장식용 엘이디 라이트 파이프{A light}Decorative LED Light Pipes {A light}

본 발명은 관체로 이루어진 장식용 LED 라이트 파이프의 조명구조에 관한 것으로 특히 LED를 사용한 조명기구에 적용되어지면서 장식을 위하여 다양한 형태의 관체에 적용이 가능하고, 간단하게 연속으로 연결사용이 가능토록 한 것이다.The present invention relates to a lighting structure of a decorative LED light pipe made of a tube, in particular to be applied to a luminaire using the LED is possible to be applied to various types of tube for decoration, it is possible to simply connect and use continuously. .

현재 장식용의 조명기구에 관한 것으로 특히 LED를 사용하여 시공되어지는 일반적인 관체의 구조는 대략 원형의 형태로 이루어지고 상측의 일부는 개구되어 개구부가 형성되고 상기 개구부에 일정한 각도를 유지하여 빛의 반사가 용이하도록 LED가 장착된 기판이 위치되어지는 것이다.The present invention relates to a decorative lighting fixture, and in particular, the structure of a general tube that is constructed by using an LED has a substantially circular shape, and an upper part thereof is opened to form an opening, and the light is reflected by maintaining an angle at the opening. The substrate on which the LED is mounted is located to facilitate.

따라서 이러한 기판의 장착을 위하여 관체의 상단에 LED가 장착된 기판이 끼워지기 위하여 일정간격을 유지한 상태에서 2줄의 가이드돌기를 형성하게 되는 것이다.Therefore, in order to mount such a substrate, two rows of guide protrusions are formed while maintaining a predetermined interval so that the substrate on which the LED is mounted on the top of the tube is fitted.

또한 상기 가이드돌기에 끼워진 기판의 이탈을 방지하기 위하여 관체의 양측으로 마개를 형성함에 있어서 상기 마개를 관체의 내측으로 가이드돌기로 인하여 내입되어지게 형성할 수 없어 대부분 관체에는 나사홀을 형성토록 한 후 마개를 관체의 외측에 단지 막아주는 형태에서 나사등을 이용하여 관체에 형성된 나사홀에 고정토록 하고 있는 것이다.In addition, in order to form a stopper on both sides of the tube in order to prevent the separation of the substrate fitted to the guide protrusion, the stopper can not be formed to be inserted into the inside of the tube due to the guide protrusion to form a screw hole in most of the tube after The plug is to be fixed to the screw hole formed in the pipe by using a screw or the like in the form of merely blocking the outside of the pipe.

또한 이러한 마개에는 구멍이 형성되어 기판에 전원을 공급하기 위한 전원선이 노출되어져 관체를 연속으로 길게 형성토록 할 경우에는 전선을 사용하여 연결하게 되는 것이다.In addition, the plug is formed in the hole is exposed to the power line for supplying power to the substrate to form a long continuous pipe is to connect using a wire.

따라서 이러한 전선의 노출로 조명에서 많은 문제점은 발생토록 함은 물론 마개의 고정을 위한 별도의 조립수단과 조립구를 사용함으로 원가의 상승은 물론 이러한 연결을 위한 작업상의 곤란함도 존재하였던 것이다.Therefore, there are many problems in lighting due to the exposure of these wires, as well as the rise of cost as well as the difficulty of working for such a connection by using a separate assembly means and assembly for fixing the stopper.

따라서 본 발명에서는 이러한 문제점을 해결함은 물론 간단한 조립구조와 다양한 관체에 적용이 가능토록 함은 물론 연속적인 연결을 위한 구조를 제공하기 위한 것이다.Therefore, the present invention is to solve the above problems, as well as to provide a simple assembly structure and the structure for the continuous connection to be applicable to various pipes.

특히 LED를 사용하여 LED가 관체에 장착할 경우에 LED가 장착된 기판이 관체의 개구되어진 상측에 위치되이야 하고 상기 관체의 양측으로는 마개를 장착하여야 함으로 기판의 고정을 간단하게 하고 마개의 장착을 용이토록 하기 위한 관체의 구조에 관한 것이다.In particular, when the LED is mounted on the tube by using the LED, the board on which the LED is mounted should be located on the upper side of the opening of the tube, and the stopper should be mounted on both sides of the tube to simplify the fixing of the substrate and to install the plug. It relates to the structure of the tube to facilitate the.

이를 위하여 관체와 기판이 별도의 내입체에 의하여 장착토록 하고, 상기 내입체는 관체의 내부에 슬라이드되면서 삽입토록 하여 다양한 관체의 구조에도 적용이 가능토록 하면서 이러한 내입체의 길이를 짧게 사용함으로서 일정한 길이를 갖는 마개를 사용토록 함으로서 이러한 마개를 소켓으로 구현함으로서 전선이 없이 간단한 연결젝에 의하여 연속으로 연결이 가능토록 한 것이다.To this end, the tube and the substrate are mounted by a separate intergranular body, and the intergranular body is inserted into the inside of the tube while being inserted into the tube. By using a stopper having such that by implementing the plug as a socket it is possible to connect continuously by a simple connection without wires.

