최근 조경시설 또는 건축물의 외관을 야간에 조명하거나 보도를 밝히기 위한 경관용 조명장치가 설치되어 사용되고 있다.Recently, the landscape lighting device for lighting the exterior of the landscape facilities or buildings at night or to illuminate the sidewalks has been installed and used.

이러한 경관용 조명장치 중 지중에 매립되게 설치되는 지중등은 단색 또는 다색의 광원을 이용하여 광을 출사할 수 있도록 되어 있으나, 조명분위기를 다양 하게 변화시켜주지 못하는 단점이 있다.Underground lighting installed in the ground of the landscape lighting device is to be able to emit light by using a single or multi-color light source, but there is a disadvantage that can not change the lighting atmosphere variously.

또한, 상호 다른 색의 광을 출사할 수 있도록 되어 있는 경우에도 주기적으로 표시색만 가변시킬 수 있도록 되어 있어, 규칙성에 의한 표시색 변화 패턴이 단조로운 문제점이 있다.In addition, even when it is possible to emit light of different colors, only the display color can be changed periodically, so that the display color change pattern due to regularity is monotonous.

본 발명은 상기와 같은 문제점을 개선하기 위하여 창안된 것으로서, 상호 다른 컬러광의 조합에 의해 표시되는 색패턴을 더욱 다양화할 수 있는 지중등을 제공하는 데 그 목적이 있다. The present invention has been made to improve the above problems, and an object thereof is to provide an underground lamp which can further diversify the color pattern displayed by a combination of different color lights.

본 발명의 또 다른 목적은 보는 각도에 따라 상호 다른 패턴의 표시광을 연출할 수 있도록 된 지중등을 제공하는 것이다.It is still another object of the present invention to provide an underground lamp that can produce display light having a different pattern depending on the viewing angle.

상기의 목적을 달성하기 위하여 본 발명에 따른 지중등은 입사된 광을 반사시킬 수 있는 반사면을 갖는 적어도 3개 이상의 반사판이 속이 빈 다각 공간을 형성하도록 상기 반사면이 내측에 위치되게 상호 접합된 다각 반사경과; 상호 다른 색상의 광을 출사하는 복수개의 발광다이오드가 어레이되어 상기 다각 반사경의 하부에서 상기 다각 반사경을 통해 광을 반사시킬 수 있도록 설치된 광원모듈과; 상기 다각 반사경의 상기 다각 공간을 외부에 대해 차폐되게 보호할 수 있도록 상기 다각 반사경의 상부에 설치되어 상기 다각 반사경을 통해 출사되는 광을 투과시키는 캡;을 구비한다.In order to achieve the above object, the underground light according to the present invention has at least three or more reflecting plates having reflecting surfaces capable of reflecting incident light such that the reflecting surfaces are positioned inward so as to form a hollow polygonal space. Multiple reflectors; A light source module arranged so that a plurality of light emitting diodes emitting light of different colors may be arrayed to reflect light through the polygonal reflectors below the polygonal reflectors; And a cap installed on an upper portion of the polygon reflector to transmit light emitted through the polygon reflector so as to shield the polygon space of the polygon reflector to be shielded from the outside.

바람직하게는 상기 다각 반사경은 적어도 어느 하나의 반사판이 나머지 반사 판 보다 상방으로 더 길게 연장되게 형성된다.Preferably, the polygon reflector is formed such that at least one reflector extends longer than the other reflector.

또한, 상기 다각 반사경과 상기 광원모듈을 수용하며 지중에 매립되게 설치될 수 있게 형성된 하우징;을 더 구비하고, 상기 캡은 상기 하우징의 상부에서 상기 하우징의 내부공간을 폐쇄할 수 있도록 설치된다.The apparatus may further include a housing configured to accommodate the polygonal reflector and the light source module so as to be embedded in the ground, and the cap may be installed to close the inner space of the housing from an upper portion of the housing.

본 발명의 일 측면에 따르면, 상기 캡의 내면은 입사된 광을 산란시키도록 다수의 돌기가 상호 이격되게 형성된다.According to one aspect of the invention, the inner surface of the cap is formed with a plurality of projections spaced apart from each other to scatter the incident light.

더욱 바람직하게는 상기 광원모듈과 상기 다각 반사경 중 어느 하나가 상대회전될 수 있도록 형성된다.More preferably, any one of the light source module and the polygon reflector is formed to be relatively rotated.

이하, 첨부된 도면을 참조하면서 본 발명의 바람직한 실시 예에 따른 지중등을 더욱 상세하게 설명한다.Hereinafter, the ground lamp according to the preferred embodiment of the present invention with reference to the accompanying drawings will be described in more detail.

플랜지부분(114)은 매립대상체 예를 들면 지면, 또는 그 밖의 지반구조물에 매립되게 설치될 때 결합을 위해 이용되거나, 매립상태에서의 유동성을 억제하도록 적용된 것이다.The flange portion 114 is used for bonding when installed in a buried object, for example, the ground or other ground structure, or applied to suppress fluidity in a buried state.

캡(120)은 하우징(110)의 상부에서 내부공간을 폐쇄할 수 있도록 결합되어 내부공간 내에 수납된 요소를 보호함과 아울러 광원모듈(140)에서 다각 반사경(130)을 통해 출사되는 광을 투과시킬 수 있는 투명 또는 반투명 소재로 형성된다.The cap 120 is coupled to close the inner space at the upper portion of the housing 110 to protect the elements stored in the inner space and to transmit the light emitted through the polygon reflector 130 from the light source module 140. It is made of transparent or translucent material.

도시된 예에서는 캡(120)이 하우징(110)과 나사결합에 의해 착탈할 수 있는 구조가 적용되었다.In the illustrated example, a structure in which the cap 120 is detachable by screwing the housing 110 is applied.

