Specific implementation mode
It elaborates below to the embodiment of the present invention, the present embodiment is carried out lower based on the technical solution of the present invention
Implement, gives detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
Embodiment 1
With reference to figure 1, a kind of driving circuit of toggle switch switching different conditions, including：Two groups of mutually independent LED light
Source and the one-to-one switching circuit of LED lamp source, and switched for controlling the control that the switching circuit opens or closes
skt；LED lamp source is illustrated with two groups in the present embodiment, and practical application can be three groups or more, it is only necessary to simple to increase switch
The number of circuit can.The simple replacement for belonging to the present embodiment, repeats no more.
The control switch skt has to be dialed to the one-to-one contact of the switching circuit, the control switch skt
When being electrically connected with one of contact, switching circuit corresponding with the contact disconnects；It is touched as all when control switch skt is stirred
When head is not all electrically connected, all switching circuits are all in conducting state.Therefore, a kind of switching of above-mentioned toggle switch is different
The driving circuit of state is controlling switch skt and all contacts all non-contiguously, and each paths of LEDs lamp source is corresponding
Switching circuit is all in conducting state, that is to say, that each paths of LEDs lamp source is all in illuminating state, therefore, is cut in switch position
Be not in the case where all LED lamp sources are all extinguished during changing, for the Art Museum, museum is this that lamp source is needed to be always on
Place for, just very be applicable in.
