본 고안은 전구형 ＬＥＤ램프의 개량에 관한 것으로서, 더 구체적으로는, 히트싱크의 내부에 배치되는 ＳＭＰＳ모듈이 전기절연체로 둘러싸임으로써, 전기도체로 구성된 히트싱크와 ＳＭＰＳ모듈 사이가 전기(電氣)절연되어 ＬＥＤ램프의 안전성과 내구성이 종래보다도 더욱더 향상되도록 한 ＳＭＰＳ모듈 절연캡을 구비한 전구형 ＬＥＤ램프에 관한 것이다.The present invention relates to an improvement of a bulb type LED lamp, and more specifically, an SML module disposed inside the heat sink is surrounded by an electric insulator, so that a heat sink composed of an electric conductor and an SPM module are electrically connected. The present invention relates to a bulb type LED lamp having an SMPS module insulating cap that is insulated so that the safety and durability of the LED lamp are further improved than before.

형광등, 백열전구, 할로겐 램프, 보안등과 호환될 수 있도록 이들 재래식 조명기구와 동일 또는 유사하게 제작되는 ＬＥＤ램프는, 상술한 재래식 조명기구보다 사용수명이 길고, 에너지효율이 높아서 전력소비가 적으며, 스위치응답특성이 빠르다는 장점이 있다.LED lamps are manufactured in the same or similar way as conventional lamps so as to be compatible with fluorescent lamps, incandescent lamps, halogen lamps and security lamps. The switch response characteristic is fast.

그러나 ＬＥＤ램프의 제조분야에서, 아직까지는 ＬＥＤ램프의 제조비를 낮추거나 에너지효율을 높이는 데에만 연구의 초점이 맞춰져 있을 뿐, 실생활에서 중요하게 취급되는 전기(電氣)안전성과 내구성의 향상에 대한 연구는 이루어지지 않고 있다.However, in the manufacturing field of LED lamps, the research focuses only on lowering the manufacturing cost of LED lamps or increasing energy efficiency. However, researches on the improvement of electrical safety and durability, which are important in real life, Not done.

첨부된 도 5는 ＬＥＤ램프의 전기안전성과 내구성의 향상과 관련하여, 본 출원인이 선출원한 실용신안출원번호 20-2009-0012013에 기재된 '안정기 회로기판 보호용 절연벽을 구비한 ＬＥＤ램프'의 개략적인 구성을 나타낸 단면 사시도로서, 이후에 더 구체적으로 설명되는 본 고안의 기술적 특징에 대한 이해를 돕기 위한 것이다.FIG. 5 is a schematic diagram of an LED lamp having an insulating wall for protecting a ballast circuit board described in the Utility Model Application No. 20-2009-0012013 filed by the present applicant in connection with the improvement of the electrical safety and durability of the LED lamp. As a cross-sectional perspective view showing the configuration, to help understand the technical features of the present invention described in more detail later.

일반적으로, ＬＥＤ램프의 구성과 디자인은 제조사에 따라 그리고 제품에 따라 약간씩 차이가 있지만, 대체로, 도 5에 도시된 것처럼, 히트싱크(100), ＳＭＰＳ모듈(200), 전원접속유닛, ＬＥＤ모듈(500), 렌즈(600)를 필수구성요소로 포함하고 있다.In general, the configuration and design of the LED lamps vary slightly depending on the manufacturer and the product. However, as shown in FIG. 5, the heat sink 100, the SMPS module 200, the power connection unit, and the LED module are generally shown in FIG. 5. 500, the lens 600 is included as an essential component.

