Description

Technical Field

[0001] The present application relates to the field of fire-fighting lighting equipment, and in particular to a portable energy-saving lighting device for urban fire-fighting. Background Art

[0002] Lighting devices play a vital role in urban firefighting operations. Whether it is rescue at the fire scene, fire detection inside the burned building, or firefighters' action guidance in a smoke-filled environment, reliable and efficient lighting equipment is one of the key factors to ensure the smooth progress of rescue work.

[0003] Traditional fire lighting equipment mainly includes portable searchlights, head-mounted lighting fixtures and on-site lighting fixtures. Among them, they usually have high power and can provide strong lighting brightness. At the fire scene, they can illuminate a longer distance and a larger range, which helps firefighters observe the fire, find trapped people and escape routes. Head-mounted lighting fixtures can free up firefighters' hands for rescue operations, such as carrying the wounded, breaking down obstacles, etc., to improve rescue efficiency. On-site lighting fixtures usually have multiple lamp heads or a large light-emitting surface, which can evenly illuminate an area within a certain range. They are suitable for illuminating the rescue operation area at the fire scene, such as setting up temporary medical points, command centers, etc.

[0004] However, due to the various complex environments during firefighting operations, it is often not possible to choose just one, and multiple lighting fixtures need to be carried. In addition, since there are many important life-saving materials that need to be carried in the rescue environment, it is particularly troublesome to carry on-site lighting fixtures, which greatly affects the mobility of firefighters.

[0005] Therefore, it is necessary to provide a portable energy-saving lighting device for urban fire fighting to solve the above problems. Summary of the invention

[0006] In order to solve the problem that the on-site lighting devices for traditional firefighting operations are inconvenient to carry and affect the mobility of firefighting operations, the present application provides a portable energy-saving lighting device for urban firefighting.

[0007] The portable energy-saving lighting device for urban fire fighting provided in this application adopts the following technical solution:

[0008] A portable energy-saving lighting device for urban fire fighting, comprising: a main lamp holder; a main lamp body, detachably connected to the upper side of the main lamp holder and capable of independent lighting; a plurality of side guard arms, arranged around the main lamp holder, the lower end of each side guard arm being rotatably connected to the main lamp holder so that the side guard arm can be rotated to fit the peripheral wall of the main lamp body or unfolded to be perpendicular to the main lamp body; a plurality of auxiliary light panels, respectively fixed to each side guard arm, and as each side guard arm is unfolded, each auxiliary light panel can independently illuminate upward.

[0009] By adopting the above technical solution, the portable energy-saving lighting device for urban fire fighting can achieve a compact structure and be easy to carry while ensuring efficient lighting. The design of the main lamp body and multiple auxiliary light panels enables a wide lighting range, which not only meets the needs of large-area lighting, but also adapts to the lighting needs of different scenes. The main lamp body can be detachably connected to the main lamp holder, which is convenient for single or combined use, and improves flexibility. Multiple side guard arms can be rotated and folded to save space. When unfolded, multiple auxiliary light panels can expand the lighting range. In complex fire fighting environments, the lighting layout can be flexibly adjusted according to the needs of different scenes, improving the flexibility and adaptability of lighting, reducing the trouble of carrying multiple lighting fixtures, and improving the mobility of firefighters.

[0010] Optionally, it also includes: multiple support arms, which are respectively arranged between adjacent side guard arms, and the lower end of each support arm is hinged to the main lamp holder, so that each support arm can be rotated to fit the peripheral wall of the main lamp body or rotated to the lower side of the main lamp holder to support the main lamp holder.

[0011] By adopting the above technical solution, the rotation of the support arm can realize the rapid switching between different use states. When no additional support is needed, the support arm can be close to the peripheral wall of the main lamp body, reducing the occupied space and facilitating carrying; when stable placement is required, the support arm can be unfolded to the lower side of the main lamp holder to provide stable support and ensure the stability of the lighting device in complex environments. This design effectively improves the portability and adaptability of the lighting device and meets the diverse lighting needs in urban firefighting operations.

