The element 2 is covered with a light-reflecting filler-containing resin 5, which is prepared by causing a flexible silicone resin to contain, before being cured, light-reflecting or light-scattering fillers 5a having a particle diameter larger than the wavelength of light emitted by the element 1. This causes light emitted from the element 1 to be reflected by the resin 5, instead of being absorbed by the element 2, so that such light is released to the outside of the light-emitting device 70. This allows the device 70 to extract light to the outside with high efficiency, and also allows for easy formation of the resin 5 having a desired pattern and position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light-emitting device","description":"To provide a light emitting device easy to produce and extracting light to its outside with high efficiency, the light-emitting device 70 of the present invention includes an insulating base 10; a lig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8476657","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.
