Abstract

The automatic lighting system contains a lighting device, a control module controlling the lighting device, and a light switch through which the control module is connected to an in-house wiring in a series connection. The control module contains a power unit connecting the in-house wiring, a switch detection unit connecting the in-house wiring and the power unit, a control unit connecting the power unit and the switch detection unit, an activation unit connecting the power unit and the control unit, and a control switch connecting the in-house wiring and the control unit. The automatic lighting system provides an ordinary lighting mode functioning like an ordinary lamp and an automatic lighting mode which is triggered by ambient brightness, object movement, and preset schedule. A conventional automatic lighting could be directly replaced by a light device of the present invention without altering any existing wiring and switch configuration.

Claims

1. An automatic lighting system, comprising:

a lighting device;

a control module controlling said lighting device; and

a light switch through which said control module is connected to an in-house wiring in a series connection;

wherein said control module contains a power unit connecting said in-house wiring, a switch detection unit connecting said in-house wiring and said power unit, a control unit connecting said power unit and said switch detection unit, an activation unit connecting said power unit and said control unit, and a control switch connecting said in-house wiring and said control unit.

2. The automatic lighting system according to claim 1, wherein said switch detection unit contains a timing element capable of determining an interval time from the last state change of said light switch.

3. The automatic lighting system according to claim 1, wherein activation unit is one of a light-sensing activation unit, a motion-detection activation unit, and a time-based activation unit.

4. The automatic lighting system according to claim 1, wherein said light switch is a push button.
