UV Light and Photon Disinfection

As healthcare professionals, our top priority is the safety and well-being of our patients and staff. One of the most significant challenges we face in healthcare settings is the risk of hospital-acquired infections (HAIs). These infections can lead to serious complications, prolonged hospital stays, and even loss of life. Fortunately, advancements in technology have provided us with powerful tools to combat this issue effectively. Among these innovations, Ultraviolet (UV) light and photon disinfection have emerged as game-changers in infection prevention. In this article, we’ll explore the science behind UV-C technology, its effectiveness, and how it can be integrated into hospital and aged care settings.

How does a UVC Light Disinfection work?

UV disinfection is based on the principle that short-wavelength ultraviolet light can penetrate the cell walls of microorganisms, such as bacteria and viruses, and damage their DNA or RNA. This process disrupts their ability to replicate and render them inactive, ultimately preventing their spread and reducing the risk of infection.

These lamps are strategically placed in hospital rooms, operating theatres, waiting areas, and other critical spaces. When turned on, the UV-C light irradiates surfaces and air, effectively killing harmful pathogens.

Is it necessary to use UV light for disinfection against outbreaks?

Given the global impact of the COVID-19 pandemic, there has been increased interest in UV-C disinfection as a potential tool to combat virus outbreaks. While UV-C has shown promise in inactivating SARS-CoV-2 and any other type of viruses, it should be noted that it is not a standalone solution. Infection prevention measures such as hand hygiene, personal protective equipment (PPE),and proper ventilation remain critical in mitigating the spread of the virus. However, Ultraviolet disinfection can complement these measures by providing an additional layer of protection against airborne and surface pathogens.

How effective are smart UV light for disinfection?

UV technology, equipped with advanced sensors and technology, have gained popularity in recent years due to their ease of use and efficiency. These lamps can intelligently detect the presence of people in a room and automatically turn off or adjust their output to prevent direct exposure. This feature makes them safe and user-friendly for surface disinfection, room disinfection, or in other busy hospital environments.

Integration into Healthcare Facilities

Implementing UV-C disinfection in healthcare facilities requires a thoughtful and well-structured approach. Facility managers, infection control managers, environmental services managers, and directors of nursing play a crucial role in the successful integration of this technology. Here are some key steps to consider:

Risk Assessment:

Conduct a thorough risk assessment to identify high-risk areas within the facility. Operating rooms, isolation rooms, patient wards, and high-traffic waiting areas are examples of places that may benefit from UV-C disinfection.

Training and Education:

Ensure that staff members are well-trained on the proper use and safety protocols related to UV disinfection. It is essential to follow manufacturer guidelines and best practices to minimize the risk of accidental exposure.

Complementing Infection Control

UV technology should be seen as a complement to existing infection control practices, not a replacement. Reinforce the importance of hand hygiene, surface cleaning, and other standard precautions.

Monitoring and Evaluation

Regularly monitor the effectiveness of UV disinfection through environmental monitoring and infection surveillance. This data can help fine-tune the approach and demonstrate the impact of the technology.

Smart UV Lamp: Safety Measures and Precautions

When incorporating UV into healthcare settings, certain safety measures and precautions must be strictly adhered to:

  • Signage: Clearly mark areas undergoing UV disinfection with appropriate warning signs to prevent accidental exposure.
  • Time Management: Set up automated timers to control the duration of Ultraviolet exposure and ensure sufficient disinfection without unnecessary risk.
  • Occupancy Sensors: Install occupancy sensors to automatically deactivate devices when people are present in the room.
  • Personal Protective Equipment (PPE): Ensure that staff members wear appropriate PPE, such as gloves and eye protection, when handling Ultraviolet equipment.
  • Maintenance and Calibration: Regularly maintain and calibrate UV devices to ensure they are functioning correctly and emitting the appropriate wavelength for effective disinfection.

How About Disinfection In Populated Indoor Space?

While UV-C is excellent at killing bacteria and viruses, it can also be harmful to humans when directly exposed to skin and eyes. Prolonged exposure can lead to sunburn-like symptoms and damage to the cornea. Therefore, UV-C disinfection is best suited for controlled environments, such as hospitals and aged care facilities, where human exposure can be minimised.

Similar to UV technology, photon disinfection technology is also utilising atomic UV photon particles to eliminate harmful pathogens, yet is a safe indispensable tool in combating the spread of infections in
populated indoor spaces.

If UV technology operates by destroying viruses, Photon disinfection operates by deactivating the viruses by releasing trillions of negatively charged photon electrons to interact with the negative-seeking spike proteins of viruses. This will then prevent viruses from infecting humans, reducing viral transmission in the air and on surfaces. These systems are designed to target a wide range of pathogens, from bacteria to viruses, ensuring comprehensive disinfection.

This offers a reliable and rapid solution to disinfect healthcare environments when patient is in the room. By deploying Photon technology, hospitals can maintain a sterile environment, contributing to better infection control practices and improved patient outcomes.


UV-C and Photon technology hold immense promise in reducing hospital-acquired infections and improving patient safety. By leveraging the power of UV light and photon disinfection, healthcare facilities can add an extra layer of protection against harmful pathogens. However, it is essential to implement this technology with caution and follow strict safety guidelines to prevent harm to both patients and staff.
