Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and more specifically to one-handed lighting fixtures. Background Technology

[0002] Handheld lighting fixtures are among the earliest portable lighting tools invented by humankind. Their development can be traced back to torches in primitive societies, and they went through stages such as oil lamps, candles, and gas lamps, until the invention of batteries and light bulbs at the end of the 19th century gave birth to the modern flashlight.

[0003] In recent years, handheld lighting fixtures have further integrated multi-functional design and scenario-based applications, while also developing towards lightweight, long battery life, and intelligent features. However, traditional spotlight designs still suffer from a narrow field of view, making it difficult to meet the wide-angle lighting needs in dim outdoor environments. There is an urgent need to optimize the optical system and its related structures to balance floodlight and long-range performance.

[0004] CN 212107941 U discloses a flashlight with both forward and circumferential lighting functions. This patent achieves light divergence or focusing by setting an independent lens group around each circumferential lighting bulb, thereby controlling the direction and shape of individual light spots. This circumferential lighting structure has a complex lens group structure, requires high assembly precision, and its circumferential light efficiency is easily attenuated by the outer casing. Multiple independent lens schemes easily create alternating bright and dark light spots in the usage area, resulting in poor lighting uniformity and limited heat dissipation efficiency. In this patent, the circumferential lighting assembly formed by a flexible lamp plate and bulbs is placed within the hollow circumferential wall of a positioning sleeve. Its support and heat dissipation mainly rely on the mechanical structure of the lamp body ring itself, resulting in a relatively indirect heat dissipation path and difficulty in dealing with heat accumulation problems during continuous high-power illumination. Furthermore, in CN212107941U, the lamp body ring used to fix the circumferential lighting group is fitted onto the lamp body base shaft 10. Therefore, the axial position of its circumferential lighting coincides with that of the forward lighting group, which not only causes mutual interference in heat dissipation between the two, but also results in a shorter axial illumination range, which cannot meet the illumination requirements of a wide field of view.

[0005] Furthermore, in dimly lit or dark outdoor environments, traditional handheld lights (such as flashlights and emergency lights) are generally difficult to locate after use. These products typically employ a single lighting function design, relying mainly on physical switches or buttons to control the light source's on / off state. When users temporarily place the lights on the ground or in cluttered environments, the lack of active marking functionality often results in the following technical defects: 1. Difficulty in visual positioning: Conventional lamps have no light source indication when they are off, and their appearance color is often similar to the ambient color (such as black or dark gray housing), making them difficult to quickly identify visually under low illumination conditions.

[0006] 2. Lack of active signal feedback: Most existing designs do not integrate location tracking or status indication modules. Users need to memorize the location or manually turn on the lights to find the device, which can easily cause time delays in emergency situations.

[0007] 3. Limitations of human-computer interaction: Traditional switching methods cannot provide remote sensing of device status, and there is a lack of sound and light-assisted positioning methods when the light fixture accidentally rolls off or gets stuck in mud or grass.

[0008] 4. Energy efficiency design contradiction: The complete power-off mode adopted to extend battery life is in fundamental conflict with the need for rapid positioning.

[0009] Current solutions largely rely on passive marking methods such as external reflective strips and fluorescent coatings, but these measures are completely ineffective in the absence of ambient light. Some high-end products attempt to achieve mobile phone positioning via Bluetooth, but their practicality is limited in outdoor scenarios without network coverage. How to improve the discoverability of lighting fixtures without significantly increasing power consumption has become a critical technical challenge for outdoor lighting equipment.

[0060] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0061] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0062] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0063] The instruction manual includes the attached diagram. Figures 1 to 21 A handheld lighting fixture according to a preferred embodiment of the present invention is illustrated. The handheld lighting fixture includes a lighting system 10 and a support system 20. The lighting system 10 is disposed on the support system 20 to be arranged according to a predetermined structure, thereby achieving a wide field of view illumination. The support system 20 provides support to the lighting system 10 so that the lighting system 10 can provide illumination within a predetermined angle and range.

[0064] The support system 20 includes a handheld component 21 and a light source support component 22. The handheld component 21 is mounted on the light source support component 22 and extends obliquely from the light source support component 22 to form a "pistol" shape. The shape of the handheld component 21 is designed as a handle for easy gripping. The light source support component 22 supports the lighting system 10 to enable it to emit light uniformly over a wide area.

[0065] The lighting system 10 includes a front illumination component 11 and a circumferential illumination component 12, wherein the front illumination component 11 provides forward illumination within a preset front illumination angle α with an axis L as the central axis.

