A wall lamp is a type of lighting device that is mounted on a wall and designed to provide partial illumination to the surrounding environment, rather than directly illuminating the entire space or roof. Wall lamps are used for indoor lighting to provide people with a comfortable atmosphere and meet the light required for a specific event. Decorative role Wall lamps are used for indoor lighting and sometimes play a decorative role.
Wall lamp is an auxiliary lighting decorative lamp installed on the indoor wall, which plays the role of lighting and decoration. There are many types and styles of lamps, such as ceiling lamps, color-changing wall lamps, bedside wall lamps, and mirror front wall lampsLet's wait. Such as a large room can install double fire wall lamp, small room can install single fire wall lamp. The color of the wall lamp should be coordinated with the color of the installation wall.
There is also a wall light that is mostly used for balconies, walkways and stairs. This love is not suitable for use in the bedroom, otherwise it will have a great impact on the feng shui of love between husband and wife. This in the bedroom bedside wall lamp feng shui must be paid attention to.
Living room lighting should be noted that the living room is a place to entertain guests, too dim light will affect the owner's career development. If the living room is bright and not dim, it means that you can have a prosperous. Some visitors lack sunlight exposureHall, the room is dark and unclear, and it is easy to feel depressed for a long time. In this case, it is best to fill the light by hiding fluorescent lamps in the wood slots on the four sides of the ceiling, so that the light is refracted from the ceiling, soft and not dazzling.
2, wireless charger use method: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontal in the wireless charger base left and right center position, that isWireless charging can be achieved, the indicator light will have a breathing effect, 5 seconds after the extinguishment, plug and play, convenient and quick.

Huawei supports wireless charging models such as Huawei P40Pro, Huawei P30Pro, Huawei Mate30Pro. Huawei P40Pro supports 40W super fast charge, 27W wireless fast charge, and wireless reverse charge. Huawei P30Pro supports 40W super fast charge and 15W wireless fast charge. Huawei Mate30Pro mobile phone supports a maximum of 10V / 4A super fast charge, compatible with 4.5V / 5A or 5V / 4.5A super fast charge, compatible with 9V / 2A fast charge.
Apple: iphone support wireless charging models are iPhone PhoneX series, iPhone11 series, iPhone12 series, iPhone13 series, and iPhone 2 and later. These Apple phones have induction coils added to the back, and can be charged using wireless magnetic induction charging devices.
There are many mobile phones that support wireless charging now, and the common ones are as follows: Nut R1 Nut R1 is a flagship mobile phone released by Hammer technology in May 2018, and it is also the first hammer mobile phone that supports wireless charging. In terms of appearance, the Nut R1 uses a three-narrow bezel shaped full screen design, the beauty pointed front camera fringe design, and the jaw is relatively narrow, screenThe proportion is very high.
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 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 AC mains at the input end is converted by the full bridge rectifier circuitDirect current, or use 24V DC terminal directly to supply power to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging source is installed inside a electromagnetic coil, after opening the power switch, the electromagnetic coil will convert the power supply battery into a large amount of magnetic energy, and then use a reverse coil (international standard brick QI coil), receive this large amount of magnetic energy, convert it into electrical energy, through a metal output head, into our equipment reserve battery. Wireless charging because electromagnetic transmission only needs to be transmitted in space, no interface is requiredQuality, so you can wireless charging.
Wireless charging, also known as inductive charging, non-contact inductive charging, 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.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, and uses the latest wireless charging technology through the use of coilsWhat is the principle of wire charging? What is the farthest distance? '> How does wireless charging work? What is the farthest distance?
The principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which can ensure that there is no exposed conductive interface, which can not only save the messy transmission line between the equipment, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
Wireless charging technologyThe realization principle of the technique is electromagnetic induction, magnetic field resonance, radio wave, etc. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
Test results show that the wireless transmission distance is about 15 centimeters, but Fujitsu says that wireless transmission distance can eventually be achieved several meters. It should be pointed out that the further away from the device, the more power lost in transmission. Fujitsu's system is similar to technology developed by Witricity, an American company, which also uses magnetic resonance to transmit powerThe transmission distance can reach several meters.
