Methods and apparatus relating to link power savings with state retention are described. In one embodiment, one or more components of two agents coupled via a serial link are turned off during idle periods while retaining link state in each agent. Other embodiments are also disclosed.

Link power savings with state retention

A system includes a light fixture for installation at a location that is configured to be programmed to operate according to a control program. A communication interface is used for communication with the controller. An optical receiver of the fixture is configured for receiving an optical signal. The controller monitors provisioning commands received by the fixture and determines receipt of the provisioning commands in order to monitor inputs to the optical receiver and detect an optical selection signal for selecting the fixture. Upon detecting an optical selection signal the fixture processes commissioning commands. The controller, upon determining that the provisioning commands have not been received, further configured for ignoring inputs to the optical receiver so the fixture cannot be selected and programmed with commissioning commands.

System for commissioning elements in an installation

A light fixture includes an array of light-emitting elements for generating light from the light fixture, and the array of light-emitting elements includes a defined sub-array of light-emitting elements. An alternate array of light-emitting elements is coupled in parallel with the defined sub-array of alternate light-emitting elements of the light emitter. Each of the sub-array and the alternate array are coupled with a respective switch element. A control circuit is coupled with the switch elements and configured for selectively switching power between the sub-array and the alternate array for modulating the operation of the sub-array and alternate array of light-emitting elements to generate modulated communication signals.
