Abstract
Micro-channel-cooled UV curing systems and components thereof are provided. According to one embodiment, a lamp head module includes a high aspect ratio, high fill factor array of light emitting devices and a submount. The array includes multiple groups of electrically seriesed light emitting devices that are connected in electrical parallel. The submount is of monolithic construction and includes multiple L-shaped patterned circuit material layers. Each of the L-shaped patterned circuit material layers includes an arm portion and a stem portion. The arm portion functions as a light emitting device bond pad and the stem portion functions as a wire bond pad and a circuit trace. Each light emitting device of a group is affixed to a corresponding arm portion of the submount. The stem portions are located external to the array, run parallel to the length of the array and perform a primary current carrying function for current flow between adjacent light emitting devices of the group.
