[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To address the problems of limited lighting range, inflexible adjustment, and limited functionality in existing technologies, this utility model provides a multi-head adjustable lighting device. Please refer to... Figures 1-6 , Figure 1 This is a schematic diagram of the multi-head adjustable lighting device in the open state provided in this embodiment of the utility model; Figure 2 This is a structural schematic diagram of the multi-head adjustable lighting device in its retracted state according to an embodiment of this utility model; Figure 3 This is a schematic diagram of the mechanism of the light effect adjustment accessory in the retracted state according to an embodiment of the present utility model;
[0027] Figure 4 This is a schematic diagram of the structure of the rotating head provided in an embodiment of the present invention; Figure 5 This is a schematic diagram of the structure of the pivot block provided in an embodiment of the present invention; Figure 6 This is a schematic diagram of the bottom surface of the base provided in an embodiment of this utility model.
[0028] like Figure 1-2As shown, the device includes: a base 1, with a power supply component inside the base 1; a lighting component 2, which is rotatably connected to the base 1, and includes at least two lamp heads, with two adjacent lamp heads being rotatably connected; and a light effect adjustment accessory 3, which is detachably connected to the light-emitting surface of the lamp head.
[0029] The base 1 serves as the support structure for the device and contains a power supply component that can power the entire lighting device. This device is independently powered, making it portable and flexible in use.
[0030] The lighting component 2 is rotatably connected to the base 1, meaning that the lighting component 2 can be adjusted in its overall direction. The lighting component 2 includes multiple lamp heads, each of which can be individually adjusted to achieve multi-directional lighting and expand the lighting range. When the lighting component 2 is folded up, the non-light-emitting surfaces of each lamp head fit snugly against the base 1 to reduce overall space occupation and facilitate storage.
[0031] The light effect adjustment accessory 3 is detachably mounted on the light-emitting surface of the lamp head. Depending on actual needs, it can be selected whether or not to install this accessory to achieve the desired lighting effect. When light effect adjustment is not required, the light effect adjustment accessory 3 can be quickly detached to restore the original lighting effect.
[0032] As an optional implementation, the lighting assembly 2 includes a first lamp head 201, a second lamp head 202, and a third lamp head 203; the first lamp head 201 is rotatably connected to the base 1; the second lamp head 202 and the third lamp head 203 are located on both sides of the first lamp head 201 and are rotatably connected to the first lamp head 201.
[0033] On either side of the first lamp head 201, a second lamp head 202 and a third lamp head 203 are symmetrically arranged, and the second lamp head 202 and the third lamp head 203 are connected to the first lamp head 201 by a rotatable connection. This structure allows the three lamp heads to not only provide coordinated illumination on the same plane, but also to adjust their angles independently. For example, when wide-area illumination is required, the user can open the second lamp heads 202 and the third lamp heads 203 on either side of the first lamp head 201 to the left and right at a certain angle to achieve wide-area illumination; alternatively, the three lamp heads can be oriented in the same direction to enhance local illumination intensity.
[0034] In addition, the three lamp heads are controlled by independent control circuits, so that each lamp head can achieve independent lighting. That is, the first lamp head 201, the second lamp head 202 and the third lamp head 203 can be lit at the same time, or one of the lamp heads can be lit alone. Alternatively, two of the lamp heads can be lit at the same time.
[0035] As an optional implementation method, such as Figure 4As shown, the first lamp head 201 is connected to the top surface of the base 1 via a rotating head 5; the rotating head 5 includes a first pivot 501, a second pivot 502 and a third pivot 503; the first pivot 501 and the second pivot 502 are arranged opposite to each other, and the line connecting the axes of the first pivot 501 and the second pivot 502 is perpendicular to the axis of the third pivot 503; the first pivot 501 and the second pivot 502 are respectively inserted into the first lamp head 201 and rotatably connected to the first lamp head 201, and the third pivot 503 is inserted into the base 1 and rotatably connected to the base 1.
