공기 순환식 LED 조명등기구{LED lighting device having air circulation type}LED lighting device having air circulation type

본 발명은 공기 순환식 LED 조명등기구에 관한 것으로서, 간단한 구조로 지지대의 암에 LED 조명등기구를 장착하여 작업효율을 높이고, LED의 발열을 방열핀과 방열판을 통해 열을 이동시켜 신속히 방열시킴과 동시에 전면 ·후면 개방부와 순환홀을 통해 공기 순환에 의한 대류현상으로 내부 열을 신속히 외부로 배출시켜 방열효과를 극대화하는 공기 순환식 LED 조명등기구에 관한 것이다.The present invention relates to an air-circulating LED light fixture, which is equipped with an LED light fixture on the arm of the support in a simple structure to increase work efficiency, and quickly dissipate heat by moving heat through the heat sink fins and heat sink. · It relates to an air-circulating LED light fixture that maximizes heat dissipation effect by quickly discharging internal heat to the outside through convection caused by air circulation through the rear opening and the circulation hole.

현대 조명의 메카로 불리는 LED 가로등 및 보안등은 고효율 조명등으로 자리매김하고 있다. LED street lights and security lights, called mecca for modern lighting, are becoming highly efficient lighting.

발광 다이오드(LED)는 p형과 n형 반도체의 접합으로 이루어져 있으며 전압을 가하면 전자와 정공의 결합으로 반도체의 밴드 갭(band gap)에 해당하는 에너지를 빛의 형태로 방출하는 일종의 광전자 소자이다. 발광 다이오드는 정보·통신 기기를 비롯한 전자 장치의 표시·화상용 광원으로 이용되어 왔으며, 발광 다이오드(LED)는 일반 조명등, 건물 장식등, 무드(mood)등, 차량등, 교통 신호등, 실내 및 실외 전광판, 유도등, 경고등, 각종 보안장비용 광원, 살균 또는 소독용 광원 등에 폭넓게 활용되고 있다.A light emitting diode (LED) is a type of optoelectronic device that consists of a junction of a p-type and an n-type semiconductor, and emits energy corresponding to a band gap of the semiconductor in the form of light by combining electrons and holes when a voltage is applied. Light emitting diodes have been used as light sources for display and image of electronic devices including information and communication devices, and light emitting diodes (LEDs) are general lighting, building decoration lights, mood lights, vehicle lights, traffic lights, indoor and outdoor It is widely used in electric signs, induction lights, warning lights, light sources for various security equipment, and light sources for sterilization or disinfection.

광원의 핵심소자인 발광다이오드는 전자와 정공의 전류흐름으로 LED에는 광원이 나오지만 반대쪽인 LED 칩에서는 높은 열이 발생되어 효과적인 방열기술 없이는 고효율 조명등을 제작할 수 없다.The light-emitting diode, which is a core element of the light source, emits light from the LED due to the current flow of electrons and holes, but high heat is generated from the LED chip on the other side, so it is impossible to manufacture a high-efficiency lighting lamp without effective heat dissipation technology.

LED 조명등은 모두가 아래 바닥을 향해 조명이 이루어지는 것이 일반적이다. 이때 인쇄회로기판(PCB) 크기만큼의 방열판이 열을 받아 방열핀에서 열을 식히는 구조로 구성되어 있다. 이러한 방열 구조는 LED 모듈에서 발생되는 열이 LED 주변 PCB까지 전달되어 넓은 방열판에 전해져 상승으로 올라가며 열이 방출되어 식혀줘야 한다.It is common for the LED lamps to all be illuminated toward the bottom. At this time, the heat sink of the size of the printed circuit board (PCB) receives heat and is configured to cool the heat in the heat sink fins. In such a heat dissipation structure, heat generated from the LED module is transmitted to the PCB around the LED, transmitted to a wide heat sink, and ascends upward, and heat must be released to cool.

또한, LED 조명등기구는 높은 지지대에서 작업을 하기 때문에 제품이 무겁거나 장착 구조가 복잡하면 작업 효율이 많이 떨어지는 문제점이 있었다.In addition, since the LED light fixture works on a high support, there is a problem in that the work efficiency is greatly reduced when the product is heavy or the mounting structure is complicated.

종래의 LED 케이스는 하중이 커서 제품의 경량화가 어려우며, 부식, 빛 습도 등 외부 환경적 요인에 의한 내후성 및 내충격성이 약하여 LED 케이스 보호, 내부의 LED모듈 및 각종 부품들을 효과적으로 보호할 수 없었으며, 설치함에 있어서 어려운 문제점이 있었다.The conventional LED case has a large load, so it is difficult to reduce the weight of the product, and the weatherability and impact resistance due to external environmental factors such as corrosion and light humidity are weak, so it is not possible to effectively protect the LED case, the internal LED module and various parts, There was a difficult problem in the installation.

한편, LED를 이용한 조명기구는 작동시 고출력 LED에서 발생하는 열을 효과적으로 냉각시키지 못하여 순전압이 떨어지고 발광효율이 저하되며, 수명이 짧아지게 되는 문제점이 있었다.On the other hand, the lighting equipment using LEDs has a problem in that the heat generated by the high-power LED during operation is not effectively cooled, so that the net voltage falls, the luminous efficiency decreases, and the life span becomes short.
