Description

교통표지판{The TRAFFIC SIGN BOARD}Traffic Signs {The TRAFFIC SIGN BOARD}

본 발명은 LED를 사용한 면발광 교통표지판에 관한 것으로, 특히 도로의 교통표지판을 구성하는 문자표시부와 방향표시부를 구획하여 각각으로 발광토록 함으로서 원가를 절감하면서도 전기가 없는 지역에서도 솔라셀에 의한 설치가 가능함은 물론 수선 또한 용이토록 한 것이다.The present invention relates to a surface-emitting traffic sign using LED, and in particular, by separating the character display section and the direction display section constituting the traffic sign of the road to emit light by each of the installation by the solar cell even in the area without electricity while saving cost Not only is it possible, but it is also easy to repair.

현재 도로를 운전하다보면 길을 안내하거나 또는 방향을 안내하는 교통표지판을 보게 되는데 이러한 교통표지판이 대부분 그 넓이가 작은것이 3000㎜×2000㎜이고, 중형의 것이 5000㎜×2250㎜에 해당되기 때문에 대부분 알루미늄플레이트에 고휘도 반사지를 다층으로 중첩하여 다양한 색상으로 구현토록 하고 있는 것이다.If you are driving on a road, you will see traffic signs that guide you or guide you in the direction. Most of these traffic signs are 3000mm × 2000mm in width and medium in size are 5000mm × 2250mm. High brightness reflective paper is superimposed on aluminum plate in multiple layers to realize various colors.

따라서 반드시 광원이 있어야만 빛을 반사하고, 일한 교통표지판은 지면에서 일정하 높이의 위치에 매달리는 것이기 때문에 운전자들은 주로 야간에 교통표지판을 확인하기 위하여는 상향등을 키면서 확인하거나 또는 가까지 접근한 상태에서 확인이 가능하기 때문에 이럴 경우에는 급하게 방향을 바꿔야 되는 위험한 상황을 경험하게 되는 것이다.Therefore, the light source must reflect the light, and the working traffic signs are suspended at a certain height from the ground. Therefore, drivers usually check the traffic lights at night or turn on the vehicle to check the traffic signs at night. Because you can see it, you're going to experience a dangerous situation where you have to change direction quickly.

따라서 전원을 이용하여 야간에도 식별이 가능한 교통표지판이 제안되고 있으나 그중의 하나가 교통표지판의 외측에서 써치라이트를 사용하여 교통표지판의 전면에 표시된 내용을 비춰주게 되는 것이다.Therefore, a traffic sign that can be identified at night by using a power source has been proposed, but one of them is to use the searchlight on the outside of the traffic sign to illuminate the content displayed on the front of the traffic sign.

그러나 이러한 써치라이트의 형태는 잦은 전등의 훼손에 의하여 유지보수비가 많이 소요된다는 단점은 물론 이러한 써치라이트가 교통표지판을 가리게 됨으로서 실질적인 사용이 불가능하다는 것이다.However, the form of the searchlight is a disadvantage that the maintenance cost is high due to frequent damage to the lamp, as well as that such a searchlight cover the traffic sign is practically impossible to use.

따라서 최근에는 전광판의 형태로 제안되는 것이 있으나 이러한 것의 단점은 가까운 곳에서는 방향표시부나 문자표시부의 내용을 선명하게 확인이 불가능하다는 단점이 있고 특히 주간에서는 사용이 불가능함으로 이러한 것도 실질적인 교통표지판에서는 사용이 불가능한 것이다.Therefore, in recent years, there have been proposals in the form of electronic signs, but the disadvantage of this is that it is impossible to clearly check the contents of the direction display part or the character display part in the near area, and in particular, it is impossible to use it in the daytime, so this is also practically used in traffic signs. It is impossible.

