Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and particularly to an LED lamp for outdoor camping. Background Art

[0002] LED lamps are mainly used for lighting during camping. Adjustable light reflectors are arranged around the lamps, such as folding aluminum foil or plastic with a high reflectivity coating, and an openable light shield is reserved to achieve directional light projection. When the light reflector is retracted and the opening is fully open, 360° wide-angle lighting is achieved, which is suitable for overall lighting of the campsite. When the light reflector is unfolded and the opening is adjusted to 30° - 60°, the light is concentrated and projected onto a designated area, such as a cooking area or a workbench. In order to adjust the opening angle of the light reflector and consider the portability during camping, the light reflector is generally made flexible.

[0003] When a flexible light shield is used in an outdoor camping lamp, it is required to keep it in a tensioned state and have a consistent curvature. If the flexible light shield is slack or wrinkled, irregular bumps and depressions will form on the surface, resulting in diffuse reflection of light or leakage of light from the gaps, destroying the directional lighting effect. And the curvature of the light shield determines the reflection angle of the light. If the curvature is inconsistent, such as local depressions or protrusions, the reflected light will form bright and dark stripes or light spots, affecting the lighting uniformity. Generally, the light reflector is wound around a column. When the column rotates, it will wind or release the light reflector. And in order to ensure the tension of the light reflector, a torsion spring is arranged on the column. Since the greater the torsion spring is stretched, the greater the elastic force is, when pulling the light reflector out from the round rod, the pulling force on the light reflector will gradually increase, which is not conducive to the smooth adjustment of the flexible light reflector. During the stretching process, the light reflector may be deformed or torn due to the suddenly increased pulling force locally. And the torsion spring is in a high-tension state for a long time, accelerating metal fatigue and possibly shortening the service life. Summary of the Invention

[0004] The object of the present invention is to solve the problems in the background art, and propose an LED lamp for outdoor camping, in which when adjusting the opening angle of the light reflector, the light reflector can always be in a state of uniform force and keep tensioned, avoiding wrinkles on the light reflector and affecting the reflection effect.

Detailed implementation manners

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1, as Figures 1 to 7As shown in the figure, an LED lamp for outdoor camping proposed by the present invention includes a lamp body 1. A tripod 101 is detachably installed at the bottom of the lamp body 1, and a lamp shade 102 is fixedly installed at the top of the lamp body 1. It also includes a first connecting seat 2 fixedly installed on both the upper and lower sides of the lamp body 1. A rollable reflector 3 is detachably installed on the first connecting seat 2. The reflector 3 can reflect light. Since excessive scattered light may interfere with the activity rhythm of wild animals, and when the camping ground is densely populated, directional lighting can prevent strong light from directly shining on other tents or rest areas. Through the reflector 3, the target area can be accurately covered, such as the cooking table, tool operation area or tent entrance, reducing the waste of light in the ineffective area and prolonging the battery life.

[0020] Multiple curvature control components 4 are installed on the reflector 3. Through the curvature control components 4, the curvature of each position of the reflector 3 can be ensured to be consistent, so that the reflector 3 can maintain uniform reflection characteristics, avoiding the reflected light from forming bright and dark stripes or light spots, which affects the lighting uniformity.

[0021] Furthermore, the curvature control component 4 includes a plurality of limit blocks 401 fixedly installed on the reflector 3. The limit blocks 401 are evenly divided by a ring. Adjacent two limit blocks 401 are rotatably connected. Since the reflector 3 is flexible, and when the reflector 3 is pulled out, the two columns connected to the reflector 3 will apply a pulling force to the reflector 3, which causes the reflector 3 to present a planar state between the two columns. If the reflector 3 is attached to the glass cover on the lamp body 1, there will be no gap between the lamp body 1 and the reflector 3, resulting in a reduction in the heat dissipation effect of the lamp body 1 and it is not suitable for long-term use.

[0022] When the reflector 3 is pulled out and bent, the reflector 3 will drive the limit blocks 401 to move. Adjacent two limit blocks 401 will abut against each other, and the abutting limit blocks 401 will limit each other. A plurality of limit blocks 401 can form a ring, and the ring supports the reflector 3. Furthermore, the reflector 3 can maintain a constant curvature, which can effectively improve the directional lighting effect, avoid local depressions or protrusions, and prevent the reflected light from forming bright and dark stripes or light spots, which affects the lighting uniformity.

