  • Patent number: 9502149
    Abstract: A UV system for irradiating a substrate includes a lamphead having an enclosure with an interior. A UV bulb is positioned in the interior and is capable of emitting UV energy when excited by RF energy. The UV system also includes a solid state RF source capable of generating the RF energy. The RF energy is transmitted to the UV bulb, which causes the UV bulb to ignite and emit the UV energy from the interior of the lamphead.
    Type: Grant
    Filed: August 11, 2014
    Date of Patent: November 22, 2016
    Assignee: Nordson Corporation

  • Patent number: 6894299
    Abstract: Apparatus and method for treating a product with ultraviolet light. The apparatus includes a chamber having an inlet and an outlet, and an interior space between the inlet and the outlet. An ultraviolet light permeable conveyor is configured to move the product through the interior space from the inlet to the outlet. The conveyor has a top surface which receives the product and an opposite bottom surface. A source of ultraviolet light is coupled to the chamber and is configured to direct ultraviolet light in at least first and second portions within the interior space toward the conveyor. A first reflector is positioned in the interior space and above the top surface of the conveyor such that the first portion of the ultraviolet light is redirected toward the product on the top surface.
