Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a wirelessly connected lamp device that is easy to replace and a replacement method thereof. Background Art

[0002] Lamps are devices used to provide lighting. They play an important role in human life, not only meeting basic lighting needs, but also adding beauty and atmosphere to the environment. There are many types of lamps, including chandeliers, wall lamps, table lamps, floor lamps, etc., which can be selected according to different usage scenarios and decoration styles. With the development of technology, modern lamps are not only more diversified in design, but also more intelligent in function, such as adjustable brightness, color temperature, and even remote control through smart home systems. The materials of lamps have also evolved from traditional metals and glass to modern LED technology, making lighting more energy-saving and environmentally friendly. Whether it is home, office or public places, the right lamps can enhance the comfort and functionality of the space.

[0003] Common household ceiling lights, downlights and flat panel lights all have a certain service life. When the lamps reach the end of their service life, they need to be replaced. Common lamps need to be connected to the live and neutral wires of the mains when replacing them. In daily life, not many people know how to connect and replace wires, especially women and the elderly. If the live and neutral wires are connected in reverse when installed, electric shock accidents are likely to occur. In addition, existing lamps usually use a single ground wiring power supply mode. When the mains fails, the lamps in the home will not be able to continue to illuminate, and the lighting system with emergency power supply cannot be disassembled and used.

[0030] Beneficial effects:

[0031] 1. The present invention fixes the insulating sleeve on the installation wall, uses the control circuit board to connect to the mains power, and then screws the connector on the lamp body into the docking groove. When screwing in, the conductive outer ring sheet and the conductive wrapping sheet are threadedly engaged. After tightening, the lamp body contact sheet and the conductive contact sheet are in contact. At this time, the current is conducted through the conductive outer ring sheet and the lamp body contact sheet, and then passes through the lamp body. After the lamp body, the lamp body contact sheet and the conductive outer ring sheet are conducted to form a complete current loop for power supply. When disassembling, you only need to unscrew the lamp body and replace it with a new lamp body and screw it into the docking groove.

[0032] 2. The present invention uses a mobile power supply as a backup power supply, and can use the mobile power supply to supply power when the mains power fails. The mobile power supply uses electromagnetic induction to convert the induced potential into an induced current through the first induction coil and the second induction coil to supply power to the lamp body. At the same time, when the mains power fails, the connector can be unscrewed, and after the lamp body is removed, the connector can be placed on a mobile power supply that supports wireless charging, thereby realizing the function of serving as an emergency movable light source. No wiring is required during connection and removal, and disassembly and assembly are convenient, which is convenient for people without circuit wiring technology to operate.

[0033] 3. The present invention connects the AC power to the control circuit board. The AC power can be stepped down by the step-down module in the control circuit board. The first rectifier and voltage regulator chip is used to perform rectification and support positive and reverse connection, thereby simplifying the operation during the initial wiring. It is only necessary to connect the AC power ground and neutral wires to the control circuit board respectively, and the step-down module is arranged on the power supply end. When the lamp body is subsequently replaced, even if the neutral and live wires are reversed during wiring, the control circuit board can always keep the live wire connected to the conductive contact sheet and the neutral wire connected to the conductive outer ring sheet, thereby preventing the live wire and the user's ground from forming a loop and causing electric shock when the user touches the conductive wrapping sheet area due to the reversed wire connection when replacing the lamp body.

[0069] S1: When the mains electricity is normally used to supply power through the first input line 7 and the second input line 8, the mobile power supply 401 can be charged through the control circuit board 600 and the connecting line 402. At this time, the mobile power supply 401 does not discharge.

[0070] S2: When there is a power outage or external mains failure, the mobile power supply 401 discharges, and the current passes through the high-frequency oscillation circuit in the control circuit board 600 to generate a high-frequency oscillation signal, thereby generating a strong and rapidly changing magnetic field.

[0071] S3: The second induction coil 501 generates an induced electromotive force in the magnetic field, and the induced electromotive force forms an induced current in the closed loop. The generated induced current is rectified and stabilized by the second rectifier and voltage regulator chip 502 on the second circuit board 500 to output stable direct current. At this time, the lamp body 1 is lit.

