SDK revolutionizes the grow-light business
Japan Inc. has been touting farming in concrete bunkers and urban high rises as way to counter the Japan’s problem of having the world’s least efficient and unprofitable agricultural sector. SDK Corporation has advanced this damp-dreaming by producing LED grow lights that are 70% more efficient than previous technologies.
Apr 3, 2009 –Nikkei Electronics Asia– Tech-On! Showa Denko KK (SDK) has introduced aluminum-gallium-indium-phosphide (AlGaInP) LED chips that emit red light with a wavelength of 660nm, claimed to be the optimum light for accelerating the growth of plants…efficiency of LED lamps using the AlGaInP chips is claimed to be about three times as high as that of conventional red LED lamps ...more...
According to the SDK press release:
“….facilities for growing vegetables in an environment of controlled lighting, temperature, humidity, CO2 concentration and nourishment are attracting attention as they ensure stabilized production regardless of season or place, and realize multiple cropping. Furthermore, they do not need fungicides or insecticides because of the controlled environment. Nearly 30 facilities of this kind are already in operation in Japan….more...”
Recent research suggests that the ideal balance essential for plant growth is 92% red LEDs and 8% blue LEDs—grow lamps providing white light are a waste of electricity.
