..

[발명이 속하는 기술 분야 및 그 분야의 종래기술][TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

본 발명은 램프추락방지용 홀더가 구비된 엘이디 터널 등기구에 관한 것이다.The present invention relates to an LED tunnel luminaire provided with a holder for preventing a fall of a lamp.

터널용 등기구는 도 7과 같이 터널 천장에 고정되는데 상부 몸체(4)의 외측 상면에 고정대가 조립되어 있어서 등기구 전체를 터널 천장에 고정시키는 것이 가능한 바, 상술한 고정대는 앵커볼트를 통해 터널 천장에 고정된다.As shown in FIG. 7, the luminaire for a tunnel is fixed to a tunnel ceiling. The luminaire can be fixed to a tunnel ceiling by fixing a fixing base on an outer upper surface of the upper body 4. The fixing base is fixed to a tunnel ceiling through an anchor bolt .

그리고 엘이디 램프(50)는 전원 소켓(3)에 끼워져 조립이 되는데 보통의 막대형 형광등과 거의 동일한 외형을 가지고 있으며 전원 소켓(3)의 상면에 형성된 절개구멍 안으로 전극을 삽입한 후 직각으로 회전을 시키면 엘이디 램프(50)는 전원 소켓(3)에 조립이 되고 스위치를 켜면 점등이 되는 바, 보통의 막대형 형광등을 전원 소켓에 조립하는 요령과 동일하다.The LED lamp 50 is assembled by being fitted into the power socket 3. The LED lamp 50 has almost the same shape as an ordinary rod-shaped fluorescent lamp. The LED lamp 50 is rotated at a right angle after inserting the electrode into the incision hole formed on the upper surface of the power socket 3 The LED lamp 50 is assembled to the power socket 3 and turned on when the switch is turned on, and the same procedure as assembling a normal rod-shaped fluorescent lamp into the power socket is performed.

그런데, 터널은 거의 24시간 동안 차량이 통과하기 때문에 차량의 엔진음과 배기음, 차량의 진행으로 인한 풍절음 때문에 발생되는 진동이 항상 터널 천장에 고정된 등기구에 작용하게 되고 미세한 지진파도 영향을 끼치지 않는다고 할 수 없기 때문에 전원 소켓(3)에 조립된 엘이디 램프(50)가 시간이 경과할수록 전원 소켓(3)으로부터 점점 회전하여 결국 추락하게 되는 현상이 다소 빈번하게 발생되고 있다.However, since the tunnel passes through the vehicle for almost 24 hours, the vibration caused by the engine sound and the exhaust sound of the vehicle and the wind noise due to the progress of the vehicle always acts on the luminaire fixed to the tunnel ceiling and does not affect the fine seismic waves The LED lamp 50 assembled in the power socket 3 gradually rotates from the power socket 3 as time elapses and eventually falls down.

따라서 터널 내부가 순간적으로 어두워지게 됨에 따라 차량의 안전주행을 방해하는 원인이 되고 나아가 가장 바깥쪽의 차로를 막고 엘이디 램프 교체 또는 재조립을 위한 작업이 이루어져야 하기 때문에 차량의 소통을 방해하는 불편함을 초래하게 되며 불필요한 작업인력이 투입되어야 함으로써 지방자치단체의 재정 관리 및 지출에 좋지 않은 영향을 초래하게 된다.As a result, the inside of the tunnel is instantly darkened, which interferes with the safe driving of the vehicle. Furthermore, since it is necessary to prevent the outermost lane and to replace or reassemble the LED lamp, the inconvenience And the unnecessary workforce must be input, which will adversely affect the financial management and expenditure of local governments.

이에 종래의 등기구에 대한 특허선행기술문헌을 살피기로 한다.Therefore, the patent prior art literature for a conventional luminaire will be examined.

먼저 특허등록 제10-1249386호는 직류 및 교류 전원을 공급토록 컨버터가 구비된 등기구로써 엘이디 램프를 전원 소켓에 조립하는 구조가 매우 복잡하여 고장의 발생 가능성이 높고 제작단가도 크게 상승되는 문제가 있으며 본 발명의 램프추락방지용 홀더와 같은 수단이 없다.First, Patent Registration No. 10-1249386 has a problem in that the structure for assembling the LED lamp into the power socket as a luminaire equipped with a converter for supplying direct current and alternating current power is very complicated, and there is a high possibility of occurrence of a failure, There is no means such as the holder for preventing fall of the lamp of the present invention.

