  "textContent": "A light-emitting diode (LED) luminaire comprising an emergency-operated portion is used to replace a luminaire operated only with alternate-current (AC) mains. The emergency-operated portion comprises a rechargeable battery with a terminal voltage, a self-diagnostic circuit, and a transceiver circuit. The LED luminaire can auto-switch from the AC mains to an emergency power or the other way around according to availability of the AC mains and whether a rechargeable battery test is initiated. The self-diagnostic circuit comprises a clock and is configured to initiate self-diagnostic tests and to auto-evaluate battery performance according to test schedules with the terminal voltage examined and test results stored. The LED luminaire further comprises a remote controller configured to initiate remote control signals with phase-shift keying (PSK) signals transmitted. The transceiver circuit is configured to demodulate such PSK signals and send commands to the self-diagnostic circuit to request responses accordingly.",
