Demonstration and integration of energy saving LED luminaires for greenhouses
The aim of this project is to demonstrate and improve on a light emitting diode (LED) luminaire for integration into professional nursery gardens. This project is a continuation of a EUDP project documenting the benefits of changing from traditional supplemental lighting to LEDs. The project includes a large-scale demonstration site covering 1500 m2 equipped with LED luminaires. Corresponding to a whole greenhouse, the size ensures full control of all parameters, such as leaf temperature, CO2 concentration and chemical usage, enabling us to find solutions for overcoming integration barriers such as climate computer compatibility, heat distribution and novel nursing techniques. The 1500 m2 climate zone will be the focal point of our demonstration facility, but also the strategic starting point of our next development phase leading to a sales ready product. Furthermore, the facility is envisaged to demonstrate the luminaires’ energy savings, robustness and reliability on a large scale. Coupled with further improvements in luminaire design, the total integration of the LED lighting system into the greenhouse setting will result in a market ready LED luminaire with a demonstrated 50% saving in energy consumption, corresponding to an annual saving of 4 – 5 MDKK for the average nursery gardener
The aim of the project was to construct and test an LED luminaire production in nurseries. The tests were made both in full and in a research environment with a focus on energy conservation and plant reaction.
The result of the project was an installation with 224 FL300 fixtures on a 1500 m2 production area in the nursery PKM. The fixtures were controlled with a LCC 4 Climate computer where both the intensity and spectra could be varied. The luminaires showed both a good stability, light stability and plant quality.
Plant results from all three test methods in this EUDP project proved two important results beyond energy savings of 40-50%. One result, the ability to control plant growth by the amount of blue light, which reduce the use of chemicals. Second, the ability to control the intensity of illumination during the day, which had a large influence on the output was stable.
The Danish nurseries spend about 200 GWh for lighting every year and CO2 emissions from accounts for about 470,000 tons each year. In this particular horticulture, the new energy efficient luminaires lead to a halving of the electricity bill equivalent to a saving of about 7 million. kr. pr. year.The firm Fionia Lighting, which produces the new FL300 luminaires, has entered into a strategic partnership with Senmatic which include Seller climate computers. PKM welcomes foreign visitors for viewing in EUDP project developed lighting solutions. The newly developed FL300 luminaire won in September 2014 award as "Best Professional Equipment" at an exhibition in England.
