Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more specifically to a one-handed lighting fixture. 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, in dim or dark outdoor environments, traditional handheld lights (such as flashlights and emergency lights) generally suffer from the problem of being inconvenient 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 fixtures on the ground or in cluttered environments, the lack of active identification features often results in the following technical defects:

[0004] 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.

[0005] 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.

[0006] 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.

[0007] 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.

[0008] 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.

[0009] In addition, 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. Utility Model Content

[0063] The following description is intended to disclose the present invention so that those skilled in the art can 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 present 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 present invention.

[0064] Those skilled in the art should understand that, in the disclosure of this utility model, 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 utility model 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 limitations on this utility model.

[0065] 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.

[0066] The instruction manual includes the attached diagram. Figures 1 to 13 A handheld lighting fixture according to a preferred embodiment of the present invention is described. 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 achieve a wide field of view illumination according to a preset structure. The support system 20 provides support for the lighting system 10 so that the lighting system 10 can provide illumination within a preset angle and range.

[0067] 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.

[0068] 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.

[0069] 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 forward illumination component 11 to provide a wide viewing angle and a wide range of illumination. Specifically, the forward illumination component 11 of the lighting 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 present invention, the circumferential illumination circumferential angle β is greater than 300 degrees. This light emission mode in which forward light and circumferential light complement and work synergistically not only greatly increases the illumination angle, but also greatly extends the illumination extension length, thereby solving the problem of prior art that needs to balance and hesitate between widening the field of view and converging light sources. In other words, the forward illumination component 11 only needs to provide forward illumination with sufficient intensity within the angle range of 0 to α. The circumferential lighting component 12 only needs to provide illumination at a preset angle. The circumferential lighting component 12 supplements the light source at a preset angle in the direction of extension of the central axis L, thereby greatly increasing the field of view provided by the lighting system 10 without increasing the illumination angle too much, thus ensuring both light intensity and increasing the field of view.

[0070] It is worth mentioning that 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.

[0071] 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 present 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 plays a converging role.

[0072] 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.

[0073] 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.

[0074] According to this preferred embodiment of the present 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 submerged 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.

[0075] 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.

[0076] 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.

[0077] The circumferential lighting component 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 present 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 present 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 multiple 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 present 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.

[0078] 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.

[0079] The circumferential lighting support structure 222 further includes a bracket 2222, which is mounted together with the receiving cylinder 2211 to prevent unnecessary rotation relative to each other. Specifically, the receiving cylinder 2211 has a partition wall 22111. The two sides of the partition wall 22111 respectively form the receiving cavity 221101 and a fixing cavity 221102, wherein the bracket 2222 extends into the fixing cavity 221102 and is fixed within it. More specifically, the bracket 2222 includes a plug-in portion 22221, a circumferential light source positioning structure 22222, and a retainer 22223, wherein the plug-in 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-in portion 22221 and the circumferential light source positioning structure 22222. The connector 22221 is inserted into the fixed cavity 221102.

[0080] 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. Even without additional heat dissipation components, the heat dissipation effect provided by the receiving cylinder 2211 itself can meet the requirements.

[0081] According to this preferred embodiment of the present invention, the outer contour cross-section of both the insertion portion 22221 and the fixing cavity 221102 is a large semi-circle. Further, the insertion portion 22221 forms three insertion posts 222211 arranged in a triangular pattern. Correspondingly, the partition wall 22111 has three insertion holes 221110, so that the three insertion 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. Further, the bracket 2222 and the receiving cylinder 2211 are fixed together by screws.

[0082] 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.

[0083] The outer surface of the positioning post 222221 extends in a curved cylindrical shape around the central axis L with a predetermined radius.

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.

[0086] 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.

[0087] 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 circumferential 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.

[0088] According to this preferred embodiment of the present 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.

[0089] More specifically, the light-diffusing cover 1231 further includes a pair of positioning wings 12313, which extend integrally from the cover 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 cover body 12311 and the light-diffusing protrusion 12312 in a preset manner at a preset position, thereby realizing the installation and fixation of the cover body 12311 and the light-diffusing protrusion 12312, and thus the light-diffusing cover 1231 is installed and fixed as a whole.

[0090] According to this preferred embodiment of the present 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 mixing space, and after being mixed in the mixing space 120, it further reaches the light-diffusing mask 1231, thereby being emitted to the outside of the light-diffusing mask 1231 in a more uniform manner.

[0091] 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.