[0072] S4: The wireless induction power receiving module 5 is integrated into the connector 9 like the thin-film connection power receiving module 2. When replacing, just unscrew the old lamp body 1 from the docking slot 15 and remove it, and replace it with a new lamp body 1 and screw it into the docking slot 15.

[0073] S5: After the mains power is restored, the control circuit board 600 cuts off the power supply of the mobile power supply 401 , and uses the mains power to supply power through the first input line 7 and the second input line 8 , and charges the mobile power supply 401 .

[0074] During installation, the mobile power supply 401 is connected to the control circuit board 600 through the connecting line 402, and the current of the mobile power supply 401 will be directly input and output through the control circuit board 600. When the mobile power supply 401 is selected, a battery that matches the voltage of the lamp should be selected, and the position of the mobile power supply 401 can be freely set. It only needs to be connected to the control circuit board 600 through the connecting line 402. The mobile power supply 401 is used as a backup power supply, and can be used to supply power when the mains power fails. The mobile power supply 401 uses electromagnetic induction to convert the induced potential into an induced current through the first induction coil 400 and the second induction coil 501 to power the lamp body 1. At the same time, when the mains power fails, the connector 9 can also be unscrewed, and after the lamp body 1 is removed, the connector 9 is placed on a mobile power supply that supports wireless charging, and the mobile power supply that supports wireless charging is used to temporarily replace the mobile power supply 401 as energy supply, thereby realizing the function of serving as an emergency movable light source, and no wiring is required during connection and removal, and the disassembly and assembly are convenient, which is convenient for people who do not have circuit wiring technology to operate, and the remaining features are the same as those of Example 1.

[0075] Embodiment 3: Figure 14-15In order to improve the safety of operation during connection and replacement and realize the function of simple installation, the positive terminal on the wired connection interface 601 is electrically connected to the conductive contact sheet 303 through a wire, the negative terminal on the wired connection interface 601 is electrically connected to the conductive outer ring sheet 302 through a wire, and the two output terminals on the wireless connection interface 602 are electrically connected to the two ends of the first induction coil 400 respectively. The first rectifier and voltage regulator chip 301 and the second rectifier and voltage regulator chip 502 are both provided with a full-bridge rectifier circuit for rectification, and the first rectifier and voltage regulator chip 301 and the second rectifier and voltage regulator chip 502 are both provided with a three-terminal voltage regulator for voltage stabilization. A transformer is provided in the step-down module 300 for step-down, and the output terminal of the full-bridge rectifier circuit is electrically connected to the wired connection interface 601. A high-frequency oscillation circuit is provided in the control circuit board 600, and the output terminal of the high-frequency oscillation circuit is electrically connected to the wireless connection interface 602. The positive pole in the lamp body 1 is electrically connected to the lamp body contact thin sheet 201, and the negative pole in the lamp body 1 is electrically connected to the conductive outer ring sheet 302. The electric wrapping sheet 200 is electrically connected to connect the AC power to the control circuit board 600. The buck module 300 in the control circuit board 600 can buck the AC power, so that the 220V AC current can be reduced to a voltage suitable for the lamp. The first rectifier and voltage regulator chip 301 is used to rectify and support positive and reverse connection, so that the initial wiring is simplified. It is only necessary to connect the AC ground and neutral wires to the control circuit board 600 respectively, and the buck module 300 is set on the power supply end. When the lamp body 1 is replaced later, even if the neutral and live wires are reversed during wiring, under the action of the full-bridge rectifier circuit in the first rectifier and voltage regulator chip 301, the live wire can always be connected to the conductive contact piece 303, and the neutral wire can be connected to the conductive outer ring piece 302. This can avoid the user's hand touching the conductive wrapping sheet 200 area when replacing the lamp body 1 due to the reversed wires, resulting in a loop between the live wire and the user's grounding to cause electric shock, making subsequent installation and replacement safer. The remaining features are the same as those in Example 1.