[0012] Optionally, the side guard arm includes: a swing seat, one end of which is rotatably connected to the main lamp seat; a movable arm, one end of which is rotatably connected to one end of the swing seat away from the main lamp seat, and the other end is a free end, the rotation axis of the movable arm and the swing seat is perpendicular to the rotation axis of the swing seat and the main lamp seat, and the auxiliary light panel is fixed to the movable arm; the rotation of the movable arm can make the auxiliary light panel face toward or away from the main lamp body.

[0013] By adopting the above technical solution, the side arm structure design enables the auxiliary light panel to flexibly adjust the lighting direction. The combined design of the swing seat and the movable arm realizes the precise adjustment of the auxiliary light panel at different angles, so that the light can be concentrated on a specific area according to actual needs, improving the flexibility and adaptability of lighting. At the same time, this structure is also easy to store and unfold, reducing the overall volume of the device, enhancing portability and maneuverability, and facilitating firefighters to quickly deploy and use it on site.

[0014] Optionally, the side guard arm also includes: a solar panel, which is movably arranged in the movable arm and can extend from the side of the movable arm; and a battery, which is fixed in the main lamp holder and electrically connected to the solar panel.

[0015] By adopting the above technical solution, the solar panels can be pulled out to generate electricity using solar energy and store it in batteries. When the firefighting operation is completed and there is sunlight, the lighting device can be replenished with electricity, thereby extending the lighting time, improving energy utilization efficiency, reducing dependence on external power sources, and enhancing the endurance of the lighting device in complex environments.

[0016] Optionally, the main lamp body includes: two portable lamp bodies, which are symmetrically arranged on the upper side of the main lamp holder, the lower ends of the two portable lamp bodies are horizontally plugged into the main lamp holder, and the two portable lamp bodies can be spliced ​​together to form the main lamp body.

[0017] By adopting the above technical solution, a modular design of the main lamp body is realized. The two portable lamp bodies can be used separately or spliced ​​into a complete main lamp body, which improves the flexibility and portability of the lighting device. In actual use, a single lamp body or a combined lamp body can be selected according to different needs, which not only saves space, but also reduces the burden on firefighters and enhances the overall practicality of the device.

[0018] Optionally, it also includes: a positioning frame, which is vertically fixed to the upper side of the main lamp holder and is in an inverted U shape. An accommodating space is formed between the positioning frame and the main lamp holder for accommodating the main lamp body. The side of the positioning frame facing away from the main lamp holder is a transparent plate for illuminating the main lamp body through the transparent plate.

[0019] By adopting the above technical solution, the design of the positioning frame can not only effectively protect the main lamp body and prevent it from being damaged during transportation and use, but also ensure that the light emitted by the main lamp body can be evenly irradiated to the required area through the transparent plate, thereby improving the lighting effect and safety of use. At the same time, the accommodation space formed by the positioning frame enables the main lamp body to be more firmly installed on the main lamp holder, thereby enhancing the structural stability of the entire device.

[0020] Optionally, both sides of the side guard arm are formed with pressing inclined surfaces; when the support arm is rotated upward to abut against the main lamp holder, the two sides of the support arm can abut against the pressing inclined surfaces to limit the unfolding of the side guard arm.

[0021] By adopting the above technical solution, when the support arm rotates upward to contact the main lamp holder, the two sides of the support arm will contact the pressing inclined surface on the side guard arm, thereby effectively limiting the deployment of the side guard arm, ensuring the compactness and stability of the entire device when not in use, and facilitating carrying and storage. At the same time, in the use state, this design can prevent the side guard arm from accidentally deploying, avoiding interference with the firefighter's operation, and improving the safety and reliability of the device.

