ＬＥＤ 등기구 ＯＮ／ＯＦＦ를 통한 디밍 제어 시스템{LED Lighting ON/OFF Dimming Control System}     Dimming control system through LED luminaires ON / OFF

본 발명은 등기구 제어장치에 관한 것으로, 보다 상세하게는 등기구내 2개 이상의 SMPS의 ON/OFF 제어만으로 디밍 시스템을 구축하고 LED Module의 불량을 검출하는 컨트롤러를 통해 추가 불량 방지를 제어하는 장치에 관한 것이다.
The present invention relates to a luminaire control device, and more particularly, to an apparatus for controlling a further failure prevention through a controller for establishing a dimming system only by ON / OFF control of two or more SMPS in the luminaire and detecting a failure of an LED module. will be.

근래 저탄소 녹색성장이 각광을 받으며 기존 종래조명을 대체하는 광원으로 LED조명의 수요가 늘고 있다. LED 조명은 단순한 ON/OFF의 기능만 있는 다수의 종래 조명과는 달리 조도, 색온도를 조절하고 리모콘 및 여러 가지 센서를 적용하는 다양한 어플리케이션을 가지고 있다. LED조명은 일반적으로 SMPS(Switching Mode Power Supply)를 이용하여 LED를 구동하며 LED는 전류제어 소자로서 정전류 방식의 회로를 사용한다. 정전류 방식은 SMPS에 LED Module에 일정한 전류를 공급하는 방식으로 SMPS내 소자 및 LED 수량을 이용하여 전류값을 셋팅하고 SMPS 전원 공급 시 LED Module의 전류값을 Feedback하여 일정한 전류를 공급하도록 제어 한다. 일반적으로 LED 조명 SMPS는 Flyback 방식의 회로를 많이 적용하고 있다. Flyback방식은 효율이 높고 단가가 저렴하지만 출력이 낮은 특성이 있어 고와트 LED 조명제품에서는 2개 이상의 저와트 SMPS를 사용하거나 고와트용 방식의 SMPS를 사용한다.Recently, low-carbon green growth is in the spotlight, and the demand for LED lighting is increasing as a light source that replaces existing conventional lighting. Unlike many conventional lights that have only ON / OFF functions, LED lighting has a variety of applications that adjust illumination, color temperature, and apply remote controls and sensors. LED lighting generally uses a switching mode power supply (SMPS) to drive the LED, and the LED uses a constant current circuit as a current control device. The constant current method is to supply a constant current to the LED module to the SMPS. It sets the current value using the number of devices and LEDs in the SMPS and controls to supply a constant current by feeding back the current value of the LED module when SMPS power is supplied. In general, the LED lighting SMPS has a large number of flyback circuits. Flyback method has high efficiency and low cost but low output, so high watt LED lighting products use two or more low watt SMPS or high watt SMPS.

본 발명은 2개 이상의 절연타입 SMPS를 사용하는 제품에 해당되며 별도의 디밍회로가 없이 디밍을 구현하여 심플하면서 LED의 수명을 일정하게 유지한다. 또, 보호회로를 통해 LED Module을 보호하여 유지보수를 최소화 하는데 그 의의가 있다.
The present invention corresponds to a product using two or more insulating type SMPS, and implements dimming without a separate dimming circuit to maintain a simple and constant lifetime of the LED. In addition, the protection circuit has the meaning of minimizing maintenance by protecting the LED module.

본 발명은 기존 종래조명에서 LED조명으로 교체 시 발생하는 문제점 중 일부를 해결하기 위하여 창안된 것으로, 목적은 보다 심플하게 디밍을 구현하고 유지보수를 최소화 하는데 목적이 있다. LED조명이 급속도로 발전하고 보급됨에 따라 다양한 어플리케이션이 개발되고, 그에 따른 솔루션들을 찾아 해결해야 한다. 또한 시장에서는 저렴하고 효율이 좋은 제품의 요구가 끊이지 않는다. 이러한 상황에서 디밍 시스템을 심플하게 구현하여 비용을 절약 및 효율을 증대 시키고 보호회로를 개발하여 유지보수를 최소화 할 수 있도록 하는 것이 본 발명의 과제이다.
The present invention was devised to solve some of the problems occurring when replacing the conventional lighting from the LED lighting, the object is to implement a dimming more simply and to minimize the maintenance. As LED lighting develops and spreads rapidly, various applications need to be developed and solutions to be found. In addition, there is a constant demand for inexpensive and efficient products in the market. In this situation, it is a task of the present invention to simply implement a dimming system to reduce cost and increase efficiency, and to develop a protection circuit to minimize maintenance.

