Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and more specifically, to a lighting fixture with a rotatable and switchable light source. Background Technology

[0002] Flashlights, as a common lighting device, are widely used in various scenarios such as daily life, outdoor camping, nighttime exploration, and professional repair. Traditional flashlights typically have a cylindrical design, with their structure mainly consisting of a grip to house the power source and related components, and a head to house the light source and lens. However, traditional flashlights have a limited range of light output modes, are greatly affected by the usage environment, and struggle to meet diverse usage needs. With the expansion of their applications, people are placing higher demands on the functionality of flashlights, such as the increasing need to adjust the light output performance according to different scenarios.

[0003] Most existing flashlights achieve high / low beam switching by adjusting the distance between the module and the reflector or lens. Common methods include pulling or rotating the flashlight head to change the distance between the module and the outermost lampshade, thereby adjusting the beam's focus. While this method can achieve floodlight and focused beam switching to some extent, it often requires the user to use both hands, making it inconvenient. Furthermore, because the flashlight head is designed to be pullable or rotatable, a certain gap inevitably exists at the connection between the head and the outer shell. The size of this gap is not easily controlled manually; with prolonged use, the gap at the connection between the flashlight head and the outer shell gradually widens, resulting in less than ideal waterproof performance.

[0004] Furthermore, traditional flashlights typically require adjusting the relative position between the light source and the lens when switching light effects. This not only increases the complexity of the device but also limits the overall compactness of the structure. Frequent mechanical adjustments can lead to wear and tear on the connecting components between the light source and the lens, further affecting the reliability and lifespan of the device. Utility Model Content

[0005] The purpose of this application is to provide a lighting fixture with a rotatable and switchable light source, which has a simple and compact structure, is easy to operate, and has excellent waterproof performance.

[0006] This application provides a rotatable switching light source lighting fixture, the technical solution of which is as follows: A rotatable switching light source lighting fixture includes a grip, a rotating cylinder, and a lighting assembly connected to the grip; the lighting assembly includes a light source protection part, at least two lighting sources disposed on the light source protection part, and a switching module connected to the lighting sources; the rotating cylinder is rotatably connected to the outside of the light source protection part, and is provided with a light emitting part and a driving part connected to the switching module; the rotating cylinder is configured to drive the switching module to switch and control one of the lighting sources to work by rotating, and to switch the light emitting part to the position above the lighting source in the lighting state.

[0007] Furthermore, this application also proposes that there are three lighting sources: a floodlight source, a laser source, and a spotlight source, which are distributed around the central circumference of the light source protection unit.

[0008] Furthermore, this application also proposes that the focusing light source includes a focusing module connected to the control system and a focusing lens disposed on the light source protection part, and the floodlight light source includes a floodlight module connected to the control system and a floodlight lens disposed on the light source protection part. Along the length direction of the central axis of the light source protection part, the focusing module is lower than the floodlight module, and the focusing lens is smaller than the floodlight lens so that the focusing light source obtains a smaller beam angle and the floodlight light source obtains a larger illumination area.

[0009] Furthermore, this application also proposes that the laser source includes a laser module and a laser lens tilted on the light source protection part; the tilt angle of the laser lens is 4° to 15°.

[0010] Furthermore, this application also proposes that the shaft of the light source protection unit is provided with a through hole for the drive unit of the rotating drum to pass through and be inserted into the switching module, and the switching module is provided with a slot corresponding to the drive unit.

[0011] Furthermore, this application also proposes that a fixed middle section is provided between the grip and the rotating drum, and the two ends of the fixed middle section are suitable for connecting the grip and the light source protection part; and waterproof sealing rings are provided between the fixed middle section and the grip and the light source protection part.

[0012] Furthermore, this application also proposes that the outer wall of the light source protection part is uniformly provided with a number of slots around the circumference, and the inner wall of the rotating cylinder is provided with a number of protrusions suitable for matching the slots. The protrusions are suitable for engaging with the slots when the rotating cylinder is rotated into position to provide a damping force that limits the continued rotation of the rotating cylinder.

