Dual-mode dimming of a light
First Claim
1. A method for controlling brightness of a lighting apparatus, the method comprising:
- receiving a message over a network at the lighting apparatus, and changing a brightness of the lighting apparatus based on the message; and
detecting a change in a characteristic of a modulation of a power input of the lighting apparatus, and changing the brightness of the lighting apparatus based on the change in the characteristic.

Abstract
A lighting apparatus includes at least one light emitting device, such as one or more LEDs, detection circuitry coupled to a power input of the lighting apparatus and arranged to detect a characteristic of a modulation of the power input, supervisory circuitry, such as a processor, coupled to the detection circuitry, and a network interface, coupled to the supervisory circuitry, to communicate over a network. The supervisory circuitry is adapted to receive a message that includes brightness information over the network, receive information regarding the characteristic of the modulation of the power input from the detection circuitry, and control a brightness of the at least one light emitting device based on the brightness information and the information regarding the characteristic modulation of the power input.
