이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 조명장치의 내부구성을 나타낸 블럭도로, 도시된 바와 같이, 조명장치는 ON/OFF, 색상변환, 밝기조절, 타이머 설정 등의 기능조작을 위한 다수의 버튼(노브)으로 이루어진 조작부(10)와, 상기 조작부(10)의 작동에 따라 해당 기능을 수행하기 위한 제어신호를 출력하는 제어부(20)와, 조명장치의 구동에 필요한 전원을 공급하는 전원부(30)를 구비한다.1 is a block diagram showing the internal configuration of a lighting apparatus according to the present invention, as shown, the lighting apparatus is a plurality of buttons (knobs) for the operation of ON / OFF, color conversion, brightness adjustment, timer setting, etc. And a control unit 20 for outputting a control signal for performing a function according to the operation of the operation unit 10, and a power supply unit 30 for supplying power for driving the lighting device. .

또한, 본 고안의 전원장치는 빛을 발하는 발광부(50)를 구비하는데, 상기 발광부(50)는 도 2에 도시된 것처럼 기판(51)에 장착된 적색, 녹색, 청색의 3원색 발광다이오드(LED1,LED2,LED3)로 구성되며, 그 외부는 빛을 난반사시켜 혼합하는 투명 파유리, 투명 아크릴, 투명 크리스탈 소재의 난반사판(60)이 감싸고 있다.In addition, the power supply device of the present invention includes a light emitting unit 50 for emitting light, the light emitting unit 50 is a red, green, blue three primary color light emitting diode mounted on the substrate 51 as shown in FIG. It is composed of (LED1, LED2, LED3), the outside is surrounded by a diffuse reflection plate 60 of transparent cullet, transparent acrylic, transparent crystal material mixed by reflecting light.

아울러, 본 고안의 전원장치에는 상기 발광부(50)를 구동시키는 LED 구동부(40)가 구비되는데, 상기 LED 구동부(40)는 제어부(20)의 제어신호에 따라 발광다이오드 (LED1,LED2,LED3)를 점소등시켜 조명장치를 ON/OFF시키거나, 특정 발광다이오드(LED1,LED2,LED3)를 점등 및 소등시킴으로써 조명장치의 색상을 변환시킨다.In addition, the power supply device of the present invention is provided with an LED driver 40 for driving the light emitting unit 50, the LED driver 40 is a light emitting diode (LED1, LED2, LED3) in accordance with the control signal of the control unit 20 ) To turn on / off the lighting device or to turn on / off specific light emitting diodes (LED1, LED2, LED3) to change the color of the lighting device.

또한, 상기 LED 구동부(40)가 제어부(20)의 제어신호에 따라 각 발광다이오드 (LED1,LED2,LED3)에서 발산되는 빛의 강도를 상이하게 조절하도록 구성한다면더욱 다양한 색상을 발현할 수 있다.In addition, if the LED driver 40 is configured to differently control the intensity of the light emitted from each of the light emitting diodes (LED1, LED2, LED3) according to the control signal of the control unit 20 can be more various colors.

다음에는 상기와 같이 구성된 본 고안에 따른 조명장치의 동작방법을 상세히 설명하기로 한다.Next, the operation method of the lighting apparatus according to the present invention configured as described above will be described in detail.

사용자가 조명장치를 ON시키기 위하여 조작부(10)의 특정 버튼을 조작하면, 제어부(20)는 버튼 조작에 따라 조명장치를 ON시키기 위한 제어신호를 LED 구동부(40)로 출력한다. 이에 따라 LED 구동부(40)는 기 설정된 발광다이오드, 예를 들어 적색, 녹색, 청색 발광다이오드(LED1,LED2,LED3)를 모두 점등시킨다.When the user operates a specific button of the operation unit 10 to turn on the lighting device, the control unit 20 outputs a control signal for turning on the lighting device to the LED driver 40 according to the button operation. Accordingly, the LED driver 40 turns on all of the preset light emitting diodes, for example, the red, green, and blue light emitting diodes LED1, LED2, and LED3.

따라서, 적색, 녹색, 청색 발광다이오드(LED1,LED2,LED3)에서 발산된 빛이 난반사판(60)에 부딪혀 난반사 되면서 혼합됨에 따라 조명장치는 무색의 빛을 발하게 된다. 이때, 제어부(20)는 발광부(50)의 발광다이오드(LED1,LED2,LED3)가 기 설정된 강도로 빛을 발하도록 제어한다.Therefore, as the light emitted from the red, green, and blue light emitting diodes LED1, LED2, and LED3 hits the diffuse reflection plate 60 and is diffusely reflected, the lighting device emits colorless light. In this case, the controller 20 controls the light emitting diodes LED1, LED2, and LED3 of the light emitting unit 50 to emit light at a predetermined intensity.

