본 발명은 차량후면에 조사되는 태양광의 각도에 대응하여 제동 등의 발기가 변동되도록 하는 제동등 광도조절 시스템에 관한 것이다.The present invention relates to a braking light intensity control system for changing the erection of the braking light in response to the angle of sunlight irradiated to the rear of the vehicle.
자동차에는 제1도에 도시된 바와 같이, 브레이크페달을 밟았을 때 연동되는 브레이크스위치(S1)에 의해서 배터리전원이 공급되어 점등되는 복수의 제동등(LP1,LP2)이 구비되며, 제2도에 도시된 바와 같이 상기 복수의 제동등(LP1, LP2)을 덮는 적색의 두 투광커버(3, 3')가 차체후방의 좌우측에 각각 설치되어, 뒤에서 주행하는 차량의 운전자에게 적색불빛의 제동신호를 전달하도록 구성된다.As shown in FIG. 1, the vehicle is provided with a plurality of brake lights LP1 and LP2 which are turned on by being supplied with battery power by the brake switch S1 interlocked when the brake pedal is pressed, as shown in FIG. As described above, two red floodlight covers 3 and 3 'covering the plurality of brake lamps LP1 and LP2 are respectively installed at the left and right sides of the rear of the vehicle body to transmit a red light braking signal to the driver of the vehicle driving behind. It is composed.
이러한 종래의 제동등(LP1, LP2)은 점등되는 광도가 일정하므로, 태양광이 밝은 날에 차의 후방에서 태양광이 비치게 되면, 투광커버들(3, 3')을 투과한 태양광이 제동등(LP1, LP2)의 점등효과를 감소시키게 된다.Since the brightness of the conventional brake lights LP1 and LP2 is constant, when sunlight shines from the rear of the car on a bright day, sunlight transmitted through the floodlight covers 3 and 3 'is braked. The lighting effect of (LP1, LP2) is reduced.
특히, 태양고도가 낮은 조석에는 제3도에 도시된 바와 같이, 태양광(a)이 본 차량(A)의 투광커버(3, 3')에 반사되어 후방차량(B)의 운전자에게 전달되므로, 후방차량(B)의 운전자는 전방차량의 제동등(LP1, LP2)이 점등된 상태인지를 분간하기가 더욱 어렵게 된다.In particular, in the low tidal tide, as shown in FIG. 3, the sunlight a is reflected by the floodlights 3 and 3 ′ of the vehicle A and transmitted to the driver of the rear vehicle B. It is more difficult for the driver of the rear vehicle B to distinguish whether the braking lights LP1 and LP2 of the front vehicle are lit.
이러한 점을 해결하기 위해 제동등에 소비전력이 큰 고광도의 램프를 채용한다면, 이 램프가 너무 밝아 야간에 후방차량의 운전자의 시야를 방해하게 되므로 사고를 유발할 우려가 있어 실제적으로 적용이 불가능하다.In order to solve this problem, if a high-intensity lamp with a high power consumption is used for the braking lamp, the lamp may be too bright to obstruct the driver's view of the rear vehicle at night, which may cause an accident, and thus cannot be practically applied.
이러한 제반 문제점을 해결하기 위한 본 발명은 차량의 후방에 조사되는 태양광의 영향이 크게 되면 제동 등을 높은 광도로 점등하고, 차량의 후방에 조사되는 태양광의 영향이 작게 되면 제동 등을 낮은 광도로 점등하는 제동등 광도조절 시스템을 제공하려는 목적이 있다.The present invention for solving the above problems is to turn on the braking light to a high brightness when the influence of sunlight irradiated to the rear of the vehicle is large, and to turn on the braking light to a low brightness when the influence of sunlight irradiated to the rear of the vehicle is small The purpose of the present invention is to provide a light control system.
