Abstract
A lighting apparatus includes a first light source, a second light source, a current controller, a current source and a signal converter. The first light source and the second light source are two light sources of a light source set. The light source set may further include more light source of same type of different type. 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 converts 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 is supplied to the current controller to determine the first driving current and the second driving current.
