Accordingly, when power is supplied to each lamp through a switch operation in the driver's seat, excessive current flows, which adversely affects the contact point of the switch or the filament of the lamp, and the life of the switch or the lamp. Results in shortening.
그러므로, 이 발명의 목적은 상기한 바와 같은 종래의 기술적 문제점을 해결하기 위한 것으로서, 등화장치를 동작시키기 위한 스위치가 턴온될 때 각 램프의 연결관계가 직렬로 되도록 변환함으로써 각 램프에 흐르는 전류를 감소시켜 스위치나 램프 필라멘트의 수명을 연장시킬 수 있는 자동차용 등화장치 제어회로를 제공하는데 있다.Therefore, an object of the present invention is to solve the conventional technical problems as described above, by reducing the current flowing through each lamp by converting the connection relationship of each lamp in series when the switch for operating the equalizer is turned on. It is to provide an automobile equalizer control circuit that can extend the life of the switch or lamp filament.
상기한 목적을 달성하기 위한 수단으로서 이 발명의 구성은, 일단에 배터리가 연결되며, 사용자의 누름동작에 의해 턴온되는 작동 스위치와; 상기 작동 스위치의 타단에 연결된 제1램프와; 상기 제1램프에 병렬로 연결된 제2램프와; 상기 제1램프의 후단에 연결되어, 턴온 상태인 경우 상기 제1램프가 제2램프에 대해 병렬연결 구조를 가지도록 경로를 형성하고, 턴오프 상태인 경우 상기 제1램프가 제2램프에 대해 직렬연결 구조를 가지도록 경로를 형성하는 제1스위치와; 상기 제2램프의 전단에 연결되어, 제1의 접점에 접속될 경우 상기 제2램프가 제1램프에 대해 병렬연결 구조를 가지도록 경로를 형성하고, 제2의 접점에 접속될 경우 상기 제2램프가 제1램프에 대해 직렬연결 구조를 가지도록 경로를 형성하는 제2스위치와; 일단이 상기 작동 스위치에 연결되고 타단이 접지전위에 연결되어 상기 작동 스위치가 턴온될 경우 상기 제1스위치는 턴오프되도록 하고 상기 제2스위츠는 제2접점에 접속되도록 하는 스위칭 제어수단을 포함하여 이루어진다.As a means for achieving the above object, the configuration of the present invention, the battery is connected to one end, the operation switch is turned on by the user's pressing operation; A first lamp connected to the other end of the operation switch; A second lamp connected in parallel to the first lamp; Is connected to the rear end of the first lamp, when the turn-on state to form a path so that the first lamp has a parallel connection structure with respect to the second lamp, when the turn-off state the first lamp to the second lamp A first switch forming a path to have a series connection structure; When connected to the front end of the second lamp, when the second lamp is connected to form a path so that the second lamp has a parallel connection structure to the first lamp, and when connected to the second contact A second switch forming a path so that the lamp has a series connection structure with respect to the first lamp; One end is connected to the actuation switch and the other end is connected to the ground potential so that the first switch is turned off and the second switch is connected to a second contact when the actuation switch is turned on. .
상기한 이 발명의 구성에서, 상기 스위칭 제어수단은 릴레이 소자에 의해 구현되며, 릴레이 소자의 코일에 전류가 흐를 경우 자력이 발생하며, 이 자력에 의해 상기 제1스위치가 턴오프되고 상기 제2스위치가 제2접점에 접속될 수 있다.In the above configuration of the present invention, the switching control means is implemented by a relay element, the magnetic force is generated when a current flows in the coil of the relay element, the first switch is turned off by the magnetic force and the second switch Can be connected to the second contact.
