Detailed Implementation
[0022] 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.
[0023] To address the problems of limited lighting range and poor waterproof performance in existing lighting equipment, this utility model provides a lighting device, including: a handle 2 and a lamp head 1, the lamp head 1 being rotatably connected to the handle 2; a first light source 3 and a second light source 4 are respectively provided on both sides of the lamp head 1, and a third light source 5 is provided at the free end of the lamp head 1; the first light source 3, the second light source 4 and the third light source 5 are respectively sealed inside the housing of the lamp head 1 by sealing elements 7; and a sensor switch, the sensor switch being used to control the closing of the first light source 3 and / or the second light source 4 and / or the third light source 5.
[0024] The handle 2 and the lamp head 1 are connected via a rotating head to achieve a rotatable connection. This rotating head may include a pin, sleeve, elastic washer, and limiting washer, used to provide appropriate damping torque while ensuring smooth rotation, so that the lamp head 1 remains stable after being adjusted to the target angle. The rotation angle can cover a range from the closed state to the working state, for example, 0° to 180°. To ensure reliable electrical connection, bending allowance and wiring grooves are provided in the rotating shaft accessory to prevent wire breakage due to tension during rotation.
[0025] The housing of lamp head 1 forms an internal cavity for mounting the first light source 3, the second light source 4, and the third light source 5. The first light source 3 and the second light source 4 are located on opposite sides of lamp head 1, with their light emission directions opposite to each other, so as to achieve illumination of two lateral areas, either left and right or up and down; the third light source 5 is arranged at the free end of lamp head 1, with its light emission direction consistent with the axis of lamp head 1, for frontal illumination.
[0026] The three light sources can be in the form of LED light panels: the light panels are fixed to the corresponding mounting surfaces inside the housing, with the light-emitting surface of the light panel facing the corresponding light outlet. A heat-conducting contact surface is provided on the back of the light panel to facilitate contact with the corresponding mounting platform inside the housing and to transfer working heat. In this embodiment, the light-emitting surface of the first light source 3 faces the handle 2 when the lamp body is closed, and the second light source 4 has the opposite light-emitting direction.
[0027] The light-emitting ports of the first light source 3 and the second light source 4 are respectively equipped with light-transmitting elements, and a sealing element is sandwiched between the light-transmitting element and the housing to achieve a seal. The sealing element can be an annular or strip-shaped sealing strip, which is continuously arranged along the edge of the light-transmitting element; the light-transmitting element is subjected to uniform pressure in the circumferential direction by the clamping structure on the housing (such as a baffle, pressure frame or screw plate), so that the sealing strip is compressed to a predetermined compression amount, thereby forming a reliable waterproof seal throughout the circumference.
[0028] The third light source 5 is located at the free end of the lamp head 1, and its light outlet is equipped with an end-transmitting element. The light-transmitting element axially compresses the annular sealing ring to achieve a seal. To prevent uneven sealing caused by assembly deviations, an annular step and a groove for mating with the sealing ring can be designed on the end face of the housing to guide and limit the sealing ring. The sealing material can be an elastomer (such as silicone rubber, fluororubber, or EPDM), and the light-transmitting element can be a high-transmittance material (such as PC, PMMA, or tempered glass) to balance optical transmittance and environmental resistance.
[0029] A motion-sensor switch is used to automatically turn off one or more light sources under predetermined conditions to reduce accidental activation and standby power consumption. The motion-sensor switch includes a sensing unit for detecting relative position / state and a control unit electrically connected to it. The sensing unit is installed at the corresponding position of the handle 2 and the lamp head 1, and can output a valid signal when the lamp head 1 is rotated to a preset closed area or approaches the handle 2. The control unit is connected to the drive circuits of the first light source 3, the second light source 4, or the third light source 5, respectively. When the sensing signal is valid, the control unit outputs a shutdown command, which can control the shutdown of the first light source 3 and / or the second light source 4 and / or the third light source 5. When the sensing signal is released (e.g., the lamp head 1 is rotated out of the closed position), the control unit restores the light source to an operable state (e.g., allowing it to be re-activated via manual button press or predetermined logic).
