Abstract:
A solid-state light source (SSLS) structure with integrated control. In one embodiment, a SSLS control circuit can be integrated with a SSLS structure formed from a multiple of SSLSs. The SSLS control circuit controls the total operating current of the SSLS structure to within a predetermined total operating current limit by selectively limiting the current in individual SSLSs or in groups of SSLSs as each are turned on according to a sequential order. The SSLS control circuit limits the current in each of the individual SSLSs or groups of SSLSs as function of the saturation current of the SSLSs. In one embodiment, the individual SSLSs or groups of SSLSs has a turn on voltage corresponding to a voltage causing a preceding SSLS or group of SSLSs in the sequential order to saturate current.
