아울러, 상기 중앙통로(44)와 결합홈(32)은 상호 밀폐링(32-1)에 의해 밀폐됨은 물론이다.In addition, the central passage 44 and the coupling groove 32 is of course sealed by the mutual sealing ring (32-1).
그리고, 방열수단(30)의 상부에 고정된 방열 봉(40)의 외주면(42) 각각에 엘이디 기판(50)이 접착되어 고정된다.Then, the LED substrate 50 is adhered to and fixed to each of the outer circumferential surfaces 42 of the heat dissipation rod 40 fixed to the upper portion of the heat dissipation means 30.
물론, 방열 봉(40) 외주면(42)에 엘이디 기판(50)이 접착고정된 후 방열 봉(40)이 방열수단(30) 상부에 결합 될 수도 있다.Of course, after the LED substrate 50 is fixed to the outer circumferential surface 42 of the heat dissipation rod 40, the heat dissipation rod 40 may be coupled to the top of the heat dissipation means 30.
아울러, 각각의 엘이디 기판(50) 하부에 구비되는 결합돌기(52)와 하부 홈(54)의 결합에 의해 엘이디 기판(50)이 방열 봉(40)의 접착 없이도 상호 결합으로 인해 다각을 이루어 상기 방열 봉(40)의 외주면(42)에 위치되며, 상부에 결합되는 고정기판(60)에 의해 고정될 수도 있다.
In addition, by the coupling of the coupling protrusions 52 and the lower grooves 54 provided in each of the LED substrate 50, the LED substrate 50 is made into a multi-angle due to mutual coupling even without bonding of the heat dissipation rod 40 Located on the outer circumferential surface 42 of the heat dissipation rod 40, it may be fixed by a fixed substrate 60 coupled to the top.
그리고, 상기 방열 봉(40)에 상부에 고정기판(60)이 안착 된다.In addition, the fixing substrate 60 is seated on the heat dissipation rod 40.
이때, 상기 고정기판(60)의 결합홈(62)과 엘이디 기판(50)의 고정돌기(52)가 상호 결합됨은 물론이며, 고정수단에 의해 방열봉(40) 상부에 고정기판(60)이 고정된다.At this time, the coupling groove 62 of the fixing substrate 60 and the fixing protrusion 52 of the LED substrate 50 are coupled to each other, and the fixing substrate 60 is formed on the heat dissipation rod 40 by the fixing means. It is fixed.
그리고, 상기와 같이 소켓결합수단(20), 방열수단(30), 방열 봉(40), 엘이디 기판(50), 고정기판(60)이 상호 결합된 상태에서 커버(70)의 하부가 방열수단(30)의 상부와 상호 나사 결합에 의해 결합 된다.In addition, the socket coupling means 20, the heat dissipation means 30, the heat dissipation rod 40, the LED substrate 50, the fixed substrate 60 in the state in which the lower portion of the cover 70 is heat dissipation means as described above. The upper part of 30 is coupled by mutual screwing.
이때, 상기 순환공(72)은 방열 봉(40)의 중앙통로(44) 상부와 상호 결합되고, 물론 밀폐링(74)에 의해 밀폐된다.
At this time, the circulation hole 72 is mutually coupled with the upper portion of the central passage 44 of the heat dissipation rod 40, and is sealed by the sealing ring 74, of course.
상기와 같이 상호 결합된 엘이디 조명등은 도 4에 도시된 바와 같이 소켓연결수단(20)에 의해 외부전원이 유입되면 제어부재(26)에 의해 엘이디 기판(50)의 엘이디가 조명을 조사한다.As described above, the LED lamps coupled to each other as illustrated in FIG. 4, when external power is introduced by the socket connecting means 20, the LEDs of the LED substrate 50 are illuminated by the control member 26.
그리고, 도 5에 도시된 바와 같이 엘이디에서 발생하는 열기는 방열 봉(40)의 외주면(42) 및 방열날개(43)를 통해 방열공간(48)으로 방열되고, 방열공간(48)의 열기는 중앙통로(44) 방열 된다.
이때, 외부공기가 커버(70)의 순환공(72)을 통해 중앙통로(44)로 유입되어 중앙통로(44)에서 상호 열 교환을 이루어 중앙통로(44)를 통해 방열수단(30)의 방열 홀(32)을 거쳐 방열통로(34)로 배출되게 된다.And, as shown in Figure 5 the heat generated from the LED is radiated to the heat dissipation space 48 through the outer peripheral surface 42 and the heat dissipation wing 43 of the heat dissipation rod 40, the heat of the heat dissipation space 48 The central passage 44 is radiated.
At this time, the outside air flows into the central passage 44 through the circulation hole 72 of the cover 70 to perform mutual heat exchange in the central passage 44 to dissipate the heat dissipation means 30 through the central passage 44. It is discharged to the heat dissipation passage 34 through the hole (32).
그리고, 상기 순환공(72), 중앙통로(44), 방열홀(32)이 상호 밀폐링(32-1,74)에 의해 밀폐되어 방수 및 방진됨으로 외부의 습기 및 먼지에 의해 발생하는 누전 또는 고장을 방지할 수 있는 것이다.In addition, the circulation hole 72, the central passage 44, and the heat dissipation hole 32 are sealed by the mutual sealing rings 32-1 and 74 to be waterproof and dustproof, thereby causing leakage or leakage caused by external moisture and dust. It can prevent malfunction.
더욱 바람직하게는, 방열 봉(40)의 방열공간(48)과 방열수단(30)의 공간부(36)가 상호 연통 되어 다시 한번 열 교환을 이루어 방열장공(38)을 통해 엘이디의 열기가 더욱 용이하게 외부로 배출된다.
그러므로, 엘이디의 방열열기는 순환공(72), 중앙통로(44), 방열 홀(32), 방열통로(34)가 연통되어 외부공기의 자유로운 순환 및 열교환에 의해 용이하게 방열 되며, 상호 밀폐됨으로 인해 엘이디 기판(50)이 외부의 습기 및 먼지에 의해 발생할 수 있는 누전 또는 고장을 방지할 수 있다.More preferably, the heat dissipation space 48 of the heat dissipation rod 40 and the space portion 36 of the heat dissipation means 30 communicate with each other once again to exchange heat to heat the LED through the heat dissipation hole 38. It is easily discharged to the outside.
Therefore, the heat dissipation heater of the LED communicates with the circulation hole 72, the central passage 44, the heat dissipation hole 32, and the heat dissipation passage 34 to easily dissipate heat due to free circulation and heat exchange of external air, and is sealed to each other. Due to this, the LED substrate 50 may prevent a short circuit or failure that may be caused by external moisture and dust.
또한, 엘이디를 제어하기 위한 제어부재(26)가 별도로 분리 및 밀폐되어 방수 및 방진됨으로 외부의 습기 및 먼지에 의해 발생할 수 있는 누전 및 고장을 방지할 수 있다.
In addition, since the control member 26 for controlling the LED is separately separated and sealed to be waterproof and dustproof, a short circuit and a failure that may be caused by external moisture and dust may be prevented.
