Abstract
The utility model discloses a control circuit for the front dome lamp of a vehicle. The control circuit comprises a left lamp, a right lamp, a gate controlled switch, a left lamp switch and a right lamp switch; the gate controlled switch, the left lamp switch and the right lamp switch adopt monopole double throw switches; the gate controlled switch is connected with a gate controlled signal; the common point of the gate controlled switch is respectively connected with the throw points of the left lamp switch and the right lamp switch; the common points of the left lamp switch and the right lamp switch are connected with one electrode of a power supply; and the other throw points of the left lamp switch, the right lamp switch and the gate controlled switch are connected with the other electrode of the power supply. The control circuit has the advantages that the structure is simple and practical; the use of the front dome lamp of the vehicle can be directly controlled through the circuit; and the turning on/off of the front dome lamp is ensured.
Description
Technical field
The utility model discloses a kind of control circuit that is used for automobile with preceding ceiling light.
Background technology
The preceding in use ceiling light of automobile is as room light, very important effect is arranged at night, need to insert key into the car such as the door of just driving, if needing roof lamp to help chaufeur without light, car seeks key hole outward, need read thing when perhaps stopping at night in car, ceiling light helps illumination before also needing, and the preceding ceiling light of car is being controlled the switch in skylight, need turn on light when driving door, just need control lamp.
Summary of the invention
The purpose of this utility model is to provide the control circuit of a kind of automobile with preceding ceiling light, it to automobile before ceiling light control to reach when driving door and turn on light, the effect of turning off the light when closing car door, and lamp is opened when opening switch.
The technical scheme that realizes the utility model purpose is as follows:
Automobile is with the control circuit of preceding ceiling light, it comprises left lamp, right lamp, door contact, left light switch, right light switch, door contact, left light switch, right light switch are single pole double throw switch, door contact is connected with gate-control signal, the common point of door contact links to each other with a throwing point of left light switch, right light switch respectively, the common point of a left side light switch, right light switch extremely links to each other with one of power supply, and another of another throwing point of left light switch, right light switch and door contact and power supply extremely links to each other.
The common point of described door contact links to each other with the pass throwing point of left light switch, right light switch respectively.
The negative of opening throwing point and power supply of described left light switch, right light switch and door contact connects.
The common point of described left light switch, right light switch links to each other with the positive pole of power supply.
Adopted such scheme, gate-control signal makes its common point be connected with opening throwing point or close throwing point for door contact provides signal, thereby makes left lamp and right lamp connection circuit and illuminate, and left light switch, right light switch directly can be controlled illuminating of left lamp and right lamp and close.Benefit of the present utility model is simple and practical, can be by the use of ceiling light before this circuit direct control automobile, before guaranteeing the illumination of ceiling light with close.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1, door contact, 11, gate-control signal, 2, left light switch, 21, left lamp, 3, right light switch, 31, right lamp.
The specific embodiment
As shown in Figure 1, automobile is with the control circuit of preceding ceiling light, it comprises left lamp 21, right lamp 31, door contact 1, left light switch 2, right light switch 3, door contact 1, left light switch 2, right light switch 3 are single pole double throw switch, door contact 1 is connected with gate-control signal 11, the common point of door contact 1 links to each other with the pass throwing point of left light switch 2, right light switch 3 respectively, the common point of left side light switch 2, right light switch 3 links to each other with the positive pole of power supply, and the throwing point of opening of left light switch 2, right light switch 3 and door contact 1 links to each other with the negative pole of power supply.When gate-control signal 11 provides the driving gate signal, the common point of door contact 1 with open throwing point and be communicated with, this moment left lamp 21, right lamp 31 circuit communication, and begin to throw light on, if gate-control signal 11 provides when closing gate signal, the common point of door contact 1 with open throwing point and disconnect, this moment left lamp 21, right lamp 31 circuit breaker and close illumination, behind closing of the door, direct control left side light switch 2 can be turned on left lamp 21 and right lamp 31 with right light switch 3.
