Abstract

A rotary lantern with added waterproof performance according to one embodiment of the present invention comprises: a body portion having a first rotational coupling surface formed at an angle at an end; a head portion having a second rotational coupling surface formed at an angle at an end that corresponds to and contacts the first rotational coupling surface; a protrusion formed to protrude from either the first rotational coupling surface or the second rotational coupling surface; an insertion portion formed on the other of the first rotational coupling surface or the second rotational coupling surface where the protrusion is not formed; a fixing pin that selectively restricts the rotation of the protrusion while fastened to the body portion through a pin insertion hole; a control circuit portion that supplies power to the head portion and controls driving through the protrusion while embedded in the body portion; and a light-emitting portion provided in the head portion that emits light under the control of the control circuit portion; wherein the rotary lantern comprises: a first waterproof portion for waterproofing the gap between the first rotational coupling surface and the second rotational coupling surface; a second waterproof portion for waterproofing the control circuit portion; and a third waterproof portion for waterproofing the pin insertion hole into which the fixing pin is inserted.
