Description

TECHNICAL FIELD [0001] The present invention relates to an LED lighting device capable of cross-driving through a plurality of power supply units.

The present invention relates to an LED lighting device capable of being cross-driven through a plurality of power supply units, and can extend the service life of a plurality of power supply units by cross-driving a plurality of power supply units according to a set time, A plurality of power supply units having a short life span can be continuously used without replacement of the power supply unit up to the service life of the LED module, To an LED lighting device capable of intersecting driving.

2. Description of the Related Art Generally, an LED lighting apparatus used for lighting purposes is provided with a power supply unit (SMPS) for controlling the intensity of input power to supply power to the LED.

This SMPS means a power supply device in the end of a Switched Mode Power Supply, and uses a switch control method for converting an AC power source to a DC power source by using a transistor or the like.

However, the above power supply device has a short lifetime of 3 to 4 years, and the LED having the power supply device has a useful life of about 10 years, which is longer than the power supply device.

Therefore, the power supply having a short life cycle is required to be replaced several times as compared with the LED during the use of the LED lighting fixture, so that it is troublesome to replace and a maintenance cost is incurred.

In order to solve the above-described problem, it is desirable to extend the lifetime of the power supply unit or to apply the power supply unit to a plurality of the power supply units to match the lifetime of the LEDs. Technology is being developed.

Regarding this technique, Patent Publication No. 10-1169639 discloses an automatic switching power supply in an LED illumination device.

In the technology described above, a plurality of SMPSs that supply power to the LED illumination apparatus are installed, and when the main SMPS abnormality occurs, the power supply of the main SMPS is automatically shut off, and the main SMPS is stopped. To supply power more stably by driving the sub SMPS, and more particularly,

According to claim 1 of the present invention, a plurality of SMPSs are installed in order to supply a stable power to the LED illumination device, and when the main SMPS abnormality occurs, the power supply of the main SMPS is automatically interrupted, The automatic switching power supply apparatus includes first and second resistors R1 and R2 connected to an output terminal JP1 of the main SMPS, One end of the relay coil L1 in the relay RY1 is connected and the connection point of the third and sixth resistors R3 and R6 is connected to the relay coil L1 via the voltage detector Q1 and the switching element Q2. And a relay output terminal JP2 connected to the relay contacts 3 to 8 which are interrupted according to whether the relay RY1 is driven or not and the input and output terminals JP3 and JP4 of the sub SMPS Quot ;, and " It describes a circuit configuration of a power supply to enable the automatic switching of the device.

However, the above circuit configuration of the power supply unit is provided with a condition of 'abnormal occurrence'. If the SMPS is not used for 3 to 4 years, which is the normal lifetime of the SMPS, Devices are not used, and thus the device which is not used for a long period of time is not used, so that the life of the electrolytic capacitor, which is a core part, is degraded and the function is lost.

Next, there is a problem that the life of the lead used for assembling the device may be degraded and the function may be lost.

Next, in applying a plurality of power supply apparatuses, it is not clear that the order in which these power supply apparatuses are operated is determined.

Finally, despite the above studies, one of the drawbacks of the prior art is that there are no additional functions that can be achieved in applying multiple power supplies.

As an example, even if a plurality of power supply units are applied, a function element for operation to a power supply unit positioned in the following order is required by reliably determining when a failure occurs in the power supply unit.

For example, if a plurality of power supply units are sequentially cross-driven, and the algorithm is clarified, it is possible to control the heat generated on the circuits provided in the respective power supply units, Despite the fact that the service life can be prolonged, there is no such provision in the above-described technique.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents And variations are possible.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

The present invention relates to an LED lighting device capable of being cross-driven through a plurality of power supply units, and can extend the service life of a plurality of power supply units by cross-driving a plurality of power supply units according to a set time, A plurality of power supply units having a short life span can be continuously used without replacement of the power supply unit up to the service life of the LED module, To an LED lighting device capable of intersecting driving.

1 and 2 of the accompanying drawings, an LED lighting device capable of cross-driving through a plurality of power supply units according to the present invention will be described.