따라서 최근에는 백라이트를 사용하여 주간과 야간에 동시 사용이 가능토록 한 것이 제안되고 있으나 이러한 것은 많은 전등을 사용함은 물론 이러한 전등의 훼손에 따른 유지보수가 곤란하여 실질적인 사용이 불가능하다는 것이다.Therefore, in recent years, it has been proposed to use the backlight at the same time day and night, but this is not only use a lot of lights, but also difficult to maintain due to the damage of these lights, practical use is impossible.

따라서 최근에는 백라이트의 대용으로 LED모듈을 사용한 것이 제안되고 있으나 이러한 것의 단점은 LED모듈에서 발생되는 빛이 직진성이 강하여 일정거리가 이격되어져야 함으로 이럴 경우에 교통표지판의 두께가 두꺼워져 실질적인 사용이 불가능한 단점이 있고, 많은 LED모듈의 사용은 제작단가가 상승은 물론 이러한 LED모듈의 어느 하나의 LED가 훼손될 경우에 모든 것을 교환하여야 한다는 단점이 있어 이것도 실질적인 사용이 되지 못하고 있는 것이다.Therefore, in recent years, it is proposed to use the LED module as a substitute for the backlight, but the disadvantage of this is that the light generated from the LED module has a strong straightness and should be spaced apart by a certain distance. In this case, the thickness of the traffic sign becomes thick and practical use is impossible. There are disadvantages, and the use of a large number of LED modules, as well as the manufacturing cost increases, if any one of the LED module is damaged, there is a disadvantage that all must be replaced, which is also not practical use.

따라서 본 발명에서는 LED모듈을 사용하여 저전력이 소모토록 하면서 주야구분이 가능하고, 면발광이 가능토록 함은 물론 간단하게 유지보수 또한 용이토록 함은 물론 전기가 공급되지 않은 곳에서도 태양광에 의하여 간단하게 설치가 가능토록 한 것이다.Therefore, in the present invention, the LED module can be used to distinguish between the day and night while consuming low power, allowing surface light emission, as well as easy maintenance, and also simple by sunlight even when no electricity is supplied. It is possible to install it.

이를 위하여 빛을 투과토록 하는 메인보드의 전방에 방향표시부나 문자표시부가 형성된 후방에 방향표시부나 문자표시부로 구획하여 측변에 장착된 LED모듈이 장착된 도광판을 장착하고, 그 후방으로는 도광판의 빛이 전방으로만 주사토록 반사지를 형성하고, 그 후방으로는 메인보드와 일체로 형성되게 결합되는 덮개판이 형성되도록 한 것이다.To this end, a light guide plate equipped with an LED module mounted on the side by dividing it into a direction display unit or a letter display unit at the rear of the main board through which light is transmitted is formed, and a light guide plate mounted thereon. The reflective sheet is formed to be scanned only in the front side, and the cover plate is formed at the rear thereof to be integrally formed with the main board.

또한 LED램프의 점멸을 단속하는 콘트롤모듈을 사용하여 방향표시부의 형태가 표시된 방향으로 점멸이 이루어지도록 함으로서 좀더 명확한 방향을 표시토록 하는 것이다.In addition, by using the control module to control the blinking of the LED lamp to make the direction of the display part blinks in the indicated direction to display a more clear direction.

또한 솔라셀을 장착하여 콘트롤러에 의한 충전기에의 저장과 야간에 점등이 이루어지도록 함으로서 전기가 공급되지 않는 오지에서도 사용이 가능토록 한 것이다.In addition, the solar cell is installed in the charger by the controller and the lighting is made at night so that it can be used even in remote areas without electricity.

따라서 LED모듈이 교통표지판의 부분적으로 장착되어짐으로서 저비용과 저전력이 사용되어지고, 또한 고장이 발생될 경우에 부분적으로 교환토록 함으로서 수선또한 용이하게 되는 것이다.Therefore, the low cost and low power are used because the LED module is partially mounted on the traffic sign, and it is also easy to repair by partially replacing when a failure occurs.

또한 이로 인하여 대형의 교통표지판에도 적용이 가능함으로 다양한 용도로의 사용이 가능하게 되는 것이다.In addition, it can be used for a large number of traffic signs because it can be applied to large traffic signs.
