자연대류식 방열기능을 갖는 가로등기구Street light fixture with natural convection heat dissipation
본 발명은 자연대류식 방열기능을 갖는 가로등기구에 관한 것으로, 더욱 상세하게는 별도로 냉각장치를 설치하지 않고서도 자연대류방식으로 방열이 이루어지도록 가로등기구를 형성하고, 가로등기구를 상부케이스와 하부케이스 및 엘이디모듈부로 구성되게 하여 단순한 구조로 형성함으로써 제품의 용이한 분리결합으로 작업성 및 생산성을 높일 수 있게 되는 유체공학적인 자연대류식 방열기능을 갖는 가로등기구에 관한 것이다.The present invention relates to a street light fixture having a natural convection heat dissipation function, and more specifically, to form a street lamp mechanism so that the heat dissipation in a natural convection method without installing a separate cooling device, the upper and lower case And it consists of LED module unit to form a simple structure to the street lamp mechanism having a fluid engineering natural convection heat dissipation function that can increase the workability and productivity by easy separation and coupling of the product.
종래의 가로등 또는 보안등과 같은 조명장치는 주로 수은등이나 나트륨등을 광원으로 사용하여 조명을 하게 함으로써 밝기에 비하여 에너지 소비가 크다는 문제점과 수명이 짧아 시간경과에 따라 광량이 급격하게 저하되어 주기적인 관리가 필요하게 되었다.Conventional lighting devices such as street lamps or security lamps mainly use mercury lamps or sodium lamps as light sources to illuminate, resulting in high energy consumption compared to brightness and short lifespan. It became necessary.
특히 위에 열거한 가로등 또는 보안등은 수은가스를 이용하고 있으므로 폐기시 환경오염의 원인으로 작용하는 문제점을 갖고 있었다.In particular, the street lights or security lamps listed above use mercury gas, which has a problem of causing environmental pollution.
따라서, 최근에는 전력소모가 적고 수명이 긴 발광다이오드(LED)를 광원으로 사용하는 조명장치가 개발 출시되고 있다.Therefore, recently, a lighting device using a light emitting diode (LED) with low power consumption and long lifespan has been developed.
특히, 교통신호등이나 가로등과 같이 전력이 많이 소요되는 부분에 있어서는, 가로등에 많이 사용되는 나트륨등이나 수은등을 발광다이오드로 교체하게 되면 소비전력 절감효과는 매우 크다.In particular, in areas where power is consumed, such as traffic lights or street lights, replacing sodium or mercury lamps, which are frequently used in street lights, with light emitting diodes can greatly reduce power consumption.
그런데 종래의 발광다이오드를 이용한 조명장치는 자체에서 발생되는 열을 방열시키는 문제를 해결하는데 어려움이 있어 주로 저휘도 발광다이오드를 이용하고 있었다. 다시 말해 고휘도 발광다이오드를 이용할 경우 상당한 열이 발생하게 되는바 이 열에 의해 발광다이오드와 주변장치의 손상을 초래하게 되어 실질적으로 조명장치의 긴 수명에 치명적인 문제를 발생시킬 수 있다.However, a conventional lighting device using a light emitting diode has a difficulty in solving the problem of heat dissipation generated by itself, and mainly uses a low brightness light emitting diode. In other words, when a high brightness light emitting diode is used, considerable heat is generated, which causes damage to the light emitting diode and the peripheral device, which may cause a serious problem in the long life of the lighting device.
이와 같이 발광다이오드를 이용한 조명기구, 예를 들어, 발광다이오드 가로등은 일반 형광등의 가로등과는 달리 점등 회로가 단순하고, 인버터 회로와 철심형 안정기가 불필요하며, 전력 소모가 적고 수명이 길기 때문에 유지나 보수비용이 적은 장점이 있다.As described above, a light fixture using a light emitting diode, for example, a light emitting diode street light has a simple lighting circuit, a inverter circuit and an iron ballast are unnecessary, unlike a fluorescent lamp street lamp, and is low in power consumption and long in life. The advantage is low cost.
그러나, 이와 같은 발광다이오드 가로등의 단점으로는 열적 스트레스로 인한 특성 열화 및 고장이 발생한다는 측면이다.However, a disadvantage of such LED streetlights is that characteristics deterioration and failure due to thermal stress occur.
