Abstract:
A light having a plurality of LEDs and a switching substrate is disclosed. The switching substrate is coupled to LEDs and includes a plurality of switches that provide a plurality of configurations for the LEDs. Each configuration is characterized by a two-dimensional array of LEDs having a minimum bias potential and a maximum bias potential, the LED array generating light when a bias potential is provided between the power terminals that is greater than the minimum bias potential, at least two configurations being operable to provide light at bias potential within this range. The switching substrate is sub-dividable into a plurality of identical multi-LED light sources by dividing the switching substrate along predetermined lines. The array of LEDs can be organized as a nested array of LEDs. The switches can be implemented as passive switches that are set by removing portions of conductors or bridging gaps in conductors.
