Panasonic has developed a new high efficiency LED lighting technology

Matsushita Electric (Panasonic) with high efficiency LED lighting technology and the key to the company's exclusive brightness index sense of "Feu", the most ideal configuration design space, which can reach 30% of the energy saving effect, low cost so as to introduce energy-saving LED lighting and reduce carbon dioxide emissions to take into account. This is one of the results of Matsushita and Osaka cooperation environment, global warming countermeasures project. Matsushita Electric Company in order to improve the energy saving effect of LED lighting, developed a "a white light blue LED cut through the phosphor after the loss" and "cut power losses" related key technology. According to the main heat loss loss of red and green fluorescence powder related "(reducing the efficiency of phosphor temperature rise caused)," rear scattering loss "(because of the light blocking or absorption leads to directional light irradiation surface can not be effectively removed) two, reduced to about half of the original, about 80% of the fluorescent powder the conversion efficiency was increased by about 90%. At the same time, the company also developed a high frequency drive and a new way to make the power supply can be miniaturized (about half of the original), the power supply circuit components conversion efficiency of about 90%, the loss is reduced to about 1/3. Only in terms of lamps, with the company's highest efficiency LED lighting (LED150 type Downlight), energy efficiency increased by about 10%. In addition, in order to make LED lighting in the lighting space real comfortable and effective configuration, the company used "Feu" for field test in some of the facilities of Osaka, to accumulate numerous lighting data, brightness required by measuring the sense of space, get a lot of LED lighting simulation test data. The results show that the flexible application of LED unique light distribution characteristics, coupled with the wall of light distribution, with the most about 20% of the power saving, reducing the number of LED lighting, can maintain the same sense of brightness.
