Description
본 발명은 자동차용 도로에서 과속을 방지하도록 하거나, 커브길 등의 위험한 지역임을 경고하기 위한 장형 경광등에 관한 것으로서, 보다 상세하게는 별도의 외부 전력 없이 태양전지를 이용하여 발생된 전기에너지를 사용하여 발광 및 동작을 수행하는 장형 경광등에 관한 것이다. The present invention relates to a long warning light to prevent overspeed in a road for automobiles or to warn that a dangerous area such as a curve road, and more specifically using electric energy generated using a solar cell without a separate external power The present invention relates to a long warning lamp that performs light emission and operation.
종래의 경광등은 주로 경찰차의 상측에 결합되어 사용되어 왔으며, 최근에는 고속도로 또는 국도 등의 과속 우려지역, 급커브 구간, 낭떠러지 구간 등의 위험 지역에서 운전자의 주의를 환기시키기 위해 가로등 또는 기둥에 부착하여 사용되고 있다.Conventional warning lights have been mainly used in conjunction with the upper side of police cars, and recently, they are attached to street lamps or poles to call the driver's attention in dangerous areas such as speeding areas such as highways or national roads, sharp curve sections, and cliff sections. It is used.
이러한 일반적인 경광등의 사용례 및 경광등의 구성이 도 1 및 도 2에 도시되어 있다. 도 1 및 도 2를 참조하면, 장형 경광등(120)은 일반적으로 도로 가로등(110)의 일정 높이에 수평하게 결합되어 있다.Examples of the use of such a general warning light and the configuration of the warning light are shown in FIGS. 1 and 2. 1 and 2, the long warning lamp 120 is generally horizontally coupled to a predetermined height of the road street light 110.
이러한 장형 경광등(120)은 그 내부의 일면에 회전 가능한 반사판(126)을 구비한 발광램프(124)가 4개 내지 6개가 일렬로 배치되어 있고, 그 외부에는 빨간색, 파란색 등으로 된 합성수지 재질의 케이스(122)가 감싸고 있다. 케이스(122)는 반투명 재질이며, 발광램프(124)로는 주로 크세논 가스를 포함하는 램프를 사용한다.The long warning lamp 120 has four to six light emitting lamps 124 having a rotatable reflecting plate 126 on one surface thereof in a row. The case 122 is wrapped. The case 122 is a translucent material, and the light emitting lamp 124 uses a lamp mainly containing xenon gas.
장형 경광등(120)은 야간에 점등되어 반사판(126)이 회전함에 따라 반짝반짝거리게 되어 도로상의 운전자의 주의를 환기시키는 기능을 한다. 이러한 장형 경광등(120)의 구동을 위해 외부로부터 전선을 연결하거나 배터리를 이용한 전원을 사용하였다.The long warning light 120 is turned on at night, and the reflecting plate 126 is rotated to glisten as a function of alerting the driver on the road. For driving the long beacon 120, a wire was connected from the outside or a power source using a battery was used.
따라서 장형 경광등(120)에 지속적인 전력을 공급하기 위해서는, 전선을 도로변까지 끌어 들이거나, 주기적으로 배터리를 공급해 주어야만 했다. 이러한 방식은 관리가 불편할 뿐만 아니라, 설치시에 전력선을 구비하거나, 배터리를 주기적으로 교체해 주어야 한다는 번거로운 점이 발생하게 된다. 이에 별도의 전력선, 배터리에 대한 고려 없이도, 장형 경광등의 구동을 위해 반영구적인 전력 공급을 하여야 할 필요성이 대두되고 있다.Therefore, in order to supply continuous power to the long warning light 120, it was necessary to pull the wire to the side of the road, or to periodically supply the battery. This method is not only inconvenient to manage, but also has the inconvenience of having to install a power line or periodically replace the battery. Accordingly, there is a need to provide a semi-permanent power supply for driving long beacons without considering additional power lines and batteries.
종래에 가로등이나, 램프가 한 개인 경광등 등에 반영구적인 전력 공급을 위해 태양전지를 이용한 예가 있으나, 본 발명의 분야인 장형 경광등에는 아직까지 태양전지를 적용한 례가 없는바, 본 발명은 장형 경광등에도 태양전지를 적용하여 상기한 문제를 해결하고자 한다.Conventionally, there is an example in which a solar cell is used to supply semi-permanent power to a street lamp or an individual lamp such as a single lamp, but there is no case where a solar cell is not applied to a long warning lamp, which is the field of the present invention. The above problem is solved by applying a battery.
