Abstract: Described herein are LED chips comprising pluralities of active regions on the same submount. These active regions are individually addressable, such that beam output from the LEDs can be controlled simply by selectively activating the desired active region in the plurality without resorting to incorporation of 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.

Abstract translation: 这里描述的是包括在同一基座上的多个活性区域的LED芯片。 这些有源区域是可单独寻址的，使得可以简单地通过选择性地激活多个所需有源区域来控制来自LED的光束输出，而无需采用先进光学器件和包括复杂运动部件的反射器的并入。 在一些实施例中，一个或多个有源区域可以围绕一个或多个其它活性区域。 在一些实施例中，各种有源区域可通过包括其自身阳极的每个有源区域和共享公共阴极而单独寻址。 在一些实施例中，各种有源区域可通过包括其自己的阴极的每个有源区域共享共用阳极来单独寻址。 在一些实施例中，每个有源区域包括其自身的阳极及其自身的阴极。
