Bright idea from Danish lighting firm saves plant growers money

Fionia Lighting A/S has developed an energy-saving LED-based technology that enables professional nursery gardeners to significantly cut lighting costs without compromising plant growth
Fionia Lighting A/S, a Funen-based company specialising in LED lighting for the horticultural industry, has scooped an award from the Ministry of Climate and Energy for developing an energy-saving technology that enables professional nursery gardeners to significantly cut lighting costs without compromising plant growth, reports professional journal Ingeniøren (The Engineer).
 
Over the past three years, Fionia Lighting has developed a complete system of LED-based lighting that optimises energy uptake by plants. Development engineer Thomas Rubæk told Ingeniøren: "We have spent a long time learning about the wavelengths of light that plants can utilise. And there are differences. Some plants require a different wavelength mix than others. For example, tomatoes have completely different needs to roses."
 
Fionia Lighting's system uses electronics that tune the LEDs to produce the required blend of wavelengths, which saves on energy by avoiding the wasteful generation of light wavelengths that the plants cannot use. LEDs also take only a fraction of a second to warm up to operating temperature, whereas the conventional sodium lamps used by nursery gardeners need around half an hour.
 
Fionia Lighting was founded last year as a spin-out from the University of Southern Denmark, and is located in the city of Odense in the heart of Denmark's pot plant industry. The company points out that its name is taken from the Latin word for island of Funen, and that Fionia Lighting has no connection with the currently troubled Fionia Bank.
