Abstract
Multi-chip sources and related methods are disclosed. A single multi-chip lamp source can include a substrate and at least three light emitting diode (LED) chips operably configured to the substrate to form a single LED package. The LED chips can include at least three different colored LED chips. The LED chips can be configured to be actuatable either individually or together to provide selectable colored light beams. The LED chips can be positioned on the substrate such that an emitted light beam remains concentric without shifting regardless of the chip or chips emitting the light beam.
