One is explosion lamp 5 and the other is flashing lamp 6 and they are b arranged in regular order. These bulbs or tubular lamps can be arranged to have various special configurations and be provided on different spherical layers. These spheres take the supporting ball as their center. The number of the layers of the explosion lamps 5 should be no less than three. The more the layers are and the shorter the distance between the layers is, the better the continuity of explosion of these lamps is and the more effective the simulation of the conventional fireworks is. The lamps in the same sphere (layer) are connected together, so that lamps in different layers are lit up successively outward from the ball center. The flashing lamps 6 are on the outer ends of the radiation levers 3 and are consisted of a plurality of small bulbs and stroboscopic bulbs.
