Würth Elektronik eiSos presents WL-SMDC – the new mono-color ceramic LEDs for SMT assembly – optimally tailored to requirements in artificially illuminated greenhouses. Besides manufacturing products in the common colors of blue, yellow, green and red, these LEDs are also available in the wavelengths 450 nm (Deep Blue), 660 nm (Hyper Red) and 730 nm (Far Red). The emissions spectra of these horticulture LEDs correlates optimally with the absorption spectra of plant photosynthesis pigments.

The horticulture LEDs from Würth Elektronik eiSos are distinguished by high efficiency and brightness, as well as by outstanding PPF values – the Photosynthetic Photon Flux determines the energy that plants can draw from LED light. The LEDs have a low thermal resistance, an electrically neutral heat path and also offer convincing advantages through their small package size (3535) and low power loss.

While red and blue light provides plants with the most energy, different wavelengths control other growth processes. This fact is used in plant breeding with a controllable individual “light mix”. For instance, far red light (720-740 nm) in the infrared spectrum influences germination. This wavelength range can shorten the flowering time of plants, and promote elongation growth. The horticulture LEDs from Würth Elektronik eiSos provide manufacturers of horticultural lighting systems with LED selection and configuration to optimally match light spectra to certain plants. All articles of the WL-SMDC series are available from stock. Free samples are available on request.
