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 reproduce. So, no more bacteria grows in the water. UV light is widely used in water treatment facilities. This method of treating water is a lot more efficient than boiling water. The UV light can also get rid of chlorine and chloramine from water. Another use of the UV lamp is that it used in killing germs that are found in equipment, utensils, worktops, etc. This technique of germ control is used in the commercial businesses as well. It helps to avoid cross contamination or food poisoning. The UV light can also be used to increase the shelf life of vegetables and fruits.
Air Cleaning and bug eradication
Mold growth inside the house can affect the indoor air quality. If you can install UV air purification unit in your air conditioner duct then the quality of air can be improved. The UV-C light, which is in the 280 to 100 nm range, is used for air purification. This UV light can kill mold, mildew, germs, viruses, and bacteria that float in the air. You can use an air purifier that has the UV-C light technology. In this type of air filter, air passes through a HEPA filter. Then it passes through a small chamber and gets exposed to the UV-C light. Sometimes, the air goes through another filter before getting inside the room. You should use 36-watt bulbs for this purpose. UV lamps are used for killing bugs in the house as well. It is used in the modern bug zappers and has proved to be very effective in killing bugs. The UV-A light, in the range 380 to 315 nm, attracts many bugs and insects like houseflies, wasps, mosquitoes, etc. Unlike the humans, these insects can actually see the ultraviolet light. When the bug zapper is on, the insects get attracted to UV light and go towards the mesh. They become electrocuted once they come into contact with the electric grids and gets vaporized. The bug zapper is a very popular means of killing bugs and insects today.
UV lights are used in the production of polyphenols. It is a very beneficial plant and is said to prevent cancer. It can also make you look young. It can help in raisin production as well. It can also help in the production of medical cannabis. In fact, the UV light helps in improving the medicinal properties of cannabis.
The UV light is found in the sunlight. It has a shorter wavelength than the natural light. Due to research and innovation, the UV lamp can now be used in a number of different ways that are beneficial to people. It can help users in our daily lives. It has many commercial and industrial applications as well. It is used for treating water, purifying air, tanning, treating skin diseases, indoor gardening, eradicating bugs, identifying things, etc. In future, the scientists will be able to come up with more uses of UV lamps.
