[0002] Camping lights are lighting tools designed for outdoor camping activities. They have multiple functions and features to adapt to different outdoor environments and usage requirements. Among them, the most basic function of camping lights is to provide light to illuminate the camping area and facilitate campers to carry out various activities, such as cooking, reading or walking at night. This type of camping light is generally a portable camping light that can be held in hand or hung in a tent or on a tree.

[0016] The protrusion is fixedly connected to the peripheral side of the lower part of the lifting rod, and is provided in plurality and is arranged one-to-one corresponding to the plurality of through grooves or the plurality of embedded grooves.

[0017] Furthermore, the outer diameter of the reflective platform is larger than the outer diameter of the shell.

[0018] Furthermore, the outer ring of the flexible ring is fixedly connected to the outer ring of the smaller diameter of the two adjacent annular light strips, and the inner ring is fixedly connected to the inner ring of the larger diameter, and the outer diameter of the smaller diameter of the two adjacent annular light strips is greater than the inner diameter of the larger diameter.

[0019] Furthermore, the focusing adjustment mechanism includes:

[0020] Two support columns are provided and are located between the reflective table and the shell, and two ends of the support columns are detachably connected to the reflective table and the shell respectively;

[0021] A plurality of plastic shaping columns are provided and are located between two of the support columns, and the plastic shaping columns are bent and deformed by external forces;

[0022] A reflector is fixedly connected to one side of the plastic shaping column close to the lifting rod, and a plurality of the reflectors together form an arc-shaped condenser shielding the outer side of the annular light strip, and two adjacent reflectors are flexibly connected.

[0023] Furthermore, the length of the plastic shaping column is greater than the maximum distance between the reflective platform and the housing.

[0024] Furthermore, an arc-shaped shaping hoop is arranged between the two supporting columns, and the two ends of the arc-shaped shaping hoop are respectively hinged on the two supporting columns. The arc-shaped shaping hoop is sleeved on the side of the arc-shaped focusing cover away from the lifting rod, and the plastic shaping column is provided with an accompanying part for achieving a tight fit between the part of the plastic shaping column close to the arc-shaped shaping hoop and the arc-shaped shaping hoop.

[0025] Furthermore, the accompanying member includes a strong magnetic block arranged on the inner arc side of the arc-shaped shaping hoop, and the plastic shaping column is made of ferromagnetic material.

[0026] Furthermore, the maximum diameter of the arc-shaped shaping hoop is not less than the maximum diameter of the plastic shaping column.

[0027] Furthermore, a first magnet is embedded in the reflective platform, a second magnet is embedded in the upper end of the shell, the first magnet and the second magnet are magnetically attracted to each other, and ferromagnetic sheets are flexibly connected to both ends of the reflective sheet.

[0028] In summary, the beneficial technical effects of this application are:

[0029] 1. When using the camping light of the present application, the lifting rod can be pulled out from the mounting hole of the housing so that the reflecting arc surface of the reflective table is at a certain distance from the annular light belt. At this time, the light emitted by the multiple annular light belts is reflected by the reflecting arc surface on the reflective table and diffused and irradiated toward the circumference of the reflective table, which can expand the lighting area of ​​the annular light belt when it is hoisted and installed; and as the lifting rod is pulled out more from the mounting hole, the lighting area of ​​the camping light of the present application is larger; and, since the annular light belt is arranged at the top of the housing, when the camping light of the present application is hoisted and used, the light of the annular light belt can be effectively prevented from directly entering the eyes, thereby reducing the glare effect on the user;

[0030] 2. When the lifting rod is stretched, the lifting rod can be rotated so that the lifting rod can drive the multiple overlapping annular light strips to unfold one by one during the lifting process. Then, as the lifting rod continues to move upward, the annular light strip will also be twisted to a certain extent, so that its inner circle is higher than its outer circle and presents a cone-like shape with a small top and a large bottom. Finally, the multiple annular light strips are connected to multiple flexible rings in a cone-like shape. That is, at this time, the illumination direction of some annular light strips is converted from vertically upward illumination to inclined upward illumination. The tilt angle of the annular light strip is different depending on the distance the lifting rod moves upward. Therefore, the overall illumination direction and illumination area of ​​the multiple annular light strips can be adjusted, the adjustment range of the lighting area can be further expanded, and the lighting area adjustment of the camping lamp when it is mounted on the ground, suspended, or placed on a table can be realized.

