The present invention relates to an LED light emitting apparatus having a heat dissipation unit with a structure capable of forcibly receiving and discharging fluid to effectively dissipate heat generated by an LED module and a control module. The LED light emitting apparatus comprises: the LED module which emits light; a first housing having an installation unit on which the LED module is installed; a control module which drives the LED module; a second housing which has the control module installed therein, has an installation space, and is joined to the first housing; and the heat dissipating unit which is formed between the first housing and second housing and dissipates heat generated by the LED module and control module. According to the LED light emitting apparatus, heat, generated by the LED module and the control module, can be dissipated by forced convection. The heat can be dissipated in a more effective manner than a heat dissipation scheme relying on natural convection. The LED light emitting apparatus has a merit of dissipating, in an effective manner, not only the small quantity of heat generated by an LED module for a simple lighting but also a large quantity of heat generated by a high-power LED module. 본 발명은 LED모듈과 제어모듈에서 발생하는 열을 효과적으로 방열하기 위해 강제로 유체가 출입될 수 있는 구조의 방열부가 구비된 LED발광장치에 관한 것으로, 광을 출사하는 LED모듈과, LED모듈이 장착되는 장착부를 가지는 제1하우징과, LED모듈을 구동시키기 위한 제어모듈과, 제어모듈이 설치되고 장착공간을 가지며 제1하우징과 결합되는 제2하우징과, 제1하우징과 제2하우징의 사이에 형성되어 LED모듈과 제어모듈에서 발생되는 열을 방열하기 위한 방열부를 구비한다. 이러한 LED 발광장치에 의하면, 강제대류에 의해 LED모듈과 제어모듈에서 발생하는 열을 방열하는 것이 가능하며 자연대류에 의한 방열방식보다 더 효과적으로 열을 방열할 수 있으며 열량이 낮은 단순 조명용 LED모듈에서뿐만 아니라 고출력 LED모듈에서 발생하는 많은 열량을 효과적으로 방열할 수 있는 장점이 있다.
