Abstract
Light emitting diode (LED) devices, systems, and methods for targeted beam shaping are provided. In some aspects, LED devices and methods include providing a submount and a light emission area disposed over the submount. The light emission area includes a plurality of LED chips mounted over the submount. At least some of the LED chips are provided in a first non-circular shape, such that upon illumination of the LED chips, a resultant beam pattern of light on the surface is substantially the same as the first shape. LED systems and methods include providing LEDs arranged according to a specific shape, intensity pattern, or a color pattern. Upon illumination of the LED chips, a shape, intensity pattern, or color pattern of light emitted by the system substantially corresponds to the shape, intensity pattern, or color pattern of the light emission area.