[0023] Such as Figures 8 to 20As shown in the figure, the LED lamp of this embodiment further includes a tension member 7. The tension member 7 is connected to the reflector 3 and applies a winding force to the reflector 3, thereby applying a pulling force to the reflector 3, so that the reflector 3 always has a tendency to be wound and contracted, and thus it can ensure that the reflector 3 is in a tensioned state. The tension member 7 includes an elastic component that applies a winding force to the reflector 3 and a release component that disconnects the elastic component from the reflector 3 when the reflector 3 is subjected to a pulling force. When reducing the opening and closing angle of the reflector 3, it is necessary to stretch the reflector 3. At this time, the connection between the reflector 3 and the elastic component is disconnected, which can prevent the reflector 3 from being subjected to a pulling force when the reflector 3 is stretched, and avoid the reflector 3 driving the elastic component to move, resulting in a gradual increase in the elastic force of the elastic component. There is a loosening prevention component for fixing the elastic component to prevent the elastic force of the elastic component from being released. Since the elastic force of the elastic component will be applied to the reflector 3, and after the position of the reflector 3 is fixed, it cannot be contracted, and thus the elastic force of the elastic component cannot be released. However, when the connection is disconnected, the elastic force of the elastic component will be released. At this time, the loosening prevention component is used to limit the elastic component, which can prevent the elastic force of the elastic component from being released, so that the elastic component can always maintain the elastic force and tension the reflector 3.

[0024] As an implementation manner, one end of the reflector 3 is fixedly installed with a connecting rod 5, and the other end is installed with a receiving rod 6. The receiving rod 6 includes two mounting boxes 601. A winding rod 602 is rotatably installed between the two mounting boxes 601. One end of the reflector 3 is fixedly connected to the winding rod 602. When the winding rod 602 rotates, it will wind or release the reflector 3. A handle 603 and a storage box 604 are fixedly installed between the two mounting boxes 601. The storage box 604 is provided with a first notch 605 through which the reflector 3 passes. When the connecting rod 5 is fixed, pulling the handle 603 can drive the winding rod 602 to move and stretch the reflector 3, so that the reflector 3 drives the winding rod 602 to rotate.

[0025] Among them, a connecting block 202 is fixedly installed on the first connecting seat 2 and a slideway 201 is provided. A slider 203 is slidably installed in the slideway 201. There is a damping between the slider 203 and the slideway 201. The slider 203 cannot move along the slideway 201 under a small pulling force. The connecting rod 5 is detachably connected to the connecting block 202, and the receiving rod 6 is detachably connected to the slider 203. When the connecting rod 5 is connected to the connecting block 202 and the receiving rod 6 is connected to the slider 203, one end of the reflector 3 is fixed at this time. Pulling the receiving rod 6 to move can drive the other end of the reflector 3 to perform a cylindrical motion along the slideway 201. At this time, the reflector 3 subjected to the pulling force will drive the winding rod 602 to rotate, and the rotating winding rod 602 can release the reflector 3 and maintain a constant curvature under the action of the curvature control component 4.

[0026] As an implementation, the installation box 601 includes a connection hole 6011 provided on the installation box 601. A connecting plate 6012 is slidably installed in the connection hole 6011. A flexible sealing plate 6013 is fixedly installed between the connecting plate 6012 and the connection hole 6011. The winding rod 602 is rotatably connected to the connecting plate 6012. When the handle 603 is pulled, due to a certain damping between the installation box 601 and the winding rod 602, the connecting plate 6012 will be first driven to slide along the connection hole 6011, compressing the elastic sealing plate 6013. After the connecting plate 6012 moves to the extreme position, continuously pulling the handle 603 can overcome the damping at the rotational connection of the winding rod 602, causing the winding rod 602 to rotate and releasing the reflector 3.

