About Us 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 sale 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 lamps, LED courtyard lamps, landscape lamps, and LED wall lamps of the outdoor illumination and LED bulbs, and LED daylight lamps 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) leading in the industry and are widely used in the city lightening, illumination in road and tunnel, outdoor and indoor illumination, decoration, and also fit in the sun and wind energy driven system. We have launched the R&D of semiconductor white illumination since March, 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 degrees centigrade and both the efficiency and power factor of driven circuit in LED lights will reach 90% and 93% respectively. Moreover the LED street lamp with qualified economization and illumination has passed the quality detection of National Light Testing Center and Light Testing Center of Fudang University. Our LED street lamps worked in many projects held in Beijing, the Provinces of Hebe, Xinjiang, and Jilin and have been sold in Occident and Southeast Asia. We are devoted all our effort to the development and application of LED products, because the promising market and high potential of LED illumination. Meanwhile, we offer hi-power LED lamps to you in various specifications to satisfy your needs. Then we will forge the Dayi brand in the market by our excellent production process, reasonable price and highly qualified products.
