Some Studies on Content of Ultraviolet Rays in Conventional Light Sources vs LED

Anubrata Mondal, Biswajit Gayen, Suvro Mallik, Himadri Banik


The abstract Light is a type of electromagnetic radiation that primarily emits visible, ultraviolet (UV), and infrared (IR) waves. Which is known as optical radiations. The Ultra Violet radiations in this spectrum, which are generically classed as UV-A, UV-B, and UV-C. It's true that UV[1]-shorter C's wavelength has more harmful effects than UV-A while UV-impact B's is more moderate. Whether artificial or natural, light is used to create visual perception. Electric lamps that have been very useful in artificial lighting can be divided into three categories: filament lamps (although their use is waning), gas discharge lamps, and solid-state LED lamp assemblies. As a result, UV[2] radiation levels in people must be evaluated when artificial lighting is used. Studies have been done in laboratories on numerous lamps that are frequently used. It has been noticed that the lamps' UV content varies. The UV concentration typically tends to decline with distance. The analysis of test results, including the UV content of various lamps and the effects of various categories of UV wavelengths, is covered in this study.