이에 따라, 상기 작동 스위치의 턴온에 의해 두 개의 램프는 직렬 접속되도록 제어함으로써 각 램프에 병렬 연결시 각 램프에 흐르는 전류의 크기에 비해 1/2이 줄어든 크기의 전류가 흐르게 되며, 과전류에 의한 스위치 접점 불량 또는 램프 필라멘트의 손상은 억제될 수 있다.Accordingly, the two lamps are connected in series by the turn-on of the operation switch, so that when the parallel connection is made to each lamp, a current having a size 1/2 that is reduced compared to the magnitude of the current flowing in each lamp flows, and the switch is caused by an overcurrent switch. Poor contact or damage to the lamp filament can be suppressed.

이하, 첨부된 도면을 참조하여 이 발명의 바람직한 실시예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.
제1도는 이 발명의 실시예에 따른 자동차용 등화장치 제어회로의 상세 회로도이다.1 is a detailed circuit diagram of an equalizer control circuit for an automobile according to an embodiment of the present invention.
제2도의 (a) 및 (b)는 이 발명의 실시예에 따른 자동차용 등화장치 제어회로의 램프 스위치 턴오프시 및 턴온시의 등가 회로도이다.(A) and (b) of FIG. 2 are equivalent circuit diagrams at the time of lamp switch turn-off and turn-on of the automotive equalizer control circuit according to the embodiment of the present invention.
먼저, 제1도를 참조하여 이 발명의 실시예에 따른 자동차용 등화장치 제어회로의 구성을 설명한다.First, with reference to FIG. 1, the structure of the equalizer control circuit for automobiles which concerns on embodiment of this invention is demonstrated.
제1도에 도시된 바와 같이, 이 발명의 실시예에 따른 자동차용 등화장치 제어회로는, 배터리(B)와; 일단이 상기 배터리(B)의 양극에 연결된 작동 스위치(SW1)와; 일단이 상기 작동 스위치(SW1)에 연결되고, 타단이 접지되도록 연결된 릴레이(1)와; 상기 작동 스위치(SW1)와 릴레이 사이의 접점이 연결된 제1램프(LP1)와; 일단이 상기 제1램프(LP1)의 후단에 연결되고 타단이 접지되도록 연결된 제1스위치(SW3)와; 상기 제1램프(LP) 양단이 두 개의 접점(a, b)이 되도록 연결된 제2스위치(SW2)와; 일단이 상기 제2스위치(SW2)에 연결되고, 타단이 상기 제1스위치(SW3)와 공통으로 접지되도록 연결된 제2램프(LP2)로 구성된다.As shown in FIG. 1, an automobile equalizer control circuit according to an embodiment of the present invention includes a battery B; An operation switch SW1 having one end connected to the positive electrode of the battery B; A relay (1) connected at one end to the operation switch (SW1) and connected at the other end to ground; A first lamp LP1 connected with a contact point between the operation switch SW1 and a relay; A first switch SW3 having one end connected to a rear end of the first lamp LP1 and the other end connected to a ground; A second switch SW2 connected to both ends of the first lamp LP so as to be two contacts a and b; One end is connected to the second switch SW2, and the other end is configured as a second lamp LP2 connected to be commonly grounded with the first switch SW3.
다음으로, 상기와 같은 이 발명의 실시예에 따른 자동차용 등화장치 제어회로의 구성에 근거하여 제2도의 등가회로를 참조한 회로의 동작을 설명한다.Next, the operation of the circuit with reference to the equivalent circuit of FIG. 2 will be described based on the configuration of the equalizer control circuit for automobiles according to the embodiment of the present invention as described above.
배터리(B)의 전원이 회로에 공급되면, 회로의 동작이 시작된다.When the power of the battery B is supplied to the circuit, the operation of the circuit starts.
먼저, 운전자에 의해 등화장치가 가동되지 않을 때의 각 스위치의 스위칭 상태를 살펴보면, 작동 스위치(SW1)는 턴오프 상태이고 제1스위치(SW3)는 턴온 상태이며 제2스위치(SW2)는 제1접점(a)에 접속된 상태이다.First, the switching state of each switch when the equalizer is not operated by the driver will be described. The operation switch SW1 is turned off, the first switch SW3 is turned on, and the second switch SW2 is first turned on. It is a state connected to the contact a.
