Description

엘이디 방폭등{EXPLOSION FREE LAMP WITH LED}LED Explosion-proof Lamp {EXPLOSION FREE LAMP WITH LED}

본 발명은 엘이디램프를 채택함으로써 케이싱이 경량 소형화되어 제조비용이 절감되고 취급 관리가 간편함과 아울러 엘이디램프와 전원구동부의 케이싱이 분리형성되고 연결기둥을 매개로 이격 배치되는 한편 자연대류 촉진 및 열기정체를 방지하는 공기통로가 형성됨으로써 엘이디램프 고열발생에 대한 충분한 방열성능이 뒷받침되어 수명 및 조도가 극대화되는 엘이디 방폭등에 관한 것이다.The present invention adopts the LED lamp, the casing is light and compact, the manufacturing cost is reduced, and the handling and management is easy, and the casing of the LED lamp and the power drive is formed separately and arranged separately from each other through the connecting column while promoting natural convection and thermal stagnation. By forming an air passage to prevent the LED lamp is sufficient heat dissipation performance for high heat generation is related to the LED explosion-proof and the like to maximize the life and illuminance.

일반적으로 가연성 가스가 존재하는 위험 분위기에서 전기기기를 사용할 경우 전기 스파크에 의한 폭발위험성이 존재하기 때문에 점화원을 격리시키거나 고립시키는 것이 필요하지만 현실적으로 점화원의 고립이 불가능하므로 폭발을 방지하기 위한 일반적인 방법으로 내압 방폭 전기기기를 사용하고 있다.In general, when using electrical equipment in a dangerous atmosphere where flammable gases are present, it is necessary to isolate or isolate the ignition source because there is a risk of explosion due to electrical sparks. Pressure-resistant explosion-proof electric equipment is used.

이러한 방폭 전기기기 중 하나로서 산업조명기기인 방폭등의 종래기술(100)은 도 6에 도시된 바와 같이, 고압 수은등, 고압 나트륨등, 메탈할라이드 램프 등과 같이 유리구(球)를 구비하는 램프(110)를 구비하여 되고, 과열 등에 의한 스파 크 발생시 램프의 폭발이 2차 폭발로 이어지는 것을 방지하는 내압 케이싱(130)이 구비된다.As one of such explosion-proof electric devices, the prior art 100 of explosion-proof lamps, which are industrial lighting devices, includes a lamp having a glass ball such as a high pressure mercury lamp, a high pressure sodium lamp, a metal halide lamp, and the like ( 110 is provided, and the pressure-resistant casing 130 is provided to prevent the explosion of the lamp leading to the secondary explosion when a spark occurs due to overheating.

상기 내압 케이싱(130)은 용기 내부에서 램프의 전기 스파크 등으로 폭발성 가스 또는 증기가 폭발했을 때 용기가 그 압력에 견디는 내압력을 가지며, 접합면, 개구부 등을 통해 외부의 폭발성 가스에 인화될 우려가 없는 기밀이 요구된다.The pressure-resistant casing 130 has a pressure resistance to withstand the pressure when the explosive gas or vapor is exploded by the electric spark of the lamp, etc. in the interior of the container, and may be flammable to the external explosive gas through the joint surface, the opening, etc. Confidentiality is required.

따라서, 방폭등의 케이싱은 금속재로 되는 케이싱 본체(131)에 유리 글로브(132)가 긴밀하게 결착되는 구조로 되고 유리 글로브(132) 외부에는 보호망(133)이 형성되는 견고한 구조로 된다.Therefore, the casing such as explosion-proof has a structure in which the glass glove 132 is tightly bound to the casing main body 131 made of a metal material, and a protective net 133 is formed outside the glass glove 132.

또한, 램프(110)가 유리구를 구비하는 형태로 이루어짐으로써 유리 글로브(132)가 유리구를 수용할 수 있는 충분한 내부공간을 확보해야 되고, 유리구 폭발시의 파괴력에 대한 내압력을 가져야 되므로 글로브를 포함하는 케이싱 전체의 두께가 두껍고 크기가 큰 육중한 형태의 방폭구조로 구성된다.In addition, since the lamp 110 is formed in the form of a glass sphere, the glass globe 132 should have a sufficient internal space to accommodate the glass sphere, and must have a pressure resistance against the destructive force during the glass sphere explosion. The entire casing including the glove is composed of a heavy explosion-proof structure having a large thickness and a large size.

