  • Publication number: 20140138550
    Abstract: An “intelligent” UV curing assembly is disclosed. The “intelligent” assembly permits automated monitoring of performance parameters, part lifetime, and inventory control of internal parts. The “intelligent” assembly includes an on lamp microprocessor. The on lamp microprocessor may be configured to recognize the internal parts, record accumulated working time of each part, and sample and process data from the plurality of “intelligent” sensors.

  • Publication number: 20130187063
    Abstract: Micro-channel-cooled UV curing systems and components thereof are provided. According to one embodiment, a lamp head module includes an optical macro-reflector, an array of LEDs and a micro-channel cooler assembly. The array is positioned within the reflector and has a high fill factor and a high aspect ratio. The array provides a high irradiance output beam pattern having a peak irradiance of greater than 25 W/cm2 at a work piece surface at least 1 mm away from an outer surface of a window of the reflector. The micro-channel cooler assembly maintains a substantially isothermal state among p-n junctions of the LEDs at less than or equal to 80° Celsius. The micro-channel cooler assembly also provides a common anode substrate for the array. A thermally efficient electrical connection is formed between the array and the common anode substrate by mounting the array to the micro-channel cooler assembly.

  • Patent number: 8357878
    Abstract: An ultraviolet (UV) LED-based lamp for UV curing lamp assemblies is disclosed. An array of UV emitting LEDs are packaged together and arranged along the length of a cylindrical lens to form a UV LED-based optical component assembly. The UV LED-based optical component assembly may be made to be modular. A UV LED lamp assembly may comprise a plurality of UV LED-based optical component assemblies arranged around a workpiece tube. The workpiece tube may be filled with an inert gas and may be made of quartz or glass. One or more curved back reflectors may be placed opposite the LED UV LED-based optical component assemblies to collect UV light escaping the workpiece tube and refocus the light to the other side of the workpiece. The UV LEDs may be arranged on a single surface or a multi-level tiered platform.