제2도의 (a)는 등화장치가 가동되지 않을 때, 즉 작동 스위치(SW1)가 턴오프 상태일 때, 제1도에 도시된 회로의 등가 회로도이다. 제2도의 (a)를 참조하면, 두 램프(LP1, LP2)는 서로 병렬 연결된 구조를 가짐을 알 수 있다.FIG. 2A is an equivalent circuit diagram of the circuit shown in FIG. 1 when the equalizing device is not operated, that is, when the operation switch SW1 is turned off. Referring to FIG. 2A, it can be seen that the two lamps LP1 and LP2 have a structure connected in parallel with each other.
이때, 운전자의 누름 동작에 의해 작동 스위치(SW1)가 턴온되면, 배터리(B)의 전원이 릴레이(1)에 공급된다.At this time, when the operation switch SW1 is turned on by the driver's pressing operation, the power of the battery B is supplied to the relay 1.
배터리(B)의 전원이 릴레이(1)에 공급되면, 릴레이(1)의 코일에는 전류가 흐르게 되어 자력(Magnetic field)이 생성된다. 이 생성된 자력에 의해 제1스위치(SW3) 및 제2스위치(SW2)는 스위칭 상태가 변화되며, 제1도의 화살표로서 도시된 바와 같은 자력에 의해 각 스위치는 스위칭된다.When the power of the battery B is supplied to the relay 1, a current flows through the coil of the relay 1 to generate a magnetic field. The switching state of the first switch SW3 and the second switch SW2 is changed by the generated magnetic force, and each switch is switched by the magnetic force as shown by the arrow in FIG.
즉, 제1스위치(SW3)는 턴오프 상태로 되며, 제2스위치(SW2)는 제2접점(b)에 접속된다.That is, the first switch SW3 is turned off, and the second switch SW2 is connected to the second contact b.
이에 따라, 두 램프(LP1, LP2)는 제2도의 (b)에 도시된 바와 같이 서로에 대해 직렬 접속 구조를 가지게 된다.Accordingly, the two lamps LP1 and LP2 have a series connection structure with respect to each other as shown in FIG. 2 (b).
각 램프(LP1, LP2)이 내부 저항이 R로서 동일하고, 배터리(B)의 전압이 V로서 일정하다고 가정하면, 두 램프의 병렬 연결시 각 램프에 흐르는 전류 I는로 표현된다.Assuming that each of the lamps LP1 and LP2 has the same internal resistance as R and that the voltage of the battery B is constant as V, the current I flowing through each lamp in parallel connection of the two lamps is It is expressed as
이에 반해, 두 램프(LP1, LP2)가 직렬 연결시에는 배터리 양단저항이 2R이므로, 각 램프에 흐르는 전류 I는로 표현되며, 두 램프(LP1, LP2)가 병렬 연결시에 비해 1/2의 전류가 흐름을 알 수 있다.In contrast, when the two lamps LP1 and LP2 are connected in series, the resistance of the battery at both ends is 2R, so the current I flowing through each lamp is 2 lamps (LP1, LP2) can be seen that the current flow of 1/2 compared to when connected in parallel.
이상에서와 같이 이 발명의 실시예에 따르면, 등화장치가 작동될 때 두 램프의 연결관계가 직렬구조를 가지도록 변환함으로써 각 램프에 흐르는 전류의 크기를 1/2로 감소시켜 스위치의 접점 및 램프 필라멘트의 수명을 연장할 수 있는 저전류 동작을 위한 자동차용 등화장치 제어회로를 제공할 수 있다.As described above, according to an embodiment of the present invention, when the equalization device is operated, the connection relationship between the two lamps is converted to have a series structure, thereby reducing the magnitude of the current flowing through each lamp by one half to the contact point of the switch and the lamp. It is possible to provide an automotive equalizer control circuit for low current operation that can extend the life of the filament.
