Description

Luminous fireworks

Technical Field

The utility model relates to a fireworks display.

Background

In the prior art, a protocol flower is a celebration entertainment article applied in the daytime and is used in various festive occasions such as wedding celebration, birthday congratulation, opening ceremony, entertainment programs, artistic performance, sporting meetings, festival celebration and the like. The effect pieces are made of various shaped articles, such as: various sculptures (such as stars, hearts and the like) made of color paper fragments, paillettes, color rings, color flowers, color tapes, color discs, foams and the like. The effect pieces are scattered in the launching tube in bulk, a pressure gas tank is arranged at the tail end of the launching tube, the pressure gas tank is opened by adopting a manual or electric gas tank opening mechanism, and the compressed gas is sprayed to push the effect pieces to spray. The effect pieces sprayed into the air are dispersed and distributed and float down, so that the effect of enjoying by people is formed.

The existing protocol flower has the main disadvantage that the protocol flower is not suitable for being used at night. Because the effect element has no photochromic effect, the ornamental value is not available at night. In the prior art, there are attempts to solve this problem, such as "a luminous fuse" disclosed in the chinese utility model patent document with the publication number CN2455714Y, "a firework-like device" disclosed in the chinese utility model patent document with the publication number CN 205138331U, "an umbrella arrow" disclosed in the chinese utility model patent application document with the publication number CN1281743, and the like, which all achieve a luminous effect by adding a luminous chemical material (such as a fluorescent agent) to the effect member. But the light color is weak and is difficult to achieve the effect of enough lift-off for appreciation. The above-mentioned document "arrow" also discloses the following: the power supply, the switch and the light-emitting device can be added in the arrow body, so that the light-emitting device in the arrow body can be flashing at the moment when the umbrella cover is unfolded, the umbrella drop of the umbrella body and the switch of the arrow body can be connected through a switch wire, when the umbrella arrow falls down from the air, because the air resistance borne by the umbrella body is greater than that of the arrow body, the switch wire can generate an upward pulling force relative to the switch in the arrow body, and the switch is started, so that the light-emitting device on the arrow body can be flashing. Although the brightness of the electroluminescent light source meets the requirement, the existing device serving as an effect piece of a firework still has the following disadvantages: the light-emitting structure has larger volume and high requirement on power for emitting the light-emitting structure into the air, and the requirement far exceeds the emission capability of a protocol firework pressure gas tank; different from the existing effect piece, the density of the light-emitting structure body is higher, and the existing firework structure is difficult to realize the reliable emission driven by pressure gas; the working reliability needs to be improved; the manufacturing cost is high, and the use cost is high in a large amount, so that the common civil market is difficult to accept; the device is used together with slowly falling floaters such as a parachute and the like; it is difficult to satisfy the requirement of acting as an effect member of the firework.

In addition, the emission height of the effect piece of the existing firework display is basically not controllable, and the emission height is difficult to set according to effect design in preparation.