[0022] Optionally, it also includes: a slip ring that slides vertically inside the main lamp holder; multiple locking rods that are arranged in the main lamp holder at positions corresponding to each support arm, one end of each locking rod is hinged to the slip ring, and as the slip ring moves upward, it can push each locking rod to protrude out of the peripheral wall of the main lamp holder, and as the slip ring moves downward, it can drag each locking rod to retract to the peripheral wall of the main lamp holder; a locking groove is opened in each support arm; as each support arm rotates upward to fit the peripheral wall of the main lamp holder, each locking rod protrudes from the peripheral wall of the main lamp holder and can be inserted into each locking groove to limit the swing of the support arm.

[0023] By adopting the above technical solution, the arm can be effectively locked and unlocked. When the slip ring moves upward, the locking rod is pushed out of the peripheral wall of the main lamp holder and inserted into the locking groove on the arm, thereby ensuring that the arm is stably fitted to the peripheral wall of the main lamp holder to prevent it from accidentally unfolding. When the slip ring moves downward, the locking rod retracts to the peripheral wall of the main lamp holder, releasing the arm so that it can be freely rotated to the desired position, which is convenient for adjusting the lighting angle and supporting stability. This design not only improves the portability and ease of operation of the device, but also enhances the stability and reliability of the structure.

[0024] Optionally, it also includes: a plurality of locking posts vertically fixed on the lower side of the slip ring, corresponding to the position of each of the support arms, so that as the slip ring moves downward, each of the locking posts can protrude from the lower side of the main lamp holder, and as the slip ring moves upward, each of the locking posts can retract into the main lamp holder; a plurality of locking holes are respectively opened in each of the support arms, so that when the support arms rotate downward to the limit position, each of the locking posts can move downward and be inserted into the locking holes to limit the swing of each of the support arms.

[0025] By adopting the above technical solution and utilizing the cooperation between the lock column and the lock hole, the arm can be locked when it is rotated downward to the extreme position, thereby preventing the arm from being damaged by excessive rotation or affecting the stability of the lighting device. At the same time, this locking mechanism also facilitates quick unlocking and adjustment of the arm position, thereby improving the device's ease of operation and its ability to adapt to different usage scenarios.

[0026] Optionally, it also includes: a screw sleeve, which is threadedly connected to the slip ring and rotatably connected to the main lamp holder, and can drive the slip ring to move vertically as the screw sleeve rotates.

[0027] By adopting the above technical solution, the slip ring is moved vertically by rotating the screw sleeve, thereby indirectly controlling the movement of the lock rod, lock column and other components. This transmission method is simple and reliable, and can accurately adjust the position of each component, thereby achieving effective control of the status of each component of the lighting device, facilitating the operation of firefighters and ensuring the stability and reliability of the lighting device in different states.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] The lighting device achieves diversity and flexibility in lighting functions through a unique design of the main light body, side guards and auxiliary light panels. The main light body is detachable and can illuminate independently to meet basic lighting needs; multiple side guards can rotate and drive the auxiliary light panels to unfold or fold. When unfolded, the auxiliary light panels can illuminate upward independently, greatly expanding the lighting range. In complex firefighting and rescue environments, firefighters can quickly adjust the lighting layout according to the actual scene, reduce dependence on a variety of lighting fixtures, and effectively improve the mobility of firefighters on the scene, enabling them to carry out rescue work more efficiently, such as switching lighting in different areas inside the fire building, and flexible lighting in a larger rescue site.

[0030] In terms of the overall structure, the setting of the support arm significantly enhances the practicality and stability of the lighting device. The support arm can rotate between adjacent side guard arms, can fit the peripheral wall of the main lamp body for storage and carrying, and can also be rotated to the lower side of the main lamp holder to play a supporting role. This allows the lighting device to be stably placed in various complex terrains, ensuring the continued effectiveness of the lighting. At the same time, the cooperation between the pressing slope on the side guard arm and the support arm, as well as the locking mechanism composed of components such as the slip ring, locking rod, locking groove, locking column, and locking hole, further enhance the stability of the structure and the convenience of operation. When stored, it can effectively prevent the accidental deployment of the side guard arm and the support arm. When in use, the status of each component can be accurately controlled to avoid displacement or damage of components due to shaking and other factors, ensuring that the lighting device can always operate reliably in the harsh environment of firefighting operations;

