본 발명은 엘이디(Light Emitting Diode; 이하 "LED"라 한다.) 가로등에 관한 것으로, 더욱 상세하게는 LED의 장착 기구면에 경사각을 형성시킴으로써 측면 조도를 강화할 수 있도록 하고 열전도율을 좋게 하여 LED의 조도 향상 및 수명연장을 이끌어낼 수 있도록 하며 유지보수의 용이성을 제공할 수 있도록 한 경사각을 이용한 LED 가로등에 관한 것이다.The present invention relates to a LED (Light Emitting Diode (hereinafter referred to as "LED")) street light, and more particularly, by forming an inclination angle on the surface of the mounting mechanism of the LED to enhance the side roughness and improve the thermal conductivity of the LED illuminance The present invention relates to an LED street light using an inclination angle that can lead to improvement and life extension and to provide easy maintenance.

일반적으로 가로등은 거리의 조명이나 교통의 안전을 위하여 보도나 차도를 따라 설치한 조명시설을 말한다.In general, street lamps are lighting facilities installed along sidewalks or roadways for street lighting or traffic safety.

이러한 가로등은 종래 수은등이나 형광등 또는 나트륨등 등을 광원으로 하는 램프를 조명기구물에 장착하되 전원공급장치에 의한 전원공급과 타이머 및 중앙제어에 의한 작동으로 점등되게 함으로써 가로등이 설치된 인접지역을 일정 조도 이상으로 밝혀줄 수 있도록 하고 있으며, 최근에는 소비전력이 적게 소요되고 반영구적인 수명의 특성을 갖는 LED를 조도 향상 및 소비전력 절감의 차원에서 가로등의 광원으로 많이 적용하고 있다.Such street lights are equipped with a lamp, which is a mercury lamp, a fluorescent lamp, or a sodium lamp, as a light source to a lighting fixture, but the lamp is turned on by a power supply, a timer, and a central control operation. In recent years, LEDs, which consume less power and have a semi-permanent lifespan, have been applied as a light source for street lights in order to improve illumination and reduce power consumption.

현재 가로등의 설치기준에 의하면, 도 1의 실시예에서 보여주는 바와 같이, 가로등(1)이 지상으로부터 높이 10m 지점에 설치되는 경우 가로등이 설치되는 직선상 지면의 (A)지점에서 좌우측 10m 떨어진 지면의 (B), (C)지점에 발생되는 측면 조도가 20Lux까지 발광되어야 한다.According to the current installation standard of the street light, as shown in the embodiment of Figure 1, when the street light (1) is installed at a height of 10 meters from the ground of the ground 10m from the left and right 10m from the point (A) of the straight ground where the street lamp is installed The side illuminance generated at points (B) and (C) should emit up to 20 Lux.

하지만, 최근에 가로등의 광원으로 많이 적용되고 있는 LED는 소비전력 및 빛의 밝기 측면에서는 다른 광원에 비해 우수성을 가지나, 직선광원이 많이 나오는 특성을 갖는 것인데 단순히 반원이나 구형상의 기구물에 장착 사용하므로 인하여 측면으로 가는 광원의 차단이 발생하는 등 상기한 (B),(C)지점의 측면 조도를 20Lux까지 맞추기에 상당한 어려움이 있으며, 기존에 적용되고 있는 LED 가로등은 고장이 발생되는 경우 LED 장착용 기구물을 통째로 교체하여야 하고 실제 사용이 가능한 장착 LED까지 폐기하여야 하므로 유지보수비용이 많이 소요되는 문제점이 있었다.However, LEDs, which are recently applied as a light source for street lights, have superiority to other light sources in terms of power consumption and light brightness, but have a characteristic of generating a lot of linear light sources. There is considerable difficulty in adjusting the side illuminance of the above-mentioned (B) and (C) points to 20 Lux, such as blocking of the light source going to the side, and the existing LED street light is a fixture for LED mounting when a failure occurs. There was a problem in that the maintenance cost is high because the whole must be replaced and the mounting LED which can be actually used must be discarded.

