Cause Bo reporter at Fudan University School of Information Science and Engineering Laboratory to experience this is called "LiFi" (LightFidelity) new technology. Under a 1 watt LED small light irradiation, laptops, he is showing cartoons, when a reporter with the palm to block the light, cartoon show stopped, the reporter also hand down and out in the light, cartoon occasionally stuck ...... Could this light can work around computers? The answer is: a computer to play the video, and computer access is in the mystery of this LED lamp light. In fact, on the day before yesterday, Fudan University researchers will "Light Internet" offline highest refresh rate to 3.7G, real-time system average access speeds of up to 150M, a world record. Next month, 10 prototype will be unveiled in 2013 Shanghai International Industry Fair. Millions of times per second flicker pass information yesterday, the reporter went to Fudan University School of Information Science and Engineering Laboratory laboratory, field experience the "light line" of the entire process. Reporters saw two LED lamp beads are respectively mounted on the transmitter and receiver and is connected to a laptop. Reporter palm block LED light, it really is playing on a laptop cartoon network interrupted when reporters away palm, animation and continue playing. Professor of Fudan School of Information Science and Engineering, said Chi Nan solar lights direct factory in Zhengzhou, the mystery in which a special transmission, the receiving device. "Light and radio waves, all belong to an electromagnetic wave, the basic principles of propagation network signal is the same." Research by the emitter current of the LED in the balance converted into communication current to control it millions of times per second flashing light indicating 1, off behalf of 0. In this way, LED bulbs can quickly transmit binary encoding. Thus, the computer will be able to "read" in the light implicit "Password" Zhengzhou solar street prices, and "Light the Internet." Bo tells cause LED Ceiling Installation Notes (1) When installing ceiling lights in masonry structure should be used embedded bolts or expansion bolts, nylon plugs or plastic plugs fixed; not use wedge. And the carrying capacity of the stationary member should match the ceiling light in weight phase. Ceiling fixed firmly to ensure reliable Zhengzhou solar lights, and extend its life. (2) When using expansion bolts, should be the choice of technical requirements bolt specifications, the hole diameter and laying depth to match the bolt specifications. (3) Number of fixing the lamp holder fixing bolt should not be less than the number of holes on the lamp base and bolt diameter should be matched with the aperture; no fixed mounting holes on the base of the lamp (when installing self-drilling) Zhengzhou solar street lights manufacturer, Each fixture for fixing the bolts or screws not less than 2, and the center of gravity and the center of gravity of the lamp to coincide with the bolt or screw; only when the insulating units in 75mm diameter and below, before using a bolt or screws. (4) Ceiling not directly mounted on flammable objects, some families for aesthetic lining behind the plywood ceiling lamps with paint after the fact, this is very dangerous, insulation measures must be taken; if the lamp surface temperature near the site When the fuel, but also to take the heat or cooling measures. (5) should also be checked before installation Ceiling: ① lead section of each fixture wire line core, Tongxin soft line is not less than 0.4 mm2 copper core of not less than 0.5 mm2, or lead must be replaced. ② wire and lamp connection between the lamp connected in parallel to a solid lead, should be good electrical contact, in order to avoid due to poor contact, sparking occurs between the wire and the terminal, and dangerous.
