Abstract
A light source for machine vision applications includes a housing having a thermally conductive base plate which supports an array of high intensity LEDs. The LEDs are fitted with secondary lenses which are aimed such that the light beams from the LEDs illuminate fixed targets having a predetermined spatial relationship so that the light source produces a very uniform light field. After the lenses are aimed, they are secured in the desired position relative to their associated LEDs using a UV-curable adhesive.
