[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example

[0018] See also Figure 1-Figure 3 As shown in the figure, a device for ignition based on the principle of light refraction is actually a device shaped like a flashlight, including a shell 1, a light source 9 and a power supply part for powering the light source. The shell 1 is further divided into a main shell 11 and a head shell 12. The head shell 12 is fixedly connected to the main shell 11 by threaded connection or other fixed means. The light source 9 and the power supply part are arranged in the main shell 11, and a focusing component is provided in the head shell 12. The focusing component includes a plurality of focusing convex lenses, two of which are in this embodiment, one is a first focusing convex lens 4, and the other is a second focusing convex lens 6. An optical cemented lens 2 is provided in the head shell on the side of the focusing convex lens away from the light source.

[0019] In this embodiment, the first focusing convex lens 4 and the second focusing convex lens 6 are superimposed and arranged. The first focusing convex lens 4 and the second focusing convex lens 6 are both plano-convex lenses, wherein the convex surfaces of the two focusing convex lenses are arranged toward the light source side.

[0020] In order to ensure that there is no shaking between the two focusing convex lenses, in this embodiment, a pressing ring 5 is provided between the two focusing convex lenses, and two ends of the pressing ring 5 respectively abut against the two focusing convex lenses.

[0021] To further ensure that the two focusing convex lenses do not wobble and provide a more stable connection, this embodiment provides an outwardly extending flange around the periphery of the focusing convex lenses. The flange has a uniform thickness inside and outside to form a fixing portion, and the ends of the pressure ring respectively contact the fixing portions of the two focusing convex lenses. The outer surface of the optical composite lens 2 is a convex surface, which abuts against the outer shell. A sealing ring 3 is provided between the optical composite lens and the inner wall of the outer shell. In this embodiment, the head shell 12 is arranged from front to back. From front to back, the head shell 12 is provided with a first positioning step for positioning the optical composite lens 2, a second positioning step for positioning the sealing ring 3, and a third positioning step for positioning the focusing convex lens. A pressure ring 7 is provided within the head shell 12, which is threadedly connected to the head shell 12, and the end of the pressure ring 7 abuts the focusing convex lens. The arrangement of the positioning steps allows the optical composite lens 2, the sealing ring 3, the first focusing convex lens 4, and the second focusing convex lens 6 to be compressed and fixed, and only a single pressure ring is required to achieve compression of the various components.

[0022] The inner wall of the clamping ring is provided with a tool retaining portion for driving the clamping ring to rotate, so as to facilitate tightening the clamping ring.

[0023] The working principle of this embodiment is that the scattered light is emitted by the lamp bead, and the scattered light is gathered by the first focusing convex lens, and then gathered again by the second focusing convex lens, so that the scattered light is focused into a small range of light beams, and finally focused into a very small point light by the optical cemented lens, so that the light intensity is stronger, the brightness is brightest, and the heat is most concentrated, thereby achieving the purpose of igniting the object.
