The operation principle of the electronic equipment that present pre-ferred embodiments communicates based on direct current supply specifically describes as follows:
In the present embodiment, 220V civil power is converted to the DC power supply of 12V by power transfer module 1, because the positive pole 11 of described DC power supply is directly connected with the ac input end a of described full-bridge rectification bridge 511, and the ac input end b of described full-bridge rectification bridge 511 is also through on-off switch 2 ground connection, therefore, when on-off switch 2 conducting, the ac input end b ground connection of described full-bridge rectification bridge 511, then DC power supply exports driver module 5 to, when on-off switch 2 turns off, the ac input end b of described full-bridge rectification bridge 511 is unsettled, then export driver module 5 to without DC power supply, it should be noted that, the ac input end a of described full-bridge rectification bridge 511, in b, any one end all can be connected with the positive pole 11 of described DC power supply, and the electric power polarity exporting LED drive unit 52 to is constant, therefore, full-bridge rectification bridge 511 can play the effect of fixed polarity, no matter the input of LED lamp B is connected with power supply A is positive and negative, the normal work of LED can be ensured, convenient, in the present embodiment, for convenience of explanation, to be connected with the positive pole 11 of described DC power supply for the ac input end a of described full-bridge rectification bridge 511 and to be described, other situations are not construed as limiting.
First microprocessor 31 receives the remote control command that external remote control equipment sends, this remote control command is the regulating command sent by remote controller, knob, switch etc., first microprocessor 31 according to this remote control command can know user need to LED carry out as regulated the adjustment such as LED luminance or switch operation, first microprocessor 31 exports according to the adjustment operation known conducting and the cut-off that low and high level to the grid G of described field effect transistor 21 controls described field effect transistor 21; When first microprocessor 31 exports high level to the grid G of described field effect transistor 21, the conducting of described field effect transistor 21, then the ac input end b ground connection of now described full-bridge rectification bridge 511, DC power supply exports driver module 5 to; When first microprocessor 31 output low level is to the grid G of described field effect transistor 21, described field effect transistor 21 is ended, then now the ac input end b of described full-bridge rectification bridge 511 is unsettled, exports driver module 5 to without DC power supply; Then first microprocessor 31 gets final product the break-make of DC power supply in control circuit by exporting low and high level.
When described field effect transistor 21 conducting, then DC power supply exports driver module 5 to, DC power supply through described full-bridge rectification bridge 511 for storage capacitor C charges, power for described LED drive unit 52 simultaneously, now have a meeting conducting in the first diode D1 and the second diode D2, then DC power supply exports high level to the second microprocessor 41 through R1; When described field effect transistor 21 is ended, then export driver module 5 to without DC power supply, namely the DC power supply in circuit disconnects, now the first diode D1 and the second diode D2 all ends, then the second microprocessor 41 obtains a low level, thus, the second microprocessor 41 gets final product the break-make of DC power supply in testing circuit according to the low and high level obtained.
Further, first microprocessor 31 can control the make-and-break time of the conducting of described field effect transistor 21 and deadline also i.e. DC power supply by the cycle controlling to export low and high level, in the present embodiment, first microprocessor 31 can control the shutoff that described on-off switch 2 is t1 with the specific interval time of carrying out within the regular hour and operate, using the control signal that the ON time length between twice shutoff operates is modulated as first microprocessor 31 according to described remote control command, when the ON time of described field effect transistor 21 is greater than set point, then represent and be ready to transmit control signal, then first microprocessor 31 starts the conducting and the cut-off that control described field effect transistor 21, the deadline of described field effect transistor 21 is always t1, owing to exporting driver module 5 to without DC power supply within the t1 time, for ensureing the normal work of LED, be then that LED powers in t1 time domestic demand by storage capacitor C, therefore, it is too low that the value of t1 must ensure that the operating voltage of LED within the t1 time can not be fallen, known through experiment test, t1 is preferably 100us, and now need to choose suitable storage capacitor C, with ensure deadline in described field effect transistor 21 in t1 LED can normally work, as as t1=100uS, then the LED of a 12V/5W only needs the storage capacitor C of about 22uF can maintain its reliable and stable work.
Control after described field effect transistor 21 ends the t1 time, to control the time of described field effect transistor 21 conducting (10*t1+t2) at first microprocessor 31.Wherein, 10*t1 is to ensure that the opening time of on-off switch 2 is not less than 10 times of turn-off time, thus ensure that LED can obtain the less stabilized power supply of a mean value fluctuation, it should be noted that, 10*t1 is a preferred value of testing acquisition by experiment, certainly, do not limit other values yet and can ensure that LED obtains the less stabilized power supply that fluctuates yet.In the ON time (10*t1+t2) of described field effect transistor 21, the value of t2 is then as the control signal that first microprocessor 31 is modulated according to described remote control command, first microprocessor 31 controls the different ON time of described field effect transistor 21 according to different remote control commands, thus modulate corresponding control signal according to the different ON time of described field effect transistor 21, as controlled the ON time (10*t1+t2) of field effect transistor 21, t2 is divided into 16 sections, increase progressively with 100uS, from 0uS to 1500uS, then t2 can represent the binary number of 4 (nibbles), if on-off switch 2 keeps the time of conducting to be 1700uS between twice turn-off time t1, then known t2 is 700uS, then representing the data sent is 7, be converted to binary system to be " 0111 ".Therefore, only need be carried out the control of accurate opening time, turn-off time to described on-off switch 2 by first microprocessor 31, corresponding control signal can be sent when not affecting LED normally works.
After first microprocessor 31 sends corresponding control signal, according to the low and high level cycle obtained, second microprocessor 41 can know that the make-and-break time of DC power supply in circuit is also opening time and the turn-off time of described on-off switch 2, then the second microprocessor 41 can according to the opening time of described on-off switch 2 counter push away restore first microprocessor 31 send control signal, the adjustment operation need carried out LED can be known according to the control signal that the first microprocessor 31 of reduction sends, described control signal to be converted to according to the adjustment need carried out the LED operation known the drive singal that LED drive unit 52 can identify by the second microprocessor 41, and the drive singal of conversion is sent to LED drive unit 52, LED is adjusted accordingly according to this drive singal by LED drive unit 52 again, as light modulation, the operations such as switch.
In other optional execution modes, when powering for multiple LED lamp simultaneously, each LED lamp all can receive the control signal of first microprocessor transmission by its second microprocessor, thus can realize unified management control, very convenient, further, the address information of each LED lamp also can be comprised in the control signal that first microprocessor sends, as increased the ON time of one section of field effect transistor 21 to write the address information of each LED lamp, thus in the control signal that first microprocessor is sent, contain the address information of each LED lamp, then each LED lamp can carry out demodulation analysis to control signal by its second microprocessor, only control adjustment is carried out to the LED lamp meeting address information in control signal, achieve and carry out for specific LED lamp the function that controls, more convenient and practical when controlling multiple LED lamp.
