Description

Technical Field

[0001] The present invention relates to the technical field of track lights, and in particular to a wireless powered waterproof track light. Background Art

[0002] The current track light structure is shown in reference to publication number WO2018157567A1 and Taiwan patent publication M619216. It is usually implemented with a track for fixing on a wall or ceiling. The bottom surface of the track is formed with an opening connected to the interior thereof, and two conductive plates are provided in the track. The two conductive plates are connected to a transformer through wires. In addition, a slide seat is provided in a lamp. The slide seat is provided with conductive terminals for contacting the two conductive plates. The slide seat of the lamp is installed under the opening of the track, so that the two conductive terminals of the slide seat contact the two conductive plates to supply power. Therefore, the lamp can be installed at any position on the track, and the lamp can be powered at any position on the track.

[0003] However, the track of the known track light adopts a structure with an opening on the bottom surface, which makes it easy for water and moisture to penetrate. Therefore, the installation place of the known track light can only be limited to indoors, and cannot be used outdoors or even in water. If the track of the track light is implemented as a closed structure to prevent the intrusion of water and moisture, the problem of the conductive terminal of the external lamp cannot contact the two conductive plates in the track will occur. In addition, the known track light needs to use a complex mechanical assembly structure, such as using components such as latches, sliders, and fixing screws to install the lamp on the track, so its manufacturing cost is high, and the actual installation and adjustment are very inconvenient, for example, multiple fixing screws must be loosened to move the lamp on the track. Summary of the invention

[0004] The main purpose of the present invention is to provide a wireless power supply waterproof track light, which achieves the function of wireless power supply by providing one or more wireless power supply transmitting modules in a power supply track and a wireless power supply receiving module provided in a lamp, and through the technology of magnetic adsorption, the lamp can be arbitrarily adsorbed on the power supply track.

[0005] A second object of the present invention is to provide a wireless power supply waterproof track light. Through the above-mentioned wireless power supply and magnetic adsorption design, the power supply track can be implemented as a closed track, so that the wireless power supply transmitting module will not be exposed to rainwater in the power supply track, and can be used as an outdoor waterproof track light.

[0006] In order to achieve the above-mentioned purpose, the wireless power supply waterproof track light of the present invention has a preferred technical solution including a power supply track, a wireless power supply transmitting module and a lamp, wherein:

[0007] The power supply track has a track body and two conductive strips. The outer surface of the track body has a lamp installation surface. The interior of the track body has a closed sliding space corresponding to the lamp installation surface. The two conductive strips are arranged in the closed sliding space and extend parallel to the lamp installation surface to supply power to the wireless power transmission module.

[0008] The wireless power transmission module comprises a sliding body, a transmitting coil, two conductive terminals and a first magnet; the sliding body is arranged in the closed sliding space of the track body, and is used to arbitrarily move its position in the closed sliding space; the transmitting coil is arranged in the sliding body, and is used to generate a magnetic field in the closed sliding space toward the installation surface of the lamp; the two conductive terminals are fixed to the sliding body and connected to the transmitting coil, and the two conductive terminals are movably in contact with the two conductive strips; the first magnet is fixed to the sliding body, and is used to be mutually attracted with the lamp;

[0009] The lamp includes a lamp body, a receiving coil and a second magnet. The lamp body can be detachably arranged on the lamp mounting surface of the track body and its position can be moved on the lamp mounting surface; the receiving coil is arranged on the lamp body, and the receiving coil can sense the magnetic field of the transmitting coil to generate an induced current and supply power to the lamp body; the second magnet is fixed to the lamp body and is used to adsorb with the first magnet through its magnetism, so that the lamp body can be detachably adsorbed on the lamp mounting surface.

[0010] The present invention can achieve the following effects:

[0011] (1) Wireless power supply to lamps by power supply track: The present invention can supply power to track lamps by wireless power supply through the transmitting coil on the primary side of the wireless power supply transmitting module and the receiving coil on the secondary side of the lamp body.

