Application range of violet band (domain)

Time: 2018-10-16  View: 776  Author: Paul
Violet, also called UV (Ultra Violet), is the shortest wavelength of light in visible light. Some bands of violet light are often called "black light" because the light in these bands is invisible to the human eye. UV violet is Optical waves with shorter wavelengths than visible light and longer than X-rays can be distinguished by wavelengths from the perspective of human health and environmental impact:

UV Violet: Visible Light Purple (400-420nm) Usually used in lighting decoration products such as lighting

UVA (315~400nm), also known as long-wave violet or "black light". This kind of application is the widest range, up to the money detector, mosquito lamp, mosquito killer lamp, down to the nail lamp, sterilization lamp beauty equipment.

UVB (280~315nm), also known as medium wave violet.

 UVC (200~280nm), also known as short-wave violet or bactericidal violet. This kind of deep ultraviolet is also used for medical equipment and military purposes. It exposes bare skin to direct damage to the human body. The sterilization effect is strong...

 UVD: vacuum ultraviolet (100-200nm)

 The sunlight contains ultraviolet light in the three bands of UVA, UVB and UVC, but due to the absorption of the ozone layer in the air, 99% of the ultraviolet light reaching the ground is in the UVA band.

 UV violet light plays a big role in skin treatment. UV violet can be used for: psoriasis, allergies, eczema, jaundice and other skin diseases.

 Phototherapy is a clinical method of treatment with light. In different spectra, especially UV light has been used as an effective and universal light source to treat a range of diseases, including: rickets, psoriasis, allergies, Eczema, jaundice, etc. In the process of phototherapy, the skin or damaged part of the patient is irradiated with different wavelengths of violet light according to the actual situation. Most of the wavelengths are in UVA (315nm~410nm) or UVB (280nm~315nm). Scope, during use, UV light can promote the biological reaction of skin cells to inhibit the cell's excessive growth and kill T cells in the skin

 One of the benefits of UV radiation is that it stimulates the production of vitamin D. Vitamin D plays a very important role in promoting bone growth and calcium and phosphorus absorption, immune function and blood cell composition. Vitamin D is due to skin exposure to sunlight. It is produced by the reaction of purple light in the sun, especially the violet light in the UVB band, and the vitamin D in the human body can be obtained by irradiating the skin with a transaction or UV light.

In addition to the contribution of UV violet to the medical industry, UV in other wavelength ranges has different uses, such as sterilization, banknote counterfeiting, light curing, printing, industrial, military, etc.
