OLED Achieves 32 Lumens Per Watt

Facebook X LinkedIn Email
MUNICH, Jan. 27, 2012 — Siemens AG announced that its Osram subsidiary has set a new efficiency record, developing a new organic LED (OLED) that generates 32 lumens of light per watt, making it more efficient than a halogen lamp. Osram researchers have now produced in the lab a flexible OLED that emits white light from a surface measuring approximately 11 × 3 cm. The 32-lumens-per-watt device was feasible in part because of a special design for the vacuum-metallized electrical contacts. The record efficiency values were measured using a large-area sample under the most realistic conditions possible, and...Read full article
