Integrated lamp with automatic emergency light and regular light

摘要

An integrated lamp with automatic emergency light and regular light is provided in the present invention. The integrated lamp with automatic emergency light and regular light is coupled to an AC power source, wherein the AC power source includes a first AC terminal and a second AC terminal. The integrated lamp is controlled by a lamp switch, where the lamp switch includes a first terminal and a second terminal, where an indication light circuit is coupled between the first terminal and the second terminal of the lamp switch. The integrated lamp includes an AC detector. The AC detector is coupled between the second terminal of the lamp switch and the second AC terminal. When the lamp switch is turned off, the AC detector determines whether the current state is a power failure state or a normal state according to the electrical current and/or voltage from the indication light circuit to the second AC terminal.

1. An integrated lamp with automatic emergency light and regular light, coupled to an alternate current (AC) power source, wherein the AC power source comprises
a first AC terminal and a second AC terminal, wherein the integrated lamp with automatic emergency light and regular light is controlled by a lamp switch, wherein the lamp switch comprises a first terminal, a second terminal and an indication light circuit, wherein the first terminal of the lamp switch is coupled to the first AC terminal, wherein the indication light circuit is coupled between the first terminal of the lamp switch and the second terminal of the lamp switch, wherein an indication light of the indication light circuit is lit for representing that the lamp switch is turned off when the lamp switch is turned off by an user; wherein the integrated lamp with automatic emergency light and regular light comprises: an AC detector, coupled between the second terminal of the lamp switch and the second AC terminal, wherein the AC detector detects a voltage/current status between the second terminal of the lamp switch and the second AC terminal through the indication light circuit to determine whether a present state is a power failure state or a normal state when the lamp switch is turned off; a battery, disposed in the integrated lamp with automatic emergency light and regular light, for providing an electrical power to the integrated lamp with automatic emergency light and regular light in power failure; and a lamp circuit, comprising a first input terminal and a second input terminal, wherein the first input terminal of the lamp circuit is coupled to the second terminal of the lamp switch, and the second input terminal of the lamp circuit is coupled to the second AC terminal; wherein the lamp circuit turns a lamp of the lamp circuit on by using a received AC power when the lamp switch is turned on, wherein the lamp circuit turns the lamp of the lamp circuit off when the lamp switch is turned off and the AC detector determines that the present state is the normal state, wherein the lamp circuit turns the lamp of the lamp circuit on by using the electrical power of the battery when the lamp switch is turned off and the AC detector determines that the present state is the power failure state, wherein the AC detector determines that the present state is the normal state when the AC detector detects that an AC current/voltage goes to the indication light circuit and the lamp switch is turned off, and wherein the AC detector determines that tile present state is the power failure state when the AC detector does not detect that the AC current/voltage goes to the indication light circuit.