[0066] The circumferential illumination component 12 is arranged circumferentially around the central axis L, thereby providing circumferential illumination within a predetermined length range around the central axis L within a circumferential illumination circumferential angle β. The circumferential illumination provided by the circumferential illumination component 12 cooperates and works synergistically with the forward illumination provided by the front illumination component 11 to provide a wide-angle, wide-range illumination. Specifically, the front illumination component 11 of the illumination system 10 provides variable-focus illumination forward within the forward illumination angle range. The circumferential illumination component 12 provides circumferential illumination, thereby greatly increasing the range of illumination. According to this preferred embodiment of the invention, the front illumination component 11 provides a forward illumination beam forward. The circumferential illumination component 12 is disposed behind the front illumination component 11 and arranged in a ring around the central axis L.

[0067] According to this preferred embodiment of the present invention, the circumferential illumination component 12 is not a completely closed ring around the central axis L, but has a region without circumferential light-emitting elements at the position corresponding to the handheld component 21, so as to avoid the installation position of the handheld component 21.

[0068] The circumferential illumination surrounds an angle β greater than 300 degrees and less than 360 degrees. This complementary and synergistic light-emitting method of forward and circumferential light not only greatly increases the illumination angle but also significantly extends the illumination range, thus solving the problem of prior art that requires a trade-off between widening the field of view and converging light sources. Specifically, the forward illumination component 11 only needs to provide sufficiently intense forward illumination within the 0 to α angle range. The circumferential illumination component 12 only needs to provide illumination at a preset angle. The circumferential illumination component 12 supplements the light source at a preset angle along the extension direction of the central axis L, thereby greatly increasing the illumination field of view provided by the lighting system 10 without significantly increasing the illumination angle, thus ensuring both light intensity and increased illumination field of view. More specifically, the front illumination component 11 projects a high-brightness beam forward along the central axis L from its emitting position within an angle range of 0 to α, while the circumferential illumination component 12 projects a circumferential beam outward around the central axis L within a certain length range behind the emitting position of the front illumination component 11. The two beams naturally converge in space to form a strong, wide-range three-dimensional light field, significantly improving the safety and environmental visibility of nighttime operations. More specifically, in the extension direction of the central axis L, the front illumination component 11 emits a beam in front of a preset position X, while the circumferential illumination component 12 emits a beam circumferentially behind the preset position X. The two beams converge and superimpose near the preset position X, thereby widening the axial illumination range. In the circumferential direction, the circumferential illumination component 12 emits light directly in the circumferential direction, thus significantly extending the illumination distance in the circumferential direction and effectively covering the side area of ​​the worker; combined with the penetrating power of the front illumination beam, the overall effect forms a three-dimensional lighting effect of "far in front and wide behind, cohesive inward and expanding outward". The lighting system 10 provides strong light intensity and a wide field of view, which can meet the harsh lighting needs in pitch-black environments such as at sea where there is no auxiliary lighting.

[0069] The front illumination assembly 11 includes a front illumination light source 111 and a concentrator 112, wherein the front illumination light source 111 and the concentrator 112 are mounted on the light source support assembly 22, so that the light generated by the front illumination light source 111 can be focused by the concentrator 112 to form forward illumination with the central axis L as the central axis and the forward illumination angle within the range of α. According to this preferred embodiment of the invention, the concentrator 112 is bowl-shaped. A reflective cavity 1121 is formed on the inner surface of the concentrator 112. The front illumination light source 111 is disposed inside the reflective cavity 1121 of the concentrator 112. The light emitted by the front illumination light source 111 enters the reflective cavity 1121 and is reflected by the inner surface of the concentrator 112 before being emitted forward. That is, the concentrator 112 reflects the light emitted by the front illumination light source 111 and acts as a converging element.

[0070] The front illumination assembly 11 further includes a light-emitting lens 113. The light-emitting lens 113 serves to transmit light, and it can also serve to converge light. For example, the light-emitting lens 113 is a convex lens, and the front illumination light source 111 is positioned at the focal point of the light-emitting lens 113.

[0071] The light source support assembly 22 includes a headlight support structure 221 and a circumferential lighting support structure 222, which provide structural support for the headlight assembly 11 and the circumferential lighting assembly 12, respectively. The headlight support structure 221 includes a receiving cylinder 2211 and a headlight cover 2212, wherein the condenser 112 and the headlight light source 111 are housed in a receiving cavity 221101 of the receiving cylinder 2211, and the light-emitting lens 113 is fixed by the headlight cover 2212 to a condenser opening 1120 of the condenser 112, so that the light emitted by the headlight light source 111 can be reflected and focused by the condenser 112 and then transmitted forward through the light-emitting lens 113.

[0072] According to this preferred embodiment of the invention, the light-emitting lens 113 and the front cover 2212 are sealed and fixed together, thereby preventing a loose seal between the light-emitting lens 113 and the front cover 2212 of the handheld lighting fixture. Consequently, even if the handheld lighting fixture is placed in water, water will not enter the handheld lighting fixture from between the light-emitting lens 113 and the front cover 2212. Specifically, the front cover 2212 includes a grip sleeve 22121 and a retaining ring 22122. The grip sleeve 22121 is made of a material that facilitates gripping and has a structure that facilitates gripping, thereby facilitating the assembly and disassembly of the front cover 2212. The retaining ring 22122 is integrally formed with the light-emitting lens 113 and is made of a waterproof material. The grip sleeve 22121 is fixedly attached to the outside of the retaining ring 22122. In other words, according to this preferred embodiment of the present invention, the front cover 2212 itself is an annular fixed structure integrally connected with the light-emitting lens 113, and together with the light-emitting lens 113, it realizes the sealing and fixing functions of the cover.