[0031] 3. By arranging hinged arc-shaped shaping hoops on two supporting columns, when the arc-shaped shaping hoops are turned over, different parts of the plastic shaping columns on different reflective sheets can be adsorbed by the strong magnetic blocks arranged on the arc-shaped shaping hoops, so that the plastic shaping columns follow and bend to different degrees, thereby changing the position of the arc top of the reflective sheet, that is, changing the reflection direction of the reflective arc surface of the reflective sheet, thereby changing the reflection irradiation direction of the arc-shaped condenser in the vertical direction; and, since the adjustment of the overall arc top position of the arc-shaped condenser is achieved by the magnetic attraction of the strong magnetic blocks on the arc-shaped shaping hoops to the plastic shaping columns of ferromagnetic materials, there is no need to set up a complicated follow-up mechanism, the manufacturing cost is low and the operation is easy.

[0041] The following will be combined with the attached Figure 1-9The technical solution of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] The present application embodiment discloses a camping lamp with adjustable lighting area. Figure 1 and Figure 2 , which includes a housing 1, a PCB circuit board and control buttons, and the top of the housing 1 is provided with:

[0043] The annular light strip 21 is provided with a plurality of concentric rings which are sequentially arranged from the outside to the inside. In the specific setting, the main body of the annular light strip 21 is flexible, and can undergo both slight tensile deformation and torsional deformation in its radial direction. The annular light strip 21 is connected to the PCB circuit board and the control button, and the control button can be used to control the opening and closing of the annular light strip 21.

[0044] The flexible ring 22 is used to connect two adjacent ring-shaped light strips 21, and is specifically made of elastic rubber such as silicone. The outer ring of the flexible ring 22 is fixedly connected to the outer ring of the adjacent ring-shaped light strip 21 with a smaller diameter, and the inner ring is fixedly connected to the inner ring of the adjacent ring-shaped light strip 21 with a larger diameter. The outer diameter of the adjacent ring-shaped light strip 21 with a smaller diameter is greater than the inner diameter of the adjacent ring-shaped light strip 21 with a larger diameter, that is, the multiple ring-shaped light strips 21 are not only arranged in sequence from small to large in the radial direction, but also overlapped in sequence from roughly small and from bottom to top in the axial direction.

[0045] The lifting rod 31 is lifted and arranged in the middle of the shell 1, and is arranged through the hollow parts of the innermost ring light strip 21 and the flexible ring 22. Specifically, a mounting hole 11 is opened in the middle of the shell 1, and the lifting rod 31 is slidably arranged in the mounting hole 11, and a damping structure is arranged between the lifting rod 31 and the hole wall of the mounting hole 11, such as a damping rubber ring 312 embedded in the outer peripheral wall of the lifting rod 31, which can increase the sliding resistance of the lifting rod 31 in the shell 1, so that the lifting rod 31 can hover arbitrarily after being stretched.

[0046] Reflective table 32, reference Figure 3 and Figure 4 , fixedly connected to the top of the lifting rod 31, the outer diameter of the reflective platform 32 is larger than the outer diameter of the shell 1, and the end thereof close to the lifting rod 31 has a reflective arc surface 321, the inner arc side of the reflective arc surface 321 is arranged toward the annular light strip 21, and a reflective layer is arranged on the reflective arc surface 321; in addition, a hook 34 or a handle is fixedly connected to the end of the reflective platform 32 away from the lifting rod 31, and the camping light of the present application can be hung on a tree or a hook. In this embodiment, a hook 34 and:

[0047] A light zone adjustment mechanism, used to change the illumination area of ​​the plurality of annular light strips 21 when the lifting rod 31 is raised or lowered;

[0048] The focusing adjustment mechanism is disposed between the reflective platform 32 and the housing 1 and is used to reflect and focus the light emitted by the annular light strip 21 to a certain direction.

[0049] After such arrangement, when the camping light of the present application is used, the reflective table 32 can be pulled by the hook 34 to drive the lifting rod 31 to be pulled out of the mounting hole 11 of the shell 1, so that the reflective arc surface 321 of the reflective table 32 is a certain distance away from the annular light strip 21. At this time, after the annular light strip 21 is turned on by the control button, the light emitted by the plurality of annular light strips 21 is reflected by the reflective arc surface 321 on the reflective table 32 and diffused toward the reflective table 32 in a circumferential direction, thereby expanding the lighting area of ​​the annular light strip 21 when hoisted and installed; and as the lifting rod 31 is pulled out more from the mounting hole 11, the lighting area of ​​the camping light of the present application is larger; and, since the annular light strip 21 is arranged at the top of the shell 1, when the camping light of the present application is hoisted and used, the light of the annular light strip 21 can be effectively prevented from directly entering the eyes, thereby reducing the glare effect on the user.

