Description

Lighting household system based on wireless charging technology

Technical Field

The application relates to the technical field of radio, in particular to a household wireless charging and lighting system.

Background

The wireless charging technology is derived from a wireless power transmission technology, charges are transmitted in the air between a charger and equipment by utilizing magnetic resonance, and a coil and a capacitor form resonance between the charger and the equipment, so that the technology of high-efficiency transmission of electric energy is realized.

Currently, the mainstream wireless charging includes the following three types:

the first is wireless charging by magnetic induction technology, the principle of the wireless charging by the technology is Faraday's law of electromagnetic induction, electromotive force is generated by cutting a magnetic field through a conductor, the wireless charging is composed of two coils, a magnetic field is generated when alternating current is connected to a primary coil, alternating current is induced by a secondary coil due to the existence of an alternating magnetic field, and the most common application is a transformer. The technology has the advantages of high charging efficiency (the charging efficiency of the mobile phone is more than 80%), and the defects of short charging distance, need of being tightly attached to the transmitting plate for charging, and need of being aligned during charging to charge, which represents three stars, Nokia, Sony and the like.

The second is wireless charging by magnetic resonance technology, that is, the resonance device is used, the transmitting end and the receiving end reach the same frequency to achieve magnetic field resonance, and energy exchange is satisfied. Compared with the magnetic induction technology, the technology has the advantages that the charging distance is long (the charging conversion rate of a mobile phone can reach 7cm at present), the charging area is large, the mobile phone can be charged at any time, the charging efficiency is slightly low, the highest charging efficiency is about 70% at present, and the factory represents high-pass, Witricity and micro goose technologies.

The third is radio frequency technology wireless charging, and the technology is very attractive in China or abroad. The technology uses a space electric field as a medium, and an energy transmitting plate and a receiver are regarded as two polar plates of a capacitor. Under the action of an alternating current field, alternating current flows through two polar plates of the capacitor, so that wireless transmission of electric energy is realized. The greatest advantage of the rf technology is the long charging distance, but the disadvantage is also very obvious. One is radiation and the other is very low conversion efficiency.

The smart home is a living environment, a residence with a smart home system installed on a residence as a platform, and the process of implementing the smart home system is called smart home integration. The method has the advantages that a house is used as a platform, facilities related to home life are integrated by utilizing a comprehensive wiring technology, a network communication technology, an intelligent home-system design scheme safety precaution technology, an automatic control technology and an audio and video technology, an efficient management system of home facilities and family schedule affairs is constructed, home safety, convenience, comfortableness and artistry are improved, and environment-friendly and energy-saving living environment is realized. The smart home needs to be understood in two parts, namely smart home and home. The household is various devices for people to live; the intelligent home is the key point that the intelligent home should be highlighted, automatic control management should be achieved, manual operation control is not needed, the use habits of current users can be learned, and the requirements of people can be met.