[0013] Furthermore, this application also proposes that an actuator is provided in the grip wall, the actuator being connected to a control system to enable or disable the lighting components based on the different actions performed by the user on the actuator.

[0014] Furthermore, this application also proposes that the grip portion is suitable for installing a power supply and control components, the power supply being a dry cell battery or a rechargeable battery; the outer surface of the grip portion is suitable for having a textured surface to enhance friction.

[0015] Furthermore, this application also proposes that the light-emitting part of the rotating drum is configured as a fan-shaped opening, a frustum-shaped opening, or a square opening for light output, and the driving part is configured as a plug suitable for matching with the switching module; and anti-slip texture is provided on the outer side of the rotating drum.

[0016] As can be seen from the above, the rotatable switching light source lighting fixture provided in this application directly controls the switching of different lighting sources through the rotation of the rotating drum. The light-emitting section on the rotating drum synchronously switches to the light source in working condition. Users can achieve flexible control of the light source with just one hand, making operation simple and convenient. Furthermore, the use of a fixed middle section and a waterproof sealing ring enhances structural stability and waterproofing, resulting in a simple and compact structure, convenient operation, and excellent waterproof performance.

[0025] In existing technologies, flashlights, as basic lighting fixtures, generally suffer from cumbersome light source switching operations and insufficient structural sealing. Traditional products achieve light effect switching by pulling or rotating the head to adjust the distance between the light source and the lens, requiring two-handed operation. Furthermore, prolonged use increases mechanical clearance, leading to a decrease in waterproof performance. For example, in outdoor camping scenarios, users need to frequently switch between floodlight and spotlight, where the inconvenience of traditional structures is particularly pronounced, and there is a risk of water leakage in rainy or foggy environments.

[0026] Analysis revealed that existing technologies are primarily limited by the separate control mechanisms for light source switching and optical path alignment. This embodiment integrates mechanical drive and circuit switching, simplifying operation; the use of a rotating component-linked switch module enables one-handed control; and the nested structure of the fixed light source protection unit 4 and the light-emitting unit 22 of the rotating drum 2 reduces the dynamic sealing surface. This leads to a design concept that simultaneously completes light source activation and optical path alignment through a single rotational motion.

[0027] Combination Figures 1 to 7 As shown, specifically, this embodiment proposes a rotatable switching light source lighting fixture, including a gripping part 1, a rotating cylinder 2, and a lighting component 3 disposed on the gripping part 1. The lighting component 3 includes a light source protection part 4, at least two lighting sources, and a control component 5 with a switching module 51. The rotating cylinder 2 is rotatably sleeved on the outside of the light source protection part 4, and has a light-emitting part 22 and a driving part 23 connected to the switching module 51. Rotating the rotating cylinder 2 can trigger the switching module to switch the lighting source and move the light-emitting part 22 above the corresponding light source. It should be noted that the lighting sources mentioned here can be set to 2, 3, 4, or more, and can be floodlights 31, lasers 32, and spotlights 34, etc., including but not limited to these, for example, they can also be multi-color lighting sources.

[0028] The light source protection unit 4 refers to the rigid housing for fixing and mounting the lighting source. It can be made of extruded aluminum alloy and its function is to provide a stable mounting platform for multiple light sources, prevent light source misalignment from affecting the accuracy of the optical path, and provide heat dissipation. The control component 5 refers to an electronic unit integrating a circuit control module, which may include a PCB board and a miniature relay, used to control the on / off state of different light sources. The switching module 51 refers to a multi-channel electronic switch that can be mechanically triggered, such as a rotary encoder or a contact slider switch, and its function is to convert the physical rotation of the rotating drum 2 into an electrical signal for switching. The drive unit 23 refers to the mechanical component that transmits the rotational motion of the rotating drum 2 to the switch module, such as a plug rod, for precisely triggering the switch contacts. The light output unit 22 refers to the light output window opened on the rotating drum 2, the position and shape of which are designed to match the light emission direction of the lighting source.

