Lighting device including a split lighting engine

摘要

The present invention relates to a lighting device 100, 200, 300 comprising a split lighting engine having at least two thermally separated sub-engines 104, 106, 202, 204, 206, 302. Each sub-engine includes at least one solid state light source 114, 212, 306 and components 118, 210, 304 that regulate current or power to the at least one solid state light source 114, 212, 306. Therefore, the sub-engines 104, 106, 202, 204, 206, 302 can be driven individually based on the thermal environment of each sub-engine.
