A connector is electrically connectable to an external power source device and includes a first terminal for supplying electric power from the external power source device to a main capacitor and a second terminal for discriminating a type of the external power source device. An obtaining unit obtains the information for discriminating the type of the external power source device by comparing a voltage value of a signal input to the second terminal from the external power source device with a predetermined voltage threshold when an attribute of the second terminal is set to an input. A discrimination unit discriminates the type of the external power source device by contrasting the information obtained with information stored."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device, lighting system, and external power source device","description":"A lighting device that is capable of discriminating a type of an external power source device connected from among types of connectable devices without increasing the number of terminals of a connecto","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9807853","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.
