본 발명은 탈착식 방열 판을 적층 시켜 방열부를 구성하는 투광등 형태의 LED 조명등에 관한 것으로, 더욱 구체적으로는 외부 조건에 따라 조명등 몸체에 장착되는 탈착식 방열 판의 수를 조절함으로써 최적의 냉각 효과를 보장할 수 있도록 한 탈착식 방열 판을 가지는 LED 조명등에 관한 것이다.The present invention relates to a LED lamp of the floodlight type to form a heat dissipating unit by stacking a removable heat dissipation plate, more specifically to ensure the optimum cooling effect by adjusting the number of removable heat dissipation plate mounted on the lamp body according to external conditions The present invention relates to an LED lamp having a removable heat sink.

LED(Light Emitting Diode, 발광다이오드)는 전압을 인가하면 빛이 발광(發光) 되는 반도체의 일종으로써, 전력 소모가 적고 수명이 길며 다양한 색상의 빛을 구현할 수 있는 친환경적인 광원이라는 장점이 있다. 하지만, 열에 취약하기 때문에 LED 소자의 구동 온도가 60도 이상이 되면 LED 소자의 열화가 일어나게 된다. 따라서 LED 소자를 조명등에 적용하기 위해서는 LED 소자에서 발생하는 열을 효과적으로 냉각할 수 있는 방열 시스템이 반드시 갖추어져야만 한다.LED (Light Emitting Diode) is a kind of semiconductor that emits light when voltage is applied, and it has the advantage of being an eco-friendly light source that can realize light of low power consumption, long life and various colors. However, since it is vulnerable to heat, deterioration of the LED element occurs when the driving temperature of the LED element exceeds 60 degrees. Therefore, in order to apply the LED element to the lamp, a heat dissipation system that can effectively cool the heat generated from the LED element must be equipped.

하지만, LED 조명등이 설치되는 장소에 따라 요구되는 방열 조건 역시 각기 달라지기 때문에 어떤 경우에는 실제 필요한 방열 효과보다 큰 방열 능력을 가지는 방열 시스템이 조명등에 장착되고, 또 다른 경우에는 장착된 방열 시스템의 방열 능력이 부족하여 LED 소자에서 발생하는 열을 제대로 빼주지 못하게 되는 경우가 발생하고 있는 실정이다.However, since the heat dissipation requirements are also different depending on where the LED lamp is installed, in some cases a heat dissipation system having a greater heat dissipation capacity than the actual heat dissipation effect is mounted on the lamp, and in other cases, heat dissipation of the mounted heat dissipation system. There is a case that the lack of ability to properly remove the heat generated from the LED device.
