Today to share the daily knowledge of wireless charge production, which will also explain the introduction of wireless charger products, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>1, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the phone without wire connection.
2, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmissionTechnology is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the electrical device, the device uses the received energy to charge the battery, and at the same time for its own operation. 3, 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.
4, wireless charging refers to the charging without the traditional charging power cord connected to the terminal device that needs to be chargedEnjoy charging fun on appliances.
Mi Civi 4 Pro supports wireless charging. The design of this mobile phone has taken into account the needs of users for wireless charging, and is equipped with the corresponding wireless charging receiving module, so that it can be compatible with wireless charging equipment and normal use. Wireless charging technology has become more and more popular in the mobile phone industry in recent years, which provides users with more convenient and flexible charging methods.
First, open "Settings", go to "Battery and Performance", and look for the "wireless charging" option. If you see it, it means that your Mi 11 has wireless charging superpowers! Choose Qi standard charger Secondly, choose a wireless charger that is in line with Qi standard. Mi 11 is compatible with many brands of Qi chargers, not only can you choose the official Xiaomi model, but also explore more brand options.
The steps to use millet wireless charging are as follows: Confirm whether the mobile phone supports wireless charging function, you can view the relevant information in the Settings of the mobile phone, go to Settings, battery and performance, wireless charging, wireless charging option appears, indicating that millet wireless charging device supports wireless charging function. Get a wireless charger that supports the Qi standard.
The answer is yes. milletMany mobile phone models launched in recent years have realized the function of wireless charging, including the relatively new models such as Xiaomi Mi 10Pro and Xiaomi 11. In terms of wireless charging technology, Xiaomi's mobile phone uses the Qi standard, which means that it can be compatible with other wireless chargers that use the standard. Specifically, wireless charging is achieved by coupling the electromagnetic field between the charger and the phone.
1, this is the quality difference. TV backlighting is better designed, and lights, especially small factories, leave little margin to reduce costs. So it is easily damaged.
2, first of all, the LED wick module has high luminous efficiency. Under the same lighting needs, LED lights require lower wattage, more power saving. The luminous efficiency of the LED wick module can reach more than 100LM/W, while the luminous efficiency of the fluorescent lamp is usually about 50LM/W. Therefore, under the same brightness, the LED wick module power consumption is only half of the fluorescent lamp. Second, the LED wick module has a long service life, and it is not necessary to replace the ceiling light source frequently.
4, different manufacturers of 12V module LED models are different, If there will be differences, the actual working current may be a big difference. Conventional estimation method: The current of the low-power LED is 20mA, and the Vf is about 2V, that is, the LED in the module is 3 in series and then the resistor is used to divide the voltage limitFlow, 30LEDs are 10 groups. The total current is about 200mA (0.2A), and the power is 12x0.2A=4W. Light-emitting diode is called LED for short.
5, you can see the importance of temperature on its direct influence. In particular, it is worth mentioning that the heat balance speed of the heat dissipation material requires attention, resulting in the heat of the light source can not be effectively treated, resulting in serious light attenuation. At present, many manufacturers of high-power LED heat sink heat sink housing applications basically use different alloy aluminum materials, its thermal conductivity is different, and the heat dissipation rate of some materials is difficult to meet the working conditions of LED.
6, first, LED wick module luminous efficiency is high, the same lighting needs, LED lights need lower wattage, more power saving. The luminous efficiency of the LED wick module can reach more than 100LM/W, and the luminous efficiency of the fluorescent lamp is usually about 50LM/W, so the same brightness, the LED wick module power consumption is only half of the fluorescent lamp. Second, the LED wick module has a long service life and does not need to replace the ceiling light source often.
