why we should use UVC disinfection sterilizing light

As the global pandemic of Covid-19 continues, it causes unprecedented disruption to most of the businesses, particularly to hospitality and tourism. As the estimation from economic experts and medical experts of mainstream, it will take much longer time for businesses and markets to recover.

For a long time people will have a uncertainty mentally in some extent and even get fear associated with international travel and it will be of high importance for businesses to adopt further measures to instill confidence and regain customers' safey.

UV-C① radiation is a well-known disinfectant for air, water and surfaces which helps mitigate the risk of acquiring an infection and has been used extensively for over 40 years. All bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection. In laboratory testing, our UV-C light sources inactivated 99% of SARS-CoV-2 virus (causing Covid-19 disease) on a surface with an exposure time of 6 seconds3. A clear indication that UV-C light can play a valuable part in your protection strategy.

Therefore, our desktop UV-C disinfection lamp is a simple, efficient, economical and environmental-friendly way to create safe and clean environment for all people like guests,staff, teachers, students, chefs, waiters, healthcare professionals, patients and etc.Our certified UV-C disinfection lamps offer effective, safe and environmentally friendly with almost 360-degree all-aspect germicidal to bacteria, virus, mites and smell. UV sterilization has been widely adopted by hospitals and laboratories for many years and our high-quality, durable UVC lamps are now available for commercial applications, including hotels, resorts, sports facilities,changing Rooms,spa, cafe,schools,convenient store,offices,clinics,pharmacy,hygienic occasion,factory showrooms,etc.

The germicidal properties of the UVC light in our desktop portable lamps enable to effectively eliminate 99.99% of bacteria,viruses,fungus and mites within appropriate operational area. There're two types bulbs,38W and 55W, as well as two sterilization options,ozone and ozone-free type. The 38W UVC bulb type is able to disinfect a room up to 30m²(around 3.1m/10.16ft in radius) while 55W UVC bulb type can be up to 60m²(around 4.4m/14.42ft in radius).

UV-C light is harmful for humans and animals under long-time direct irradiation. our UVC disinfection lamps thus are equipped with remote control and auto-off motion sensor. After complete disinfection by our desk top UVC lamp, a sterilized room is safe to enter and there is no worry about SARS-CoV-2(Covid-19) in the air any more.

Remark①:Refer to the detail explanation of Wikipedia. Ultra-Violet (UV) light is invisible to the human eye and is divided into UV-A, UV-B and UV-C.
UV-C is found within 100-280 nm range. In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side. Low pressure UV-C lamps have their main emission at 254 nm where the action on DNA is 85% of the peak value and 80% on the IES curve. As a result, our germicidal lamps are extremely effective in breaking down the DNA of micro-organisms. This means that they cannot replicate and cause disease.
Micro-organisms effective resistance to UV light varies considerably. Moreover, the environment of the particular micro-organism greatly influences the radiation dose needed for its destruction.

PMMA:short for Poly Methyl Methacrylate, formal name of synthetic polymer commonly known as acrylic, acrylic glass, and plexiglass. Before deep processing it is brittle, transparent and of low density. After deep processing it become strong and is able to be available in a wide range of color casting options, textures and forming. Although tt was firstly discovered in 1893 by a French chemist, its commercial application isn't that widespread until 1993 when it was brought into market via Plexiglas.

Ozone type

  • Bulb type:UVC + Ozone (generating O³)
  • UV Wavelength: 185 nm
  • Function: Sterilization and odor removing
  • Advantage: Deeper disinfection and wider reach due to ozone gas can distribute to each corner of a room and remove harmful smell from the room without blocking by obstable in the room.
  • Disadvantage: Ozone cleaning will leave special O³ smell in the room where needs to be ventilated after sterilization as Ozone gas is harmful to respiratory system.
  • Application: washroom, kitchen,pet house,etc,where requires better sterilization.

O³(Ozone):a colorless gas soluble in alkalis and cold water; a strong oxidizing agent; can be produced by electric discharge in oxygen or by the action of ultraviolet radiation on oxygen in the stratosphere

Ozone-free type

  • Bulb type: UVC
  • UV Wavelength: 254 nm
  • Function: Sterilization
  • Advantage: Effective sterilization and doesn't leave any smell. Shorter ventilation time.
  • Disadvantage: Does not remove bad smell from a room and cannot eliminate the virus,bacteria,fungus and bugs behind the shelter because UVC light can be blocked by obstacle.
  • Application: bedroom, living room where people have frequently activity.

Cons and Pros between Ozone type and Ozone-free UV lamp

HOW does the UV-C disinfection lamp work?

Ultraviolet(UV) light is a form of electromagnetic radiation that falls in the region between visible light and X-rays. The wavelength of invisible radiation is from 100nm to 400nm while UVC light spectrum is between 100 nm and 280 nm. UVC at germicidal wavelengths of 254nm has maximal damage to microorganism's DNA/RNA making it cannot reproduce any more. UVC disinfection is used throughout the world in many applications for effectively sterilise atmosphere,killing bacteria, virus, mites, allergic source,fungi and etc.

  • 1. Make sure no humans, pets and plants in the room during UV sterilizing.
    Human protection feature of motion sensor type(radar sensor): the lamp will turn off automatically when people get close within about 3 meters.The lamp will turn on again after people go away from it for more than 3 meters.
  • 2. Place the UVC disinfection lamp at a appropriate height in the centre of a room where UV-C light can reach most of the space in this room.
  • 3. Set disinfection auto-off timer, which can be 15/30/45/60 min.Turn on the UVC disinfection lamp. The lamp has around 10 second delay for the operator to evacuate the room.
  • 4. After complete disinfection, the room gets clean.
  • 5. Ventilate the room for about 15-20 min to scatter odor in the room (if user used Ozone type disinfection lamp) .
  • 6. Caution! Do not stare at the UVC light or stand in front of light for too long because too much exposure of ultraviolet light can cause skin suntan, sunburn,serious conjunctivitis,even blindness.
