미등 감광 해제 기능을 갖는 레오스타트{ RHEOSTAT HAVING TAIL DIMMER CANCLE FUNCTION }Leotard with taillight releasing function {RHEOSTAT HAVING TAIL DIMMER CANCLE FUNCTION}

본 발명은 자동차의 조명 제어 기술에 관한 것으로, 더욱 상세하게는 주간모드와 야간모드로 구분하여 조도를 달리하는 자동차의 조명장치에서 주간모드에서 미등 점등시에 감광을 해제하여 시인성을 향상시켜 안전 운전을 도모할 수 있는 미등 감광 해제 기능을 갖는 레오스타트에 관한 것이다.The present invention relates to a light control technology of a vehicle, and more particularly, in the lighting device of a vehicle having a different illumination by dividing into day mode and night mode, the light is released in the daylight mode to improve visibility and safe driving. The present invention relates to a leotard having a taillight sensitization function capable of achieving

일반적으로, 차량의 실내에서 운전석의 전면에는 각종 주행정보를 제공하는 클러스터(계기판)가 설치되어 있고, 센터 패널상에는 오디오, FATC(풀오토에어컨시스템), 비상등과 같은 각종 스위치류가 배열되어 있다. 이러한 장치들은 야간 주행시 또는 어두운 곳을 주행할 때, 운전자의 시각적 인지를 위하여 조명수단을 내장하고 있다. In general, a cluster (a dashboard) is provided on the front of a driver's seat in the interior of a vehicle, and various switches such as audio, FATC (full auto air conditioner), and emergency lights are arranged on a center panel. These devices have built-in lighting means for the driver's visual perception when driving at night or driving in the dark.

이러한 클러스터 조명수단은 운전자가 전방시야를 주시하면서 차량의 모든 정보를 쉽게 볼 수 있어야 하고, 또렷하고 선명하게 보여주어야 안전 운행이 가능 하므로 그 밝기를 조절할 수 있는 레오스타트이 구비되어 있다.These cluster lighting means should be able to easily see all the information of the vehicle while the driver watches the front view, and it is equipped with a leo start to adjust the brightness of the vehicle because it can be safely driven only by showing clearly and clearly.

도 1은 종래의 자동차용 실내조명 감광 제어장치로서, 레오스타트 스위치의 설치상태를 보여주는 개략도이고, 도 2는 종래의 자동차용 실내조명 감광 제어장치에 대한 개략도이다.1 is a schematic diagram showing the installation of a leotard switch as a conventional indoor lighting control device for a vehicle, Figure 2 is a schematic diagram of a conventional indoor lighting control device for a vehicle.

도 1 및 도 2를 참조하면, 레오스타트(10)은 통상 운전석 하단에 있으며, 노브를 돌려 클러스터(16)의 밝기를 조절할 수 있게 되어 있다. 즉, 눈길 혹은 빗길 등을 운행할 경우, 계기판의 밝기를 낮게 조절하여 운전 집중도를 향상시킴과 아울러 눈의 피로를 감소시킴으로써 안전 운전에 도움을 주게 된다. 이러한 레오스타트(10)에 따른 조명 조절은 레오스타트의 고정 주파수에서 듀티 가변값만을 입력받아 동일한 비율로 LED에 출력함으로써 조명의 밝기를 조절할 수 있다.1 and 2, the leostart 10 is usually located at the bottom of the driver's seat, and the knob can be turned to adjust the brightness of the cluster 16. FIG. In other words, when driving on snowy roads or on rainy roads, the brightness of the dashboard is adjusted to improve driving concentration and reduce eye fatigue, thereby helping to drive safely. The lighting control according to the leostart 10 may adjust the brightness of the illumination by receiving only the duty variable value at the fixed frequency of the leostart and outputting the same to the LED at the same ratio.

자동차의 실내 조명제품에 대한 조명 감광용 조절 장치로 듀티(Duty)비 제어 방식의 레오스타트 스위치(Rheostat Switch:10)는 도 1에 도시된 바와 같이, 운전석 전면 근처에 별도로 설치되어 있는데, 레오스타트 스위치(10)의 조작 방식은 상하 또는 좌우 슬라이딩 방식으로서, 이 스위치의 조작으로 트랜지스터(Tr)을 통한 ILL(-)단의 듀티(Duty)비 제어에 의해 감광량이 조절된다. 따라서 상기 레오스타트 스위치(10)의 조절 및 ILL(-)단의 듀티(Duty)비 제어에 의해 상기 클러스터, FATC, 오디오, 각종 스위치 등에 내장된 조명수단(LED 또는 벌브)의 밝기가 조절되는 것이다.As a dimming control device for a vehicle's interior lighting products, a duty ratio controlled Rheostat Switch: 10 is separately installed near the front of the driver's seat, as shown in FIG. 1. The operation method of the switch 10 is a vertically or horizontally sliding method, and the operation of the switch adjusts the amount of photosensitivity by controlling the duty ratio of the ILL (−) stage through the transistor Tr. Therefore, the brightness of the luminaire (LED or bulb) built into the cluster, FATC, audio, various switches, etc. is controlled by controlling the leostart switch 10 and controlling the duty ratio of the ILL (-) stage. .

