Description

Technical Field

[0001] This invention relates to the field of industrial and mining lamp water meter technology, and more specifically, to an electromagnetic induction maintenance-free tri-proof industrial and mining lamp. Background Technology

[0002] Industrial and mining lamps, also known as high-bay lamps, are a type of high-efficiency indoor LED lighting fixture that can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, and warehouses. Currently, most industrial and mining lamps are tri-proof, waterproof, insect-proof, and dustproof. However, the wiring of current tri-proof industrial and mining lamps is time-consuming and laborious, and their safety performance is low. Moreover, energy conservation and environmental protection are two major themes of today's social development and an inevitable trend of social development. Electromagnetic induction lamps have emerged to meet this need, and maintenance-free tri-proof industrial and mining lamps using electromagnetic induction are now widely used.

[0003] There are many existing technologies for maintenance-free, tri-proof industrial and mining lamps based on electromagnetic induction, such as:

[0004] According to Chinese patent application number CN03129333.6, an electromagnetic induction lamp structure includes: a lamp head connected to a lamp holder; a housing connected to the lamp head, having an internal cavity; an electromagnetic induction lamp circuit placed within the cavity of the housing; a lamp tube, the inner wall of which is coated with a phosphor layer, and the cavity of the lamp tube containing gas and amalgam; and a coil providing a magnetic field to illuminate the electromagnetic induction lamp. The structure is characterized by a bracket connected to the housing, consisting of two detachable parts forming an internal cavity for placing connecting wires; a magnetic ring bracket connected to the bracket; a magnetic ring placed on the magnetic ring bracket, ring-shaped, fitted onto the lamp tube, with a coil wound around the magnetic ring; the lamp tube forming a closed polygon, the housing located at the center of the closed polygon formed by the lamp tube, and the bracket and magnetic ring bracket located on a straight line passing through the center.

[0005] Although the above-mentioned technology also eliminates the need for circuit and lamp connections and avoids wiring operations, it is inconvenient to control the lamp to turn off when not in use. If the light is focused by the lampshade, it is inconvenient to adjust the focusing range according to the situation. At the same time, when not in use, the lamp head is exposed to the outside world, causing dust to fall on the outer wall of the lamp head and affecting the brightness when in use. In view of this, we propose an electromagnetic induction maintenance-free tri-proof industrial and mining lamp. Summary of the Invention

[0006] The purpose of this invention is to provide an electromagnetic induction maintenance-free tri-proof industrial and mining lamp to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides an electromagnetic induction maintenance-free tri-proof industrial and mining lamp, comprising at least an adjustable lampshade mechanism. An electromagnetic induction mechanism is internally connected to the adjustable lampshade mechanism, and a light bulb is connected to the end of the electromagnetic induction mechanism. When the adjustable lampshade mechanism is in an open state, the electromagnetic induction mechanism generates electromagnetic induction to drive the light bulb to emit light.

[0008] The adjustable lampshade mechanism includes at least a fixed rod, and multiple movable rods are movably connected to the outer wall of the fixed rod, with a shield provided between every two adjacent movable rods;

[0009] The adjusting lampshade mechanism also includes a magnetic ring that slides on the outer wall of the bulb, and the outer wall of the magnetic ring is connected to the movable rods. When the magnetic ring slides into the front end of the bulb, the multiple movable rods are opened by the hinge rods, and at the same time, the electromagnetic induction mechanism is brought close to generate an electromagnetic induction effect to make the bulb light up.

[0010] As a further improvement to this technical solution, the electromagnetic induction mechanism includes at least a connecting rod fixed to the end of the fixed rod, and the outer wall of the connecting rod is provided with two symmetrical support rods, each of which has an arc-shaped magnet at its end.

[0011] The end of the connecting rod is provided with an electrical connecting cover, which is connected and fixed to the light bulb. Copper wire is wound around the outer wall of the electrical connecting cover. The two ends of the copper wire are respectively wound between the two arc-shaped magnets to generate electromagnetic resonance. When the magnetic ring slides to be fitted inside the electrical connecting cover and located between the two arc-shaped magnets, the light bulb generates electromagnetic induction to emit light.