[0027] Wherein, a quick-connection component is installed at the bottom of the installation box 601. The quick-connection component includes a second notch 9 provided at the bottom of the installation box 601. A control bar 902 is slidably installed inside the second notch 9. A plug connector 901 is fixedly installed on the control bar 902. A third spring 903 is fixedly installed between the plug connector 901 and the second notch 9. By pressing the control bar 902, the plug connector 901 can be driven to move. Plugging holes are provided in both the connection block 202 and the slider 203. The installation can be completed by inserting the plug connector 901 into the plugging hole.

[0028] As an implementation, the tension component 7 is installed in one of the installation boxes 601. The tension component 7 includes a cylinder 701 rotatably installed in the installation box 601. A sealing plate 702 is slidably installed inside the cylinder 701. A first spring 721 is fixedly installed between the sealing plate 702 and the cylinder 701. The first spring 721 applies an elastic force to the sealing plate 702. A push rod 703 is fixedly installed on the sealing plate 702. The other end of the push rod 703 is rotatably installed with a second connection seat 704. A guide groove 705 is provided in the installation box 601. The second connection seat 704 is slidably connected to the guide groove 705. When the elastic force of the first spring 721 is released, the second connection seat 704 will be driven to slide along the guide groove 705. A positioning cylinder 706 is fixedly installed on the second connection seat 704. A plugging plate 707 is slidably installed inside the positioning cylinder 706. A positioning rod 708 is fixedly installed on the plugging plate 707. A plurality of clamping grooves 709 are provided at the bottom of the winding rod 602. After the positioning rod 708 is inserted into the clamping groove 709, the moving second connection seat 704 will drive the winding rod 602 to rotate, that is, the elastic force of the first spring 721 will act on the winding rod 602.

[0029] As an implementation manner, the anti-loosening component includes connecting pipes 722 fixedly installed at both ends of the cylinder 701. A valve 710 is fixedly installed on the connecting pipe 722. When there is a hydraulic medium inside the cylinder 701, the hydraulic medium is a liquid that cannot be compressed under the working environment. The movable sealing plate 702 will drive the hydraulic medium on both sides to be extruded. At this time, the hydraulic medium will flow through the connecting pipe 722. When the valve 710 is closed, the sealing plate 702 cannot move. At this time, the first spring 721 cannot push the sealing plate 702 to move, that is, the elastic force of the first spring 721 cannot be released at this time.

[0030] Among them, the valve 710 includes a valve body 7101. A valve core 7102 is rotatably installed inside the valve body 7101. A first connecting shaft 7103 is fixedly installed on the valve core 7102. When the first connecting shaft 7103 is rotated, the valve core 7102 will be driven to rotate, thereby controlling the opening and closing state of the valve body 7101. An anti-loosening cylinder 711 is rotatably installed inside the installation box 601. A sealing piece 712 is slidably installed inside the anti-loosening cylinder 711. An opening and closing rod 713 is fixedly installed on the sealing piece 712. The opening and closing rod 713 is fixedly connected to the first connecting shaft 7103. When the sealing piece 712 drives the opening and closing rod 713 to move, the first connecting shaft 7103 will be driven to rotate through the opening and closing rod 713, thereby controlling the opening and closing state of the valve 710.

[0031] As an implementation manner, two driving cylinders 714 are rotatably installed inside the installation box 601. A sliding piece 715 is slidably installed inside the driving cylinder 714. A detection rod 716 is fixedly installed on the sliding piece 715. The other end of the detection rod 716 is rotatably connected to the connecting plate 6012. When the reflector 3 is stretched, since the connecting plate 6012 will be driven to slide along the connecting hole 6011 first, when the reflector 3 is stretched, the detection rod 716 will be driven to move by the connecting plate 6012 first, so that the detection rod 716 drives the sliding piece 715 to slide. Two conveying pipes 717 are fixedly installed at both ends of the driving cylinder 714. The two conveying pipes 717 on one driving cylinder 714 are communicated with both ends of the positioning cylinder 706, and the two conveying pipes 717 on the other driving cylinder 714 are communicated with both ends of the anti-loosening cylinder 711. Since the positioning cylinder 706, the anti-loosening cylinder 711, the connecting pipe 722, the driving cylinder 714 and the conveying pipe 717 are all filled with a hydraulic medium, the two moving sliding pieces 715 will convey the hydraulic medium into the anti-loosening cylinder 711 and the positioning cylinder 706, thereby synchronously driving the positioning rod 708 to move downward, so that the positioning rod 708 disengages from the clamping groove 709. At the same time, the moving sealing piece 712 blocks the valve 710, so that the first spring 721 cannot be released. At this time, if the reflector 3 is stretched continuously, the reflector 3 will not be affected by the elastic force and will not affect the first spring 721.

