South Korean firm Samsung has officially stepped into the horticultural LED component realm with the release of a new Red LED package optimized for Horticultural applications. Additionally the company has begun including horticultural specifications with certain existing white LED components. The company unveiled new Red LED and the key white LED components for horticulture at LIGHTFAIR.
“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 newly developed high-power horticultural LED package, the LH351B Red, delivers a wavelength of 660 nanometers (nm) with a measure of photosynthetically active radiation known as photosynthetic photon flux (PPF) of 2.15 micromoles per second (μmol/s) when operating at (350mA). The company says that this PPF makes it optimal for most types of horticulture lighting.
Additionally, the company asserts that the 660-nm wavelength helps to accelerate plant growth including speeding photosynthesis and enhancing the blooming of flowers.
The package’s very low thermal resistance of 2.0 kelvins per watt (K/W), is said to allow easier heat dissipation within LED luminaires. Furthermore, the LH351B Red employs the same electrode pad design as its LH351 series equivalents, increasing PCB design flexibility in luminaire manufacturing.
Adds Horticultural LED Specifications to Certain Existing White LEDs
In addition to its new LH351B Red product for horticulture, Samsung has added horticulture specifications to its mid-power packages white LED packages LM301B; LM561C, and two linear white LED modules — the Q-series and H inFlux. According to Samsung these 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 boast the 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. The LH351B Red delivers 3.13μmol/J while operating at 350mA. The company points out that these high efficacy levels minimize the impact the LEDs on ambient temperatures in plant growth environments. So, in addition to saving on energy costs, the LEDs give growers better control of temperatures in almost any greenhouse environment.
Samsung is showcasing this horticultural LED components at LIGHTFAIR (booth #1112), and these horticulture LEDs are available now.
