Abstract
A luminaire adapted to apply an auto-gradient effect across pixels has an interface coupled by a connection to a controller. The controller has electronic circuitry that receives a predetermined start light parameter for a start pixel of a luminaire and receives a predetermined end light parameter for an end pixel of the first luminaire, the predetermined end light parameter greater than the predetermined start light parameter. The controller circuitry then automatically interpolates a gradient effect for a middle light parameter of each of a plurality of middle pixels of the luminaire based on the start and end predetermined light parameters. The controller circuitry then outputs control signals having the start, end and middle light parameters to the start, end and middle light pixels, respectively, through the connection and to the interface.
