Description

Technical Field

[0001] This invention relates to the field of flashlights, and in particular to a multifunctional high-power flashlight. Background Technology

[0002] Multi-functional high-powered flashlights are commonly used civilian lighting tools, currently primarily sold as gifts and in supermarkets. The market's core demands focus on features such as magnetic induction brightness adjustment, temperature control, portability, and environmental adaptability. However, the lamp heads and overall structure of existing high-powered flashlights are gradually revealing numerous functional and structural shortcomings, specifically: Switch control often uses mechanical buttons or rotary structures, which are prone to mechanical wear and poor contact after long-term use. In addition, the supporting waterproof structure design is complicated and the sealing effect is poor, which can easily lead to water ingress and damage to internal components due to seal failure. Brightness adjustment is mostly manual, and cannot be automatically adapted to the usage scenario and lamp head temperature. Prolonged high-brightness operation can easily lead to overheating and light decay of LED beads, which not only shortens the lifespan of the beads, but also easily causes safety hazards such as burns. While magnetic switches have been used in flashlights, they mostly only achieve simple on / off functions and cannot simultaneously provide stepless brightness adjustment and temperature-linked control. Their limited functionality fails to meet diverse usage needs. The internal components of the lamp head are stacked in an unreasonable manner, resulting in low space utilization, poor heat dissipation efficiency, and difficulty in assembly and maintenance. In addition, the overall structure lacks lightweight design, has a single carrying method, and is not portable.

[0003] To address the shortcomings of existing technologies, there is an urgent need to design a multi-functional high-intensity flashlight that integrates magnetic induction adjustment, temperature control sensing, dual waterproofing with silicone rings one and two, and axially compact stacking of all the attached structures, thus resolving the technical deficiencies of existing products. Summary of the Invention

[0004] To address the shortcomings of existing high-powered flashlights, such as easily worn mechanical switches, lack of magnetic control for stepless dimming, lack of temperature control protection, limited lighting modes, poor waterproofing, unreasonable structural layout, and low portability, this invention provides a multi-functional high-powered flashlight. It achieves non-contact stepless brightness adjustment and temperature-linked cooling control through a magnetic control adjustment ring. A dual waterproof structure using two silicone rings ensures an IP65 waterproof rating, while a lightweight design enhances portability. This invention comprehensively improves the flashlight's ease of operation, safety, environmental adaptability, and portability.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a multi-functional high-intensity flashlight, including a pressure ring, high-transparency glass, silicone ring one, reflector cup, centering pad, lamp board, lamp body, magnetic control adjustment ring, drive board, pressure plate, silicone ring two, magnetic valve fixing cover, and lamp head and tail cover. The various structures are coaxially stacked and assembled from front to back along the axial direction. It also integrates a magnetic control adjustment component, a temperature control module, and a power supply component. The magnetic control adjustment component is located between the lamp body, the magnetic control adjustment ring and the driver board. The temperature control module is integrated into the driver board. The first silicone ring and the second silicone ring form a double waterproof structure. The power supply component is a USB interface power supply structure.

[0006] Using the above technical solution, this product achieves non-contact stepless dimming through a magnetic control adjustment ring and a Hall sensor. The temperature control module detects and adjusts the brightness in real time to achieve overheat protection. Silicone ring one and silicone ring two form a double waterproof structure to ensure IP65 waterproof rating. All attached structures, such as the pressure ring, high-transparency glass, and reflector cup, are stacked and assembled in layers along the axis. It also features a lightweight and portable design and universal USB power supply, achieving a balance between ease of operation, safety of use, environmental adaptability, and portability. It can be widely used in civilian lighting scenarios such as gifts and supermarket sales.

