FIELD: physics.
SUBSTANCE: switched array of light elements has first, second and third light-emitting elements and first and second switches. The first light-emitting element has first and second leads, and the second light-emitting element has a first lead and a second lead connected to the second lead of the first light-emitting element. The third light-emitting element has a first lead connected to the first lead of the first light-emitting element, and a second lead. The first switch has a first lead connected to the first leads of the first and third light-emitting elements, and a second lad connected to the first lead of the second light-emitting element. The second switch has a first lead connected to the second lead of the third light-emitting element, and a second lead connected to the second leads of the first and second light-emitting elements.
EFFECT: fewer circuit components.
