Abstract
A light-emitting device comprising (a) a submount having front and back sides and including a ceramic layer; (b) an array of light-emitting diodes (LEDs) on the front side; and (c) a lens overmolded on the submount and covering the LED array. In some embodiments, the submount comprises at least two electrically-conductive contact pads on the front side, and each LED in the array is secured with respect to one of the contact pads.
