Abstract
A lighting device includes: a first input terminal for receiving an AC voltage phase-controlled by a first phase-control dimmer; a first light source unit which emits light of a first color; a second light source unit which emits light of a second color different from the first color; a control circuit which controls a total amount of light emitted from the first and second light source units and the color of combined light including the light emitted from the first and second light source units. The control signal includes first and second control information. The first control information is for controlling either one of the total amount of light and the color of combined light, and corresponds to the conduction angle of the first phase-control dimmer. The second control information is for controlling the other of the total amount of light and the color of combined light.