FIG. 1 is a schematic view illustrating an LED lighting device capable of cross-driving through a plurality of power supply units according to the present invention.

1 of the accompanying drawings may mainly include a control unit 10, a switch 20, a power supply unit 30, and an output sensing unit 40. [

At this time, a plurality of switches 20 and power supply units 30 are connected to one control unit 10, and the other end may be connected to one LED module.

Hereinafter, each of the plurality of switches 20 and the power supply unit 30 is divided into one line, two lines, three lines, ... n lines. In the n line, n means n > 1, each division is referred to as a line, and what is referred to as a stage means a position in the line.

That is, the meaning of the stage can be interpreted that the power supply unit 30 is located at the next stage of the switch 20. [

At this time, the plurality of switches 20 are provided as many as the number of the power supply units 30, and the number of the power supply units 30 is preferably three to four, but the present invention is not limited thereto and may vary depending on design conditions .

The reason that the power supply unit 30 is composed of three to four is because the lifetime of the power supply unit 30 is 3 to 4 years, So that the supply part 30 is not to be replaced.

In the present invention, the time for delivering power to the power supply unit 30 is set, and the power is supplied to the power supply unit 30 for a preset time period. And transmits power to the other power supply unit 30 when the set time is exceeded.

The control unit 10 may include a timer module 11, a time setting module 12, a power supply control module 13, a reset determination module 14, and a comparison module 15.

The timer module 11 counts the time and counts the number of times that the time set by the time setting module 12, which will be described later, exceeds the line to which power is to be applied.

The time setting module 12 performs a function of setting and storing a time for applying power to one power supply unit 30 and may provide an interface for time setting according to design conditions.

At this time, the interface for setting the time may be provided in a touch type, a button type, or the like which is not shown in the figure but can operate the time setting through a separate device or a display means provided externally.

That is, the timer module 11 counts the time set by the time setting module 12.

The power supply control module 13 controls the power supply unit 30 to supply power to the power supply unit 30 for a predetermined period of time.

The time set here may be, for example, 1000 hours, but is not limited thereto and can be variously applied.

That is, when power is applied to the power supply unit 30 of one line and the set time (1000 hours) is exceeded, the power is supplied to the power supply unit 30 of the two lines. When the set time (1000 hours) Power is supplied to the power supply unit 30 of the line.

When the power is applied to the last n lines and the set time (1000 hours) is exceeded, the power can be applied again to one line.

To this end, the power supply control module 13 can turn on the switch 20 provided in the power supply part 30 of the line to which the power is to be applied. In addition, in the power supply part 30, The switch 20 can be turned off.

The switch 20 is connected to the next stage of the control unit 10 so that the power supply unit 30 is connected to the next stage of the switch 20 and the LED module is connected to the next stage of the power supply unit 30. [ do.

The output sensing unit 40 may be connected to the next stage of the power supply unit 30. The output sensing unit 40 performs a function of sensing a power output from the power supply unit 30. [

That is, in the above description, the power is supplied to the power supply unit 30 according to the control of the control unit 10, and when the set time is exceeded, the power is supplied to the power supply unit 30 of the next line. The power supply control module 13 of the control unit 10 controls the power supply unit 30 so that when the power supply unit 30 detects that the corresponding power supply unit 30 does not output power due to a failure of the power supply unit 30, It is possible to operate except the line provided with the power supply unit 30 according to the control of the control unit 30.

For example, if the power supply unit 30 of one line outputs a signal indicating the failure from the output detection unit 40 connected to one line, the control unit 10 operates according to the set time as described above, When the time set by the power supply unit 30 is exceeded, the power is supplied to the power supply unit 30 of two lines.

This is also true in the case of other lines (2, 3, ..., n lines), and in another example, when a failure occurs in all lines, (E.g., a fault line determination module, a notification module, etc.), so that the user can be informed of the failure of all the lines.

As another example, the control unit 10 may control to apply a small amount of power to the faulty line side, which may be performed through the power supply control module 13 or a separate configuration (not shown) A second power supply control module, an auxiliary power supply control module, etc.).

