The present invention is applicable to the field of bicycle motion protection and safeguard equipment. The present invention discloses a light emitting helmet, including a helmet main body and a light emitting lamp band, a fixing groove is formed in the surface of the helmet main body, a through hole is formed in the fixing groove, the light emitting lamp band is provided with a control line, the light emitting lamp band is fixed in the fixing groove through a fixing mechanism, and when the light emitting lamp band is fixed, the control line is in signal connection with a controller by penetrating through the through hole. As the light emitting lamp band is fixed in the fixing groove, the control line of the light emitting lamp band forms the signal connection with the controller by penetrating through the through hole. Even if damage occurs, the light emitting lamp band can be singly repaired in the production process, thereby avoiding the problems that the light emitting lamp band arranged in the helmet main body cannot be repaired when a fault occurs, and that arrangement of the lead of the light emitting lamp band is complex in the forming process, and reducing the production cost and the forming difficulty of the light emitting helmet.
