Description

Technical Field

[0001] This invention relates to the field of physics. More specifically, this invention relates to a fire-starting device for large-scale events. Background Technology

[0002] Large events or important celebrations often use torch relays or bonfires for opening ceremonies or to enhance the celebratory atmosphere, all of which require obtaining a fire source first. To better reflect a solemn sense of ceremony, a unique fire-making method is usually employed. Using concentrated sunlight to ignite flammable materials is one such method.

[0003] If the weather is cloudy or the sunlight is insufficient, it is impossible to obtain a fire using sunlight. In fact, successfully obtaining a fire involves many fundamental factors and requires stringent conditions, such as weather, ignition materials, and a fire source; the absence of any one of these will lead to failure. Furthermore, if traditional ignition methods are used, improper operation can cause a fire or even result in injury or death. The focusing Fresnel lens, with its light-focusing properties, can provide a different fire-starting device for large events or important celebrations. Summary of the Invention

[0004] The purpose of this invention is to provide a device for obtaining ignition (hereinafter referred to as ignition) using the characteristics of a Fresnel lens for large-scale events or important celebrations, giving the audience a technological feel beyond the sense of ceremony. The principle is that the Fresnel lens focuses sufficiently strong light and heat emitted from a light source, causing flammable materials to heat up and generate ignition. The method involves placing a Fresnel lens and a light (heat) source together on their optical axis. An object made of flammable material is placed on the optical axis, opposite to the light (heat) source, positioned at the location of the image of the light (heat) source formed by the lens. One or more such sets can be used simultaneously (to enhance heat projection). Generally, when multiple sets are used, the image of the light (heat) source falls on the same flammable material (several ignition points can also be set as needed). To enhance the performance effect, this invention also includes a lifting mechanism.

[0005] The specific technical requirements of this invention include: Fresnel lenses can have square or circular lens surfaces, but are not limited to square or circular. The light (heat) source is located on one side of the Fresnel lens; Flammable material, which is located on the opposite side of the Fresnel lens surface from the light (heat) source, and is coaxial with the center of the light (heat) source and the Fresnel lens; A Fresnel lens and a light (heat) source form a set. One set or multiple sets can be used. The light (heat) can be focused on the same flammable material or on several flammable materials as needed.

[0006] Preferably, the fire-starting device is characterized in that the Fresnel lens has the characteristic of focusing light, which can focus the light and heat emitted by the light (heat) source on one side onto the flammable material.

[0007] Preferably, the fire-starting device is characterized in that the light (heat) source is a 200W-2000W incandescent lamp, an electric arc, or sunlight, but is not limited to these three light (heat) sources that can emit heat.

[0008] Preferably, the fire-starting device is characterized in that the flammable material can be fixed or suspended as the front end of the torch. The flammable material consists of heat-absorbing material, combustible material and combustion-supporting material. It can be made by using steel wool as heat-absorbing material, adding a small amount of combustion-supporting material red phosphorus (or a material similar to match heads) and a certain amount of fiber as combustible material, or by soaking the fiber in a flammable solution.

[0009] Preferably, the fire-starting device is characterized by having a windbreak plate, which is higher than the fixed flammable material and is a transparent cylindrical surface. The material can be glass or plastic. The windbreak plate can surround the fixed flammable material and serve to block the wind and increase the temperature around the flammable material.

[0010] Preferably, the fire-starting device is characterized by having a platform or support for placing the Fresnel lens, the light (heat) source, and the flammable material.

[0011] Preferably, the platform or support is characterized in that, when it is positioned above the height of a person, a lifting platform is installed below it, allowing a person standing on the lifting platform to raise the torch to a ignition position, thereby enhancing the performance effect.

[0012] Preferably, the steel wool is characterized in that it is soaked in starch paste and then burned to become a black steel wool, thereby improving the heat absorption effect.

[0013] The present invention has at least the following beneficial effects: 1) This invention is a novel fire-starting device that uses the Fresnel lens focusing principle, which will break away from traditional fire-starting methods and enhance people's curiosity about science and technology as well as the audience's viewing experience; 2) The fire-starting device of the present invention is not easily affected by weather and external factors, which improves the stability of fire-starting and has high safety performance, making it less likely to cause a fire; 3) By combining the lifting platform with the fire-starting device, fire can be started from different heights to meet the needs of most celebrations and events. If the lifting platform is large, performances can also be held on it.

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0019] In this technical solution, the Fresnel lens 1 has the characteristic of focusing light, which can focus the light and heat emitted by the light (heat) source on one side onto the flammable material 3, and can obtain the fire source in the simplest way.

[0020] In this technical solution, the light (heat) source 2 can be a 200W-2000W incandescent lamp, an electric arc, or sunlight, but is not limited to these three types of light (heat) sources that can emit heat.

[0021] In this technical solution, the flammable material 3 can be fixed or suspended as the front end of a torch. The flammable material 3 is composed of heat-absorbing material, combustible material and combustion-supporting material. It can be made by using steel wool as heat-absorbing material, adding a small amount of combustion-supporting material red phosphorus (or a material similar to match heads) and a certain amount of fiber as combustible material. Alternatively, the fiber can be soaked in a flammable solution.
