Seoul Semiconductor’s LED for Agricultural Lighting in Japan

Seoul Semiconductor Co., Ltd. has supplied LEDs emitting red and blue light to “A” company in Japan, and introduced their advanced technology and products at ‘LED Farming Demonstration Project’ organized by Minister of Economy, Trade & Industry of Japan.

This ‘LED Farming Demonstration Project’ held at the lobby floor has been planned by the local economy & industry group of Minister of Economy, Trade & Industry of Japan in order to inform the possibility of LED as a new farming light source and the new LED-related technology to the public and the officials of that ministry.
Z-Power LED products of this company have been supplied to ‘A’ company which is a major participant in this project, in order to produce LED lighting fixture samples, and 300 thousand pieces will be shipped more.  The products of Seoul Semiconductor used for this project emit red and blue lights, as the artificial light source helping the growth of plants.
A staff of ‘A’ company said, “This project focuses on the LED lighting fixtures for farming which have high brightness LED with high light quantum, and especially optical wavelength of red and blue light can hasten the growth of plants so that enables stable harvesting from vegetable farming.
By participating in this project, Seoul Semiconductor confirmed their competitive power in the Japanese market having advanced technologies, and the possibility to expand the LED market as a lighting source for farming.  This is expected to be a starting point in developing new markets. With artificial light source, the quality and quantity of plants may increase through farming without agricultural chemicals and influence of weather, leading to higher income of farm families. In the past, incandescent lamps, fluorescent lamps and sodium lamps have been mainly used, but in the present time, eco-friendly LED of high efficiency and long lifespan without carbon discharge is being popular. Also Seoul Semiconductor has supplied LEDs for agricultural lighting in Canada.
According to the report of Rural Development Association of Korea, assuming that we cultivate crops with supplementary lighting in about 3,000 ha by using LED, we can get 70% energy saving effect compared to incandescent lamps, which amounts to $12M per year. Especially, farming with artificial lighting became possible even in a dessert or the Artic region. Therefore, it is expected to be helpful to remove food problems over the world.
About Seoul Semiconductor:
Seoul Semiconductor, a world leading LED manufacturer, has been named in Forbes and Business Week's lists as one of the most promising Asian companies.  Its main offering, the Acriche™ LED, was also named "Product of the Year" by Elektronik in 2006, one of the most prestigious electronics publications in Europe. In 2008, this award was given again to Seoul Semiconductor's Flash LED product. Acriche, developed in 2006, is operated directly through AC current without any converters needed for DC LED operation, extending the LED's life span and making installation costs easier and less expensive.  With these important benefits, Acriche LED technology is expected to pioneer the future of the lighting industry. With its cutting-edge technology, Acriche has been awarded in Newtech Korea 2008 and named as Korea Ten Best New Technologies of 2008. Seoul Semiconductor's primary business areas are LED packaging and custom module manufacturing. It provides a full range of LED products including AC-driven semiconductor light sources, Acriche brand products, High-Brightness-Power products, Side-View LEDs, Top LEDs, Chip LEDs, Lamp products, High-Flux LEDs, and custom-type modules. Applications for the company's LED products include general lighting, signage, back lighting for mobile phones, TVs, notebook computers, automotive lighting, home appliances, signals, etc. Seoul Semiconductor reported KRW 284b in sales in 2008. It filed and registered over 5,000. Seoul Semiconductor has 25 branches including 3 overseas corporate offices. Its products are also represented by more than 114 worldwide distributors.
