Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a control device capable of reducing power consumption and pattern control of an LED lamp,

The present invention relates to a control device capable of power saving and pattern control of an LED luminaire which enables economical installation and efficient operation while controlling various driving patterns such as blinking or brightness of an LED luminaire for each time period.

From the use of the flame generated by burning wood, oil, etc. as a light source of illumination, electric lamps are now being used as a light source in everyday life. Such a luminaire is an indispensable tool not only in everyday life but also in human economic activity because it increases the time for human activity.

In order to use the luminaire effectively, it is required to be able to easily control on off (hereinafter referred to as "blink"), and furthermore, a technique of controlling the brightness is required. Currently, the luminaire using electricity has made all of the above-mentioned control possible, and various convenience and usefulness necessary for living have been added. In addition, a light emitting diode (LED) having a bright illumination function is proposed as a light source technology of a luminaire while a power consumption is small, and the function of the luminaire has been variously developed in the industrial field as well as everyday life.

However, humans were not satisfied with the simple flickering and brightness and economical efficiency of the LED luminaire, and required the technology to control the flicker and brightness of the luminaire more efficiently and variously automatically. Accordingly, a dimming technique capable of easily adjusting the blinking and brightness of an LED luminaire according to the situation of the field or the time zone has been developed.

However, such conventional dimming technology has been limited in the application to a public luminaire (hereinafter, referred to as a 'public luminaire') that is controlled by a specific agency such as a streetlight or a security lamp by a wireless controller or a timer controller. Furthermore, since the public lighting system must control the blinking at the precise time at the designated facility every designated time, it is inevitably limited to control the blinking or brightness differently for each luminaire in the same area.

However, since the public luminaire can be installed in the cultivation area or the area where the residents appeal to the light pollution, and the public luminaire installed in this area is also controlled to be flicker-like as in the case of the public luminaire installed in other areas of the same area, There was a problem that there were few inconveniences of the crops and the residents.

In order to solve such a problem, conventionally, a control device for controlling only the public lamp installed in the uncomfortable area has been developed. However, since the conventional control device has to be installed in only one public lamp or a plurality of public lamps having the same blinking time, it is cumbersome and inconvenient to remotely control them individually. Further, when a plurality of LED modules are configured in one public lamp, a plurality of conventional control devices must be divided to control each of the LED modules, and a plurality of switched mode power supplies (SMPS) there was. Of course, such a problem is not easy to solve due to the characteristics of a narrow public luminaire such as a street lamp or a security lamp, and there is a problem that the appearance is never desirable.

As a result, there has been a problem in that the public luminaire itself is not installed at all in the inconvenient area, the above-mentioned maintenance difficulty and the economical burden due to the installation are incurred, and the conventional control device is unreasonably installed.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an LED lighting device capable of performing power control and pattern control of an LED luminaire that can easily and economically and efficiently control the blinking control of an LED lamp such as a street light or a security lamp using an LED luminaire. And to provide a control device.

According to an aspect of the present invention,

A power module for inverting electricity received from the SMPS;

A plurality of relays for switching each of the electricity distributed in parallel from the power module;

An LED module for blinking the LED according to switching of the relay; And

A control module for switching the relays according to a flash pattern for each time period set for each relay;

Which is a control device capable of power saving and pattern control of an LED lamp.

The present invention described above can control the LED modules even when a single SMPS supplies power for driving a plurality of LED modules and can be applied to existing LED lamps and controls the blinking of LED modules in various patterns There is an effect that can be done.

Through this, it is possible to solve the problem that the existing installation is caused by the light pollution and crop damage, and it is effective to reduce the budget for installing the public lighting fixture.

The present invention is capable of various modifications and various forms, and specific embodiments are illustrated in the drawings and described in detail in the text. It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a configuration of a control device according to the present invention, and FIG. 2 is a block diagram showing a configuration of a control module configured in the control device.

The control device according to the present invention controls the power supply 200 while being operated under the control of the SMPS 100 for transforming and rectifying the AC power received, the power supply module 200 for receiving the power from the SMPS 100, and the control module 500, LED modules 410, 420, and 430 that are turned on and off according to the switching of the relay unit 300 and the operation of the relay unit 300 And a control module 500 for controlling the LED module units 410, 420, and 430 by controlling them.

