조명등기구가 설치되는 배선 덕트{A Wiring Duct Built-in Luminaire}Wiring duct where lighting fixture is installed {A Wiring Duct Built-in Luminaire}

본 발명은 업무용 빌딩, 학교, 지하철, 주차장, 대형매장 등의 천정에 배치하여 조명등을 쉽게 설치할 수 있게 한 조명등기구가 설치되는 배선 덕트에 관한 것이다.The present invention relates to a wiring duct that is installed on the ceiling of a business building, school, subway, parking lot, large store, etc., so that the lighting fixtures can be easily installed.

종래에도 조명등을 설치할 수 있는 배선 덕트가 개발된 바 있다.Conventionally, wiring ducts have been developed to install lighting.

이러한 배선 덕트는 지금까지 다양하게 개발되어 왔으나 그중에 하나를 소개하면 국내 특허 제10-0714420호를 들 수 있다.Such wiring ducts have been variously developed so far, but if one of them is introduced, there may be mentioned Korean Patent No. 10-0714420.

상기 종래기술은 도 1에 도시된 바와 같이 덕트 본체(80)의 양쪽에 측벽(81)이 형성되고 이들 사이에 격벽(83)이 가로로 연결되어 있으며 상부덮개(84)와 베이스커버(85)가 구비되고 베이스커버(85)에는 등갓(86)과 램프홀더(87)가 설치된다. 그리고 상기 측벽(81)에는 요홈(82)이 형성되어 있다.In the prior art, as shown in FIG. 1, sidewalls 81 are formed on both sides of the duct body 80, and partition walls 83 are horizontally connected between the upper and upper covers 84 and the base cover 85. Is provided and the base cover 85, the lampshade 86 and the lamp holder 87 is installed. A groove 82 is formed in the side wall 81.

또, 상기 격벽(83)의 하부에는 절연튜브(89)가 피복된 전선 지지부재(88)가 전선(91)을 정리하기 위하여 나사못(90)으로 설치되어 있다.In addition, the lower portion of the partition 83, the wire support member 88 is coated with an insulating tube (89) is provided with a screw (90) to organize the wire (91).

상기와 같이 구성되는 종래기술은 전선을 배선하고 동시에 형광등과 같은 조명기구를 편리하게 설치할 수 있는 기술이지만, 다음과 같은 문제점이 있다.The prior art, which is configured as described above, is a technology that can wire wires and at the same time conveniently install lighting equipment such as fluorescent lamps, but has the following problems.

첫째, 측벽(81)의 요홈(82)이 형성된 부분이 구조적으로 취약한 문제점이 있다. First, there is a problem in that the portion where the recess 82 of the side wall 81 is formed is structurally weak.

즉, 측벽(81)의 하단에 결합한 베이스커버(85)는 양쪽의 걸림부(85a)에 의하여 측벽(81)의 걸림부(81a)에 결합하고 있는데, 베이스커버(85)에는 등갓(86), 램프홀더(87), 램프, 안정기 등으로 구성된 형광등이 설치되어 있으므로 이 형광등의 하중이 측벽(81)의 지지력보다 크면 형광등이 설치되어 있는 베이스커버(85)가 측벽(81)으로부터 떨어져 나가는 불상사가 발생할 수 있다. That is, the base cover 85 coupled to the lower end of the side wall 81 is coupled to the locking portion 81a of the side wall 81 by both locking portions 85a, and the lampshade 86 is attached to the base cover 85. Since a fluorescent lamp composed of a lamp holder 87, a lamp, a ballast, and the like is installed, if the load of the fluorescent lamp is greater than the supporting force of the side wall 81, the base cover 85 having the fluorescent lamp is separated from the side wall 81. May occur.

부연컨대, 측벽(81)의 요홈(82)은 이 부분에서 약간 벌어지는 등의 변형이 쉽게 발생하는 취약한 부분이며 이 부분의 변형에 의해 베이스커버(85)를 잡아주고 있는 측벽(81)의 결합력이 약화하여 형광등이 배선 덕트로부터 이탈될 수 있는 것으로 이 부분의 보강이 요구된다.In other words, the groove 82 of the side wall 81 is a fragile portion where deformation such as a slight gap occurs easily in this portion, and the coupling force of the side wall 81 holding the base cover 85 is deformed by the deformation of this portion. Reinforcement of this part is required as it can be weakened and the fluorescent lamp can be separated from the wiring duct.

둘째, 등갓(86)을 베이스커버(85)에 설치하는 구조로 된 것이어서 그 설치작업이 번거로운 문제점이 있다.Second, there is a problem that the installation work is cumbersome because the lampshade 86 is installed in the base cover 85.

