본 발명은 소켓결합구성을 갖는 교류전원 엘이디 조명장치에 관한 것이다.The present invention relates to an AC power LED lighting device having a socket coupling configuration.

상세하게 본 발명은, 교류전원을 입력하여 백열등을 점등시키기 위한 소켓과 결합되는 LED 조명을 구현하여 조명의 적용범위를 확장하고, 컨버터 등의 전용회로구성을 통하지 않고도 간소화된 정류회로와 LED개수의 조절에 의해 교류로 구동하는 엘이디 조명을 구현하여 제품 크기의 소형화 및 제작비용을 절감할 수 있도록 한 소켓결합구성을 갖는 교류전원 엘이디 조명장치에 관한 것이다.In detail, the present invention implements LED lighting coupled with a socket for lighting an incandescent lamp by inputting an AC power source to expand the scope of lighting and simplify the rectification circuit and the number of LEDs without going through a dedicated circuit configuration such as a converter. The present invention relates to an AC power LED lighting device having a socket coupling configuration for realizing LED lighting driven by AC by reducing the size of the product and reducing manufacturing costs.

백열등을 실내조명으로 사용하기 위해서는 필라멘트에 의해 빛을 방출하는 백열전구와, 백열전구가 끼워져 백열전구로 교류전원을 입력하는 소켓의 구성이 요구된다. 이 때, 상기 백열전구는 소켓을 통해 입력되는 교류전원을 전달받기 위해 전극이 나사형태로 형성되며, 상기 나사형태와 대응하여 소켓의 전극도 나사형태로 형성된다.In order to use the incandescent lamp as an indoor lighting, the incandescent lamp that emits light by the filament, and the incandescent lamp is inserted into the socket for inputting the AC power to the incandescent lamp is required. At this time, the incandescent bulb is formed in the form of a screw electrode to receive the AC power input through the socket, the electrode of the socket is also formed in the form of a screw corresponding to the screw.

이와 같은 백열등은 형광등이 출현함에 따라 그 사용빈도가 대폭 감소하기는 하였으나, 백열등의 소켓은 할로겐 램프의 출현에 의해 현재까지도 건축물 내부의 실내조명 구성으로 많이 사용되고 있다.Although incandescent lamps such as fluorescent lamps appear to reduce the frequency of use drastically, the incandescent lamp socket is still used in the interior lighting of the interior of the building by the appearance of halogen lamps.

한편, LED를 이용하여 건축물의 실내공간 조명으로 적용되는 조명장치는 다수의 LED가 실장된 LED 모듈을 특정의 배열로 여러개 배치하고, 상기 LED 모듈을 공간의 천장이나 벽면 등에 설치하여 구성된다. 특히, 상기 LED 모듈은 LED 소자가 적정 전압의 직류전류에 의해 구동하는 특성에 의해 A/D 컨버터를 수반하게 된다.On the other hand, the lighting device applied to the interior space lighting of the building using the LED is configured by arranging a plurality of LED modules mounted with a plurality of LEDs in a specific arrangement, and installing the LED module to the ceiling or wall surface of the space. In particular, the LED module is accompanied by the A / D converter due to the characteristic that the LED element is driven by a direct current of a suitable voltage.

상기와 같은 A/D 컨버터는 교류를 강압하기 위한 트랜스 코일을 포함하게 되며, 이러한 트랜스 코일은 LED 모듈에서 상당한 크기로 배치되기 때문에 이를 적용한 제품이 대형화되는 문제점이 발생된다.The A / D converter as described above includes a transformer coil for stepping down alternating current, and such a transformer coil is disposed at a considerable size in the LED module, which causes a problem in that a product to which it is applied is enlarged.

상기와 같은 문제점을 해결하기 위해 최근에는 SMPS(Switching Mode Power Supply)라 호칭되는 전원공급장치가 적용된다.In order to solve the above problems, a power supply device called a switching mode power supply (SMPS) is recently applied.

참고로, 상기 SMPS는 교류 주파수(50㎐~60㎐)를 직류로 변환하여 높은 주파수로 변경 (수십 ㎑~수백 ㎑)하여 사용하며, 이에 따른 고난도의 기술이 필요하다. 또한, 주파수를 변환 시켜주는 PWM(펄스폭 변조; Pulse width modulation) 방식으로 전원 이용률을 극대화함으로써 고효율과 경제성면에서 기존의 방식에 비해 높은 경쟁력을 겸비하였으며 전원의 안정도가 크게 향상되어졌다.For reference, the SMPS is used by converting an alternating frequency (50 Hz ~ 60 Hz) into a direct current to a high frequency (tens dozens of hundreds ~ hundreds of kHz), according to the technology of high difficulty. In addition, by maximizing the power utilization rate by PWM (Pulse Width Modulation) method that converts frequency, it has high competitiveness and high stability compared to the existing method in terms of efficiency and economic efficiency.

상기와 같은 종래의 백열전구 또는 할로겐 램프가 결합되는 소켓은 교류전원을 입력받기 위한 전용의 구성으로, 백열전구 또는 할로겐 램프 이외의 등기구에는 적용할 수 없기 때문에 조명장치의 사용범위가 제한된다. 특히, 상기 소켓이 설치된 건축물에 LED 조명장치를 설치하기 위해서는 전기시공을 새롭게 해야하는 등의 경제적, 시간적 불이익을 감수해야 하는 문제점이 노출된다.The socket in which the conventional incandescent lamp or the halogen lamp is combined is a dedicated configuration for receiving AC power, and thus the use range of the lighting device is limited because it is not applicable to a luminaire other than the incandescent lamp or the halogen lamp. In particular, in order to install the LED lighting device in the building in which the socket is installed, there is a problem of having to suffer economic and time disadvantages such as having to renew the electric construction.

