Dual-Mode Dimming of a Light

An article of manufacture comprising a non-transitory storage medium having instructions stored thereon that, if executed, result in:

• controlling at least one control line based on a brightness value, wherein the at least one control line is capable to control a brightness of a light emitting device;
• receiving a message over a network;
• changing the brightness value based on the message;
• and
• changing the brightness value based on information regarding a modulation of a power input.

An integrated circuit comprising:

• at least one control line output capable to control a brightness of a light emitting device;
• at least one memory location to store a brightness value;
• at least one input to receive information regarding a modulation of a power line;
• and
• supervisory circuitry coupled to the at least one control line output, the at least one memory location, and the at least one input;
• wherein the supervisory circuitry is configured to:
• receive a message over a network;
• change the brightness value based on the message;
• change the brightness value based on the information received from the at least one input;
• and
• control the at least one control line output based on the brightness value.

A lighting apparatus comprising:

• at least one light emitting device;
• detection circuitry coupled to a power input of the lighting apparatus and arranged to detect a characteristic of a modulation of the power input;
• and
• a networked controller, coupled to the detection circuitry, configured to control a brightness of the at least one light emitting device based on a brightness value, and to change the brightness value based on the characteristic of the modulation of the power input and one or more messages received over a network.
