Abstract: A medical diagnostic instrument, such as a colposcope for examining cervical tissue, includes a light source comprising an annular array of high intensity light emitting diodes (LEDs). The LED array includes a central access opening which provides viewing access for the colposcope optical components to the illumination site. The array includes a plurality of sets of LEDs, with each set including a red, blue and green emitting LED. The intensities of the red, blue and green LEDs, respectively, are controllable with a controller to continuously vary or tune the spectral characteristics of the illumination from the light source. Selected color mixes can be stored in a memory for later retrieval.

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.

Abstract: The present invention relates to an LED light source for a machine vision system. The light source includes a plurality of LEDs each arranged in a base plate in predetermined manner during manufacturing. Each LED is then securely mounted to the base plate with an ultravioletly curable adhesive to remain pointed in the predetermined manner. The light source also includes an optically efficient non-lambertain diffuser which receives light from each of the LEDs and breaks the light up to provide a uniform light field to illuminate an object under inspection.
