Patent ID: 7170100

Claim:
A system comprising: a substrate; an array of light emitting devices supported by the substrate, the array having an outer perimeter that defines an area, the array of light emitting devices being positioned such that a ratio of a sum of a total area of all of the light emitting devices in the array of light emitting devices to the area defined by the outer perimeter is at least about 0.75; and a package containing the substrate and the array of light emitting devices, the package having a layer configured so that at least about 75% of the light that emerges from the light emitting devices and impinges on the layer passes through the layer, wherein the layer is disposed such that a distance between a surface of the array of light emitting devices and a surface of the layer nearest to the surface of the array of light emitting devices is from about five microns to about 400 microns.
