The surface layer includes a high refractive index region with a refractive index nhigh and a low refractive index region with a refractive index nlow. nbase and nsurface satisfy the equation |nsurface−nbase≥0.001, nhigh is greater than or equal to nbase 1, and nlow is less than nbase. The high refractive index region is optically coupled to the base layer such that at least a portion of light propagating through the base layer leaks out of the base layer and into the high refractive index region. A display device or a luminaire can include the lighting unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting unit with laminate structure","description":"A lighting unit includes a glass laminate structure including a base layer formed from a first glass composition with a refractive index nbase and a surface layer fused to a surface of the base layer ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11506938","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.
