Abstract: Hermetically sealed, hygienic electrical enclosures that do not require mechanical fasteners and methods of making the same. In some examples, an open housing is sealed with a cover using a seal that includes an arrangement of a gasket and a sealant. Once cured, the seal provides a hermetic seal between the housing and cover, providing a crevice-free device enclosure.

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: A forced air cooling unit for a light source formed of an array of high intensity light emitting diodes (LEDs). A housing includes side walls with a pair of grooves on the inside of the walls. A heat sink includes side extensions which are slidably received in the grooves. The LED array is mounted in thermal contact with the heat sink so as to protrude from the top of the housing. The housing side walls include a second pair of inside grooves below the first pair. The second pair of grooves slidably receive a cooling fan base plate. An internal air flow chamber thus defined by the housing side walls, the base plate and the heat sink. A cooling fan, mounted at one end of the base plate, draws cooling air into internal chamber. The air flows by the heat sink, carrying with it heat generated by the LEDs, to the other opposite end of the base plate, where it exits the internal chamber through openings in the base plate.
