The combination of light from the first and second emitters generates an emission color point within a standard deviation of the BBL. A second group of solid state emitters is included, the combination of light from the first and second groups of emitters causes emission within a standard deviation of the black body locus (BBL), wherein varying the intensity of the second group of emitters causes emission from the first and second groups of emitters to vary within a range of color temperatures while still emitting within the standard deviation of the BBL."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High CRI adjustable color temperature lighting devices","description":"Solid state luminaires and light engines comprising a first group of solid state emitters comprising a first emitter emitting above the black body locus (BBL) in a CIE diagram, and a second emitter em","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8511851","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