이와 같이 조명장치가 점등된 상태에서 사용자가 빛의 색상을 가변하기 위하여 조작부(10)의 특정 버튼을 조작하면, 제어부(20)는 점등된 발광다이오드(LED1,LED2, LED3)중 어느 하나 또는 두개의 발광다이오드를 OFF시킨다. 예를 들어, 청색 발광다이오드가 소등되고 적색과 녹색 발광다이오드가 점등되면 조명장치는 황색의 빛을 발하게 되며, 또는 일정한 순서에 따라 예컨대 적색 청색 녹색의 순서로 점등이 반복되던가 한다. 다시 말해, 점등된 적색, 녹색, 청색 발광다이오드(LED1,LED2,LED3)에서 발산되는 3원색의 조합에 따라 조명장치(스텐트 또는 간판 등의 Back light 등등)에서 발하는 빛의 색상이 가변되고, 그 발광순서도 조절하도록 허여된다.When the user operates a specific button of the operation unit 10 to change the color of the light while the lighting device is turned on as described above, the control unit 20 controls any one or two of the light emitting diodes LED1, LED2, and LED3. Turn off the LED. For example, when the blue light emitting diode is turned off and the red and green light emitting diodes are turned on, the lighting device emits yellow light, or the lighting is repeated in the order of red blue green according to a certain order. In other words, the color of light emitted from an illumination device (a back light such as a stent or a signboard) varies according to a combination of three primary colors emitted from lit red, green, and blue light emitting diodes (LED1, LED2, LED3). The order of emission is also allowed.

한편, 제어부(20)가 버튼 조작에 따라 각 발광다이오드(LED1,LED2,LED3)로 인가되는 전류의 크기를 조정하여 각 발광다이오드(LED1,LED2,LED3)에서 발산되는 빛의 강도를 상이하게 조절한다면 적색, 녹색, 청색 발광다이오드(LED1,LED2,LED3)에서 발산되는 3원색의 조합에 따라 더욱 다양한 색상의 빛을 발현할 수 있다.On the other hand, the control unit 20 adjusts the intensity of the light emitted from each light emitting diode (LED1, LED2, LED3) by adjusting the amount of current applied to each light emitting diode (LED1, LED2, LED3) according to the button operation. If it is a combination of the three primary colors emitted from the red, green, and blue light emitting diodes (LED1, LED2, LED3) it can express a variety of colors.

도 3은 본 고안이 적용된 조명기구의 일 예(스텐드에 적용)를 나타낸 도면이다. 전구의 형태로 정형화된 광원이 아닌 소형의 발광다이오드를 광원으로 사용함에 따라, 도시된 바와 같이, 제품의 디자인을 자유롭게 설계할 수 있음을 알 수 있다. 따라서, 학습용 스탠드, 실내외 인테리어 조명, 광고판넬의 백라이트(Back Light), 무드 스탠드 등에 본 고안을 다양하게 적용할 수 있다.Figure 3 is a view showing an example (applied to the stand) of the luminaire to which the present invention is applied. By using a small light emitting diode as a light source instead of a light source shaped in the form of a light bulb, it can be seen that the design of the product can be freely designed as shown. Therefore, the present invention can be variously applied to a learning stand, indoor and outdoor interior lighting, a back panel of an advertising panel, a mood stand, and the like.

상기와 같이 본 고안은 적색, 녹색, 청색의 3원색 발광다이오드를 광원으로 사용함에 따라 각 발광다이오드에서 발산되는 빛을 혼합함으로써, 다양한 색상의 빛을 발현할 수 있으며, 전력소비도 기존의 백열등이나 형광등에 비해 약 1/3 이하로 절감할 수 있다.As described above, the present invention uses red, green, and blue three-color light emitting diodes as light sources, thereby mixing light emitted from each light emitting diode to express various colors of light. Compared to fluorescent lamps, it can be reduced to about one third or less.

또한, 자외선을 발생하지 않음에 따라 전시품의 탈색을 방지할 수 있으며, 10만 시간 이상을 사용할 수 있는 내구성을 가지고 있어 기존의 백열등이나 형광등을 사용하는 조명장치에 비해 유지, 관리에 필요한 비용을 절감할 수 있다.In addition, it prevents discoloration of exhibits by not generating ultraviolet rays, and has a durability that can be used for more than 100,000 hours, thus reducing the cost of maintenance and management compared to lighting devices using incandescent or fluorescent lamps. can do.

아울러, 소형의 발광다이오드를 광원으로 사용함에 따라 자유로운 제품 디자인 설계가 가능하며, 발열량도 적어 화상의 위험도 제거할 수 있다.In addition, by using a small light emitting diode as a light source, it is possible to design a product design freely, and the amount of heat generated is also reduced, thereby eliminating the risk of burns.

본 고안은 도면에 도시된 일실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에 통상의 지식을 지닌 자라면 이로부터 다양한 변형 및 균등한 타실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 고안의 진정한 기술적 보호범위는 첨부된 특허청구범위에 의해서만 정해져야할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
