Light element array with controllable current sources and method of operation

An optical element array 100 has been described, the first, second, and third light emitting elements, and a first and a second current source. The first light emitting element, comprising a first and a second terminal, characterized by a first operating voltage VOpi operable to emit light at substantially higher. A second light emitting element, comprising a first terminal and a second terminal coupled to the second terminal of the first light emitting element, the second light emitting element, characterized in operable second operating voltage Vop2 to substantially emit light in more than It shall be. A third light-emitting element, comprising a first terminal and a second terminal coupled to a first terminal of the first light emitting element, the third light emitting element, characterized in operative third operating voltage Vop3 to substantially emit light in more than It shall be. The first current source is coupled between the first light emitting element between the first terminal and the second the first terminal of the light emitting element, between the second current source and the second terminal of the first light-emitting element, the third second terminal of the light emitting element It is connected.A light emitting element, the light element array, the current source transistor, a light emitting diode, the operating voltage
