1, first of all, long press the Amazon clock wireless charging audio power button to start, enter the power state, in the power state, long press the power button to enter the OFF standby state. Second, in the standby state, short press the power button. Finally, the clock will appear, and the hour hand part begins to blink, press the add or subtract key to adjust the hour hand, you can adjust the Amazon clock wireless audio charging time.
2, first click the setting, the key "Enter the time setting state, while the year, flicker. You can press up or down, the key to modify the year, change to return to the settingDamaged, may need to repair or replace the charging port oh. If the above methods can not solve the problem, it may be the battery inside the lamp is faulty.
Do you find it super annoying that the lamp can't be charged? Don't worry, it's probably just a small problem with the power switch or the booster board! Follow us to troubleshoot, easily solve the power switch failure try the two pins of the short-circuit switch, if the light is normally lit up, it is the problem of the key switch! If it's not, we might need to look at the back circuit.
The lamp can not be charged into the power may be a failure of the power switch, or it may be a booster plateIf there is a fault, you can use a multimeter to measure and check. If the cable is exposed or broken, the lamp will not be charged. You need to find a similar charging cable to check whether it can be charged normally.
Why the charging lamp is not charged this is probably the following reasons for the fault there are roughly two reasons: charging lamp power switch failure. You can short-circuit the two pins of the switch to check whether the indicator light can light up normally. If it can light normally, it indicates that the key switch is damaged and can be replaced. If no, the fault is in the subsequent circuit. The booster plate is faulty. The detection of the booster plate fault can only be measured by a multimeter.
The table lamp can play music in the following steps: Turn on the Bluetooth function of the Xiaomi table lamp: On the control panel of the Xiaomi table lamp, find the Bluetooth icon, click to enter the Bluetooth setting interface, and turn on the Bluetooth switch. Connect your phone to the Xiaomi table lamp: Turn on the Bluetooth function of your phone, search for available devices, find the Bluetooth name of the Xiaomi table lamp, and click Connect. Play music: After the connection is successful, select the music to play on your phone and click the Play button.
Open Bluetooth button, handBluetooth on, pairing successful. Bluetooth technology is an open global specification for wireless data and voice communication. It is a special short-range wireless technology connection based on low-cost short-range wireless connection to establish a communication environment for fixed and mobile devices. Bluetooth enables some of today's portable mobile devices and computer devices to connect to the Internet without the need for a cable and to access the Internet wirelessly.
Connect the mobile phone to the WiFi network, download and install and open the Mijia APP. Register and log in the Mi APP Xiaomi account, click the plus button in the upper right corner of the APP homepage. On cueTurn on the Bluetooth switch of the mobile phone and select Mijia table lamp from the device list. Insert the slim into the reset hole in the base of the lamp for 5 seconds and let go when the lamp begins to breathe.
First of all, mobile phones and car Bluetooth devices should establish a pairing relationship. Turn on the Bluetooth function of the mobile phone and the car Bluetooth device respectively, and set the Bluetooth Settings of the mobile phone to be visible to all. Then search the Bluetooth device in the mobile phone, and select the pairing connection after finding it. The pairing password is 0000, and the connection is successful after the pairing is completed.
", enter the device scanning screen, and click scan device. The Xiaomi lamp will appear below477b This device, this is the millet lamp that you want to connect. Click on the table lamp, will jump to the interface connected to the wireless network, enter the commonly used wifi name, and enter the password.
1, the circuit schematic diagram of the rechargeable LED lamp. The circuit is shown in the figure above. After the power supply is turned on, the AC 220V voltage is reduced and current limited by the capacitor C1, the rectifier bridge rectifier and the capacitor C2 filter, and a DC voltage is generated to charge the 4V battery through the diode VD. The charging current of the battery is mainly caused byCapacitor C1 determines that when C1 uses a 1μF capacitor, the charging current of the battery is about 69mA.
2, charging desk lamp is a lamp that uses light energy as an energy source. It usually contains a solar panel, which is able to convert sunlight into electricity. Solar panels can also store electrical energy in lithium-ion or lead-acid batteries for use when the sun is not visible. When the lamp needs to use the light, the battery will power the bulb. This allows you to use lights without mains power.
3, LED table lamp circuit as shown in the following figure, workThe working principle is as follows: ● Lighting process: When the normal light is not on: C1 is charged by B (B is the lead battery voltage) through RRR3 to B, and the light is not on.
4, led charging lamp working principle LED (LightEmittingDiode) charging lamp works by converting electrical energy into light energy. When a current flows through an LED, electrons in one of the semiconductor materials (usually P-type) are transferred to holes in the opposite N-type material. In this process, the electrons give off energy, and this energy is released as light.
5. Take the common charging small lamp on the market as an example. During the charging period, the 220V AC is converted into pulsating direct current to charge the battery, and the better use of constant current and constant voltage to charge the battery; During discharge, the battery converts electrical energy into LED luminous light energy, and the working current is pure DC current.
Micro storage battery charging method Now most of the charging desk lamps use micro storage batteries. This kind of battery can't lose or overcharge. So, you can charge directly, don't worry about overcharging orThe problem of losing power. The first charge The first charge takes 4-6 hours, and when you feel the brightness decreases, you can charge it in time. With the right way of charging, you can eliminate the memory effect and make the lamp's brightness last as long as new.
If the charging lamp is used while charging, it will gradually reduce the charge storage of the rechargeable battery and may burn the original, and it is not necessarily burned as long as you use it like that, but it is risky. Do not use while charging If the lamp is used normally now, do not worry about it. Next time, pay attention not to use while charging, which is not safe and affects the life of the lamp.
When charging, the lamp will convert 220V alternating current into pulsating direct current to charge the battery. This charging method is simple and easy to use, and is suitable for most small desk lamps. Constant current, constant voltage technology More advanced small desk lamps use constant current, constant voltage technology to ensure that the battery is properly charged. This charging method can better protect the battery and extend the service life of the battery.
can be used while charging, but it is not recommended to use it this way, so that the lamp life is easy to reduce, sometimes when charging and using, there will be a clap at the power source, and it is easy to burn the lamp plug. Side-charging is not recommendedElectric side use do not charge while using, electric lamp will live a long life, pro test, found that while charging while using the lamp is not bright.
First of all, the charging desk lamp you newly bought home may also be not bright, then this time may be because the charging desk lamp has no electricity, if the charging desk lamp is charged or not bright, then it may be because the switch is bad, or the reason why the welding wire original fell off. And if we use it at the same time, it will break.
Oakes charging small lamp is not bright for the following reasons the battery is out of power: if it is not charged for a long time, the battery will run out of power, resulting in the lamp can not light up normally. Poor charging: If the lamp charger is poorly connected or there is a problem with the charging interface, it will also leadThe charge is not successful, and then the lamp cannot light up normally. Line failure: If the line between the charger and the battery fails, it will also cause the lamp to not work properly.
