1, ultraviolet disinfection, violet light will emit ultraviolet light, long-term exposure will cause serious damage to people's eyes and skin. Violet light will hurt your eyes for about 5 minutes. When ultraviolet lamp must be used for disinfection, the operator must wear protective equipment. If you use multifunctional protective glasses to protect your eyes, you must not directly illuminate them. At the same time, skin contact with ultraviolet radiation should also be avoided. When ultraviolet disinfection is carried out in public places, irrelevant personnel should avoid it, especially to prevent the elderly and children from straying into the ultraviolet lamp work area.
2, ultraviolet medical treatment, ultraviolet rays are not necessarily harmful to the human body, and some bands of ultraviolet rays can also relieve the pain of patients in clinic, such as vitiligo. After applying medicine, receiving some ultraviolet rays can produce melanin and achieve therapeutic effects.
3, ultraviolet detection, in anti-counterfeiting, people use ultraviolet fluorescent substances to shape special patterns. Under general illumination, there is no image, but under ultraviolet irradiation, this fluorescent pattern can be seen. Mainly used for passports, train tickets, medical packaging, bottle caps, banknote inspection, etc.
4, ultraviolet sterilization, this way is very effective, ultra-strong ultraviolet rays can instantly kill viruses in water, mainly used for disinfection in hospitals, public places, kindergartens, nursing homes and other spaces, and this way is slowly entering the daily life of families; Water treatment and so on.
5, ultraviolet curing, ultraviolet glue, ultraviolet ink, etc. Under the irradiation of ultraviolet light, it instantly changes from liquid to solid, thus achieving the effect of color fixation and coloring. Carbon and sulfur analyzer is the most closely related to our daily life, even more common than sterilization, but most people don't know this process. Modern photoelectric products will be involved, such as many applications on mobile phones, LCD packaging, bonding of voice coil and sound film on earpiece, spraying of mobile phone shell, laser head in CD-ROM drive, computer LCD, hard disk head, latest optical communication devices, ultraviolet printer and so on.
6. Ultraviolet background light. Some substances are clearer under ultraviolet light than under visible light. This function can be used to detect some substances that are not easy to find in general, such as dust detection in factory clean room, product surface cleanliness inspection, public security investigation, fingerprint extraction and so on.
Purple light details:
Violet lamp (BLB), also known as ultraviolet lamp, is a device that can emit ultraviolet rays, a necessary tool to observe the fluorescence and phosphorescence characteristics of samples, and a physical means of sterilization and disinfection. The wavelength is in the range of 10~400nm.
