Dual junction led with non-overlapping segmentation

A method for providing illumination, the method comprising:

• emitting first light from a first junction of a dual junction light-emitting diode (LED) array from a plurality of first light-emitting areas that extend in a plane and are separated by first boundaries;
• passing the first light through a second junction of the dual-junction LED array;
• and
• emitting second light from the second junction from a plurality of second light-emitting areas that correspond in a one-to-one correspondence to the plurality of first light-emitting areas, the plurality of second light-emitting areas being separated by second boundaries that are offset in the plane from the first boundaries.

An illumination system, comprising:

• a dual junction light-emitting diode (LED) array including a first junction and a second junction that extend in a plane,
• the first junction configured to emit first light from a plurality of first light-emitting areas,
• the first light-emitting areas being separated by first boundaries,
• the second junction disposed on the first junction such that the first light passes through the second junction,
• the second junction configured to emit second light from a plurality of second light-emitting areas,
• the plurality of second light-emitting areas corresponding in a one-to-one correspondence to the plurality of first light-emitting areas,
• each first light-emitting area being configured to emit first light that passes through at least part of the corresponding second light-emitting area,
• each first light-emitting area being electrically connected in series to the corresponding second light-emitting area, such that the first light-emitting area is configured to produce the first light and the corresponding second light-emitting area is configured to produce the second light simultaneously in response to an applied current,
• the second light-emitting areas being separated by second boundaries that correspond in a one-to-one correspondence to the first boundaries,
• the second boundaries being offset in the plane from the corresponding first boundaries;
• a lens configured to direct the first light and the second light toward a scene as illumination;
• and
• a camera configured to collect illumination that is reflected from the scene to form an image of the scene.
