What plants want: LED technology helps provide fresh food

During dark season, many of us experience the effects of not getting enough light. As soon as the days get shorter, we feel more tired and exhausted. Plants are in a similar situation - when they don't get enough light, their photosynthesis doesn't work sufficiently.

Plants predominantly need red (640 to 700 nm) and blue light (400 to 490 nm) for their growth. For example, red light promotes the production of biomass in plants.

The new generation of the Oslon Square Hyper Red with a wavelength of 660 nm is the flagship product in Osram Opto Semiconductors' comprehensive Horticulture portfolio. In addition to the efficiency values, greenhouse operators benefit from a radiant flux of 1.030 mW at 73% WPE (wall-plug efficiency) and a photon flux of 5.7 µmol/s at an efficacy of 4.0 µmol/J at 700 mA. For applications with higher efficacy requirements, LED provides 78% at a driving current of 350 mA and 80% at 250 mA with an efficiency of 4.6 µmol/J.

"Horticulture lighting is an absolute growth market, which we have been leading for many years by providing more and constantly improved products," explains Yong Sheng Chew, Product Manager at Osram Opto Semiconductors. "The significantly improved efficiency values help our customers save energy. Thanks to the proven compact footprint of 3.0 mm x 3.0 mm, greenhouse owners can easily bring existing lighting systems up to date with the latest LED technology".
