Improving LED manufacturing technologies, the company claims new records for the brightness and efficiency of white LEDs in the laboratory. Under standard conditions with an operating current of 350 mA, brightness peaked at a value of 155 lm and efficiency at 136 lm/W. The researchers used white prototype LEDs with 1 mm-square chips. The light produced has a color temperature of 5000K with color coordinates at 0.349/0.393 (cx/cy). Potential applications for this technology include general illumination, the automotive sector, and any application that calls for large, high-power LEDs. These light sources are also suitable for high operating currents, i.e., at 1.4A they can produce up to 500 lm of white light. For more information, call OSRAM OPTO SEMICONDUCTORS, San Jose, CA.
