Samsung has announced that it is now offering LED component solutions that have been optimised 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.
The company’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). 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. Additionally, 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, the Korean tech conglomerate has added horticulture specifications to its mid-power packages – LM301B; LM561C, and two linear modules – Q-series and H inFlux.
Further, 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), Samsung said. These high efficacy levels minimise the impact of lighting on ambient temperatures, allowing growers to better control temperatures in almost any greenhouse environment and save on energy costs.
Samsung is currently showcasing this horticultural LED components at LIGHTFAIR International 2018 in Chicago, Illinois.