상기의 목적을 달성하기 위한 방법으로서 2개 이상의 절연타입 SMPS의 출력(DC)을 LED Module에 병렬로 연결하고 각 SMPS 외부전원의 ON/OFF를 통해 디밍을 구현한다. 상기 제어 시 LED Module의 전류를 감지하여 LED Module 불량 발생 시 정상 동작중인 LED Module에 전류 쏠림을 방지하면서 추가 불량을 방지하는 방법이 사용되었다.
As a method for achieving the above object, the output (DC) of two or more insulation type SMPSs are connected in parallel to the LED module, and dimming is realized through ON / OFF of each SMPS external power supply. In the control, a method of detecting an electric current of the LED module to prevent an additional defect while preventing current draw on the normally operating LED module when the LED module is defective is used.

본 발명에 의해, LED 각각 제어가 아닌 동일 동작제어를 통해 LED 수명이 일정하게 보장되고 별도의 디밍회로가 없어 심플하고 저렴하다. 또한 기존 터널등 배선구조를 그대로 이용하므로 설치 및 유지보수가 용이하다.According to the present invention, the LED lifetime is constantly guaranteed through the same operation control rather than the LED control, and there is no separate dimming circuit, which is simple and inexpensive. In addition, it is easy to install and maintain as it uses existing tunnel structure.

상기의 목적을 달성하기 위한 방법으로서 도면에 따라 상세히 설명하면 다음과 같다.When described in detail according to the drawings as a method for achieving the above object is as follows.

도1은 본 발명의 구성도이다. 도1에서 500,600 또는 그 이상의 SMPS는 절연방식의 SMPS를 사용하며 500이라 표기된 SMPS를 제1SMPS 600이라 표기된 SMPS를 제2SMPS라 표기한다.1 is a configuration diagram of the present invention. In FIG. 1, 500, 600 or more SMPSs use an insulation type SMPS, and the SMPS designated as 500 and the SMPS designated as first SMPS 600 are referred to as second SMPS.

제1SMPS와 제2SMPS는 각각 도1 100,200의 외부전원을 입력 받아 절연된 정전류 방식의 직류전원으로 변환하여 700,800의 LED Module 또는 LED Lamp에 공급한다.   The first SMPS and the second SMPS receive the external power of Fig. 1 100,200, respectively, and convert them into insulated constant current DC power and supply them to the LED module or LED lamp of 700,800.

각 SMPS의 전원은 각각 100,200의 외부전원에서 인가되고 300,400의 스위치 ON/OFF에 의해 제1SMPS, 제2SMPS의 동작유무가 결정된다. 300,400 스위치 ON/OFF 즉, SMPS의 동작 수량은 디밍제어 레벨을 결정하고 도1과 같이 모든 SMPS 동작 시 일반동작을 한다. 이는 SMPS의 정전류 제어를 이용한 방식이며 전체 SMPS 출력부 즉, LED Module 연결부를 병렬로 연결하여 동작하는 SMPS의 정전류 셋팅값의 합이 LED Module에 인가되어 디밍제어가 동작하게 된다.The power of each SMPS is applied from an external power source of 100,200, respectively, and the operation of the first SMPS and the second SMPS is determined by 300/400 switch ON / OFF. 300,400 switch ON / OFF, that is, the quantity of SMPS operation determines the dimming control level, and general operation is performed in all SMPS operations as shown in FIG. This is a method using the constant current control of the SMPS, and the sum of the constant current setting values of the SMPSs that operate by connecting all the SMPS output parts, that is, the LED module connection parts in parallel, is applied to the LED module to operate the dimming control.

제품 소비전력 사양에 맞는 출력 전류값을 제1SMPS와 제2SMPS의 정전류 값으로 배분하여 셋팅하고 각 SMPS의 정전류 셋팅값은 서로 동일하지 않아도 된다. 이는 디밍 제어 시 디밍 레벨을 조절할 수 있는 셋팅값이 된다. 단 SMPS 전체 정전류 셋팅값의 합은 제품 출력전류 사양과 동일해야 한다.The output current value that meets the power consumption specifications of the product is divided by the constant current value of the first SMPS and the second SMPS, and the constant current setting value of each SMPS does not have to be the same. This is a setting value to adjust the dimming level when dimming control. However, the sum of SMPS total constant current setting should be the same as product output current specification.

