Expanded product range for horticultural lighting with a “far red” version
OSRAM Opto Semiconductors is expanding its LED product range for horticultural lighting with a new type of the well-proven OSLON SSL. In addition to the existing hyper red (660 nm) and deep blue (450 nm) versions, the high-tech company developed a far red OSLON SSL LED with a wavelength of 730 nm. For certain plants such as tomatoes, peppers or roses, it is exactly this wavelength which leads to better growth. Customers now have a better coverage of the color spectrum for their horticulture applications with this new LED now available.
The new ultra compact OSLON SSL (3 mm x 3 mm x 2.35 mm) is available in two new product versions with a narrow beam angle of 80° and 150°. Because of these features, the LEDs can be arranged close to one another for uniform light distribution. All OSLON SSL versions can be combined easily because of the same size footprint and solder pad, as well as the same technical characteristics. This offers high design flexibility for ambitious horticultural lighting applications where each greenhouse lighting system needs a tailor made solution.
LED lighting can stimulate plant growth by up to 40 percent. Different wavelengths address different plant properties: blue light supports flowers to open up and red light helps stems to grow better. Thus, a combination of the three existing versions of the OSLON SSL LED family, far red (730 nm), hyper red (660 nm) and deep blue (450 nm), provides better coverage of the color spectrum and an optimal growth pattern. With this range of three colors, the customers can address a large variety of plants.
There are several general benefits of LEDs for use in horticultural lighting. Because of the individual LEDs, the lighting can easily be steered and controlled in the greenhouses. LEDs have a longer lifetime than other lighting technologies; they are very energy-efficient and thus drastically reduce energy consumption over time. They also emit no heat in the direction of the light so the plants will not be damaged. Furthermore, LEDs are available in different wavelengths and lighting solutions can be adjusted to the exact value the respective plant needs.
