The invention discloses a light-emitting character and a manufacturing method thereof. A housing of a typeface of the light-emitting character is provided with a folding edge which folds inward, the folding edge is in a wavy shape, and is arranged to tilt downward, and resin is poured on a panel to form the resin layer; several artificial crystals are embedded on the resin layer, and are embedded along the edge of the resin layer. An LED chip on a light source plate in the light-emitting character is arranged to be multiple light-emitting chains, and a new control system is designed to control the sequence of the light-emitting chains. According to the light-emitting character and the manufacturing method thereof, the folding edge plays the role of fastening, sealing and light emitting, the artificial crystals refract unique colorful halo, and the control system guarantees the heat dissipation of the light source plate, and makes the service duration of all the light emitting chains tend to be identical. The light-emitting character is good in waterproofing and excellent in heat dissipation, the service life of the light-emitting character can be drastically prolonged, and the light-emitting character can be utilized for a long time after being put into use at one time.
