The light source image of the light source at the irradiated surface of the microlens array is elliptical, and the long axis direction of the light source image intersects with both the two directions. A coordinate system includes: a first axis that is parallel to a principal ray of the laser light incident on the microlens array; and a second axis, in a direction in which the laser light emitted from the microlens array or the fluorescence emitted from the phosphor is reflected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light source device, projector and light intensity distribution uniformization method","description":"A light source device for generating excitation light that is irradiated to a phosphor includes: a plurality of light sources that emits laser light; and a microlens array that includes a plurality of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11940719","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.
