More specifically, the invention provides a light-emitting device and a method of temperature compensation using a light-emitting device, wherein the light-emitting device includes a substrate, a first LED chip which is arranged on the substrate, and which has a characteristic such that Δx and Δy, each representing an amount of displacement on an xy chromaticity diagram, both are negative as temperature rises, and a second LED chip which is arranged on the substrate, and which has a characteristic such that Δx and Δy, each representing an amount of displacement on an xy chromaticity diagram, both are positive as temperature rises."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light-emitting device and method for compensating chromaticity of light-emitting device","description":"An object of the present invention is to provide a light-emitting device having a temperature compensation function implemented with simple circuitry, and a method of temperature compensation in such ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9702515","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.
