Summary of the invention

The purpose of this utility model is, at the problems referred to above, proposes a kind of file cabinet indoor light automatic control equipment, and, cost easy to use to realize hangs down and the good advantage of fail safe.

For achieving the above object, the technical solution adopted in the utility model is: a kind of file cabinet indoor light automatic control equipment comprises power supply VCC, mains switch K1 that is electrically connected successively and a plurality of lighting sub loops that are arranged in parallel; In described a plurality of lighting sub loops, first lighting sub loop comprises the first bulb L1 and the first gate controlled switch K2 that is connected between mains switch K1 and the ground.

Further, the structure of the gate control switch in described a plurality of lighting sub loop is identical, each gate controlled switch comprises push rod 1, diaphragm 2, housing 3, binding post 4, return spring 5, fixed contact 6 and armature contact 7, be embedded with binding post 4 on the bottom surface of described housing 3, the top of described binding post 4 is provided with fixed contact 6, the bottom of described housing 3 inner chambers is provided with return spring 5, be provided with armature contact 7 above the described return spring 5, the upper end of described armature contact 7 is provided with diaphragm 2, is connected with push rod 1 above the described diaphragm 2.

The file cabinet indoor light automatic control equipment of each embodiment of the utility model, by a plurality of lighting sub loops are connected in parallel on the power supply, and independently gate controlled switch is set in each lighting sub loop, when opening single cabinet door, corresponding gate controlled switch closure, lighting sub loop closure in this cabinet door for this file cabinet provides illumination, thereby has reduced use cost; And the mains switch of all lighting sub loops of may command is set, guarantee the safe in utilization of entire circuit and made things convenient for the circuit maintenance; Use inconvenience and defect of high cost in the prior art thereby can overcome,, cost easy to use to realize hangs down and the good advantage of fail safe.

Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the utility model.The purpose of this utility model and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Description of drawings

Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the electrical principle schematic diagram according to the utility model file cabinet indoor light automatic control equipment;

Fig. 2 is the structural representation according to gate control switch in the utility model file cabinet indoor light automatic control equipment.

In conjunction with the accompanying drawings, Reference numeral is as follows among the utility model embodiment:

The 1-push rod; The 2-diaphragm; The 3-housing; The 4-binding post; The 5-return spring; The 6-fixed contact; The 7-armature contact.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

According to the utility model embodiment, as depicted in figs. 1 and 2, provide a kind of file cabinet indoor light automatic control equipment.

As shown in Figure 1, present embodiment comprises power supply VCC, mains switch K1 that is electrically connected successively and a plurality of lighting sub loops that are arranged in parallel; In a plurality of lighting sub loops, first lighting sub loop comprises the first bulb L1 and the first gate controlled switch K2 that is connected between mains switch K1 and the ground.

For example, three lighting sub loops can be set, second lighting sub loop comprises the second bulb L2 and the second gate controlled switch K3 that is connected between mains switch K1 and the ground, and the 3rd lighting sub loop comprises the 3rd bulb L3 and the 3rd gate controlled switch K4 that is connected between mains switch K3 and the ground.

Particularly, the first gate controlled switch K2 controls the first bulb L1, second gate controlled switch K3 control bulb L2, the 3rd gate controlled switch K4 control bulb L3.Like this, as long as open the door of any file cabinet, gate controlled switch all can be connected the lighting sub loop of bulb in this file cabinet, and bulb is lighted; When the door of file cabinet was closed, gate controlled switch then can disconnect the lighting sub loop of bulb in this file cabinet, and bulb is extinguished, and has saved the energy, thereby has reduced use cost; And the mains switch K1 that is provided with, deenergization when next can improve the fail safe of use, and makes things convenient for the circuit maintenance.

As shown in Figure 2, the structure of the gate control switch among Fig. 1 in each lighting sub loop is identical, each gate control switch comprises push rod 1, diaphragm 2, housing 3, binding post 4, return spring 5, fixed contact 6 and armature contact 7, be embedded with binding post 4 on the bottom surface of housing 3, the top of described binding post 4 is provided with fixed contact 6, the bottom of described housing 3 inner chambers is provided with return spring 5, be provided with armature contact 7 above the described return spring 5, the upper end of described armature contact 7 is provided with diaphragm 2, is connected with push rod 1 above the described diaphragm 2.
