Description
본 발명은 자동차 공조패널용 공조장치에 관한 것으로, 특히 종래의 전구에 비하여 10여배의 수명을 가지는 EL패널을 사용한 자동차 공조패널용 공조장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning panel for an automobile air conditioning panel, and more particularly, to an air conditioning panel for an automotive air conditioning panel using an EL panel having a lifespan of about ten times as compared to a conventional light bulb.
자동차에는 야간운전시 공조패널의 시인성과 조작의 용이성을 확보하기 위하여 공조패널용 조명장치가 설치된다.The vehicle is equipped with an air conditioning panel lighting device to ensure visibility of the air conditioning panel and ease of operation during night driving.
종래의 자동차 공조패널용 조명장치는 소정 위치에 전구들을 부착하고, 상기 전구들에서 발광되는 빛을 산란부재를 통하여 주위로 분산시켜서 공조패널일정한 조명을 가져오는 구조로 되어있다.The conventional lighting device for a vehicle air conditioner panel attaches light bulbs to a predetermined position, and distributes light emitted from the light bulbs to the surroundings through a scattering member to produce a uniform air conditioning panel.
이러한 종래의 공조패널의 분해사시도가 도 1에 도시되어 있다.An exploded perspective view of such a conventional air conditioning panel is shown in FIG. 1.
도시된 바와 같이 전구(10)들이 PCB기판(20)상에 부착되어 있고, 상기 전구(10)들에서 발산되는 빛을 전면패널로 유도하기 위한 투명부재(30)로 이루어져 있었다.As shown in the drawing, the bulbs 10 are attached to the PCB substrate 20 and made of a transparent member 30 for guiding light emitted from the bulbs 10 to the front panel.
그런데, 이러한 종래의 공조패널의 경우 자동차의 수명보다 현저히 짧은 수명을 가지고 있어서, 자동차의 사용중 잦은 교체를 요하는 단점이 있었다. 또한 점광원인 전구를 통하여 빛을 균일하게 전달하는데 문제가 있었다.However, such a conventional air conditioning panel has a significantly shorter lifespan than the life of an automobile, and thus has a disadvantage of requiring frequent replacement during use of the automobile. In addition, there is a problem in uniformly transmitting the light through the light bulb as a point light source.
본 발명은 일렉트로루미네선스(electroluminescence : 형광체 분말로 구성된 발광층에 교류전압을 가하면 형광체내에 전자가 가속되어 고에너지 전자가 발생하여 이에 의해 발광되는 현상)패널(이하 EL패널)을 사용하여, 자동차의 공조패널을 조명하는 자동차용 공조패널 조명장치를 제공함에 그 목적이 있다.According to the present invention, an electroluminescence (electroluminescence) phenomenon is applied to a light emitting layer made of phosphor powder, and electrons are accelerated in the phosphor to generate high energy electrons, thereby emitting light. It is an object of the present invention to provide a vehicle air conditioning panel lighting device for illuminating the air conditioning panel.
본 발명의 또 다른 목적은 인버터의 출력 주파수를 변화함으로써 공조패널 조명의 색을 변화시킬수 있는 자동차용 공조패널 조명장치를 제공함에 있다.Still another object of the present invention is to provide an automotive air conditioner panel lighting apparatus capable of changing the color of the air conditioning panel light by changing the output frequency of the inverter.
본 발명 자동차 공조패널용 조명장치는, 인버터의 출력에 따라 빛을 발하는 EL패널과 상기 EL패널을 작동하기 위한 인버터로써 달성된다.The lighting device for a vehicle air conditioner panel of the present invention is achieved as an EL panel which emits light in accordance with the output of the inverter and an inverter for operating the EL panel.
상기 인버터는 공조패널 내부의 PCB기판상에 설치되며, 주파수의 변환이 가능함이 바람직하다.The inverter is installed on the PCB substrate inside the air conditioning panel, it is preferable that the frequency can be converted.
이하 첨부된 도면들에 의거하여 본 발명 자동차 공조패널용 조명장치의 바람직한 실시예를 상세하게 설명한다.Hereinafter, a preferred embodiment of the lighting device for a vehicle air conditioning panel according to the present invention will be described in detail with reference to the accompanying drawings.
첨부 도면 중 도 2는 본 발명 자동차 공조패널용 조명장치의 사시도이다.Figure 2 of the accompanying drawings is a perspective view of a lighting device for a vehicle air conditioning panel of the present invention.
도시된 바와 같이 자동차용 공조패널(100)의 전면패널(110)에는 공조장치를 조절하기 위한 스위치(120)들이 부착되어있고, 공조장치의 상태를 나타내는 표식(112)(일반적으로 공조패널의 문자와 표식들은 빛을 투과할수 있는 투명 아크릴 소재등으로 제작되어 있어서 후면에서 발하는 빛이 통과한다.)들이 구비되어있다.As shown in the front panel 110 of the automotive air conditioning panel 100, the switch 120 for adjusting the air conditioning apparatus is attached, and the mark 112 (in general, the letters of the air conditioning panel) indicating the state of the air conditioning apparatus And markers are made of transparent acrylic material that can transmit light.
