ZigBee-based Smart Environment for LED Light Control

Lighting is one of the most efficient methods to conserve energy. The Philips Research reports that switching from traditional lamps (incandescent and fluorescent lamps) to solidstate lamps using LEDs (LED lamps) has an immediate impact on energy use, CO2 emissions and the environment and it also improves light quality [9]. Therefore, the Philips Research aggressively forecasts that the LED lamps market will grow on average by 45% per year and the size of the market will be $465 billion by 2015. This forecast from the Philips Research clearly indicates that LED lamps will be the future lighting devices for the next generation. Therefore, the PI is expecting that there will be a tremendous amount of market and business opportunities to bring a new level of elegance and reliability to LED illumination. To exploit these tremendous business opportunities, the PI is proposing to improve the elegance and reliability of LED illumination via building a smart environment 1. First, for the proposed smart environment, the PI will implement a low cost and low power ad-hoc wireless sensor network using ZigBee devices [12] . Second, the PI will develop a mobile application that enables people to access the proposed sensor network using smart phones. Finally, to showcase the new level of elegance to LED illumination, the PI will implement a smart application that brings dynamics of daylight inside the working environment by controlling LEDs on the sensor network. To demonstrate the power of the proposed smart environment, the PI placed a video clip of the prototypical implementation on the following YouTube link.
