The interest in LED lighting for horticulture applications has dramatically increased as the catalyst for plant growth. The main advantage of LEDs stems from their ability to generate specific wavelengths of light that are tuned to specific crop growth.
Würth Elektronik is helping manufacturers of horticultural lighting systems with new Horticultural LEDs that are optimally tailored to requirements in artificially illuminated greenhouses. The WL-SMDC unveiled by the firm are new mono-color ceramic LEDs for SMT assembly.
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 firm noted that these horticulture LEDs provide manufacturers with LED selection and configuration to optimally match light spectra to certain plants.
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.
As claimed by the firm, the notable features of these horticulture LEDs are their high efficiency and brightness, as well as outstanding PPF values. The Photosynthetic Photon Flux (PPF) determines the energy that plants can draw from LED light.
The LEDs are said to 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.
