The control strategy answered, specifically, can preset the number that user triggers contact switch in specified time is that i.e. 3 contact switch are
At On-Off-On 3 times, corresponding to control strategy be " extinguish LED lamp bead simultaneously keep WIFI trunk module working condition "；Into
One step, when WIFI trunk module 40 receives the switch panel state for the LED lamp that alternating current state monitoring module 30 monitors
When for default specified time internal trigger contact switch number being 3 times, then control strategy is determined according to the switch panel state, and to
LED drive module 20 exports corresponding control signal, in the case where rectification filtering module 10 persistently exports the first direct current
It controls LED drive module 20 and stops driving work, realize in the case where not influencing WIFI trunk module 40 and working to LED lamp bead
Extinguished.
As another example, firstly, the corresponding control strategy of switch panel state of default LED lamp, specifically, in advance
If then corresponding control strategy is to keep WIFI trunk module 40 when the switch panel state of LED lamp is " On-Off-On "
Working condition, and lightening LED lamp pearl；It is when the switch panel state of LED lamp is " On-Off-On-on/off ", then corresponding
Control strategy is the working condition for keeping WIFI trunk module 40, and extinguishes LED lamp bead；In this way, when WIFI trunk module 40 connects
The switch panel state of LED lamp is received, control strategy can be carried out really according to the switch panel state of the LED lamp received
It is fixed, to send corresponding control signal to LED drive module 20, to control it.
As another example, when the switch panel of LED lamp is set as double control switch, it is assumed that one of them, which is switched, is
A switch, another switch be B switch, then combine two switch caused by combination control signal can there are many (for example,
AAB, ABA, AAA, ABB etc.), it is possible to further obtain user's trigger switch by the switch panel state of monitoring LED lamp
Assembled state, and then corresponding control strategy is judged by the assembled state of user's trigger switch, and according to the control strategy
Corresponding control signal is exported to control LED drive module 20.
Which kind of therefore, regardless of control strategy used, can be can be achieved with by easily switch control logic in not shadow
The extinguishing of LED lamp bead is controlled under the premise of ringing WIFI relay function, without APP control, is reduced costs, it is easy to operate,
Substantially increase user experience.
In conclusion the driving circuit of LED lamp according to an embodiment of the present invention, by rectification filtering module to input
Electric main carries out rectifying and wave-filtering processing, and to export the first direct current, LED drive module is according to the first direct current output driving electricity
It is depressed into LED lamp bead, to drive to LED lamp bead, so that LED lamp bead is able to carry out illumination under the driving of LED drive module
Work, while voltage monitoring is carried out to the output of rectification filtering module to detect LED lamp by alternating current state monitoring module
Switch panel state, such WIFI trunk module produce the first control strategy according to switch panel state, and according to the first control
System strategy output first control signal is to LED drive module, to export the first direct current, that is, switch panel in rectification filtering module
LED drive module is controlled when closure and stops driving work, is extinguished to control LED lamp bead, while WIFI relaying power supply module will
First direct current is converted to the second direct current, powers to WIFI trunk module, to keep WIFI to relay mould when LED lamp bead is extinguished
Block works normally, and closes to control LED lamp in the case where driving circuit persistently gives electricity, and LED lamp is closed later not
Influence the realization of WIFI relay function.Therefore, the present invention can be can be completed by the simple operations to switch panel in not shadow
The extinguishing that LED lamp bead is controlled under the premise of ringing WIFI relay function, simplifies user's operation behavior, improves user experience, and nothing
The exploitation of the equal external control processing procedure sequence of APP need to be carried out, project implementation cost is saved.