[0032] It should be noted that an indicating needle 719 is fixedly installed on the cylinder 701 through a second connecting shaft 718. The indicating needle 719 is coaxially positioned with the rotational connection between the cylinder 701 and the mounting box 601. Scale lines 720 are provided on the mounting box 601. After the stretching of the reflector 3 is completed, under the action of the sealing plate 6013, the connecting plate 6012 will be reset, thereby resetting the sliding piece 715. At this time, the positioning rod 708 will be inserted into the clamping groove 709 again, and the valve 710 will be opened, so that the elastic force of the first spring 721 acts on the reflector 3, making the reflector 3 in a tensioned state.

[0033] Due to the possible misalignment between the positioning rod 708 and the clamping groove 709, a material piece that can undergo axial elastic deformation can be added to the end of the positioning rod 708, which enables the end of the positioning rod 708 to be compressed. When not combined with the clamping groove 709, under the elastic force of the first spring 721, the positioning rod 708 undergoes a certain amount of slippage, and the positioning rod 708 can enter the clamping groove 709. This will cause the elastic force of the first spring 721 to be gradually released, resulting in the inability to effectively apply a tensioning force to the reflector 3.

[0034] When the elastic force of the first spring 721 is gradually released, it will drive the cylinder 701 to rotate. The rotating cylinder 701 can drive the indicating needle 719 to rotate. The scale line 720 is provided with a safety zone that can effectively apply an elastic force to the reflector 3 and a failure zone that cannot apply an elastic force to the reflector 3. When the indicating needle 719 rotates to the failure zone, by rotating the indicating needle 719, the cylinder 701 can be driven to rotate, and the second connecting seat 704 can be moved, and the first spring 721 can be compressed, thereby re-adjusting the elastic force of the first spring 721.

[0035] In this embodiment, when the reflector 3 is pulled out and bent, the reflector 3 will drive the limiting blocks 401 to move. Two adjacent limiting blocks 401 will abut against each other, and the abutting limiting blocks 401 will limit each other. Multiple limiting blocks 401 can form a ring, and the ring supports the reflector 3. Furthermore, the reflector 3 can maintain a constant curvature, which can effectively improve the directional lighting effect, avoid local depressions or protrusions, and prevent the reflected light from forming bright and dark stripes or light spots, affecting the lighting uniformity.

[0036] When the handle 603 is pulled, due to the certain damping between the installation box 601 and the winding rod 602, the connecting plate 6012 will first slide along the connecting hole 6011, compressing the elastic sealing plate 6013. After the connecting plate 6012 moves to the extreme position, continuing to pull the handle 603 can overcome the damping at the rotating connection of the winding rod 602, causing the winding rod 602 to rotate and releasing the reflector 3. Therefore, when the reflector 3 is stretched, the detection rod 716 will first be driven to move by the connecting plate 6012, and the detection rod 716 will drive the sliding piece 715 to slide. Thus, the two moving sliding pieces 715 will transport the hydraulic medium into the inside of the anti-loosening cylinder 711 and the positioning cylinder 706, and then synchronously drive the positioning rod 708 to move downward, causing the positioning rod 708 to disengage from the clamping groove 709. At the same time, the moving sealing piece 712 blocks the valve 710, preventing the first spring 721 from being released. At this time, if the reflector 3 is continuously stretched, the reflector 3 will not be affected by the elastic force and will not affect the first spring 721.

[0037] Embodiment 2, as Figures 21 to 26 shown, based on Embodiment 1, this embodiment further includes an energy storage module 8. The energy storage module 8 rotates and stores energy as the reflector 3 extends outward. During the energy storage stage, the energy of the energy storage module 8 cannot be transmitted to the reflector 3. The energy storage module 8 includes an energy release mechanism, and the release mechanism controls the energy to be transmitted to the reflector 3 to drive the reflector 3 to wind. Through the energy storage module 8, the reflector 3 can be automatically retracted without manual winding, and it can avoid the elastic force acting on the immovable reflector 3, preventing the reflector 3 from being damaged by a large tensile force. Moreover, the energy storage module 8 is connected to the connecting plate 6012 and can move integrally with the connecting plate 6012.

