본 발명의 실시예의 구성 및 작용에 대하여 첨부한 도면을 참조하여 상세하게 설명한다.The configuration and operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2를 참조하면, 본 실시예에 의한 태양광 발전 조명장치는 태양전지판(100), 지지기둥(200), 엘이디조명부(300), 전원제어부(400)를 포함하여 구성된다.Referring to FIG. 2, the photovoltaic lighting device according to the present embodiment includes a solar panel 100, a support pillar 200, an LED lighting unit 300, and a power control unit 400.

상기 태양전지판(100)은 태양에너지를 이용하여 전기에너지를 생산하는 역할을 하며, Si base, CdTe, Culn2Se 등 다양한 재료를 이용하여 솔라셀(solar cell)을 구성할 수 있다.The solar panel 100 serves to produce electrical energy using solar energy, and may form a solar cell using various materials such as Si base, CdTe, Culn2Se, and the like.

상기 태양전지판(100)은 지지기둥(200)에 의하여 지지된다. 상기 지지기둥(200)은 태양전지판(100)을 지지하는 역할뿐만 아니라, 엘이디조명부(300), 전원제어부(400) 등 각종 부품들을 수용한다.The solar panel 100 is supported by the support pillar 200. The support pillar 200 not only serves to support the solar panel 100, but also accommodates various parts such as an LED lighting unit 300 and a power control unit 400.

상기 지지기둥(200)의 내부에는 전원제어부(400)가 설치되는데, 상기 전원제어부(400)는 태양전지판(100)에서 생산된 전기를 충전함과 동시에 엘이디조명부(300)에 안정적으로 전원을 공급해 주는 역할을 한다.The power supply control unit 400 is installed inside the support pillar 200. The power control unit 400 charges electricity produced by the solar panel 100 and at the same time stably supplies power to the LED lighting unit 300. Role.

도 3을 참조하면, 상기 전원제어부(400)는 대용량콘덴서(410), 충전감지부(420), 제어부(430)를 포함한다.Referring to FIG. 3, the power control unit 400 includes a large capacity capacitor 410, a charge detecting unit 420, and a control unit 430.

본 발명에서는 엘이디조명부(300)에 전원을 공급하여 주는 장치로 대용량콘덴서가 사용된다. 본 발명에서 사용되는 대용량콘덴서는 수백~수천Farad의 용량을 갖는 고용량의 콘덴서이다. 보통 전자회로에 사용되는 콘덴서의 용량은 수백μF 정도이며, 이러한 용량의 콘덴서는 거의 직류전류가 흐를 수가 없으나, 고용량을 가지는 대용량콘덴서는 직류전류가 흐를 수 있어 계속적인 전원을 공급해 줄 수 있다.In the present invention, a large capacity capacitor is used as a device for supplying power to the LED lighting unit 300. The high capacity capacitor used in the present invention is a high capacity capacitor having a capacity of several hundred to several thousand Farad. Capacitors typically used in electronic circuits are about several hundred μF. Capacitors of such capacities can hardly flow direct current, but large capacity capacitors with high capacities can supply DC power continuously.

이러한 대용량콘덴서는 종래의 충전배터리와는 달리 미세한 전압으로도 충전이 가능하고, 수명이 수 백년 정도이므로 반영구적으로 사용이 가능하다.Unlike a conventional rechargeable battery, such a large capacity capacitor can be charged even at a minute voltage, and can be used semi-permanently because its life span is about several hundred years.

하지만, 태양전지의 가장 취약점이 날씨에 따라 태양광이 불규칙하기 때문에 엘이디조명부에 안정적인 전원공급이 어렵다는 것이다. 또한, 대용량콘덴서도 충전된 전기량이 감소함에 따라 엘이디조명부에 공급되는 전압도 감소되는 문제점이 있다.However, the most vulnerable of solar cells is that it is difficult to supply stable power to LED lighting because the sunlight is irregular depending on the weather. In addition, there is a problem that the voltage supplied to the LED lighting unit is also reduced as the amount of electricity charged in the large capacity capacitor decreases.

본 실시예에서는 이러한 문제점을 해결하기 위하여, 충전감지부(420) 및 제어부(430)가 구비된다.In this embodiment, in order to solve this problem, the charge detecting unit 420 and the control unit 430 is provided.