[0050] Moreover, with the help of the setting of the light zone adjustment mechanism, the illumination area of ​​the multiple ring-shaped light strips 21 can be changed when the lifting rod 31 is raised or lowered, which can further expand the lighting area of ​​the camping lamp of the present application; and, with the help of the setting of the focusing adjustment mechanism, the illumination light emitted by the ring-shaped light strip 21 can be reflected and gathered in a certain direction, which is suitable for use when exploring the way with a portable camping lamp; therefore, with the help of the above-mentioned settings, the lighting area and usage method of the camping lamp of the present application can be greatly enriched, which can meet the complex lighting needs of outdoor camping as much as possible.

[0051] Specifically, refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 , the light zone adjustment mechanism includes:

[0052] The adjusting ring 33 is fixedly connected to the inner ring of the innermost annular light strip 21 or the flexible ring 22, and is provided with a plurality of through grooves 331 and embedded grooves 332 which are distributed in a circumferential array with equal spacing about the axis of the adjusting ring 33. The through grooves 331 penetrate the thickness direction of the adjusting ring 33, and the embedded grooves 332 are arranged at the end of the adjusting ring 33 away from the reflective table 32 and do not penetrate the adjusting ring 33. Specifically, in the present embodiment, the adjusting ring 33 is fixedly connected to the innermost annular light strip 21, and the thickness of the adjusting ring 33 is much greater than that of the annular light strip 21. There are four through grooves 331 and four embedded grooves 332. A first mark 71 for marking the position of the embedded groove 332 is arranged on the upper end surface of the adjusting ring 33.

[0053] The protrusion 311 is fixedly connected to the lower peripheral side of the lifting rod 31, specifically to the peripheral side of the lower middle part of the lifting rod 31. The protrusion 311 is provided with multiple and one-to-one correspondence with multiple through grooves 331 or multiple embedded grooves 332. The protrusion 311 is arranged in a long strip shape along the length direction of the lifting rod 31; and a second mark 72 for marking the position of the protrusion 311 is provided on the upper peripheral wall of the lifting rod 31. When the second mark 72 is aligned with the first mark 71 or the through groove 331, it means that the protrusion 311 is aligned with the embedded groove 332 or the through groove 331.

[0054] After such arrangement, when the lifting rod 31 is stretched, the lifting rod 31 can be rotated so that the second mark 72 thereon is aligned with the through groove 331. At this time, when the lifting rod 31 is pulled out of the mounting hole 11, the protrusion 311 on the lifting rod 31 passes through the through groove 331 on the adjustment ring 33, and the multiple annular light strips 21 remain in their original state. The lighting area can be adjusted by only pulling the lifting rod 31 to change the position of the reflective table 32.

[0055] If the lifting rod 31 is rotated so that the second mark 72 thereon is aligned with the first mark 71, when the lifting rod 31 is pulled out of the mounting hole 11, the protrusion 311 on the lifting rod 31 is embedded in the embedding groove 332 on the adjusting ring 33. As the lifting rod 31 continues to rise, the adjusting ring 33 moves up with the lifting rod 31, thereby driving the multiple annular light strips 21 in the overlapping state to unfold one by one.

[0056] Since the flexible ring 22 has good ductility, in the early stage when the lifting rod 31 continues to move upward, the multiple flexible rings 22 are stretched, so that the multiple annular light strips 21 can gradually unfold from the overlapping state; and then as the lifting rod 31 continues to move upward, the annular light strip 21 will also be twisted to a certain extent, so that its inner circle is higher than its outer circle and presents a cone-like shape with a small top and a large bottom, and finally the multiple annular light strips 21 are connected to the multiple flexible rings 22 to present a cone tower shape, that is, at this time, the illumination direction of some annular light strips 21 is converted from vertically upward illumination to inclined upward illumination, and the inclination angle of the annular light strip 21 is different depending on the upward distance of the lifting rod 31, thereby realizing the adjustment of the overall illumination direction and illumination area of ​​the multiple annular light strips 21, and further expanding the adjustment range of the lighting area, and realizing the adjustment of the lighting area when the camping light is mounted on the ground, suspended or placed on a table.

