| Shanghai Widen Photodiode Tech Co.,Ltd is located in the High and New Technology Industrial Development Zone of Minhang,Shanghai.We are the high-tech enterprise who is professional in researching,manufacturing and selling of LED lights and LED display. We have advanced technology of research and development.There are Experts,Doctors,Masters and Senior Engineers for the research of our products.We keep in step with the international advanced technology. And there are a excellent team that engaged in production,installation and service of the LED light,Indoor LED display,Outdoor LED display and related items all the time.Our expert-project team with abundant experience of both large projects and key projects.We are the first-group get through the certifications of ISO9001:2000,CE and ROHS. All aspects operate strictly according to the company quality manual and quality syatem.So the management process become more scientific and specialize the execution system,clear the authority and responsibility,complete the correction and the prevention of the measures.So that we can offer you the best products. For the LED illuminating light,as the first company that manufacture the High Power LED Street light which published more than 100W.Widen Photodiode Co.,Ltd research the outdoor illumination such as LED Street Light(solar,wind energy complementary),LED Tunnel Light, LED Courtyard Light,Landscape Light and so on.We also reseach a series of indoor lights,including LED Mining Light,LED Bulb,LED Tube Light and LED Plane Light.And we attained more tha 20 patent certificates.We are the leader of the High Power Fluorescent Light and Mining Light(30w-300w) at domestic and abroad. Our products are widely used in streets,factories,tunnels,indoor and outdoor lighting,decoration and match with the solar energy and the wind energy facilities,which is the leader of illuminating products over the world.In March 2003, We bagan to research the white semiconductor illumination. Under the entire technical staffs’ efforts. we solved the problem of the heat dissipation of High Power LED Diode (which is a industry bottleneck) by trial and error the semiconductor lighting and heat dissipation of the drive circuit. We can make sure that devices work in the temperature rise about 20 ° C，in terms of the driver circuit,the efficiency of the LED light is more than 93％，the power factor is more than 95％。The Street Light(>100W)and the Mining Light have reached the level of national quality by the detection of the National Electric Light Source Quality and Testing Center. The LED Street Lights and Mining Lights have been used in a number of projects in Shanghai,,Beijing,Hebei,Xinjiang,Jilin and other places. LED illumination has a great and potential market.We not only research the LED illumination but also manufacture different high power lights for the clients according to their requirements.We created “WIDEN” brand for our excellent production,high quality,competitive price and thoughtful service. For the LED Display Screen,our “WASON” Outdoor and Indoor full-color and single-double color LED Display screen is already OK since early 1990s .The full color disply screen stands for high-end and valuableness all the time.Recently, as the developing of the LED chips,the price decrease continuously;,we catch the opportunity and promote a new generation of full color LED display screen which has competitive price with high quality.The user prove that the quality of our full color LED display screen is reliable.Now we have a high, medium and low grade variety of outdoor full-color LED display for the needs of different users. We adopted technology-led, tread the quality as the life of the company and service is more important than anything else. We offer customers high quality products together with timely, thoughtful, excellent service.Our philosophy is ‘qiality honesty,the product can make the customers feel reliable and the service can satisfied with their needs’. During the past years,our company insist develop steady,invest more in management and technology.We expand new market actively and make the performance increase steadily year by year, Now our products cover China.We also export to Japan, South Korea, Brazil and some countries in Europe and America and so on. Our products have been widely applied to various fields: government, telecommunications, electricity, public security, conference rooms, highways, rail transit, tunnels, railways, public utilities, multinational corporations, military, schools, and public media, securities,etc. We will give full play to our characteristics as always, with almost 10 years’ experience, keep the principle ‘customers’ need first, users are the god’, continue to offer service of LED illumination and large display screen display field. |
