Abstract
A fuse-less ignition system for fireworks. An ignitor module is provided that is insertable into a firework and includes: a first end having an interface adapted to reside on an exterior surface of the firework for receiving a plug; a set of electrical contacts adapted to receive electricity from the plug; a heat element coupled to the electrical contacts and adapted to heat in response to received electricity; and a cavity adjacent to the heat element containing a pyrotechnic material, the pyrotechnic material adapted to ignite in response to a heating of the heat element.

An ignitor module insertable into a firework, comprising:
- a first end having an interface configured for exposure on an exterior surface of the firework, the interface configured for receiving a plug;
- a set of electrical contacts adapted to receive electrical current from the plug;
- a heating element coupled to the electrical contacts and adapted to convert electrical energy to heat energy in response to receiving electrical current;
- and
- a second end having an ignition element adjacent to the heating element that includes an open cone-shaped cavity with a first opening located proximate the heating element at a first end and a second opening at an opposed end, wherein the open cone-shaped cavity is filled with a pyrotechnic material, the pyrotechnic material adapted to ignite in response to heat energy generated by the heating element.
A firework, comprising:
- an ignitor module insertable into a firework, having:
- a first end having an interface configured for exposure on an exterior surface of the firework, the interface configured for receiving a plug;
- a set of electrical contacts adapted to receive electrical current from the plug;
- a heating element coupled to the electrical contacts and adapted to convert electrical energy into heat energy in response to receiving electrical current;
- and
- a second end having an ignition element located adjacent to the heating element that includes an open cavity with a first opening located proximate the heating element at a first end and a second opening at an opposed end, wherein the open cavity is filled with a pyrotechnic material, the pyrotechnic material adapted to ignite in response to heat energy generated by the heating element to ignite an initial effect of the firework via the second opening.
An ignitor module insertable into a firework, comprising:
- a first end having an interface configured for exposure on an exterior surface of the firework, the interface configured for receiving a plug;
- a set of electrical contacts adapted to receive electrical current from the plug;
- a second end having an open cavity exposed to a tungsten coil, wherein the tungsten coil is coupled across the electrical contacts, and wherein the tungsten coil extends outwardly from the electrical contacts and is adapted to generate heat in response to receiving electrical current;
- and
- wherein the tungsten coil is configured to directly ignite pyrotechnic material in the open cavity.