이러한 표식(112)들은 그 후면의 조명장치에서 발산된 빛을 투과할수 있도록 되어있다.These markers 112 are adapted to transmit light emitted from the lighting device at the rear thereof.
첨부 도면 중 도 3은 본 발명 자동차 공조패널용 조명장치의 구성도이다.3 of the accompanying drawings is a block diagram of a lighting device for a vehicle air conditioning panel of the present invention.
도시된 바와 같이, 공조패널의 PCB기판(150)상에는 EL패널(200)의 구동을 위한 전원을 공급하는 인버터(152)가 구비되어 있는데, 직류 전원이 PCB기판(150)으로부터 공급되면 인버터(152)에서 상기 직류 전원을 EL패널(200)을 구동하기에 적합한 교류전원으로 변화하여 공급하게 된다.As shown, an inverter 152 is provided on the PCB board 150 of the air conditioning panel to supply power for driving the EL panel 200. When the DC power is supplied from the PCB board 150, the inverter 152 is provided. In this case, the DC power supply is changed into an AC power supply suitable for driving the EL panel 200.
상기 인버터(152)에서 공급되는 교류 전원은 제어부(300)의 조절에 의하여 그 전원의 주파수가 변환됨이 바람직하다.AC power supplied from the inverter 152 is preferably the frequency of the power is converted by the control of the control unit 300.
이렇게 EL패널(200)에 전원이 공급되면 EL패널(200)에서는 빛이 발산되고, 발산된 빛은 투명부재(130)를 통하여 유도되어 전면패널의 표식(112)들과 스위치들을 조명하게된다.본 발명에 적용된 EL패널은 100V, 50 Hz에서 10럭스의 조명도를 갖는 디스플레이를 적용하며, 인버터의 출력 주파수를 변화함으로써 공조패널 조명의 색을 변화시킬수 있다.When power is supplied to the EL panel 200, light is emitted from the EL panel 200, and the emitted light is guided through the transparent member 130 to illuminate the marks 112 and the switches of the front panel. The EL panel applied to the present invention applies a display having an illumination degree of 10 lux at 100 V and 50 Hz, and can change the color of the air conditioning panel light by changing the output frequency of the inverter.
첨부 도면 중 도 4는 본 발명 자동차 공조패널용 조명장치의 분해사시도이다.4 is an exploded perspective view of a lighting device for a vehicle air conditioning panel of the present invention.
EL패널(200)은 전면패널(110)의 후면에 위치하게 되는데, 도시된 바와 같이 점 광원이 아니고 면광원이기 때문에 투명부재(130)의 형상이 단순하고, 균일한 빛으로 전면패널(110)의 표식(112)를 조명 할 수 있게 된다. 종래에는 점 광원인 전구로부터 발산되는 빛을 균일하게 분산하기 위하여 투명부재가 그 후면이 경사지게 형성되는등의 복잡한 형상으로 이루어져 있었다.The EL panel 200 is located at the rear of the front panel 110. Since the front panel 110 is not a point light source but a surface light source as shown, the shape of the transparent member 130 is simple and uniform. The marker 112 can be illuminated. Conventionally, in order to uniformly disperse light emitted from a light bulb which is a point light source, the transparent member has a complicated shape such that its rear surface is inclined.
그 작동을 간략하게 설명하면, 인버터(152)에서 상기 EL패널(200)에 전원이 공급되면 형광체내의 전자가 가속되어 고에너지 전자가 발생하여 발광하게 되는데, 이렇게 발광된 빛이 전면패널(110)의 후면에 부착되어 있는 투명부재(130)들에 의하여 유도되어 전면패널(110)의 표식(112)들과 스위치들(120)을 균일하게 조명하게 된다. Briefly describing the operation, when power is supplied from the inverter 152 to the EL panel 200, electrons in the phosphor are accelerated to generate high energy electrons to emit light. Guided by the transparent members 130 attached to the rear of the front panel 110 to uniformly illuminate the markers 112 and the switch 120.
본 발명 자동차 공조패널용 조명장치는 조명수단으로 종래의 전구보다 수명이 10배 이상 긴 EL패널을 사용함으로 인해서 잦은 전구의 교체의 불편함을 해소 하였고, 또한, 그 조명의 밝기와 색상의 조절이 가능하고, 패널 전체가 균일하게 조명되는 효과가 있다.The lighting device for a vehicle air conditioner panel of the present invention eliminates the inconvenience of frequent replacement of a bulb by using an EL panel that is 10 times longer than a conventional bulb as a lighting means, and also controls brightness and color of the lighting. It is possible to achieve the effect that the entire panel is uniformly illuminated.
