No-power outdoor warning light

Abstract

We provide a non-battery type outdoor warning light. [Solution] The light has an outer shell 1, a fixed support 2 inside the shell, and an induction coil 3 and two strip lights 4 wound around the outer circumference of the support. The induction coil is located in the center of the two strip lights and is electrically connected. A slidable magnet A5 is installed inside the support, and fixed magnets B 6 are installed at both ends of the support. Magnet A is subjected to repulsive forces by magnets B at both ends. The strip lights are LED strip lights. The outer shell is cylindrical, with a transparent cylindrical surface. The support is a cylindrical pipe. This non-powered outdoor warning light has an ingenious and simple design, and generates power using natural kinetic energy, so it does not require batteries or charging, saves power, and has a long life, making it extremely practical and popular.

Description

[Technical Field]

[0001] The present invention relates to the technical field of outdoor warning lights, and more particularly to outdoor warning lights. [Background technology]

[0002] To avoid nighttime collisions, it is recommended that people, animals, bicycles, and other vehicles outdoors at night be equipped with warning lights that can be seen from a long distance. Currently, there are various types of nighttime warning lights available on the market, including those using fluorescent materials, those using reflective materials, and battery-powered lights. However, fluorescent and reflective materials do not provide sufficient luminous efficacy, and battery-powered lights require battery replacement or charging, resulting in short service life and cumbersome handling. For this reason, there is currently a shortage of outdoor warning lights that do not require battery replacement or charging. Summary of the Invention

[0003] SUMMARY OF THE INVENTION The problem to be solved by the present invention is to overcome the drawbacks of the above-mentioned technology and provide a non-powered outdoor warning light.

[0004] To solve the above problems, the present invention provides a battery-free outdoor warning light that includes an outer shell, a fixed support pole inside the shell, a coil and two light strips wound around the outer periphery of the support pole, the coil being positioned in the center of the two light strips and electrically connected to them, a slidable magnet A inside the support pole, and fixed magnets B at both ends of the support pole. Preferably, the magnet A is subjected to a repulsive force by the magnets B on both ends. Preferably, the strip light is an LED strip light. Preferably, the shell is cylindrical and the cylindrical surface is transparent. Preferably, the support is a cylindrical pipe.

[0005] Compared with the prior art, the advantages of this invention are as follows: This warning light can be attached to people, animals, or vehicles active outdoors, and can be securely attached by methods such as fitting, banding, or adhesive. During use, magnet A moves back and forth within the support pole, and is pushed back by the repulsive forces of magnets B on both ends to avoid collisions. The movement of magnet A crosses the sensitive coil, generating electricity through electromagnetic induction, which then supplies power to the strip light. This non-powered outdoor warning light generates electricity using natural kinetic energy, so it does not require batteries or charging, saving power and having a long lifespan. [Brief explanation of the drawings]

[0006] [Figure 1] 1 is a cross-sectional view of a non-powered outdoor warning light according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0007] The non-powered outdoor warning light of the present invention will be described in more detail below with reference to the accompanying drawings. As shown in Figure 1, the battery-free outdoor warning light has an outer shell 1, a fixed support pole 2 inside the outer shell 1, and an induction coil 3 and two strip lights 4 wound around the outer periphery of the support pole 2. The induction coil 3 is located in the center of the two strip lights 4 and is electrically connected to them. A slidable magnet A5 is located inside the support pole 2, and fixed magnets B6 are located on both ends of the support pole. The magnet A5 receives a repulsive force from the magnets B6 on both ends. The tape light 4 is an LED tape light. The outer shell 1 is cylindrical and the cylindrical surface is transparent. The support 2 is a cylindrical pipe.

[0008] In practical application, this device can be attached as a warning light to people, animals, bicycles, etc. active outdoors, and can be attached by means of fitting, banding, adhesive, etc. During use, magnet A5 moves back and forth within support 2, and is pushed back by magnets B6 at both ends by repulsive forces to avoid collisions. As magnet A5 moves, it crosses the sensitive coil, generating electricity through electromagnetic induction, which is used as a power source for strip light 4.

[0009] The above description describes the present invention and its embodiments, but the scope of protection is not limited thereto. The drawings are merely an embodiment of the present invention, and actual applications are not limited thereto. In other words, any structural aspects and embodiments similar to the technical means designed by a person skilled in the art based on the suggestions, without departing from the creative spirit of the present invention, should all fall within the scope of protection of the present invention.
