UV is (VioletRay Ultra) 200nm-450nm, UV, A:320-390nm UV C:280nm UV B:280-320nm UV, V:390nm V above

The UV lamp is a gas discharge lamp, gas discharge lamp is divided into arc discharge and glow discharge. UV curing of commonly used UV lamp to arc discharge lamp, its working principle is: in a vacuum quartz tube by adding a quantitative high pure mercury (mercury) by the electrodes at both ends of the provides a voltage difference (drop), ion discharge, resulting in ultraviolet radiation.
