Abstract
LED chips comprising pluralities of active regions on the same submount are provided. These active regions are individually addressable, such that beams output from the LEDs can be controlled simply by selectively activating the desired active region in the plurality without requiring advanced optics and reflectors comprising complex moving parts. In some embodiments, one or more active regions can surround one or more other active regions. In some embodiments, the various active regions are individually addressable by virtue of each active region comprising its own anode and sharing a common cathode. In some embodiments, the various active regions are individually addressable by virtue of each active region comprising its own cathode and sharing a common anode. In some embodiments, each active region comprises its own anode and its own cathode.
