Until now, the basic design of an LED lamp has remained fundamentally unchanged. The common formula has been to use a single, high power GaN chip (or a few larger chips), add phosphor (remotely or directly), and drive the chip(s) with as much power as possible to yield the maximum amount of white light. The key to the longevity of the lamps is to effectively dissipate the heat that is generated by the large LED chips. This is why so many LED lamps have large heat sinks added to the base of the lamps.
