Beschreibung
Zusammenfassung:	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.
