Abstract
An illumination source is made from number of light emitting diodes (LEDs) which are distributed on a substrate that is formed into a generally concave reflector surface. The substrate may initially be a sheet with a hub-and-spokes form that is subsequently reshaped to define the reflector surface. In some cases a plenum defined between the substrate and a housing is used to allow a coolant to circulate past the substrate.