[0030] As an optional implementation, the inductive switch includes an inductive magnet 6 and a Hall control switch; the lamp head 1 is provided with an inductive magnet 6, and the handle 2 is provided with a Hall control switch. When the lamp head 1 is close to the handle 2, the Hall switch controls the corresponding light source to turn off.
[0031] A sensing magnet 6 is installed at a predetermined position on the lamp head 1. A Hall effect control switch is installed inside the handle 2 in the area corresponding to the sensing magnet 6, and the Hall effect control switch can be located on the control main board. When the user rotates the lamp head 1 to a position close to the handle 2, the sensing magnet 6 enters the sensing range of the Hall effect control switch. The Hall effect control switch detects the magnetic field signal and outputs a trigger signal to the control main board 21. Upon receiving the trigger signal, the control main board 21 automatically executes a shutdown command, turning off the first light source 3, the second light source 4, and / or the third light source 5, thereby preventing the device from continuing to consume power when not in operation.
[0032] Preferably, in this embodiment, only the first light source 3 that emits light towards the handle 2 when the handle is closed is controlled by a sensor switch to avoid the handle getting hot due to prolonged exposure of the light source to the handle when the handle is closed.
[0033] As an optional implementation, the lamp holder 1 includes a first mounting shell 10 and a second mounting shell 11; a first light source 3 and a second light source 4 are disposed in the cavity of the first mounting shell 10, and the light-emitting surfaces of the first light source 3 and the second light source 4 are opposite in direction; a third light source 5 is disposed in the cavity of the second mounting shell 11, and the light-emitting surface of the third light source 5 faces the outside of the free end of the lamp body.
[0034] The internal cavity of the first mounting housing 10 is used to install the first light source 3 and the second light source 4, which are arranged along opposite sides of the housing and have opposite light-emitting directions. This arrangement allows for separate illumination of both sides of the lamp head 1, enabling the device to obtain dual-sided lighting effects simultaneously during use, which is suitable for work scenarios that require simultaneous attention in both left-right or up-down directions.
[0035] The internal cavity of the second mounting housing 11 is used to install the third light source 5. The light-emitting surface of the third light source 5 faces the outer side of the free end of the lamp head 1, that is, it is aligned with the axis of the lamp head 1, and is mainly used for forward illumination. When it is necessary to focus on the front area, the third light source 5 can provide a concentrated and bright illumination effect. The first light source 3, the second light source 4, and the third light source 5 can all be individually switched on and off.
[0036] As an optional implementation, both the first light source 3 and the second light source 4 are lamp panels, and the sealing element is a sealing strip; the first mounting shell 10 includes an internal partition plate and baffles on both sides of the partition plate; the first light source 3 and the second light source 4 are respectively disposed on both sides of the partition plate; the first light source 3 presses the sealing strips on both sides of the light-emitting surface through the light-transmitting plate 8 on its light-emitting side and the baffles on both sides; the second light source 4 presses the sealing strips on both sides of the light-emitting surface through the light-transmitting plate 8 on its light-emitting side and the baffles on both sides.
[0037] Both the first light source 3 and the second light source 4 adopt a lamp board structure, that is, a circuit board is used as a carrier, multiple LED light-emitting elements are arranged on the board surface, and the light is emitted by power supply through a driving circuit.
[0038] To ensure the waterproof performance of the lamp panel mounting area, sealing elements are used, employing sealing strips. These sealing strips are made of elastic waterproof materials (such as silicone rubber, EPDM, etc.) and are continuously arranged around the perimeter of the lamp panel's light outlet. When compressed, the sealing strips create radial and axial seals, preventing external moisture and dust from entering the light source cavity.
