What is the structure of the UV-curable lamp? What are the materials that make up the components of the UV curing lamp? In the ultraviolet light generated by the mercury discharge tube in the UV curing lamp: an inert gas of mercury vapor, a quartz tube containing two electrodes and an insulator.


At the highest point reached at 254 nm, 310 nm and 366 nm in mercury, radiation between 200 and 400 nm is produced. Quartz cuts a shorter wavelength and does not deliver radiation below 230 nm.


Each atom consists of a nucleus with many electrons floating around it in a fixed orbit. By adding energy (electrical) electrons are brought in a higher orbit.


Each element shows a trend back to its original state. The electron will retreat in its previous orbit: Excessive energy is emitted as a photon.


The ultraviolet lamp used in normal times is made by pressing a dielectric mercury arc lamp or an MPMA lamp. It can be produced in lengths from a few millimeters to over 2 meters. The life of these lamps varies from 1000 to 2500 hours.


The tube is made of quartz, because this material can not only transmit ultraviolet light but also tolerate a material with a high temperature of 6 to 800 °C. If the lamp is damaged, it will easily reach the melting point (1100 ° C)


The electrodes are made of tungsten: the process of producing them is extremely complicated. Tungsten is used because the temperature of the curve can rise above 3,000 °C.


A molybdenum plate is used to connect the electrodes and wires, which can be expanded together with quartz. And still can withstand high voltage when heated.


The lamp is finally suspended to a ceramic (or other) insulator.


Because the supply current is often not enough to power a MPMA lamp, the UV lamp typically uses a transformer. Two types will be used: induction and repair of power transformers. Standard ballasts are also used up to 5 kW capacity.
