A first light source illuminates a first region. A second light source is configured to provide lower luminance than that of the first light source. The second light source illuminates a second region that overlaps the first region, and that has a larger area than that of the first region. A lighting circuit drives the first light source and the second light source according to a common lighting instruction. The lighting circuit gradually turns on the first light source and the second light source with different gradual changing time periods in response to the lighting instruction.

Devices, systems, and methods for modifying an existing electrical circuit to enable a conventional mechanical switch to integrate with and operate smart devices, while also providing continuous power supply and cooperating with external operation of the smart devices (e.g., via a mobile device application, smart controller, etc.). The smart device thus is operable both via the physical switch and via a home automation system, without loss of power to the smart device computer and transmitter components caused by use of the wall switch. This may be done via a replacement switch or faceplate which effectively bypasses the physical switch to ensure continuous power to the smart device while also inferring and transmitting the toggle state of the switch by measuring an amount of current through the faceplate.

An intelligent electrical switch comprising a conventional mechanical switch connected to a computer system in communication with an external device and receiving instructions therefrom. The switch may be installed in an existing circuit to replace one switch in a multi-way wiring geometry, and includes a sensor detecting current on the neutral line. By determining the circuit state, the switch can determine whether, when instructions are received wirelessly to power the circuit on or off, the mechanical switch element should be toggled.