이들 중 히트싱크(100)는, 소재로 알루미늄이 주로 사용되는데, 다른 소재에 비해 가볍고, 열전도율이 우수하며, 가공하기가 쉽기 때문이다. 또한, 구조적인 면에서는, 중앙에 관통공(121)이 천공된 수평벽(120)과 이 수평벽(120)의 가장자리를 따라 일체로 형성된 둘레벽(110)에 의해 구획되는 수용공간(130)과, 이 수용공간에 내장되는 ＳＭＰＳ모듈(200)과 상기 수평벽 위에 배치되는 ＬＥＤ모듈(500)에 의해 발생한 열이 효과적으로 제거될 수 있도록 상기 둘레벽의 외면에 일체로 형성되는 다수의 냉각핀(111)으로 구성되어 있다. 한편, 도 5에 나타나 있는 히트싱크는, 둘레벽의 상단부에 림(140)이 일체로 형성되어 있지만, 이 림은 둘레벽에 대해 분리 가능한 링 형태로 제작되는 경우도 있다.Among these, the heat sink 100 mainly uses aluminum as a material, because it is lighter than other materials, has excellent thermal conductivity, and is easy to process. In addition, in the structural aspect, the receiving space 130 is partitioned by a horizontal wall 120 in which a through hole 121 is drilled in the center and a peripheral wall 110 integrally formed along the edge of the horizontal wall 120. And a plurality of cooling fins integrally formed on an outer surface of the circumferential wall to effectively remove heat generated by the SMPS module 200 embedded in the accommodation space and the LED module 500 disposed on the horizontal wall. 111). On the other hand, in the heat sink shown in Fig. 5, the rim 140 is integrally formed at the upper end of the circumferential wall, but the rim may be manufactured in the form of a ring detachable to the circumferential wall.

히트싱크의 하부에 결합되는 전원접속유닛(power source connection unit)은, 전력공급이 소켓을 통해 이루어지는 경우라면, 도 5에 도시된 것처럼, 플라스틱 사출성형물인 장착부재(300)의 하부측 나사부(310)에 금속베이스(400)가 나사결합방식으로 장착되는 베이스 타입으로 구성된다. 이와 달리, 만약 전력공급이 콘센트를 통해 이루어지는 경우라면, 일반적으로, 할로겐 램프에서 흔히 볼 수 있는 플러그 타입으로 구성된다.The power source connection unit coupled to the lower portion of the heat sink has a lower thread 310 of the mounting member 300, which is a plastic injection molding, as shown in FIG. 5, when power is supplied through the socket. ) Is composed of a base type in which the metal base 400 is mounted by screwing. In contrast, if the power supply is via an outlet, it is usually of a plug type commonly found in halogen lamps.

한편, 본 출원인은, 앞에서 언급한 실용신안출원번호 제20-2009-0012013호에서, 히트싱크의 수용공간(130)에 배치되는 ＳＭＰＳ모듈의 하부가 히트싱크에 대해 절연되도록 하고, ＳＭＰＳ모듈이 수용공간 내에서 움직이지 않도록 하기 위해, 도 5에 도시된 것처럼, 히트싱크(100)의 하단이 지지되는 플랜지(320)로부터 상기 나사부(310)와는 정반대의 방향으로 절연벽(330)이 돌출되고, 또한 절연벽의 내면(內面)에는 ＳＭＰＳ모듈의 양측 변부(邊部)가 끼워질 수 있는 지지채널(331)이 형성된 장착부재(300)를 제안한 바 있다.On the other hand, the present applicant, in the above-mentioned utility model application No. 20-2009-0012013, the lower part of the SSM module disposed in the receiving space 130 of the heat sink is insulated from the heat sink, the SPM module is accommodated In order not to move in the space, as shown in FIG. 5, the insulating wall 330 protrudes in the direction opposite to the screw portion 310 from the flange 320 on which the lower end of the heat sink 100 is supported, In addition, the mounting member 300 has been proposed on the inner surface of the insulating wall is formed with a support channel 331 to be fitted to both sides of the SSM module.

그렇지만, 이와 같은 구성에 의하더라도 ＳＭＰＳ모듈의 상부는 절연되지 않은 상태이기 때문에, 습도가 굉장히 높은 환경에서 장시간 사용되거나, 제조과정에서 발생할 수 있는 어떤 결함으로 인해, 이론적으로는 ＳＭＰＳ모듈과 히트싱크 사이에서 방전이 일어날 가능성이 있다.However, even with such a configuration, since the upper part of the SSM module is not insulated, it may theoretically be used between the SSM module and the heat sink due to a defect that may occur during a long time in an extremely high humidity environment or may occur during manufacturing. Discharge may occur at

아직까지는, 이와 같은 전기안전성의 문제가 대두하지 않았으나, 이론적으로는 ＳＭＰＳ모듈과 히트싱크 사이에서 방전이 일어날 수 있다.So far, such an electrical safety problem has not been raised, but in theory, discharge may occur between the SMPS module and the heat sink.