따라서 간단하게 조립이 가능하고 기판의 크기가 작아도 됨은 물론 다양한 관체에 적용이 가능하게 되고, 소켓의 구조로 마개를 사용토록 할 수 있게 됨으로서 연속으로 간단한 연결이 가능하게 되는 것이다.Therefore, it is possible to simply assemble and the size of the substrate is small, as well as to be applied to a variety of pipes, it is possible to use a stopper in the structure of the socket to enable a simple connection in series.

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도1에 도시된 바와 같이 본 발명의 구조는 일정한 내공간(11)을 갖는 관체(10)와 상기 관체(10)의 상측으로는 일정 폭으로 개구되어진 개구부(12)가 형성되고 상기 개구부의 직하방으로는 가이드홈(13)이 형성되며 그 상측으로는 걸림돌기(15)가 형성되고 개구되어진 개구부의 선단으로는 끼임홈테(16)가 형성되어지는 것이다.As shown in FIG. 1, the structure of the present invention includes a tubular body 10 having a constant inner space 11 and an opening 12 formed at a predetermined width on the upper side of the tubular body 10, and directly below the opening. A guide groove 13 is formed in the room, and a locking protrusion 15 is formed on the upper side thereof, and a clamping groove 16 is formed at the tip of the opening.

또한 상기 가이드홈(13)에 끼워지기 위한 수직판(21)과 상기 수직판(21)과 직교하게 형성되는 수평판(22)으로 이루어지는 내입체(20)는 수평판(22)에는 2줄의 돌출테(23)를 형성하여 그 사이에 LED(31)가 장착된 기판(30)이 일직선 상으로 장착토록 하는 것이다.In addition, the inner body 20 including the vertical plate 21 to be fitted into the guide groove 13 and the horizontal plate 22 formed perpendicular to the vertical plate 21 has two lines on the horizontal plate 22. Protruding frame 23 is formed so that the substrate 30 on which the LED 31 is mounted is mounted in a straight line.

이때 관체의 가이드홈을 형성하기 위하여 관체의 살두께가 얇게 형성됨으로 보강살(14)을 형성토록 한 후 가이드홈(13)을 형성하는 것이다.At this time, in order to form the guide grooves of the tubular body, the thickness of the tubular body is formed to be thin so as to form the reinforcement meat 14 and then to form the guide grooves 13.

또한 상기 걸림돌기는 양측으로 형성토록 하여 내입체가 가이드홈에 끼워져 삽입될 경우에 삽입된 이후에 상측으로 이탈되어지는 것을 방지하기 위한 것이다.In addition, the locking projection is formed to be on both sides to prevent the inner body is separated from the upper side after being inserted when inserted into the guide groove.

또한 상기 개구부의 선단에 형성된 끼임홈테에는 투명커버(도시안됨)를 삽입토록 함으로서 관체 자체만으로 조명수단을 형성토록 할 수 있는 것이다.In addition, by inserting a transparent cover (not shown) in the clamping groove formed at the tip of the opening to be able to form the lighting means only by the tube itself.

또한 상기 관체(10)의 길이보다 내입체(20)의 길이를 짧게 내입토록 한 후 관체의 양측으로는 일정길이로 돌출된 결합돌부(41)를 형성하고 상기 결합돌부(41)의 선단으로는 단자(42)를 형성토록 한 후 상기 결합돌부(41)의 내부에는 숫(43)이 형성된 소켓(40)을 삽입토록 함으로서 내입체(20)가 관체(10)에 삽입된 상태에서 좌우로 이탈되는 것을 방지하게 되는 것이다.In addition, after the length of the inner body 20 is shorter than the length of the tube body 10 to form a coupling protrusion 41 protruding to a predetermined length on both sides of the tube body and as the tip of the coupling protrusion 41 After the terminal 42 is formed, the coupling protrusion 41 is inserted into the socket 40 having the male 43 formed therein, so that the internal body 20 is separated from the left and right in the inserted state in the tubular body 10. It will prevent you from doing so.

따라서 관체의 길이와 내입체의 길이를 달리함으로서 일정한 결합돌부가 형성된 소켓을 사용토록 함으로서 소켓에 숫을 형성토록 하고, 상기 숫에 결합되도록 암(51)이 형성된 연결젝(50)을 사용하여 연결젝에 연속으로 관체를 연결토록 함으로서 간단하게 전선의 노출사용이 없이 간단하여 연속연결이 가능하게 되는 것이다.Therefore, by varying the length of the tube and the length of the inner body to use a socket formed with a constant coupling protrusion to form a male number in the socket, it is connected using a connecting jet 50 formed with an arm 51 to be coupled to the male By connecting the pipes continuously to the projector, it is possible to connect them simply and without using wires.

따라서 관체에 관체보다 짧은 내입체를 내입토록 한 후 관체의 양단으로 소켓을 삽입결합토록 하고, 상기 소켓에는 연결젝을 사용하여 연속으로 연결토록 하는 것이다.Therefore, after inserting a shorter body than the tube into the tube, the socket is inserted into both ends of the tube, and the socket is connected to the socket continuously.
