지지프레임(320)은 진동소자(310)보다 두껍게 형성되어 커버(200)의 상부수용부(220)에 삽입되어서 고정된다. 이때 진동소자(310)의 전방 및 후방에 여유 공간이 형성된다. 즉 지지프레임(320)들에 양단이 고정되는 진동소자(310)는 중간부분이 자유롭다. The support frame 320 is formed to be thicker than the vibrating element 310 and is inserted into and fixed to the upper accommodating portion 220 of the cover 200 . At this time, extra spaces are formed in front and rear of the vibration element 310 . That is, the middle portion of the vibration element 310, both ends of which are fixed to the support frames 320, is free.

진동블록(330)은 진동소자(310)에서 발생되는 진동을 커버(200)로 전달한다. The vibration block 330 transfers vibration generated from the vibration element 310 to the cover 200 .

따라서 입력되는 전기에너지에 의해 진동소자(310)가 진동되어서 전후방으로 휘어진다. 이때 진동소자(310)와 함께 진동블록(330)이 유동되어서 진동한다. 이에 의해 커버(200)의 투명창(230)에 쌓이는 흙이나 먼지와 같은 이물질이 유동되어서 투명창(230)에 부착되지 않게 된다. Therefore, the vibrating element 310 is vibrated by the input electric energy and is bent forward and backward. At this time, the vibration block 330 is moved together with the vibration element 310 to vibrate. As a result, foreign substances such as soil or dust accumulated on the transparent window 230 of the cover 200 flow and are not attached to the transparent window 230 .

또한 본 발명은 커버(200)에 구비된 상태로 신호램프(100)에서 발생되는 열기를 커버(200)의 외부로 방열하는 방열부재(400)를 포함한다. In addition, the present invention includes a heat dissipation member 400 that dissipates heat generated from the signal lamp 100 to the outside of the cover 200 while being provided in the cover 200 .

방열부재(400)는 신호램프(100)의 열기를 흡열하는 냉각면 및 냉각면에 반대되면서 흡열된 열기를 방열하는 방열면이 형성되는 열전소자(410)와, 열전소자(410)가 장착된 상태로 커버(200)의 내측수용부(240)에 수용되는 열전달판(420)을 포함한다. The heat dissipation member 400 includes a thermoelectric element 410 having a cooling surface for absorbing heat from the signal lamp 100 and a heat dissipation surface for dissipating the absorbed heat as opposed to the cooling surface, and the thermoelectric element 410 is mounted thereon. It includes a heat transfer plate 420 accommodated in the inner accommodating portion 240 of the cover 200 in a state.

열전소자(410)는 전원이 입력되면 냉각면에서 냉기가 방열되고 방열면에서 열기가 방열된다. 이때 열전소자(410)의 냉각면이 신호램프(100)에 접촉되므로 열기를 발산하는 신호램프(100)이 냉각된다. 그리고 냉각면으로 흡수되는 열기가 방열면을 통해 방열되고, 방열되는 열기가 열전달판(420)으로 전달되고 커버(200)로 전달된 후에 커버(200)의 외측으로 배출된다. 즉 신호램프(100)에서 발생되는 열기가 커버(200)의 외부로 배출된다. When power is applied to the thermoelectric element 410, cold air is radiated from the cooling surface and hot air is radiated from the heat dissipating surface. At this time, since the cooling surface of the thermoelectric element 410 contacts the signal lamp 100, the signal lamp 100 that emits heat is cooled. Further, the heat absorbed by the cooling surface is dissipated through the heat dissipating surface, and the dissipated heat is transferred to the heat transfer plate 420 and transferred to the cover 200 and then discharged to the outside of the cover 200 . That is, heat generated from the signal lamp 100 is discharged to the outside of the cover 200 .

열전달판(420)은 열전달효율이 높은 금속으로 구성되어 열전소자(410)가 삽입되어서 장착되는 장착홈(421)이 형성된다. 이러한 열전달판(420)이 내측수용부(240)에 삽입되어서 커버(200)에 밀착되면 열전소자(410)가 신호램프(100)에 밀착된다. The heat transfer plate 420 is made of a metal having high heat transfer efficiency and has a mounting groove 421 into which the thermoelectric element 410 is inserted and mounted. When the heat transfer plate 420 is inserted into the inner accommodating portion 240 and adheres to the cover 200, the thermoelectric element 410 adheres to the signal lamp 100.

따라서 신호램프(100)에서 발생되는 열기가 열전소자(410) 및 열전달판(420)을 통해 커버(200)의 외부로 배출된다. 즉 신호램프(100)에서 발생되는 열기가 커버(200)의 외부로 배출되므로 열기에 의한 신호램프(100)의 고장을 미연에 방지할 수 있다. Accordingly, heat generated from the signal lamp 100 is discharged to the outside of the cover 200 through the thermoelectric element 410 and the heat transfer plate 420 . That is, since heat generated from the signal lamp 100 is discharged to the outside of the cover 200, failure of the signal lamp 100 due to heat can be prevented in advance.

이와 같이, 본 발명에 의하면 횡단보도의 바닥에 구비되어 보행신호인 녹색 빛을 발산하고 정지신호인 적색 빛을 발산하는 신호등의 상부에 쌓이는 이물질이 부착되지 않게 하면서 저감되게 하여 신호등의 시인성을 확보할 수 있으므로 매우 유용한 발명이라 할 수 있다. In this way, according to the present invention, the visibility of the traffic light is secured by reducing foreign substances accumulated on the top of the traffic light provided on the floor of the crosswalk to emit green light as a walking signal and red light as a stop signal without being attached. It can be said that it is a very useful invention.
