Detail Company Introduction
Zhejiang DaYi Electron Co, .Ltd, whose predecessor was Wenzhou DaYi Electron Co, .Ltd located in Wenzhou high and new technology industrial development zone is a high-tech enterprise which specializes in and integrates the R&D (research and development), manufacture, and sales of LED products. As the first enterprise in China dealing with the distribution and mass production of hi-power LED street lamp over 100W, DAYI has been offered six patents by country and has successively developed both the outdoor and indoor LED illumination products in more than one year, such as LED street lamp, LED courtyard lamp, etc of the outdoor illumination series and LED bulbs, LED daylight Lamp, etc of indoor ones. Our Illumination White LED street lamps (1W-120W), the most advanced and environment-friendly illumination over the world, especially the hi-power ones (30W-120W) lead the way worldwide and are widely used in the city lightening, illumination in road and tunnel, outdoor and indoor illumination, decoration, and also fit in the solar and wind energy driven system. We launched the R&D of semiconductor white illumination since Mar.2006 and finally have managed to solve the difficulty of heat dissipation in hi-power LED by repeated experiment and continual improvement both in the radiation and driving circuit of semiconductor, which are considered as bottlenecks in this industry, as contains the great effort of our technical staff. The solution of this problem ensures that the increase of temperature in operating components will be somewhere around 20 degree C . Our LED street lamps worked in many projects held in Beijing, the provinces of Hebe, Xinjiang, Jilin, etc and have been sold on occident and east-southern-Asian markets We devote all our effort to the development and application of LED products, because the promising market and high potential of LED illumination, meanwhile, offer hi-power LED lamps to you in various specifications to satisfy your needs.
