본 발명은 전극의 연결이 용이한 등기구용 인쇄회로기판에 관한 것으로서, 보다 상세하게는 두 개의 LED보드를 전기적으로 연결하기 위한 단자를 넓게 형성하여 연결와이어가 꼬이지 않게 연결할 수 있도록 하는 전극의 연결이 용이한 등기구용 인쇄회로기판에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a printed circuit board for a luminaire in which an electrode can be easily connected, more specifically, a terminal for electrically connecting two LED boards is widened so that connection of electrodes, To a printed circuit board for an easy luminaire.

전력 소모량을 줄이고, 밝기를 향상시키기 위해 LED를 발광소자로 사용하는 등기구가 많이 개시되고 있다.Many luminaire use LED as light emitting element to reduce power consumption and improve brightness.

일반적인 LED 등기구는 얇은 판상의 인쇄회로기판(PCB)의 표면에 하나 또는 복수의 LED를 실장시키고, LED에 직류전원을 공급하여 빛을 방출하도록 하는 구조를 갖는다.A typical LED luminaire has a structure in which one or a plurality of LEDs are mounted on a surface of a thin plate printed circuit board (PCB), and DC power is supplied to the LEDs to emit light.

최근 개시되고 있는 LED 등기구는 기존의 막대 모양의 형광등을 대체하는 용도로 많이 사용되는데, 기존 형광등의 케이스나 반사판을 활용하기 위해서 막대 모양으로 제작되는 경우가 많이 있다. 이런 등기구 내부에는 직사각형 모양의 인쇄회로기판이 설치되는데, 등기구의 길이에 따라서는 여러 개의 인쇄회로기판을 연결하여 사용하기도 한다.Recently, the LED luminaire is widely used as a substitute for a conventional rod-shaped fluorescent lamp. In many cases, a rod-shaped LED lamp is used to utilize the case or reflector of a conventional fluorescent lamp. Inside this luminaire, a rectangular printed circuit board is installed. Depending on the length of the luminaire, several printed circuit boards may be connected and used.

도 1은 종래기술에 따른 LED 등기구용 인쇄회로기판의 구조를 나타낸 사시도이며, 도 2는 도 1에 도시된 인쇄회로기판의 연결방식을 나타낸 평면도이다.FIG. 1 is a perspective view showing a structure of a printed circuit board for an LED lamp according to a related art, and FIG. 2 is a plan view showing a connection method of the printed circuit board shown in FIG.

등기구 내부에 설치되는 인쇄회로기판(100)은 비교적 얇은 장방형의 LED보드(102) 위에 다수의 LED소자(104)가 실장되는 형태로 만들어진다. LED소자(104)에는 직류전원이 공급되어 발광작용이 이루어진다.The printed circuit board 100 installed inside the lamp is made in a configuration in which a plurality of LED elements 104 are mounted on a relatively thin rectangular LED board 102. DC power is supplied to the LED element 104 to perform a luminescent action.

LED소자(104)에 전력을 공급하기 위해서 LED보드(102) 위에는 두 개의 전극패턴(106, 108)이 형성된다. 전극패턴(106, 108)은 LED보드(102)의 표면에 길이방향으로 좌우측에 각각 형성되며, 가운데에 위치한 LED소자(104)와 전기적으로 연결된다.Two electrode patterns 106 and 108 are formed on the LED board 102 to supply power to the LED element 104. [ The electrode patterns 106 and 108 are formed on the left and right sides of the LED board 102 in the longitudinal direction, respectively, and are electrically connected to the LED elements 104 located in the center.

일반적으로 직선 모양으로 형성되는 전극패턴(106, 108) 중에서 제1전극패턴(106)은 전원공급부의 양극(+)에 연결되고, 제2전극패턴(108)은 음극(-)에 연결된다.The first electrode pattern 106 is connected to the positive electrode of the power supply unit and the second electrode pattern 108 is connected to the negative electrode of the electrode patterns 106 and 108 formed in a straight line.

제1전극패턴(106)과 제2전극패턴(108)은 LED보드(102)의 표면에 일측 말단에서 타측 말단까지 연결되는데, 두 개의 LED보드(102)를 연결하여 사용하는 경우에는 각각의 보드에 형성된 패턴을 서로 전기적으로 연결시켜야 한다.The first electrode pattern 106 and the second electrode pattern 108 are connected to the surface of the LED board 102 from one end to the other end. When two LED boards 102 are connected to each other, It is necessary to electrically connect the patterns formed on the electrodes.

