Cold Cathode Fluorescent (CCFL) & UV Lamps

Cold Cathode Fluorescent Lamps (CCFLs) and UV lights are specialized light sources that utilize a mercury vapor to emit ultraviolet (UV) light, which then causes a phosphor coating to produce visible light in the case of CCFLs. UV lights, on the other hand, provide wavelengths within the ultraviolet frequency range. CCFLs and UV lights are available in various sizes to suit different applications. The width of these lights typically ranges from 2.0 mm to 11 mm, while their length can vary from 25 mm to 600 mm. This range in size allows for flexibility in designing lighting systems that cater to specific requirements. CCFLs use a cold cathode technology, where the mercury vapor inside the lamp is excited by an electric field generated between two electrodes. This excitation causes the mercury vapor to emit UV light. The phosphor coating present on the inner surface of the lamp then absorbs this UV light and re-emits it as visible light, providing illumination. CCFLs find application in various devices such as LCD monitors, backlit displays, and scanners. UV lights, on the other hand, emit light within the ultraviolet frequency range without the additional step of converting it into visible light. These lights are designed to emit specific UV wavelengths required for various applications, including sterilization, photochemical processes, forensic analysis, and medical treatments. The size range of CCFLs and UV lights allows for their integration into different systems and equipment, depending on the specific lighting requirements. They are commonly used in various industries, including electronics, healthcare, manufacturing, and scientific research. In summary, Cold Cathode Fluorescent Lamps (CCFLs) and UV lights are specialized light sources that utilize mercury vapor to emit UV light and visible light (in the case of CCFLs). They come in a range of sizes, from 2.0 mm to 11 mm wide and 25 mm to 600 mm long, allowing for versatility in lighting system design. CCFLs employ a phosphor coating to convert UV light into visible light, while UV lights emit light within the ultraviolet frequency range for specific applications. These lights find applications in a wide range of industries and devices.
