Abstract
Techniques, systems and devices are described for controlling the adjustment of colors and optical power of output light of solid-state lighting devices for improved lighting performance. In one aspect, a solid-state lighting system includes a lighting device and a control panel, the lighting device including solid-state light emitters, driver circuits, line sensing electronics that receives signal modulation on a power line connecting the lighting device, a digital controller that decodes the signal modulation into a digital command, and a memory that stores the decoded digital command. The control panel sends the digital command to the lighting device via the power line and modulates electrical power to produce the signal modulation that carries the digital command. In some implementations, a visual indicator may be generated when the control panel receives a digital command from a user to acknowledge the receipt of the digital command.