다음, 실용신안등록 제20-0465183호는 형광등을 조립하는 전원 소켓의 구조가 본 발명과 상이하며 본 발명의 램프추락방지용 홀더와 같은 수단이 없다.Next, in the Utility Model Registration No. 20-0465183, the structure of the power socket for assembling the fluorescent lamp is different from that of the present invention, and there is no means such as a holder for preventing fall of the lamp of the present invention.

다음, 실용신안등록 제20-실0123505호는 보통의 형광등기구에 관한 것으로 본 발명의 램프추락방지용 홀더와 같은 수단이 없다.Next, the Utility Model Registration No. 20-Room 0123505 relates to an ordinary fluorescent lamp apparatus, and there is no such means as the lamp fall prevention holder of the present invention.

다음, 실용신안등록 제20-0208065호는 형광등 홀더를 고정하는 장치인데 본 발명과 같이 램프추락방지용 홀더에 그리퍼(16)가 일체로 구비되는 구조가 아니고 보통의 형광등 홀더를 조립하는 고정체에 관한 것으로 본 발명과는 상이하다.Next, the utility model registration No. 20-0208065 fixes the fluorescent lamp holder. However, the present invention is not a structure in which the gripper 16 is integrally provided in the holder for preventing fall of the lamp as in the present invention, Which is different from the present invention.

[발명이 이루고자 하는 기술적 과제][Technical Problem]

본 발명은 지속적인 진동이나 간헐적인 충격이 가해져도 등기구에 구비된 전원 소켓에 엘이디 램프가 가장 안정적으로 조립된 상태를 유지하여 기능을 발휘하도록 함은 물론 엘이디 램프가 전원 소켓으로부터 이탈하여 추락하는 문제를 해결할 수 있는 등기구를 제안하는 것이 과제이다.The present invention can maintain the state in which the LED lamp is most stably assembled in the power socket provided in the luminaire, thereby enabling the LED lamp to fall out of the power socket and fall down It is a challenge to propose a luminaire that can be solved.

[발명의 구성 및 작용][Structure and operation of the invention]

본 발명은 아래와 같은 구조로 이루어진다.The present invention has the following structure.

투명 창(5)이 고정된 하부 몸체(4)와;A lower body 4 to which the transparent window 5 is fixed;

하부 몸체(4)와 힌지(6)로 연결되는 상부 몸체(1)와;An upper body 1 connected to the lower body 4 and the hinge 6;

상부 몸체(1)의 안쪽 바닥에 볼트 및 너트 또는 스폿용접으로 고정되는 지지대(2)와;A support base (2) fixed to the inner bottom of the upper body (1) by bolts and nuts or spot welding;

지지대(2)에 고정되는 전원 소켓(3)과;A power socket (3) fixed to the support base (2);

지지대(2)에 나사로 고정되는 반사 판(7)과;A reflection plate (7) screwed to the support base (2);

마주보는 전원 소켓(3) 사이의 위치에서 지지대(2)에 고정나사(60)로 고정되는 램프추락방지용 홀더로 구성되며,And a lamp fall preventive holder which is fixed by a fixing screw (60) to the support (2) at a position between opposing power sockets (3)

램프추락방지용 홀더는,In the holder for preventing the fall of the lamp,

반사 판(7)을 관통하여 지지대(2)에 조립되는 고정 나사(60)가 관통하는 구멍(12)이 형성된 돌출단(11), 돌출단(11)과 직각을 이룬 채 한 몸으로 된 수직단(13), 수직단(13)의 위쪽에 한 몸으로 구비되며 형광등 타입의 엘이디 램프(50)를 끼워서 물릴 수 있도록 하는 그리퍼(16), 수직단(13)이 1mm 미만의 범위 안에서 휘어질 수 있도록 하기 위해 수직단(13)의 측면과 안쪽 면에 형성된 절개부(14) 및 홈(15)으로 구성된 것을 특징으로 한다.A protruding end 11 formed with a hole 12 through which a fixing screw 60 passing through the reflecting plate 7 passes and which is assembled to the supporting base 2, A gripper 16 provided on the upper end of the stage 13 and the vertical end 13 so as to be able to hold the LED lamp 50 of the fluorescent lamp type and the vertical end 13 bent in a range of less than 1 mm And a cutout portion 14 and a groove 15 formed on the side surface and the inner surface of the vertical end 13 in order to allow the first and second end portions 13,

이렇게 구성되는 본 발명은 도 1과 같이 지지대(2) 위에 고정되는 전원 소켓(3)의 마주보는 사이에 램프추락방지용 홀더(A)가 조립이 되는데, 지지대(2) 위에는 도 5와 같이 반사 판(7)이 위치하게 되며 반사 판(7)의 오목한 부분 중앙에는 도 6과 같이 램프추락방지용 홀더(A)의 돌출단(11)이 얹히도록 한다.1, the holder A for preventing the fall of the lamp is assembled between the opposing sides of the power socket 3 fixed on the support 2. On the support 2, The protruding end 11 of the holder A for preventing the fall of the lamp is placed on the center of the concave portion of the reflection plate 7 as shown in FIG.

