Abstract
A semiconductor light-emitting device includes a plurality of light-emitting elements disposed on a single substrate. Each light-emitting element includes a plurality of light-emitting regions that can be driven independent of each other to emit light. The largest spacing between light-emitting regions of each light-emitting element is selected such that light emitted from any of the light-emitting regions of that element can impinge on the same light-responsive element associated with that light-emitting element.