이러한 목적을 달성하기 위한 본 발명은 차량후면으로 조사되는 태양광(a)의 광각에 대응하여 횡방향 및 종방향의 2진신호의 데이터를 각각 검출하는 두 광각 감지부(10, 10')와, 상기 두 광각 감지부(10, 10')에서 출력되는 2진신호의 데이터들을 메모리(30)에 설정된 명령에 따라 연산한 후, 이 출력데이타신호에 대응하여서 브레이크스위치(S1)를 통해 공급되는 전원전류를 조절하여 출력하는 콘트롤러(20)와, 상기 콘트롤러(20)의 출력전류에 따라 점등광도가 변동되는 복수의 제동등(LP1, LP2)으로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides two wide-angle detectors 10 and 10 'for detecting data of binary signals in the lateral direction and the longitudinal direction, respectively, corresponding to the wide angle of the sunlight a emitted to the rear of the vehicle. After calculating the data of the binary signals output from the two wide-angle sensing units 10 and 10 'according to a command set in the memory 30, the brake signals are supplied through the brake switch S1 in response to the output data signal. And a plurality of brake lamps LP1 and LP2 whose lighting intensity is varied according to the output current of the controller 20 and the controller 20 for outputting the power supply current.
또한, 본 발명의 다른 특징은 상기 광각감지부들(10, 10')은 각각 차량후면의 투광커버(3, 3')와 인접설치되며, 종방향 및 횡방향의 슬릿(11a, 11b)이 형성된 각각의 차광커버(11, 11')와, 상기 차광커버(11, 11')의 내측에 형성되며, 상기 콘트롤러(20)에 전기적으로 접속되는 다수의 포토다이오(PD)가 비트단위의 라인(L0-L8)상에 그레이코드패턴으로 배치되는 각각의 수광판(12, 12')으로 각각 구성되는 것이다.In addition, another feature of the present invention is that the wide-angle sensing units 10 and 10 'are installed adjacent to the floodlight covers 3 and 3' on the rear of the vehicle, respectively, and the slits 11a and 11b in the longitudinal and transverse directions are formed. Each of the light blocking covers 11 and 11 ′ and a plurality of photodiodes PD formed on the inside of the light blocking covers 11 and 11 ′ and electrically connected to the controller 20 are arranged in a bit unit line ( Each of the light receiving plates 12 and 12 'disposed on the L0-L8 in a gray code pattern.
이하, 도면을 참조하여 본 발명의 바람직한 실시예를 더욱 상세히 설명한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention in more detail.
제4도는 본 발명의 블록구성도이고, 제5도의 (a)와 (b)는 본 발명에 의한 두 광각감지부의 분해사시도이고, 제6도의 (a)와 (b)는 본 발명에 의한 두 수광판의 평면구성도이고, 제7도는 본 발명에 의한 차체후방의 외관사시도이다.Figure 4 is a block diagram of the present invention, Figure 5 (a) and (b) is an exploded perspective view of the two wide-angle detection unit according to the present invention, Figure 6 (a) and (b) is a two Fig. 7 is a plan view of the light receiving plate, and Fig. 7 is an external perspective view of the rear of the vehicle body according to the present invention.
제4도에 도시된 바와 같이, 본 발명은 차량후면으로 조사되는 태양광(a)의 광각을 가로방향 및 세로방향의 2진 데이터로 검출하는 횡축 광각 감지부(10)와 종축 광각감지부(10')의 출력단에 2진신호의 데이터들을 설정된 명령에 따라 연산하여 광각을 판별하는 콘트롤러(20)가 접속되고, 상기 콘트롤러(20)는 상기 두 광각감지부(10, 10')에서는 입력되는 2진신호의 데이터들을 일시저장하며 이 데이터들의 연산명령이 저장되는 메모리(30)에 접속된다. 상기 메모리(30)에 저장되는 연산명령은 본 차량(A)의 후방에 조사되는 태양광(a)에 의해 후방차량(B)의 운전자가 시각적인 영향을 받는지를 분석하는 것이다.As shown in FIG. 4, the present invention is a horizontal axis angle detection unit 10 and vertical axis angle detection unit for detecting the wide angle of the sunlight (a) irradiated to the rear of the vehicle as the horizontal and vertical binary data ( 10 ') is connected to a controller 20 for determining the wide angle by operating the data of the binary signal according to a set command, the controller 20 is input from the two wide-angle detection unit (10, 10') The data of the binary signal are temporarily stored and connected to a memory 30 in which an operation instruction of the data is stored. The operation command stored in the memory 30 is to analyze whether the driver of the rear vehicle B is visually affected by the sunlight a emitted to the rear of the vehicle A.
