Description
Technical field
The present invention is a kind of multi-function desk lamp that the electronic product wireless charging is provided, and relates to electronic product wireless charging field.
Background technology
Wireless charger is the equipment that utilizes electromagnetic induction principle to carry out contactless charging to the electric equipment products of receiving terminal, usually is applied to the electronic products such as mobile phone, MP3, digital camera.The end that transmits and receives at wireless charging respectively has an inductance coil, transmitting terminal connects wired power generation high-frequency alternating magnetic field, the receiving terminal coil picks up the electromagnetic energy of transmitting terminal by magnetic Field Coupling, and through over commutation and filtering, charges the battery with fixing DC voltage and electric current.The wireless charger of selling on the existing market is independently charging equipment, need to use independently power supply adaptor, and also can there be the power line of a Payload attach fitting and supply socket in independent external power supply.Such design often can be complained by the user and do not bring attractive in appearance, experience easily, does not sensuously also realize real wireless power.
The present invention adopts desk lamp to combine with the wireless charging technology, considers that mainly desk lamp generally is one of electric equipment products the most frequently used in the family, and the placement location of desk lamp, such as desk or bedside cupboard, also is the most recurrent places such as cell-phone charging.Therefore wireless charging module is combined with desk lamp, can create and a kind ofly both can be used for illumination, also can be the Multifunction product of the electronic product wireless chargings such as mobile phone, can greatly promote convenience and the ease for use of wireless charging technology, be expected to overcome the marketing bottleneck of present wireless charging product, become one of major product form of following wireless charging product.
Summary of the invention
The object of the invention is to propose a kind of desk lamp that the electronic products such as mobile phone carry out wireless charging that can be.This desk lamp both can be the electronic product wireless chargings such as mobile phone, can use as lighting apparatus again.
Technical scheme of the present invention is: comprise lamp bracket, base, power line and lighting source, it is characterized in that at the built-in wireless charging module that wireless charging can be provided for the receiving device with energy pickup model of described base.By the wireless power transmission module on Desk lamp feet to realize that mobile phone etc. is realized wireless charging with the electronic product of radio energy receiving terminal.
Wireless charger of the present invention comprises a radio energy transmitting coil, a phase magnet at least, a transmitting terminal control circuit board, and the magnetic material layer that is used for electromagnetic shielding between transmitting coil and control circuit board.Because transmitting coil and transmitting terminal control circuit board need to be embedded in the less space of Desk lamp feet, so transmitting coil and transmitting terminal control circuit board need close together, even the design of being close to.Between transmitting coil and transmitting terminal control panel, embed the shielding material of one deck soft magnetism among the present invention.
Such design mainly is to consider that the coupling that induction wireless power transmission is based on external electromagnetic field carries out, there is stronger electromagnetic field at the transmitting coil annex, this not only can affect the normal operation (being equivalent to electromagnetic interference) of some components and parts on the control panel, also exists electromagnetic leakage to cause potential harm to health of human body simultaneously.Therefore, when the design of screen layer can guarantee the control circuit normal operation, also can eliminate the impact that electromagnetic radiation causes health of human body.
The present invention has obvious positioning mark and phase magnet at the base of desk lamp, in the time of near receiving terminal is placed on positioning mark, can accurately locate by the suction of phase magnet.Owing to adopt electromagnetic induction principle to carry out wireless power transmission, its operating distance less (several millimeters generally only being arranged to centimetre).If transmitting terminal coil and receiving terminal coil can not accurately on time, may cause wireless charging module not start, or efficiency of transmission obviously reduce.For this reason, the present invention is printed with obvious positioning mark at upper surface, be designed with phase magnet in the susceptor surface inboard, such design can guarantee, when the user is placed on the Desk lamp feet receiving device near the positioning mark, can receiving terminal and transmitting terminal accurately be located by the suction of phase magnet.
After desk lamp power line of the present invention was introduced Desk lamp feet, through a public rectification and filtration module, output DC was respectively the power supply of desk lamp and wireless charging module.Such design can be merged the power control circuit of desk lamp and the circuit of wireless charging module, reduces the quantity of components and parts and circuit board, reduces the space hold of control circuit, reduces the Material Cost of product.
Desk lamp of the present invention, its illumination functions and wireless charging function can independently be controlled, and wireless charging function still can work when namely desk lamp extinguished.Consider desk lamp only at night or daytime the indoor illumination intensity deficiency situation under just be used, electrical equipment charging then is contingent thing all at any time, therefore, the present invention has adopted independently illumination and wireless charging function and has controlled.Wherein throw light on by the switch control that is positioned on the Desk lamp feet, and wireless charging function adopts the design of load identification, can arrive the existence of load by Auto-Sensing, and start main control circuit, begin receiving device is charged.
Desk lamp with wireless charging function of the present invention is provided with indicator lamp at its base.When wireless charging function starts, but the duty of indicator lamp display radio charging.Such design mainly is the facility of considering that the user uses, can make the user can clearly know the state of present charging.
Compare prior art, the present invention is embedded into wireless charging module in other the electronic product, with the input as wireless charging module of the power supply of these products self, this " stealth " embedded design, can eliminate loaded down with trivial details, the inconvenient sensation that the user feels when using free-standing charger, greatly promoted convenience and the ease for use of electronic product charging, saved simultaneously the space, the user experiences and also can be significantly improved.
