Osram boosts efficiency of blue LED chips by 8%

Osram Opto Semiconductors GmbH of Regensburg, Germany claims that it has achieved one of the best values in the world in terms of forward voltage for blue high-current chips, leading to an increase in efficiency of up to 8%. Optimized indium gallium nitride (InGaN) chips featuring Osram's UX:3 chip technology are the basis for blue or white LEDs, and are already used in production. The firm also sees considerable potential for reducing forward voltage by a further 20-30mV by the summer, offering a further boost in efficiency.
