본 발명은 태양전지에 의한 전자발광에 의해 도로의 야간식별 기능이 증진된 도로표시판에 관한 것으로 야간식별 기능을 갖게 해줌으로서 도로표시의 인식 속도를 빠르게 하여, 야간에 길을 쉽게 찾을 수 있음을 물론 도로 표시판의 심미성을 향상시킬 수 있는 태양전지가 내장된 발광기능을 갖는 도로 표시판에 관한 것이다.The present invention relates to a road display board having a nighttime identification function of a road improved by electroluminescence by solar cells, thereby enabling a nighttime identification function to speed up the recognition of road markings, making it easy to find a road at night. The present invention relates to a road display panel having a light emitting function with a built-in solar cell capable of improving the aesthetics of the road display panel.

통상의 도로표지판은 철판 등 또는 기타 판재를 이용하여 건물 및 방향을 표시하여 사용되는 판재형으로 사용되어 지고 있으며 이는 야간의 경우 거의 도로표지판으로서의 기능을 할 수 없는 실정으로 보행자에게는 거의 쓸모가 없다고 볼 수 있으며, 차량운행자의 경우도 원거리에서의 식별은 크게 곤란한 실정이다. 또한 일부의 외국의 경우 입체형으로 사용되는 경우 지하배선을 이용하여 전원을 공급하여 야간에 발광하도록 하는 방법을 사용하고 있다. 이 경우 지하의 전선용 배관의 설치와 보수 시의 도로의 굴삭 및 복토 시에 야기되는 과잉 경비 및 통행자의 불편 등을 야기하므로 시설물 공사 이전 보수 등에 있어 크게 제한을 받고 있으며, 전기에너지 사용에 따른 경제성에 있어 일부나라를 제외하고는 사실상 거의 사용이 확장되지 못되고 있는 실정이다. 또한 이 경우 지진 또는 교통사고시 등에 배선 부의 누전에 따른 사고의 방지를 제어하기가 쉽지 않아, 많은 나라가 이런 방식의 직접적인 전원 공급에 의한 입체형의 도로 표시기를 채택하지 못하고 있다.Conventional road signs are used in the form of plates used to display buildings and directions by using steel plates or other plates, which are almost useless at pedestrians at night. In addition, even in the case of a vehicle operator, it is very difficult to identify at a distance. In addition, in some foreign countries, when used in a three-dimensional form, it uses a method of supplying power by using underground wiring to emit light at night. In this case, it causes excessive expenses incurred during excavation and cover of the road during the installation and repair of underground electric pipes, and inconveniences for passengers. In fact, except for some countries, virtually no use has been extended. In addition, in this case, it is not easy to control the prevention of accidents due to leakage of the wiring part during an earthquake or traffic accident, and many countries do not adopt a three-dimensional road indicator by direct power supply in this manner.

이와 같은 문제점을 해결하기 위해 최근에는 도로표지판에 직접으로 조명을 조사하기위해 지상에 대해 45도의 각도로 기울어져 있으며 일조량을 높히기 위해 비교적 높은 위치시킨 평판형 솔라 셀에 의한 발전을 통해 축전지의 재충전에 의한 야간 가로등의 조명으로 이용하여 도로의 조명 및 도로표지판의 식별에 도움이 되도록 하는 경우가 늘고 있으나 이런 경우 넓은 평판형의 형상과 크기를 가지므로 다른 시설물에 대한 일조권 및 조망방해가 문제가 되며 또한 이 경우 복잡한 시가지 등에 설치할 경우 건물 등에서 추락하는 낙하물 등에 의해 솔라 셀 부분이 쉽게 파손될 수 있음으로 도심을 피한 비교적 한적한 공원이나 인적이 드문 시골 등에 만 적용이 가능한 단점이 있어 도로 표지판으로의 범용성에는 문제가 많다.In order to solve such a problem, in recent years, it is inclined at an angle of 45 degrees with respect to the ground to directly illuminate the road sign and recharges the battery through power generation by a relatively high-positioned flat panel solar cell to increase the amount of sunshine. Increasingly, it is used to illuminate the street lamps at night, which helps to identify road lights and road signs. However, in this case, since it has a wide flat shape and size, the sunshine and the disturbance of other facilities become a problem. In this case, the solar cell part can be easily damaged by falling objects falling from buildings, etc., when it is installed in a complicated urban area, so it can be applied only to a relatively secluded park or a small rural area avoiding the city, so there is a problem in the generality as a road sign. many.

본 발명의 과제는 도로 표지판을 야간에 쉽게 인식하고 도로 표지판의 설치 및 보수 등의 작업이 용이하도록 발명하여 기존의 도로 표지판 위치 설치함으로서 기존의 편판형의 단점인 야간 식별곤란을 완전히 해결하고, 최근에 한적한 곳 등에서만 설치가 고려되고 있는 평판형 대형 솔라 셀의 단점인 일조권 및 조망방해 등의 문제를 해결할 수 있을 뿐만 아니라, 반원형으로 볼록 렌즈를 배열하기 때문에 태양의 궤도에 거의 무관하게 많은 양의 태양 빛을 솔라 셀에 집적할 수 있으며, 집광용 렌즈가 반원형으로 설치되어 낙하물의 추락에 의한 솔라 셀의 보호기능을 가짐과 동시에 먼지 빗물 등의 적층에 의한 솔라 셀의 오염을 방지할 수 있어 장기간의 사용 후에도 본 도로 표시판은 항상 청결함이 유지되도록 하여 기존의 평판형 솔라 셀 태양에너지 지니고 있던 단점을 해결하고자 하는 것이다.The problem of the present invention is to easily recognize the road sign at night and to facilitate the installation and maintenance of the road sign to install the existing road sign location to completely solve the problem of night identification, which is a disadvantage of the conventional flat plate, It can solve problems such as sunshine and view disturbance, which are disadvantages of large flat solar cells, which are only considered to be installed in a secluded place, etc. Solar light can be integrated into the solar cell, and a condenser lens is installed in a semi-circular shape to protect the solar cell from falling objects and prevent contamination of the solar cell by lamination of dust and rain. Road signs remain clean even after use of conventional flat panel solar cell solar energy. It is to solve the shortcomings that it had.
