Description

엘이디 방폭등{EXPLOSION FREE LAMP WITH LED} LED explosion proof, such as {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 open the housing is light-weight compact to be produced cost savings and handling management, simplicity and well as the casing of the LED lamp and the power drive unit is formed spaced apart arrangement by a connecting post parameters while facilitating natural convection and by employing a LED lamp fixture the air passage is formed to prevent the support by being a sufficient heat dissipation performance of the LED lamp of extreme heat or the like relates to explosion-proof LED that maximizes the life and intensity.

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. Generally, the usual way to prevent explosions is so necessary, but in reality can not be isolated in the ignition source for flammable gas is present when using electrical equipment in a hazardous atmosphere to isolate the source of ignition due to the presence of explosion hazards due to electrical sparks or isolated that and use the explosion-proof electrical equipment.

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. This prior art 100 of the explosion-proof, such as industrial lighting device as one of the explosion-proof electrical equipment, as shown in Figure 6, the lamp having a glass sphere (球), such as a high pressure mercury lamp, high pressure sodium lamp, a metal halide lamp ( 110) is provided with a, is provided with a pressure-resistant casing 130, which prevent the explosion of the lamp due to overheating in case of spark lead to secondary explosions.

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 is likely to be superimposed on the outer explosive gases through the pressure has, joint surfaces, opening, such as a vessel when an explosive gas or vapor explosion by electrical spark of the lamp to withstand the pressure in the container this confidentiality is not 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. Thus, the explosion-proof casing and the like are in a solid structure that a casing main body 131 is of a metallic material glass globe 132 is to be tightly binding structure is a glass globe 132 has the outer protective net 133 is formed.

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. Further, the lamp 110 as made of an type having a glass spheres, glass globe 132 is to secure sufficient internal space to accommodate the glass spheres, have the pressure of the breakout force at the time of glass beads blast so that the total thickness of the casing including a thick glove size is configured to prevent explosion of the large heavy form.

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. Such a prior art, so the lamp is open to the light, so by the emission characteristic is caused spark occurrence is frequent heat lamp replacement frequency, and the lamp replacement, the need to open the casing of the massive structure, lamp replacement and handling this was a very difficult problem.

한편, 엘이디의 경우에는 열발광이 아닌 반도체의 pn 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, when the LED is creating a minority carrier (electron or electron hole) injected by using a pn-junction structure of a semiconductor non-thermal emission, the spark occurs in the lamp due to heat by light emission is yirueojim by their recombination (再 結合) almost no risk, therefore, if using the LED lamp configuration for explosion-proof and so on will be a strong pressure-resistant structure required to enable the miniaturization and weight reduction.

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 Figure 7 to the prior art, explosion proof, etc. description 201 using the LED lamp 202, 203 is disclosed, but mothayeo not support the heat radiation performance, such as a LED lamp and a power drive unit that is installed in a one-piece housing and the intensity decreases sharply there is a problem in that the life is shortened.