[0029] The light source protection unit 4 is fixed to the front end of the grip unit 1, and multiple ring-shaped lighting sources are connected to the independent circuits of the control component 5. The rotating cylinder 2 is fitted around the outer circumference of the light source protection unit 4, and its inner drive unit 23 extends and inserts into the slot 52 of the switching module 51. When the user rotates the rotating cylinder 2, the drive unit 23 drives the contacts in the switching module to switch on / off states, energizing the corresponding lighting source. Simultaneously, the light-emitting part 22 of the rotating cylinder 2 rotates synchronously to directly above the light source, forming a complete light path output. The entire process requires no adjustment of the lens position; light source switching and light path alignment can be completed simply by the unidirectional rotation of the rotating cylinder 2.

[0030] Compared to existing technologies, traditional solutions rely on head extension and retraction to change the light effect, requiring two-handed operation and presenting dynamic sealing challenges. This solution, through the cooperation of a fixed light source and a rotating light-emitting section 22, eliminates the sealing surface issues associated with movable light source modules. The static sealing structure of the rotating cylinder 2 and the light source protection section 4 facilitates waterproof design. A rotation-triggered switch module replaces the traditional push-pull mechanical switch, reducing wear on moving parts and improving operational reliability. Therefore, through the above technical solutions, this application enables single-handed rotational operation to switch light sources, simplifying operation and improving ease of use. The fixed light source layout and overall sealing structure enhance waterproof performance, making it suitable for humid environments. The direct connection design of the rotation drive and circuit switching reduces mechanical transmission losses and extends the equipment's lifespan. The synchronous alignment mechanism between the light-emitting section 22 and the lighting source ensures stable light spot shape, avoiding light scattering problems caused by mechanical gaps in traditional solutions.

[0031] Combination Figures 4 to 6As shown, in a preferred embodiment, three lighting sources can be provided: a floodlight source 31, a laser source 32, and a focused light source 34. These three lighting sources are distributed circumferentially around the axis of the light source protection unit 4. The floodlight source 31 is a light source capable of providing uniform illumination over a wide area. Specifically, it can be implemented using an LED module with a large-area floodlight lens, and its beam angle is greater than that of the focused light source 34 to cover a wider area. The laser source 32 is a linear light source with directional projection capability. Specifically, it can be implemented using a semiconductor laser with a tilted laser lens 33, forming a visible light spot for positioning through beam collimation. The focused light source 34 is a light source with high-intensity long-range projection capability. Specifically, it can be implemented using a small-sized LED module with a small-diameter focused lens, and its beam angle is smaller than that of the floodlight source 31 to increase the illumination distance. The circumferential distribution means that the three light sources are arranged on the same plane with the axis of the light source protection unit 4 as the center. Specifically, they can be arranged with equal spacing of 120°. The rotation of the rotating cylinder 2 allows different light sources to be switched to align with the light-emitting part 22.

[0032] Specifically, three light sources are fixed to the light source protection unit 4 to form a stable structure. When the rotating drum 2 rotates, the drive unit 23 triggers the switching module 51 to select the corresponding light source for power supply. When the rotating drum 2 drives the light-emitting unit 22 to rotate above the floodlight source 31, the floodlight module is powered on to generate wide-angle illumination; when the rotating drum 2 rotates to the position of the laser source 32, the laser module is activated and projects a directional beam through the tilting lens; when the rotating drum 2 rotates to the position of the focusing light source 34, the focusing module is activated and forms a long-range light spot through a small-diameter lens. The light source fixing method avoids the operation of adjusting the distance between the lens and the light source in traditional technology. The rotating drum 2 only needs to rotate in one direction to complete the light effect switching. Through this solution, the rapid switching of three functions—floodlight illumination, long-distance focusing, and laser positioning—in a single device is realized. During operation, only the rotating drum 2 needs to be rotated to complete the light effect conversion. The light source fixing layout avoids the mechanical wear caused by frequent adjustments in traditional technology. The design of no axial displacement between the rotating drum 2 and the light source protection unit 4 ensures the sealing performance of the overall structure and solves the defects of easy water ingress and complex operation of multi-effect switching devices.