상기 충전감지부(420)는 상기 대용량콘덴서(410)에서 출력되는 전압을 감지하는 역할을 한다. 즉, 충전감지부(420)는 대용량콘덴서(410)의 출력전압이 일정 전압 이상인지 이하인지를 감지하여 그 결과를 제어부(430)에 전송한다.The charge detecting unit 420 detects a voltage output from the large capacity capacitor 410. That is, the charge detecting unit 420 detects whether the output voltage of the large capacity capacitor 410 is greater than or equal to a predetermined voltage and transmits the result to the control unit 430.

도 4를 참조하면, 상기 충전감지부(420)는 제너다이오드(422)를 이용하여 대용량콘덴서의 전압(V)이 일정 전압 이상이면 제너다이오드(422)를 통하여 전류가 흘러 제1스위칭소자(424)가 온 되어 제1라인(423)으로 신호가 입력된다. 한편, 대용량콘덴서의 전압(V)이 일정 전압 미만이면 제너다이오드(422)를 통하여 전류가 흐를 수 없고 이때에는 제2스위칭소자(426)가 온 되어 제2라인(425)으로 신호가 입력된다.Referring to FIG. 4, when the voltage V of the large-capacity capacitor is greater than or equal to a predetermined voltage by using the zener diode 422, a current flows through the zener diode 422 and the first switching device 424. ) Is turned on and a signal is input to the first line 423. On the other hand, if the voltage V of the large capacity capacitor is less than a predetermined voltage, current cannot flow through the zener diode 422, and at this time, the second switching element 426 is turned on and a signal is input to the second line 425.

상기 제어부(430)는 충전감지부(420)에서 전송되는 신호를 입력받아 엘이디조명부(300)로 안정적인 전압을 공급해 주는 역할을 한다.The controller 430 receives a signal transmitted from the charge detector 420 and supplies a stable voltage to the LED lighting unit 300.

예를 들어, 대용량콘덴서의 전압이 15V이고, 제너다이오드의 항복전압을 12V로 하면 제1스위칭소자(424)가 온 되어 제1라인(423)을 통해 제어부로 신호가 입력되고, 상기 제어부는 감압회로를 통해 전압을 적절히 낮춘 후 엘이디조명부(300)에 전압을 인가한다. 한편, 대용량콘덴서의 전압이 12V 이하인 경우에는 제2스위칭소자(426)가 온 되고, 제2라인(425)을 통해 제어부로 신호가 입력되어 제어부는 감압하지 않고 그대로 엘이디조명부(300)에 전압을 인가한다.For example, when the voltage of the large capacity capacitor is 15V and the breakdown voltage of the zener diode is 12V, the first switching element 424 is turned on and a signal is input to the controller through the first line 423, and the controller is depressurized. After the voltage is appropriately lowered through the circuit, a voltage is applied to the LED lighting unit 300. On the other hand, when the voltage of the large capacity capacitor is 12V or less, the second switching element 426 is turned on, and a signal is input to the controller through the second line 425, so that the controller does not decompress the voltage to the LED lighting unit 300 as it is. Is authorized.

따라서, 본 발명에 따르면 대용량콘덴서에 충전이 잘 되는 날씨가 맑고 햇빛이 잘 드는 날과 충전이 잘 되지 않는 날씨가 흐려 햇빛이 잘 안드는 날에 따라 각각 다른 방식으로 제어가 되어 안정적으로 엘이디조명부에 전압을 공급해 줄 수 있다.Therefore, according to the present invention, the capacity of the LED lighting unit is stably controlled according to different methods according to the sunny day when the weather is well charged and the sunny day is not well charged and the day when the sunlight is not well. Can supply

상기 엘이디조명부(300)는 복수 개의 엘이디가 실장되어 빛을 조사하는 장치로서, 엘이디에서 발생되는 열을 외부로 방출하기 위한 냉각부(미도시)을 포함할 수 있다. 또한, 전압의 안정적인 공급을 위하여 정전압 레귤레이터를 추가로 설치할 수 있다. 상기 엘이디조명부(300)의 외주는 커버(310)로 둘러싸여 강한 빛으로 인한 눈부심을 방지한다.The LED lighting unit 300 is a device for mounting a plurality of LEDs to irradiate light, it may include a cooling unit (not shown) for emitting heat generated from the LED to the outside. In addition, a constant voltage regulator may be additionally installed for stable supply of voltage. The outer circumference of the LED lighting unit 300 is surrounded by a cover 310 to prevent glare due to strong light.

본 실시예에서는 태양전지를 예로 하였으나, 상기 태양전지 대신에 풍력발전으로 교체되어도 본 발명이 적용될 수 있다.In the present embodiment, a solar cell is taken as an example, but the present invention can be applied even if the solar cell is replaced with wind power.
