Abstract:
1. A light emitting diode (LED) illuminating system, comprising: a LED illuminating circuitry comprising a plurality of LEDs connected in a matrix; an actuator connected to the LED circuitry to actuate the plurality of LEDs, the actuator comprising a sensor; and a control circuitry comprising a controller, and the controller is connected to the actuator, wherein the sensor is configured to detect an output signal of the actuator and output a detected data value to the controller; the controller is configured to compare the detected data value with a predetermined data value stored in the controller, and outputs a scan signal to the actuator when a LED is determined to be malfunctioning; the actuator is configured to scan each LED and to output a location parameter of the malfunctioning LED to the controller based on the scan signal.
