The BF22140-24B is a cold cathode fluorescent (CCFL) lamp, composed mainly of cylinder made of quartz glass, filled with low-pressure mercury vapor with a high proportion of Ar and a very small fraction of rare gas. It is typically used as an ultraviolet (UV) source, since its emission of UV light is much higher than that of standard fluorescent or incandescent lamps.

The main application fields of the BF22140-24B are in the UV curing industry, particularly in applications that involve the rapid curing of adhesives, coatings, inks, and other materials with ultraviolet light. This lamp is also used in UV lithography, for exposure to special materials during the printing process in order to achieve a uniform layer of coatings or printing inks. Additionally, the BF22140-24B is suitable for photochemical processes and the production of special effects, like glow in the dark objects.

The working principle of the BF22140-24B is based on electrodeless UV light production. This happens when an electric field is applied across two electrodes outside the lamp, creating an alternating current in the quartz tube. This results in the ionization of the gas present inside the tube, which emits UV light when the current passes through it. Since this process is completely electric, its intensity can be easily regulated by controlling the current, allowing for precise control of the emitted UV radiation.

The BF22140-24B offers the advantages of a stable and long emission lifetime, with a total lamp life of 20,000 hours and a dual-lament technology, which reduces the risk of lamp outages even at low temperatures. This lamp also has excellent color rendering properties and a wide spectral range of UV radiation from 200nm to 450nm, allowing for multiple applications.

In conclusion, the BF22140-24B is a cold cathode fluorescent lamp used mainly for UV curing, UV lithography, photochemical processes and production of special effects. Its working principle lies in the application of an electric field across two electrodes, creating an alternating current in the quartz tube, and ionizing the gas present inside the tube, leading to UV light emission. This lamp offers the advantages of long and stable emission lifetime, excellent color rendering and wide spectral range of UV radiation.