또한, 상기 LED 조명장치의 전원공급을 위해 적용되는 SMPS는 전술한 장점에도 불구하고, 그 가격이 대단히 비싸기 때문에 단순 조명을 요구하는 LED 모듈에 적용되는 빈도가 대단히 낮다. 동시에, 상기 SMPS 자체도 LED 모듈의 크기에 대비하여 상당히 큰 크기이기 때문에 LED 모듈의 소형화에는 한계가 발생되어 제품 자체를 소형화하기 어려운 문제점이 있다.In addition, the SMPS applied for power supply of the LED lighting device, despite the advantages described above, the price is very expensive, so the frequency applied to the LED module requiring simple lighting is very low. At the same time, since the SMPS itself is also quite large compared to the size of the LED module, there is a problem in miniaturization of the LED module, which makes it difficult to miniaturize the product itself.

본 발명은 상기 문제점을 해결하기 위해 발명한 것이다.The present invention has been invented to solve the above problems.

이에 본 발명은, 상기 소켓과 결합되는 LED 조명을 구현하여 조명의 적용범위의 확장 및 새로운 전기시공에 따른 경제적, 불이익을 해소하고, 간소화된 정류회로와 LED개수의 조절에 의해 교류로 구동하는 엘이디 조명을 구현하여 제품 크기의 소형화 및 제작비용을 절감할 수 있도록 한 엘이디 조명장치를 제공함에 그 목적이 있다.Accordingly, the present invention, by implementing the LED lighting coupled to the socket to solve the economic and disadvantages of the expansion of the scope of illumination and new electrical construction, and the LED driven by alternating the rectification circuit and the number of LEDs simplified The purpose of the present invention is to provide an LED lighting device that can reduce the size and production cost of the product by implementing lighting.

A power supply unit for receiving AC power from the outside; A rectifier for rectifying the input power by a bridge rectifier circuit; The LED driver receives the power rectified by the rectifying unit to drive the LED element, and the LED driver for driving the LED element by a desired voltage by connecting a plurality of LED elements and resistors corresponding to the input power in series. .

이 때, 상기 전원부는 외부에서 정격을 초과하는 과도한 교류전원이 입력되면, 전원입력을 차단하기 위한 퓨즈를 포함하여 구성된다. 또한 본 발명은 PWM 제어를 통해 전류의 입력량을 제어하여 LED 소자의 구동밝기를 조절할 수 있도록 한 컨트롤러를 더 포함하여 구성된다.At this time, the power supply unit is configured to include a fuse for blocking the power input, when the excessive AC power exceeds the rating from the outside. In addition, the present invention is configured to further include a controller to control the driving brightness of the LED device by controlling the input amount of current through the PWM control.

특히, 상기 LED 구동부는 다수의 LED 소자와 저항의 직렬연결된 구성을 1조로 하여 다수조가 병렬연결되어 구성된다.In particular, the LED driving unit is configured by connecting a plurality of pairs in parallel by using a plurality of LED elements and a series connected configuration of resistors.

이상에서와 같이 본 발명은, 백열전구 또는 할로겐 램프가 결합되어 교류전원을 입력하는 소켓에 LED 조명을 적용할 수 있게 되어 소켓에 적용되는 등기구의 사용범위를 확대하며, 소켓의 전기 재시공을 수행하지 않고도 LED 조명을 구현하게 되어 사용자의 경제적, 시간적 이익을 얻도록 한 효과가 있다.As described above, the present invention, the incandescent bulb or halogen lamp is coupled to be able to apply the LED lighting to the socket for input AC power to extend the use range of the luminaire applied to the socket, do not perform electrical reconstruction of the socket LED lighting can be implemented without the economic and time benefit of the user.

또한, 본 발명은 LED 조명을 구현하기 위한 구성에서 트랜스 코일이나 전용의 SMPS 등의 구성이 요구되지 않아 제품을 보다 소형화할 수 있는 효과를 얻게 된다. 뿐만아니라, 본 발명은 보다 간소화된 회로구성에 의해 제작비용이 절감되어 소비자의 제품 만족도를 향상시킬 수 있게 되며, 보다 신속한 제품제작에 의해 생산성을 높일 수 있는 효과가 있다.In addition, the present invention does not require a configuration such as a trans coil or a dedicated SMPS in the configuration for implementing the LED lighting, the effect can be further miniaturized the product. In addition, the present invention can reduce the production cost by a more simplified circuit configuration to improve the customer satisfaction of the product, there is an effect that can increase the productivity by faster production.

상기 전원부(10)는 장치의 구동원이 되는 교류전원(11)을 외부에서 입력받기 위한 구성으로 전술한 나사접속단자부(4)를 포함한다. 이 때, 상기 외부의 교류전원(11)은 본 실시예에서 한국표준으로 사용되는 220V의 전원이며 이에 따라 후술할 LED 구동부(30)의 LED 소자(31) 개수가 지정된다.The power supply unit 10 includes the screw connection terminal 4 described above in order to receive an AC power source 11 that is a driving source of the device from the outside.
