With the spread of COVID-19, UV disinfection is gradually being used in everyday life. So what is UV light? Is it harmful to the human body? Will it really disinfect completely?

Let’s dive right in now, and you can click on the question that interest you, 

1. Classification of UV light

The uses of ultraviolet light include a wide range of applications in commercial, industrial, and healthcare environments. Ultraviolet light (UV light) is divided into three basic categories based on the nanometer or wavelength of ultraviolet emission: UVA, UVB, and UVC. UVC light is the shortest wavelength emitted by the sun, and most of it is absorbed by the ozone layer.

  • UVA light between 315 and 400 nm
  • UVB light between 280 and 315 nm
  • UVC light between 100 and 280 nm

UV technology allows lighting engineers to replicate UVC radiation, thereby providing efficient disinfection properties. Ultraviolet lamps provide germicidal effects and many other purposes in many applications and are used in a wide range of industries worldwide. Some of the most common uses of ultraviolet light include:

Lighting-Of course, the original purpose of the lamp is to illuminate. UV lamps provide energy-saving and bright light for many industries, such as manufacturing, clean room production, quality inspection, and many other applications that require a good lighting environment.

Luminous signs-Luminous signs are needed for many purposes, such as illuminating emergency exits in public places and marketing and brand awareness. LightSources and our important partner Voltarc provide fluorescent and neon lighting solutions and have decades of experience in custom design solutions.

Backlight-Ultraviolet lamps provide backlight for avionics and aerospace industries and provide reliable lighting for cabins and cockpits. LightSources and our key partners provide experienced backlighting solutions that include high-quality UV lamps designed specifically for backlighting in many demanding industries, including the NASA space shuttle.

UV curing-Used in many manufacturing applications, UV lamps used to cure inks, coatings, and finishes provide enhanced uses for UV coatings. Adhesives, varnishes, and varnishes cured with UV lamps are more durable and long-lasting in demanding environments such as industrial, automotive, and aerospace applications.

Tanning-Ultraviolet light is the core technology of the tanning salon, providing customers with a way to enjoy the sun-kissed look brought by man-made technology. LightSources has introduced proprietary technology designed to improve tanning performance and safety, which has brought many benefits to the tanning industry.

Phototherapy-UV lamps provide many medical benefits for many diseases, such as skin diseases, including other diseases such as acne, jaundice, psoriasis, eczema, and seasonal depression.

Sterilization-UVC germicidal lamps are designed to replicate UVC radiation, which has been proven to have powerful germicidal and disinfecting properties. Today, germicidal UVC lamp applications are the first choice for many industries around the world that require water, air, or surface disinfection.

2 Sterilizing UVC lamps and applications

Various uses of UV lamps Air-UVC germicidal lamps are used in air disinfection systems, including the upper-room ultraviolet germicidal irradiation (UVGI) system, and can also be placed in the HVAC system to disinfect the air as it passes through the HVAC system. Prevent mildew and mildew on the cooling coil. The UV air disinfection system can be used almost anywhere, especially in public places such as hospitals, schools, libraries, airports, and any places where people with limited ventilation gather. Ultraviolet air disinfection is very important. Hospitals can improve the health of patients with respiratory diseases such as asthma and prevent the spread of hospital-acquired infections.

Water-UV lamps also provide a safe and effective way to treat water without the use of harmful chemicals that can pollute rivers, oceans, and other water bodies. UV lamps can be used cost-effectively for water purification in water recycling, wastewater, drinking water, industrial and commercial process water, swimming pools and spas, aquaculture, and life science applications.

Surfaces-UV surface disinfection is very effective as a valuable tool in many industries and environments. The hospital uses ultraviolet disinfection to disinfect the surgical equipment in the ward. Surface disinfection is important in restaurants and commercial kitchens, as well as in public places such as airports, bus stations, and public transportation systems. Ultraviolet light significantly improves the sterile environment of the hospital and helps prevent the spread of diseases.

Food industry-UV germicidal lamps provide many benefits for the food and catering industry. Food irradiation is an efficient and safe food processing method approved by the FDA. Food irradiation can prevent premature deterioration of various foods, extend shelf life, maintain nutritional value, and help eliminate food-borne diseases such as E. coli and Salmonella. UVC lamps can prevent viruses from accumulating on food preparation surfaces, dining areas, and restaurants. Ultraviolet germicidal lamps provide many benefits to the catering industry and can be used in water, air, and surface applications.
