Technical Field
[0001] This invention relates to the field of LED lighting technology, specifically a split-type four-petal lamp. Background Technology
[0002] In the field of lighting equipment, panoramic mobile lighting, as an important portable lighting tool, is widely used in various scenarios such as outdoor operations, engineering construction, and emergency repairs. Traditional panoramic mobile lighting typically uses halogen lamps or high-intensity discharge lamps as light sources, and their power supply often relies on fixed power sources; some remote-controlled searchlights are relatively large and heavy in order to achieve specific lighting functions. With the development of technology, lighting equipment using LEDs as light sources has gradually emerged. These light sources have the characteristics of high energy efficiency and long lifespan, bringing new possibilities for improving the performance of lighting equipment. However, further optimization is still needed in practical applications to better adapt to the needs of diverse scenarios.
[0003] Existing lighting equipment still has the following shortcomings in performance and structure: the lighting modes are relatively simple, making it difficult to switch flexibly between wide-angle illumination of flat space and 360° circular projection covering the surrounding walls through the adjustment of lamp body components, and it cannot accurately adapt to diverse lighting scenarios; the power supply system design is not perfect, the battery life is limited, and some devices are prone to interruption of lighting when changing batteries; some products lack a balance in structural stability, resistance to accidental tipping and portability, which affects the user experience in complex environments.
[0004] To address this, we developed a new type of split-type four-petal lamp. Summary of the Invention
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a split four-petal lamp, which solves the problems of existing LED lighting lamps having a single lighting mode, difficulty in flexibly switching between wide-angle illumination of the ground and 360° circular projection coverage through lamp body component adjustment, and imperfect power supply system design, limited battery life, and the possibility of interrupting device operation when replacing batteries.
[0006] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: a split four-petal lamp, comprising a main support and a power system, wherein a lighting component is installed on the top of the main support and an auxiliary support component is installed on the periphery of the main support; The lighting assembly includes a top cover fixedly installed on the top of the main support. The top cover has a plurality of first threaded sleeves arranged in a circular array on its circumferential side. A screw is threaded inside the first threaded sleeve. A second threaded sleeve is threaded at the end of the screw away from the first threaded sleeve. An arc-shaped lamp petal is rotatably fitted at one end of the second threaded sleeve. There are four arc-shaped lamp petals. A sliding cover is slidably fitted on the circumferential side of the main support. The bottom of the arc-shaped lamp petal is rotatably connected to the top of the sliding cover.
[0007] Preferably, a fixing clip is fitted around the periphery of the main support, and the fixing clip is located below the sliding cover.
[0008] Preferably, the auxiliary support component includes a connecting sleeve that slides on the circumferential side of the main support, and the bottom of the connecting sleeve is rotatably fitted with several legs in a circumferential array.
[0009] Preferably, the connecting sleeve has an embedding groove on each of its two outer sides, and a lever is rotatably fitted on each of its two outer sides. The lever is embedded in the embedding groove, and a pin is fixedly connected to one side of the lever.
[0010] Preferably, the connecting sleeve has through holes on both of its outer sides, and the through holes are connected to the embedding groove.
[0011] Preferably, the main support has two positioning holes on each of its two outer sides, and the pin passes through the through hole and is inserted into one of the positioning holes.
[0012] Preferably, the power system includes a battery compartment, a power switching module, a main control module, a load output module, and a status monitoring module. Two lithium battery packs are detachably installed in the battery compartment, and both lithium battery packs can be powered independently.

[0014] Preferably, the main support frame adopts a telescopic structure.
[0015] (III) Beneficial Effects This invention provides a split-type four-petal lamp, which has the following beneficial effects: 1. This split-type four-petal lamp, through the synchronous expansion and contraction of the arc-shaped lamp petals in the lighting component, can flexibly switch between wide-angle illumination of flat space and 360° circular projection covering the surrounding wall area, accurately adapting to diverse lighting scenarios and solving the problem of the single mode of traditional lighting equipment.
[0016] 2. This split-type four-petal light uses a dual-lithium battery pack independent power supply design. With the help of a power switching module and a main control module, it can automatically switch to the other battery when one battery is low on power. During the switching process, the capacitor stores energy to maintain voltage stability, ensuring uninterrupted lighting. Users can replace the dead battery at the same time, which greatly extends the continuous use time of the device and improves the reliability of the battery life.
[0017] 3. This split-type four-petal lamp forms a stable support by controlling the unfolding of the support legs and the positioning of the connecting sleeve, adapting to different ground environments; and the main support adopts a telescopic structure, which can flexibly adjust the overall height to meet different lighting height requirements.