[0033] Specifically, in this embodiment, the focusing light source 34 includes a focusing module connected to the control system and a focusing lens disposed on the light source protection part 4. The floodlight source 31 includes a floodlight module connected to the control system and a floodlight lens disposed on the light source protection part 4. Along the length of the central axis of the light source protection part 4, the focusing module is lower than the floodlight module; and the focusing lens is smaller than the floodlight lens so that the focusing light source 34 obtains a smaller beam angle and the floodlight source 31 obtains a larger illumination area. The focusing module refers to a light-emitting unit integrated via a circuit board, specifically implemented using surface-mount LEDs or COB packages. Its mounting position is lower than the floodlight module to form a layered layout in the axial space. The floodlight module refers to a light-emitting unit with a wide-angle light emission, specifically implemented using an array of multiple LEDs or an integrated surface light source. Its mounting position is higher than the focusing module to utilize the upper space of the light source protection part 4. The focusing lens refers to an optical element with a small aperture, specifically implemented using an aspherical lens or a total internal reflection structure. Its size is smaller than the floodlight lens to constrain the beam divergence angle. A floodlight lens is a large-sized optical element, which can be implemented using Fresnel lenses or diffuser structures. Its coverage area is larger than that of a condenser lens to expand the illumination range.

[0034] Specifically, the focusing module is fixedly installed in the lower axial region of the light source protection unit 4 near the holding part 1, with a small-sized focusing lens positioned above it. The beam forms a concentrated spot after passing through the lens. The floodlight module is fixedly installed in the higher axial region of the light source protection unit 4 away from the holding part 1, with a large-sized floodlight lens covering the module's light-emitting surface. The light is refracted and diffused to form uniform illumination. The two light source modules are arranged in a stepped manner along the axis, avoiding optical path interference and eliminating the need for mechanical displacement adjustment. Light source selection is achieved by switching the control system circuit. This solution achieves light effect switching while maintaining a static structure by fixing different light source modules and corresponding lenses in a layered axial manner, eliminating the sealing risks caused by moving parts. The size difference between the focusing lens and the floodlight lens directly corresponds to the optical performance requirements, avoiding the optical performance loss caused by a single lens having to accommodate multiple light effects in traditional solutions. The layered axial layout optimizes space utilization, and the matching design of different sized lenses with corresponding light sources ensures the independence of optical performance.

[0035] Combination Figure 5As shown, in this embodiment, the laser source 32 includes a laser module and a laser lens 33 tilted on the light source protection unit 4. The tilt angle of the laser lens 33 is 4° to 15°. The laser module is the core light-emitting unit used to emit a laser beam, which can be implemented using a semiconductor laser or a solid-state laser. It directly generates a highly collimated laser beam to meet directional lighting requirements. The laser lens 33 is an optical element that collimates or focuses the laser beam. It can be implemented using a convex lens or an aspherical lens. The lens material can be glass or optical resin. The tilted installation adjusts the optical path direction to solve the problem of beam offset. Specifically, after the laser beam emitted by the laser module passes through the tilted laser lens 33, its optical path direction is precisely adjusted. The tilt angle is controlled within the range of 4° to 15°, which can directly compensate for optical path offset through fixed installation while avoiding an increase in lens installation space requirements due to excessive angle. This angle range ensures a stable beam position by limiting the laser beam refraction angle. By pre-setting the tilt angle of the laser lens 33, optical path calibration can be directly achieved in a fixed installation state, eliminating adjustment steps and avoiding sealing failures caused by moving parts. The tilted laser lens 33 causes individual beams that would otherwise be emitted from the convex lens of the laser module to undergo large-angle reflections. These reflected beams are then reflected again to the laser lens 33 and refracted. This refracted beam deviates significantly from the focal center, becoming invisible in the field of view, greatly improving the focusing effect of the laser module's emitted light spot and mitigating astigmatism and stray light issues.