[0012] As a further improvement to this technical solution, an installation assembly is provided between the electrical connection cover and the bulb. The installation assembly includes at least a plug connected to the end of the electrical connection cover, and a sleeve is provided at the end of the bulb. The plug and the sleeve are inserted into each other.

[0013] As a further improvement to this technical solution, the outer wall of the insert is provided with a groove, and an elastic locking block is slidably provided inside the groove. The outer wall of the sleeve is provided with a slot. When the insert rotates inside the sleeve, the elastic locking block is aligned with the slot and engaged.

[0014] As a further improvement to this technical solution, the inner diameter of the magnetic ring is adapted to the outer diameter of the bulb cross-section. When the bulb is turned on by sliding the magnetic ring, the inner wall of the magnetic ring scrapes away the dust on the outer wall of the bulb.

[0015] As a further improvement to this technical solution, the end of the fixed rod is provided with a suspension plate, and the end of the suspension plate is provided with a hanging ring, which is used to suspend the support and adjustment mechanism of the lampshade.

[0016] As a further improvement to this technical solution, the outer wall of the magnetic ring is provided with a linkage control component, wherein:

[0017] The linkage control component includes a pull rope fixed to the outer wall of the magnetic ring. The pull rope moves through the fixed rod and is located outside the shield.

[0018] As a further improvement to this technical solution, the linkage control component also includes a support frame fixed to the outer wall of the suspension plate, the pull rope is located inside the support frame for pulling, and a wheel is rotatably provided at the end of the support frame, the wheel being used to switch the pulling angle of the pull rope from the horizontal direction to the vertical direction.

[0019] As a further improvement to this technical solution, the end of the pull rope is provided with a limiting component, the limiting component including at least a winding frame, and a roller is rotatably provided inside the winding frame, the pull rope being wound around the outer wall of the roller, wherein:

[0020] The end of the roller extends out of the winding frame and is connected to a limiting plate. The surface of the limiting plate has multiple holes at equal intervals. When the limiting plate rotates to a suitable angle, a pin passes through one of the holes to limit and fix the limiting plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this electromagnetic induction maintenance-free tri-proof industrial and mining lamp, multiple movable rods are extended outwards, forming a lampshade-like cover between two movable rods to concentrate the light emitted by the bulb. At the same time, the range of light concentration can be adjusted according to the range of the movable rods, making it convenient to adjust the focusing effect of the bulb's light. In addition, when the multiple movable rods are brought inwards, the bulb can be placed inside the cover for protection, preventing dust from falling onto the bulb when not in use and making it inconvenient to clean.

[0023] 2. In this electromagnetic induction maintenance-free tri-proof industrial and mining lamp, when the magnetic ring slides inward, it brings the magnetic ring closer to the electromagnetic induction mechanism, generating electromagnetic induction to drive the bulb to emit light, allowing the bulb to provide illumination without wiring. On the other hand, the hinge rod opens multiple movable rods, which in turn open the shielding cover to form a lampshade shape, allowing the light from the bulb to shine out from the opening at the bottom of the shielding cover. This lampshade can be used for lighting in industrial plants, production workshops, supermarkets, sports and entertainment venues, and warehouses. At the same time, the multiple shielding covers concentrate the light from the bulb, which is beneficial for lighting the bulb while opening the shielding cover, improving convenience, reducing wiring operations, saving energy and protecting the environment, and avoiding the inconvenience of maintenance in case of circuit problems.

[0024] 3. In this electromagnetic induction maintenance-free tri-proof industrial and mining lamp, pulling the pull rope causes the magnetic ring to move upward, that is, to move inward into the electromagnetic induction mechanism, causing the shield to open and simultaneously driving the bulb to light up. Conversely, after releasing the pull rope, the magnetic ring moves downward along the bulb under its own weight, causing the shield to close and simultaneously turning off the bulb, making it convenient to control the bulb's on and off.

[0039] 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.

[0040] Industrial and mining lamps, also known as high-bay lamps, are high-efficiency indoor LED lighting fixtures widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, and warehouses. Currently, tri-proof industrial and mining lamps are commonly used to achieve waterproof, insect-proof, and dustproof effects. However, current industrial and mining lamps are time-consuming and labor-intensive to wire, and have low safety performance. Furthermore, energy conservation and environmental protection are two major themes of today's social development and an inevitable trend. Electromagnetic induction lamps have emerged to address this need, and maintenance-free tri-proof industrial and mining lamps using electromagnetic induction are now widely used.