본 발명은 상기한 문제점 등을 감안하여 창출된 것으로서, 그 목적으로 하는 바는 LED의 장착 기구면에 경사각을 형성시켜 측면 조도를 멀리 보낼 수 있도록 함으로써 LED광원의 사용 효율성을 높일 수 있도록 하고, 열전도율을 좋게 하여 LED의 조도 향상 및 수명연장을 이끌어낼 수 있도록 하며, 장착된 LED광원의 부분별 교체를 가능하게 함으로써 유지보수를 용이하게 수행할 수 있도록 하는 경사각을 이용한 LED 가로등을 제공하는데 있다.The present invention has been made in view of the above problems, and the object of the present invention is to form an inclination angle on the surface of the mounting mechanism of the LED so that side illuminance can be transmitted to increase the use efficiency of the LED light source, and thermal conductivity In order to improve the illuminance and extend the life of the LED by improving the quality, and to provide a LED street lamp using the inclination angle to facilitate the maintenance by enabling the replacement of each part of the mounted LED light source.

상기와 같은 목적을 달성하기 위한 본 발명은 LED를 이용한 가로등에 있어서, 4각형태의 볼록몸체로 상기 볼록몸체의 중심평면을 제외한 나머지 4면을 경사면으로 일체 구성하고 상기 볼록몸체의 측면에는 광원장착용 기구물에 쉽게 설치 가능하도록 체결부가 구비된 다면프레임과; 상기 다면프레임의 각 면에 체결 조립되고 각각 분리 가능한 조각기판이며 다수 사용되는 LED광원의 전기적인 연결을 위한 연결회로패턴이 형성된 광원장착기판과; 상기 광원장착기판에 다수가 장착되며 둘 이상의 LED개체가 직렬로 조합된 하나의 제1LED군과 또 다른 하나의 제2LED군을 병렬로 연결시키는 직렬과 병렬이 병합된 연결구조를 갖는 LED광원으로 이루어지는 것을 그 기술적인 기본 특징으로 한다.The present invention for achieving the above object in the street lamp using the LED, the convex body of the four-shape convex body consisting of the remaining four surfaces except the center plane of the convex body and the light source is mounted on the side of the convex body A multi-faceted frame provided with a fastening part so that it can be easily installed in the apparatus; A light source mounting substrate which is fastened and assembled on each side of the multi-faceted frame and is a separate engraving substrate, and has a connection circuit pattern for electrical connection of a plurality of LED light sources; A plurality of LED light sources are mounted on the light source mounting substrate and have a connection structure in which a series and a parallel merged structure are connected to connect one first LED group in which two or more LED objects are combined in series and another second LED group in parallel. The technical basic features.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하면서 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2 내지 도 7에 나타낸 바와 같이, 본 발명에 의한 경사각을 이용한 LED 가로등(100)은 4각형태의 볼록몸체(111)로 상기 볼록몸체(111)의 중심평면(a)을 제외한 나머지 4면을 10~40도의 경사각을 갖는 경사면(b,c,d,e)으로 일체 구성하고 상기 볼록몸체(111)의 측면에는 광원장착용 기구물(101)에 쉽게 설치 가능하도록 체결부(112)가 구비된 다면프레임(110)과, 상기 다면프레임(110)의 각 면에 체결 조립되고 각각 분리 가능한 조각기판이며 다수 사용되는 LED광원의 전기적인 연결을 위한 연결회로패턴이 형성된 PCB타입 광원장착기판(120)과, 상기 광원장착기판(120)에 다수가 일정간격으로 장착 배열되며 직렬과 병렬이 병합된 연결구조로 연결 구비되는 LED광원(130)과, 상기 다면프레임(110)의 배면 중심에 위치하여 다면프레임(110)의 표면온도를 감지하도록 장착되며 일정온도 이상이 감지되면 상기 LED광원(130)에 흐르는 전류를 낮추어 LED광원(130)의 열화를 방지하는데 사용하기 위한 온도센서(140)를 포함하는 구성으로 이루어진다.As shown in Figures 2 to 7, the LED street light 100 using the inclination angle according to the present invention is a four-sided convex body 111 of the remaining four surfaces except the center plane (a) of the convex body 111 Is formed integrally with the inclined surfaces (b, c, d, e) having an inclination angle of 10 to 40 degrees, and the fastening portion 112 is provided on the side surface of the convex body 111 so that it can be easily installed on the light source mounting mechanism 101. Multi-faceted frame 110 and PCB-type light source mounting substrate 120 is formed by connecting to each side of the multi-faceted frame 110, each of the separate engraving substrate and the connection circuit pattern for the electrical connection of a plurality of LED light source used And a plurality of LED light sources 130 mounted on the light source mounting substrate 120 at predetermined intervals and connected in a connection structure in which a series and a parallel are merged, and located at the rear center of the multi-faceted frame 110. It is mounted to detect the surface temperature of the multi-faceted frame 110 and constant When the temperature abnormality is detected, the current flowing through the LED light source 130 is made to include a configuration including a temperature sensor 140 for use in preventing degradation of the LED light source 130.