[0036] Combination Figures 2 to 7As shown, in this embodiment, the light source protection unit 4 has a through hole 41 at its axial center for the drive unit 23 of the rotating drum 2 to pass through and be inserted into the switching module 51. The switching module 51 has a slot 52 corresponding to the drive unit 23. The axial through hole 41 refers to a through-hole that passes through the central axis of the light source protection unit 4. Specifically, it can be achieved by using a precision stamping process to form a cylindrical channel in the center of the metal light source protection unit 4. This through hole 41 is used to restrict the drive unit 23 to move only axially during rotation, avoiding gaps between components due to radial offset. The slot 52 refers to a groove structure provided inside the switching module 51 that matches the shape of the end of the drive unit 23. The depth and width of the slot 52 are configured to form a clearance fit with the drive unit 23, ensuring smooth sliding of the drive unit 23 in the slot while limiting its range of motion to reduce mechanical wear. When the rotating drum 2 is rotated, the torque generated by the rotation of the rotating drum 2 is directly transmitted to the inner wall of the slot 52 through the drive unit 23, triggering the switching of the switch module contacts to realize the switching of the working state of the lighting source. Meanwhile, the gap between the through hole 41 and the drive unit 23 is controlled within the range that the sealing ring can cover, allowing the mating surface between the light source protection unit 4 and the rotating cylinder 2 to be completely sealed by the waterproof structure. This solution, through the longitudinal insertion structure of the axial through hole 41 and the slot 52, changes the connection between the drive unit 23 and the switching module 51 to axial direct linkage, eliminating the impact of lateral gaps on waterproof performance. The optimization of the mechanical linkage structure reduces component wear during operation, making the light effect switching action more stable and reliable.

[0037] In this embodiment, a fixed middle section 6 is provided between the gripping part 1 and the rotating drum 2. The two ends of the fixed middle section 6 connect the gripping part 1 and the light source protection part 4, and waterproof sealing rings are provided between the fixed middle section 6 and both the gripping part 1 and the light source protection part 4. The fixed middle section 6 is a rigid connecting component with a hollow structure, specifically made of metal or engineering plastic. Its two ends are respectively provided with threaded interfaces or snap-fit ​​structures to achieve detachable connection with the gripping part 1 and the light source protection part 4. The waterproof sealing ring is an elastic sealing element, such as an O-ring or rubber gasket, which fills the microscopic gaps between the connecting interfaces through pre-compression deformation, blocking the liquid penetration path. The fixed middle section 6 can be threaded to the gripping part 1 and the light source protection part 4 respectively, forming a stable mechanical support structure to prevent loosening due to relative displacement of components during the rotation of the rotating drum 2. Specifically, an annular groove can be provided on the connecting end face of the fixed middle section 6 and the gripping part 1, with an O-ring embedded in the groove. When the gripping part 1 and the fixed middle section 6 are tightened, the O-ring is compressed and deformed to close the radial gap. The connection end face between the fixed middle section 6 and the light source protection part 4 is also provided with an annular groove and an O-ring. The axial clamping force of the light source protection part 4 deforms the sealing ring, forming a double waterproof barrier. This solution divides the connection interface into two independent sealing areas by adding the fixed middle section 6, reducing the risk of single seal failure. At the same time, the rigid support of the fixed middle section 6 suppresses the direct force on the grip part 1 and the light source protection part 4 when the rotating drum 2 rotates, reducing the possibility of structural deformation. It effectively prevents external liquid from seeping into the internal electronic component area from the connection between the grip part 1 and the rotating drum 2. At the same time, the split connection structure improves the overall mechanical stability and avoids component loosening or seal failure due to frequent rotation operations.