[0073] The concentrator 112 has a front light source through hole 1129, wherein the front light source 111 is fixed inside the receiving tube 2211 and passes through the front light source through hole 1129, and then enters a focusing space 11290 of the concentrator 112, thereby emitting light in the focusing space 11290, and being focused and reflected by the concentrator 112.

[0074] The circumferential lighting support structure 222 includes a circumferential lighting component carrier 2221, wherein the circumferential lighting component carrier 2221 has a mounting surface 222111, and the circumferential lighting component 12 is mounted on the mounting surface 222111. According to this preferred embodiment of the present invention, the mounting surface 222111 extends in the form of an open cylindrical curved surface, thereby facilitating the circumferential lighting component 12 mounted on the mounting surface 222111 to emit light circumferentially within a predetermined length range.

[0075] The circumferential lighting assembly 12 includes a circuit substrate 121 and a plurality of light-emitting elements 122, wherein the plurality of light-emitting elements 122 are arranged in a preset manner on the circuit substrate 121 and electrically connected in a preset manner. According to this preferred embodiment of the invention, the light-emitting element 122 includes a plurality of first light-emitting elements 122a and a plurality of second light-emitting elements 122b. The first light-emitting elements 122a are uniformly disposed on the circuit substrate 121. Specifically, the plurality of first light-emitting elements 122a are uniformly arranged with the same longitudinal spacing and the same lateral spacing between adjacent first light-emitting elements 122a. Similarly, the second light-emitting elements 122b are uniformly disposed on the circuit substrate 121. Specifically, the plurality of second light-emitting elements 122b are uniformly arranged with the same longitudinal spacing and the same lateral spacing between adjacent second light-emitting elements 122b. The second light-emitting elements 122b are disposed in the gaps between the first light-emitting elements 122a. More specifically, each second light-emitting element 122b is disposed at the center of four first light-emitting elements 122a arranged in a rectangular shape. According to this preferred embodiment of the invention, the light-emitting element 122 is divided into left and right parts, which are arranged as described above. The circuit substrate 121 of the circumferential illumination assembly 12 is attached to the outer side of the curved mounting surface 222111, so that the plurality of light-emitting elements 122 are arranged in a curved manner as described above to emit light circumferentially. More specifically, the mounting surface 222111 extends in a curved shape resembling the side surface of a cylinder, so that the light-emitting elements 122 of the circumferential illumination assembly 12 attached to the mounting surface 222111 emit light uniformly circumferentially. According to this preferred embodiment of the invention, the curved mounting surface 222111, which extends in a cylindrical side surface shape, is not a completely enclosed cylindrical side surface, but extends only on the top and left and right sides.

[0076] Specifically, the circumferential illumination component carrier 2221 includes a mounting portion 22211 and a fixing portion 22212, wherein the mounting portion 22211 and the fixing portion 22212 are integrally formed. The mounting portion 22211 extends at a predetermined angle in a columnar side shape and has a mounting surface 222111, wherein the predetermined angle γ of the columnar side shape of the mounting portion 22211 is greater than 300 degrees. The fixing portion 22212 is used to fix the position of the circumferential illumination component carrier 2221, preventing the circumferential illumination component carrier 2221 from undergoing unnecessary rotation, thereby ensuring that the illumination direction of the circumferential illumination component 12 mounted on the mounting portion 22211 does not undergo unnecessary rotation.

[0077] The circumferential lighting support structure 222 further includes a bracket 2222, wherein the bracket 2222 is mounted together with the receiving cylinder 2211 to avoid unnecessary rotation relative to each other.

[0078] The bracket 2222 and the receiving cylinder 2211 are arranged sequentially along the extension direction of the central axis L, thereby supporting the front illumination component 11 and the circumferential illumination component 12 at different positions along the axial direction. This results in a wider axial illumination field of view for the entire square and avoids overlap and interference between the front and circumferential illumination. Specifically, with the light direction of the front illumination component 11 as the front, the receiving cylinder 2211 is located in front of the bracket 2222, and the bracket 2222 is fixed to the rear end of the receiving cylinder 2211. The receiving cylinder 2211 is made of a metal material with good heat dissipation performance and has multiple heat dissipation grooves 22110, thus integrating the functions of receiving, fixing, and heat dissipation into one unit. Even without additional heat dissipation components, the heat dissipation effect provided by the receiving cylinder 2211 itself is sufficient to meet the requirements.

