Patent ID: 8035313

Claim:
A light element array, comprising: a first light emitting element having a first terminal and a second terminal, the first light emitting element characterized by a first operating voltage (Vop 1 ) at or above which the first light emitting element is substantially operable to emit light; a second light emitting element having a first terminal, and a second terminal coupled to the second terminal of the first light emitting element, the second light emitting element characterized by a second operating voltage (Vop 2 ) at or above which the second light emitting element is substantially operable to emit light; a third light emitting element having a first terminal coupled to the first terminal of the first light element, and a second terminal, the third light emitting element characterized by a third operating voltage (Vop 3 ) at or above which the third light emitting element is substantially operable to emit light; a first current source coupled between the first terminal of the first light emitting element and the first terminal of the second light emitting element; and a second current source coupled between the second terminal of the first light emitting element and the second terminal of the third light emitting element.
