Embodiment

The application installing of a delay circuit assembly 1 that is provided for the utility model most preferred embodiment is provided as shown in Figures 1 and 2, this delay circuit assembly 1 has an input group 101 and an output group 102, this input group 101 is series at a mains switch 2, this output group 102 is parallel to a light fixture 3, and these mains switch 2 may command are switched an AC power 20 conductings or by inputing to this delay circuit assembly 1; Please cooperate Fig. 3 and Fig. 4 reference, this delay circuit assembly 1 is to have a rectification circuit 11, circuits for triggering 12, a timing circuit 13 and an output circuit 14, wherein:

This rectification circuit 11 has one and exchanges an end group 111 and a dc terminal group 112, mainly in order to this AC power 20 is handled through rectification and voltage stabilizing, be made of several capacitors C1, C2 and diode D1, Z1 as present embodiment provide, it is required with the running that this timing circuit 13 is provided to be equivalent to this long-pending long-pending voltage of receiving of receiving diode Z1 from 112 outputs of this dc terminal group.

These circuits for triggering 12 are mainly the function of transmission electric potential signal, constitute by two resistor R 1, R2 as present embodiment provide, and between two these resistor R 1, R2, has a signal end group 120, this two resistor R 1, R2 electrically connect this input group 101, in the time of can responding to these mains switch 2 conductings produce corresponding to the voltage quasi position of input group 101 and in this signal end group 120 corresponding partial pressure potential arranged.

This timing circuit 13 mainly is made of a microprocessor 130, has a power end group 131, an one trigger end group 132 and a control end group 133, this power end group 131 electrically connects the dc terminal group 112 of this rectification circuit 11, this trigger end group 132 electrically connects the signal end group 121 of these circuits for triggering 12, the voltage quasi position that these microprocessor 130 these trigger end groups 132 of induction are received, send a control signal in this control end group 133, when the current potential of this microprocessor 130 these trigger end groups 132 of induction after meeting specific logical condition, then start timing controlled and be maintained at and send this control signal in the time of delay to limit this control end group 133.

This output circuit 14 has the characteristic of exportable AC power, therefore can be constituted by the transistor component that power supply stream two-way circulates, as the supplier of institute in the present embodiment is a two-way thyristor 140, the lock end of this two-way thyristor 140 is by being electrically connected the control end group 133 of this timing circuit 13 by a resistor R 3, these two-way thyristor 140 inductions then can transmit above-mentioned AC power 20 by these output group 102 outputs after the control signal that this control end group 133 is sent.

Therefore in the side circuit running, then have following functional status because of these mains switch 2 conductings or the operation that ends:

When this mains switch 2 is in cut-off state, this timing circuit 13 promptly can't obtain enough direct current operative power sources, but and can't send the electric current and voltage of this two-way thyristor 140 of conducting from this control end group 133, so this output group 102 equally can't the output AC operating power for this light fixture 3 of conducting.

When this mains switch 2 is in conducting state, 20 of AC power provide direct current operative power source in this timing circuit 13 after these rectification circuit 11 rectifications and voltage stabilizing, make this timing circuit 13 be maintained at an armed state, and partial pressure potential is arranged in these trigger end group 132 inductions, but thereby trigger the control signal that this control end group 133 is sent the electric current and voltage of this two-way thyristor 140 of conducting, so can be in these output group 102 output AC operating powers for this light fixture 3 of conducting.

When this mains switch 2 when the conducting state switches to cut-off state, though changing timing logics that the current potential of the signal end group 120 of these circuits for triggering 12 can start in this microprocessor 130 judges, right this rectification circuit 11 continues to be discharged by this capacitor C2, be lower than this and long-pending receive diode Z1 long-pending when receiving voltage when being discharged to, 13 of this timing circuits can't obtain direct current operative power source, this control end group 133 that is stop to send control signal, thus by the running of this output circuit 14 and no longer the output AC operating power for this light fixture 3 of conducting.

When this mains switch 2 is still kept when promptly switching back conducting state again under the normal dc operation in above-mentioned this timing circuit 13, timing logics in this microprocessor 130 then are controlled in and stop this control end group 133 after this time of delay and send this control signal, therefore can be after the user carries out above-mentioned continuous change action, in this time of delay, keep these output circuit 14 output AC operating powers for this light fixture 3 of conducting, back just fully by the output of AC power.

This delay circuit assembly 1 provided by the utility model is in response to the handover operation that cooperates as this mains switch 2, so this delay circuit assembly 1 all can be reached the purpose of switching delay with the circuit module of other similar switching circuit, so does not limit the device architecture that this delay circuit assembly 1 is separated with mains switch 2 that proposes as present embodiment.

The above only is a preferable possible embodiments of the present utility model, changes so use the equivalent structure that the utility model specification and claim do such as, ought to be included in the claim of the present utility model.