[0038] As an implementation manner, the energy storage module 8 is fixedly installed inside another installation box 601. The energy storage module 8 includes a worm 801 rotatably installed inside the installation box 601. The worm 801 is coaxially and fixedly connected to the winding rod 602. When the winding rod 602 rotates, the worm 801 will be driven to rotate. A worm wheel 802 meshing with the worm 801 is rotatably installed in the installation box 601. The rotation of the worm 801 can drive the worm wheel 802 to rotate. A first cylindrical gear 803 is coaxially and fixedly installed on the worm wheel 802. The first cylindrical gear 803 will rotate synchronously with the worm wheel 802. A second cylindrical gear 804 meshing with the first cylindrical gear 803 is rotatably installed in the installation box 601. By driving the second cylindrical gear 804 through the first cylindrical gear 803 and changing the transmission ratio, the number of rotation turns of the second cylindrical gear 804 can be made consistent with that of the winding rod 602. A turntable 805 is coaxially and fixedly installed on the second cylindrical gear 804. A connection disk 806 is fixedly installed in the installation box 601. A volute spring 807 is fixedly installed between the connection disk 806 and the turntable 805. When the second cylindrical gear 804 rotates, the turntable 805 will be driven to rotate. The rotating turntable 805 can wind the volute spring 807, thereby increasing the elastic force of the volute spring 807 and storing the elastic force through the volute spring 807.

[0039] Due to the self-locking property between the worm 801 and the worm wheel 802, that is, the worm 801 can drive the worm wheel 802 to rotate, while the worm wheel 802 cannot drive the worm 801 to rotate, the elastic force of the volute spring 807 cannot drive the worm 801 to rotate, thus having no influence on the winding rod 602 and the reflector 3.

[0040] As an implementation manner, the release mechanism includes a first bevel gear 808 fixedly installed on the worm 801, a second bevel gear 809 rotatably installed in the installation box 601 and meshing with the first bevel gear 808, a third bevel gear 810 coaxially and fixedly connected to the second bevel gear 809, a fourth bevel gear 811 rotatably installed in the installation box 601 and meshing with the third bevel gear 810, a fifth bevel gear 812 coaxially and fixedly connected to the fourth bevel gear 811, a sixth bevel gear 813 fixedly installed on the turntable 805 and meshing with the fifth bevel gear 812. When the elastic force of the volute spring 807 is released, the sixth bevel gear 813 will be driven to rotate, and through the transmission of the fifth bevel gear 812, the fourth bevel gear 811, the third bevel gear 810, the second bevel gear 809 and the first bevel gear 808 in sequence, the worm 801 can be driven to rotate.

[0041] It should be noted that: A first connecting member for controlling the connection state between the second cylindrical gear 804 and the sixth bevel gear 813 is provided between the second cylindrical gear 804 and the sixth bevel gear 813. When the first connecting member disconnects the connection between the second cylindrical gear 804 and the sixth bevel gear 813, the elastic force of the scroll spring 807 will not act on the worm gear 802.

[0042] Furthermore, a second connecting member for controlling the connection state between the second bevel gear 809 and the third bevel gear 810 is provided between the second bevel gear 809 and the third bevel gear 810. When the second connecting member connects the second bevel gear 809 and the third bevel gear 810, the elastic force of the scroll spring 807 can be released and released onto the worm 801.

[0043] As an implementation manner, the first connecting member includes a first control cylinder 814 that is highly installed inside the installation box 601. A first plugging block 815 is slidably installed inside the first control cylinder 814. A first control rod 816 is fixedly installed on the first plugging block 815. A first substrate 817 is fixedly installed on the first control rod 816. A first friction plate 818 is rotatably installed on the first substrate 817. A first telescopic rod 819 is fixedly installed on the first friction plate 818. The other end of the first telescopic rod 819 is fixedly connected to the sixth bevel gear 813. A second friction plate 834 is fixedly installed on the second cylindrical gear 804. When the first friction plate 818 contacts the second friction plate 834, the second cylindrical gear 804 will drive the sixth bevel gear 813 to rotate through the second friction plate 834, the first friction plate 818, and the first telescopic rod 819, thereby driving the turntable 805 to rotate. When the first friction plate 818 does not contact the second friction plate 834, the rotating second cylindrical gear 804 will not be able to drive the turntable 805 to rotate.

