DRONE-MOUNTED LIGHTING DEVICE HAVING HEAT-RADIATING PORTION PROVIDED ON GIMBAL
Document Type and Number:
WIPO Patent Application WO/2019/050342
Kind Code:
A2
Abstract:
The present invention relates to a drone-mounted lighting device having a heat-radiating portion mounted on a gimbal, wherein light is emitted in the air above an area to be illuminated, thereby minimizing the unilluminated area caused by shadows, the illuminated area can be easily varied without rotating or tilting the drone, and the heat-radiating efficiency can be increased by using the downward air stream from propellers, thereby reducing the weight of the heat-radiating structure. More particularly, the present invention relates to a drone-mounted lighting device configured such that the same is mounted on a drone and can emit light in the air, the drone-mounted lighting device comprising: a mounting portion mounted on the lower side of the drone; a swing portion coupled to the mounting portion and driven to rotate leftward/rightward; a tilting portion coupled to the other end of the swing portion and driven to rotate upward/downward; and a lighting portion mounted on the tilting portion such that the emission direction is varied according to rotation driving of the swing portion or the tilting portion, wherein the swing portion is provided with a first auxiliary heat-radiating portion comprising a plurality of heat-radiating plates to which heat generated by the lighting portion is conducted, and which radiate the heat, and the tilting portion is provided with a second auxiliary heat-radiating portion comprising a plurality of heat-radiating plates to which heat generated by the lighting portion is conducted, and which radiate the heat.
