The LED driving circuit may be configured to operate normally only with the AC mains providing a regulated power and a current to LED arrays. When an input AC voltage is applied to the LED lamp, the at least six diodes and the at least two frequency sensitive devices can detect the input AC voltage, control electric current flowing into the switch control module or the LED driving circuit, and complete current returns so that the LED lamp can operate with either the ballast or the AC mains without operational ambiguity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state lighting operable with ballasts and line voltages without ambiguity","description":"A light-emitting diode (LED) lamp using an LED driving circuit, at least two frequency sensitive devices, at least six diodes configured to convert an AC voltage into a DC voltage and manage electric ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9844123","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.