[0031] The design of the main lamp body being made up of two portable lamp bodies improves the portability and practicality of the lighting device. The portable lamp body can be disassembled, which is convenient for firefighters to flexibly arrange according to different scenes, and can be quickly spliced ​​into the main lamp body when large-area strong light illumination is required. In addition, the solar panels installed in the side arm guards and the batteries in the main lamp holder make full use of solar energy resources. During the firefighting operation, as long as there is sunlight, the solar panels can generate and store electricity, effectively extending the lighting time, reducing dependence on external power sources, improving energy utilization efficiency, and ensuring the continuous power supply of the lighting device during long-term rescue missions. This energy self-sufficiency is particularly important, especially at some fire scenes where power supply is inconvenient or interrupted, and provides strong support for the smooth progress of firefighting and rescue work.

[0042] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0043] The inventor of this application found that traditional fire lighting equipment has the problem of multiple lighting fixtures needing to be carried at the same time in urban firefighting operations, which affects the mobility of firefighters. To this end, this application mainly adopts the following portable energy-saving lighting device design, which achieves the goal of improving the lighting effect while taking into account portability and energy saving, and significantly improves the efficiency and safety of urban firefighting operations. Example

[0044] Reference Figure 1 and Figure 2 The embodiment of the present application provides a portable energy-saving lighting device for urban fire fighting, including a main lamp holder 1, a main lamp body 2, a plurality of side guard arms 3 and a support arm 4.

[0045] The main lamp holder 1 has a rectangular cross-section, and each corner of the main lamp holder 1 forms an inclined surface. A main lamp body 2 is vertically arranged on the upper side of the main lamp holder 1, and the main lamp body 2 is detachably connected to the main lamp holder 1. A handle 11 is formed on the lower side of the main lamp holder 1. A battery is arranged in the main lamp holder 1. When the main lamp body 2 is connected to the main lamp holder 1, the main lamp body 2 will be electrically connected to the battery in the main lamp holder 1 to realize power supply to the main lamp body 2. At the same time, a backup power supply is also fixed in the main lamp body 2. When the main lamp body 2 is disassembled from the main lamp holder 1, the main lamp body 2 can still generate lighting independently through the backup power supply.

[0046] Specifically, a positioning frame 12 is fixed on the upper side of the main lamp holder 1, and the positioning frame 12 is in an inverted U shape as a whole. The positioning frame 12 includes two vertically arranged upright poles 121, and a protective plate 122 is horizontally fixed at one end of the two upright poles 121 away from the main lamp holder 1. The cross-sectional shape of the protective plate 122 is the same as the cross-sectional shape of the main lamp holder 1, and the protective plate 122 is a transparent plate. In this way, a storage space is formed between the positioning frame 12 and the main lamp holder 1 for accommodating the main lamp body 2, and the lower side of the main lamp body 2 is formed with an inverted T-shaped horizontal plug-in board, and the upper side of the main lamp holder 1 is formed with a horizontal plug-in slot adapted to the horizontal plug-in board. After the main lamp holder 1 is adapted to the horizontal plug-in slot through the horizontal plug-in board, it will be completely fitted in the space between the positioning frame 12 and the main lamp holder 1. Since the protective plate 122 is a transparent plate, on the basis of protecting the main lamp body 2, it also ensures that the light source of the main lamp body 2 can be emitted through the transparent plate.

[0047] Reference Figure 3 In order to improve the emergency functionality of the lamp, the main lamp body 2 can be formed by splicing two portable lamp bodies 21, that is, the cross-sections of the two portable lamp bodies 21 are triangular and symmetrically arranged. When the two portable lamp bodies 21 are spliced ​​together, the main lamp body 2 can be formed. In this way, during firefighting operations, the main lamp can be used by two people at the same time.

