    摘要: A device includes a light source, a sensor, and a controller. The light source includes at least one light emitting device connected to a mount. The light emitting device comprises a plurality of segments with neighboring segments spaced less than 200 microns apart. In some embodiments, the plurality of segments are grown on a single growth substrate. Each segment includes a III-nitride light emitting layer disposed between an n-type region and a p-type region. The mount is configured such that at least two segments may be independently activated. The controller is coupled between the sensor and the mount. The controller is operable to receive an input from the sensor and based on the input, selectively illuminate at least one segment in the light source.
