To achieve these goals, a kind of emergency light of embedded ceiling, including box body, lamp body retainer and reflector, Lamp body retainer is connected on the pedestal of box body, and reflector and box body outer wall detachable connection, lamp body retainer are used to install LED, battery and emergency circuit being installed in box body, emergency circuit includes the current rectifying and wave filtering circuit being connected with AC power, Current rectifying and wave filtering circuit is connected with electronic inverter circuit, and electronic inverter circuit is connected with LED；Also include what is be connected with AC power Power sense circuit, and the charge and discharge control electricity being connected with power sense circuit, current rectifying and wave filtering circuit, electronic inverter circuit Road, charge-discharge control circuit are connected with battery.
Further, charge-discharge control circuit includes the transformer for being connected in parallel on 220V alternating currents both sides, and transformer both sides connect Connect rectifier, the both sides of rectifier are connected in parallel with a capacitor C1 and relay, the diode that the positive pole of relay passes through series connection T1 and resistance R1 is connected to the positive pole of battery, and the negative pole of battery is connected with the negative pole of relay, and the both sides of battery are in parallel LED lamps and relay switch.
Further, electronic inverter is using drivers such as the boost type LED worked under low-voltage and high-current state.
Further, the power sense circuit uses the high impedance signal detector of 7555 time base circuits composition.
Further, the power output of electronic inverter can carry out on-off control by selecting switch.
Further, the reflector is made in specular Louvre form.
Box body is embedded in ceiling, LED is reflected pipeline by reflector, and luminous efficiency is high, and will not produce dazzle； High-voltage ac power is converted to low-voltage dc power supply by rectifying and wave-filtering and powered for lamp source, while is charged for battery, works as appearance During the situation of power-off, the actuating of relay, battery is powered for LED, a diode of being connected on relay circuit, so as to ensure Quick acting after relay power-off.In order to extend the power-off lighting time, and luminous flux does not become caused by the fluctuating of battery tension Change, NPN transistor is added in inverter circuit and adjusts pipe as invariable power；The 7555 real base circuits used can be rapid It is inverter power supply that electric energy is called from battery by charge-discharge control circuit.Response time of the invention is fast, dazzle is small, can be with Also serve as illuminator.