[0079] The receiving cylinder 2211 has a partition wall 22111. The receiving cavity 221101 and a fixing cavity 221102 are formed on both sides of the partition wall 22111, respectively, wherein the bracket 2222 extends into the fixing cavity 221102 and is fixed in the fixing cavity 221102.

[0080] The bracket 2222 includes a plug portion 22221, a circumferential light source positioning structure 22222, and a retainer 22223, wherein the plug portion 22221, the circumferential light source positioning structure 22222, and the retainer 22223 are integrally formed. The retainer 22223 is integrally formed between the plug portion 22221 and the circumferential light source positioning structure 22222. The plug portion 22221 is plugged into the fixing cavity 221102.

[0081] The fixed cavity 221102 has an arc-shaped cross-section. Correspondingly, the outer contour of the plug-in portion 22221 is also an arc shape. To prevent the bracket 2222 from rotating within the fixed cavity 221102, the plug-in portion 22221 is fixed within the fixed cavity 221102. According to this preferred embodiment of the invention, the plug-in portion 22221 and the partition wall 22111 are fixed together by screws to prevent relative rotation.

[0082] Specifically, the outer contour cross-section of the plug-in portion 22221 and the fixing cavity 221102 is an arc shape greater than 180°. The plug-in portion 22221 forms three plug-in posts 222211 arranged in a triangle. Correspondingly, the partition wall 22111 has three plug-in holes 221110, so that the three plug-in posts 222211 can be inserted respectively, thereby making the relative position of the bracket 2222 and the receiving cylinder 2211 more stable and avoiding unnecessary mutual rotation. Furthermore, three screws pass through the corresponding plug-in holes 221110 and are locked to the corresponding plug-in posts 222211, thereby fixing the bracket 2222 and the receiving cylinder 2211 together by screw fixing.

[0083] The circumferential light source positioning structure 22222 includes a positioning post 222221 and a retaining structure 222222, wherein the circumferential light-emitting component carrier 2221, on which the circumferential light-emitting component 12 is mounted, is sleeved on the positioning post 222221. The retaining structure 222222 is disposed outside the positioning post 222221 and extends in the same direction as the positioning post 222221. Specifically, the positioning post 222221 extends axially. The retaining structure 222222 is disposed outside the positioning post 222221, and its extending direction is parallel to the axial direction of the positioning post 222221, thereby forming a retaining space 222220 between the positioning post 222221 and the retaining structure 222222. The circumferential lighting component carrier 2221 is partially engaged in the retaining space 222220 between the positioning post 2222221 and the retaining structure 222222, thereby preventing the circumferential lighting component carrier 2221 from rotating relative to the positioning post 222221. Furthermore, the circumferential lighting component carrier 2221 is glued to the positioning post 222221.

[0084] The outer surface of the positioning post 222221 extends in a curved cylindrical shape around the central axis L with a predetermined radius. The central axis of the circumferential illumination component carrier 2221, which is disposed on the positioning post 222221, coincides with the central axis L of the positioning post 222221. The circuit substrate 121, which is attached to the circumferential illumination component carrier 2221, extends in a curved shape around the central axis L of the positioning post 222221 with a predetermined radius.

[0085] More specifically, the fixing portion 22212 of the circumferential illumination component carrier 2221 is engaged in the holding space 222220 between the positioning post 2222221 and the holding structure 222222, thereby preventing the circumferential illumination component carrier 2221 from rotating relative to the positioning post 222221. The fixing portion 22212 includes a connecting portion 222121 connected to the beginning and end of the mounting portion 22211 and at least one engaging portion 222122 integrally protruding from the connecting portion 222121. According to this preferred embodiment of the invention, the fixing portion 22212 includes two engaging portions 222122, which protrude from both ends of the connection between the connecting portion 222121 and the mounting portion 22211. Correspondingly, the holding structure 222222 has two engaging grooves 2222220 adapted to the engaging portions 222122. The two engaging parts 222122 are respectively engaged in the two engaging slots 2222220 to achieve positioning and fixation.

[0086] According to this preferred embodiment of the present invention, the connecting portion 222121 and the mounting portion 22211 are integrally formed into a cylindrical shape. The engaging portion 222122 protrudes integrally from the cylindrical structure formed by the connecting portion 222121 and the mounting portion 22211, thereby providing an engaging and positioning function and preventing unnecessary rolling of the cylindrical structure.

[0087] It is worth mentioning that the circumferential lighting component carrier 2221 is made of a metal material with excellent heat dissipation properties. Combined with the cylindrical space formed by its cylindrical structure, the circumferential lighting component carrier 2221 integrates circumferential light source support and heat dissipation functions, providing good heat dissipation performance without the need for additional heat dissipation components. Furthermore, the positioning column 222221 is also a hollow structure, further increasing the heat dissipation space.

