Abstract

The invention provides an illumination method, which comprises the step of using light emitting diode (LED) array display equipment to conduct illumination. When the LED array display equipment is started and light emitted by LED light emitting elements is sensed by light sensing units, the light sensing units transmit light emitting signals corresponding to the LED light emitting elements to a processing unit of the LED array display equipment; the processing unit compares the received light emitting signals with driving control signals indicating whether the corresponding LED light emitting elements should emit light or not and corresponding to the LED light emitting elements; if a comparison result shows that the LED light emitting elements emit light when needing to emit light and do not emit light when needing not to emit light, the LED light emitting elements are judged as working normally; and if a comparison result shows that the LED light emitting elements do not emit light when needing to emit light, and/or emit light when needing not to emit light, the LED light emitting elements are judged as working abnormally. By using the method, the illumination can be conducted effectively.
