Samsung’s new horticultural LED – the LH351B Red – is a high-power package providing a wavelength of 660nm with a photosynthetic photon flux (PPF) value of 2.15 micromoles per second (μmol/s) at 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.