[0048] Furthermore, in other embodiments of the present application, the number of portable lamp bodies 21 is not limited to two, and more portable lamp bodies 21 may be provided to meet the needs of more people.

[0049] In this embodiment, four side guard arms 3 are provided, and the four side guard arms 3 are also vertically arranged, and the four side guard arms 3 are respectively attached to the four vertical side surfaces of the main lamp holder 1. The lower ends of the four side guard arms 3 can be movably connected to the lower side of the main lamp holder 1, so that each side guard arm 3 can swing relative to the main lamp holder 1.

[0050] Reference Figure 3 and Figure 4Specifically, each side guard arm 3 includes a swing seat 31 and a movable arm 32. The swing seat 31 is used to connect the movable arm 32 and the main lamp holder 1. One end of the swing seat 31 is hinged to the lower part of the side wall of the main lamp holder 1 through a 90° rotation damping, so that the guard arm can rotate from a vertical fit to the side wall of the main lamp holder 1 to a horizontal state within a range of 90°. The movable arm 32 is rotatably connected to the swing seat 31, and the rotation axis of the movable arm 32 and the main lamp holder 1 is perpendicular to the swing line of the swing seat 31 and the main lamp holder 1. A connecting shaft 33 with the same extension direction as the side guard arm 3 is arranged between the movable arm 32 and the swing seat 31. One end of the connecting shaft 33 rotates on the swing seat 31, and the other end slides on the movable arm 32. A plug-in structure is also arranged between the movable arm 32 and the swing seat 31. The plug-in structure should include two groups symmetrical with the connecting shaft 33 as the center. For example, a convex column and a groove can be used to prevent the convex column and the groove from being too loose. The convex column can also be set as an elastic column, a magnetic column, etc. to limit the need to apply a certain force to disengage the two after the convex column is inserted into the groove, thereby preventing the movable arm 32 and the swing seat 31 from being too loose. Thus, by combining the connecting shaft 33 and the plug-in structure, the plug-in structure can cooperate every time the movable arm 32 rotates 180 degrees relative to the swing seat 31 from the initial position, thereby limiting the relative position of the movable arm 32 and the swing seat 31 .

[0051] The side arm 3 can be fixed with a sub-light board 34 on one side facing the main lamp holder 1, and the sub-light board 34 is electrically connected to the battery of the main lamp holder 1. The sub-light board 34 can also be provided with an independent power switch. When the side arm 3 drives the sub-light board 34 to rotate toward the main lamp and fit the main lamp body 2, the sub-light board 34 can be turned off, so that only the main lamp body 2 is used for lighting. When the side panel drives the sub-light board 34 to rotate to a horizontal position, the sub-light board 34 can be turned on to further expand the lighting range. In addition, the main lamp holder can be twisted 1180 degrees relative to the swing seat 31, so that the sub-light board 34 is facing downward in a horizontal state, and then the swing seat 31 is rotated until the side arm 3 fits the main lamp body 2, and the sub-light board 34 is turned on, which can also realize lighting within the range around the main lamp body 2, further expanding the lighting range, meeting a variety of different lighting requirements, and being suitable for rescue in various complex environments.

[0052] The side guard arm 3 is also provided with a solar panel 35, which is electrically connected to the battery of the main lamp holder 1 for charging the battery.

[0053] In one embodiment of the present application, the solar panel 35 is arranged on the side of the side guard arm 3 away from the main light panel. In this way, when not in operation, the side guard arm 3 is unfolded, and the movable arm 32 is twisted so that one side of the solar panel faces upward, so that the battery can be charged through the solar panel 35.

[0054] In another embodiment of the present application, the solar panel 35 is movably arranged inside the side guard arm 3 and can be pulled out from both sides of the side guard arm 3. That is, two solar panels 35 are slidably arranged inside each side guard arm 3 along its width direction, and the two solar panels 35 are arranged overlappingly. When in use, the two solar panels 35 can be pulled out from the opposite sides of the side guard arm 3 to collect solar energy, and when not in operation, the two solar panels can be pushed into the side guard arm 3 to better protect the solar panels 35. Of course, based on this embodiment, the solar panel 35 can also be continuously arranged on the side of the side guard arm 3 away from the main light panel, and the working surfaces of all the solar panels 35 only need to be set on the same side.

