Description

LED driving device control system {CONTROL SYSTEM FOR LED OPERATION APPARATUS}

The present invention relates to an LED driving device control system.

LEDs have been applied to various electronic applications such as backlights for LCD displays, including personal computers and high-definition TVs, automobile headlights and tail lights, and architectural lighting. Compared to conventional lighting sources such as incandescent lamps and fluorescent lamps, LEDs have many advantages such as high efficiency, good directionality, color stability, high reliability, long life, small size, and environmental safety.

The LED driver functions to supply current to an LED array (string) in which a plurality of LEDs are connected in series. Conventionally, when a failure occurs in one of the LEDs belonging to the LED array, the amount of current supplied to the LED array to which the LED belongs is changed, thereby causing a change in the brightness of all LEDs belonging to the LED array.

Furthermore, conventionally, when a defect occurs in an LED, there is no way to immediately check the defect unless a manager goes to the site and checks it directly. Accordingly, there is a problem in that the LED that does not work is left unattended, and more damage occurs because repair or replacement is not performed in time.

The LED driving device 1020 calculates the magnitude of the voltage applied to the LED in question when a problem occurs in the LED substrate 1050 in which a plurality of LED arrays are installed and one or more LEDs constituting the LED array, and the calculated voltage is In consideration of the size, the LED driver 1060 that prevents load from being generated on the remaining LEDs in the LED board, the communication unit 1080 receiving a control signal for controlling the LED driving device from the server, and the received control signal. Accordingly, a control unit 1070 for controlling the operation of the LED driver and/or a power supply unit 1090 for supplying power to the LED driver and the control unit may be included.

At this time, the LED driver can operate under the control of the controller 1070, and when a problem occurs in one or more LEDs constituting the LED array, a current having the same size as the current flowing through the LED substrate before the problem occurs. By continuing to flow, it is possible to prevent loads from being generated on the LEDs that function normally within the LED substrate. Alternatively, the LED driver controls to flow only as much as the amount of voltage or current allowed for the remaining LEDs based on the magnitude of the voltage or current applied to the LED in which the problem occurs, so that a load does not occur on the normally operating LED. can do.

The upper part of FIG. 2 is a state in which all LEDs of the LED array are emitting light, the middle part is a state in which one of the LEDs of the LED array (LED5) is turned off, and the lower part is a state in which three LEDs (LED5 to 7) of the LED array are turned off Shows the appearance turned off. As described above, when a failure occurs in one or more LEDs in an LED array in which a plurality of LEDs are connected in series, the magnitude of a current applied to another LED of the corresponding LED array or an LED belonging to another LED array may vary. And, accordingly, the brightness of the LED may vary. However, in such a situation, the LED driver 1060 according to an embodiment of the present invention may allow the current flowing before the failure occurs to flow to the corresponding LED array or other LED array without changing its size. Alternatively, the LED driver could allow only voltages and/or currents of an acceptable size to flow through the remaining normally functioning LEDs.

In the LED driver having such a structure, in the active section where energy is supplied from the power supply (24V) side to the LED backlight side, the FET switching element is opened and the voltage is supplied to the LED backlight side through the diode (D2). In the passive section in which energy is not transmitted to the side, the FET switching element is conducted and the voltage is not supplied to the LED backlight side through the diode D2. Therefore, the control method of the output voltage only needs to change the duty rate between the active section and the passive section at a constant switching frequency. As a result, the LED driver can control the output voltage and supply a constant current to the LED backlight. In this case, the LED backlight may mean one or more LED arrays or one or more LEDs.

If there is no response from the administrator's user device, power is continuously supplied to the LED driving device and the LED backlight unit, and the normal operating LED can continue to emit light. Over time, if one or more LEDs of the LED array of the LED substrate fail, the communication unit transmits the failure fact and the location information of the defective LED to the server, and the server transmits this information to the user device. User devices can display this information to the administrator. Even in this case, when there is no response from the manager, power is continuously supplied to the LED driving device, and the normally operated LED of the LED backlight unit continuously emit light. Over time, if a number of LEDs on the LED board are defective, the communication unit transmits to the server the fact that the defect has occurred and the location information of the defective LED, and the server sends this information to the user device, and the user device Presents this information to the manager.