[0039] The first mounting housing 10 has a longitudinally extending partition plate inside, dividing the cavity into two independent light source chambers, which respectively accommodate the first light source 3 and the second light source 4. A baffle is provided on each of the two sides of the partition plate, which works in conjunction with the light-transmitting plate 8 to press and seal the sealing strip.
[0040] In specific installation, the first light source 3 is installed on one side of the partition plate, and the light-emitting side is covered by a light-transmitting plate 8. The light-transmitting plate 8 has recessed steps on both sides, which cooperate with the corresponding side baffles to press the ends of the baffles against the steps, improving sealing performance. The baffles and the light-transmitting plate 8 together provide pressure to the sealing strip, achieving multi-directional waterproof sealing. The second light source 4 is installed on the other side of the partition plate, and its sealing element 7 is the same as that of the first light source 3. This allows for ensuring sealing performance even with multiple light sources.
[0041] As an optional implementation, the light-emitting surface of the first light source 3 is provided with a reflector 9; the light-emitting surface of the second light source 4 is provided with a reflector 9.
[0042] Both the first light source 3 and the second light source 4 have reflectors 9 on their light-emitting surfaces. The reflectors 9 are optical elements with high reflectivity. In this embodiment, the light-emitting surface of the first light source 3 has a protrusion in the middle, and reflectors 9 are respectively provided on both sides of the protrusion, which can effectively reflect the light to the light-emitting direction.
[0043] The reflector 9 can be cone-shaped and arranged around the light-emitting surface of the lamp panel, so that the light is reflected to form a more concentrated beam or a more uniform lighting effect, and the light can be transmitted more concentratedly from the light-transmitting plate 8.
[0044] As an optional implementation, the sealing element is a sealing ring; a lens 12 is provided in the second mounting housing 11, and the sealing ring is pressed against the third light source 5 by the lens 12.
[0045] The sealing element of the third light source 5 is a sealing ring. The sealing ring is made of an elastic waterproof material (such as silicone rubber, fluororubber or EPDM, etc.), and has a ring-shaped structure. Its inner diameter matches the outer contour of the third light source 5, and its outer diameter matches the mounting cavity of the second mounting shell 11, so as to form a stable annular seal in the assembled state.
[0046] A lens 12 is installed at the light outlet of the second mounting housing 11. The lens 12 serves both as an optical light distribution component and as a clamping component. During assembly, the sealing ring is fitted around the third light source 5. When the lens 12 is fixed to the second mounting housing 11 by fasteners (such as screws, clamps, or clips), its back side will uniformly compress the sealing ring axially, making the sealing ring tightly fit between the outer peripheral surface of the third light source 5 and the mounting cavity wall, thereby preventing external moisture and dust from entering the cavity where the third light source 5 is located.
[0047] As an optional implementation, the bottom of the handle 2 is provided with a through hole 23 corresponding to the third light source 5. When the lamp head 1 is closed onto the handle 2, the third light source 5 can emit light through the through hole 23.
[0048] Even when the lamp head 1 is closed, the third light source 5 can still provide illumination, which is especially suitable for emergency lighting when the device is stored, fixed, or placed at a special angle. For example, when the lamp head 1 is closed onto the handle 2 for portable storage, the user can still turn on the third light source 5 and obtain outward illumination through the aperture 23, providing simple lighting without having to unfold the lamp head 1.
[0049] The bottom of the handle 2 is also equipped with a rotatable hook 24, which can be used to hang the lighting device for illumination.
[0050] As an optional implementation, an adsorption magnet 13 is provided inside the handle 2 near the bottom; the adsorption magnet 13 is fixed inside the handle 2 by a magnet mounting base 14, and a buffer pad 15 is provided at the bottom of the adsorption magnet 13.
[0051] The magnet 13 is fixed inside the handle 2 by the magnet mounting base 14. The magnet mounting base 14 is made of magnetically conductive metal. The structure of the mounting base can accurately position the magnet 13 and fix it firmly to the inner wall of the handle 2 housing by screws, clips or adhesives, thereby ensuring stable and reliable adsorption force.
