ABSTRACT:
A light-emitting warning device of a safety helmet, including a helmet main body, a light guide element and a light source control mechanism. An annular locating groove and a receiving cavity are formed on an outer face of the helmet main body. Two end sections of the locating groove communicate with the receiving cavity via two through holes formed in the helmet main body. An elongated flexible strip body is received in the locating groove. Two end sections of the light guide element extend through the through holes into the receiving cavity to connect with the light source control mechanism. The light source control mechanism projects light into the light guide element, and emits as a lighting ring along the periphery of the helmet main body. The light guide element communicates with an interior of the helmet main body to avoid dropping.
