The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After the power management module output direct current through 2M active crystal inverter converted into highFrequency alternating current is supplied to the primary winding.
Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting from the charging baseThe charger, using the latest wireless charging technology, transmits electricity magically by using the magnetic field generated between the coils, and the inductive coupling technology will become a bridge connecting the charging base station and the equipment. How to use: Connect the USB cable and plug it into the socket.
3, wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
4, wireless charging againCalled inductive charging, non-contact inductive charging, derived from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
5, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
6, car wireless charging is aA new type of charging technology, which does not need to connect the car and the power supply through the traditional physical charging line, but realizes the wireless transmission of electric energy through the electromagnetic field. The principle of automobile wireless charging technology is to use the principle of electromagnetic induction or electromagnetic resonance to achieve wireless transmission of electric energy. When a magnetic field is formed between the power supply and the receiver, electrical energy can be transferred to the interior of the car through the magnetic field to charge the battery.
In summary, several light Sculptor music desk lamp is quite bright in function and design, but the details need to be improved. For consumers looking for good gifts, it is certainly worth considering, but at a price of 500, the sound performance may leave some discerning music lovers feeling inadequate. Overall, this product is suitable for both creative and practical users, butThe price-performance aspect may be debatable.
This kind of music desk lamp generally can not wireless charging mobile phones, now wireless charging words only that kind of small disc, like you this kind of music desk lamp, it must still need a line connection, there is no connection then it must be that, well, there is not much of the role, so you still need to pass a certain connection. Technology that uses magnets to charge devices.
If the resistance of the gas in the lamp is much smaller than that of the air, it is said that its resistance is one thousand times smaller than that of the air. And because the radio is also a kind of energy, because the lamp resistance is much smaller, as long as the lamp byNear the radio waves, the current converted into radio waves in the lamp will be much larger than the current converted into the air, because the lamp is not very large, the gas inside will quickly glow under the action of electric heating.
The method of use is as follows: After plugging in the power supply, touch the arc light pole with your finger at any position to turn on the light. Put the device that needs to be charged under the lamp, switch the mobile phone to the wireless charging mode, and put it into the wireless charging induction area of the lamp. Use the phone charging cable to connect the lamp USB port to the phone, and the phone can also be charged.

On its flat and smooth base panel, you can't see a protruding button, but there is a bold and simple icon, which is just like a mobile phone. You can light up the power button with your finger and shut down the operation.
The method of use is as follows: After plugging in the power supply, touch the arc lightly with your fingerThe light pole can be lit at any position. Put the device that needs to be charged under the lamp, switch the mobile phone to the wireless charging mode, and put it into the wireless charging induction area of the lamp. Use the phone charging cable to connect the lamp USB port to the phone, and the phone can also be charged.
Wireless charging intelligent desk lamp using panel light source, light outlet length of about 15cm, wide lighting range, uniform brightness, built-in 112 LED lamp beads, it is said to be able to use 30,000 hours, according to the use of 8 hours a day, can be used for 10 years. Wireless charging, desktop has never been so clean. Touch design, three touch buttons below, according toThe second is the light switch key, the on key and the timed shutdown key.
General charging lamp can be used for how long, the first charge takes about eight hours, after each charge is almost four or five hours can be used for two to three hours each time. Wireless charging desk lamps are still relatively few in our actual life, and rarely touched.
This kind of music desk lamp generally can not give mobile phone wireless charging, now wireless charging words only that kind of small disc, like you this kind of music desk lamp it must still need a line connection, no connection then it must be that, well, there is not much of the effectSo you still have to go through certain connections.
