The emergency lighting and power system is intended to automatically supply illumination or power or both in an event of failure of normal power supply. The LED driving circuit is configured to convert a terminal voltage from the rechargeable battery into an AC voltage to operate a luminaire when a line voltage from AC mains is unavailable. The charging and discharging control circuit comprises at least two relay switches configured to sense a loss of normal power supply, to switch between normal power and an emergency power to operate the luminaire in proper situations, and to meet regulatory requirements without operational ambiguity and safety issues."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state lighting with an emergency power system","description":"An emergency lighting and power system comprises a rechargeable battery, an LED driving circuit, and a charging and discharging control circuit.
