통상 도로나 공사현장에서 통행금지 또는 차선변경 표시를 할 때 사용되는 싸인장치는 단일 색상으로 된 복수개의 엘이디가 일정한 형태로 배열되어 주위에 정보를 제공하도록 구성된다.Sign devices, which are usually used to indicate curfew or lane change signs on roads or construction sites, are configured to provide information around a plurality of LEDs in a single color arranged in a uniform fashion.

그러나, 종래의 엘이디 등기구는 단일 색상으로 구성되어 주간이나 야간 또는 안개가 낀 흐린 날씨에 상관없이 늘 동일한 색상을 제공하는 것으로서, 변화하는 주변 날씨와 시간대에 따라 그 밝기의 편차가 심각한 단점이 있었다.However, conventional LED luminaires are composed of a single color to provide the same color regardless of daytime, nighttime, or foggy cloudy weather, and there is a serious disadvantage in the brightness variation according to changing ambient weather and time zone.

따라서, 본 발명은 상기와 같은 점을 고려하여 안출된 것으로서, 상황에 따라 적색과 황색 중 한가지 색상만 선택적으로 점등되거나 필요시 두가지 색상이 동시에 점등되도록 하여 일기에 관계없이 최적의 밝기를 유지할 수 있도록 구성되는 이중 점등 엘이디 등기구를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in consideration of the above points, and depending on the situation, only one color of red and yellow may be selectively lit or two colors may be simultaneously lit when necessary to maintain optimal brightness regardless of weather. It is an object to provide a double-lit LED luminaire that is configured.

상기와 같은 목적을 달성하기 위한 본 발명의 이중 점등 엘이디 등기구는, 복수개의 단위램프로 이루어지는 엘이디(LED) 싸인장치에 있어서, 상기 단위램프는, PCB 위에 복수개의 적색과 황색 엘이디를 교차시켜 균일하게 배열하여 줌으로써, 제어기를 통해 두가지 색상 중 단일색의 엘이디를 선택적으로, 또는 이들을 동시에 점등하여 주황빛을 발하게 한 것을 특징으로 한다.The double-lit LED luminaire of the present invention for achieving the above object, in the LED sign device consisting of a plurality of unit lamps, the unit lamps, by crossing a plurality of red and yellow LEDs on the PCB uniformly By arranging, LEDs of a single color of two colors are selectively or lit simultaneously through the controller to emit orange light.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명이 적용되는 싸인장치를 도시한 사시도이고, 도 2는 본 발명 의 엘이디(LED)가 장착된 단위램프를 도시한 사시도이고. 도 3은 도 2의 측단면도이고, 도 4a 내지 도 4c은 본 발명의 일실시예로 단위램프에 엘이디가 방사상 형태로 배열된 것을 도시한 정면도이고, 도 5a 내지 도 5c는 본 발명의 다른 실시예로 단위램프에 엘이디가 바둑판 형태로 배열된 것을 도시한 정면도이다.1 is a perspective view showing a sign apparatus to which the present invention is applied, and FIG. 2 is a perspective view showing a unit lamp to which an LED of the present invention is mounted. Figure 3 is a side cross-sectional view of Figure 2, Figures 4a to 4c is a front view showing the LED is arranged in a radial form in the unit lamp as an embodiment of the present invention, Figures 5a to 5c is another embodiment of the present invention For example, it is a front view showing that LEDs are arranged in a checkerboard shape on a unit lamp.

도 1에 도시된 바와 같이, 본 발명의 엘이디 등기구는 일반적으로 도로나 공사현장에서 경고 또는 방향 표시를 하기 위해 사용되는 싸인장치에 적용되는 점등식 표시기구이다.As shown in Figure 1, the LED luminaire of the present invention is a lighted display mechanism that is generally applied to a sign used for warning or direction indication on the road or construction site.

이러한 싸인장치는 복수개의 단위램프(100)가 통행금지를 표시하는 'x' 또는 이동방향을 표시하는 '↘', '↙'와 같이 상황에 맞게 적합한 정보 표시를 할 수 있도록 전면에 배치된 것으로, 상기 단위램프(100)는 도 2 및 도 3에 도시된 바와 같이, 복수개의 엘이디(30)(40)가 장착된 PCB(20)를 지지하는 플레이트(15)와, 상기 엘이디(30)(40)의 빛이 주변으로 파상되는 것을 막아 전면에서의 식별력을 향상하도록 상기 플레이트(15) 둘레에 설치되는 커버(10)로 구성된다.Such a sign device is disposed on the front of the plurality of unit lamps 100 to display information appropriate to the situation, such as 'x' indicating a curfew or '↘', '↙' indicating a moving direction. 2 and 3, the unit lamp 100 includes a plate 15 supporting the PCB 20 on which the plurality of LEDs 30 and 40 are mounted, and the LEDs 30 ( It is composed of a cover 10 installed around the plate 15 to prevent the light of the 40 to be broken around to improve the discriminating power in the front.

