Whether Li-Fi has effects on LED lighting quality? The foreign research result is this......

Researchers at the University of Edinburgh conducted a one-year study, to determine whether Li-Fi will adversely affect the energy efficiency of LED. This study was supported by the engineering and Physical Sciences Research Council (EPSRC) funded.

The researchers explained the project in the "research" on the lighting and display quality of visible light communication. They found that LED can meet the demand for wireless communication, will not affect the quality or provide environmental benefits.

Research shows that the transmission of digital data in LED light at the same time, LED does not make the light or dark color, it will make LED more energy consumption. To maintain the quality of lighting is a very important consideration, because it can be in the home and workplace people's physical and mental health have a significant impact.

University of Edinburgh Li-Fi R & D center and digital communication research institute chief researcher Dr Popoola Wasiu said, these are the major concerns of the industry, these problems hinder the consumers will be used in conjunction with LiFi home LED, also hindered the widespread adoption of Li-Fi.

In two different data transmission technology, the researchers have warm white and cold white light LED-- is the first key control period, the working mode of LED with the Morse code, you can quickly switch the human eye is not easy to detect; second, during the continuous communication, change the light intensity to achieve. The same goal.

These two techniques are very successful, did not significantly reduce the brightness of the LED lamp or life expectancy, also did not cause any obvious color change. These two techniques are only on the heat generated by the LED have slight change. Heat generation is another important consideration, because temperature rise means that LED will use more power to produce light, reducing its energy efficiency.

Dr. Popoola added: "we are increasingly networked world needs more bandwidth, more bandwidth than the RF spectrum in the crowded can provide. Our results for the key knowledge gaps for optical communications in the future, our results are very inspiring, this will help to achieve the full economic and social potential future wireless. LED manufacturers need to know the effect of adding data transmission capabilities for its products. Our study shows that the use of LED lamps to supplement WiFi and no effect."