[0018] 4. This split-type four-petal lamp can drive the arc-shaped lamp petals to rotate upward by adjusting the matching relationship between the sliding cover and the hinge joint of the arc-shaped lamp petals (switching the connection between the top hinge joint of the lamp petals and the sliding cover). This breaks the limitation of only being able to illuminate downwards and can accurately cover the space above (such as suspended ceilings, high-altitude pipes, etc.), further expanding the lighting coverage dimension and improving the adaptability to diverse scenarios.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Examples, such as Figure 1 - Figure 6 As shown, this embodiment of the invention provides a split four-petal lamp, a main support 1 and a power system 18. A lighting component 2 is installed on the top of the main support 1, and an auxiliary support component 3 is installed on the sides of the main support 1.
[0023] Specifically, the lighting component 2 includes a top cover 4 fixedly installed on the side of the main support 1. The side of the top cover 4 is rotatably fitted with a number of first threaded sleeves 5 in a circular array. The first threaded sleeves 5 are internally threaded with screws 6. The end of the screws 6 away from the first threaded sleeves 5 is threadedly connected with a second threaded sleeve 7. One end of the second threaded sleeve 7 is rotatably fitted with an arc-shaped lamp petal 8. The connection between the arc-shaped lamp petal 8 and the second threaded sleeve 7 is close to the middle part of the arc-shaped lamp petal 8. There are four arc-shaped lamp petals 8. A sliding cover 9 is slidably fitted on the side of the main support 1. Two hinge joints 22 are fixedly connected to one side of the arc-shaped lamp petal 8. The two hinge joints 22 are respectively close to the top and bottom of the arc-shaped lamp petal 8. The hinge joints 22 are rotatably connected to the top of the sliding cover 9. The top cover 4 provides a fulcrum for the rotation of the first threaded sleeve 5. The first threaded sleeve 5 is fixed to the screw 6 and the second threaded sleeve 7 through threaded connections. The screw 6 connects the top cover 4 to the arc-shaped lamp petal 8, while the second threaded sleeve 7 rotates with the arc-shaped lamp petal 8, providing a fulcrum for the rotation of the lamp petal. When the hinge joint 22 near the bottom of the arc-shaped lamp petal 8 is hinged to the sliding cover 9, the sliding cover 9 moves up and down in the vertical direction. The sliding cover 9 applies a force to the bottom of the arc-shaped lamp petal 8. Under the constraint of the screw 6, the arc-shaped lamp petal 8 rotates with the connection point of the second threaded sleeve 7 as the fulcrum. At the same time, the screw 6 rotates with the connection point of the first threaded sleeve 5 as the fulcrum, realizing the synchronous counterclockwise expansion or clockwise contraction of the arc-shaped lamp petal 8, thereby changing the lamp's rotation. The angle of downward illumination; when the hinge joint 22 at the bottom of the arc-shaped lamp petal 8 is disconnected from the sliding cover 9, the positioning bolt on the top cover 4 is released and the top cover 4 is moved down, so that the screw 6 is flipped to a position symmetrical to its original position. Then, a new sliding cover 9 is installed above the top cover 4, and the hinge joint 22 near the top of the arc-shaped lamp petal 8 is hinged to the new sliding cover 9. Then, the new sliding cover 9 is moved up and down in the vertical direction. The sliding cover 9 applies a force to the top of the arc-shaped lamp petal 8. Under the constraint of the screw 6, the arc-shaped lamp petal 8 rotates with the second threaded sleeve 7 as the fulcrum, and at the same time, the screw 6 rotates with the first threaded sleeve 5 as the fulcrum, so as to realize the synchronous clockwise expansion or counterclockwise contraction of the arc-shaped lamp petal 8, thereby changing the angle of upward illumination of the light.
[0024] A fixing clip 10 is fitted around the side of the main support frame 1. The fixing clip 10 is located below the sliding cover 9 and is securely fitted onto the main support frame 1 by the locking force of bolts and nuts. Its core function is to form a lower limit for the sliding cover 9. When the vertical height of the sliding cover 9 on the main support frame 1 is adjusted, the fixing clip 10 is installed below the sliding cover 9 to prevent the sliding cover 9 from moving down.
[0025] Specifically, the auxiliary support component 3 includes a connecting sleeve 11 that slides on the side of the main support 1. The bottom of the connecting sleeve 11 is rotatably fitted with several legs 12 in a circular array. The connecting sleeve 11 can slide along the main support 1 to adjust the height of the legs 12. The legs 12 can rotate relative to the connecting sleeve 11 and, after unfolding, contact the ground to form support, thereby improving the stability of the lamp placement.
[0026] The connecting sleeve 11 has an embedding groove 13 on each of its two outer sides. The connecting sleeve 11 has a lever 14 rotatably fitted on each of its two outer sides. The lever 14 is embedded in the embedding groove 13. A pin 15 is fixedly connected to one side of the lever 14. The connecting sleeve 11 has a through hole 16 on each of its two outer sides. The through hole 16 communicates with the embedding groove 13. The main support 1 has two positioning holes 17 on each of its two outer sides. The pin 15 passes through the through hole 16 and is inserted into one of the positioning holes 17. The embedded groove 13 is used to house the lever 14, reducing space occupation. When the lever 14 rotates, it drives the pin 15 to move. When the lever 14 is embedded in the embedded groove 13, the pin 15 will pass through the through hole 16 and be inserted into the corresponding positioning hole 17, thereby fixing the vertical height of the connecting sleeve 11 on the main body bracket 1. When it is disengaged, the pin 15 moves out of the positioning hole 17, and the connecting sleeve 11 can be moved up and down to adjust its vertical height on the main body bracket 1.