[0088] The circumferential illumination assembly 12 further includes a light guiding structure 123 to guide the light emitted by the light-emitting element 122, thereby controlling the circumferential illumination direction and illumination range of the circumferential illumination assembly 12. Specifically, the light guiding structure 123 includes a uniform light mask 1231, which surrounds the light-emitting element 122 to guide the light emitted by the light-emitting element 122. In other words, the uniform light mask 1231 surrounds the circuit substrate 121, which extends with a predetermined radius of curvature, and the light-emitting elements 122, which are uniformly arranged on a curved surface, are covered by the uniform light mask 1231. The light emitted by the light-emitting element 122 continues to be emitted outward after passing through the uniform light mask 1231. There are multiple light-emitting elements 122, and the light emitted by the multiple uniformly arranged light-emitting elements 122 is emitted outward in a more uniform manner after passing through the uniform light mask 1231. The light-diffusing mask 1231 includes a mask body 12311 and a plurality of light-diffusing protrusions 12312 integrally protruding from the mask body 12311, wherein the plurality of light-diffusing protrusions 12312 are evenly distributed on the mask body 12311. At the same axial position, the distance between the mask body 12311 and the circuit substrate 121 remains the same, so that the light passing through the light-diffusing mask 1231 is uniformly guided in a preset manner.

[0089] According to this preferred embodiment of the invention, the cover 12311 extends in a curved shape around the central axis L. The light-diffusing protrusion 12312 formed on the cover 12311 extends in an arc shape around the central axis L. Specifically, the light-diffusing protrusion 12312 formed on the cover 12311 extends in a non-closed annular shape around the central axis L. In other words, each light-diffusing protrusion 12312 extends in an arc shape.

[0090] More specifically, the light-diffusing mask 1231 further includes a pair of positioning wings 12313, which extend integrally from the mask body 12311. Correspondingly, the retaining structure 222222 has a pair of positioning grooves 2222229, wherein the two positioning wings 12313 are respectively positioned in the corresponding positioning grooves 2222229 to support the mask body 12311 and the light-diffusing protrusion 12312 in a preset manner and at a preset position, thereby achieving the installation and fixation of the mask body 12311 and the light-diffusing protrusion 12312, and thus the light-diffusing mask 1231 is installed and fixed as a whole. The light-diffusing mask 1231 is conveniently and securely assembled to the retaining structure 222222 of the bracket 2222 by a plug-in method.

[0091] It is worth mentioning that this preferred embodiment achieves unified optical control of all light-emitting elements 122 through a uniform light-distributing cover 1231. This not only greatly simplifies the structural assembly process but also exhibits excellent circumferential illuminance uniformity. As a result, the circumferential lighting component 12 can radiate light energy uniformly in the circumference, effectively eliminating dark areas and light spots, and significantly improving lighting quality. Compared with the complex design of the prior art, which sets multiple independent lenses in different areas to achieve light divergence or focusing, this handheld lighting fixture achieves light control of all light-emitting elements 122 through only a curved surface structure. It achieves unified light guidance through a simple structure and uniform circumferential illumination through an arc-shaped structure.

[0092] After the light emitted by multiple light-emitting elements 122 is fully mixed inside the light-diffusing cover 1231, it is then modulated by the cover body 12311 and the light-diffusing protrusion 12312 of the light-diffusing cover 1231 to form a soft, glare-free circumferential light field. This ensures that the intensity of light illuminating any angle within the circumferential angle range is not significantly deviated, thus forming a uniform circumferential light field.

[0093] According to this preferred embodiment of the invention, the light-diffusing mask 1231 is composed of a first light-diffusing portion 12301 and a second light-diffusing portion 12302, wherein the first light-diffusing portion 12301 and the second light-diffusing portion 12302 are integrally formed. The distance between the first light-diffusing portion 12301 and the circuit substrate 121 remains constant in the direction extending along the central axis L. In the direction extending along the central axis L from the circumferential illumination component 12 to the front illumination component 11, the distance between the second light-diffusing portion 12302 and the circuit substrate 121 gradually increases until it is held in the position of the retainer 22223. The circumferential dimension of the retainer 22223 matches the edge dimension of the second light-diffusing portion 12302 of the light-diffusing mask 1231. The edge of the second light-diffusing portion 12302 of the light-diffusing mask 1231 is held in place by the holding body 22223, thereby the holding body 22223, the light-diffusing mask 1231, and the circuit substrate 121 together define a light-mixing space 120. The light-mixing space 120 is formed between the light-diffusing mask 1231 and the circuit substrate 121. The light emitted by the light-emitting element 122 enters the light-mixing space, and after being mixed in the light-mixing space 120, it further reaches the light-diffusing mask 1231. After being acted upon by the light-diffusing mask, it is emitted to the outside of the light-diffusing mask 1231 in a more uniform manner.