[0076] The working principle of the present invention is as follows: during installation, a mounting hole 11 having the same size as the insulating sleeve 12 is opened on the mounting wall 10, and then the insulating sleeve 12 is fixed in the mounting hole 11 by glue, the main power supply of the mains is turned off, and the two connecting lines of the mains, the first input line 7 and the second input line 8, are respectively connected to the control circuit board 600 through the insulating sleeve 12, and the positive terminal on the wired connection interface 601 is electrically connected to the conductive contact piece 303 through the wire, and the negative terminal on the wired connection interface 601 is electrically connected to the conductive outer ring piece 302 through the wire. When the external power supply is connected to the control circuit board 600, it is first stepped down by the step-down module 300, and then rectified by the first rectifier and voltage regulator chip 301. The diode in the first rectifier and voltage regulator chip 301 Under the action of the bridge circuit, the live wire end of the mains electricity can be turned on from the positive pole of the wired connection interface 601, and the neutral wire end of the mains electricity can be turned on from the negative pole of the wired connection interface 601. The mobile power supply 401 is connected to the control circuit board 600 through the connecting wire 402. The current of the mobile power supply 401 will be directly input and output through the control circuit board 600. When the mobile power supply 401 is selected, a battery that matches the voltage of the lamp should be selected, and the position of the mobile power supply 401 can be freely set. It only needs to be connected to the control circuit board 600 through the connecting wire 402. After the power supply ends are installed, the connector 9 on the lamp body 1 is screwed into the docking groove 15. When screwing in, the conductive outer ring piece 302 and the conductive wrapping piece 200 are threadedly engaged. When the connector 9 is screwed into place , the lamp body contact sheet 201 is in contact with the conductive contact sheet 303. At this time, the charge is connected from the conductive contact sheet 303 to 202, passes through the inside of the lamp body 1, and then flows out through the conductive wrapping sheet 200 and the conductive outer ring sheet 302 to form a complete circuit. At this time, the AC power supply is turned on, and the control circuit board 600 will give priority to using the AC power to power the lamp body 1 (this is a prior art, which is applied to mobile phones that cannot use wired charging and wireless charging at the same time). At this time, the lamp body 1 can be lit. It is worth mentioning that: the shape of the lamp body 1 is not limited to the "light bulb" shape shown in the legend. Its outer shell can be a disc or rectangle of a ceiling lamp. As long as its connection structure and power supply structure are consistent with the above-mentioned technical means, the wiring-free method to be achieved by the present invention can be achieved. The function of replacing lamps is not limited by the shape of lamps. The outer contour shape of the lamp body 1 can be changed at will during production. It is only necessary to ensure that the top is connected to the power supply through the above-mentioned connection method. When the lamp body 1 needs to be replaced after being used for a period of time, after turning off the mains power, turn the lamp body 1 counterclockwise, remove the connector 9 from the docking slot 15, and screw the new lamp body 1 back into the docking slot 15 and then turn on the mains power again. Subsequent replacements do not require secondary power connection, and the mains power is connected to the control circuit board 600. The step-down module 300 in the control circuit board 600 can step down the mains power, so that the 220V mains current can be reduced to a voltage suitable for the lamp, and the first rectifier and voltage regulator chip 301 is used for rectification and supports positive and reverse connection.To achieve simplified operation at the initial wiring, only the live and neutral wires of the mains power supply need to be connected to the control circuit board 600 respectively, and the step-down module 300 is set on the power supply end. When the lamp body 1 is replaced later, even if the live and neutral wires are reversely connected during wiring, under the action of the full-bridge rectifier circuit in the first rectifier and voltage-stabilizing chip 301, the live wire can always be connected to the conductive contact piece 303, and the neutral wire can be connected to the conductive outer ring piece 302. This can prevent the live wire and the user's grounding from forming a loop and causing electric shock when the user touches the conductive wrapping piece 200 due to the reversed wire connection when replacing the lamp body 1, making the subsequent installation and replacement safer. As a backup power source, the mobile power source 401 can be used to supply power when the mains fails. The mobile power source 401 uses electromagnetic induction to convert the induced potential into an induced current through the first induction coil 400 and the second induction coil 501 to supply power to the lamp body 1. At the same time, when the mains fails, the connector 9 can be unscrewed, and after the lamp body 1 is removed, the connector 9 is placed on a mobile power source that supports wireless charging. The mobile power source that supports wireless charging temporarily replaces the mobile power source 401 as a power supply, thereby realizing the function of serving as an emergency movable light source. No wiring is required during connection and removal, and the assembly and disassembly are convenient, which is convenient for people without circuit wiring technology to operate.
