Samsung Electronics, a world leader in advanced digital component solutions, today announced new horticulture LED lineups, including full-spectrum packages and modules as well as color (monochromatic) LEDs. Optimized for lighting in greenhouses and vertical farming*, the new LEDs provide a broader spectrum of light for healthier plant growth, enhanced farming environments and reduced lighting system costs.

Full-spectrum light encompasses a continuous range of wavelengths from blue and green to red, creating a light blend suitable for horticultural uses. Compared to narrow spectrum lighting, Samsung’s full-spectrum-based LEDs encourage healthier and more balanced plant growth by stimulating photosynthesis, enhancing plant immunity and increasing nutritional value. Additionally, the LEDs can help to improve the overall farming environment by enabling growers to observe plant conditions more easily and spot diseases, like damping-off, at an earlier stage under bright white lighting. As high-efficiency and cost-effective alternatives to higher-priced red LEDs, full-spectrum LEDs can help lower the costs of a grower’s entire lighting system.

“Samsung’s full-spectrum-based horticulture LEDs present a new way of using LED lighting to improve plant cultivation at reduced system costs,” said Un Soo Kim, senior vice president of LED Business Team at Samsung Electronics. “We plan to further expand our horticulture offerings by integrating the latest in smart LED lighting technology, including Samsung’s leading sensor and connectivity solutions.”

In addition to its full-spectrum white LEDs, Samsung has added blue, red and far-red LEDs to its horticulture family to offer an extensive variety of wavelength combinations and meet the different design needs of horticulture lighting manufacturers.

Built on Samsung’s market-proven LED technologies, the new full spectrum and color LED lineups feature a high degree of reliability, making them well-suited to withstand high temperatures and humidity levels as well as agricultural chemicals used in greenhouses and vertical farming.

Samsung’s horticulture LED packages are now in mass production for lighting manufacturers and growers worldwide. The modules will become available in the first quarter of 2019.

Samsung’s New Horticulture LED Lineups:

* Vertical farming is the practice of growing crops in vertically stacked layers and usually takes place in controlled, indoor environments.

** PPF (photosynthetic photon flux) indicates the total amount of photons in the photosynthetically active radiation (PAR) range – a spectral range between 400 and 700nm – that can enhance plant photosynthesis and is measured in micromoles per second (μmol/s).

*** PE (photon efficacy) indicates the light efficacy level for photosynthesis in plants and is measured in micromoles per joule (μmol/J).

Samsung Electronics, a world leader in advanced digital component solutions, today announced that it is now offering LED component solutions that have been optimized for horticulture lighting. The company’s new horticulture LED lineup features a newly developed “red LED” package, as well as additions to key existing Samsung “white LED” package and module families to include horticulture lighting specifications.

“Our horticulture LED solutions are based on LED technologies that deliver proven levels of performance and reliability across an extensive range of lighting applications,” said Yoonjoon Choi, vice president of LED Business Team at Samsung Electronics. “By broadening our lineup to include horticulture LEDs, we are providing global luminaire manufacturers with a one-stop resource for these solutions as well as for our many other LED technologies.”

Samsung’s new horticultural LED – the LH351B Red – is a high-power package providing a wavelength of 660 nanometers (nm) with a photosynthetic photon flux (PPF)* value of 2.15 micromoles per second (μmol/s) (350mA), making it optimal for most types of horticulture lighting. The 660-nm wavelength helps to accelerate the growing of plants including their photosynthesis, as well as enrich the blooming of flowers. The package also features a very low thermal resistance of 2.0 kelvins per watt (K/W), allowing for easier heat dissipation within LED luminaires. Moreover, the LH351B Red uses the same electrode pad design as its LH351 series counterparts, enabling greater PCB design flexibility in luminaire manufacturing.

Beyond its new LH351B Red offering, Samsung has added horticulture specifications to its mid-power packages – LM301B; LM561C, and two linear modules – Q-series and H inFlux. These LED component families now include PPF values of 0.52μmol/s (65mA), 0.49μmol/s (65mA), 24μmol/s (0.45A, 21.9V) and 114μmol/s (1.38A, 46.9V), respectively.

In addition, the white LED packages and modules feature extremely high light efficacy of 2.92 micromoles per joule (μmol/J) (65mA), 2.72μmol/J (65mA), 2.43μmol/J (0.45A, 21.9V) and 1.76μmol/J (1.38A, 46.9V), respectively, while the LH351B Red delivers 3.13μmol/J (350mA). These high efficacy levels minimize the impact of lighting on ambient temperatures, allowing growers to better control temperatures in almost any greenhouse environment and save on energy costs.

Samples of Samsung’s horticulture LEDs are available now and will be showcased at LIGHTFAIR International 2018 (booth #1112) in Chicago, Illinois (USA), May 8-10.