따라서 본 고안은 전기절연체로 만든 절연캡을 사용하여, ＳＭＰＳ모듈과 히트싱크 사이를 전기적으로 완전히 절연시킴으로써, 전기안전성에 관한 문제가 발생할 여지가 없고, 부차적으로는 ＬＥＤ램프의 내구성이 종래보다 향상될 수 있도록 한, ＳＭＰＳ모듈 절연캡을 구비한 전구형 ＬＥＤ램프를 제공하는데 목적이 있다.Therefore, the present invention uses an insulation cap made of an electric insulator, and electrically insulates the SSM module from the heat sink completely, so that there is no problem of electrical safety. Secondly, the durability of the LED lamp can be improved. It is an object of the present invention to provide a bulb type LED lamp having an SPM module insulation cap.

상술한 기술적 과제가 해결될 수 있도록, 본 고안에 따른 ＳＭＰＳ모듈 절연캡을 구비한 전구형 ＬＥＤ램프는, 수평벽의 가장자리를 따라 일체로 형성되는 둘레벽에 의해 수용공간이 형성되고 둘레벽의 외면에 복수의 냉각핀이 형성되는 히트싱크 와, 수평벽의 상면에 배치되는 ＬＥＤ모듈 과, 히트싱크의 상단부에 결합되어 ＬＥＤ모듈의 전방(前方)에 위치되는 렌즈 와, 히트싱크의 수용공간에 내장되는 ＳＭＰＳ모듈 과, ＳＭＰＳ모듈의 일부분이 히트싱크에 대해 절연될 수 있도록 전기절연체로 이루어진 절연벽이 히트싱크의 하부에 끼워짐으로써 히트싱크와 결합되는 전원접속유닛 과, 절연벽과 결합되어 ＳＭＰＳ모듈의 나머지부분이 히트싱크에 대해 절연될 수 있도록 히트싱크의 수용공간에 끼워지는 절연캡 을 포함하여 구성되는 것을 특징으로 한다.In order to solve the above-described technical problem, the bulb-type LED lamp having an SSM module insulating cap according to the present invention, the receiving space is formed by the peripheral wall integrally formed along the edge of the horizontal wall and the outer surface of the peripheral wall A heat sink having a plurality of cooling fins formed therein, an LED module disposed on an upper surface of the horizontal wall, a lens coupled to an upper end of the heat sink and positioned in front of the LED module, and embedded in the heat sink accommodation space. A power connection unit coupled to the heat sink by inserting an insulating wall made of an SSM module , an electrical insulator so that a portion of the SSM module can be insulated from the heat sink, and coupled to the heat sink; And an insulating cap fitted to a receiving space of the heat sink so that the rest of the heat sink can be insulated from the heat sink. It is done.

또한, 본 고안의 일 실시형태에서, 상술한 절연캡은, 절연벽과의 결합부분에 계단형상부가 더 형성되어 있어, 절연캡과 절연벽의 결합부분에 대해, 추가로 씰링할 필요가 없다.In addition, in one embodiment of the present invention, the above-described insulating cap is further formed in a stepped portion in the coupling portion with the insulating wall, it is not necessary to seal additionally for the coupling portion of the insulating cap and the insulating wall.

본 고안에 따른 ＳＭＰＳ모듈 절연캡을 구비한 전구형 ＬＥＤ램프에 의하면, 본 고안의 특징적 구성요소인 절연캡과 장착부재의 절연벽에 의해 ＳＭＰＳ모듈과 히트싱크 사이가 전기적으로 완전히 절연되므로, 열악한 환경에서 ＬＥＤ램프를 장시간 사용한다든지 제조과정에서 발생한 어떤 결함을 ＬＥＤ램프가 갖고 있는 경우에도 ＳＭＰＳ모듈과 히트싱크 사이에서는 방전이 일어날 수 없으므로, 전기안전성에 관한 문제가 발생할 여지가 없고, 부차적으로, ＬＥＤ램프의 내구성이 종래보다 현저히 향상될 수 있다.According to the bulb type LED lamp having the SMPS module insulation cap according to the present invention, since the insulation cap and the insulating wall of the mounting member, which are characteristic components of the present invention, are completely electrically insulated between the SMPS module and the heat sink, the environment is poor. Even if the LED is used for a long time or the LED has any defects in the manufacturing process, no discharge can occur between the SMPS module and the heatsink, so there is no room for electrical safety problems. The durability of can be significantly improved than before.
