본 발명은 방열하우징에 보조방열부재의 탈착이 자유롭게 구성됨으로써 엘이디 조도 및 입력전력(W)의 증대 설계변경시 임의로 보조방열부재를 추가하고 또한 추가 개수를 조정할 수 있어 기본 설계안에서부터 증대 설계변경되는 고 입력전력(W)을 수용하는 범위에 이르기까지 단일한 방열하우징을 방열 신뢰성을 확보하며 범용적으로 이용할 수 있도록 하는 방열성능 조정이 가능한 엘이디 조명기구에 관한 것이다.According to the present invention, the auxiliary heat dissipation member can be freely attached to the heat dissipation housing, so that the auxiliary heat dissipation member can be arbitrarily added and the number of additional adjustments can be made at the time of design change of the LED roughness and input power (W). The present invention relates to an LED luminaire capable of adjusting heat dissipation performance to ensure a single heat dissipation housing to a range that accommodates input power (W) to ensure heat dissipation reliability and to use it universally.

엘이디(LED: Light Emitting Diode)는 종래의 광원에 비하여 소형이고 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 전력이 적게 소모되어 에너지 효율이 우수한 고광도를 발하는 특장점으로 조명기구의 광원으로 다양하게 개발되고 있다.LED (Light Emitting Diode) is a feature that emits high brightness with high energy efficiency because it consumes less power because electric energy is directly converted to light energy, and it is small and longer than conventional light sources. It is developed variously.

한편으로 엘이디는 점등시 열이 발생되고, 방열이 원활하게 되지 못할 경우 조도가 급격히 저하될 뿐만 아니라 수명이 현저히 단축되므로 상기 장점을 갖는 엘이디 조명기구의 품질특성은 방열성능에 의하여 좌우된다고 할 수 있어 이에 대한 연구개발이 다각도로 진행되고 있다.On the other hand, when the LED is turned on, heat is generated, and if the heat dissipation is not smooth, not only the illuminance is drastically reduced but also the life is remarkably shortened. Therefore, the quality characteristics of the LED lighting device having the above-mentioned advantages are dependent on the heat dissipation performance. R & D is progressing in various ways.

엘이디 조명기구에서 방열부는 엘이디 실장 피씨비가 장착되는 하우징의 일부로 형성되며 방열부를 갖는 하우징의 설계는 조명 발열량에 따라 대응하여 설계되고 조명 발열량은 1개 엘이디의 입력전력(W) 및 엘이디의 수량에 따라 결정된다.In the LED lighting fixture, the heat dissipation part is formed as a part of the housing in which the LED mounting PC is mounted, and the design of the housing having the heat dissipation part is designed according to the heat generation amount of light, and the light heat amount is determined according to the input power (W) of one LED and the quantity of LEDs.
