Abstract: A multi-chip light emitting device (LED) uses a low-cost carrier structure that facilitates the use of substrates that are optimized to support the devices that require a substrate. Depending upon the type of LED elements used, some of the LED elements may be mounted on the carrier structure, rather than on the more expensive ceramic substrate. In like manner, other devices, such as sensors and control elements, may be mounted on the carrier structure as well. Because the carrier and substrate structures are formed independent of the encapsulation and other after-formation processes, these structures can be tested prior to encapsulation, thereby avoiding the cost of these processes being applied to inoperative structures.