이와 같이 외부전원 ON/OFF, SMPS수량, SMPS 정전류 셋팅값을 통해 디밍제어가 가능하며 SMPS 수량 및 각 SMPS의 정전류 값으로 디밍 레벨을 제어할 수 있다. 즉, 도2와 같이 제1SMPS에만 전원 인가 시 제1SMPS 정전류 셋팅값으로만 LED Module이 동작되고 도3과 같이 제2SMPS에만 전원 인가 시 제2SMPS 정전류 셋팅값으로만 동작된다. 디밍제어를 하지 않고 일반동작으로 제어 시 도1과 같이 제1SMPS, 제2SMPS의 전원을 모두 인가한다. In this way, dimming control is possible through external power ON / OFF, SMPS quantity, SMPS constant current setting value, and dimming level can be controlled by SMPS quantity and constant current value of each SMPS. That is, as shown in FIG. 2, when the power is applied only to the first SMPS, the LED module operates only with the first SMPS constant current setting value, and when the power is applied only to the second SMPS as shown in FIG. 3, the LED module operates only with the second SMPS constant current setting value. In the normal operation without dimming control, the first SMPS and the second SMPS are all powered.

디밍레벨 제어는 각 SMPS의 정전류 셋팅값에 의해 정해지는데 전체 SMPS의 정전류 셋팅값의 합이 제품 출력전류 사양과 동일하게 하면 된다. 예를 들어 제품 출력전류 사양을 100%, 제품 내 SMPS 수량이 2개로 가정하에 각 SMPS 정전류 셋팅값을 10%/90% , 20%/80%, 30%/70%, 40%/60%, 50%/50%로 나누게 되면 나눈 셋팅값과 같은 디밍제어가 가능하며, 2개의 SMPS 모두 ON 상태가 되면 제품은 100%의 일반동작을 하게 된다. Dimming level control is determined by the constant current setting value of each SMPS. The sum of the constant current setting values of all SMPSs should be the same as the product output current specification. For example, assuming 100% product output current specification and 2 SMPS quantities in the product, each SMPS constant current setting value is 10% / 90%, 20% / 80%, 30% / 70%, 40% / 60%, Dividing by 50% / 50% enables dimming control same as the dividing setting value, and when both SMPS are ON, the product will operate at 100% normal operation.

위와 같은 제어 방식에서 문제점은 하나이상의 LED Module의 불량 발생 시 정전류로 셋팅된 SMPS로 인해 정상 동작하는 LED Module로 전류 쏠림 현상이 발생 되어 추가적인 불량발생이 초래 된다. 이 문제점을 컨트롤 할 수 있는 장치가 도1의 900 LED Module 불량 Ddtect이다. In the above control method, the problem is that when one or more LED modules are defective, current deflection occurs to the normally operating LED module due to the SMPS set to constant current, which causes additional failures. The device that can control this problem is the 900 LED Module bad Ddtect of FIG.

이하는 도1 900 LED Module 불량 Detect의 제어방식에 대해 설명한다.The following describes the control method of FIG. 1 900 LED Module Defect.

LED Module 불량 Detect(900)는 도1와 같이 구성되어 동작한다. 이 컨트롤러의 기능은 병렬로 연결 된 2개 이상의 LED Module에서 1개 이상의 LED Module의 불량 발생하게 되면 이 LED Module의 인가되었던 전류는 정상 동작하는 하나 또는 그 이상의 LED Module쪽으로 나누어 인가 된다. 그러면 정상 동작하는 LED Module로 과전류가 인가될 수 있으며 추가적인 불량 발생의 소지가 있다. 이를 방지하기 위해 LED Module의 불량발생 시 불량을 Detect하여 SMPS에 Feedback 신호를 보내면 LED Module의 전류량을 조절하여 정상동작 LED Module에 과전류를 방지하는 컨트롤러 방식이다. 이 기능은 불량 발생 시 추가 불량 발생을 방지하고, 그에 따른 유지보수가 간단하게 되는 효과가 있다. LED module failure Detect (900) is configured and operates as shown in FIG. The function of this controller is that if one or more LED modules fail in two or more LED modules connected in parallel, the applied current of this LED module is divided into one or more LED modules in normal operation. Then, overcurrent may be applied to the normally operating LED module, which may cause additional defects. In order to prevent this problem, when the LED module is defective, it detects the defect and sends a feedback signal to the SMPS. This controller controls the amount of current in the LED module to prevent overcurrent in the normal operation LED module. This function prevents the occurrence of additional defects in the event of a failure, thereby simplifying the maintenance.