이와 같은 종래기술은 램프가 열발광 특성에 의하여 빛을 발하므로 열로 인한 스파크 발생이 빈번하게 발생되어 램프 교체가 빈번하고, 램프교체시에는 상기 육중한 구조의 케이싱을 개폐해야 되므로 램프교체 작업 및 취급이 대단히 어려운 문제점이 있었다.In the prior art, since the lamp emits light due to its heat emission characteristics, sparks are frequently generated due to heat, and thus lamp replacement is frequent, and when the lamp is replaced, it is necessary to open and close the casing of the heavy structure. There was this terribly difficult issue.

한편, 엘이디의 경우에는 열발광이 아닌 반도체의 p-n 접합구조를 이용하여 주입된 소수캐리어(전자 또는 양공)를 만들어내고, 이들의 재결합(再結合)에 의하여 발광이 이루어짐으로써 열에 의한 램프의 스파크 발생위험이 거의 없고, 따라서 엘이디램프를 이용하여 방폭등을 구성한다면 강한 내압구조가 불필요하여 소형화 및 경량화를 가능하게 할 수 있을 것이다.On the other hand, in the case of LED, a small number of carriers (electrons or holes) are injected by using a pn junction structure of a semiconductor rather than heat emission, and light is emitted by recombination thereof, thereby generating sparks of a lamp due to heat. There is almost no risk, and thus, if an explosion proof lamp is constructed using an LED lamp, a strong breakdown voltage structure is unnecessary, and thus it may be possible to reduce the size and weight.

따라서 종래에도 도 7에 도시된 바와 같이, 엘이디램프를 이용하는 방폭등 기술(201)(202)(203)이 개시되어 있으나 엘이디램프와 전원구동부가 일체형 케이싱 내에 설치되는 등으로 방열성능이 뒷받침되지 못하여 조도가 급격히 저하되고 수명이 단축되는 문제점이 있었다.Therefore, as shown in Fig. 7, the explosion-proof lamp technology 201 (202) 203 using the LED lamp is disclosed, but the heat dissipation performance is not supported by the LED lamp and the power driver installed in the integrated casing. There was a problem that the roughness is sharply lowered and the life is shortened.

The casing 30 and the second casing 50 are configured to be spaced apart from each other via the connection column P.

이와 같이, 엘이디램프 방열을 위한 제1케이싱(30)과 전원구동부용 제2케이싱(50)이 분리 이격 배치되고 그 사이에 연결기둥(P) 및 요입공간(S1)이 형성됨으로써 엘이디램프(10)의 방열에 전원구동부(20)의 열기가 지장을 주지않을 뿐만 아니라 상대적으로 방열부하가 적은 제2케이싱(50)이 방열핀(51)을 구비하고 제1케이싱(30)과 열교환 가능하게 긴밀하게 결합됨으로써 연결기둥(P)에 형성되는 방열핀(F) 및 제2케이싱(50)으로 제1케이싱(30)의 열이 전달되어 엘이디램프를 위한 방열성능이 현저히 향상된다.As such, the first casing 30 for dissipating the LED lamp and the second casing 50 for the power driving unit are separated from each other, and the connection pillar P and the concave space S1 are formed therebetween so that the LED lamp 10 The heat dissipation of the power source drive unit 20 does not interfere with heat dissipation, and the second casing 50 having a relatively low heat dissipation load has a heat dissipation fin 51 and is closely connected to the first casing 30 so as to exchange heat. By being coupled, the heat of the first casing 30 is transferred to the heat dissipation fins F and the second casing 50 formed on the connection pillar P, thereby significantly improving the heat dissipation performance for the LED lamps.

또한, 전원구동부용 제2케이싱(50)이 엘이디램프용 제1케이싱(30)으로부터 분리 이격됨으로써 제1케이싱(30)의 상면과 연결기둥(P) 및 제2케이싱(50)의 하방에 방열핀(F) 형성이 가능하여 방열성능이 더욱 증대된다.In addition, since the second casing 50 for the power driver is separated from the first casing 30 for the LED lamp, the heat dissipation fins are disposed below the upper surface of the first casing 30 and the connection column P and the second casing 50. (F) formation is possible and heat dissipation performance is further increased.