또, 상기 콘트롤거(20)는 브레이크페달의 접속상태에 따라 전원전류를 공급하는 브레이크스위치(S1)와 차에 마련된 복수의 제동등(LP1, LP2)의 사이에 접속되어서, 상기 두 광각감지부(10, 10')에서 콘트롤러(20)로 입력된 데이터의 연산결과에 댕응해서 상기 브레이크스위치(S1)에서 공급되는 전원의 전류값을 조절하여 출력하도록 구성된다. 이와같은 콘트롤러(20)의 출력되어 제동등(LP1, LP2)으로 공급되는 전류값이 변동되도록 하려면, 콘트롤러(20)내에 전류제어소자로 구성되는 회로를 내장시키면 된다.In addition, the controller 20 is connected between the brake switch S1 for supplying a power current according to the connection state of the brake pedal and the plurality of brake lamps LP1 and LP2 provided in the vehicle, so that the two wide-angle detection units ( 10, 10 ') is configured to adjust and output the current value of the power supplied from the brake switch S1 in response to the operation result of the data input to the controller 20. In order to change the value of the current output from such a controller 20 and supplied to the brake lamps LP1 and LP2, a circuit composed of a current control element may be incorporated in the controller 20.
이와 같이 태양광이 광각에 대응하는 전원전류를 출력하는 콘트롤러(20)는 차에 마련된 복수의 제동등(LP1, LP2)에 공통접속된다. 여기서, 상기 제동등들(LP1, LP2)은 종래의 것보다 고광도의 빛을 발산하는 높은 소비전력의 것을 사용하는 것이 바람직한데, 이는 제동등이 태양광(a)의 영향을 많이 받게 될 때는 높은 광도로 점등되도록 한 것으로, 태양광(a)의 영향이 없을 때에는 낮은 광도로 점등되는 것이 가능함은 물론이다.As such, the controller 20 for outputting a power supply current corresponding to the wide angle of sunlight is commonly connected to the plurality of brake lamps LP1 and LP2 provided in the vehicle. Here, the braking lamps LP1 and LP2 preferably use a higher power consumption that emits higher brightness than the conventional one, which is high when the braking light is affected by sunlight a. It is to be turned on, it is possible to be turned on at a low luminous intensity when there is no influence of sunlight (a).
또한, 상기 횡축 광각감지부(10)는 제5도의 (a)와 제6도의 (a)에 도시된 바와 같이, 횡방향으로 슬릿(11a)이 형성된 차광커버(11)와,상기 차광커버(11)의 내측에 형성되며, 다수개의 포토다이오(PD) 가 비트단위의 종방향 라인(LO-L8)상에 그레이코드식 패턴으로 배치되는 수광판(12)으로 구성되어서, 제7도에 도시한 바와 같이 차체의 후면에 부착되어 태양광(a)의 고도를 감지하도록 한 것이다.In addition, as illustrated in FIGS. 5A and 6A, the horizontal axis wide angle detection unit 10 includes a light blocking cover 11 having a slit 11a formed in a horizontal direction, and the light blocking cover 11 is formed inside the light receiving plate 12 formed in a gray coded pattern on the bit line longitudinal line LO-L8, which is formed inside of FIG. As it is attached to the rear of the body to detect the altitude of the sunlight (a).
그리고, 상기 종축 광각감지부(10')는 제5도의 (a)와 제6도의 (b)에 도시한 바와 같이, 차광판(11')의 슬릿(11b)이 종방향으로 형성되고, 수광판(12')의 포토다이오드(PD)가 배치되는 라인(L0-L8)방향이 횡방향으로 형성된 것 외에는 상기 횡축 광 각감지부(10)와 동일하며, 제7도에 도시된 바와 같이, 상기 횡축 광각감지부(10)와 함께 본 차량(A)의 후면에 부착되어서, 태양광(a)의 측도를 감지하도록 한 것이다.In addition, the longitudinal axis wide-angle detection unit 10 'includes a slit 11b of the light blocking plate 11' formed in the longitudinal direction, as shown in FIGS. 5A and 6B. The line axis L0-L8 in which the photodiode PD of 12 'is disposed in the transverse direction is the same as the transverse light angle detecting unit 10, and as shown in FIG. It is attached to the rear of the vehicle A together with the wide angle detection unit 10, so as to sense the side view of the sunlight (a).