The SMPS 100 is an abbreviation of SWITCHED MODE POWER SUPPLY, and functions as a power supply device. As is well known, the SMPS 100 uses a switch control method for converting an AC power source to a DC power source using a switching transistor or the like. As described above, since the SMPS 100 is a well-known technology, the operation method, structure, and principle of the SMPS 100 will not be described here.

The power module 200 converts the DC power received from the SMPS 100 into the electricity required for the operation of the control module 500 and the LED modules 410, 420, and 430, and supplies the converted electricity. In general, there is a difference between the magnitude of the electric voltage and current required for the operation of the control module 500 and the magnitude of the electric voltage and current required for lighting the LED module units 410, 420 and 430, Electric power of different sizes may be required for lighting the LED module 1 410, the LED module 2 420 and the LED module 3 430 constituted in the LED modules 410, 420 and 430, Electricity of different sizes may be supplied to each of the module 1 410, the LED module 2 420, and the LED module 3 430. To this end, the power module 200 inverts the electricity received from the SMPS 100. Since the inverting function, which is a function of the power module 200, utilizes a publicly known inverter, the detailed description of the power module 200 and the description of the description will be omitted here.

The relay unit 300 switches the energization between the LED module units 410, 420, and 430 and the power module 200. In this embodiment, the LED module 1 410, the LED module 2 420, and the LED module 3 430, which are three LED modules, are configured in the LED module units 410, 420, and 430, The relay unit 300 of the embodiment includes a relay 1 310, a relay 2 320, and a relay 3 330. As a result, the relay 1 310 switches the LED module 1 410, the relay 2 320 switches the LED module 2 420, and the relay 3 330 switches the LED module 3 430.

The LED module units 410, 420, and 430 control the application of electric power to the LEDs to blink the LEDs. The LED module units 410, 420, and 430 are publicly known LED devices, which will be described in detail.

The control module 500 controls the LED module 1 410, the LED module 2 420 and the LED module 3 430 blinking through the relay unit 300 individually in the LED module units 410, And furthermore, the SMPS 100 can be used to drive a plurality of LED modules. Also, the control module 500 can make the blinking time of the LED module 1 410, the LED module 2 420, and the LED module 3 430 different according to the set blink pattern.

The control module 500 for this purpose will be described in more detail.

The control module 500 includes a CPU 510 operating according to a set process, an RTC 520 checking time, an input / output unit 530 for setting an adjustment pattern of the relay unit 300, a CPU 510 A transmission / reception unit 550 for allowing the CPU to communicate with the outside for adjustment of the LED module units 410, 420, and 430; And a failure detection unit 570 for checking whether the control device is in failure by checking the power distribution state and the switching state of the control device.

The CPU 510 controls the relay unit 300 according to the set process. As described above, the relay unit 300 controls the blinking of the LED module units 410, 420 and 430, so the process set in the CPU 510 controls blinking of the LED module units 410, 420 and 430 . The CPU 510 checks the time at the RTC 520 and transmits an ON signal or an OFF signal to the designated relay unit 300 at the time of the process. Of course, the module receiving the signal from the LED module units 410, 420, and 430 turns on or off so that the LED module units 410, 420, and 430 are turned on or off.

The RTC 520 is an abbreviation of a real-time clock. When the time is set by the program, the RTC 520 causes an interrupt to recognize the CPU 510. Of course, the CPU 510 transmits the ON signal or the OFF signal in accordance with the interrupt of the RTC 520, as described above. Since the configuration circuit and operation of the RTC 520 are known and common technologies, the description thereof will be omitted here.

The input / output unit 530 adjusts the set time of the RTC 520 in response to the operation of the operator in order to control the blink patterns of the LED module units 410, 420, and 430. As described above, since the RTC 520 is programmed for time setting, the operator can input the program output and set values using the input / output unit 530. [ (Not shown) for connecting the portable computer so that the program of the RTC 520 can be updated using a portable computer such as a laptop.

