It is especially a kind of that there is the infrared and self power generation of wireless communication function the present invention relates to technical field of switch controlFormula light fixture control device of wireless.
Background technology
In the prior art, the self-power generation type light fixture controlled in wireless with wireless communication function closes the control for being mainly used in light fixtureSystem.Because radio has the characteristics of any direction propagation, the signal of some switch transmitting will be by all installed in surroundingReceiver is connected to, and is the signal of which switch transmitting to enable receiver to distinguish, it is necessary to each switch, one ID is set,Need switch that this ID is sent to receiver by radio frequency before the use, receiver stores the ID, and this process is pairingAlso action volume.This ID is included in the radio signal that switch is sent during normal control, whether receiver has been registered according to IDTo judge whether to respond the control instruction of the switch, so as to realize the control only in response to the switch matched.Pairing is usual at presentThe method taken is to set a button on the receiver, presses the states to be paired such as rear receiver entrance, receives firstID therein is extracted after control signal and stores completion pairing.As do not pressed button, then receiver operation is in normal mode, i.e.,ID in control signal judges whether to need to respond.
Aforesaid way has the drawback that：Firstth, if just there is other during receiver waits pairing signalIt is unexpected that switch have sent a control signal, and this will cause to mismatch pair, and bad removing；Secondth, usual receiver installationIn the ceiling installed in light fixture or the space of light fixture, if to match after installing, needing to dismantle after light fixture could be byThe switch on receiver is obtained, use is very inconvenient；3rd, if necessary to match after receiver installs, then need to connecingReceiving after device connects civil power can just work by by pairing button, and this easily causes user's electric shock, and security is poor.