[0027] Specifically, the power system 18 includes a battery compartment, a power switching module, a main control module, a load output module, and a status monitoring module. Two lithium battery packs are detachably installed in the battery compartment. Both lithium battery packs can be powered independently, so when one lithium battery pack is depleted and needs to be replaced, the other lithium battery pack can replace it to provide power. The battery compartment has two interface modules, each corresponding to one of the two detachable lithium battery packs. Each interface is equipped with an independent overcharge protection circuit, which includes a fuse and a Zener diode. Each interface also has reverse polarity protection terminals. The two battery compartment interfaces are connected in parallel to a power switching module via wires. The power switching module has a built-in switching circuit, driven by a control signal output from the main control module, to automatically switch battery paths. The main control module is controlled by a microcontroller and collects the output voltage of the two batteries in real time through a voltage detection circuit, which is a series voltage divider resistor network. When the main control module detects that the voltage of one battery is lower than a preset threshold, it sends a signal to the power switching module. The switching signal disconnects the current battery path and connects the other battery path, and during the switching process, the load terminal voltage is kept stable through the capacitor energy storage circuit; the load output module includes a step-down circuit and a current limiting circuit. The output voltage of the step-down circuit is adapted to the working voltage of the LED lamp group, and is used to convert the battery output voltage into a stable working voltage to supply the LED light source of the lamp head and lamp petals in the lighting component 2. The current limiting circuit is used to limit the maximum output current to protect the LED components; the status monitoring module displays the power status of the two batteries through red and green dual-color LED indicators. When fully charged, the green light is always on, and when low, the red light flashes. The status monitoring module also transmits the power data to the main control module to assist in completing the switching logic judgment. A control box 19 is fixedly installed on the side of the main support frame. A control panel 20 is fixedly installed on the top of the control box 19. A handle 21 is fixedly connected to one side of the control box 19. The control panel 20 is used by the user to operate the lamp functions, and the handle 21 is convenient for carrying and moving the lamp, improving the ease of use. The main support 1 adopts a telescopic structure, and its overall height can be changed by adjusting its telescopic length to adapt to the lighting height requirements of different scenarios. When it is necessary to raise the light fixture, the main support 1 is stretched to the target length, and the positioning buckle inside will automatically engage and fix it; if it is necessary to lower the height, the main support 1 can be retracted by pressing the positioning buckle.
[0028] Working principle: When the lamp is moved to the lighting position, the toggle block 14 is first disengaged from the recess 13, thereby causing the toggle block 14 to move the pin 15 out of the upper positioning hole 17. Then the support leg 12 is unfolded and the connecting sleeve 11 is moved downward along the main support 1 to adjust the height of the support leg 12. When the end of the support leg 12 contacts the ground, it will form a stable support. Finally, the toggle block 14 is re-embedded into the recess 13 to drive the pin 15 into the lower positioning hole 17, thereby fixing the position of the connecting sleeve 11. When the lighting angle of this lamp needs to be adjusted, if the hinge joint 22 at the bottom of the arc-shaped lamp petal 8 is hinged to the sliding cover 9 located below, the sliding cover 9 located below can be moved vertically along the main support 1 to apply force to the bottom of the arc-shaped lamp petal 8. Under the constraint of the screw 6, the arc-shaped lamp petal 8 rotates with the connection of the second threaded sleeve 7 as the fulcrum, while the screw 6 rotates with the connection of the first threaded sleeve 5 as the fulcrum, so that the four arc-shaped lamp petals 8 simultaneously expand counterclockwise or contract clockwise to change the angle of downward illumination; the fixing clamp 10 is locked to the main support by bolts and nuts. On the frame 1, a lower limit position is formed below the sliding cover 9 to prevent the sliding cover 9 from moving down and fix the opening and closing state of the lamp petal; if the hinge joint 22 near the top of the arc-shaped lamp petal 8 is hinged to the upper sliding cover 9, and then the upper sliding cover 9 is moved in the vertical direction, the sliding cover 9 applies a force to the top of the arc-shaped lamp petal 8. Under the constraint of the screw 6, the arc-shaped lamp petal 8 rotates with the second threaded sleeve 7 as the fulcrum, and at the same time the screw 6 rotates with the first threaded sleeve 5 as the fulcrum, so as to realize the synchronous clockwise expansion or counterclockwise contraction of the arc-shaped lamp petal 8 to change the angle of the light shining upward.