본 발명은 여기에 더하여, 제1케이싱(30)의 램프설치부(311)를 둘러싸는 주벽(317)에 방사상으로 베이스방열핀(312)이 형성되고 수직관형태의 방열테(318)가 구비됨으로써 방열테(318)와 주벽(317) 사이에 자연대류를 촉진시키는 관형 공기통로(316)를 형성하는 구성이 방열성능을 획기적으로 향상시킨다.In addition to the present invention, the base heat radiation fins 312 are radially formed on the circumferential wall 317 surrounding the lamp installation portion 311 of the first casing 30 and the heat radiation frame 318 in the form of a vertical tube is provided. The configuration of forming a tubular air passage 316 that promotes natural convection between the heat dissipation frame 318 and the circumferential wall 317 significantly improves the heat dissipation performance.

즉, 제1케이싱(30)에 방사상으로 수직의 공기통로(316)가 형성되어 도 5에 도시된 바와 같이 자연대류가 이루어짐으로써 제1케이싱(30) 내의 열기정체를 방지하는 동시에 공기통로를 통하여 상승되는 공기가 상기 요입공간(S1)의 공기 이동에도 영향을 미쳐 제1케이싱(30)의 상면과 연결기둥(P)의 방열핀(F) 및 제2케이싱(50) 하방의 열기정체를 방지하고 이 부분을 포함하는 전체 외표면이 유효방열면으로 작동하여 방열이 신속하게 이루어지는 열 방출시스템을 구축하게 된다.That is, a radially vertical air passage 316 is formed in the first casing 30 so that natural convection is performed as shown in FIG. 5, thereby preventing thermal stagnation in the first casing 30 and through the air passage. The rising air also affects the air movement of the concave space (S1) to prevent heat stagnation below the heat dissipation fin (F) and the second casing (50) of the upper surface of the first casing (30) and the connection column (P). The entire outer surface including this part acts as an effective heat dissipation surface, thereby establishing a heat dissipation system in which heat dissipation is rapidly performed.

다시 말하면, 상기 수직의 공기통로(316)가 더운 공기를 상승시키고 상온의 공기를 계속적으로 유입시키는 자연대류를 유도하여 방열핀 사이에 열기가 정체되는 것을 방지하고 방열이 신속하게 이루어진다.In other words, the vertical air passage 316 raises hot air and induces natural convection to continuously introduce air at room temperature, thereby preventing heat from stagnation between the heat dissipation fins and rapidly dissipating heat.

또한, 엘이디램프(10)가 동심원상으로 연속배열될 경우 배열 중심부의 방열이 지체되는데 방열핀(F)이 형성된 연결기둥(P)이 제1케이싱(30)의 중심부에 형성됨으로써 엘이디램프 전체의 방열이 균일 신속하게 수행된다.In addition, when the LED lamp 10 is continuously arranged concentrically, the heat dissipation of the center of the array is delayed. The connection column P having the heat dissipation fins F is formed at the center of the first casing 30, thereby dissipating the entire LED lamp. This uniformity is performed quickly.

또한, 결합부에 오링(35) 설치 및 서멀 에폭시 시일링 등을 수행함으로써 외부의 폭발성 가스에 인화될 우려가 없다.In addition, the O-ring 35 is installed in the coupling portion and thermal epoxy sealing is performed to prevent the flammable gas from being ignited by the external explosive gas.

이상과 같이, 본 발명은 방폭등을 엘이디램프를 이용하여 구성함으로써 케이싱이 경량 소형화되어 제조비용이 현저히 절감되고 취급 관리가 간편함과 아울러 엘이디램프와 전원구동부의 케이싱이 제1케이싱과 제2케이싱으로 분리형성되어 연결기둥(P)을 매개로 이격 배치되고, 자연대류 촉진 및 열기정체를 방지하는 공기통로가 형성됨으로써 엘이디램프의 과제인 방열성능을 충분히 확보하여 조도를 유지하면서 수명을 극대화시킨다.As described above, according to the present invention, the explosion-proof lamp is configured by using an LED lamp, the casing is reduced in weight and weight, and thus the manufacturing cost is significantly reduced, and the handling and management are easy. In addition, the casing of the LED lamp and the power drive unit is used as the first casing and the second casing. Separation is formed to be spaced apart through the connecting column (P), and the air passage to prevent natural convection and thermal stagnation is formed to ensure sufficient heat dissipation performance of the LED lamp to maximize the life while maintaining the roughness.