[0057] In addition, refer to Figure 3 and Figure 4 The above-mentioned focusing adjustment mechanism includes:

[0058] Two support columns 41 are provided and are located between the reflective table 32 and the housing 1. The two ends of the support column 41 are detachably connected to the reflective table 32 and the housing 1, respectively, and specifically can be snap-fitted or magnetically attracted. In this embodiment, the two ends of the support column 41 are magnetically attracted to the reflective table 32 and the top of the housing 1, respectively, and the support column 41 is bent and embedded between the reflective table 32 and the housing 1;

[0059] The plastic shaping column 42 is provided in plurality and is located between the two supporting columns 41. The plastic shaping column 42 is bent and deformed by external force. The length of the plastic shaping column 42 is greater than the maximum distance between the reflective table 32 and the housing 1, that is, the plastic shaping column 42 is also in an arc shape when it is extended between the housing 1 and the reflective table 32.

[0060] The reflective sheet 43 is fixedly connected to the side of the plastic shaping column 42 close to the lifting rod 31, and multiple reflective sheets 43 together enclose an arc-shaped focus cover 4 that covers the outside of the annular light strip 21. Two adjacent reflective sheets 43 are flexibly connected, and the side of the reflective sheet 43 close to the lifting rod 31 has a reflective surface. The upper and lower ends of the reflective sheet 43 are flexibly connected with magnetic sheets, so that the upper and lower ends of the reflective sheet 43 can be tightly fitted with the reflecting table 32 and the shell 1 to ensure the shading effect; or the reflective sheet 43 is an integrated type, such as a reflective cloth, on which multiple plastic shaping columns 42 arranged at intervals are fixedly connected to serve as a skeleton.

[0061] After such arrangement, when a portable camping lamp is used or the camping lamp is required to illuminate only one area or direction, the two support columns 41 and the plurality of reflectors 43 can be installed between the reflector 32 and the shell 1 after the reflector 32 is fully pulled out, and the distance between the two support columns 41 can be adjusted according to actual needs, so that the shading area of ​​the arc-shaped sunshade and the lighting area of ​​the camping lamp can be changed; and because both ends of the support columns 41 and the reflectors 43 are magnetically mounted on the shell 1 and the reflector 32, it is more convenient to install and remove the arc-shaped sunshade, so that the camping lamp of the present application can be used more flexibly.

[0062] In another feasible embodiment, in order to adjust the reflected light irradiation direction of the arc-shaped sunshade, refer to Figure 7 and Figure 8, an arc-shaped shaping hoop 5 is further arranged between the two support columns 41, the two ends of the arc-shaped shaping hoop 5 are respectively hinged on the two support columns 41, the maximum diameter of the arc-shaped shaping hoop 5 is not less than the maximum diameter of the plastic shaping column 42, the arc-shaped shaping hoop 5 is sleeved on the side of the arc-shaped focusing cover 4 away from the lifting rod 31, and the plastic shaping column 42 is provided with an accompanying piece for achieving a close fit between the part of the plastic shaping column 42 close to the arc-shaped shaping hoop 5 and the arc-shaped shaping hoop 5; specifically, the accompanying piece includes a strong magnetic block 51 arranged on the inner arc side of the arc-shaped shaping hoop 5, and the plastic shaping column 42 is made of ferromagnetic material, such as thin iron wire or spring steel wire. It should also be noted that the arc-shaped shaping hoop 5 here is arranged in a state where the two support columns 41 are respectively located at the two ends of the radial line of the shell 1.

[0063] In this way, by arranging hinged arc-shaped shaping hoops 5 on the two supporting columns 41, when the arc-shaped shaping hoop 5 is turned over, the strong magnetic block 51 arranged on the arc-shaped shaping hoop 5 can be used to adsorb different parts of the plastic shaping columns 42 on different reflective sheets 43, so that the plastic shaping columns 42 follow and bend to different degrees, thereby changing the position of the arc top of the reflective sheet 43, that is, changing the reflection direction of the reflective arc surface of the reflective sheet 43, and thus changing the reflection irradiation direction of the arc-shaped condenser 4 in the vertical direction; specifically, for example, when the arc-shaped shaping hoop 5 is turned up, the concave arc top of the arc-shaped condenser 4 is located at its upper part, and the reflection irradiation direction of the arc-shaped condenser 4 is obliquely downward, such as Figure 8 On the contrary, the arc-shaped shaping hoop 5 is turned down, so that the arc-shaped condenser 4 can reflect light in an obliquely upward direction, such as Fig. 9 As shown, the reflecting direction of the arc-shaped focusing cover 4 can be flexibly adjusted.

