Abstract
(EN)
The present invention improves the cooling efficiency of a light-emitting unit of a floodlight, the light-emitting unit being covered with a balloon. The present invention comprises: a body part (10) having a light-emitting unit; a battery (13) provided within the body part; a balloon (7) covering the light-emitting unit and covering a portion of the body part (10); a heat sink (25) for cooling the light-emitting unit; intake ports (41) that take in outside air; a fan (30) that blows air taken in from the intake ports (41) to the heat sink; and discharge ports (42) for discharging air that has passed through the heat sink. The heat sink, the fan, and the battery are arranged on a straight line in the vertical direction of the body part. The discharge ports (42) open into the balloon (7).