[0041] In the existing technology, it is inconvenient to control the lamp to turn off the lighting when it is not in use. If the light is focused by the lampshade, it is inconvenient to adjust the focusing range according to the situation. At the same time, when not in use, the lamp head is exposed to the outside world, which causes dust to fall on the outer wall of the lamp head and affects the brightness when in use.

[0042] Please see Figures 1-8 This invention illustrates a first embodiment of a maintenance-free, three-proof industrial and mining lamp based on electromagnetic induction. The lamp includes at least an adjustable lampshade mechanism 100. An electromagnetic induction mechanism 300 is internally connected to the adjustable lampshade mechanism 100, and a bulb 200 is connected to the end of the electromagnetic induction mechanism 300. When the adjustable lampshade mechanism 100 is in an open state, the electromagnetic induction mechanism 300 generates electromagnetic induction to drive the bulb 200 to emit light.

[0043] The adjustable lampshade mechanism 100 includes at least a fixed rod 110. Multiple movable rods 120 are movably connected to the outer wall of the fixed rod 110. A shield 121 is provided between every two adjacent movable rods 120. By opening the multiple movable rods 120 outward, the shield 121 is placed between the two movable rods 120 to form a lampshade shape, which concentrates the light emitted by the bulb 200. At the same time, the range of light concentration can be adjusted according to the opening range of the movable rods 120, which makes it convenient to adjust the focusing effect of the bulb 200. In addition, when the multiple movable rods 120 are brought together inward, the bulb 200 can be placed inside the shield 121 for protection, so as to prevent dust from falling on the bulb 200 when not in use and making it inconvenient to clean.

[0044] The lampshade adjustment mechanism 100 also includes a magnetic ring 130 that slides on the outer wall of the bulb 200. Multiple hinge rods 122 are movably connected to the outer wall of the magnetic ring 130. When the magnetic ring 130 slides inward toward the front end of the bulb 200, the hinge rods 122 open the multiple movable rods 120, simultaneously generating an electromagnetic induction effect near the electromagnetic induction mechanism 300, causing the bulb 200 to emit light. Thus, when the magnetic ring 130 slides inward, it simultaneously approaches the electromagnetic induction mechanism 300, generating electromagnetic induction to drive the bulb 200 to emit light, allowing the bulb 200 to provide illumination without wiring. On the one hand, the hinge rod 122 opens multiple movable rods 120, and the movable rods 120 drive the shield 121 to open to form a lampshade shape, so that the light of the bulb 200 shines out from the opening at the lower end of the shield 121. It can be used for lighting in industrial plants, production workshops, supermarkets, sports and entertainment venues and warehouses. At the same time, multiple shields 121 concentrate the light of the bulb 200, which is conducive to lighting the bulb 200 while opening the shield 121, improving convenience, reducing wiring operations, saving energy and protecting the environment, and avoiding the inconvenience of maintenance when circuit problems occur.

[0045] Conversely, when the bulb 200 is not in use, the magnetic ring 130 slides outward. On the one hand, the magnetic ring 130 slides out of the electromagnetic induction mechanism 300, stopping the generation of electromagnetic induction effect, which means turning off the illumination of the bulb 200. On the other hand, the hinge rod 122 drives multiple movable rods 120 to converge inward, so that the shield 121 gathers and wraps around the bulb 200, preventing the bulb 200 from being exposed to the outside world and causing dust corrosion. This is beneficial to the protection of the bulb 200 and improves its service life.

[0046] Therefore, by adjusting the shield 121 of the lampshade mechanism 100 to open or close for protection, the waterproof, insect-proof, and dustproof effects of the industrial and mining lamp are met. When the shield 121 is open, it prevents rainwater from falling from the top and also prevents dust from falling on the bulb 200, thus achieving a dustproof effect. When the shield 121 is closed, the bulb 200 and the electromagnetic induction mechanism 300 are protected inside the shield 121, reducing the contact of insects with the bulb 200, thus realizing the function of a three-proof industrial and mining lamp.

