The semiconductor light-emitting device can include a substrate, a frame located on the substrate, the chip mounted on the substrate, a transparent material layer located on the wavelength converting layer so as to reduce from the wavelength converting layer toward a light-emitting surface thereof, and a reflective material layer disposed at least between the frame and both side surfaces of the wavelength converting layer and the transparent material layer. The semiconductor light-emitting device can be configured to improve light-emitting efficiency and a color variation by using the surrounding portion and an inclined side surface of transparent material layer, and therefore can emit various colored lights including white light having a high light-emitting efficiency from a small light-emitting surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor light-emitting device","description":"A semiconductor light-emitting device can include a wavelength converting layer including a surrounding portion, which covers at least one semiconductor light-emitting chip in order to emit various co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9793455","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.
