Each of the multiple ridges has a first reflecting surface, a second reflecting surface, and a ridge line which is the line of intersection of the first reflecting surface and the second reflecting surface. An imaginary line containing the ridge lines intersects the central axis (CA) at a position closer to the front side than the ridge lines."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Luminous flux control member, light-emitting device, surface light source device, and display device","description":"This luminous flux control member has: an incidence surface through which light emitted from a light-emitting element enters; an emission surface through which the light entering from the incidence su","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9683719","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.
