Abstract

A switched light element array includes first, second and third light emitting elements, and first and second switches. The first light emitting element includes first and second terminals, and the second light emitting element includes a first terminal, and a second terminal coupled to the second terminal of the first light emitting element. The third light emitting element includes a first terminal coupled to the first terminal of the first light emitting element and a second terminal. The first switch includes a first terminal coupled to each of the first terminals of the first and third light emitting elements and a second terminal coupled to the first terminal of the second light emitting element. The second switch includes a first terminal coupled to the second terminal of the third light emitting element, and a second terminal coupled to each of the second terminals of the first and second light emitting elements.