이와 같이 구성된 본 발명은 제3도에 도시된 바와 같이, 태양광(a)이 본 차량(A)의 정후방에서 조사되면, 태양광(a)은 제7도에 도시된 바와 같이 두 광각감지부(10, 10')의 차광커버(11, 11')에 형성된 각각의 슬릿(11a, 11b)을 통해 두 수광판(12, 12')으로 입사되는 데, 이때 제5도에 도시된 바와 같이, 광이 입사된 위치에 있는 포토다이오드(PD)들에서는 라인(L0-L8)의 수만큼의 비트단위로 2진신호를 검출하여 데이터로서 출력하게 된다. 따라서, 태양의 고도에 해당되는 2진신호의 데이터와, 차량후면에 대한 태양의 측방향각도에 해당되는 2진신호의 데이터를 얻을 수 있게 되며, 태양의 고도가 변동되면 그에 따른 데이터는 그레이코드패턴으로 변동된다.As shown in FIG. 3, when the solar light a is irradiated from the front and rear of the vehicle A, the solar light a has two wide-angle detections as shown in FIG. 7. It is incident to the two light receiving plates 12 and 12 'through the respective slits 11a and 11b formed in the light shielding covers 11 and 11' of the portions 10 and 10 ', as shown in FIG. Likewise, in the photodiodes PD at the position where light is incident, the binary signals are detected in bit units as many as the lines L0-L8 and output as data. Therefore, the data of the binary signal corresponding to the altitude of the sun and the data of the binary signal corresponding to the lateral angle of the sun with respect to the rear of the vehicle can be obtained. When the altitude of the sun changes, the corresponding data is gray coded. Fluctuates into patterns.
이와 같은 두 종류의 2진신호의 데이터가 입력되는 콘트롤러(20)는 이 데이터들을 메모리(30)에 일시 저장한 후, 상기 2진신호의 데이터들을 메모리(30)에 설정된 명령에 따라 연산하여 본 차량(A)의 후방에 조사되는 태양광(a)이 후방차량(B)의 운전자에게 영향을 끼치는지를 분석하고, 이와같이 연산된 출력데이타에 대응하여 브레이크스위치(S1) 를 통해 공급되는 전원전류의 전류값을 달리하여 출력하게 된다.The controller 20 to which the two types of binary signals are input temporarily stores the data in the memory 30, and then calculates the data of the binary signals according to a command set in the memory 30. Analyze whether the sunlight (a) irradiated to the rear of the vehicle (A) affects the driver of the rear vehicle (B), and in response to the output data calculated in this way of the power current supplied through the brake switch (S1) Outputs with different current value.
이와 같이 콘트롤러(20)에서 출력되는 전원전류를 제공받은 제동등(LP1, LP2)은 차후방에 조사되는 태양광(a)의 고도와 측도에 대응하는 광도로 점등하게 된다.As such, the braking lamps LP1 and LP2 provided with the power current output from the controller 20 are turned on at an intensity corresponding to the altitude and the measure of the sunlight a emitted from the rear.
따라서, 본 발명은 차량의 후방에 조사되는 태양광의 영향이 크게 되면 제동등은 더 높은 광도로 점등하게 되고, 차량의 후방에 조사되는 태양광의 영향이 적게 되면 제동등은 낮은 광도로 점등하게 되므로 후방운전자로 하여금 전방차량의 제동여부를 오판하지 않게 하여 안전운전하도록 하는 효과가 있다.Therefore, in the present invention, when the influence of sunlight irradiated to the rear of the vehicle is large, the brake light is turned on at a higher brightness, and when the influence of sunlight irradiated on the rear of the vehicle is less, the brake light is turned on at a lower brightness, so as a rear driver. There is an effect to make the driving safe by preventing the wrong vehicle braking of the front vehicle.