[0036] The first lamp head 201 has a mounting groove at one end for connecting to the base 1. A rotating head 5 is installed in the mounting groove to connect the first lamp head 201 and the base 1. The rotating head 5 is a three-way connector, with its first pivot 501 and second pivot 502 positioned opposite each other and passing through protrusions on both sides of the mounting groove to achieve a rotatable connection, meaning the first lamp head 201 can rotate relative to the rotating head 5. The axis connecting the first pivot 501 and the second pivot 502 is a straight line, and the axis of the third pivot 503 is perpendicular to this line. The third pivot 503 passes into a slot in the base 1 and is rotatably connected to the base 1, meaning the rotating head 5 can rotate relative to the base 1. This allows for multi-angle adjustment of the first lamp head 201 relative to the base 1.
[0037] Furthermore, the connecting wire for connecting the base 1 and the lighting device is routed inside the pivot. To prevent cable tangling, a limiting protrusion is provided in the slot of the base 1 to limit the rotation range of the third pivot 503. Preferably, the third pivot 503 rotates 270°.
[0038] Furthermore, each pivot is rotatably connected via components such as spring washers, flat washers, and nuts.
[0039] As an optional implementation method, such as Figure 5 As shown, the first lamp head 201 has pivot grooves on both sides; the second lamp head 202 and the third lamp head 203 are respectively provided with pivot blocks 6, each pivot block 6 is located in the pivot groove on the corresponding side and is rotatably connected to both ends of the pivot groove.
[0040] The first lamp head 201 has pivot grooves on both sides. Each pivot groove is rotatably connected to the pivot block 6 of the lamp head on that side. The pivot block 6 has a rotating shaft 601 at both ends. Each rotating shaft 601 passes through the side end of the pivot groove. One end of the connector 604 is sleeved on the outside of the rotating shaft 601. The other end of the connector 604 is fixed inside the side end of the pivot groove. The connector 604 forms a damped rotation structure through components such as spring washer 603, flat washer 605 and nut 602.
[0041] As an optional implementation, the light effect adjustment accessory 3 is a diffuser.
[0042] A diffuser is a common optical accessory, usually made of translucent material. Its main function is to diffuse the strong light emitted by the lamp head, thereby reducing the sharpness of the light and creating a more uniform and softer lighting effect.
[0043] Furthermore, the diffuser is detachable, allowing for flexible installation or removal as needed. For example, it can be removed for situations requiring strong, long-range light, resulting in more focused and brighter illumination; while it can be installed indoors or for close-range use to achieve a balance between soft lighting and eye comfort.
[0044] Furthermore, the lamp head is equipped with a mounting slot for a diffuser, which can be magnetically attached to the slot. Each lamp head corresponds to one diffuser, allowing all lamp heads to be fitted with diffusers simultaneously to achieve a wider range of floodlight effects.
[0045] As an optional implementation method, such as Figure 3 As shown, the base 1 has a card slot for accommodating the light effect adjustment accessory 3 after it is installed; the card slot is equipped with a magnetic component for adsorbing the light effect adjustment accessory 3.
[0046] A accommodating slot is provided on the base 1 for storing and securing the light effect adjustment accessory 3 (such as a diffuser) when not in use. When the lighting component 2 is retracted, it can cover the accommodating slot. This structure not only prevents the accessories from being randomly placed or lost when not in use, but also makes the entire lighting device neater and more compact during transportation or carrying, improving the product's portability and integration. It should be noted that the number of light effect adjustment accessories 3 corresponds to the lamp head, and the depth of the accommodating slot should be sufficient to accommodate all the light effect adjustment accessories 3.
[0047] To further enhance the stability of the accessories, a magnetic closure is installed inside the slot to attract the magnetic or metal parts on the light effect adjustment accessory 3. Compared with traditional snap-on or threaded connections, this magnetic structure offers advantages such as ease of operation, reliable adhesion, and quick assembly / disassembly. Users can easily store or retrieve the accessories with a simple placement, improving efficiency.
[0048] As an optional implementation method, such as Figure 6 As shown, the bottom surface of the base 1 is provided with a magnetic suction element 9.
