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.

Abstract: Apparatus for curing a substance. The apparatus includes a diode for emitting electromagnetic energy at a frequency selected to cure the substance and a culminator positioned to receive at least a portion of the electromagnet energy emitted by the diode. The culminator is selected to concentrate and intensify the received energy and to direct the energy toward an area of the substance. The area has a length and a width less than the length.

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 occurs in an inert atmosphere. In one embodiment, a printed circuit is disposed in the base portion to provide power to the LEDs.
