiver module, a signal processing module and a signal execution module. The signal receiver module is configured to receive a parameter signal of a coding device. The signal processing module is connected to the signal receiver module. The signal processing module is configured to convert the parameter signal into a PWM signal. The signal execution module is connected to the signal processing module. The signal execution module is also configured to convert an alternating current input power source into a direct current power source. The direct current power source is filtered based on the PWM signal. In this way, the filtered direct current power source matches a required power source of the lighting apparatus. The lighting apparatus solves low inapplicability and compatibility that occurs in the driver circuit of the convention art.
