48V
Lfp Battery applies more to hi-power electrical scooter, electric
three-wheeler, electrical car, and residential & commercial power storage
that perfectly matches the 48V off-grid DC/AC inverter. Li-phosphate battery is
more tolerant to full charged conditions and is less stressed than other li-ion
storage if kept at high voltage for a prolonged time period under the
monitoring of a battery management system.

Dr. Karsten Heuser, Head of O LED Lighting Technology at OSRAM Opto Semiconductors, is very pleased with the results achieved in the mid-term of research and development. He said: "The efficacy of the new product reaches 46 lumens / watt (CIE measured on the integrating sphere is 0.46/0.42) With a service life of more than 5,000 hours, our development team has created a real milestone in the history of warm white OLED development. With the improvement of light efficiency and longevity, OLED planar light sources are getting closer to the level of traditional lighting solutions, and will surely Wide range of applications."
The prototype of a product of about 100 square meters has a color rendering index (CRI) of 80. It is expected that by March 2009, the development project is expected to achieve a major breakthrough. The energy-saving OLED planar light module (demo version) composed of multiple illuminating panels will achieve a total luminous flux of up to 500 lumens, while the power consumption does not exceed 10 watts. 
Laboratory records of light-emitting diodes. Organic light-emitting diode lighting (ie, O-LED lighting) achieves a luminous efficacy of 46 lumens per watt, brightness of up to 1,000 cd/m2, and a lifespan of more than 5,000 hours, enabling the first simultaneous enhancement of two key features of OLEDs. In the past, light efficiency and longevity have been the same: light efficiency is improved, life is shortened, and vice versa.
