Description

매트릭스형 스마트 자동차 전조등{Smart headlight of matrix type for automobile}Smart headlight of matrix type for automobile}

본 발명은 자동차 스마트 전조등에 관한 것으로서, 상세하게는 복수의 엘이디가 매트릭스 형태로 형성되어, 도로의 직선구간, 곡선구간, 경사구간 및 차량의 주행 방향, 주행 속도에 따라 운전자의 시야 확보를 위한 조명거리와 조명각도를 조절하고, 주변 차량간의 거리를 감지하여 색상, 명도, 채도, 조도, 휘도 중 적어도 1가지 이상을 변경하는 것에 의해 운전자에게 안전거리를 정확하고 안정적으로 인지시키는 차량 전조등에 관한 것이다.The present invention relates to a smart car headlight, in detail, a plurality of LEDs are formed in a matrix form, the illumination for securing the driver's field of view according to the straight section, curved section, inclined section and driving direction, driving speed of the road The present invention relates to a vehicle headlight that accurately and stably recognizes a safety distance to a driver by adjusting a distance and an angle of illumination and sensing at least one of color, brightness, saturation, illumination, and luminance by sensing a distance between nearby vehicles. .

차량의 전조등은 야간, 우천, 안개 등의 상황에서 운전자의 전방 시야 확보를 위해 사용되는 차량의 조명장치이며, 야간에는 하향등을, 안개가 발생하여 전방을 주의하며 운전해야 하는 경우에는 상향등을 사용한다.The headlight of the vehicle is the lighting device of the vehicle used to secure the driver's vision in the night, rainy weather, fog, etc. do.

차량이 직선 구간을 주행중에는 전조등의 조명이 정확하게 조사(照射)되는데 비해 곡선 구간을 주행중에는 전조등의 조명이 정확하게 조사되지 않는 사각지대가 발생하고 경사 구간에서는 조명거리가 짧아지거나 길어짐으로 인해 운전자의 시야가 불안정해지고, 반대차선의 차량에 강한 조명을 조사하여 반대차선의 차량 운전자의 전방 시야를 방해함에 따른 안전사고가 발생할 가능성이 있다.While the vehicle is traveling in a straight section, the headlights are accurately illuminated, while in a curved section, blind spots in which the headlights are not irradiated correctly are generated. Is unstable, and there is a possibility that a safety accident is caused by irradiating strong lights on the vehicle of the opposite lane and obstructing the forward view of the vehicle driver of the opposite lane.

또한, 일반적인 차량의 전조등은 운전자가 전조등이 조사하는 조명의 조도와 색상을 도로와 날씨 상황 등에 따라 변경할 수 없기 때문에 안개가 많이 낀 날씨나 폭설, 폭우 시에 전방 시야 확보가 어려우므로, 주변 차량에 자신의 차량을 인지시키거나 자신의 차량을 주변 차량이 인식하지 못해 안전거리 미확보로 인한 사고가 발생할 수도 있다. 그 밖에도 일반 전구를 적용한 전조등은 수명이 짧고 전력효율과 내구성도 우수하지 못하다는 문제가 있다.In addition, the headlight of a general vehicle cannot change the illuminance and color of the light irradiated by the headlight according to the road and weather conditions, so that it is difficult to secure a forward view in a foggy weather, heavy snow, or heavy rain. An accident may occur due to the inability to secure a safe distance because the vehicle is not recognized or the surrounding vehicle is not recognized. In addition, headlights using ordinary light bulbs have a short lifespan and have poor power efficiency and durability.

상기와 같은 문제점을 개선하기 위해 특허문헌 1, 2, 3이 제시되어 있다. 특허문헌 1은 일반 전구에 비해 수명이 길고 전력효율과 내구성도 우수한 엘이디(LED : light emitting diode)를 이용한 차량의 조명장치에 관한 것으로, 도로 상황이나 운전자의 선택에 따라 자유롭게 색상이나 밝기 등을 조절하여 안전운전을 가능하게 하고, 램프의 수명을 연장함과 아울러 조명 장치를 단순화하는 발명이다.Patent document 1, 2, 3 is proposed in order to improve the above problems. Patent Literature 1 relates to a lighting device of a vehicle using a light emitting diode (LED), which has a longer lifespan and has higher power efficiency and durability than a general light bulb, and freely adjusts color and brightness according to road conditions or driver's choice. It is an invention that enables safe operation, extends the life of the lamp and simplifies the lighting device.

특허문헌 2는 차량 전조등용 엘이디 콜리메이터 소자에 관한 것으로, 광원의 최소한 한 구역으로부터 최소한 한 가지 색의 가시광을 방출하는 하향 빔 기능을 갖는 발명이다.Patent document 2 relates to the LED collimator element for a vehicle headlight, and is an invention having a downward beam function for emitting visible light of at least one color from at least one region of a light source.

특허문헌 3은 도로 위험물에 대한 사전 경고 장치에 관한 것으로, 다가올 예기치 않은 위험물에 접근하는 주변 차량의 운전자에게 경고하기 위해 운전자에 의해 작동되는 발명이다.Patent document 3 relates to an advance warning device for road dangerous goods, and is an invention operated by a driver to warn a driver of a nearby vehicle approaching an unexpected dangerous goods to come.

하지만, 특허문헌 1과 특허문헌 2는 차량이 곡선 구간, 경사구간에 주행시 전조등의 조명거리와 조명각도를 조절하는 기능이 없어 여전히 곡선 구간, 경사구간에 주행시에 조명이 정확하게 조사되지 않는 사각지대가 발생하므로 안전사고의 위험이 있다.However, Patent Literature 1 and Patent Literature 2 do not have the function to adjust the lighting distance and the lighting angle of the headlight when the vehicle is traveling in a curved section or inclined section. There is a risk of safety accident.

또한, 특허문헌 3은 운전자가 수동으로 조작하는 구성이므로, 운전중에 정확하게 조작하기 어렵고 주변 차량이 사전 경고 장치에서 발생하는 신호를 인지하지 못하는 경우가 발생되는 문제가 있다.In addition, since Patent Literature 3 is configured to be manually operated by a driver, there is a problem in that it is difficult to accurately operate it while driving and a case in which a nearby vehicle does not recognize a signal generated by a pre-warning device.
