Abstract :
This paper mainly focuses on the calculation of the ROI(Return On Investment) for the LED. First, introduce the basic concept and application of the LED lamp and ROI. Then, decompose the constitution of the maintenance cost into scheduled and unscheduled maintenance. For these two kinds of maintenance, calculate the maintenance time interval separately and the total maintenance cost. Finally, the ROI equation of the LED lamp is obtained. From this, the LED lighting system is inferred from the calculation of the ROI on the LED lamp. Then, make a case study to simulate the ROI in LED light system of different LED scale and make sure the time to begin obtaining merits.