[0055] Through this arrangement, solar energy can be effectively collected, thereby improving energy utilization and reducing losses in charging the lighting device.

[0056] In other embodiments of the present application, handle grooves 22 can be opened on both sides of the main lamp body 2 for easy carrying, and a fluorescent rescue rope can be accommodated in the handle groove 22. Before operation, when the side arm is not unfolded, the fluorescent rescue rope in the handle groove 22 can be illuminated by turning on the auxiliary light panel 34 of the side arm guard 3, and the fluorescent rescue rope can be charged by utilizing the light-absorbing and luminous properties of the fluorescent substance in the fluorescent rescue rope. Therefore, when needed, the fluorescent rescue rope can be taken out to build a clear luminous line between two people, so as to clearly identify the position of the people in a dark environment.

[0057] In this embodiment, there are four support arms 4, each of which is vertically arranged and located between adjacent side guard arms 3. The lower ends of the support arms 4 are hinged to the lower side of the main lamp holder 1. As the support arms 4 swing upward, they can fit into the inclined surface of the main lamp holder 1 and the adjacent sides of the adjacent side guard arms 3. The lower ends of the support arms 4 are also integrally formed with a resistance member 41. After the support arms 4 swing downward to the oblique lower side of the main lamp holder 1, the resistance member 41 can resist the lower side of the main lamp holder 1, thereby realizing the support of the support arms 4 to the main lamp holder 1.

[0058] Reference Figure 5 and Figure 6 Furthermore, a receiving space is formed inside the main lamp holder 1, and a slip ring 13 is vertically slidable in the receiving space. Lock rods 14 are provided at positions corresponding to the support arms 4 in the main lamp holder 1, and one end of each locking rod 14 is hinged to the slip ring 13. Locking columns 15 are vertically fixed on the lower side of each slip ring 13 at positions corresponding to the support arms 4. As the slip ring 13 moves upward, it can push each locking rod 14 to protrude from the peripheral wall of the main lamp body 2 and drag the locking columns 15 to retract into the main lamp holder 1; as the slip ring 13 moves downward, it can drag each locking rod 14 to retract to the peripheral wall of the main lamp holder 1 and push each locking column 15 to protrude from the lower side of the main lamp holder 1.

[0059] Each support arm 4 is further provided with a locking slot 42 , and each abutting member 41 of each support arm 4 is further provided with a locking hole 43 .

[0060] As each arm 4 rotates upward to fit against the peripheral wall of the main lamp holder 1, each locking rod 14 protrudes from the peripheral wall of the main lamp holder 1 and can be inserted into each locking groove 42 to limit the swing of the arm 4, so that the arm 4 is in a folded state. As each arm 4 rotates downward to the limit position, that is, when the abutment 41 abuts against the bottom side of the main lamp holder 1, each locking column 15 moves downward and can be inserted into each locking hole 43 to limit the swing of each arm 4, thereby achieving stable support of the main lamp holder 1.

[0061] Reference Figure 1 and Figure 6 The lower side of the main lamp holder 1 is also rotatably connected with a screw sleeve 16 with a vertical axis. The screw sleeve 16 is threadedly connected to the slip ring 13. As the screw sleeve 16 rotates, the slip ring 13 can be driven to move vertically.

