Semiconductor light-emitting device

A semiconductor light-emitting device, comprising:

• a substrate including a substrate front surface, and a substrate back surface facing away from the substrate front surface;
• front-surface electrodes formed in the substrate front surface;
• back-surface electrodes formed in the substrate back surface and configured for mounting the semiconductor light-emitting device;
• a semiconductor light-emitting element including a first light emitter, a second light emitter, a first element front-surface electrode electrically connected to the first light emitter, a second element front-surface electrode electrically connected to the second light emitter, and an element back-surface electrode electrically connected to both the first light emitter and the second light emitter;
• a first drive circuit electrically connected to the first element front-surface electrode and configured to drive the first light emitter;
• and
• a second drive circuit electrically connected to the second element front-surface electrode and configured to drive the second light emitter,
• wherein the element back-surface electrode of the semiconductor light-emitting element, the first drive circuit, and the second drive circuit are mounted on the front-surface electrodes.
