What is the role of the purple light? The disinfection principle of purple light
The purple lamp is actually an ultraviolet lamp. The ultraviolet lamp is a device that emits ultraviolet rays. Generally, this kind of lamp will not be used in life without special circumstances. The main thing in life is for disinfection, but it is not only that. , What is the role of the purple light? Secondly, what is the disinfection principle of the purple light? Don't worry, BENWEI LIGHTING is here to explain it to everyone, let's take a look.
Purple light
What is the role of the purple light?
1. Ultraviolet disinfection, purple light can emit ultraviolet light, long-term exposure can cause serious damage to human eyes and skin. Violet light tube will damage the eyes for about 5 minutes. When it is necessary to use ultraviolet light for disinfection, the operator must wear protective equipment, such as the use of multi-functional protective glasses to protect the eyes, must not be directly exposed; at the same time, avoid skin contact with ultraviolet radiation. When performing ultraviolet disinfection in public places, irrelevant personnel should be avoided, especially to prevent the elderly and children from entering the ultraviolet lamp work area by mistake.
2. Ultraviolet medical treatment. Ultraviolet light is not necessarily harmful to the human body. Some wavelengths of ultraviolet light can also remove the patient’s pain in clinical practice, such as vitiligo. After the drug is applied, it can be irradiated with some ultraviolet rays to produce melanin. The effect of treatment.
3. Ultraviolet detection. In terms of anti-counterfeiting, people shape special patterns with ultraviolet fluorescent materials. Under normal light conditions, there is no image displayed, but under ultraviolet light, this fluorescent pattern can be seen. Mainly used in passports, train tickets, medical packaging, bottle caps, currency verification, etc.
4. Ultraviolet sterilization. This method is effective. Ultra-strong ultraviolet rays can instantly kill viruses in the water. It is mainly used for disinfection in hospitals, public places, kindergartens, nursing homes and other spaces. This method is slowly entering the daily life of the family. ; Water treatment and so on.
5. Ultraviolet curing, ultraviolet glue, ultraviolet ink, etc. will instantly change from liquid to solid under ultraviolet light to achieve the effects of fixing and coloring. The carbon-sulfur analyzer is one of the most closely related to our daily lives, even more common than sterilization, but this process is unknown to most people. Modern optoelectronic products are involved. For example, there are many applications on mobile phones, such as LCD sealing, the bonding of the voice coil and the sound film on the earpiece, the spraying of the phone shell, etc., the laser head in the optical drive, the computer LCD, the hard disk head , There are the latest optical communication devices, ultraviolet printers and so on.
6. Ultraviolet background light. Some substances are more clear under ultraviolet light than visible light. This feature can detect some substances that are not easy to find under normal circumstances, such as dust detection in factory purification rooms, product surface cleanliness inspection, Public security investigation and extraction of fingerprints and so on.
Purple light
The disinfection principle of the purple light:
Ultraviolet rays are a kind of low-energy electromagnetic waves, which are widely used in medical, sanitation and epidemic prevention, food industry, pharmaceutical industry and other sectors because of their good sterilization effect. However, how to use the ultraviolet lamp correctly to ensure its sterilization effect, extend the service life of the lamp tube, and avoid accidental injury, requires every operator to master it first. Now I will talk about the experience of using it in the past few years.
1 The principle of ultraviolet disinfection
Using ultraviolet radiation, the bacterial protein is photolyzed and denatured, and the amino acids, nucleic acids and enzymes of the bacterial body are destroyed and died. At the same time, when ultraviolet rays pass through the air, the oxygen in the air is ionized to produce ozone, which strengthens the sterilization effect.
2Ultraviolet disinfection method
Ultraviolet rays are mostly used for disinfection of air and surface of objects, with a wavelength of 2573A. It is used for air disinfection, the effective distance does not exceed Zm, the irradiation time is 30-60min, and it is used for disinfection of items. In order to ionize the oxygen in the air to produce ozone).
3 UV disinfection measures
3.1 Because we all use ultraviolet radiation for air disinfection, we must first ensure that the lamp is intact and used correctly, and at the same time, the lamp must be monitored regularly. The intensity of the ultraviolet lamp is less than 70uwc/lining should be replaced in time . The lamp should be kept clean. The surface of the lamp tube should be lightly tested with an alcohol cotton ball every 1 to 2 weeks to remove dust and grease, so as to reduce the factors that affect the penetration of ultraviolet rays.
3.2 The lamp should be handled with care. Turning on the lamp immediately after turning off the lamp will reduce the lamp life. It should be cooled for 3 to 4 minutes and then turned on. It can be used continuously for 4 hours, but ventilation and heat dissipation should be good to maintain the life of the lamp.
3.3 The treatment room should be kept clean and dry at all times, and the treatment room should be wiped with a special cloth soaked in disinfectant every day. Mop the floor with a special mop.
3.4 Regulate the daily monitoring and registration items of ultraviolet lamps. It must be registered in separate rooms and lamps. The registration book includes the lamp activation date, daily disinfection time, cumulative time, performer's signature, and intensity monitoring registration. It is required to record carefully after disinfection, so that The execution is consistent with the record.
3.5 Use an ultraviolet intensity indicator card or an intensity monitor to measure the intensity of the lamp first to ensure that the intensity of the new lamp is 100. Above w/c lining. After replacing the new lamp, the use time of the mold meter starts to count again. After the cumulative use time of the lamp reaches 1000h, contact the professional staff of hospital infection monitoring in time to monitor the lamp's radiation intensity. If it is qualified, continue to use it, and if it fails, replace it in time. Lamp tube to ensure the disinfection effect of the ultraviolet lamp.

3.6 When air disinfection, open all cabinet doors, drawers, etc. In order to ensure that all spaces in the treatment room are fully exposed, they are all irradiated by ultraviolet rays, and there are no dead corners in the disinfection as much as possible.
3.7 Strengthen the management and supervision of some outpatient clinics, laboratories and other departments. It is recommended to install ultraviolet light timer switches in the outpatient department, which can prevent the waste of power and the effective life of the lamps due to negligence in work and forget to turn off the lights.
3.8 Staff should make work arrangements before ultraviolet disinfection to avoid walking in the room during the disinfection process, which will affect the disinfection effect and receive unnecessary exposure; when the monitoring nurse monitors the intensity of the lamp, due to the large number of lamps, the You must wear protective goggles and protective clothing during monitoring; in wards where ultraviolet lamps are installed, the switch of the ultraviolet lamp must be separated from other ordinary lamps or be marked, and the patient and family members must be explained to the patient and family members not to turn on the ultraviolet light at will Lights, so as not to cause undesirable consequences.
What is the role of the purple light and the explanation of the knowledge of the principle of disinfection of the purple light will stop here. The content is for your reference only, and I hope it can be helpful to everyone.
