A new manufacturing technology is expected to greatly reduce the cost of light-emitting diodes (LEDs) in the future. For the first time ever, researchers at the Siemens subsidiary Osram Opto Semiconductors were able to successfully produce gallium nitride LED chips on a silicon substrate instead ...

Under the direction of Prof. Dr. Holger Heuermann of the University of Applied Sciences Aachen a scientific consortium developed an energy-saving bulb free of electrodes and quicksilver. From September 2016 on it will be impossible for consumers to buy any traditional bulbs. They need to switch ...
