Abstract
Emergency lighting with a charging indicator circuitry comprises a power source module, a lighting circuit, a battery circuit, and an emergency switch circuit. The battery circuit includes charging indicator circuitry and a battery module; the power source module is connected with the battery module via the charging indicator circuitry. When the utility power is interrupted or a test switch is pressed, the light of the charging indicator circuitry goes out to indicate that the emergency lighting is in discharging status. When the utility power is supplied normally, if a battery within the battery module is in disconnected state, the light of the indicating circuitry goes out to indicate that the emergency lighting is in disconnected state. The charging indicator circuitry may be a simple light-emitting indicating circuit, has no need for much modification to the original circuit during manufacture and design, and may be simple and quickly-responsive.
