본 발명은 광센서의 입사광량 조절기구에 관한 것이며, 상세하게는 자동차의 헤드 램프, 테일 램프 등을 자동으로 점멸하는 광센서의 입사광량 조절기구에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incident light amount adjusting mechanism of an optical sensor, and more particularly, to an incident light amount adjusting mechanism of an optical sensor that automatically flashes a head lamp, a tail lamp, and the like of an automobile.

주지하는 바와 같이 자동차의 헤드 램프 및 테일 램프는 특정한 국가를 제외하고는 주간소등ㆍ야간점등을 하는 것이 통상적이고, 상기한 주간소등ㆍ야간점등의 경우에는 운전자의 편의성을 향상하기 위하여 자동점멸수단을 채용하고 있다.As is known, automobile headlamps and tail lamps are normally turned off during the daytime except for a specific country. In the case of turning off the lights during the daytime or at night, automatic flashing means is provided to improve the driver's convenience. .

상기 자동점멸수단은 통상적으로 광센서를 이용하고 있는바, 종래의 광센서는 도 1에서 참조되는 바와 같이 케이스(10)에 포토다이오드(photodiode), 포토트랜지스터(phototransistor), 포토IC, CdS(황화카드뮴)셀 등의 센서 엘리먼트(11)를 내장하고, 상기 케이스(10)의 상부에 창유리(12)를 덮은 것으로서, 주간에는 입사광량이 많음으로 센서 엘리먼트(11)의 저항이 작기 때문에 헤드 램프 등은 켜지지 않은 상태에 있게 되고, 야간에는 입사광량이 거의 없음으로 저항이 커서 헤드 램프 등은 켠 상태를 유지하는 것이다.1, the conventional optical sensor is provided with a photodiode, a phototransistor, a photo IC, a CdS (yellow light emitting diode) Cadmium) cell or the like and the window glass 12 is covered on the upper part of the case 10. Since the resistance of the sensor element 11 is small due to a large amount of incident light in the daytime, And the head lamp is kept turned on because the resistance is large because there is almost no incident light amount at night.

그러나 상기한 램프의 자동점멸기구는 광센서의 제어는 일정조도만으로 하도록 되어 있음으로 예를 들어 주간에 안개가 낀 지역을 주행할 경우 입사광량은 많아서 램프는 켜지지 않으나 안전운전을 위하여 헤드 램프와 테일 램프를 켜야할 필요성이 있게 되지만 그 필요성에 부응하지 못하거나, 중고차의 경우 램프의 켜짐을 지연 내지 억제하려고 할 경우에도 램프가 켜지는 문제점이 있는 것이다.However, in the automatic flicker mechanism of the above-mentioned lamp, since the light sensor is controlled only by a certain degree of illumination, for example, when the fog area is driven in the daytime, the amount of incident light is large and the lamp is not turned on. However, There is a need to turn on the lamp, but it is not possible to meet the necessity, or in the case of a used car, there is a problem that the lamp is turned on even when the lamp is to be delayed or suppressed.

본 발명은 상기한 실정을 감안하여, 램프를 자동점멸수단에 의하여 점멸함과 아울러 운전자가 센서 엘리먼트에 입사되는 광량을 임의조절하여 주위환경 등에 부합되게 점멸할 수 있도록 한 광센서의 입사광량 조절기구를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION In view of the above-described circumstances, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide an incidence light amount adjusting mechanism And to provide the above-mentioned objects.

The control device 36 is provided with a diaphragm mechanism 32, The configuration will hayeoseo.

상기 로터(20)는 케이스(10)의 상면에 지지링(120)을 형성하고, 로터(20)의 저면에 지지홈(121)을 형성하여 지지홈(121)을 지지링(120)에 삽입하여 간단한 구성으로 설치한 것이다.The rotor 20 has a support ring 120 formed on the upper surface of the case 10 and a support groove 121 formed on the bottom surface of the rotor 20 to insert the support groove 121 into the support ring 120 And is installed in a simple configuration.

