State information monitoring method, device and system of LED lamp

The invention discloses a state information monitoring method of an LED lamp. The state information monitoring method comprises the steps of acquiring product parameter information of the LED lamp andfailure decision information of each hierarchical part of the LED lamp, and monitoring the obtained target information of each hierarchical part; building a failure physical model of each hierarchical part of the LED lamp according to the product parameter information; acquiring fault state information of the LED lamp according to the failure decision information, the target information and eachfailure physical model; and monitoring remaining life state information of the LED lamp according to the target information and each failure physical model. The invention discloses a state informationmonitoring device and system of the LED lamp. The target information of different hierarchical parts of the LED lamp is acquired in real time, the failure physical model is employed, the fault stateinformation and the remaining lifetime state information of the LED lamp are acquired according to the failure decision information and the target information of each hierarchical part, thus, the monitoring of a fault state and a remaining lifetime state can be more accurately achieved, and running and maintenance of the LED lamp are facilitated.
