Abstract
A light emitting diode device (e.g., LED package) may include 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. A LED device may include a first LED die and at least one additional LED die disposed at different positions within a common reflector cup or relative to a common lens. 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.