한편, 대부분의 자동차 계기용 조명은 주간모드와 야간모드로 구분되어 미등 스위치(TAIL SW:22)가 온되면 주간 밝기의 약 80% 정도의 밝기로 1차 감광이 되도 록 되어 있다(이를 TAIL 감광이라 함).On the other hand, most automotive instrument lights are divided into day mode and night mode, and when the tail light switch (TAIL SW: 22) is turned on, the primary light is reduced to about 80% of the brightness of the daytime (TAIL dimming). ).

따라서 운전자가 주간에도 라이트를 켜고 운행하는 지역에서 미등 스위치를 작동하고 운행시에는 주간임에도 불구하고 야간모드와 같이 약 80% 정도의 밝기로 감광되어 시인성이 저하되는 문제점이 있다. 특히, 운전자가 선글라스를 착용하고 운전하는 경우에는 감광에 의해 더욱 시인성이 저하되는 문제점이 있다.Therefore, the driver operates the taillight switch in an area where the driver turns on the light even in the daytime, and there is a problem in that visibility is reduced by about 80% of the brightness as in the night mode in spite of the daytime. In particular, when the driver is wearing sunglasses to drive, there is a problem that visibility is further reduced by photosensitization.

본 발명은 상기와 같은 문제점을 해소하기 위해 제안된 것으로, 본 발명의 목적은 레오스타트 2단 스위치 작동시 미등 감광을 해제하도록 신호를 출력하여 미등 점등에 따른 감광을 해제하여 운전자에게 시인성을 향상시켜줄 수 있도록 된 미등 감광 해제 기능을 갖는 레오스타트을 제공하는 것이다.The present invention has been proposed to solve the above problems, an object of the present invention is to output a signal to release the taillight dimming when operating the Leostart two-stage switch to release the dimming according to the lighting of the taillight to improve visibility to the driver It is to provide a Leostart with a taillight canceling function.

상기 레오스타트은 과전압과 역전압, 서지, 및 정전기로부터 보호하는 보호회로가 포함되고 전원을 입력받아 정전압을 제공하는 전원입력단회로를 더 구비할 수 있고, 상기 듀티 출력 제어부는 마이컴으로 구현되어 미등 스위치(TAIL SW)가 온된 상태에서 가변저항을 조절하면 가변저항값에 따라 듀티비와 주파수를 조절하여 조명 밝기를 조절하고, 가변저항이 최대(MAX)인 조건에서 2단 스위치가 작동하면 감광 해제 명령을 발생하여 각 조명장치들이 1차 감광을 해제하도록 하는 것이 다.The Leostart includes a protection circuit to protect against overvoltage, reverse voltage, surge, and static electricity, and may further include a power input terminal circuit configured to receive power and provide a constant voltage. When the variable resistor is controlled while the TAIL SW is on, the illumination brightness is controlled by adjusting the duty ratio and frequency according to the variable resistor value, and when the two-stage switch is operated under the condition that the variable resistor is MAX, To cause each of the luminaires to release the primary light.

본 발명에 따른 레오스타트은 미등 점등시 조명장치의 밝기를 직접 조절할 수 있고, 가변저항의 최대값(MAX) 위치에서 2단 스위치 작동시에는 미등(TAIL) 감광을 해제하라는 신호를 출력하여 각 조명장치들이 1차 감광을 해제함으로써 운전중에 시인성이 향상되어 안전운전을 도모할 수 있다. 즉, 본 발명에 따르면 주간에도 헤드램프를 켜고 운행해야 하는 지역이나 시동 온시 무조건 헤드램프가 켜지는 지역에서 미등 스위치(TAIL ON)를 작동하고 운행시 좀더 밝은 조명을 원하는 운전자에게 1차 감광을 해제하여 주간 밝기를 내도록 함으로써 안전운행을 가능하게 한다.Leostart according to the present invention can directly adjust the brightness of the lighting device when the taillight is turned on, and when the two-stage switch operation at the maximum value (MAX) of the variable resistor outputs a signal to cancel the taillight (TAIL) dimming each lighting device By releasing the primary photosensitivity, visibility is improved during driving, and safe driving can be achieved. That is, according to the present invention to operate the taillight switch (TAIL ON) in the area where the headlamp is turned on and running even in the daytime or the headlamp is turned on unconditionally, and releases the primary dimming to the driver who wants a brighter light when driving. It is possible to drive safely by giving daytime brightness.

The power converter 140 controls and outputs a dimmer cancel signal.

이러한 레오스타트(100)은 제1 단자(101)가 커넥터를 통해 TAIL SW와 연결되어 조명전원 ILL+를 입력받고 제2 단자(102)는 접지와 연결된다. 레오스타트(100)의 제3 단자(103)는 커넥터를 통해 조명전원(ILL-)을 PWM 출력으로 출력하고, 제4 단자(104)는 감광 해제 신호(Dimmer Cancel Signal)를 출력한다.The Leostart 100 has a first terminal 101 is connected to the TAIL SW through the connector to receive the lighting power ILL + and the second terminal 102 is connected to the ground.
