The present invention relates to a light emitting diode lighting tool to grow a stem plant. More specifically, an air feeding and ventilating guide is installed in the center in the lighting tool equipped with a ventilating fan to radiate heat generated from LEDs, such that indoor air can easily be suctioned or heat in the tool can be diffused to the side of a growing plant. Also, specific temperature sensors are respectively installed inside and outside of the lighting tool. Accordingly, if an indoor temperature around the growing plant is higher than 37±2°C in a state wherein the temperature in the lighting tool is 45-60°C due to the heating of the LEDs, the ventilating fan is operated in order to feed indoor air to be discharged to the outside through an air exhausting mode (upward), such that heat in the lighting tool is radiated. When the indoor temperature around the growing plant is less than 37±2°C in a state wherein the temperature in the lighting tool is 45-60°C, heat in the lighting tool is discharged in a form of a warm air towards the growing plant. When the temperature in the lighting tool is less than 45-60°C, the operation of the ventilating fan is blocked. Consequently, the radiating function of the lighting tool can actively be performed, and a small quantity of heat is generated, such that the lighting tool can access the plant, has high optical efficiency, and can actively irradiate light to grow the plant (photosynthesis). Warm air heating is possible using waste heat generated in the lighting tool, such that unnecessary heating costs can remarkably be reduced.COPYRIGHT KIPO 2014본 발명은 줄기식물 재배용 발광다이오드 조명기구에 관한 것으로 특히, LED들에서 발생되는 열을 방열하기 송풍팬이 구비된 조명기구 내 중앙부에 실내 공기를 원활히 흡입하거나 또는 기구 내의 열기를 작물 측으로 확산시켜 줄 수 있도록 하는 공기 흡입 및 송풍 가이드를 설치하고, 조명기구의 내부 및 외부에는 각각 소정의 온도센서를 설치하여 LED들의 발열로 인한 조명기구 내부의 온도가 45~60℃ 사이인 상태에서 작물 주변의 실내 온도가 37±2℃보다 높으면 실내공기를 흡입하여 외부로 배출시키는 배기방식(상향)으로 송풍팬을 구동시켜 조명기구 내부 열을 방열시키고, 조명기구 내부의 온도가 45~60℃ 사이인 상태에서
