Strathclyde signs licencing agreement for pioneering HINS-light technology


Linea Light Group presents an antibacterial light that protects everyday health and wellbeing in any setting

The new Environment Care Lighting technology range created by Linea Light Group using High Intensity Narrow Spectrum (HINS) light developed and patented by the University of Strathclyde in Glasgow, will enable the Woofer and Rollip appliances from the i-LèD Professional collection to decontaminate surfaces and prevent infection, destroying up to 70-80% of bacteria with continuous use.

By using a light wavelength of 405 mm, the Environment Care Lighting can light and decontaminate rooms, avoiding the need for more expensive Ultraviolet technologies which use frequencies between 240 and 260 nm, require rooms to be empty during disinfection, and can cause degradation effects on photosensitive mater

The action of two light sources, a violet-blue-dominated LED combined with a white power LED, enables the Environment Care Lighting technology to offer two functions at the same time: lighting and protection of human health.

Linea Light Group will be the first European-based company to use the HINS-light patent in combination with lighting appliances, making it available for the Woofer and Rollip collections. Thanks to the exceptional versatility of Linea Light Group products, these new functions can be used in offices and public spaces, hospitals and healthcare settings and residential areas and multi-purpose buildings.

The HINS-light technology was developed in The Robertson Trust Laboratory for Electronic Sterilisation Technologies (ROLEST) at the University of Strathclyde thanks to the work of a team of experts led by Professor Scott MacGregor, Vice-Principal of the University, with Professor John G Anderson, Dr Michelle Maclean and Professor Gerry Woolsey.

Gianluca Salciccia, Linea Light Group’s Sales Director, said: “Linea Light Group’s approach to luminaire design has always been unconventional, and we have a new way of thinking about the product that allows our R&D team the freedom to be creative.

“Experts in microelectronics, geometric optics, material science, digital information technology, and developers of mechanical prototypes and specialized machine operators speak daily with fashion designers, supermarket managers, executives of large hotel chains and of course professionals such as architects and lighting designers, to create innovative products for technology and application.

“Linea Light Group’s products and projects put people in the spotlight. Lighting technology can be an important tool for wellbeing and improving people’s quality of life. Linea Light Group’s new Environment Care Lighting light range could also add a third dimension of physical wellbeing, with products capable of decontaminating the environments in which people live and work, protecting their health”.

Professor John G. Anderson, Research Fellow in Electronic & Electrical Engineering at the University of Strathclyde and a member of the HINS-light technology research team, said: “The Environment Care Lighting represents a unique method of disinfection as it does not employ harmful chemicals or dangerous UV light but instead uses only visible light which is harmless to humans.

“The system works by using selected visible wavelengths which activate light sensitive molecules contained within microbes. This process creates biocidal chemicals which are lethal to bacteria such as methicillin-resistant Staphylococcus aureus, or MRSA, and Clostridium difficile, known as C.diff. The process can be operated continuously to achieve whole room disinfection in both the presence or absence of occupants.”

Professor Scott MacGregor from the University of Strathclyde said: “HINS-light technology is a great example of how the University of Strathclyde is producing innovation that also benefits society. The technology is harmless to people, so it can be used continuously in different spaces, thus improving disinfection and preventing the spread of infection. Linea Light Group’s new Environment Care Lighting products means that many more people in healthcare, public spaces and in commercial, work and residential environments can benefit from this technology.”

About University of Strathclyde

The University of Strathclyde is a leading international technological university based in the centre of Glasgow, founded in 1796 as the Andersonian Institute,

Inspired by our founding principle as ‘a place of useful learning’, our mission is to make a positive difference to the lives of our students, to society and to the world. Strathclyde students benefit from an innovative and practical educational experience enhanced by its integration with our research capabilities, high-quality academic resources and an unparalleled industry engagement programme. The excellence of our research is evidenced by our position amongst the UK’s top 20 research-intensive universities, according to the Times Higher Education’s analysis of REF2014, and by the growth in range and scale of our research collaborations.

We have also redefined how we collaborate and work with industry, government and the third sector to ensure innovation and knowledge exchange are fundamental activities that deliver tangible impact. Strathclyde was named the Times Higher Education UK University of the Year 2019, the Sunday Times Good University Guide Scottish University of the Year 2020 and in November 2019 was awarded a Queen’s Anniversary Prize for Higher and Further Education for its excellence in energy innovation.

The University of Strathclyde’s flagship entrepreneurship programme, Strathclyde Inspire, supports and encourages entrepreneurship for all. It’s available to students, staff and alumni who want to explore their entrepreneurial potential, start a business or commercialise their research, and provides support at every stage of the entrepreneurial journey.

The launch of Strathclyde’s new five-year Entrepreneurship Strategy to 2025 sets out the University’s plans to transform entrepreneurship.

About Linea Light Group

In 1976 it was Minulamp, specialised in components for light fixtures; then, thanks to the union with other realities in Veneto, in 1985 the current name, Linea Light Group, was born. At the beginning of 2000, the Treviso-based company was one of the first companies in Europe to be specialized in LED technology, the perfect answer to the needs of energy efficiency, lighting efficiency, color fidelity and design versatility. The experience gained over the years has allowed us to acquire cutting-edge know-how with Made in Italy design, electronics made entirely in-house and an R&D department consisting of 85 dedicated professionals. With 6 production plants, 20 offices worldwide and more than 550 employees, today Linea Light Group is distinguished for its mission that is attentive to the peculiarities and needs of local partners in a “Think global, act local” perspective, guaranteeing global coverage and offering personalized and timely service worldwide.
