OSRAM 104 lm/W luminous efficiency LED prototype developed successfully in the laboratory

A high luminous efficiency, good color, a comfortable warm white light LED prototype, now OSRAM Opto Semiconductor Laboratory successfully developed. The LED set of ordinary lighting source of the three important features in one: 3000K color temperature, color rendering index of 82, and the luminous efficiency of 104 lm/W.

The LED warm white light and comfortable, from advanced conversion technology, not only the light generated by the excellent quality and efficiency is even more impressive. Because the warm white light is mainly for home lighting applications, so the combination of these features makes LED can be widely used in the field of general lighting. Up to now, only 100 lm/W or more luminous efficiency can be achieved in the cold white spectrum. OSRAM Opto Semiconductors in Germany headquarters responsible for warm white LED R & D Project Manager Dr. Frank Baumann said: "excellent light quality and excellent energy efficiency will enable the successful combination of LED technology to achieve commercial breakthrough earlier. High luminous efficiency, comfortable and pleasant new light source is no longer just a dream. "

Color temperature is 3000 K, light color and LED halogen lamp is similar to that of chromaticity coordinates falls in the track of Planck (Planckian curve), belongs to the pure white, no migration to green spectral region. The new chip LED prototype chip area is only 1 mm2, the 350mA operating current can be achieved at a brightness of 124 LM, equivalent to the luminous efficiency of 104 lm/W.

These record results, thanks to OSRAM to provide professional and technical aspects of the new chip architecture, packaging and epitaxial process improvement, improve efficiency and combined converter. OSRAM will gradually introduce new technologies in production. On OSRAM Opto Semiconductors OSRAM SIEMENS industrial sector subsidiary, is also one of the two largest lamp manufacturers in the world, its subsidiary OSRAM Opto Semiconductors GmbH (Germany Regensburg) provide semiconductor technology lighting, sensor and visualization applications solutions for its customers.
