New LED Lighting Products Accelerate The Growth Of Plants

The interest in Light Emitting Diode (LED) lighting technology for horticultural lighting is picking up to grow healthier plants and maximize yields. Some benefits for their use include improvement in operating costs achieved through energy savings, long lifetime and low maintenance needs. LEDs can also be tailored to meet the spectrum needs of specific plants.

Looking at this growing demand, Samsung has stepped into the horticulture LED arena with its newly developed “red LED” package optimized for Horticultural applications. The company has also made additions to its existing “white LED” package and modules to include horticulture lighting specifications.

New 660nm LED Optimised For Horticulture Applications

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) when operating at 350mA. This makes it optimal for most types of horticulture lighting.


The company says that “660nm 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, according to the firm.

Moreover, the LH351B Red uses the same electrode pad design as its LH351 series counterparts, enabling greater PCB design flexibility in luminaire manufacturing.

Certain Existing White LEDs Upgraded For Horticultural Applications 

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).

Samsung asserts: “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.”

“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.” 


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