The first and second polarizing reflective plates have a specific length and width, and a back surface formed from a high reflectance plate. The light source is secured to the reflective hood. A specific interval is provided between the first and second polarizing reflective plates and the reflecting surface of the reflective hood, and a specific interval is provided between the two plates with the optical axis passing through the 0° direction angle of the light source in between."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light source device and illumination device using the same","description":"A light source device is provided with an LED having strong directivity, a reflective hood which has an interior reflecting surface for reflecting the illumination light from the light source, and a p","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8500308","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.