The reason why a small amount of power is applied to the broken line side as described above is that the failure of the power supply unit 30 or the like may be temporary rather than permanent. If the fault is a temporary error, Not doing so is because of maintenance problems.

Accordingly, when a small amount of power is supplied to the failed line and it is sensed that the power is supplied from the power supply unit 30 in the output sensing unit 40 connected to the line, the control unit 10 controls the failure line determination module or the power supply control module The control unit 13 recognizes that the corresponding line is operated and controls the line to be included in the operation sequence according to the set time.

This can be operated in the same manner even when there are a plurality of broken lines. It should be understood that the small amount of power is the minimum amount of power that the power supply unit 30 can supply and output power.

Of course, the small amount of power described above is not necessarily limited to a minimum amount, but it may be desirable to apply a minimum amount of power to prevent unnecessary consumption of power.

Accordingly, the LED illumination device capable of crossing the plurality of power supply units according to the present invention is not used until the life of one of the power supply units 30 is reached, but is controlled by the control unit 10, It is possible to control the heat on the circuit that is generated during use so that the reduction in durability due to excessive heat can be reduced and consequently the service life of the power supply unit 30 can be prolonged.

Therefore, it may be desirable that the set time described above is adopted at such a time that the generated heat is not excessively generated.

On the other hand, if the time for the use of the line is initialized and the set time is again used in the re-On operation of the LED module, the power supply unit 30 ).

Hereinafter, the present invention will be described.

The reset determination module 14 determines whether the LED module is turned on again after the LED module is turned off. The reset determination module 14 may include a last operating line determination unit and a last operating line time detection unit.

This will be described with reference to FIG. 2 of the accompanying drawings.

FIG. 2 is a block diagram illustrating a configuration of a reset determination module in an LED lighting device capable of cross-driving through a plurality of power supply units according to the present invention.

The final operation line determination unit functions to determine a line that was last operated before the operation is turned off when the LED module is turned On again.

For example, the last operating line can be determined based on the number of times that the timer module 11 has been counted based on the operation of the timer module 11.

The last operation line time detection unit 12 detects the time when the last operation line is judged by the last operation line judgment unit and the power was applied to the last operation line.

This can detect the time at which the power was applied to the last operating line by determining the time set by the time setting module 12 and the time counted by the timer module 11. [

The comparison module 15 compares the time when the power was applied to the last operation line detected by the last operation line time detection unit of the reset determination module 14 and the time set by the time setting module 12 .

Then, the power supply control module 13 can control to apply power to the corresponding final operation line only by the time difference compared by the comparison module 15. [

According to the design conditions, the comparison module 15, when the time difference of the comparison result is equal to or less than the set value, loses information on the difference of the compared time and then transmits a signal indicating that there is no information compared to the power application control module 13 .

In this case, the power application control module 13 can control the switch 20 so that power is supplied to the power supply unit 30 located on the next line of the determined final operation line.

The value set at this time means a value with respect to the time set in the time setting module, and may be 10% with respect to the time. However, the% gauge described above is not necessarily limited to 10%, and can be variously applied according to design conditions.

However, if the time is set to 1000 hours, the time detected by the last operating line time detecting unit is set to 950 hours, If the difference is 100 hours, it corresponds to 5% for the set time.

That is, when the set value is 10%, 5% is less than 10%, and the comparison module 15 loses information about the difference. Then, the power supply control module 13 sends a signal to the power supply control module 13 that there is no information to be compared, and the power supply control module 13 applies power to the power supply unit 30 located on the next line.

According to the present invention configured as described above, the LED lighting apparatus capable of intersecting driving through the plurality of power supply units described above can extend the service life of the plurality of power supply units by cross-driving the plurality of power supply units according to the set time And a plurality of power supply units having a relatively short life span as compared with the LED module are provided, so that there is an advantage that the life of the LED module can be continuously used without replacement of the power supply unit.

Therefore, the present invention has an advantage that it is possible to reduce the inconvenience of maintenance and costs incurred.

1 and 2 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 and 2 It is self-evident.
