Abstract:
1. A solid state light source module comprising: at least two solid state light sources for generating at least two corresponding lights of different colors, each light containing at least one primary color component; a light combining device for combining the at least two lights into a combined light containing at least two primary color components; an output device for alternatingly outputting the at least two primary color components of the combined light to generate an output light having a predefined color sequence which repeats every period; a sync signal generator coupled to the output device for generating a periodic sync signal; and a controller coupled to the sync signal generator and to each of the at least two solid state light sources, for supplying a drive signal to each of the at least two solid state light sources based on the sync signal, wherein during at least one sub-period of the period, one of the at least two solid state light sources is turned on by its drive signal and another one of the at least two solid state light sources is kept in an inactive state by its drive signal.
