The controller carries out a first control process in which the discharge lamp driver is so controlled that an absolute magnitude of the drive current in a first period is smaller than that in a second period and that an AC current is supplied to the discharge lamp in a second period. The first control process includes a first electric power control process in which first average drive electric power is determined based on the voltage detected by the voltage detector and a current is supplied to the discharge lamp in such a way that average drive electric power is set at the first average drive electric power."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector","description":"A projector includes a discharge lamp, a discharge lamp driver that supplies the discharge lamp with a current, a voltage detector that detects a drive voltage for driving the discharge lamp, and a co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8506092","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.