이때, 상기 엘이디(30)(40)는 약 Φ180mm 정도의 크기를 갖는 100-200개의 적색LED(30)와 황색LED(40)가 PCB(20) 위에 교차되며 균일하게 배열된 것으로, 본 실시예에서는 도 4a 내지 도 4c에 도시한 바와 같이 방사상 형태의 배열이나 도 5a 내지 도 5c에 도시된 바와 같이 바둑판 형태의 배열로 설치함이 바람직하다. 단, 상기한 엘이디의 배열형태는 흔히 사용되는 배열을 예로 든 것으로, 반드시 이에 한정하는 것은 아니며, 본 발명의 기술적 사상의 범주 내에서는 얼마든지 수정 및 변형 실시가 가능하다.At this time, the LEDs 30 and 40 are 100-200 red LEDs 30 and yellow LEDs 40 having a size of about Φ 180 mm and are uniformly arranged on the PCB 20 and are uniformly arranged. In Figure 4a to 4c it is preferable to install in a radial arrangement or as shown in Figures 5a to 5c arranged in a checkerboard arrangement. However, the arrangement form of the above-described LED is an example of a commonly used arrangement, but is not necessarily limited thereto, and modifications and variations may be made within the scope of the technical idea of the present invention.

이때 상기 단위램프(100)의 엘이디(30)(40)는, 주간에는 도 4b 또는 도 5b에서와 같이 적색엘이디(30)를 선택적으로 점등하고, 안개가 낀 날씨나 야간에는 도 4c 또는 도 5c에서와 같이 황색엘이디(40)를 선택적으로 점등하며, 태양광선이 작렬하는 낮시간에는 4a 또는 5a에서와 같이 적색엘이디(30)와 황색엘이디(40)를 동시에 점등시켜 주황빛을 발하게 함으로써, 일기에 상관없이 단위램프(100)가 항상 최적의 밝기를 유지하게 된다.In this case, the LEDs 30 and 40 of the unit lamp 100 selectively light the red LEDs 30 as in FIG. 4B or 5B during the day, and in FIG. 4C or 5C in the foggy weather or at night. As shown in the yellow LED 40 and selectively lit, during the daytime when the sun's rays ignite the red LED 30 and the yellow LED 40 at the same time, such as 4a or 5a to emit orange light, Regardless, the unit lamp 100 always maintains the optimum brightness.

즉, 도 1에 도시된 바와 같이, 싸인장치 중 상기 설명한 'x' 또는 '↘', '↙'를 표시하기 위해 해당하는 위치에 설치된 각각의 단위램프(100)는 PCB(30) 후방으로 전선(50)을 통해 연결된 제어기를 이용하여 장착된 엘이디(30)(40)가 동일 색상으로 점등됨으로써, 해당 정보 표시를 일기 및 시간대에 따라 최적의 밝기로 표시하여 그 식별력을 향상시키는 것이다.That is, as shown in Figure 1, each of the unit lamps 100 installed in the corresponding position to display the 'x' or '↘', '↙' described above of the sign device is wired to the rear of the PCB (30) The LEDs 30 and 40 mounted by using the controller connected through the 50 are lighted with the same color, thereby displaying the corresponding information display at an optimal brightness according to the diary and the time zone, thereby improving its discriminating power.

이상에서 설명한 바와 같이, 본 발명의 이중 점등 엘이디 등기구는, 동일한 PCB 상에 복수개의 적색과 황색 엘이디를 교차시켜 균일하게 설치함으로써, 일기 및 시간대에 상관없이 항상 최적의 밝기를 유지하도록 하여 싸인장치의 식별력을 최대화할 수 있는 효과가 있다.As described above, the double-lit LED luminaire of the present invention is installed on the same PCB by crossing a plurality of red and yellow LEDs uniformly, so that the optimum brightness is always maintained regardless of weather and time zone. It has the effect of maximizing discernment.
