Abstract
The utility model relates to a variable light device of a locomotive light. A circuit consists of a trigger signal generator, a shaper, a unidirectional triggering diode, a driving circuit and a relay. The utility model can automatically change the near-far light according to the change of the automobile speed, relieves the operation strength, and improves the safety.
Description
The utility model relates to a kind of self-propelled vehicle device for changing light, especially changes according to the motor vehicle speed speed, automatically the device for changing light of the nearly lamp far away of conversion.
At present, known self-propelled vehicle device for changing light adopts manually or pin is stepped on operation, can not change the nearly lamp far away of automatic conversion according to speed of a motor vehicle speed.
The purpose of this utility model provides a kind of device for changing light, can change according to speed of a motor vehicle speed on the basis of original artificial change light, increases the function of the nearly lamp far away of automatic conversion.
The purpose of this utility model is achieved in that trigger signal generator, dresser, unidirectional diac, driving circuit, relay are electrically connected in proper order.The relay fixed end is connected with manual Dim Dimmer lamp mouth far away, and normally closed contact is connected with low beam, and open contact is connected with lamp far away.Trigger signal generator is formed by being arranged on the magnet of transmission shaft rotation and the induction coil close with it, when the energizing signal of its generation is accelerated to reach certain intensity with the speed of a motor vehicle, after the dresser shaping, cause unidirectional diac conducting, trigger driving circuit to relay input service voltage, normally closed contact disconnects, and low beam goes out, the open contact closure, lamp far away is bright.When energizing signal slows down when dropping to certain value with the speed of a motor vehicle, unidirectional diac stop conducting, driving circuit stop to relay transportation work voltage, and open contact disconnects, and lamp far away goes out, the normally closed contact closure, and low beam is bright.The motor generator output voltage can reflect the speed of a motor vehicle indirectly, and drive axle-free and nearly lamp far away are by the self-propelled vehicle of electrical generator direct supply, and energizing signal can be obtained by generator output end.
Owing to adopt such scheme, the nearly lamp far away of self-propelled vehicle can change automatic conversion according to the speed of a motor vehicle, realizes that the low speed low beam is bright, and lamp at a high speed far away is bright.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is first embodiment circuit block diagram
Fig. 2 is second embodiment circuit block diagram
Fig. 3 is a trigger signal generator
Among the figure 1, low beam 2, lamp 3 far away, dresser 4, potential device 5, unidirectional diac 6, driving circuit 7, relay 8, voltage stabilizer 9, with permanent magnet 10, the induction coil of transmission shaft rotation
In Fig. 3, electromagnetic induction coil (10) is because magnet (9) produces energizing signal with the transmission shaft rotation.
In Fig. 1, shown circuit is applicable to nearly lamp power supply far away by the self-propelled vehicle that provides with automobile battery, and dresser (3) is connected with electromagnetic induction coil (10).
In Fig. 2, shown circuit is applicable to nearly lamp power supply far away directly by the self-propelled vehicle of generator powered, and dresser (3) is in parallel with taillight.
In Fig. 1, Fig. 2, voltage stabilizer (8) input end is in parallel with taillight, and mouth is connected with driving circuit (6).Relay (7) fixed end is connected with manual Dim Dimmer lamp mouth far away, and normally closed contact is with manually Dim Dimmer low beam mouth is in parallel.
In Fig. 1, Fig. 2, except that the difference of energizing signal source, all the other principles are identical.Potential device (4) is used for adjusting the energizing signal after dresser (3) shaping, when self-propelled vehicle accelerates to when needing low beams (1) to become lamp far away (2), energizing signal reaches triggering intensity, unidirectional diac (5) conducting, trigger driving circuit (6) to relay (7) input service voltage, make normally closed contact disconnect the open contact closure, consequently low beam (1) goes out, and lamp (2) far away is bright.When self-propelled vehicle slowed to a certain degree, energizing signal died down, and can not cause the conducting of unidirectional triggering diode, driving circuit (6) stops to relay (7) input service voltage, makes open contact disconnect the normally closed contact closure, lamp (2) consequently far away goes out, and low beam (1) is bright.
Claims (1)
- A kind of self-propelled vehicle automatic device for changing light, it is characterized in that: the relay fixed end is connected with manual Dim Dimmer lamp mouth far away, normally closed contact is connected with low beam, open contact is connected with lamp far away, when the speed of a motor vehicle reaches certain speed, unidirectional diac is subjected to trigger signal generator or generator output end voltage triggered and conducting causes driving circuit to relay input service voltage, and the control low beam is changed to lamp far away; When the speed of a motor vehicle was lower than certain speed, unidirectional diac triggered and stops, the relay recovery original state, and lamp far away converts low beam to.
