July 22, 2010... Osram Opto Semiconductors (Osram Opto) reports that its developers have increased the efficiency of its red, thin-film LEDs by 30 percent. While most announced improvements in efficiency have been reported about white (from blue with phosphor) LEDs, and blue, the efficiency improvement of red LEDs would seem to bode well for the industry. If the company is able to translate the lab result into a production model red Golden Dragon LED, then applications using a combination of red, blue, and green or red, blue, green, and amber to create white light or using red and cool white to create warm white, will have an improved efficiency overall.

The company says that the improved performance results from improved material properties, further development of the thin-film platform, and greater output efficiency. Osram Opto says that unencapsulated chips benefit even more from the improvements. The boost in efficiency is opening up new LED applications in general illumination, in projection and in the industrial sector, according to the company.
