Abstract
A lighting system includes a main power source, a power switch, a daylight white color light source driver, an incandescent color light source driver, a first light source unit, and a second light source unit. The power switch includes a first terminal connected to the main power source, a second terminal and a control terminal. The two drivers are connected to the second terminal of the power switch. The first light source unit is driven by the daylight white color light source driver. The second light source unit is driven by the incandescent color light source driver. A switch driving circuit for applying power-saving switch signals is connected to the control terminal of the power switch, and a signal processing circuit for outputting instruction signals is connected to the switch driving circuit.