[0044] Still further, the second connecting member includes a second control cylinder 820 that is highly installed inside the installation box 601. A second plugging block 821 is slidably installed inside the second control cylinder 820. A second control rod 822 is fixedly installed on the second plugging block 821. A second substrate 823 is fixedly installed on the second control rod 822. A third friction plate 824 is rotatably installed on the second substrate 823. A second telescopic rod 826 is fixedly installed on the third friction plate 824. The other end of the second telescopic rod 826 is fixedly connected to the third bevel gear 810. A fourth friction plate 825 is fixedly installed on the second bevel gear 809. When the third friction plate 824 and the fourth friction plate 825 contact, the third bevel gear 810 will drive the second bevel gear 809 to rotate. Otherwise, there will be no transmission between the third bevel gear 810 and the second bevel gear 809.

[0045] In this embodiment, a pressure rod 827 is slidably installed in the installation box 601. The pressure rod 827 penetrates through one side of the installation box 601 and extends to the outside of the installation box 601. A second spring 828 is fixedly installed between the pressure rod 827 and the installation box 601. A synchronization plate 829 is fixedly installed on the pressure rod 827. Two transmission rods 830 are fixedly installed on the synchronization plate 829. A sealing member 831 is fixedly installed on the transmission rod 830. Two transmission cylinders 832 are fixedly installed in the installation box 601. Transport pipes 833 are fixedly installed at both ends of the transmission cylinder 832. The two transport pipes 833 on one of the transmission cylinders 832 are fixedly connected to both ends of the first control cylinder 814. The two transport pipes 833 on the other transmission cylinder 832 are fixedly connected to both ends of the second control cylinder 820. When the pressure rod 827 is pressed, the transmission rod 830 will be driven to move, and then the two sealing members 831 will be driven to move. Since the first control cylinder 814, the second control cylinder 820, the transmission cylinder 832, and the transport pipes 833 are all filled with a hydraulic medium, the first sealing block 815 and the second sealing block 821 can be driven to move through the transmission of the hydraulic medium, so that the third friction plate 824 and the first friction plate 818 can be driven to move mechanically. And because the directions of the transport pipes 833 on the first control cylinder 814 and the second control cylinder 820 are opposite, the moving directions of the third friction plate 824 and the first friction plate 818 are opposite. That is, when the third friction plate 824 contacts the fourth friction plate 825, the first friction plate 818 cannot contact the second friction plate 834. Therefore, by pressing the pressure rod 827, the elastic force of the scroll spring 807 can be released to drive the winding rod 602 to rotate, and then the reflector 3 can be automatically wound.

[0046] Embodiment 3, as Figures 4 to 7 shown, based on Embodiment 1 and Embodiment 2, the curvature control component includes a first connection head 402 fixedly installed at one end of the limit block 401 and a second connection head 403 fixedly installed at the other end of the limit block 401. The adjacent first connection head 402 and the second connection head 403 are rotationally connected. By the rotational connection between the first connection head 402 and the second connection head 403, the adjacent two limit blocks 401 can be rotated along the fixed axis, which can enhance the structural strength of the multiple limit blocks 401.

[0047] Furthermore, the curvature control component includes a plurality of positioning blocks 404. A connection groove 405 is provided on the positioning block 404. The positioning block 404 is made by evenly cutting a ring. A connection rope 406 is fixedly installed in the connection groove 405. Contact surfaces 407 are provided at both ends of the positioning block 404. Notches 408 are provided on both sides of the connection groove 405. The rotational connection structure of the above-mentioned first connection head 402 and the second connection head 403 can be replaced by the connection rope 406, which can effectively reduce the processing difficulty of the curvature control component, and the adjacent two contact surfaces 407 will limit each other after contacting each other.