[0062] In summary, the above-described structure can achieve effective locking and unlocking of the support arm 4. When the slip ring 13 moves upward, the locking rod 14 is pushed to protrude from the peripheral wall of the main lamp holder 1 and is inserted into the locking groove 42 on the support arm 4, thereby ensuring that the support arm 4 is stably fitted to the peripheral wall of the main lamp holder 1 to prevent it from accidentally unfolding. When the slip ring 13 moves downward, the locking rod 14 retracts to the peripheral wall of the main lamp holder 1, releasing the support arm 4 so that it can be freely rotated to the desired position, which is convenient for adjusting the lighting angle and supporting stability. By utilizing the cooperation of the lock column 15 and the lock hole 43, the support arm 4 can be locked when it is rotated downward to the extreme position, preventing the support arm 4 from excessive rotation and causing damage or affecting the stability of the lighting device. At the same time, this locking mechanism also facilitates quick unlocking and adjustment of the position of the support arm 4, improving the device's ease of operation and ability to adapt to different usage scenarios.

[0063] Reference Figure 4 and Figure 5 Furthermore, both sides of the swing seat 31 of the side guard arm 3 form a pressing inclined surface 311, that is, the cross section of the swing seat 31 is an isosceles trapezoid, that is, the side of the swing seat 31 that can fit the main lamp holder 1 is the bottom surface of the isosceles trapezoid, and the side of the swing seat 31 that is away from the main lamp holder 1 is the top surface of the isosceles trapezoid. When the movable arm 32 swings to fit the main lamp holder 1, the rotating support arm 4 fits the main lamp holder 1, and the positions of the swing seat 31 on both sides of the support arm 4 can also contact the pressing inclined surface 311 of the swing seat 31. This arrangement can achieve that the side guard arm 3 cannot be swung before the support arm 4 is unfolded, and the side guard arm 3 can be unfolded only after the support arm 4 is unfolded, so as to achieve the locking effect of the side guard arm 3. The compactness and stability of the entire device when not in use are ensured, and it is easy to carry and store.

[0064] The implementation principle of this application is:

[0065] When conducting firefighting operations, firefighters can directly carry the lighting device to the dangerous location to perform operations. According to different usage scenarios, the lighting device can at least achieve the following different display forms:

[0066] Form 1: The handle 11 of the portable main lamp holder 1 is illuminated by the main lamp body 2.

[0067] Form 2: first unlock the support arm 4, unfold the support arm 4, open the side arm guard 3, then twist the movable arm 32 to make the auxiliary light panel 34 face outward, then fold the side arm guard 3, then fold the support arm 4, and lock the support arm 4. In the active state, the main light body 2 can be used to illuminate synchronously with the side light panel.

[0068] Form three: first unlock the support arm 4, then rotate the support arm 4 to the bottom of the main lamp holder 1, and through the cooperation of the lock column 15 and the lock hole 43, the support arm 4 can be locked when it is rotated downward to the limit position, and then unfold the side arm 3, so that the auxiliary light panel 34 faces upward, turn on the auxiliary light panel 34, and through the cooperation of the auxiliary light panel 34 and the main lamp body 2, the range lighting in a fixed position is realized.

[0069] Form 4: Based on Form 3, the main lamp body 2 can be directly disassembled from the main lamp holder 1 to achieve portable independent lighting, and realize mobile lighting for firefighters to continue working in addition to lighting at a fixed base location.

[0070] Form 5: After completing the firefighting operation and returning to the base, the state of Form 3 can be presented again during the day, and then the solar panel 35 can be pulled out to charge the battery of the main lamp holder 1.

[0071] In summary, the lighting device achieves diversity and flexibility in lighting functions through the unique design of the main lamp body 2, side arm guards 3 and auxiliary light panels 34. The main lamp body 2 is detachable and can illuminate independently to meet basic lighting needs; multiple side arm guards 3 can rotate and drive the auxiliary light panels 34 to unfold or retract. When unfolded, the auxiliary light panels 34 can illuminate upward independently, greatly expanding the lighting range. In complex firefighting and rescue environments, firefighters can quickly adjust the lighting layout according to the actual scene, reduce dependence on a variety of lighting fixtures, and effectively improve the mobility of firefighters on the scene, so that they can carry out rescue work more efficiently, such as lighting switching in different areas inside the fire building, and flexible lighting in a larger rescue site.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
