Abstract:
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.
