Abstract
A light source and method for operating a light source are disclosed. The present invention includes a light source and method for using the same. The light source includes a power coupler, a reconfigurable two-dimensional LED array and a controller. The power coupler is configured to receive a power potential that varies as a function of time. The LED array has a plurality of configurations of LEDs, each configuration being characterized by a minimum bias potential and a maximum bias potential. The LED array generates light when a potential between first and second power terminals is greater than the minimum bias potential. The controller varies the configuration of the array such that the power potential remains between the minimum and maximum bias potentials as the power potential varies.