The dip switch 540 is a DIP switch formed on the circuit board of the CPU 510 so that the operator can adjust the circuit board function of the CPU 510 without changing the hardware of the CPU 510. [

The transmission / reception unit 550 allows the control device to be directly controlled from a long distance. The control device according to the present invention is for controlling the blinking of a public lamp such as a street lamp or a security lamp, and a public office for managing a public lamp must manage a large number of LED module units 410, 420, and 430. However, since the LED module units 410, 420, and 430 of the public luminaire are dispersed and installed in a vast area, it is difficult to visit the site one by one. Therefore, in order to collectively manage all of the LED module units 410, 420, and 430 in one place, the control unit constitutes a transmitting / receiving unit 550 having a communication function. The transmission / reception unit 550 is connected to the CPU 510 or the RTC 520 so that the operator adjusts the CPU 510 or the RTC 520 at a remote location.

The GPS unit 560 confirms the position of the control device and transmits the confirmed GPS information to the remote worker through the transmission / reception unit 550. [ In addition, an operator who visits the site can confirm the control unit by checking the GPS unit 560 of the control unit.

The fault detection unit 570 checks whether the control device is faulty, a distribution fault problem, and so on, and alerts or adjusts the fault. A more detailed description of this is given below.

FIG. 3 is a block diagram showing a configuration of a first safety module and a second safety module according to the present invention. Referring to FIG.

The control device according to the present invention includes a first safety module 700 for confirming a power distribution state and a second safety module 600 for correcting a power distribution error.

The control device according to the present invention provides a relatively complicated wiring structure because the control module 500 controls the blinking of a plurality of LED modules. Of course, there is a possibility that the power distribution for the blinking of the LED module is also error-prone.

Therefore, the control device according to the present invention can constitute a safety device for preventing power distribution error, and constitutes a double safety device in this embodiment.

The first safety module 700 includes current sensors A1, A2, and A3 configured between the relay unit 300 and the LED module units 410, 420, and 430. The current sensors A1, A2, and A3 detect the energization to each wire in real time and transmit the detection result to the control module 500. [ The control module 500 switches the energization to the corresponding LED module units 410, 420 and 430 by controlling the relay unit 300 as described above, When the power distribution is confirmed, the control module 500 opens the relays 310, 320, and 330 of the relay unit 300 to stop the distribution to the LED module units 410, 420, and 430.

The second safety module (600) monitors the power distribution abnormality identified by the first safety module (700) and switches the power distribution so that the power distribution for lighting is performed.

FIG. 4 is an enlarged view of a configuration of the second safety module, and FIG. 5 is a view illustrating a power distribution of the second safety module. Referring to FIG.

The LED module units 410, 420 and 430 may include the LED module 1 410, the LED module 2 420 and the LED module 3 430, . The LED module 1 410 is wired to the relay 1 310 through the first line L1 and the LED module 2 420 is wired to the relay 2 320 via the second line L2 , And the LED module 3 (430) is wired through the third line (330) and the third line (L3).

The first line L1 includes an eleventh wiring line L11 for wiring the LED module 1 410 and a twelfth wiring line L12 for wiring the second line L2, And a thirteenth wiring line L13 for wiring the third line L3. The second line L2 includes a twenty-second wiring line L21 which includes the twenty-second wiring line L22 for wiring with the LED module 2 420 and is connected to the first line L1, And a twenty-third wiring line L23 for wiring the third line L3. The third line L3 includes a thirty-first wiring line L31 including the thirty-third wiring line L33 for wiring with the LED module 3 430 and the first line L1, 2 line L2 and a 32nd wiring line L32 for wiring.

Subsequently, a first changeover switch 610 for switching the distribution of the eleventh wiring line L11, the twelfth wiring line 12 and the thirteenth wiring line 13, a twenty-second wiring line L22 and a twenty- A second switching switch 620 for switching the distribution of the wiring line 21 and the 23rd wiring line 23 and a third wiring line L33 for connecting the 31st wiring line 31 and the 32st wiring line 32, And a third change-over switch 630 for switching the distribution of the power supply. Accordingly, power distribution to each wiring line can be switched through switching of the first, second, and third changeover switches 610, 620, and 630.

A more detailed description thereof will be described with reference to the drawings.

As shown in FIG. 5 (a), when all the LED modules are turned off under the control of the control module 500, no power is supplied to each wiring line.

