Abstract
A lighting instrument includes: a substrate; a plurality of first light-emitting diodes (LEDs) disposed over the substrate, wherein the first LEDs each have a first value range for a light output characteristic; a plurality of second LEDs disposed over the substrate, wherein the second LEDs each have a second value range for the light output characteristic, the second value range being different from the first value range; a phosphor layer located at a distance above the first LEDs and the second LEDs; and a light-reflective layer that is disposed on a surface of the phosphor layer; wherein the first LEDs interleave with the second LEDs according to a predefined pattern.