[0007] In summary, the present invention has the following beneficial effects: 1. By cooperating with the permanent magnet in the magnetic control adjustment ring and the linear Hall sensor on the drive board, non-contact stepless dimming is achieved, resulting in smooth brightness without jumps and a smooth operating feel. The non-mechanical contact adjustment structure fundamentally avoids mechanical wear and poor contact problems. In addition, the Hall sensor uses industrial-grade components that are resistant to temperatures of -40℃ to 150℃, have strong anti-interference capabilities, and can be adapted to harsh operating environments such as high and low temperatures and humidity, which greatly improves the lifespan of the flashlight and the user's operating experience. 2. By using the temperature sensor on the driver board and the temperature linkage logic of the control module, automatic current reduction protection is achieved when the internal temperature of the lamp body is ≥55℃. This effectively prevents the LED beads on the lamp board from overheating and light decay due to prolonged high-brightness operation, extending the service life of the LED beads and internal circuits such as the driver board. At the same time, it avoids the risk of burns caused by overheating of the lamp body. The design automatically restores the original brightness after the temperature drops to a safe range, ensuring continuous lighting while achieving protection, thus balancing safety and practicality. 3. The double waterproof structure is composed of silicone ring one and silicone ring two, both made of aging-resistant silicone material. The tight seal is achieved by the threaded pressing / screwing of the pressure ring and magnetic valve fixing cover. The overall waterproof rating reaches IP65, which can effectively prevent rainwater and water vapor from seeping in from the front and rear connection parts, ensuring that the flashlight works stably in complex environments such as rain, humidity, and wading, and greatly improving environmental adaptability. 4. The pressure ring, high-transparency glass, silicone ring one, reflector cup, centering pad, lamp board, lamp body, magnetic control adjustment ring, drive board, pressure plate, silicone ring two, magnetic valve fixing cover, and lamp head tail cover are coaxially stacked and assembled sequentially from front to back. The gap between each structure is controlled within 0.05-0.1mm, which optimizes the internal space utilization of the lamp head, resulting in a stable structure and high heat conduction efficiency. The drive board integrates all core control and drive components such as Hall sensor and control module. It is fixed inside the lamp body by pressing with the pressure plate, making disassembly and assembly convenient and facilitating later maintenance, repair and upgrades, thus reducing production and maintenance costs.

Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0011] refer to Figure 1 and Figure 2 A multi-functional high-intensity flashlight includes a pressure ring 1, high-transparency glass 2, silicone ring one 3, reflector cup 4, centering pad 5, lamp board 6, lamp body 7, magnetic control adjustment ring 8, drive board 9, pressure plate 10, silicone ring two 11, magnetic valve fixing cover 12, and lamp head and tail cover 13. The various structures are coaxially stacked and assembled from front to back along the axial direction. It also integrates a magnetic control adjustment component, a temperature control module, and a power supply component. The various structures and components work together to achieve magnetic control dimming, automatic cooling, waterproof sealing, compact assembly, and portable power supply functions. The magnetic control adjustment component is located between the lamp body 7, the magnetic control adjustment ring 8 and the driver board 9. The temperature control module is integrated into the driver board 9. The silicone ring 1 3 and silicone ring 2 11 form a double waterproof structure. The power supply component is a USB interface power supply structure, which supports power supply from mobile phones, power banks and computer USB ports.

[0012] refer to Figure 2 The pressure ring 1 is a ring structure, screwed onto the outer side of the front end of the lamp body 7. The high-transparency glass 2 is attached to the front end face of the lamp body 7. The silicone ring 3 is sandwiched between the high-transparency glass 2 and the front end face of the lamp body 7. The pressure ring 1 tightly fixes the high-transparency glass 2 and the silicone ring 3 to the front end of the lamp body 7 by screwing them together, so that the silicone ring 3 forms a sealed and attached state.

[0013] refer to Figure 2 The reflector cup 4 has a horn-shaped structure and is located inside the front end of the lamp body 7. The large end of the reflector cup 4 is attached to the inner side of the high-transparency glass 2, and the small end faces the centering pad 5. The centering pad 5 is sandwiched between the small end of the reflector cup 4 and the lamp plate 6. The lamp plate 6 is fixed inside the lamp body 7 and located behind the centering pad 5. LED beads are integrated on the lamp plate 6, and the LED beads are precisely aligned with the small end of the reflector cup 4.

[0014] refer to Figure 2 The magnetic control adjustment ring 8 is a ring structure and is embedded in the middle of the outer side of the lamp body 7. The magnetic control adjustment ring 8 can rotate around the lamp body 7. A gap of 0.05-0.1mm is reserved between the magnetic control adjustment ring 8 and the lamp body 7. The magnetic control adjustment ring 7 has a built-in permanent magnet 14. The magnetic field strength of the permanent magnet 14 changes linearly with the rotation angle of the magnetic control adjustment ring 7.

