OSRAM launches luminous efficiency up to 46 lm/W new performance OLED

After two years of development, OSRAM Opto semiconductor (OSRAM) announced that its warm light OLED efficiency has reached 46 lm/W, the luminosity of 1000cd/m2, continuous use time to reach more than 5000 hours. The company claims that this is the industry's first to improve the efficiency and life of OLED products, in the past as long as the efficiency, service life is shortened, and vice versa.

This achievement is one of the achievements of the OPAL research and Development Association's "500 LM Multi-OLED module" project, the project focuses on the development of small molecules composed of optical layer system, in the form of vacuum evaporation. In addition to OSRAM, SIEMENS R & D technology (Siemens Corporate Technology) is located in Damm and Starr (Darmstadt), Brown Siwik (Braunschweig), Augsburg (Augsburg) and other universities and IPMS Dresden also participate in this project. The OPAL research project is mainly the German Ministry of education and Research (BMBF) initiated, we hope to make joint efforts of all sectors, to enhance the German leadership in the OLED industry, and the research project named OPAL lighting market organic phosphorescent technology application, to build a research platform for the subsequent OLED production and marketing development based on technology. OSRAM plays a coordinating role in the project to develop energy-efficient and efficient OLED light source at the fastest speed.

Photoelectric semiconductor OLED lighting technology department in charge of OSRAM said: "our research and development team in the development of OLED warm light, the key to milepost, efficiency is as high as 46 lm/W (in the integrating sphere to 0.46/0.42 CIE), the service life of more than 5000 hours. Due to the efficiency and service life can be greatly improved, the benefits of OLED flat light can gradually reach the level of traditional lighting solutions, so the scope of application is very extensive.

OSRAM said the plane light source OLED can provide high-quality lighting, lighting decoration, such as for atmosphere and light shade segment. OLED gives off a comfortable light, not only the color can be adjusted individually, it is easier to design an excellent light partition, such as the light can be attached to any surface. In order to be able to be widely used, it is necessary to make a lot of cost-effective OLED, which is another important goal of the project.