[0038] Combination Figure 2 and Figure 6As shown, in the preferred embodiment, the outer wall of the light source protection part 4 is uniformly provided with a plurality of slots 42 around its circumference, and the inner wall of the rotating cylinder 2 is provided with a plurality of protrusions that match the slots 42. When the rotating cylinder 2 rotates to its position, the protrusions engage with the slots 42 to provide a damping force that restricts the rotating cylinder 2 from continuing to rotate. The slots 42 refer to groove structures provided on the outer circumferential surface of the light source protection part 4. Specifically, they can be formed by machining into equally spaced rectangular or arc-shaped grooves, used to cooperate with the protrusions on the inner wall of the rotating cylinder 2 to form a physical limit. The protrusions refer to raised structures provided on the inner wall of the rotating cylinder 2. Specifically, they can be made by injection molding or metal stamping processes to create protrusions with a shape complementary to the slots 42, used to embed into the slots 42 and generate mechanical interference when the rotating cylinder 2 rotates to its position. The damping force refers to the mechanical resistance generated by the contact between the protrusions and the slots 42. Specifically, different intensities of tactile feedback can be achieved by adjusting the angle of the protrusion's slope or the depth of the slots 42. When the rotating cylinder 2 rotates relative to the light source protection part 4, the inner wall protrusions slide along the outer wall of the light source protection part 4. When the rotating drum 2 rotates to a predetermined angle, the protrusion and the corresponding slot 42 are fully aligned and embedded. At this time, the friction generated by the contact between the protrusion and the side wall of the slot 42 forms rotational resistance. This resistance provides tactile feedback to the operator to confirm the switch is in place, and also prevents the rotating drum 2 from continuing to rotate through the mechanical interference between the protrusion and the side wall of the slot 42. The slots 42, which are evenly distributed around the circumference of the light source protection part 4, ensure that each light source switching position has the same operating torque and positioning accuracy. By using a purely mechanical slot 42 in conjunction with the protrusion, the positioning accuracy is ensured while avoiding the use of additional electronic components, making the overall structure more compact and reliable. The damping force generated by the mechanical interference can precisely control the rotation angle and improve the operating feel. It effectively solves the problem of over-switching caused by the lack of physical limits during the rotation of the rotating drum 2, and provides a clear stop point for each light source switch through the mechanical cooperation between the protrusion and the slot 42. The perceptible tactile feedback during operation improves the accuracy of mode switching, while the damping force formed by mechanical interference enhances the operating quality of the equipment. The mating structure of the slot 42 and the protrusion further improves the reliability of the rotation positioning of the rotating drum 2 and avoids the phenomenon of incorrect switching of the light source due to misoperation.

[0039] In a preferred embodiment, the light source protection unit 4 is made of metal and is provided with at least one of the following: heat dissipation fins, heat dissipation plate, heat dissipation holes, and heat dissipation channels to improve heat dissipation performance. The metal material refers to a material with a high thermal conductivity, specifically aluminum alloy or copper alloy, which allows for rapid absorption and transfer of heat generated by the light source. The heat dissipation fins are sheet-like structures extending from the outer surface of the light source protection unit 4, specifically thin sheets arranged in parallel or radial patterns, increasing the heat dissipation surface area and accelerating heat exchange with the air. The heat dissipation plate is a plate-like structure covering the outside of the light source protection unit 4, specifically a raised platform integrally formed with the metal substrate, increasing local thickness to improve heat conduction efficiency. The heat dissipation holes are through holes 41 penetrating the wall of the light source protection unit 4, specifically circular or square holes, promoting airflow and forming a heat convection path. The heat dissipation channel is an airflow space enclosed by the heat dissipation fins or heat dissipation plate, specifically the gap between adjacent fins, connecting the interior of the light source with the external environment to enhance heat exchange. The metal light source protection unit 4 utilizes its high thermal conductivity to quickly dissipate heat generated by the light source to the external surface. The heat dissipation fins increase the contact area between heat and ambient air by expanding the heat dissipation surface. The heat sink strengthens the heat conduction path through localized thickening, the heat dissipation holes reduce localized temperatures by creating airflow, and the heat dissipation channels accelerate heat diffusion by guiding airflow. These features work synergistically to ensure that the heat generated by the light source is continuously and efficiently dissipated, preventing performance degradation or structural deformation due to temperature accumulation. By combining metal materials with a composite heat dissipation structure, a significant improvement in heat dissipation efficiency is achieved without the need for additional active cooling devices, while maintaining structural compactness and airtightness. This effectively solves the problem of shortened lifespan of light source components due to insufficient heat dissipation. Through optimized design of the heat conduction path and airflow path, the lighting fixture maintains a stable operating temperature even under prolonged high-load operation, while avoiding increased size or reduced waterproofing performance due to the addition of heat dissipation components.