이때, 상기 다면프레임(110)과 광원장착기판(120)에는 각각 상호 대응되는 위치에 체결공(113)(120a)이 형성되며, 이를 통해 볼트 및 너트 등의 체결부재(150)에 의한 상호 조립이 가능하도록 구성되게 한다.At this time, the multi-face frame 110 and the light source mounting substrate 120 is formed with fastening holes 113, 120a at positions corresponding to each other, through which mutual assembly by fastening members 150 such as bolts and nuts. Make this possible.

상기 다면프레임(110)의 경사면(b,c,d,e)에 대하여 10~40도의 경사각을 형성시키는 이유는 직진성의 특성을 갖는 LED광원(130)의 빛을 측면으로 분산하여 조명할 수 있도록 함으로써 측면 조도를 멀리 보낼 수 있도록 하기 위함인데, 여기서 10도 미만으로 경사각을 형성할 경우 LED광원의 빛을 보낼 수 있는 측면거리가 좁아지고 측면 조도 또한 낮아지게 되며, 40도 이상으로 경사각을 형성할 경우 LED광원의 빛을 보낼 수 있는 측면거리가 넓어지기는 하나 측면 조도가 떨어지게 된다.The reason for forming the inclination angle of 10 to 40 degrees with respect to the inclined surfaces b, c, d, and e of the multi-faceted frame 110 is to distribute the light of the LED light source 130 having the characteristic of straightness to the side to illuminate This is to allow the side illuminance to be sent away. If the inclination angle is formed below 10 degrees, the side distance for transmitting the light of the LED light becomes narrow and the side illuminance is also lowered. In this case, although the side distance for transmitting the light of the LED light becomes wider, the side illuminance is reduced.

상기 다면프레임(110)의 경사면(b,c,d,e)은 20도의 경사각을 형성함이 가장 바람직하다.It is most preferable that the inclined surfaces b, c, d, and e of the multifaceted frame 110 form an inclination angle of 20 degrees.

또한, 상기 다면프레임(110)은 열전도율을 좋게 하기 위하여 알루미늄(Al) 재질 또는 열전도성 플라스틱 중에서 선택된 어느 하나를 적용토록 함이 바람직하며, 그 유형은 전반적으로 5면을 갖는 4각형태로 설명하고 도시하였으나 이에 한정된다 할 수 없으며 육면 및 팔면으로의 구성 등 다면구조로의 치환 및 변경 실시가 가능하다 할 것이다.In addition, the multi-faceted frame 110 is preferably applied to any one selected from aluminum (Al) material or thermally conductive plastic in order to improve the thermal conductivity, the type is described as a quadrangular shape having a five-side overall. Although not shown in the drawing, the present invention is not limited thereto, and the substitution and modification to a multi-faceted structure, such as a six-sided and eight-sided configuration, may be possible.

상기 광원장착기판(120)은 알루미늄재질 또는 열전도성 플라스틱의 베이스판(121)과, 상기 베이스판(121)의 상면에 구비되며 LED 연결용 회로패턴이 형성된 에폭시재질의 회로패턴층(122)과, 상기 베이스판(121)의 후면에 열전도율 향상을 위해 코팅되는 도전성 접착제에 의한 도전층(123)과, 상기 회로패턴층(122)의 상면에 구비되며 방수 및 방습기능을 부여하기 위한 실리콘재질의 방수층(124)으로 구성되게 한다.The light source mounting substrate 120 includes a base plate 121 made of aluminum or a thermally conductive plastic, an epoxy circuit circuit layer 122 formed on an upper surface of the base plate 121, and a circuit pattern for connecting LEDs is formed.
