Abstract:
In one embodiment, a single light emitting diode lamp package includes at least two light emitting devices that can be switched independently of one another and thus may be useful in vehicular lighting applications, for example low and high beam headlights. In another embodiment, a LED device includes a first LED die and at least one additional LED die disposed at different positions within a common reflector cup. Multiple LED sub-assemblies may be mounted to a common lead frame along non-coincident principal axes. Methods for varying intensity or color from multi-LED lamps are further provided.
