Claim 2:
3. A retroreflective structure comprising:
a retroreflective film (230) located at a lower portion; and
a transparent light transfer body (250) mounted on the upper surface of the retroreflective film (230),
wherein the light transfer body (250) emits light by receiving power or a light source from a switch unit (100),
wherein the retroreflective film (230) retroreflects light emitted from the light transfer body (250) so that the retroreflected light passes through the light transfer body (250) and is emitted outwards,
wherein the light-emitting safety band comprises:
a switch unit (100) connected with a light source (L) to supply power; and
a light-emitting unit (200) coupled to the switch unit (100),
wherein the switch unit (100) includes: a middle plate case (110) having a light transfer body insertion hole (112) formed thereon; an upper plate case (130) coupled to the upper portion of the middle plate case (110); and a PCB (120) inserted into the middle plate case (110) and the upper plate case (130),
wherein the light-emitting unit (200) includes: a lower retroreflective film (230); and a light transfer body (250) mounted to be forced against the upper portion of the retroreflective film (230),
wherein the light transfer body (250) includes an insertion hole (258) formed at an end portion thereof, and the light source (L) is inserted into the insertion hole (258), and
wherein if the light source (L) emits light, the light transfer body (250) emits light upwards, downwards, leftward and rightwards, and the retroreflective film (230) retroreflects light emitted downwards by the light transfer body (250) such that the retroreflected light passes through the light transfer body (250) and is emitted outwards.