The control module 500 closes the relay 1 310 and the relay 3 330 to turn on the first line L1 of the LED module 1 410 and the relay 3 330 when the LED module 1 410 and the LED module 3 430 turn on, And the third line (L3) of the LED module 3 (430). 5 (b), power is supplied to the second line L2 other than the first line L1 due to the error, and the power supply confirmation signal of the first safety module 700 is supplied to the control module The CPU 510 controls the second changeover switch 620 of the second safety module 600 according to the set process. The second changeover switch 620 switches the second energizing switch 621 to the twenty-first wiring line L21 under the control of the CPU 510 so that the electric power supplied to the second line L2 is supplied to the twenty- (L21) to the LED module 1 (410). Meanwhile, since the third line L3 for lighting the LED module 3 430 is normally supplied, the third changeover switch 630 supplies the third energizing switch 631 to the designated thirty-third wiring line L33 Lt; / RTI >

The LED module 1 410 should be turned on and the control module 500 closes the relay 1 310 so that the first line L1 of the LED module 410 is energized. As shown in FIG. 5 (c), when the first switch L1 is not energized and the second line L2 is energized due to an error, the first changeover switch 610 is turned off , The CPU 510 controls the second changeover switch 620 of the second safety module 600 according to the set process. The second changeover switch 620 switches the second energizing switch 621 to the twenty-first wiring line L21 under the control of the CPU 510 so that the electric power supplied to the second line L2 is supplied to the twenty- (L21) to the LED module 1 (410).

As a result, even if electricity is not applied to the LED module specified by the error, the LED module designated by the correction of the second safety module 600 is normally turned on or off. Of course, the error information is transmitted to the remote worker via the transmission / reception unit 550, so that error of the control device can be repaired.

6 is a view showing an operation of the power distribution switch configured in the second safety module.

The following embodiments may be presented for rapid power distribution switching among the wiring lines in the first, second and third changeover switches 610, 620 and 630 according to the present invention (hereinafter referred to as 'first changeover switch 610').

The first changeover switch 610 includes the energizing switches 611, 621 and 631 (hereinafter referred to as '611'), rotation motors 616, 626 and 636 (hereinafter referred to as '616') for rotating the energizing switch 611, The wiring line terminals 612 to 614, 622 to 624 and 632 to 634 (hereinafter, referred to as '612 to 614') connected to the wiring lines and detachably connected to the energizing switch 611, 615, 625, 635 (hereinafter, '615').

Therefore, when the wiring line terminals 612 to 614 of the wiring line to be distributed under the control of the CPU 510 project and the rotation motor 616 rotates, the energizing switch 611 contact with the protruding wiring line terminals 612 to 614 and electric power is applied to the corresponding wiring line.

For reference, the wiring line terminals 612 to 614 are arranged along the circumference of the rotation of the energizing switch 611 by the number of wiring lines corresponding to the number of the LED modules, and the energizing switch 611 rotating at the center While maintaining contact with the wiring line terminals 612 to 614 and applying electricity to the corresponding wiring line terminals 612 to 614. The wiring line terminals 612 to 614 are connected to the terminal blocks 612a to 614a under the control of the CPU 510 and terminal blocks 613a and 6112a to 614a which are inserted into the turning radius of the energizing switch 611, And solenoids 612b through 614b for releasing the solenoids.

5, when the LED module is turned off, the rotation motor 616 is in a stopped state under the control of the CPU 510. Therefore, As shown in the figure, the energizing switch 611 is disposed downward by its own weight.

5 (b), if the energizing switch 621 of the second changeover switch 620 is to be wired with the twenty-first wiring line L21, the second changeover switch 620 is turned to the 21st The connection terminal 622 connected to the wiring line L21 projects the terminal block 622a. Further, the rotation motor 626 rotates the energizing switch 621 to make contact with the terminal block 622a.

The third changeover switch 630 is connected to the terminal block 632a of the connection terminal 634 connected to the 33rd wiring line by the third changeover switch 630, .

Subsequently, as shown in FIG. 5 (c), in the situation where energization to the eleventh wiring line L11 has to be performed, the connection terminals 612, 613, and 614 are disconnected due to the failure of the first changeover switch 610, The corresponding connection terminal 621 of the second changeover switch 620 to which electricity is applied causes the terminal block 622a to protrude and the rotation motor 626 to turn the energizing switch 621 are rotated to come into contact with the terminal block 622a.

On the other hand, since the third changeover switch 630 does not receive the operation signal, the operation of the connection terminals 632, 633, 634 and the rotation motor 636 is stopped.
