By looking at crops’ light requirements, it is immediately obvious based on absorption data to see that the light used today in the form of high-pressure sodium lamps, etc., is not designed for plants. This obsolete technology with a basis in street lighting can beneficially be replaced by highly intelligent LED luminaires that can be integrated logically and simply into all modern professional nursery gardens.
Integrated energy solutions
Fionia Lighting is focused on developing a complete energy solution, where energy savings from the use of LEDs is combined with the recovery of surplus heat, measurement of natural light from the sun and intelligent control of the luminaires. The LED luminaires can be incorporated into the individual nursery’s energy system, where the recovered heat can be used directly in existing installations or stored for use at other times of the day or year: in the morning or in winter, for example.
Adaptive light control
Today’s traditional greenhouse luminaires cannot be controlled intelligently, which leads to them either being turned on at full power or turned off completely. Gardeners have shown interest in a solution, where they can adjust the output of the lamps according to the level of natural daylight and the demands of the crops. One could imagine a scenario where a gardener would like to retain 20% of growth light in the period from 2pm to 5pm.This requirement could be fulfilled by an intelligent LED luminaire to the benefit of the gardener’s electricity bill and production. Furthermore, LED technology can be used to both compensate for seasonal variations in spectral composition of sunlight and to control plant morphology.
Plant appearance
Currently, plant appearance is a question of time and chemical use. With accurately measured luminaires from Fionia Lighting, each gardener can dictate the appearance of his crop within the physiological framework of the plant. LEDs make it possible to change the plant's ability to sprout, bud and form side shoots, but also to alter the relationship between height and compactness. Ergo if compact rose plants with numerous side shoots and many buds are required, then one kind of light is supplied, while if focus is on fruit yield from tomato plants a different kind of light is used. Plants cannot be changed radically, but they can be influenced to give the desired responses.