[0094] The light source support assembly 22 further includes a receiving shell 226. The receiving shell 226 includes a peripheral wall 2261 and a bottom wall 2262, wherein the peripheral wall 2261 and the bottom wall 2262 are integrally formed to form a receiving space 2260 and a receiving shell opening 22601 communicating with the receiving space 2260. The receiving shell 226 has a cylindrical structure with one end open. The headlight assembly 11, the circumferential lighting assembly 12, the circumferential lighting support structure 222 of the light source support assembly 22, and the receiving cylinder 2211 of the headlight support structure 221 are all received within the receiving space 2260. The headlight cover 2212 is detachably and sealed to the housing 226, so that the headlight assembly 11, the circumferential lighting assembly 12, the circumferential lighting support structure 222 of the light source support assembly 22, and the housing 2211 of the headlight support structure 221 are all sealed within the housing space 2260.

[0095] It is worth mentioning that the housing 226 is integrally molded from waterproof material, and the front light assembly 11, the circumferential lighting assembly 12, the circumferential lighting support structure 222 of the light source support assembly 22, and the housing 2211 of the headlamp support structure 221 are sealed within the housing space 2260 by the front light cover 2212, thereby forming a good waterproof structure, allowing the pistol light to be used in seawater. Compared with traditional handheld lights that have many connection interfaces, this handheld light significantly improves the overall waterproof performance and structural reliability by reducing the number of connection interfaces. More importantly, although the number of connection structures is reduced, this handheld light does not sacrifice any optical performance, heat dissipation efficiency, or structural stability.

[0096] Specifically, the housing 226 is made entirely of a transparent, waterproof material, allowing light that has been uniformly scattered by the light-diffusing shield 1231 to directly penetrate the housing 226. This achieves highly uniform circumferential illumination without the need for additional light-transmitting structures, significantly simplifying the optical path and reducing light loss. The light-emitting element 122 is arranged in an arc shape, with large spatial structures on both the inner and outer sides of the arc, which facilitates heat dissipation.

[0097] In terms of fixing method, the structure inside the housing 226 is first assembled as a whole, and then fixed through a triple constraint method of rear-end insertion fixing, lower slide rail positioning, and front-end pressure clamping to ensure structural stability. Specifically, the handheld lighting fixture is pistol-shaped. No corresponding light-emitting structure is provided at the location where the handheld component 21 is installed, i.e., the lower area of ​​the housing 226. Instead, this area is used as the fixing structure inside the housing 226. The slide rail design facilitates installation and maintains stable fixation, while also providing a support surface for gripping on the outside. On one hand, the circumferential lighting component 12 provides uniform circumferential illumination on the upper, left, and right sides, which is sufficient to meet the needs of outdoor operations. On the other hand, the ergonomic design of the pistol-shaped structure makes the grip more secure, and the housing 226's minimally ventilated, easily sealed structure provides a stable mounting position, thus ensuring both sealing performance and assembly efficiency and reliability. The inner surface of the fixing ring 22122 of the front cover 2212 is provided with threads, and the position where the housing 226 engages with the fixing ring 22122 is also provided with threads. Thus, the fixing ring 22122 and the housing 226 can be assembled together by engaging with the matching threads to achieve a detachable and waterproof structure.

[0098] It is worth mentioning that the grip sleeve 22121 is an adhesive-coated structure formed on the outside of the retaining ring 22122, wherein the grip sleeve 22121 extends to and wraps around the end 221221 of the retaining ring 22122 to form a waterproof rib 221211. Correspondingly, the peripheral wall 2261 of the housing 226 has a retaining edge 226101. When the front camera cover 2212 is installed on the peripheral wall 2261 of the housing 226, the waterproof rib 221211 fits tightly against the retaining edge 226101 of the peripheral wall 2261 to form the first line of defense of the waterproof structure. In other words, the waterproof rib 221211 provides a buffering and sealing effect between the end 221221 of the fixing ring 22122 and the retaining edge 226101 of the housing 226, so as to form the first line of defense of the waterproof structure of the lamp head of the handheld lighting fixture.

[0099] Furthermore, a sealing ring 40 is provided between the retaining ring 22122 and the housing 226 to form the second line of defense for the waterproof structure of the lamp head of the handheld lighting fixture. The threaded sealing structure between the retaining ring 22122 and the housing 226 forms the third line of defense for the waterproof structure of the lamp head of the handheld lighting fixture. The three lines of defense work together to achieve the preset waterproof effect, so that even if the handheld lighting fixture is placed in seawater for use, it can float on the water surface and work normally due to its good waterproof performance.

[0100] The triple waterproof structure gives the head of this handheld light excellent waterproof performance. (Reference) Figure 20 Users can hold the handheld light and place its head in a liquid, such as seawater, to observe both the seawater and the surface simultaneously.

[0101] At least one mounting hole 22621 is provided at the rear of the housing 226, i.e., on the bottom wall 2262 of the housing 226, to secure the structure inside the housing 226 and prevent the structure inside the housing 226 from rotating within the housing 226. According to this preferred embodiment of the invention, the number of mounting holes 22621 is three. The three mounting holes 22621 are arranged in a triangular pattern. Accordingly, three screws pass through each mounting hole 22621 and are then locked into the structure inside the housing 226.