이어서 고정나사(60)를 돌출단(11)의 구멍(12) 안으로 삽입하여 지지대(2)에 조립되도록 하면 램프추락방지용 홀더(A)는 지지대(2) 위에 견고하게 고정이 되는데, 반사 판(7)에는 고정 나사(60)가 관통하는 구멍을 형성시켜 두는 것이 바람직할 것이다.When the fixing screw 60 is inserted into the hole 12 of the projecting end 11 and assembled to the support base 2, the holder A for preventing the fall of the lamp is firmly fixed on the support base 2, 7, it is preferable to form a hole through which the fixing screw 60 passes.

다음, 도 1과 같이 된 본 발명의 상태에서 전원 소켓(3)에 엘이디 램프(50)를 끼워서 조립을 시키게 되는데, 전원 소켓(3)에 엘이디 램프(50)를 끼울 때 램프추락방지용 홀더(A)의 그리퍼(16) 사이로 엘이디 램프(50)를 끼움과 동시에 엘이디 램프(50)의 전극을 전원 소켓(3)에 삽입하여 직각으로 회전을 시키게 된다.1, when the LED lamp 50 is inserted into the power socket 3, the lamp fall preventing holder A (see FIG. 1) The LED lamp 50 is inserted into the power socket 3 at the same time that the LED lamp 50 is rotated at right angles.

이때 수직단(13)은 그리퍼(16)와 함께 도 4를 기준하여 좌측으로 약간(1mm 미만) 기울어지게 되는데 이에 따라 엘이디 램프(50)를 전원 소켓(3)에 조립을 완료하면 수직단(13)은 다시 수직으로 복원하려는 탄성이 작용하기 때문에 그리퍼(16)에 끼워진 엘이디 램프(50)의 전극이 전원 소켓(3) 내부의 전극판을 강하게 밀면서 조립된 상태를 유지하게 된다.At this time, the vertical end 13 is slightly inclined to the left side (less than 1 mm) with reference to FIG. 4 together with the gripper 16. When the LED lamp 50 is assembled to the power socket 3, The electrode of the LED lamp 50 inserted into the gripper 16 strongly presses the electrode plate inside the power socket 3 and maintains the assembled state.

그러므로 진동이나 충격이 가해져도 본 발명의 램프추락방지용 홀더(A)가 위와 같이 엘이디 램프(50)의 전극이 전원 소켓(3)에 강한 힘을 가하면서 조립이 되어 있도록 하는 안정된 상태를 이끌어 낼 수가 있기 때문에 엘이디 램프(50)가 회전하지 않게 되고 나아가 전원 소켓(3)으로부터 이탈하여 추락하는 경우가 없어지는 것이다.Therefore, even if vibrations or shocks are applied, the lamp falling preventive holder A of the present invention can lead to a stable state in which the electrode of the LED lamp 50 is assembled while applying a strong force to the power socket 3 So that the LED lamp 50 does not rotate, and furthermore, it does not fall off from the power socket 3 and fall down.

한편, 본 발명의 램프추락방지용 홀더(A)의 재질은 탄성이 우수하면서 질긴 성질을 가지는 플라스틱 또는 합성수지로 제작하는 것이 바람직하며 수직단(13)의 절개부(14)는 도 3을 기준하여 상하로 2개소에 형성시킬 수도 있고 하나의 절개부(14)의 틈새를 상하로 더 크게 형성시키는 등의 응용 실시를 할 수 있음은 당연한 이치이다.It is preferable that the material of the holder A for preventing falling of the lamp according to the present invention is made of plastics or synthetic resin having excellent elasticity and toughness and the incised portion 14 of the vertical end 13 is made up and down It is obviously possible to carry out the application such as forming two cut-out portions 14 with a larger gap up and down.

이러한 본 발명은 지속적인 진동이나 간헐적인 충격이 가해져도 등기구에 구비된 전원 소켓에 엘이디 램프가 가장 안정적으로 조립된 상태를 유지하여 기능을 발휘하도록 함은 물론 엘이디 램프가 전원 소켓으로부터 이탈하여 추락하는 문제를 해결할 수 있는 효과가 있다.In the present invention, even when continuous vibration or intermittent impact is applied, the LED lamp is most stably assembled to the power socket provided in the luminaire so as to exhibit its function, and the LED lamp is detached from the power socket Can be solved.
