Flexible OLED lighting R2 Flex successfully completed in Germany

News from Germany, R2Flex project has been successfully completed. The project aims to develop new technologies, the roll-to-roll (R2R) processing technology is used to make the ​​affordable and efficient and flexible OLED, and finally showed a prototype of a flexible OLED desk lamp.

The flexible OLED panels The project display are made ​​on the metal foil. Why this metal is used because that it is very suitable to do the substrate, but also meet the original intention of the project construction: lower production costs of OLED.

In this project, the main challenge is developing the deposition techniques for the complex structure of the OLED. It is very complex e to execute the process on the roll-to-roll (R2R) manufacturing line, but it still can be successfully completed. What the Tridonic assess this flexible OLED technology includes the safety of the metal substrate and low-cost electrical contact, as well as their lamps integration. Tridonic and Fraunhofer COMEDD together to address the problems caused by the membrane contact.

The organic light emitting layer is only about 200-400 nm thin, located between the two electrodes, the good flexibility makes that it can not be affected when bent, while the color quality is higher than that of the conventional light source.

OLED is an organic LED and also belongs to a class of the LED, with the fiery LED lighting applications,it has gained the growing recognition, LED lighting is surely the main applications of the LED.Nowadays,the LED flood light and LED tube light are the most widely used as the representatives of the decorative lighting  and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED floodlight so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while  low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
