Abstract
A light source includes a substrate; an array of un-packaged light emitting semiconductor devices (LESDs), each of the LESDs having at least one surface for emitting light and a substrate surface being attached to the substrate; and a plurality of electrical connections, each electrical connection coupled for providing electrical power to a respective LESD. The LESDs are arranged on the substrate with sufficient density and light generating capability to provide a predetermined irradiation from the light source.
