When it comes to horticulture lighting growers often face light uniformity issues with the Pitch-to- Distance ratio. Growers currently try to close the lighting gaps with a higher number of luminaires or accept that some plants receive more light than others. This is not a satisfying solution because the main aim for the grower is to get the highest possible yield at the lowest possible cost. To address this issue, ams OSRAM combined its established and industry leading Oslon Square LED for horti- culture lighting with a new innovative primary optic.
The new batwing optics enables a special radiation pattern of light that looks like wings. The wide beam angle of 140° and the rectangular shape of light distribution enables higher uniformity and an optimum utilization of space in greenhouses. The wider angle also allows for a larger distance be- tween the luminaires and thus a possible reduction of fixtures. Compared to lighting systems using LEDs with a secondary Bat Wing optics, the primary Bat Wing lens solution can offer an up to 5% higher system efficiency.
The Oslon Square family is now extended with four new devices – hyper red (660nm), deep blue (450nm), far red (730nm) and horti white – covering all necessary wavelengths for horticulture appli- cations. All versions feature a compact footprint of only 3,0 mm x 3,0 mm and convince with an ex- cellent radiant flux maintenance and outstanding lifetime of more than 102,000 hrs. Besides this the products come with industry leading efficacy values. The hyper red version achieves an optical out- put of 1042 mW at 700 mA causing a Wall-Plug-Efficiency (WPE) of 74%.