[0047] First, the specific structure of the electromagnetic induction mechanism 300 is disclosed. Please refer to [link / reference]. Figures 6-7 To enable the bulb 200 to emit light without wiring, the electromagnetic induction mechanism 300 includes at least a connecting rod 310 fixed to the end of the fixed rod 110. The outer wall of the connecting rod 310 has two symmetrical support rods 311, and each support rod 311 has an arc-shaped magnet 320 at its end.

[0048] An electrical connection cover 330 is provided at the end of the connecting rod 310. The electrical connection cover 330 is connected and fixed to the bulb 200. A copper wire 331 is wound around the outer wall of the electrical connection cover 330. The two ends of the copper wire 331 are respectively wound between two arc-shaped magnets 320 to generate electromagnetic resonance. When the magnetic ring 130 slides into the electrical connection cover 330 and is located between the two arc-shaped magnets 320, the bulb 200 generates electromagnetic induction to emit light. This realizes that when the magnetic ring 130 slides inward, electromagnetic induction is generated to make the bulb 200 emit light. At the same time, multiple movable rods 120 unfold to focus the light, making it easy to open and avoiding the operation of wiring the bulb 200, which is more energy-saving and environmentally friendly.

[0049] Because the bulb 200 is inconvenient to disassemble and install after being connected to the electrical connection cover 330, it is inconvenient to replace it if it is damaged. Therefore, if Figure 8 As shown, an installation assembly 340 is provided between the electrical connection cover 330 and the bulb 200. The installation assembly 340 includes at least a plug 341 connected to the end of the electrical connection cover 330. The end of the bulb 200 is provided with a sleeve 210. The plug 341 and the sleeve 210 are plugged in and connected. The copper wire 331 is wound around the electrical connection cover 330 to realize the electrical connection between the bulb 200 and the electrical connection cover 330. The wound copper wire 331 acts as a coil, so that when the magnetic ring 130 is located inside the arc magnet 320, it generates electromagnetic induction to drive the bulb 200 to light up.

[0050] Specifically, a groove 342 is provided on the outer wall of the insert 341, and an elastic locking block 343 is slidably provided inside the groove 342. A slot 211 is provided on the outer wall of the insert sleeve 210. When the insert 341 rotates inside the insert sleeve 210, the elastic locking block 343 is aligned with the slot 211 and engaged. When installing the bulb 200, the insert sleeve 210 is first aligned with the insert 341 and inserted. At this time, the elastic locking block 343 slides into the groove 342 and generates a rebound force. Then, the bulb 200 is rotated so that the elastic locking block 343 is aligned with the slot 211. Under the action of the rebound force of the elastic locking block 343, it is inserted into the slot 211, realizing the installation between the electrical connection cover 330 and the bulb 200. Conversely, when disassembling, the bulb 200 only needs to be rotated forcefully so that the elastic locking block 343 is subjected to external force and slides into the groove 342, and the bulb 200 can be removed for subsequent maintenance and replacement.

[0051] Since the bulb 200 is exposed to the air when it is in use, dust will float on the outer wall of the bulb 200. Therefore, the inner diameter of the magnetic ring 130 is matched with the outer diameter of the bulb 200. When the bulb 200 is turned on by sliding the magnetic ring 130, the inner wall of the magnetic ring 130 scrapes the dust off the outer wall of the bulb 200, so as to avoid dust from adhering for a long time and affecting the lighting effect, and improve the service life.

[0052] In addition, in order to enable the adjustable lampshade mechanism 100 to be suspended, a suspension plate 140 is provided at the end of the fixed rod 110, and a hanging ring is provided at the end of the suspension plate 140. The hanging ring is used to suspend and support the adjustable lampshade mechanism 100, so that the hook can be fixed to the ceiling of industrial plants, production workshops, supermarkets, sports and entertainment venues and warehouses, and then the hanging ring is put on the hook so that the suspension plate 140 supports the entire device, so that the bulb 200 can be used as an industrial and mining lamp for illumination.

