    Disinfection for air, surfaces and water

    The challenge

    The quality of the air we breathe, the cleanness of surfaces and objects we touch, and the purity of water we drink have a profound effect on our health and well-being. We’re all at risk of contracting and spreading viruses and bacteria, especially in busy public areas like the shops, offices, factories,  bars or restaurants, schools, museums and on public transport.

    UV-C radiation is a known disinfectant for air, water and surfaces that can help mitigate the risk of acquiring an infection and has been used extensively for more than 40 years1. All bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection2. In laboratory testing, our UV-C light sources inactivated 99% of SARS-CoV-2 virus 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.

    range of Philips UV-C lamps, luminaires, devices, control systems and services
    Over the past 35 years we’ve developed strong UV-C application expertise. It has allowed us to develop a broad range of effective UV-C lamps, luminaires, devices, control systems and services. These can be used in a variety of air, surface, object and water disinfection applications. Our new luminaire range includes upper air luminaires that disinfect passing air, open UV-C luminaires and UV-C trolleys that disinfect rooms and locations when no-one is present, and UV-C chambers that disinfect objects.

    What is UV technology?


    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. Philips 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 disease4.

    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.

    Service and support


    Building on 35 years experience in UV-C technology, we provide design-in and lifecycle services to help effective disinfection during planning, design, build, operation, maintenance and optimization of the UV-C system.
    Safety icon

    Safety in mind


    As direct exposure to UV-C light is harmful, our UV-C products are delivered with a range of safeguards and instructions. They come with physically integrated equipment or time safeguards, such as presence or motion detection sensors or timers, or otherwise they are to be installed with containment safeguards to enable safe operation. Also we provide extensive training and certification programs to help ensure correct installation, usage and maintenance.

    Application fields

     

    We offer a full range of UV lamps, luminaires, chambers and control systems that are suitable for use in air, surface, objects and water disinfection; both for residential and professional applications.

    A word of caution


    UV-C lighting presents minimum risk when used in the correct way. Direct exposure to UV-C is dangerous. The lighting must always be installed with adequate shields and safeguards (such as presence detection sensors or timers) to avoid light damage and severe injuries to the eyes and skin. The UV-C disinfection luminaires we provide without such safeguards are intended only to be used as components in disinfection systems that contain any safeguards indicated, but not limited to, those specified in mounting instructions and user manuals.

    Philips UV-C disinfection luminaires must only be sold by Signify or through qualified partners and installed by qualified professionals according to our stringent safety and legal requirements.

    None of our UV-C lamps are certified or approved as a medical device anywhere in the world and should not be used as such. They should never be used in applications or activities that may cause and/or lead to death, personal injury and/or damage to the environment.

Data made available to us by the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University, which has been collected from a laboratory experiment conducted by Dr. Anthony Griffiths (Associate Professor of Microbiology at Boston University School of Medicine) and his team at the premises of the NEIDL (such data will be the subject of a forthcoming scientific publication by Boston University), shows that Signify’s UV-C light sources irradiating the surface of a material inoculated with SARS-CoV-2 (the virus that causes the COVID-19 disease) at a UV-C dose of 5mJ/cm2 (exposure time 6 seconds) resulted in a 99% reduction of the SARS-CoV-2 virus present on that surface. This study determined that a UV-C dose of 22mJ/cm2 results in a reduction of 99.9999% of SARS-CoV-2 virus on that surface (exposure time 25 seconds). Research variables are available upon request.