[0015] refer to Figure 1 and Figure 2 The drive board 9 is located inside the rear side of the lamp body 7. The pressure plate 10 is pressed onto the rear side of the drive board 9. The pressure plate 10 cooperates with the internal structure of the lamp body 7 to fix the drive board 9 inside the lamp body 7. The drive board 9 integrates a Hall sensor, a control module, a drive module, and a temperature sensor. The Hall sensor is a linear Hall element, which is positioned opposite to the permanent magnet 14 in the magnetic control adjustment ring 8. The distance between the two is controlled at 1-3mm. The Hall sensor is an industrial-grade element with a temperature resistance range of -40℃ to 150℃. It is used to detect the change in the magnetic field strength of the permanent magnet 14 in real time and convert it into an electrical signal to be transmitted to the control module.

[0016] refer to Figure 2 The control module integrates an MCU chip, with built-in brightness adjustment algorithm and temperature threshold judgment logic. It receives the magnetic field signal from the Hall sensor and the temperature signal from the temperature sensor and outputs control commands to the drive module. The drive module uses a PWM dimming chip, which receives commands from the control module to adjust the drive current of the LED beads on the lamp board 6. The drive module has overcurrent and overvoltage protection functions.

[0017] refer to Figure 2 The temperature control module includes a temperature sensor on the driver board 9 and a temperature linkage logic of the control module. The temperature sensor detects the internal temperature of the lamp body 7 in real time. When the detected temperature is ≥55℃, the control module automatically reduces the driving current of the LED beads. When the temperature drops to a safe range, the control module automatically restores the driving current to the level corresponding to the original brightness, thus achieving dynamic cooling protection.

[0018] refer to Figure 1 and Figure 2The silicone ring 11 is sandwiched between the rear end face of the lamp body 7 and the front end face of the magnetic valve fixing cover 12. The magnetic valve fixing cover 12 is a cylindrical structure with an internal thread on its inner side. The magnetic valve fixing cover 12 is screwed into the external thread on the outer side of the rear end of the lamp body 7 through the internal thread. After screwing, the silicone ring 11 forms a sealed fit. The lamp head tail cover 13 is set on the rear side of the magnetic valve fixing cover 12. The lamp head tail cover 13 is screwed into the external thread of the magnetic valve fixing cover 12 to realize the fixed assembly of the lamp head tail cover 13 and the magnetic valve fixing cover 12.

[0019] Brief description of usage: When dimming is required, the user rotates the magnetic control adjustment ring 8 on the outside of the lamp body 7. The permanent magnet 14 inside the magnetic control adjustment ring 8 generates a linear change in magnetic field strength with the rotation angle. The Hall sensor on the drive board 9 detects this change in magnetic field strength in real time and converts it into an electrical signal, which is transmitted to the control module. The control module outputs a PWM control command corresponding to the magnetic field strength to the drive module according to the built-in brightness adjustment algorithm. The drive module adjusts the drive current of the LED beads on the lamp board 6 according to the command to achieve stepless dimming. Specifically, when the magnetic control adjustment ring 8 is rotated clockwise, the magnetic field strength of the permanent magnet 14 increases, the drive current increases synchronously, and the brightness of the LED beads gradually increases. When the magnetic control adjustment ring 8 is rotated counterclockwise, the magnetic field strength of the permanent magnet 14 decreases, the drive current decreases synchronously, and the brightness of the LED beads gradually decreases. The entire process is non-contact adjustment with no mechanical wear. The heat generated by the LED beads on the light board 6 is conducted sequentially through the central pad 5 and the light board 6 to the light body 7, and then dissipated from the light body 7 to the flashlight shell for natural heat dissipation. The temperature sensor on the driver board 9 detects the internal temperature of the light body 7 in real time and transmits the temperature signal to the control module in real time. When the internal temperature of the light body 7 is detected to be ≥55℃, the control module triggers the temperature protection logic to reduce the heat generated by the LED beads and avoid overheating and light decay. When the internal temperature of the light body 7 drops to a safe range through heat dissipation, the control module automatically restores the drive current to the original brightness level, thus achieving cooling protection while ensuring continuous and stable lighting of the flashlight. This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
