Solid state lighting popular high power LED into the main

Since high power LED will become the next generation of solid-state lighting (SSL) of the main, the electronics industry has emerged more bold new thinking. That is, to abandon the congestion of radio frequency bandwidth, the speed of the human eye is difficult to identify the LED switching mode to transmit data, this approach is called LED visible light communication (VLC). Through advanced technical support, each new LED lamp can be wired to connect the backbone network, so that the wireless communication between different devices can be achieved, and will not increase the burden of the existing RF bandwidth.

This kind of LED visible light communication transmission technology uses the white light LED, because the white light LED characteristic is the fast response, can act as the visible light communication technology foundation. LED visible light transmission technology is the use of fluorescent light or white light LED and other indoor lighting equipment, the naked eye can not detect the high speed light and shade signals, wireless transmission of data. Because of the wide wavelength range, the visible light can be transmitted through different wavelengths through the design. The R & D personnel will also test the different wavelengths of light, the use of different colors constitute a white light, the development of multiple data streams encoded content.

The advantages of LED visible light communication technology, in general can avoid electromagnetic wave WLAN or high frequency wireless transmission, interference effects on the human body and the surrounding electronic equipment, and can replace the wireless base station, and has the characteristics of high safety. At present, many industries, standards organizations, or government funded programs have begun to develop LED visible light communication, its prospects are very promising. After all, only the size of the traditional lighting market will reach several trillion dollars, the future transition to solid state lighting market, its business is very impressive. StrategiesUnlimited company predicts that this year, the LED lighting market will exceed $1 billion in 2014 is expected to grow to $7 billion 300 million.
