Abstract

A sub-assembly (100) matable to a waveguide (210) having a recess (220) therein includes a structure comprising a discrete light source (150) disposed on a carrier (110), and a substrate (120) and a heat spreader (130) disposed beneath the structure The structure has a contour complementary to the recess, such that, when the sub-assembly is joined to the waveguide, the discrete light source is within the waveguide A sub-assembly is further disclosed which includes a discrete light source, wherein substantially all of the light emitted therefrom is emitted from a top surface; and a reflective carrier disposed beneath and in direct contact with the discrete light source, a top surface of the reflective carrier comprising an inner diffusive region (500) surrounding the discrete light source and a specular region (510) surrounding the inner diffusive region.