[0053] To make it easier to control the up-and-down movement of the magnetic ring 130, that is, to make it easier for users to control the on / off state of the bulb 200, please refer to [link / reference needed]. Figures 9-10 The second embodiment of the present invention is shown, wherein a linkage control component 150 is provided on the outer wall of the magnetic ring 130, wherein:

[0054] The linkage control component 150 includes a pull rope 152 fixed to the outer wall of the magnetic ring 130. The pull rope 152 moves through the fixed rod 110 and is located outside the shield 121. The user can pull the pull rope 152 to drive the magnetic ring 130 to move upward, that is, to move inward into the electromagnetic induction mechanism 300, so that the shield 121 opens and drives the bulb 200 to light up. Conversely, after the pull rope 152 is released, the magnetic ring 130 moves downward along the bulb 200 under its own weight, so that the shield 121 closes and the bulb 200 is turned off, which facilitates the control of the bulb 200's opening and closing.

[0055] To make pulling the pull rope 152 easier and prevent it from getting tangled on the outer wall of the movable rod 120 and causing damage, the linkage control component 150 also includes a support frame 151 fixed to the outer wall of the suspension plate 140. The pull rope 152 is located inside the support frame 151 and is pulled. A wheel 153 is rotatably provided at the end of the support frame 151. The wheel 153 is used to switch the pulling angle of the pull rope 152 from the horizontal direction to the vertical direction, so that the user can pull the pull rope 152 vertically downward, which can drive the magnetic ring 130 to move up and down. At the same time, the wheel 153 can guide the position of the pull rope 152, so that the pull rope 152 is located inside the support frame 151, preventing it from getting tangled in other places and affecting the sliding effect of the magnetic ring 130.

[0056] If the light bulb 200 is turned on while the pull rope 152 is being pulled, the user will experience high physical exertion from constantly pulling the rope 152. Therefore, if Figure 10 As shown, a limiting component 154 is provided at the end of the pull rope 152. The limiting component 154 includes at least a winding frame 1541. A winding roller 1542 is rotatably provided inside the winding frame 1541. The pull rope 152 is wound around the outer wall of the winding roller 1542, wherein:

[0057] The end of the roller 1542 extends out of the winding frame 1541 and is connected to a limiting plate 1543. The surface of the limiting plate 1543 has multiple equally spaced insertion holes 1544. When the limiting plate 1543 rotates to a suitable angle, a pin passes through one of the insertion holes 1544 to limit and fix the limiting plate 1543. The winding frame 1541 can be fixed to the wall or the ground with bolts. Rotating the limiting plate 1543 drives the roller 1542 to rotate, and the pull rope 152 is wound around the roller 1542, so that the pull rope 152 pulls the magnetic ring 130. At the same time, the rotation of the limiting plate 1543 is limited by the pin passing through one of the insertion holes 1544, so that the light bulb 200 is kept on. Conversely, when the light bulb 200 is turned off, the pin only needs to be removed from the insertion hole 1544. Under the action of gravity, the magnetic ring 130 is disengaged from the electromagnetic induction mechanism 300, saving the labor intensity of opening and closing.

[0058] In summary, when this invention is used in practice:

[0059] First, by fixing the winding frame 1541 to the wall or ground with bolts, when the bulb 200 is turned on: rotating the limiting plate 1543 drives the roller 1542 to rotate, and the pull rope 152 is wound around the roller 1542, so that the pull rope 152 pulls the magnetic ring 130, causing the magnetic ring 130 to move upward. When the magnetic ring 130 slides into the inside of the electrical connection cover 330 and is located between the two arc-shaped magnets 320, the bulb 200 generates electromagnetic induction to emit light. At the same time, the hinge rod 122 causes multiple movable rods 120 to open, and the movable rods 120 drive the shield 121 to open to form a lampshade shape, so that the light of the bulb 200 shines out from the opening at the lower end of the shield 121.

[0060] When the bulb 200 is not in use, the pin is removed from the socket 1544. Under the action of gravity, the magnetic ring 130 is disengaged from the electromagnetic induction mechanism 300, stopping the generation of electromagnetic induction effect, which means that the illumination of the bulb 200 is turned off. At the same time, the hinge rod 122 drives multiple movable rods 120 to converge inward, so that the shield 121 gathers and wraps around the bulb 200, preventing the bulb 200 from being exposed to the outside world and causing dust corrosion. This is beneficial to the protection of the bulb 200 and improves its service life.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
