Mar 10, 2017: Basil grower Servizi Ambientali Bassa Reggiana (S.A.BA.R.) in Italy has been able to reduce energy consumption by 56% by deploying LED lighting in greenhouses used for basil production. This is in comparison to high-pressure sodium (HPS) lighting used previously.
Servizi Ambientali has also increased yield with the help of a five-day-shorter production cycle, thanks to LED lighting. The LED fixtures that were used are developed by Ambra Elettronica
Osram LEDs reduce production cycle & energy
Ambra is a member of the Osram LED Light For you (LLFY) SSL-centric partnership program. It manufactures LED horticulture lighting products, which includes 42W AE32 fixture for vertical farming—a range of linear products for greenhouse applications—and 200W AE200 rectangular fixtures that provides intensity in a focused area.
Ambra Elettronica has used Osram LEDs in its horticultural lighting fixtures to reduce the basil production cycle and cut down on energy consumption.
Basil greenhouse depends on AE80 linear fixture that measures 1200 mm in length. It is a of 100W and can deliver PAR (photosynthetically active radiation)-spectrum photosynthetic photon flux (PPF) of 210–230 μmoles/sec, as per the LEDs used in the product.
Ambra provides different mixes of 450-nm blue, 620-nm red, 660-nm hyper-red, and 730-nm far-red Osram Oslon LEDs. The fixture has an efficiency of 2.2 μmoles/J.
The basil grower said earlier HPS lighting required 32 kW of power but with LED lighting, it has been reduced to 14 kW, with an annual energy savings of 75,000 kWh. According to Osram, this means 30 tons of carbon emissions. More importantly, the production cycle of basil has been reduced by five days for each crop cycle.
By using Osram’s Oslon LEDs with red, hyper red, and blue in different proportions, the basil grower could increase the crop yield. LED lighting could also solve the problem of proliferation as the peronospara fungus was previously eradicated by the heat generated by HPS lighting, which was not observed with LED lighting.
Back in 2015, Osram was the first to manufacturer far-red LED. It had earlier offered blue, red and hyper-red LEDs that are used to match plant chlorophyll absorption and to have good impact on photosynthesis. Far-red LEDs are used to manipulate plant growth and flowering.