상기 조리개기구(32)는 판상 마름모 형상의 조리개본체(130)의 하나의 꼭지점에 일정간격을 두고 지지돌기(131a)(131b)를 형성하고, 상기 지지부재(30)에 지지홈(132)을 형성하여 지지돌기(131a)(131b)를 지지홈(132)에 삽입 지지하고, 상기 지지돌기(131a)(131b)가 형성된 꼭지점과 직각위치의 일측 꼭지점 부위를 상기 입사광 통과공(27)의 주위에 핀(133)으로 힌지 결합하여서 로터(20)를 회전하면 지지돌기(131a)(131b) 형성부위가 핀(133)을 지점으로 시계방향 또는 반시계방향으로 회전함으로써 입사광 통과공(27)의 면적의 증감을 간편하게 조절할 수 있도록 한 것이다.The diaphragm mechanism 32 includes support protrusions 131a and 131b at regular intervals on one vertex of the plate-shaped rhombic diaphragm body 130 and supports the support protrusions 131 131b are inserted into and supported by the support grooves 132 and one vertex portion at a position perpendicular to the vertex of the support protrusions 131a, 131b is formed in the vicinity of the incident light passage hole 27 When the rotor 20 is rotated by hinging with the pin 133, the portion where the support protrusions 131a and 131b are formed rotates clockwise or counterclockwise around the pin 133, So that the increase and decrease of the area can be easily controlled.

이상과 같은 본 발명은 스위치(35)를 조작하지 않고, 또한 조리개기구(32)가 입사광 통과공(27)을 조금 닫은 상태로 유지하여 입사되는 입사광량만으로써 종래와 같이 램프를 자동점멸하며, 운전자가 센서 엘리먼트(11)에 입사되는 입사광량을 주변의 환경 등을 이유로 조절할 경우 예를 들어 안개지역을 통과할 때에는 모터 (23)에 의하여 피니온(22)을 구동하고 로터(20)를 반시계방향으로 회전시키면 로터 (20)가 회전함에 따라 그 내부주위에 형성한 지지부재(30)의 지지홈(132)에 조리개본체(130)의 꼭지점에 형성한 지지돌기(131a)(131b)가 삽입 지지된 상태로 핀(133)을 지점으로 조리개기구(32)가 회전함으로써 입사광 통과공(27)의 면적을 축소하게 되고(도 4 참조), 상기와 같이 입사광 통과공(27)의 면적이 축소되면 센서 엘리먼 트(11)의 저항이 크게 됨으로 램프가 켜지는바, 상기와 같이 안개지역 통과시 램프가 켜지면 자기 차의 식별이 양호하여 안전사고를 예방할 수 있는 것이다.The present invention as described above allows the iris mechanism 32 to keep the incident light passage hole 27 in a slightly closed state without operating the switch 35, When the driver controls the amount of incident light incident on the sensor element 11 due to the surrounding environment or the like, for example, when passing through the fog area, the motor 23 drives the pinion 22, The support protrusions 131a and 131b formed at the apexes of the diaphragm main body 130 are formed in the support grooves 132 of the support member 30 formed around the inside of the rotor 20 as the rotor 20 rotates The area of the incident light passage hole 27 is reduced by rotating the diaphragm mechanism 32 with the pin 133 as a fulcrum in the state of being inserted and supported (see FIG. 4) The resistance of the sensor element 11 is increased, If the lamp is turned on when passing through the fog area as described above, it is possible to prevent a safety accident because the identification of the own vehicle is good.

그리고 중고차의 경우 램프의 켜짐을 억제할 때에는 로터(20)를 시계방향으로 회전하면 입사광 통과공(27)의 면적이 증대됨으로써 램프의 켜짐을 지연 내지 방지할 수 있는 것이다.In the case of using a used car, when turning on the lamp is suppressed, the area of the incident light passage hole 27 is increased by rotating the rotor 20 in the clockwise direction, thereby delaying or preventing the lamp from being turned on.

이상과 같이 본 발명은 광센서에 조리개기구를 설치하여 센서 엘리먼트에 입사되는 광량을 임의조절함으로써 운전자의 의도대로 램프를 켜거나 켜짐을 지연 내지 억제할 수 있음으로 주위환경 등에 부합되는 운전을 함으로써 안전운전을 함과 아울러 배터리의 수명을 양호하게 연장할 수 있는 것이다.As described above, according to the present invention, a diaphragm mechanism is provided in the optical sensor to arbitrarily adjust the amount of light incident on the sensor element, thereby delaying or suppressing the lamp from being turned on or off according to the driver's intention. And the life of the battery can be extended well.