[0052] A buffer pad 15 is provided at the bottom of the magnet 13. The buffer pad 15 is made of a flexible material (such as rubber, silicone, or EVA foam) to prevent external impacts on the magnet. During adsorption, magnetic adsorption can be achieved by magnetic conduction through the magnet mounting base 14.
[0053] As an optional implementation, the handle 2 is provided with a charging port 18, and a waterproof cover 19 is provided at the charging port 18.
[0054] The charging port 18 can be selected with different interface forms as needed, such as USB Type-C, Micro-USB or dedicated DC socket, to be compatible with common charging devices or adapters.
[0055] To prevent moisture, dust, and other impurities from entering the handle 2 through the charging port 18 and affecting the operation of electrical components, a waterproof cover 19 is provided on the outside of the charging port 18. The waterproof cover 19 can be made of an elastomer material (such as silicone, TPR thermoplastic rubber, etc.) or a rigid engineering plastic. When closed, the edge of the waterproof cover 19 fits tightly against the sealing ring or limiting groove around the charging port 18, thus forming an effective protective barrier and achieving the corresponding waterproof rating. When charging is needed, the user only needs to lift or unscrew the waterproof cover 19 to connect the charging cable. After charging is complete, the waterproof cover 19 can be reset to maintain a sealed state.
[0056] As an optional implementation, the handle 2 is provided with a battery 16, a battery retainer 17, a control board 21 and a heat sink 22 inside; the battery 16 is pressed into the handle 2 by the battery retainer 17; the battery 16 is electrically connected to the control board 21, and the heat sink 22 is in close contact with one side of the control board 21; the handle 2 is also provided with a control button 20, which is connected to the control board 21.
[0057] As the main power supply unit for the lighting equipment, battery 16 is preferably a rechargeable lithium-ion battery or a lithium polymer battery to achieve higher energy density and cycle life. To prevent battery 16 from shifting during equipment movement or vibration, a battery clamping component 17 is provided inside the handle 2. The battery clamping component 17 can stably press the battery 16 into the battery compartment inside the handle 2 through screws, clips, or elastic structures, thereby avoiding poor contact or internal wear caused by vibration.
[0058] The control board 21 manages power distribution, light source driving, sensor switch signal processing, and control button input. The battery 16 is electrically connected to the control board 21 via wires or soldered terminals to supply power to the various light sources and control circuits. To prevent heat buildup during operation from affecting component lifespan, a heat sink 22 is installed close to one side of the control board 21. The heat sink 22 can be made of a high thermal conductivity metal material (such as aluminum alloy or copper) and forms a heat conduction channel with the inner wall or outer shell of the handle 2 to quickly conduct heat to the external environment.
[0059] The handle 2 is also equipped with control buttons 20, which are connected to the control motherboard 21 via wires or flexible ribbon cables. Users can use the control buttons 20 to control the light source on and off, adjust the brightness, or switch the light source mode. The structure of the control buttons 20 can be customized according to waterproof requirements, such as using silicone-coated button caps or waterproof membrane buttons, to ensure reliability in outdoor or humid environments.
[0060] The above technical solution has the following beneficial effects: the lamp head can be rotatably connected to the handle and a first light source, a second light source, and a third light source are respectively set on both sides and the free end, which can realize multi-directional combined lighting to meet the lighting needs of different work scenarios; since each light source is sealed inside the lamp head housing by a sealing element, it can effectively prevent moisture and dust from entering, improving the reliability and service life of the equipment in harsh environments such as humidity, rain, and snow; since a sensor switch including a sensing magnet and a Hall control switch is set, the corresponding light source can be automatically turned off when the lamp head is close to the handle, avoiding accidental lighting and standby power consumption, and improving ease of use and energy saving.

It should be understood that the above content is only a specific embodiment of the utility model and is not intended to limit the scope of protection of the utility model.
