The light emitting element of this light emitting device has a junction temperature of from 100° C. to 200° C. at the time of continuous driving. Furthermore, the phosphor layer contains a phosphor represented by the following general formula (A), which absorbs the light emitted from the light emitting element and thereby emits light having a main emission peak in the wavelength region of equal to or greater than 650 nm and equal to or less than 665 nm:(Mg1-x,AEx)a(Ge1-y,Sny)bOcHAd:zMn  (A)wherein AE represents at least one or more elements selected from the group consisting of Ca or Sr;"},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light emitting device","description":"There is provided a light emitting device which includes a light emitting element having a main emission peak in the wavelength region of greater than 420 nm and equal to or less than 500 nm, and a ph","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471458","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.