이는 발광다이오드를 동작시키기 위해 다수의 발광다이오드에 흐르는 전류가 높을수록 발생하는 열이 많아지기 때문에 고장 및 특성 열화가 발생하게 된다.The higher the current flowing through the plurality of light emitting diodes in order to operate the light emitting diodes, the more heat is generated, which leads to failure and deterioration of characteristics.
그래서 종래의 발광다이오드 가로등에서는 열전도성이 우수한 금속 물질을 이용한 히트 싱크(heat sink) 또는 슬러그와 같은 방열판을 장착하여 LED의 발광에 의한 열적 스트레스를 해소하고자 하고 있는 경우가 많으나, 이는 방열판을 구성하는 금속 물질의 한계성으로 인해 요구되는 방열 효율을 만족시키기 위해서는 방열판의 두께가 두꺼워지게 되므로, 발광다이오드 가로등의 크기 역시 증가하게 된다.Therefore, in the conventional LED street light, a heat sink such as a heat sink or slug using a metal material having excellent thermal conductivity is often installed to solve thermal stress caused by the light emission of the LED, but this constitutes a heat sink. In order to satisfy the heat dissipation efficiency required due to the limitation of the metal material, the heat sink has a thicker thickness, thereby increasing the size of the LED street light.
뿐만 아니라, 종래 발광다이오드를 이용한 가로등기구의 경우 그 특성상 밀폐를 유지시켜야만 외부로부터 습기의 유입을 차단할 수 있어 효율적인 방열을 위한 냉각장치의 설치가 곤란하며, 그렇다고 냉각장치를 설치하게 되면 가로등기구 내부로 외부에서 물이나 습기를 포함하여 각종 이물질이 유입될 우려가 있고, 또한 가로등기구 자체의 외관이 미려하지 않게 되는 등의 문제점이 있다.In addition, in the case of a street light fixture using a conventional light emitting diode, it is difficult to install a cooling device for efficient heat dissipation because it is necessary to maintain the airtight to block the inflow of moisture from the outside. Various foreign matters, including water or moisture, may flow from the outside, and the appearance of the street lamp itself may not be beautiful.
그리고, 엘이디를 이용한 가로등은 방열문제 외에도 엘이디 모듈로 침투되는 수분을 차단하기 위한 방수문제도 해결하여야 하는 숙제로 남아 있는 실정이며, 또한 대부분의 엘이디를 이용한 가로등이 복잡한 구조로 이루어져 있음에 따라 최대한 간단하고 단순한 구조로 가로등을 구성할 수 있는지 문제도 숙제로 남아 있다.In addition, the LED street light remains a problem to solve the problem of heat dissipation to block moisture penetrating into the LED module in addition to the heat dissipation problem, and also because most of the street light using LED has a complicated structure as simple as possible The question remains whether a street lamp can be constructed with a simple structure.
종래의 엘이디 모듈은 단순히 방열판에 장착된 기판을 외부와 단절시키기 위해 기판과 함께 빛이 투과되는 투광판을 하부케이스에 결합하는 단순 구조임에 따라 투광판과 하부케이스의 사이공간을 통해 수분이 침투하게 되면, 기판 및 엘이디에 직접적으로 영향을 주게 되어 부품의 파손을 가져오게 되는 문제점이 있었다.Conventional LED module is a simple structure that combines the light transmitting plate and the light transmitting plate together with the substrate to the lower case to simply disconnect the substrate mounted on the heat sink with the outside, the moisture penetrates through the space between the transparent plate and the lower case. In this case, there is a problem that directly affects the substrate and the LED, resulting in breakage of the component.
또한, 기판에 연결된 전선을 전원공급부와 연결시키기 위해 반사갓의 상측이나 측면을 통해 빼내도록 하고 있어 손쉽게 수분이 침투되는 등 방수 성능이 매우 낮았던 문제점이 있었다.In addition, the wire connected to the substrate to be pulled out through the upper or side of the reflection shade to connect with the power supply, there was a problem that the waterproof performance is very low, such as easily penetrated moisture.
