Description
Technical field
The utility model relates to the technical field of simulation pyrotechnics, particularly a kind of aerial LED fireworks automatically opened.
Background technology
Little fireworks display in traditional fireworks, or the combined firework be made up of little fireworks display, be transmitted into effect part in the air through fireworks tube, form light and color, view and admire for people by the combustion reaction of pyrotechnic composition.
LED can send red, green, yellow, blue, etc. the light of different color, being widely used in dressing up of red-letter day, having that the life-span is long, light efficiency is high, the radiationless advantage with low-power consumption, but be generally hang, be fixed on building or shelf, is not dynamically float aloft.LED is combined with traditional fireworks, the needs that people observe the day can be met, the requirement of economy, environmental protection can be met again.
But, bring so again another problem: if LED be first energized, load in fireworks tube, then be transmitted into aerial, because generally can only several hours be maintained for the battery of LED luminescence, city's pin product can not be formed.Also can by LED switch connection before being about to set off, reinstall after lamp is bright in fireworks tube and be emitted to aerial, but in-site installation is very inconvenient.Therefore, need to propose a kind of aerial LED fireworks automatically opened.
Summary of the invention
The purpose of this utility model is to provide a kind of aerial LED fireworks automatically opened, traditional fireworks technology is merged dexterously with modern LED art, effect part LED in little for tradition fireworks display is substituted, newly-increased a kind of amusing products viewed and admired for people.
The purpose of this utility model is realized by following technical proposals: a kind of aerial LED fireworks automatically opened, comprise fireworks tube, described fireworks tube bottom arranges the first gunpowder layer and ignition fuse, effect inner core is equipped with on the top of described fireworks tube, be provided with the first lid between described first gunpowder layer and described effect inner core to cling to, described first lid bar was provided with fire hole, was provided with ignition powder bottom described effect inner core, describedly crossed that fire hole is corresponding with described ignition powder arranges; The inside of described effect inner core is equipped with the second gunpowder layer, the second lid bar, refuge floor, LED matrix successively, described second gunpowder layer is connected with described ignition powder by leading fire lead-in wire, described effect inner core is fixed with insulating trip, and one end of described insulating trip is inserted in the closed circuit of described LED matrix.
The utility model compared with prior art tool has the following advantages:
1, traditional fireworks technology merges with modern LED art by the utility model dexterously, and can realize colourful dynamic change effect, current pyrotechnic composition is also difficult to reach.
2, the utility model utilizes pyrotechnic composition to launch LED matrix, and completes the power-on servicing of LED, realizes the automatic unlatching of LED.
3, LED fireworks are compared with the little fireworks display of conventional smoke gunpowder, safer, more environmental protection.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Detailed description of the invention
Embodiment one:
See Fig. 1 to Fig. 3, a kind of aerial LED fireworks automatically opened, comprise fireworks tube 1, described fireworks tube bottom arranges the first gunpowder layer 4 and ignition fuse 3, effect inner core 6 is equipped with on the top of described fireworks tube, is provided with the first lid and clings to 5 between described first gunpowder layer and described effect inner core, and described first lid bar was provided with fire hole 7, be provided with ignition powder 8 bottom described effect inner core, describedly cross that fire hole is corresponding with described ignition powder arranges; The inside of described effect inner core is equipped with the second gunpowder layer 9, second lid bar 10, refuge floor 11, LED matrix 12 successively, described second gunpowder layer is connected with described ignition powder by leading fire lead-in wire 13, described effect inner core is fixed with insulating trip 14, and one end of described insulating trip is inserted in the closed circuit of described LED matrix.
In the present embodiment, described fireworks tube adopts traditional structure, arranges mud head 2 bottom fireworks tube, and mud head, for keeping the center of gravity of fireworks tube, prevents fireworks tube from tilting.The top of fireworks tube arranges outer package layer 15, and effect inner core loads after in fireworks tube and completes encapsulation, prevents fireworks from making moist or content is deviate from.
In the present embodiment, described first lid bar 5, second lid bar 10 is scraps of paper, and the first lid bar 5 is combined closely with described fireworks tube 1 inwall, prevents the first gunpowder layer 4 from loosening.Second lid bar 10 is combined closely with described effect inner core 6 inwall, prevents the second gunpowder layer 9 from loosening.The material of described first gunpowder layer, described second gunpowder layer is military project nitre.
In the present embodiment, described LED matrix 12 can be the LED with flicker effect, and are all commercially available prod, the internal structure of LED matrix belongs to prior art, is not described in detail herein.
