Researchers at the University of Edinburgh in the United Kingdom conducted a one-year study to determine whether Li-fi could adversely affect the energy efficiency of LEDs. The study was funded by the British Engineering and Natural Science Research Council (EPSRC).
The researchers explained the project in a paper on the effects of visible light communication on lighting and display quality. They found that LEDs can meet the needs of wireless communications and will not affect the light quality or environmental benefits they provide.
Research has shown that LEDs emit digital data at the same time as LEDs, which do not cause the light to change color or darken, or to consume more energy from the LEDs. Maintaining lighting quality is an important consideration because it can have a significant impact on the physical and mental health of people at home and in the workplace.
Wasiu Popoola, chief researcher at the Li-fi Research and Development Center and Digital Communications Institute at the University of Edinburgh, said these were the main concerns of the industry, which prevented consumers from combining LiFi with home led and hindered the widespread use of Li-fi.
With the help of two different data transfer technologies, the researchers studied the creation of warm white light and white led--first is to open key control, during which the LED mode of operation, like Morse code, can quickly switch, the human eye is not easy to detect; second, continuous messaging, period, change the intensity of light to achieve the same goal.
Both techniques were successful and did not significantly reduce the brightness or life expectancy of LED bulbs, nor caused any noticeable change in light color. Both of these technologies only have a slight change in the amount of heat produced by the LEDs. The generation of heat is another important consideration, because rising temperatures mean that LEDs use more power to generate light and reduce energy efficiency.
Dr Popoola added: "Our increasingly networked world needs more bandwidth than is available in the crowded RF portion of the spectrum." Our findings make up for critical knowledge gaps, and our results are very encouraging for future optical communications, which will help realize the full range of economic and social potential of the wireless future. Led manufacturers need to know the impact of joining data transfer capabilities on their products. Our research shows that using LED lights to supplement WiFi has no effect. ”