[0012] (ii) It can be applied as a waterproof track light: The present invention uses wireless power supply technology to eliminate the need for conventional track lights to use conductive terminals in contact with two conductive strips. The track body can be implemented as a tube with both ends closed, and the lamp can also be implemented as a fully sealed structure, thereby achieving the effect that the track light can be waterproof and installed outdoors.

[0013] (III) Random adsorption and position adjustment: The power supply track and the lamp are attracted to each other by magnetic force, without any known complex mechanical fixing structure, so that the lamp can be adsorbed at any position of the power supply track, making it more convenient for users to install and adjust the position.

[0057] See also Figure 1 and Figure 2 As shown, the wireless power supply waterproof track light of the present invention is a waterproof track light used to be installed on a wall or ceiling and can be moved and adjusted at will. The preferred embodiment includes a power supply track 10, a wireless power supply transmitter module 20 and a lamp 30. The wireless power supply transmitter module 20 is installed in the power supply track 10, so that the wireless power supply transmitter module 20 supplies power to the lamp 30 adsorbed on the power supply track 10 through wireless charging technology, wherein:

[0058] See also Figure 2 and Figure 3As shown, the power supply track 10 preferably has a track body 11 and two conductive strips 12. The outer surface of the track body 11 has a lamp mounting surface 111. The inside of the track body 11 has a closed sliding space 112 corresponding to the lamp mounting surface 111. The two conductive strips 12 are arranged in the closed sliding space 112 and extend parallel to the lamp mounting surface 111 to supply power to the wireless power transmission module 20. Among them, the track body 11 is preferably implemented with a tube body 13, two end covers 14 and a power line 15. The tube body 13 can be an aluminum extruded straight square tube or an arc square tube. A plane outside the square tube is used as the lamp mounting surface 111, and one or more lamps 30 are adsorbed on the lamp mounting surface 111 by magnetic force. The inside of the square tube is used as the above-mentioned closed sliding space 112 and two shaped mounting grooves 131 can be provided on the inner tube wall of the tube body 13, and the two conductive strips 12 are fixed to the two shaped mounting grooves 131. The two end caps 14 respectively cover the two ends of the tube body 13 in a sealed manner to prevent water and moisture from entering the sealed sliding space 112. One end of the power cord 15 passes through the end cap 14 or the tube wall of the tube body 13 to enter the sealed sliding space 112 and is connected to the two conductive strips 12, and the other end is connected to a power source (such as a transformer, etc.). The conductive strip 12 is preferably a copper strip, and one side of the conductive strip 12 is combined with an insulator 16, so that each conductive strip 12 or the insulator 16 is fixed in the two-shaped mounting groove 131, which can be used to power the wireless power transmission module 20.

[0059] See also Figure 3 , Figure 4 and Figure 5 As shown, the wireless power transmission module 20 preferably has a sliding body 21, a transmitting coil 22, two conductive terminals 23, two first magnets 24 and a magnetically controlled switch 25. The sliding body 21 is disposed in the enclosed sliding space 112 of the track body 11, and its position can be moved arbitrarily in the enclosed sliding space 112. The transmitting coil 22 is a copper coil wound into a ring, which is disposed on the sliding body 21, and generates a magnetic field in the enclosed sliding space 112 toward the lamp installation surface 111. The two conductive terminals 23 are components stamped from copper sheets, which are respectively fixed to the sliding body 21 and connected to the transmitting coil 22, so that the two conductive terminals 23 contact the above-mentioned two conductive strips 12 and move with the sliding body 21 (such as Figure 5As shown). The first magnet 24 is a permanent magnet fixed on the sliding body 21, and is mutually attracted to the lamp 30 outside the track body 11. The magnetic control switch 25 is an existing electronic component, connected to the circuit of the transmitting coil 22. When the lamp 30 is attracted to the lamp installation surface 111, the magnetic control switch 25 forms a path through the magnetism of the third magnet 36 of the lamp 30, and then the transmitting coil 22 is powered. On the contrary, when the lamp 30 is detached, the magnetic control switch 25 is disconnected, and the transmitting coil 22 will no longer consume power.