[0064] Furthermore, since the adjustment of the overall arc top position of the arc-shaped focusing cover 4 is achieved by the magnetic attraction of the strong magnetic block 51 on the arc-shaped shaping hoop 5 to the plastic shaping column 42 of the ferromagnetic material, there is no need to set up a complex follow-up mechanism, the manufacturing cost is low and the operation is easy.

[0065] Furthermore, in order to realize the magnetic installation of the arc-shaped focusing cover 4, refer to Figure 3 and Figure 4, a first magnet 61 is embedded in the reflective table 32, a second magnet 62 is embedded in the upper end of the shell 1, the first magnet 61 and the second magnet 62 are magnetically attracted to each other, and the two ends of the reflective sheet 43 are flexibly connected with ferromagnetic sheets or magnetic sheets that are magnetically attracted to the first magnet 61 or the second magnet 62. In this way, the upper and lower ends of the reflective sheet 43 can be tightly adsorbed on the reflective table 32 and the shell 1 to reduce the possibility of light leakage at the upper and lower ends of the arc-shaped focusing cover 4; and, through the magnetic attraction of the first magnet 61 and the second magnet 62, when the camping light of the present application is not in use, the reflective table 32 can be lowered to be attached to the shell 1, and the reflective arc surface 321 on the reflective table 32 can be well accommodated, and the reflective table 32 and the shell 1 are magnetically attracted to each other, which can prevent the reflective table 32 from automatically falling out when not in use, causing the circuit of the annular light strip 21 to be damaged outside.

[0066] And as some adaptive design, refer to Figure 4 The mounting hole 11 and the lifting rod 31 are both set to be two-stage, the aperture of the lower section of the mounting hole 11 is larger than the aperture of the upper section, and the outer diameter of the lower section of the lifting rod 31 is larger than the outer diameter of the upper end. When the lower section of the lifting rod 31 slides to the junction where the aperture of the mounting hole 11 is reduced, the reflective table 32 is at the position farthest from the housing 1. A plurality of through slots 12 for a plurality of protrusions 311 to pass through are provided on the hole wall of the upper section of the mounting hole 11, and the through slots 12 correspond to the through slots 331 on the adjusting ring 33 one by one, thereby ensuring the stability of the lifting rod 31 during lifting and moving, and avoiding the possibility of large shaking between the reflective table 32 and the housing 1 as much as possible.

[0067] The implementation principle of the lighting area adjustable camping lamp in the embodiment of the present application is:

[0068] When using the camping light of the present application, the reflective table 32 can be pulled by the hook 34 to drive the lifting rod 31 to be pulled out of the mounting hole 11 of the shell 1, so that the reflective arc surface 321 of the reflective table 32 is a certain distance away from the annular light strip 21. At this time, after the annular light strip 21 is turned on by the control button, the light emitted by multiple annular light strips 21 is reflected by the reflective arc surface 321 on the reflective table 32 and diffused toward the reflective table 32 in a circumferential direction, which can expand the lighting area of ​​the annular light strip 21 when it is hoisted and installed; and as the lifting rod 31 is pulled out more from the mounting hole 11, the lighting area of ​​the camping light of the present application is larger; and, since the annular light strip 21 is arranged at the top of the shell 1, when the camping light of the present application is hoisted and used, the light of the annular light strip 21 can be effectively prevented from directly entering the eyes, thereby reducing the glare on the user.

[0069] Moreover, by rotating the lifting rod 31, the lifting rod 31 can be moved upward to drive multiple annular light strips 21 to unfold in sequence, and finally the multiple annular light strips 21 are connected to the multiple flexible rings 22 to form a cone tower shape, that is, at this time, the illumination direction of some annular light strips 21 is converted from vertical upward illumination to inclined upward, so as to change the illumination area of ​​the multiple annular light strips 21, and the lighting area of ​​the camping light of the present application can be further expanded; and, with the help of the setting of the arc-shaped focusing cover 4 and the arc-shaped shaping hoop 5, the illumination light emitted by the annular light strip 21 can also be reflected and gathered in a certain direction, which is suitable for portable camping lights to be used for pathfinding and directional lighting; therefore, with the help of the above-mentioned setting, the lighting area and usage method of the camping light of the present application can be greatly enriched, and the complex lighting needs during outdoor camping can be met as much as possible.

[0070] 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.
