The ultraviolet light is very useful. It has many applications in the commercial, industrial and healthcare sectors. Ultraviolet light is a kind of electromagnetic radiation. Its wavelength is close to that of X-rays and light.The LED technology is improving and so the UV LED lights are becoming more available in the market. The UV light has higher energy compared to the visible light and so it is more useful. Here we are going to discuss the various uses of UV lamps.
Tanning and skin treatment
UV light is used for tanning. It can be used to imitate the impact of sunlight on the skin. For indoor tanning, use of UV light is very common. In fact, many people prefer indoor tanning to sun tanning. The rays of the sun are not uniform, so it may cause sunburn at times. You also need to be under the sun for a longer period of time to get the tan. The indoor tanning, on the other hand, requires only about 20 minutes. Another disadvantage of sun tanning is that the sun contains both UVA and UVB beams. The UVA beams are responsible for the tanning, but the UVB beams are harmful as it might affect your DNA. The UV lamps used in salons for indoor tanning doesn’t contain any UVB beams. So, it is safer. Ultraviolet light is effective in treating smallpox lesions. UV phototherapy is effective in treating vitiligo and psoriasis. It can also prevent the growth of certain type of skin cancer.
UV lamps can be used to inspect various materials and surfaces. Materials react in different ways when they are exposed to the UV light. Some substances absorb the UV light’s energy and change it into visible light. It is called fluorescence. For example, the ink of a highlighter pen has fluorescent dye. So, the dye glows in the dark. UV lamps can provide efficient lighting in homes and offices. These lights are used to decorate nightclubs.The UV beams emit a black light. This black light is useful in many ways. It can be used to inspect splits, breaks, and various defects. You can view certain things using the UV light that are not visible to the naked eye. So, it is also used as an analytic tool. This light is used by the detectives and other companies for inspection of documents, forged bank notes, etc.
Disinfection and germ control
The ultraviolet light can inactivate the small creatures in the water. So, it is used for disinfecting drinking water. This process is absolutely chemical free and can effectively destroy bacteria that have a wavelength of 240 to 280 nanometers. The light destroys the bacteria’s capacity to …
