<P>PROBLEM TO BE SOLVED: To solve the problems that in an electronically controlled firework lamp assembly, a luminescence lamp for shooting-up, an explosion lamp and a flash lamp are built in colored tubes and therefore, these lamps are functionally deteriorated due to heat generation, and the manufacturing cost of the assembly is high because of its complicacy with the other disadvantages such as the easy intrusion of water from the end parts of the tubes, the impossibility of changing the color of a firework as desired, in particular the tendency of the flash lamp to fail easily and its troublesome maintenance such as repair and replacement. <P>SOLUTION: This firework assembly does not use an electric bulb, a tubular neon lamp, a molding tubular lamp and a stroboscopic electric bulb and the projectile, explosion/flash elements of the firework assembly are substituted by a red light emitting diode, a green light emitting diode and a blue light emitting diode. Further, the projection/shooting-up of the firework through a controller according to the principle of three primary colors, the adjustment/control of the explosion and flash elements, the shooting-up/projection of the firework from the ground, the aerial explosion and finally the combustion of the firework into a flash state, are sequentially disguised and represented with sound. <P>COPYRIGHT: (C)2004,JPO |
