Patent ID: 8421644

Claim:
A light-emitting diode (LED) control system, comprising: a physical LED; a storage device; at least one processor; and one or more computerized codes stored in the storage device and executable by the at least one processor, the one or more computerized codes comprising: a setting module operable to set a number of virtual LEDs to indicate a number of error events, assign a priority level to each error event and a unique indication status of the error event, wherein each virtual LED is represented by a graph that is displayed on a display device of the LED control system; a detection module operable to detect one or more error events occurring to the LED control system according to preset conditions; and a command module operable to control a virtual LED to display a corresponding indication status of each error event, direct the physical LED to synchronously display an indication status of an error event having the highest priority level, if more than one error event exists at the same time; wherein, when the error event having the highest priority level quits, if other error events remain, the command module is further operable to direct the physical LED to synchronously display an indication status of an error event that has the highest priority level in the remain error events; and when the physical LED is displaying a current indication status of a current error event, if a new error event having a higher priority level occurs, the command module is further operable to change the indication status of the physical LED from the current indication status to an indication status of the new error event having the higher priority level.
