Abstract:
1. A light emitting device comprising: a) a plurality of LED chips operable to generate light having a dominant wavelength in a first wavelength range; and b) a package for housing the LED chips, wherein the package comprises: c) a thermally conductive substrate on which the LED chips are mounted in thermal communication; d) a cover having a plurality of through-holes in which each hole corresponds to a respective one of the LED chips and wherein the holes are configured such that when the cover is mounted to the substrate each hole in conjunction with the substrate defines a recess in which a respective LED chip is housed, e) a mixture of at least one phosphor material and a light transmissive material within the through-holes such that the cover and the mixture form a substantially planar surface; wherein the at least one phosphor material is configured to absorb at least a portion of said light and to emit light having a dominant wavelength in a second wavelength range; and f) a plurality of lenses each physically mounted on a respective one of the plurality of through-holes; wherein the plurality of lenses are one of pre-fabricated individually and pre-fabricated as an array.
