Abstract

The invention discloses a laser fireworks igniter comprising a laser signal emitting unit (1) and a laser signal receiving unit (2), wherein the laser signal receiving unit (2) comprises an optical signal receiver (21), a receiver power supply (23) and an output control unit (22) for driving an igniting head (4) by an output end (223) of the output control unit (22) to ignite fireworks; the optical signal receiver (21) and the receiver power supply (23) are connected in series to form a trigger loop, the output control unit (22) is connected to the trigger loop and an input end of the output control unit (22) is connected between the optical signal receiver (21) and the receiver power supply (23). The laser fireworks igniter has the advantages of high safety reliability, strong anti-interference ability, simple structure and convenience in use.

Description

technical field [0001] The invention relates to a long-distance fireworks ignition device, in particular to a safe and reliable laser fireworks igniter which adopts laser signal remote control, can overcome the influence of external electromagnetic radiation signals. Background technique [0002] The conventional ignition method when setting off fireworks is artificial ignition at close range, but this ignition method is very dangerous. In order to enable people to light fireworks at a safe distance, electronic remote control mode is generally used to ignite at present. However, due to the complexity of the electronic frequency in the surrounding environment, when fireworks with wireless electronic remote control ignition are set off, they will suddenly detonate in case they are interfered by mobile phones, radio stations, etc., so electronic remote control ignition has potential safety hazards, thus limiting the use of fireworks . For example, during the Spring Festival o...
