Novel firework with LED display and music play

Abstract

The invention relates to a novel firework with LED display and music play. The novel firework comprises a high-altitude set-off firework, an on-site LED caption firework, and an automatic sensing electrifying device that is connected with the high-altitude set-off firework and the on-site LED caption firework through circuits; the automatic sensing electrifying device comprises a control chip, a temperature control switch, a power supply, an LED caption display screen and a sound box, wherein the temperature control switch, the power supply, the LED caption display screen and the sound box are connected with the control chip; the temperature control switch is connected with a firing line on the high-altitude set-off firework; the temperature control switch is used to connect the power supply according to the sensed temperature of the firing line and synchronously control the LED caption display screen to light as well as control the sound box to produce music. According to the novel firework with the LED display and music play, the temperature control device controls the connection or disconnection of a circuit control power supply, thus the safety in firework control is ensured; the LED caption firework does not produce any smoke, is long in lighting time, low in temperature, safe and recyclable.

Description

technical field [0001] The invention relates to the field of fireworks, in particular to a novel fireworks with LED display and music playing. Background technique [0002] The shapes displayed in the air of the existing potted flowers and fireworks shell products are formed by combining the shell body with sound, light and color after it is lifted into the air and detonated, but the shape formed by the shell body is simply superimposed and matched. [0003] With the continuous development of firework technology, and people are more or less bored with the traditional way of fireworks, and later appeared subtitle fireworks with shelves, which are made by the displayer to put multiple single independent fireworks Fireworks are put together to form a subtitle pattern, and then all the single fireworks in the subtitle system are systematically lit at the same time to display the subtitle pattern.

Problems solved by technology

[0003] With the continuous development of firework technology, and people are more or less bored with the traditional way of fireworks, and later appeared subtitle fireworks with shelves, which are made by the displayer to put multiple single independent fireworks Fireworks are put together to form a subtitle pattern, and then all the single fireworks in the subtitle system are systematically lit at the same time to display the subtitle pattern. This kind of fireworks is set off on the spot, which is very expensive to produce and is not easy to promote. Specialized technicians carry out debugging and supervision work, and there are many steps, and this kind of fireworks will produce a lot of smoke like traditional gunpowder fireworks, and the bright time is also short, and it is easy to catch fire when the temperature is high at the festival site