[0060] See also Figure 4 As shown, the configuration of the sliding body 21 is not limited, and is preferably implemented as a first shell 211 and a first cover 212. The first shell 211 has a plurality of mounting grooves 214, 215, 216, and 217 for mounting the transmitting coil 22, the two conductive terminals 23, the first magnet 24, and the magnetic switch 25, so as to form a modular component, which is convenient for loading a plurality of wireless power transmission modules 20 into the track body 11. The mounting groove 215 of the first shell 211 for the two conductive terminals 23 has two openings 218 connected to the outside of the first shell 211; and the two conductive terminals 23 are respectively provided with a conductive spring 231. When each of the conductive terminals 23 is fixed in the mounting groove 215, the conductive spring 231 protrudes from the outside of the first shell 211 through the opening 218 (such as Figure 3 As shown), the conductive spring 231 can movably contact the two conductive strips 12, and the sliding body 21 (first housing 211) moves to any position (as shown) of the track body 11. Figure 5 ) can supply power to the transmitting coil 22.

[0061] See also Figure 6 and Figure 7 As shown, the lamp 30 preferably has a lamp body 31, a receiving coil 32 and a second magnet 33. The lamp body 31 is an existing LED lamp, which is used in the present invention to be detachably arranged on the lamp mounting surface 111 of the track body 11, and can be moved on the lamp mounting surface 111. The receiving coil 32 and the transmitting coil 22 are both copper coils wound into a ring, which can be arranged in a wireless power receiving module 34 at the rear end of the lamp body 31 or directly installed in the rear end of the lamp body 31. When the receiving coil 32 is close to the transmitting coil 22, the receiving coil 32 can sense the magnetic field of the transmitting coil 22 to generate an induced current to supply power to the lamp body 31. The second magnet 33 is fixed in the wireless power receiving module 34 of the lamp body 31 or directly installed in the rear end of the lamp body 31, and is used to adsorb with the first magnet 24 of the wireless power transmitting module 20 through its magnetism, so that the lamp body 31 can be detachably adsorbed on the lamp installation surface 111.

[0062] See also Figure 6 and Figure 7 As shown, the wireless power receiving module 34 has a second shell 341 and a second cover 342. The second shell 341 or the second cover 342 is combined with the rear end or one side of the lamp body 31 through a direction adjustment structure 35. The receiving coil 32 and the second magnet 33 are fixed in the second shell 341 respectively, so that the wireless power receiving module 34 is attracted to the first magnet 24 through the second magnet 33, and then the lamp body 31 is detachably adsorbed on the lamp installation surface 111 of the track body 11 and the adsorption position can be moved to adjust. Among them, the direction adjustment structure 35 can be an existing universal joint, so that the lamp body 31 can adjust the irradiation angle. See also Figure 8 As shown, the present invention does not need to implement the second shell 341 and the second cover 342, and directly fixes the receiving coil 32 and the second magnet 33 inside the lamp housing 311 at the rear end of the lamp body 31, respectively, and can also achieve the effect of attracting the first magnet 24. In addition, the wireless power receiving module 34 (second shell 341) or the lamp housing 311 of the lamp body 31 of the present invention is further provided with a rectifier circuit board 37, which is connected between the receiving coil 32 and the light-emitting unit of the lamp body 31 to provide electrical energy to the lamp body 31.

[0063] See also Figure 1 and Figure 2 As shown, when the present invention is used, the power supply track 10 can be fixed on a wall, ceiling or other object. Each power supply track 10 is preset with a plurality of wireless power supply transmitting modules 20. As long as the rear end of the lamp 30 is placed against the lamp installation surface 111 of the track body 11, the second magnet 33 thereof can be attracted to the first magnet 24 of the wireless power supply transmitting module 20 to fix the lamp 30 on the lamp installation surface 111. The lamp 30 can also be moved to allow the wireless power supply transmitting module 20 to move together in the closed sliding space 112. It is worth mentioning that the present invention uses the technology of wireless power supply to eliminate the need for the open structure technology of the known track lamp, in which the lamp must use a conductive terminal to contact two conductive strips. The track body 11 can be implemented as a tube body with closed ends, and the lamp 30 can also be implemented as a fully sealed structure, thereby achieving the effect that the track lamp can be waterproof and installed outdoors.
