Abstract
An ultraviolet (UV) light-emitting diode (LED) device for curing fluids such as inks, coatings, and adhesives, for example. 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. An optical culmination device may be used to further intensify the power output from the LEDs. The optical culmination device provides enhanced power output from the UV LED device which makes the curing process more efficient than previous curing systems.
