1. A flame retardant lamp, comprising:
a lamp body;
a printed circuit board (PCB);
a power supply;
a light-emitting plate;
a controller;
a driving circuit; and
a first temperature sensor;
wherein the PCB, the power supply, and the light-emitting plate are disposed inside the lamp body, the controller and the driving circuit are disposed on the PCB, and the first temperature sensor is disposed on the light-emitting plate;
the controller is electrically connected to the light-emitting plate through the driving circuit, the first temperature sensor is electrically connected to an input end of the controller, and the power supply is electrically connected to a power supply end of the PCB;
the controller is configured to execute a computer program stored therein to execute following steps:
obtaining a temperature value of the light-emitting plate through the first temperature sensor at every preset time period;
comparing a first temperature value of the light-emitting plate at a first current moment with a second temperature value of the light-emitting plate at a first last moment, and generating a first comparison result; and
when determining that a light-transmitting surface of the lamp body is covered according to the first comparison result, controlling the driving circuit to stop driving, and then turning off the light-emitting plate.
