ABSTRACT:
This application claims the benefit under 35 U.S.C. §119 of Chinese application number 99118779.2 filed on Jun. 9, 1999 and Chinese application number 98239009.2 filed on Jul. 10, 1998. The present invention relates to a lamp assembly. In particular the present invention relates to a lamp assembly which can simulate the explosion process of fireworks and the manufacturing method thereof.
BACKGROUND OF THE INVENTION
Conventional fireworks are a cardboard cylinder filled with powder and oxidizer, which flies up to the air and produces flames of various colors after being fired, making festival atmosphere more warm. However, it has several drawbacks, including high production cost, causing environment pollution, possibility of injuring people and even causing fire disaster and the possibility of exploding and burning during its production and transport. Therefore, setting off fireworks is prohibited in many cities, and so the festival warm atmosphere is reduced dramatically.
It is desired that there is a product, which can produce the same effect as conventional fireworks but does not have the above drawbacks.
SUMMARY OF THE INVENTION
The object of the present invention is achieved by an electronic-controlled fireworks lamp assembly, including an emitting framework, a supporting ball, radiating levers and a controller. The emitting framework is connected to radiating levers via supporting ball, the radiating levers are bent into a shape as to produce the effect of fireworks explosion. The explosion lamp and flashing lamp are attached to the radiating levers. The controller is connected with firing lamps, explosion lamps and flashing lamps. Alternatively, the radiating levers can be straight levers to which explosion lamp and firing lamp attach. The emitting framework is consisted of metal tubes or metal supports to which firing lamps attach. The supporting ball is a metal support of spherical shape having a plurality of installing bores therein. Explosion lamps are arranged on at least three spherical layers radially outward from the center of the supporting ball by inserting them into the bores of the supporting ball directly.

The explosion lamp and flashing lamp are attached to the radiating levers. The controller is connected with firing lamps, explosion lamps and flashing lamps. Alternatively, the radiating levers can be straight levers to which explosion lamp and flashing lamp attach. The emitting framework is consisted of metal tubes or metal supports to which firing lamps attach. The supporting ball is a metal support of spherical shape having a plurality of installing bores therein. Explosion lamps are arranged on at least three spherical layers radically outward from the center of the ball. The radiating levers are connected to the supporting ball by inserting them into the bores of the supporting ball directly.
The manufacturing method of the electronic-controlled fireworks lamp assembly is as follows: Firing lamp is composed of colored tubes made of rigid plastics with high strength; the interior of the tubes is provided with rows of light-emitting bodies and lead the extension line out; the ends of the tubes are sealed tightly with adhesive; these tubes can constitute emitting framework itself, or can be used in combination with radiating levers, The emitting framework can be designed into the shape of the block, lever or artistic model, it can flash upward or do not flash; and the framework can be colored lamp or colored cylinder in which electrical wires and controller are provided; the supporting ball is an explosion center in which bores are provided for radiating levers passing through; the supporting ball can be provided at a plurality of locations on the emitting framework or radiating levers, producing many explosion centers, and the controller in the emitting framework can control these centers and make them explode and radiate successively. The shape of radiating levers can be curved, straight and overlapping and the levers have different length that can be combined into many geometry such as spherical shape and fan shape. The cross-section of the radiating levers can be circular, flat or special shaped. Explosion points explode outward successively taking the supporting ball as explosion center and supporting balls can be arranged on upper, middle and lower part of the lamp assembly as well as on radiating levers and be used for the second and third radiation. The firing lamp is made of rigid polycarbonate, the inner surface of which is provided with refractive stripes. The explosion order of the lamp assembly is that the firing lamps on the emitting framework are lit up from lower to upper as far as reaching the center of the supporting ball and then radiation lamps are lit up outward from the center of supporting ball and after that the flashing lamps flash. Explosions operate in layers during the whole process and flashing lamps flash finally, thus an explosion cycle is completed.
The present invention basically replaces conventional fireworks of powder type by specially manufactured fireworks lamp assembly which simulates the explosion process of conventional fireworks using electronics-control system. The present invention is easy to use and operate safely, which can replace conventional fireworks very effectively and can be used in the cities and countryside for decoration in cases of festivals and important celebration activities.
