 Catching the sunlight on the roof, point it in the dark room and vary the color temperature of LEDs. Based on research, conducted at the Georg Simon Ohmhögskolan in Nuremberg takes Osram sunlight lighting one step further. University researchers have developed a sollektor light, which from 900 lenses on the roof of a house leading into the sunlight to the special fittings in the house via fiber. The lenses fit on a surface that is slightly more than half a square meter, which provides light equivalent to 12 60 W incandescent bulbs. On the way to the fixture filtered light from ultraviolet radiation, which damages the skin, and ir-radiation, which warms. The method makes it possible to use between 50 and 70 percent of the incident light to light. Had the sunlight first converted to electricity through photovoltaic cells had only a few percent could be used for lighting, Osram researchers argue. In order to mimic outdoor light fixture with complementary Osram LEDs that add red light morning and evening, and blue light at midday. Sollektorerna only works in direct sunlight. Indirect lighting is not good enough. Therefore, think of Osram they can be used in sunny and warm regions where they are building houses to avoid the heat. With small windows or none at all, will it still be possible to use sunlight to light up indoors. |
