The invention applies to the field of safety helmets, and discloses a luminous helmet. The luminous helmet comprises a helmet body which is composed of a partial transparent outer layer and a damping inner layer and FPC boards which are arranged between the outer layer and the inner layer, each FPC board is provided with one or more LED lamps, and transparent protrusions which protrude outwards are arranged on the portions, corresponding to the LED lamps, of the outer layer. The method comprises the steps that a PC piece is put into a mold, plastic sucking molding is conducted on the PC piece to form the outer layer with the transparent protrusions, each FPC board with one or more LED lamps is fixed on the corresponding transparent protrusion, the outer layer which is fixed with the FPC boards with the LED lamps are arranged in a molding mold, inner layer EPS materials are pressed in the molding mold to form the helmet of which the inner layer is in joint connection with the outer layer through pressure injection. Due to the fact that the transparent protrusions can just contain the LED lamps, the gap between the FPC board which is close to the LED lamps and the outer layer is small, when the inner layer materials are formed through pressure injection at the high temperature and under the high pressure, the rupture phenomenon of FPC boards is not prone to occurrence, the production efficiency of products is improved, and the production cost is reduced.
