Abstract
The present disclosure involves a lighting instrument. The lighting instrument includes a board or substrate, for example, a printed circuit board. The lighting instrument also includes a plurality of light-emitting devices disposed on the substrate. The light-emitting devices may be light-emitting diode (LED) dies. The LED dies belong to a plurality of different bins. The bins are categorized based on the light output performance of the LED dies. In some embodiments, the LED dies may be binned based on the wavelength or radiant flux of the light output. The LED dies are distributed on the substrate according to a predefined pattern based on their bins. In some embodiments, the LED dies are bin-mixed in an interleaving manner.
