Calculating power consumption of the light source includes measuring a voltage applied to both terminals of the light source, measuring current flowing to the light source, and calculating power consumption of the light source by multiplication of the measured voltage and current. Adjusting the current flowing to the light source includes calculating a difference between the preset power value and the calculated power consumption of the light source, adding/subtracting the calculated difference value to/from a preset current value to output a resultant value, and changing the voltage output to the light source according to the resultant output value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for controlling power consumption of light source in mobile projector","description":"A method of controlling the power consumption of a light source in a mobile projector, including calculating power consumption of the light source, and comparing the calculated power consumption with ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8502476","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.