[0102] More specifically, the three mounting holes 22621 are arranged in an equilateral triangle to ensure uniform force distribution and effectively suppress the displacement of internal components under shaking or impact.

[0103] Because the housing 226 is made of transparent material, its internal structure is clearly visible. The internal structure of the housing 226 is first assembled as a single unit, and then secured using a triple constraint system: a rear-end insertion fixation, a lower slide rail positioning, and a front-end pressure clamping. This ensures both structural stability and a clean appearance. Viewed from the outside of the handheld lighting fixture, the interior of the housing 226 appears uncluttered. Furthermore, this assembly method facilitates quick disassembly and maintenance.

[0104] The handheld lighting fixture further includes a buffer element 50, wherein the buffer element 50 includes a buffer ring body 51 and a positioning wall 52, wherein the positioning wall 52 extends integrally from the buffer ring body 51 at a predetermined angle. According to this preferred embodiment of the invention, the positioning wall 52 extends integrally from the buffer ring body 51 at a 90-degree angle. The buffer ring body 51 is disposed between the light-emitting lens 113 and the condenser 112 to provide buffering and shock absorption between them. The positioning wall 52 is disposed on the periphery of the receiving cylinder 2211 to fix the position of the buffer ring body 51 and prevent positional displacement or other situations that would hinder the installation and sealing performance of the handheld lighting fixture.

[0105] Furthermore, the housing 226 is a transparent structure, so that the light emitted by the light-emitting element 122 is mixed in the light mixing space 120 and then reaches the light uniform cover 1231, so that it is emitted to the outside of the light uniform cover 1231 in a more uniform manner, and then passes through the housing 226 and is emitted to the external environment. The housing 226 can further adjust the irradiation range of the circumferential light.

[0106] It is worth mentioning that the heat dissipation slots 22110 are arranged in a preset manner and are visible through the transparent housing 226, making them more aesthetically pleasing.

[0107] According to this preferred embodiment of the invention, the peripheral wall 2261 of the housing 226 includes a mounting portion 22611 and a light-transmitting portion 22612, wherein the mounting portion 22611 and the light-transmitting portion 22612 are integrally formed. The light-transmitting portion 22612 extends in a curved shape around the central axis L with a predetermined radius at any length position, thereby making the light transmitted from the light-transmitting portion 22612 more uniform. The mounting portion 22611 extends in a plane parallel to the central axis L. The mounting portion 22611 extends from a position corresponding to the circumferential lighting support structure 222 to a position corresponding to the receiving cylinder 2211, thereby providing a certain positioning function for the circumferential lighting support structure 222 and the receiving cylinder 2211. This prevents unnecessary rotation of the circumferential lighting support structure 222 and the receiving cylinder 2211 within the receiving space 2260 of the housing 226.

[0108] The mounting portion 22611 has a guide groove 2261101 and a guide flange 2261102. Correspondingly, the retaining structure 222222 has a mounting protrusion 2222221 to mate with the guide groove 2261101. The handheld assembly 21 has a mounting space 2101 to accommodate the guide flange 2261102. It is worth mentioning that the interaction between the mounting protrusion 2222221 and the guide groove 2261101 has multiple functions, including guiding, positioning, and fixing.

[0109] The light source support assembly 22 further includes a fixing plate 223 to connect and fix the bracket 2222 of the circumferential lighting support structure 222 to the bottom wall 2262 of the housing 226, thereby preventing unnecessary rotation of the bracket 2222 of the circumferential lighting support structure 222. This ensures that all components within the housing space 2260 of the housing 226 are stably fixed without unnecessary rotation or shaking. According to this preferred embodiment of the invention, the fixing plate 223 connects and fixes the bracket 2222 of the circumferential lighting support structure 222 to the bottom wall 2262 of the housing 226 by means of claw holes arranged in a double-sided isosceles triangle. This not only facilitates positioning during installation but also provides a better fixing effect.

[0110] It is worth mentioning that, according to the preferred embodiment of the present invention, the combination of fixing disc and slot fixing, along with the multiple fixing methods in which the shape of the receiving space 2260 matches the shape of the internally stored components, enables all components in the receiving space 2260 to be stably and firmly fixed. Even if some structures are damaged, this firm fixing effect is difficult to be destroyed.

