About Us‎ > ‎  About UV LED Curing  UV LED Curing is a recently
developed technology designed to improve the speed, performance,
and capabilities of a wide variety of curing applications. Below
is a short introduction to UV LED curing. For a more complete
list, see the Resources section in the sidebar.   A light-
emitting-diode (LED) is a semiconductor diode that emits light
when an electric current is applied in the forward direction of
the device, as in the simple LED circuit. The effect is a form
of electroluminescence where incoherent and narrow-spectrum
light is emitted from the p-n junction in a solid state
material. An LED is usually a small area (less than 1mm -2mm)
light source, often with optics added directly on top of the
chip to shape its radiation pattern and assist in reflection.
The color of the emitted light depends on the composition and
condition of the semiconducting material used, and can be
Infrared, visible or Ultraviolet.  The first known report of a
light emitting solid state diode was