[0040] In this embodiment, the grip portion 1 is suitable for installing a power supply 7 and a control component 5. The power supply 7 is a dry cell battery or a rechargeable battery. The outer surface of the grip portion 1 is suitable for having a concave-convex surface 11 to enhance friction. Installing the power supply 7 and the control component 5 inside the grip portion 1 means integrating the power supply module and the circuit control module into the same internal space of the housing. Specifically, this can be achieved by using a cavity layout or a layered stacking structure, so that the power supply 7 and the control component 5 form a compact assembly in physical space, reducing circuit cross-interference. Wherein, the power supply 7 is a dry cell battery or a rechargeable battery means that a standardized battery compartment structure is adopted to be compatible with disposable batteries and rechargeable batteries. Specifically, this can be achieved by using a battery bracket with spring contacts and a universal charging interface design, which allows for battery type interchangeability through a standardized interface. Wherein, the concave-convex surface 11 refers to the regular or irregular texture structure formed on the outer wall of the grip portion 1. Specifically, this can be achieved by using a knurling process, a dotted raised array, or a wavy stripe processing process, which increases the friction coefficient of the contact surface and improves grip stability. The power supply 7 and control components 5 are integrated into the cylindrical cavity of the grip portion 1. A cover is provided at the front end of the cavity for battery replacement, and a sealed circuit board mounting slot is provided at the rear end. The uneven surface 11 forms a diamond-shaped grid pattern on the outer wall of the grip portion 1 using a roll forming process. For example, the pattern depth is controlled within the range of 0.5 mm to 1.5 mm, and the spacing between adjacent patterns is 2 mm to 4 mm. This method achieves efficient utilization of the internal space of the grip portion 1, and the textured structure of the outer surface provides stable friction under various grip postures, effectively preventing accidental slippage when hands are sweaty or wet. The design, compatible with both dry-cell and rechargeable batteries, expands the device's applicable scenarios, meeting both the need for rapid battery replacement in emergency situations and supporting daily cyclic charging usage.

[0041] Combination Figure 7 As shown, in this embodiment, the light-emitting part 22 of the rotating cylinder 2 is configured as a fan-shaped opening, a frustum-shaped opening, or a square opening for light output. The driving part 23 is configured as a plug that matches the switching module 51, and anti-slip texture 21 is provided on the outer side of the rotating cylinder 2. The light-emitting part 22 refers to the light-transmitting area provided on the rotating cylinder 2. Specifically, the opening shape can be processed by metal stamping or injection molding, and the opening edge is chamfered to reduce light scattering. This design ensures that the light path is accurately aligned with the lighting source in the working state by adapting to the beam distribution characteristics of different light sources. The anti-slip texture 21 refers to the concave and convex structure distributed on the outer surface of the rotating cylinder 2. Specifically, it can be processed by diamond knurling or transverse groove processing. This structure increases the contact friction, enabling precise control of the rotation angle of the rotating cylinder 2 during one-handed operation. When the rotating cylinder 2 rotates around the light source protection part 4, the plug undergoes axial displacement in the slot 52 of the switching module 51, triggering the corresponding circuit contact to close. The anti-slip texture 21 increases the operating resistance, preventing slippage when hands are wet or gloves are worn, and ensuring that each rotation can accurately position the preset gear.

[0042] Combination Figure 4 As shown, in a preferred embodiment, an actuator 8 may also be provided in the grip wall. The actuator 8 is connected to a control system to enable or disable the lighting assembly based on the different actions performed by the user on the actuator 8. The control system is a control circuit assembly. The actuator 8 may be a push-button switch used to control the power supply or de-energization of the entire lighting assembly. For example, when the rotating drum 2 rotates to a certain light source, it does not need to rotate back to the blank (off) position. The current light source can be turned on or off through the actuator 8. If the same light source is needed for the next use, it can be activated through the actuator 8. If a different light source is needed for the next use, it can be switched through the rotating drum.

[0043] In summary, this embodiment, through reasonable structural design and innovative technical solutions, solves the problems of inconvenient operation, poor waterproof performance, and limited functionality in the prior art, providing users with an efficient, convenient, and reliable lighting fixture.
