When threshold value, wireless communication module issues charging signals to wireless power receiving module, so that wireless power receiving module is energy storage
Module charging.It is worth noting that, wireless power receiving module is to guarantee lighting module in illumination working condition at this time
Under the premise of for energy-storage module charge.
Further, when the current electric quantity that lighting module is in illumination working condition and energy-storage module is not less than on electricity
When limiting threshold value, namely the current electric quantity of energy-storage module has expired at this time, and energy-storage module is without charging.Wireless communication module at this time
Power supply signal is issued to wireless power receiving module, wireless receiving module is made to remain energy-storage module power supply to allow lighting module to protect
It holds in illumination working condition.
Further, when the current electric quantity that lighting module is not in illumination working condition and energy-storage module is lower than on electricity
When limiting threshold value, wireless communication module issues charging signals to wireless power receiving module, so that wireless power receiving module is storage
It can module charging.It is worth noting that, at this time lighting module be not in illumination working condition only indicates disconnection illuminating part input
Electric current, and illumination control circuit still can work normally.
Further, when the current electric quantity that lighting module is not in illumination working condition and energy-storage module is not less than electricity
When upper limit threshold, wireless communication module issues standby signal to wireless power receiving module, keeps wireless power receiving module
The normal work of illumination control circuit and the input current for cutting off illuminating part.
Step S3: when energy-storage module is powered to lighting module, the electricity of energy-storage module is obtained, if the electricity of energy-storage module
Lower than charge threshold, then the output power of energy-storage module, or control wireless receiving module are reduced as energy-storage module power supply.
In the present embodiment, when energy-storage module is powered to lighting module, wireless communication module obtains the electricity of energy-storage module,
If the electricity of energy-storage module is lower than charge threshold, the output power of energy-storage module is reduced, or control wireless receiving is energy storage mould
Block power supply.
Specifically, when energy-storage module is powered to lighting module, wireless communication module reads the working condition of lighting module,
And judge whether lighting module is in illumination working condition；And the electricity of energy-storage module is obtained, and judge the electricity of energy-storage module
Whether amount is lower than charge threshold.For example, charge threshold can be but be not limited to: 20% electricity, 10% electricity, 5% electricity etc..
Further, wireless communication module by reading the current or voltage of lighting module immediately, and then judges channel radio
Whether news module is in illumination working condition；And the voltage value by reading energy-storage module immediately, and filled with preset

Bluetooth or Wi-Fi are communicated with magnetic field control module, and wireless communication module sends wireless signal to magnetic field control module, control magnetic field
Molding block reduces the size of input electromagnet electric current, and then the hoverheight of lamp body is reduced to the distance range of wireless power
Interior, wireless communication module exports charging signals to wireless power receiving module again at this time, makes wireless power receiving module energy storage
Charging.
It is understood that in some embodiments, when lighting module is in illumination working condition and energy-storage module
When electricity is lower than charge threshold, it can charge while reducing the output power of energy-storage module for energy-storage module.Specifically, if lamp
The hoverheight of body in the distance range of wireless power, then wireless communication module export simultaneously low light signals to energy-storage module and
Output charging signals are to wireless power receiving module, wireless power receiving module while making energy-storage module reduce output power
For energy-storage module charging；If the hoverheight of lamp body is greater than the maximum distance of wireless power, wireless communication module exports simultaneously
Low light signals are to energy-storage module and issue wireless signal to magnetic field control module, and energy-storage module reduces output power and makes to illuminate at this time
The illumination intensity of module reduces, and magnetic field control module makes the hoverheight of lamp body drop to the distance range of wireless power
Interior, wireless communication module exports charging signals to wireless power receiving module again at this time, makes wireless power receiving module energy storage
Charging.
Further, when lighting module is in the electricity for illuminating working condition and energy-storage module higher than charge threshold, nothing
Line communication module issues power supply signal to energy-storage module, and energy-storage module is made to remain energy-storage module power supply to allow lighting module to keep
In illumination working condition.
Further, when lighting module is not in the electricity for illuminating working condition and energy-storage module lower than charge threshold,
Wireless communication module issues charging signals to wireless power receiving module, so that wireless power receiving module fills for energy-storage module
Electricity.It is worth noting that, lighting module is not in illumination working condition and only indicates the input current of disconnection illuminating part at this time, and shine
Bright control circuit still can work normally.
Further, when lighting module is not in the electricity for illuminating working condition and energy-storage module higher than charge threshold,
Wireless communication module issues standby signal to energy-storage module, and energy-storage module is made to keep the normal work of illumination control circuit and cut off
The input current of illuminating part.
In some embodiments, if the control method of above-mentioned Magnetic suspension lamp can also include: attachment base and lamp holder it
Between relative distance be greater than or equal to distance threshold, then disconnection of wireless power supply receiving module be lighting module power supply line, and

In the present embodiment, distance threshold is the critical distance of wireless power.In wireless power receiving module to lighting module
When power supply, if relative distance between lamp body and pedestal is greater than or equal to distance threshold, wireless power receiving module obtain by
The wireless power signal of wireless power transmitting module transmitting is insufficient, so that wireless power receiving module is exported to the electricity of lighting module
Stream can be gradually decrease to disappear, and wireless communication module can obtain the electric current output state of wireless power receiving module immediately at this time,
When the electric current output state for the wireless power receiving module that wireless communication module obtains occurs abnormal, wireless communication module is immediately
It sends third and controls signal to energy-storage module, powered using switching to energy-storage module as lighting module.
Wireless power is received mould by wireless communication module by the control method of Magnetic suspension lamp provided by the embodiments of the present application
The electric energy of block is distributed to as lighting module power supply and is energy-storage module charging, and can be the case where not influence lighting module power supply
It charges for energy-storage module down, and energy-storage module is used as the backup power source of lighting module to be in workable state at any time simultaneously, into
And keep the cruising ability of Magnetic suspension lamp more lasting, improve the illuminating effect of Magnetic suspension lamp, it is ensured that good user experience.