이를 위해서 도 2에 도시된 바와 같이, 전극패턴(106, 108)의 말단부에 형성된 서로 다른 전극을 두 개의 연결와이어(110, 112)로 연결한다.For this purpose, as shown in FIG. 2, the electrodes formed at the distal ends of the electrode patterns 106 and 108 are connected by two connecting wires 110 and 112.

그런데 전극패턴(106, 108)의 말단부에 형성된 전극이 반대가 되기 때문에 전극을 연결하기 위해서는 아래위로 연결와이어(110, 112)가 겹쳐지거나 꼬이게 된다. 기판의 연결부위가 복잡하게 겹쳐지지 않도록 하기 위한 접속장치들이 개시되고 있지만, 이러한 접속장치를 사용하면 발광부의 구조가 복잡해지고 크기가 커지는 문제점이 있었다.However, since electrodes formed at the distal ends of the electrode patterns 106 and 108 are opposite to each other, the connecting wires 110 and 112 are overlapped or twisted to connect the electrodes. There has been disclosed a connection device for preventing connection portions of a substrate from being complicatedly overlapped. However, when such a connection device is used, there has been a problem that the structure of the light-emitting portion becomes complicated and the size becomes large.

[

제1양극단자(206a)와 제2양극단자(206b)는 일정한 거리만큼 이격되어 있는데, 이 사이는 제1양극연결부(206c)에 의해 전기적으로 연결된다. 제1양극연결부(206c) 역시 제1전극패턴(206)과 같은 재질의 도전체로 인쇄된다.The first anode terminal 206a and the second anode terminal 206b are spaced apart from each other by a predetermined distance, and the first anode terminal 206a and the second anode terminal 206b are electrically connected by the first anode connection portion 206c.

The first anode terminal 208d is formed on the rear side of the LED board 202 rather than the first anode connection portion 206c in an insulated state from the first anode connection portion 206c. The first negative electrode terminal 208d is electrically connected to the second electrode pattern 208. [

한편, LED보드(202)의 타측 말단에는 일측 말단과는 대칭되는 형태의 단자가 형성된다. 즉, 타측 말단에는 제3양극단자(208a)와 제4양극단자(208b)가 길이방향으로 좌우측에 나란하게 형성되며, 제3양극단자(208a)와 제4양극단자(208b) 사이에도 제2양극연결부(208c)가 인쇄된다. 제2전극패턴(208)과 제3양극단자(208a), 제4양극단자(208b), 제2양극연결부(208c)는 모두 전기적으로 연결된다.On the other hand, at the other end of the LED board 202, a terminal is formed which is symmetrical with the one end.

The second cathode terminal 206d is electrically connected to the first electrode pattern 206. [

따라서 제1양극단자(206a) 또는 제2양극단자(206b)를 통해 인입된 전류는 제1전극패턴(206)을 통과해서 제2음극단자(206d)로 전달된다. 또한 제1음극단자(208d)를 통해 인입된 전류는 제2전극패턴(208)을 통과해서 제3양극단자(208a) 또는 제4양극단자(208b)로 전달된다.Accordingly, the current drawn through the first positive electrode terminal 206a or the second positive electrode terminal 206b passes through the first electrode pattern 206 and is transmitted to the second negative electrode terminal 206d. The current drawn through the first negative electrode terminal 208d passes through the second electrode pattern 208 and is transmitted to the third positive electrode terminal 208a or the fourth positive electrode terminal 208b.

The anode and the cathode are connected to each other so that the cathode and the cathode correspond to each other.

이를 위해서 제1양극단자(206a)와 제4양극단자(208b)를 연결하고, 제2양극단자(206b)와 제3양극단자(208a)를 연결한다. 그리고 제1음극단자(208d)와 제2음극단자(206d)를 연결한다. 이렇게 되면 연결와이어(210)를 겹치거나 꼬이게 하지 않고도 두 개의 LED보드(202)를 전기적으로 연결할 수 있다.To this end, the first positive terminal 206a and the fourth positive terminal 208b are connected, and the second positive terminal 206b and the third positive terminal 208a are connected. And connects the first negative electrode terminal 208d and the second negative electrode terminal 206d.
