| Outline of Final Research Achievements |
Japan faced huge power shortage problems and was forced to execute scheduled blackouts because of Tohoku Earthquake that happened on March 11, 2011. It raised people’s motivations to save the electric power. The power saving problem has been recognized as one of the most important initiatives since days.
In this study, we developed a lighting system that can automatically dim the lights according to the brightness of the surrounding area in order to achieve an efficient power saving. All LED light bulbs can autonomously transmit and receive the brightness data through a network based on visible light communications(VLC). We developed an application on Web browser and can watch the previous saving records and the current power saving situation in each room. On the other hand, we can control the brightness of the lamps in each room from a remote place by sending a command to the cloud server. In addition, the pinpoint dimming is realized by VLC between a LED lamp and a smart phone.
