To use high speed downward flow of a rotor for forced cooling of LEDs to efficiently cool the LEDs with a radiator which achieves downsizing and weight saving and light a location requiring lighting by a drone having a light payload for a long time.SOLUTION: In a lighting device, an illuminator 2 which uses LEDs 7 as a light source 3 is disposed below a drone body 1. Further, heat radiation fins 41 of a radiator 4 thermally coupled to the LEDs 7 are disposed in a downward flow area 8 of a rotor 11 to use downward flow of the rotor 11 for a ventilation mechanism of the LEDs 7 and thereby efficiently cool the LEDs 7.SELECTED DRAWING: Figure 2
【課題】ローターの高速下降流をＬＥＤの強制冷却に併用して小型で軽量化された放熱器でＬＥＤを効率よく冷却して、ペイロードの軽いドローンで必要な場所を長時間明るく照射する。【解決手段】照明装置は、ドローン本体１の下方に、光源３をＬＥＤ７とする照明器２を配置して、ＬＥＤ７に熱結合している放熱器４の放熱フィン４１をローター１１の下降流領域８に配置して、ローター１１の下降流をＬＥＤ７の送風機構に併用してＬＥＤ７を効率よく冷却する。【選択図】図２