즉, 등갓(86)을 베이스커버(85)에 설치하려면 베이스커버(85)를 덕트 본체(80)에 설치하고 다시 베이스커버(85)에 등갓(86)을 설치하기 위한 설치구조를 구성한 다음 이에 등갓(86)을 설치하여야 하므로 작업이 번거로울 뿐만 아니라, 등갓(86)이 설치되는 부분에서는 베이스커버(85)가 등갓(86)과 중복 설치되어 베이스커버(85)가 낭비되는 결점이 있다.That is, in order to install the lampshade 86 on the base cover 85, the base cover 85 is installed on the duct body 80, and then the mounting structure for installing the lampshade 86 on the base cover 85 is configured. Since the lampshade 86 needs to be installed, the work is cumbersome, and in the part where the lampshade 86 is installed, the base cover 85 is overlapped with the lampshade 86 so that the base cover 85 is wasted.

셋째, 전선(91)을 배선하기 위하여 절연튜브(89)가 피복된 전선 지지부재(88)와 이를 고정하는 나사못(90)을 사용하여야 하기 때문에 3가지의 부속품이 추가되고 이에 따른 작업이 늘어나게 되므로 설치비용을 상승시키는 단점이 있다.Third, since three wires are added to the wire support member 88 coated with the insulating tube 89 and the screws 90 fixing the wire 91, three accessories are added and the work accordingly increases. There is a disadvantage of increasing the installation cost.

본 발명은 상기와 같은 종래의 문제점을 해결하고자 덕트 본체의 측벽을 보강하고 등갓은 덕트 본체에 직접 설치가능하게 하며 배선공간을 본체에 확보하여 부품수를 줄일 수 있는 조명등기구가 설치되는 배선 덕트를 제공함에 그 목적이 있다.The present invention reinforces the side wall of the duct body and the lampshade can be installed directly on the duct body in order to solve the conventional problems as described above, the wiring duct is installed to the lighting luminaire which can reduce the number of parts by securing the wiring space in the body The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 발명은 외부 중간에 연결홈이 형성된 양 측벽과, 이 양 측벽의 내측에 연결홈으로 생긴 돌출부를 감싸는 형태로 형성된 보강수단과, 이 보강수단을 가로로 연결하는 격벽과, 이 격벽의 상부에 마련되고 상부로 개구되는 배선공간과, 이 배선공간의 개구부를 덮는 상부커버와, 상기 격벽의 하부에 마련되고 하부로 개구되는 조명기구의 전기장치수납공간과, 이 전기장치수납공간의 개구부에 설치되는 등갓과, 이 등갓이 없는 부분을 덮는 하부커버를 구비하여서 된 특징이 있다.The present invention for achieving the above object is a reinforcing means formed in the form of surrounding the both side wall formed with a connection groove in the middle of the outside, the protrusion formed by the connection groove in the inner side of both side walls, and connecting the reinforcement means horizontally A partition wall, a wiring space provided at an upper portion of the partition wall and opening upward, an upper cover covering an opening of the wiring space, an electrical device storage space of a lighting device provided at a lower portion of the partition wall and opened downward; It is characterized by having a lampshade provided in the opening of the electrical device storage space and a lower cover covering the part without the lampshade.

또 본 발명은 상기 등갓의 상면에 덕트 본체의 전기장치수납공간의 개구부에 결합할 수 있는 결합수단을 형성하여서 된 다른 특징이 있다.In another aspect, the present invention is characterized by forming a coupling means that can be coupled to the opening of the electrical device storage space of the duct body on the upper surface of the lampshade.

또 본 발명은 상기 등 기구의 소켓을 3등형으로 구성하여서 된 다른 특징이 있다.In addition, the present invention has another feature in that the socket of the lamp is configured in a third lamp.

상기와 같은 특징을 지닌 본 발명은 배선 덕트의 측벽을 보강하여 측벽의 변형요인을 제거함으로써 형광등이 배선 덕트 본체로부터 떨어져 나갈 염려가 없어지고 동시에 등 기구를 배선 덕트 본체에 직접 설치가능하게 하여 작업능률을 향상시키며 종래의 베이스커버가 불필요하게 낭비되는 것을 방지함으로써 자재절감효과를 얻은 것 등의 이점이 있다.The present invention having the above characteristics eliminates the possibility of the fluorescent lamp falling off from the wiring duct body by reinforcing the sidewalls of the wiring ducts, and at the same time, it is possible to install the lamp fixture directly on the wiring duct body, thereby improving work efficiency. This is advantageous in that the material saving effect is obtained by preventing the unnecessary waste of the conventional base cover.
