Abstract
A lighting apparatus includes a first light source, a second light source, a current controller, a current source and a signal converter. The light source set has a first light source and a second light source. The current source is controlled by the current controller for generating a first driving current to the first light source and for generating a second driving current to the second light source. The signal converter for converting a first type control signal to a second type control signal. The first type control signal indicates a light parameter to be produced by the light source set and the second light source. The second type control signal includes a clock signal and a data signal supplied to the current controller to determine the first driving current and the second driving current.