[0049] The base 1 integrates a magnetic element 9, preferably three magnets, which allows the lighting device to be quickly and firmly attached to metal surfaces, such as vehicle bodies, machinery, metal structures, or electrical boxes, without the need for additional support or tools. This structure makes the device more stable and reliable during use, and is particularly suitable for emergency lighting in outdoor operations, maintenance work, or confined spaces, significantly improving the stability of the lighting and the flexibility of operation.
[0050] As an optional implementation, the base 1 has an internal cavity containing a control motherboard and a battery assembly; a battery cover is detachably connected to the top surface of the base 1 to seal the cavity; a waterproof ring is provided at the contact point between the battery cover and the base 1.
[0051] The base 1 has an internal cavity for mounting the control motherboard and battery assembly, centrally encapsulating the core control and power supply units of the entire lighting system, thus improving the device's compactness and integration. The control motherboard, a PCB board, is responsible for controlling functions such as lighting modes and power management, while the battery assembly provides rechargeable or replaceable power support for the lighting device, ensuring independent operation even in environments without external power, making it suitable for outdoor and emergency scenarios.
[0052] The top surface of the base 1 is detachably connected to the battery cover, preferably using screws, which facilitates battery replacement or system maintenance, improving the maintainability and extending the lifespan of the device. A waterproof ring is placed at the contact point between the battery cover and the base 1, further enhancing the device's sealing performance and effectively preventing rainwater, dust, or moisture from entering the internal electronic component area, ensuring safe operation of the device in outdoor or humid environments.
[0053] In addition, the area above the battery cover is a slot for storing light effect adjustment accessories 3, such as a diffuser, to further integrate the structure and function and optimize space.
[0054] As an optional implementation, the bottom surface of the base 1 is provided with an anti-slip pad 11; the bottom surface of the base 1 is provided with a hook 10.
[0055] An anti-slip pad 11 is located on the bottom surface of the base 1 to increase the friction between the device and the contact surface, preventing the device from sliding or tipping over on smooth or inclined surfaces, thereby improving safety and stability during use. It is particularly suitable for use on flat surfaces such as desktops, floors, or mechanical platforms. The anti-slip pad 11 also has a certain cushioning effect, reducing the impact of vibration on internal components during transportation and extending the service life of the device. Preferably, the anti-slip pad 11 is made of rubber.
[0056] In addition, the hook 10 provides the option of hanging the device, allowing users to hang the lighting device on the wall, tool rack, tent pole, etc., as needed on site, to achieve high-level lighting or directional lighting, expanding the usage and enhancing application flexibility.
[0057] As an optional implementation, the base 1 has a charging port 4, control buttons 7 and a display screen 8 on its side.
[0058] Charging port 4 is used to replenish the built-in battery assembly and supports charging via an external power adapter or power bank, ensuring that the device can be used again promptly after the battery is depleted, thus enhancing its battery life and adaptability to field operations. Located on the side of the base 1, it allows users to easily plug and unplug the charging cable without disassembling other components, improving maintenance efficiency.
[0059] Control button 7 is used to operate and control various functions of the lighting device, such as turning the lights on and off, adjusting brightness, and switching lighting modes, helping users flexibly adjust the usage status according to actual needs. The button design is concentrated on the side, with an intuitive layout, good operating feel, and ergonomic design, making it easy to operate with one hand. In addition, a microwave radar sensor is also provided to detect dynamic targets in the surrounding environment (such as people, vehicles, etc.) and trigger corresponding lighting responses. For example, when the sensor detects someone approaching, the lighting device can automatically turn on; if there is no detection signal for a period of time, the lighting will automatically turn off, thereby realizing intelligent sensing control, reducing energy consumption, and extending battery life.
[0060] Display screen 8 is used to display the device's working status information in real time, such as current battery level, lighting level, mode indication, etc., so that users can intuitively grasp the device's operating status and improve the interactive experience and safety of use.
[0061] The above technical solution has the following beneficial effects: the rotatable connection between multiple lamp heads enables flexible adjustment of the lighting direction to adapt to different usage environments, and the multiple lamp heads illuminate in different directions, thereby increasing the lighting range; by setting a detachable light effect adjustment accessory on the light-emitting surface of the lamp head, the illumination effect can be adjusted, thereby improving the versatility of functions.
