As shown in Figure 1, be the circuit diagram of lamp control circuit one preferred embodiment of the present invention.The lamp control circuit of present embodiment comprises first electromagnetic switch, second electromagnetic switch, power supply, motor M, the first signal input part H1 and secondary signal input H2.Wherein, first electromagnetic switch and second electromagnetic switch are direct current relay, and the first signal input part H1 and secondary signal input H2 all import direct current signal.
In the present embodiment, first electromagnetic switch and second electromagnetic switch are direct current relay, and its model is preferably G2R-24-12DC.Power supply is the 12V DC power supply.
The first direct current relay K1 comprises first coil 100, first common 11, second common 21, first normally-closed contact 12, second normally-closed contact 22, first normally opened contact 13 and second normally opened contact 23; First coil 100 gets electric control first common 11 and first normally opened contact 13, second common 21 and 23 adhesives simultaneously of second normally opened contact.
The second direct current relay K2 comprises second coil 200, the 3rd common 31, the 4th common 41, the 3rd normally-closed contact 32, the 4th normally-closed contact 42, the 3rd normally opened contact 33 and the 4th normally opened contact 43; Second coil 200 gets electric control the 3rd common 31 and the 3rd normally opened contact 33, the 4th common 41 and 43 adhesives simultaneously of the 4th normally opened contact.
First common 11 is received positive source; Second common 21 is received power cathode; The 3rd common 31 is received the motor M positive pole; The 4th common 41 is received the motor M negative pole; First normally-closed contact 12 is connected with the 4th normally opened contact 43; First normally opened contact 13 is connected with the 3rd normally-closed contact 32; Second normally-closed contact 22 is connected with the 3rd normally opened contact 33; Second normally opened contact 23 is connected with the 4th normally-closed contact 42.
First coil, 100 1 end ground connection, a termination first signal input part H1; The first diode D1 is connected in parallel on the two ends of first coil 100, and plus earth; Second coil, 200 1 end ground connection, a termination secondary signal input H2; The second diode D2 is connected in parallel on the two ends of second coil 200, and plus earth.
In the present embodiment, the preferred model of the first diode D1 and the second diode D2 is IN4007, prevents that the induced current that coil produces when outage from burning coil, shields to coil.
The input signal of the first signal input part H1 is rotated in the forward signal for what the control motor M was rotated in the forward, and the input signal of secondary signal input H2 is the reverse rotation signal of control motor M reverse rotation.
When the first signal input part H1 and secondary signal input H2 all do not have input signal, at the first direct current relay K1 and the second direct current relay K2 all for being in off position, promptly all there is not electric current to flow through on first coil 100 and second coil 200, at this moment, first common 11 and first normally-closed contact 12 keep attracting state, second common 21 and second normally-closed contact 22 keep attracting state, the 3rd common 31 and the 3rd normally-closed contact 32 keep attracting state, and the 4th common 41 and the 4th normally-closed contact 42 keep attracting state.This shows that power supply and motor M disconnect, the work loop of motor M is in off-state, so motor M can not be worked.
As shown in Figure 2, be the working circuit diagram during first signal input part H1 input direct current signal among Fig. 1.When first signal input part H1 input direct current signal and secondary signal input H2 did not have input signal, the first direct current relay K1 was in running order, and the second direct current relay K2 is in off position, and promptly having only on first coil 100 has electric current to flow through.So first common 11 and first normally-closed contact 12 disconnect first common 11 and 13 adhesives of first normally opened contact; Second common 21 and second normally-closed contact 22 disconnect second common 21 and 23 adhesives of second normally opened contact.Because the second direct current relay K2 is in off position, the 3rd common 31 and the 3rd normally-closed contact 32 still keep attracting state, and the 4th common 41 and the 4th normally-closed contact 42 still keep attracting state.This shows that positive source is connected with the motor M positive pole, power cathode is connected with the motor M negative pole, so the work loop of motor M is connected, motor M is started working, and motor M is rotated in the forward.That is, motor M is rotated in the forward and drives the lamp holder be connected motor M and be rotated in the forward and realize that light angle is comprehensive adjustable.
As shown in Figure 3, be the working circuit diagram during secondary signal input H2 input direct current signal among Fig. 1.When secondary signal input H2 input direct current signal and the first signal input part H1 did not have input signal, the second direct current relay K2 was in running order, and the first direct current relay K1 is in off position, and promptly having only on second coil 200 has electric current to flow through.So the 3rd common 31 and the 3rd normally-closed contact 32 disconnect the 3rd common 31 and 33 adhesives of the 3rd normally opened contact; The 4th common 41 and the 4th normally-closed contact 42 disconnect the 4th common 41 and 43 adhesives of the 4th normally opened contact.Because the first direct current relay K1 is in off position, first common 11 and first normally-closed contact 12 still keep attracting state, and second common 21 and second normally-closed contact 22 still keep attracting state.As seen from Figure 3, positive source is connected with the motor M negative pole, and power cathode is connected with the motor M positive pole, so the work loop of motor M is connected, motor M is started working, and the motor M reverse rotation.That is, the motor M reverse rotation drives the lamp holder reverse rotation that is connected motor M and realizes that light angle is comprehensive adjustable.
As shown in Figure 4, be working circuit diagram when the first signal input part H1 and secondary signal input H2 all import direct current signal among Fig. 1.When the first signal input part H1 and secondary signal input H2 all import direct current signal, all in running order at the first direct current relay K1 and the second direct current relay K2, promptly all there is electric current to flow through on first coil 100 and second coil 200.At this moment, first common 11 and first normally-closed contact 12 disconnect first common 11 and 13 adhesives of first normally opened contact; Second common 21 and second normally-closed contact 22 disconnect second common 21 and 23 adhesives of second normally opened contact; The 3rd common 31 and the 3rd normally-closed contact 32 disconnect the 3rd common 31 and 33 adhesives of the 3rd normally opened contact; The 4th common 41 and the 4th normally-closed contact 42 disconnect the 4th common 41 and 43 adhesives of the 4th normally opened contact.This shows that power supply and motor M disconnect, the work loop of motor M is in off-state, so motor M can not be worked.So, adopt the first direct current relay K1 and second direct current relay K2 series connection control motor M forward, reverse rotation, and at forward, when the reverse rotation signal exists simultaneously, motor M and power supply disconnect, guarantee motor M not because of misoperation burns out, method is simple, dependable performance.