[0111] The circumferential lighting component 12 is mounted on the surface of the circumferential lighting component carrier 2221. The circumferential lighting component carrier 2221, on which the circumferential lighting component 12 is mounted, is fitted into the positioning post 222221 of the bracket 2222. The light diffuser 1231 is covered around the circumferential lighting component 12 by being fixed to the holding structure 222222. Thus, the bracket 2222, the circumferential lighting component carrier 2221, the circumferential lighting component 12, and the light diffuser 1231 are fixed together to form a stable circumferential lighting module 001. There is no relative displacement between the components, ensuring that the lighting direction is accurate and constant. The first end of the sturdy circumferential lighting module 001 is further connected and fixed to the receiving cylinder 2211 by inserting and fixing the plug part 22221 into it. The tail end of the sturdy circumferential lighting module 001 is closed and fixed by the fixing plate 223, thereby making the structure of the circumferential lighting module 001 more stable. Furthermore, a circuit board 60 is fixed to the side of the fixing plate 223 away from the circumferential lighting module 001. Thus, the circumferential lighting module 001, the fixing plate 223, the receiving cylinder 2211, and the circuit board 60 together form an integrated unit 002 that can be assembled and disassembled as a whole. The integrated unit 002 is quickly positioned by sliding the mounting protrusion 2222221 into the guide groove 2261101, and is further positioned by plugging in the fixing plate 223 when it reaches the bottom wall 2262 of the housing 226, wherein electronic components such as circuit boards are snapped in place between the fixing plate 223 and the bottom wall 2262. At this point, the integrated unit 002 can no longer rotate within the housing 226, and the edge of the receiving cylinder 2211 protrudes beyond the housing 226. When the integral structure formed by the light-emitting lens 113 and the front cover 2212 is tightened at the front end of the receiving cylinder 2211, not only is the front light assembly 11 completely sealed within the housing 226, but the integrated unit 002 is further pressed by the axial pressure applied rearward, thereby firmly fixing the integrated unit 002 within the housing 226 through a three-sided fixing method.

[0112] The housing 226 is at a predetermined angle. When the housing 226 extends horizontally, the handheld component 21 extends approximately vertically and is disposed on the bottom side of the housing 226.

[0113] Understandably, when the handheld component 21 is removed from the housing 226, the lighting system 10 and the light source support component 22 form a single flashlight device, allowing the user to hold the housing 226 and adjust the illumination direction of the front light source 111 of the lighting system 10. When the handheld component 21 is installed in the housing 226, it extends longitudinally within the housing 226, allowing the user to hold it and adjust the illumination direction of the front light source 111 of the lighting system 10. In other words, through the detachable connection between the handheld component 21 and the housing 226, the handheld lighting fixture can be easily switched between two usage modes.

[0114] It is understood that when a user holds the handheld component 21, the handheld component 21 may not be horizontal, but may extend vertically or be positioned at a predetermined angle to the vertical. This allows the lighting direction of the lighting system 10 to be easily adjusted when the handheld component 21 is rotated. For example, when the handheld component 21 is rotated in the user's hand, it can rotate 360 ​​degrees, thereby allowing the lighting system 10 to rotate 360 ​​degrees to adjust its lighting direction to the desired position. Whether the user's hand is left or right, the user can rotate their hand around their wrist to adjust the position of the handheld component 21, thereby adjusting the lighting direction of the lighting system 10.

[0115] The lighting system 10 further includes a control module 14 and a power supply module 15. The control module 14 includes a control circuit and a control switch 142. The headlight 111 and the light-emitting element 122 are various light sources capable of emitting light, such as LEDs, OLEDs, fluorescent lamps, etc. The headlight 111 and the light-emitting element 122 are electrically connected to the control module 14 and the power supply module 15. When the control switch 142 is operated, the headlight 111 and the light-emitting element 122 emit light under the control of the control circuit and with the power supplied by the power supply module 15. The power supply module 15 is disposed in the support system 20.

[0116] According to this preferred embodiment of the invention, the control switch 142 is disposed on the handheld assembly 21 and electrically connected to the control circuit, such as being disposed in the handheld assembly 21 via a wire and electrically connected to the control circuit inside the housing 226.

[0117] The control switch 142 protrudes from the handheld component 21 and is configured as a button so that when the user holds the handheld lighting fixture in a gun-grip posture, the index finger can naturally reach it and perform the switching operation with one hand. When the control switch 142 is pressed, the lighting system 10 is activated to emit light. According to this preferred embodiment of the invention, the control switch 142 is used to control the on / off state and illumination mode of the front light source 111. Each press of the control switch 142 switches between three operating modes of the front light source 111: low brightness, medium brightness, and high brightness. Each press of the control switch 142 cycles through these modes sequentially: low brightness, medium brightness, high brightness, and off, repeating this cycle.

[0118] The control module 14 further includes a light adjustment structure 143 for adjusting the light emitted by the lighting system 10. The light adjustment structure 143 is positioned at the rear of the handheld lighting fixture so that when the operator holds the handheld lighting fixture in a gun-grip posture, their thumb can naturally reach it and perform the on / off operation with one hand. According to this preferred embodiment of the invention, the light adjustment structure 143 is used to control the on / off state and illumination mode of the circumferential lighting component 12. Each press of the light adjustment structure 143 switches the operating mode of the circumferential lighting component 12.
