Based on above-mentioned all embodiments, the operation principle that circuit tested discharge time by light fixture is as follows:
When light fixture does not discharges, phototriode Q1 does not sense illumination, and phototriode Q1 ends.With
Time, switching tube Q2 ends, and therefore the electronic coil of relay K 1 must not be electric, and the normally closed of relay K 1 is opened
Pass remains closed.Thus, the timing end 1 of timer DH48S and and timing end 4 by relay K 1
First normally closed switch keeps connecting, according to the catenation principle of timer DH48S, timing end 1 and timing end 4
During connection, timer DH48S is not-time.Meanwhile, reminding module 130 is normal by the second of relay K 1
