solar &wind hybrid street lighting system have prominent advantages of compact design, energy saving and self-powering. In this system, wind turbine are complemented by solar power in supplying power for Led Lamp , as to its hybrid characteristics, which could provide a balance.It's advantages is that if rainy days,cannot use the sun power,then the wind power can work instead.It applies to the place where wind power is strong. Solar Wind Hybrid Street Light Solar Wind Hybrid Street Light,Hybrid Solar Street Light,Wind Solar Street Light Yangzhou Koi Electric Equipment Co., Ltd. , A new type of solar cell dual pixel screen can greatly improve the energy efficiency of mobile phones and e-readers. This technology may also be used in larger displays, such as energy-collecting billboards and decorative solar panels.
Jay Guo, a professor in the Department of Electrical Engineering and Computer Science at the University of Michigan, discovered that a reflective photoelectric color filter device can absorb light and convert it to electrical energy. This study has been published in the NANO magazine sponsored by the American Chemical Society (ACS).
According to Guo, traditional LCD monitors actually have less than 8% of the backlight reaching the viewer's eyes, and the rest are absorbed by color filters and polarizers. "These rays of light are completely wasted," he said. "It's getting hot. If you put your hand close to the monitor, you can feel it. Why don't you try to harvest this energy?"
This is what he did, and his new filter converts 2% of the wasted light into electricity, which can be very effective in a small electronic product.
This new type of filter device is actually a beautiful ultra-thin color filter added to organic semiconductor solar cells, similar to Guo's laboratory research a year ago. The filter is made of metal nano-sheets with precise pitch gratings acting as resonators, capturing and reflecting the light of a particular color, the color relies only on the amount of space between the slits.
The new filter, which is only 200 nanometers thick and 100 times thinner than conventional colorant-based filters, will be even more attractive as a feature of future ultra-thin color displays.
