The LED driving circuit is configured to provide a regulated power and current to drive the LED arrays. With a cycle-by-cycle triac switching and current control, an over-rated surge current is limited, preventing any fire hazards possibly occurred in the ballast when operated with the LED lamp. With various electrical connection terminals, the lamp can fit and operate in various lamp fixtures comprising two-pin, four-pin, or Edison-base sockets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state lighting without operational uncertainty and free of fire hazard","description":"A light-emitting diode (LED)-based solid-state lamp (LED lamp) comprising four input ports, two bridge rectifiers, two interface modules, an LED driving circuit, and LED arrays operates normally for a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9801241","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.
