The time relays KT1 and KT2 can set time delay time according to actual conditions, when the time relays KT1 and KT2 reach the set time delay time, the time relays KT1 and KT2 normally-closed contacts KT1-1 and KT2-1 which are connected with coils of the intermediate relays KA1 and KA2 in series are disconnected, so that the intermediate relays KA1 or KA2 are powered off, the normally-open contacts KM1-1 or KM2-1 of the contactors KM1 and KM2 are restored to a normally-open state, and the lighting circuit is powered off.

A plurality of manual position loops and automatic position loops can be controlled through a time controller KTZ1, the manual position loops are respectively controlled with a lighting device, and the automatic loops are respectively provided with a lighting device delay control circuit. When a certain loop does not need to use the lighting device, the control switch is set to be in an off state, and the normal work of other manual position loops and automatic position loops is not influenced; when a certain lighting device needs to be used beyond the normal lighting time of the automatic power-off of the lighting device, the delay switch arranged in the corresponding automatic position loop is pressed, at the moment, the lighting device starts to work, and when the working time reaches the delay time arranged in the delay control circuit, the lighting device is automatically powered off. Referring to fig. 3, L1-1, L2-1, L3-1 and L4-1 all represent lighting devices, and L9-1 represents an air conditioning device, and a lighting time control circuit can be set according to actual conditions, so that the diversity of the lighting devices is realized, the lighting devices work more humanized, and power resources are saved.

The second embodiment is implemented according to the following principle: the time controllers KTZ1 and KTZ2 are set to the operating time and the off time of the lighting device and the air conditioner, respectively, in accordance with actual conditions. When the preset time for the air conditioner to work is reached, the air conditioner starts to work; and when the preset time for stopping the air conditioner is reached, the air conditioner is automatically powered off to stop working.

During normal working days, the control switches SB1, SB2 are pressed, and when the preset lighting device on time is reached, the manual position loop is conducted, so that the lighting loop starts to work.

The time controller KTZ1 controls a plurality of manual bit loops and automatic bit loops. During normal working days, the plurality of control switches SBn are pressed so that the manual bit circuit is turned on when a preset lighting device on time is reached, and the lighting circuit starts to operate.

When the time for disconnecting the lighting device is preset, the normally open contact KTZ1-1 of the time controller KTZ1 in the manual loop is recovered to be normally open from the normally closed state, and the plurality of manual position loops are all powered off, so that the corresponding lighting loops are powered off, and the automatic position loops are switched on.

When some lighting device needs to be used beyond the normal working time of the lighting device, the time delay switch in the automatic position loop is pressed, and the lighting loop starts to work. When the time relay KTn reaches the set delay time, the lighting circuit is powered off, so that the lighting device is automatically powered off.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
