A UV LED device may be used for curing fluids. In one embodiment, LEDs are positioned on faces defined by an inverted recess in a base portion. The LEDs are configured such that the light beams emitted from the LEDs converge at a single area or point to provide a single, focused area or point of amplified power from the LEDs. In another embodiment, the base portion is elongated to provide a single, focused line or region of amplified power from the LEDs. In another embodiment, the curing process...