도시된 예와 다르게 하우징(110)이 생략되고, 다각 반사경(130) 상부에 캡이 결합되어 다각 반사경 내부의 다각 공간을 외부에 대해 차폐되게 보호할 수 있도록 구축될 수 있음은 물론이다. Unlike the illustrated example, the housing 110 may be omitted, and the cap may be coupled to the upper portion of the polygon reflector 130 to be constructed to shield the polygon space inside the polygon reflector to be shielded from the outside.

캡(120)의 내면에는 입사된 광을 산란시키기 위한 다수의 돌기(122)가 상호 이격되어 돌출되게 형성되어 있다.On the inner surface of the cap 120, a plurality of protrusions 122 for scattering the incident light is formed to be spaced apart from each other.

도시된 예와 다르게 돌기(122)는 생략될 수 있음은 물론이다.Unlike the illustrated example, the protrusion 122 may be omitted.

다각 반사경(130)은 입사된 광을 반사시킬 수 있는 반사면(131a)(132a)(133a)을 갖는 3개의 반사판(131)(132)(133)이 속이 빈 다각 공간(130a)을 형성하도록 반사면(131a)(132a)(133a)이 내측에 위치되게 상호 접합되어 있다.The polygon reflector 130 has three reflecting plates 131, 132, 133 having reflecting surfaces 131a, 132a, 133a capable of reflecting incident light to form a hollow polygonal space 130a. The reflective surfaces 131a, 132a, and 133a are bonded to each other so as to be positioned inside.

바람직하게는 다각 반사경(130)보는 각도에 따라 표시색 패턴이 달라 질 수 있도록 어느 하나의 반사판(133)이 나머지 반사판(131)(132) 보다 상방으로 더 길게 연장되게 형성된다.Preferably, the reflector 130 is formed such that one of the reflecting plates 133 extends longer than the other reflecting plates 131 and 132 so that the display color pattern may vary according to the viewing angle.

도시된 예에서는 제1 및 제2 반사판(131)(132)보다 제3반사판(133)이 더 길게 연장된 구조가 예시되었다.In the illustrated example, a structure in which the third reflector 133 extends longer than the first and second reflector plates 131 and 132 is illustrated.

이 경우 다각 반사경(130)을 거쳐 다양한 상의 조합에 의해 형성된 이미지 패턴에 대해 보는 각도에 따라 상호 다른 패턴의 색무늬를 제공할 수 있다. In this case, the color patterns of different patterns may be provided depending on the viewing angle of the image pattern formed by the combination of various images via the polygon reflector 130.

다각 반사경(130)은 도시된 예와 다르게 사각, 5각 등 적용되는 반사판의 개수가 4개 이상 적용될 수 있음은 물론이다.Unlike the illustrated example, the polygonal reflector 130 may include four or more reflecting plates to be applied, such as a square and a five-corner.

광원모듈(140)은 상호 다른 색상의 광을 출사하는 복수개의 발광다이오드(141)(142)(143)가 구동 기판(145)에 어레이되어 있다.The light source module 140 includes a plurality of light emitting diodes 141, 142, 143 that emit light of different colors from each other on the driving substrate 145.

바람직하게는 적색, 녹색 및 청색 광을 각각 출사하는 발광다이오드(141)(142)(143)가 적용되고, 각 색상별 발광다이오드(141)(142)(143)의 적용개수는 2개 이상 적용될 수 있음은 물론이다.Preferably, the light emitting diodes 141, 142 and 143 which emit red, green and blue light, respectively, are applied, and the number of applications of the light emitting diodes 141, 142 and 143 for each color is two or more.

광원모듈(140)은 다각 반사경(130)의 하부에서 다각 공간(130a)을 통해 광을 출사하되 다각 반사경(130)의 반사판(131)(132)(133)을 통해 광을 반사시킬 수 있도록 광축이 반사판(131)(132)(133)을 향하도록 경사지게 구동기판(145)에 설치되는 것이 바람직하다.The light source module 140 emits light from the lower portion of the polygon reflector 130 through the polygonal space 130a, but reflects light through the reflecting plates 131, 132, 133 of the polygon reflector 130. It is preferable that the driving plate 145 be inclined so as to face the reflecting plates 131, 132, 133.

도시된 예와 다르게 광원모듈(140)은 하우징(110) 내에 고정시키고 다각 반사경(130)이 회전되도록 구축될 수 있음은 물론이다.Unlike the illustrated example, the light source module 140 may be constructed to be fixed in the housing 110 and to rotate the polygon reflector 130.

이러한 지중등(100)을 보행로 또는 건축물의 경관 조명용으로 설치해 놓은 경우 지중등(100)을 지나가는 과정에서의 보행자의 지중등(100)에 대한 상대 위치 및 방향이 달라질 때마다 다각 반사경(130)을 경유하면서 생성되는 다양한 상의 조합에 의해 생성된 표시패턴이 달라짐으로써 시각적으로 다양하게 변화하는 패턴의 색상광을 제공할 수 있다.When the underground light 100 is installed for pedestrian or building landscape lighting, the polygon reflector 130 is changed whenever the relative position and direction of the pedestrian's underground light 100 in the process of passing the underground light 100 are changed. As the display pattern generated by the combination of various images generated while passing through is changed, it is possible to provide color light of a pattern that varies visually.

지금까지 설명된 바와 같이 본 발명에 따른 지중등에 의하면, 다각 반사경에 의해 생성되는 다양한 패턴의 색무늬를 위치 및 방향에 따라 다르게 제공하여 조명할 수 있는 장점을 제공한다.As described above, according to the underground light according to the present invention, various patterns of color patterns generated by the polygonal reflectors are provided differently according to positions and directions, thereby providing an advantage of illumination.
