Dual-mode dimming of a light
First Claim
1. Circuitry comprising an input line, and an output line;
- the circuitry configured to;
receive a message over a network;
receive information regarding a characteristic of a power line through the input line, the information being different than the message and indicating a value of the characteristic that is between maximum and minimum expected values; and
control the output line based on both the message and the information regarding the characteristic of the power line.

Abstract
A lighting system includes a master lighting device, a control unit, and one or more slave lighting devices. The master lighting device includes a power input, a light emitting component, a memory device, a processor, and a network interface to communicate over a network. The memory device stores computer readable code that when executed by the processor, causes the master lighting device to receive a message that includes brightness information over the network, receive information regarding a characteristic of power received at the power input, control a brightness level of the light emitting component based on the brightness information and the information regarding the characteristic of the power, and send a message to the slave lighting devices to control their brightness level. The control unit includes a network interface send the message that includes the brightness information over the network.

17. A lighting apparatus comprising:
-
means for receiving a brightness message over a network at the lighting apparatus; means for detecting a change in a characteristic of a power input of the lighting apparatus, the change being less than a difference between maximum and minimum expected values of the characteristic of the input power; and means for changing a brightness of the lighting apparatus based on both the brightness message and the change in the characteristic. - View Dependent Claims (18, 19, 20)
