Osram Opto Semiconductors, a subsidiary of Siemens, has developed an efficient LED based on the thin-film technology that is utilized for high power semiconductor chips. The red LED features an emission curve that closely matches the spectral sensitivity of chlorophyll.
LED Used for Horticulture
The LED unit comes in two kinds of variants, each of them having a different beam angle. The Oslon SSL LED has an 80º beam angle and is ideal for multi-level applications such as lettuce cultivation.
The Golden Dragon Plus LED has a 70º beam angle and is suitable for utilization in reflector lamps for lighting up large regions under cultivation. The LED light also has the ability to encourage a plant’s growth phase under cultivation.
The luminous efficiency of a lighting solution is 60% higher with blue and red LEDs, when compared to traditional sodium lamps. The LEDs have a service life of 100,000 hours and offer maintenance-free operation for several years. Osram was also involved in a pilot project with Fiona Lighting and Arrow Electronics for commercial horticulture.
