Compared with the prior art, the invention has the following beneficial effects:

in the daytime, because the light control function is used, the lamp in the internal relay of the light control component is completely turned off at the turn-off position, the light control component is switched to work at night, the internal relay of the light control component is at the turn-on position, the micro-lighting drive 1 is powered on to work, the LED-1 is lightened, and the radar control component is powered on to work at the same time, so that the internal relay is in the standby state at the turn-off position, the timing control component is powered on to start timing and output a high-level signal to enable the internal relay to be in the turn-on position, when the radar control component detects that a moving object in a specified range sends out a high-level signal to enable the internal relay to be turned on to control the drive 2 to work, the LED-3 is lightened, at the moment, the radar control component outputs a low-level internal relay to turn off the LED-2 and the LED-3 are in the turn-off state when the detected object leaves the detection range or is static, when the timing control assembly times to 6 hours (namely, the next midnight), the timing control assembly outputs a low level signal and an internal relay is turned off to enable a drive C power-off LED-3 to be extinguished without being controlled by a radar, only when the internal relay of the light control assembly is turned off in the daytime and the timing control assembly stops timing when the timing control assembly stops timing, the light control assembly waits for the light control assembly to work again to obtain timing at night, but 3 independent control devices and 3 LEDs to drive and load are needed, most importantly, the mounting position of the light control assembly a is that the light sensor must avoid the light of a lamp and can receive natural light, if the light sensor is irradiated by the light of the lamp, the light sensor is repeatedly turned over at a critical point, the timing control assembly stops timing when the relay of the light control assembly is turned off when the light control assembly stops timing action of 6 hours, therefore, the light control assembly a is mounted at a proper position, the invention adopts the design of integrating light control, radar control and timing control, saves cost, reduces space and enhances stability, comprises a main circuit, the main circuit is an AC input module, an EMI module, a voltage reduction rectification module and a filter module which are sequentially and electrically connected and outputs 24V working voltage, meanwhile, 24V voltage is supplied to action coils of relays T1 and T2, power is supplied to a radar control module through a voltage regulator tube D1 of R3 to enable the radar control module to work, power is supplied to a comparator U1 through a voltage regulator tube D5 of a resistor R16 to enable U1 to work, a pin 6 of the U1 established by voltage division of the resistor R6 and the resistor R7 serves as a reference voltage, a pin 5 of the U1 serves as control signal input voltage, when the resistance value of the photosensitive RT is very small in the daytime when the photosensitive RT receives strong illumination, the low potential of the 5 pin of the U1 enables the low potential radar control module at the chip trigger forbidden end of the Z in the radar control module to be blocked, and the relays T1 and T2 do not work when the radar outputs low potential and the triode Q1 is cut off; the triode Q2 is cut off because the low potential of the pin 5 of the U1 is lower than the low level output by the pin 7 of the reference potential comparator U1 with pin 6, and the U2 of the Q5 cut-off timing control module does not work due to no working voltage and can not time due to the cut-off of the Q2, and the relay T2 does not work; because the photo-couple G of the cut-off micro-brightness control module of the Q2 is not conducted and the drive C does not work, at the moment, the whole system is controlled to be in an off state, when the system is in weak illumination at night, the potential of a 5 pin of a photosensitive RT resistance value increase U1 is increased and is larger than the forbidden voltage (generally 1.22V) of a chip trigger forbidden end of Z in the radar control module, the radar control module works, if a moving object exists in a radar detection range, a high level is output, a D2 and R4 enable a triode Q1 to conduct a relay T1 to be closed to drive a B electric working point to light a load LED, if no moving object exists in the radar detection range, a low level Q1 is output to be in a standby state, and because the potential of the 5 pin of a U1 is increased and is larger than the potential of a reference voltage pin 6, at the 7 pin of the U1 at the moment, the high level signal is supplied to a base electrode of the triode Q2 through R10 to conduct the transistor Q2 to conduct the conduction, the conduction of the triode Q2 is enabled, and the photo-couple G of the drive C to conduct the normally closed working point to light of the load LED 84 through the normally-off micro-relay T42 Slightly bright, because the base of the transistor Q5 of the Q2 is conducted from R14 to Q2 low level to start the U2 powered operation timing, the 3 pin of U2 outputs high level to turn on the transistor Q3 through R18, the base of Q4 is conducted through R19 and Q3 low level to make the relay T2 and the action coil of the relay T1 work in parallel and receive the control of radar signal, when the 3 pin of U2 outputs low level to make Q3 and Q4 cut off the action coil of the relay T2 when reaching the timing, at this time, the relay T2 is in the normally closed state to cut off the half/full bright control resistance RS of the driving B to make the driving B in the half bright operation state, the state is kept until the RT low level U1 outputs low level in daytime to cut off Q5 to make the U2 power-off and stop the work waiting for repeating cycle again late, further, as shown in figure 2, the photo resistance controls the potential of the positive input terminal 5 pin of the comparator UI, the point uses a resistor R to adjust the potential of the point, and two conditions are met, wherein firstly, according to the potential requirement (generally 1.22V) of a radar control chip trigger prohibition end, the 5 th pin in the daytime is less than 1.2V, the evening critical time is more than 1.3V, the potential simultaneously requires the 5 th pin in the daytime is less than a reference potential pin 6 of a comparator, the evening critical time is more than the reference potential pin 6, so that the control system is closed in the daytime and opened in the evening critical time, the opening state in the critical time is seen again, when the critical opening is just started, the voltage fluctuation is likely to return to the closing state, therefore, positive feedback is arranged in a circuit, a positive signal is fed back to the 5 th pin by the 7 th pin of U1 after critical utilization through RO and a diode D6 to avoid the phenomenon of overturning, and the 7 th pin outputs a high level after the U1 critical, so that the Q2 conducts a thyristor Q6 to drive a C working point to brighten, the micro-brightness is absorbed by the adjacent photosensitive resistor to turn the U1 to extinguish the load and to be slightly bright, negative feedback is arranged in the circuit, when the 7-pin output high-level Q2 of the U1 is conducted after critical, the reference potential pin 6 forms negative feedback through the D10, R22 and Q2 to the ground to reduce the 6-pin reference potential of the U1 so as to overcome the interference caused by the micro-brightness, the Q2 is conducted due to the high-level output by the 7-pin after the U1 is critical, the U1 is conducted due to the conduction of the base of the triode Q5 of the conduction timing control module of the Q2 from the R14 to the Q2 low-level to enable the U2 to obtain the electric work timing to start, at the moment, when a moving object exists in the radar detection range, the high-level output is enabled to enable the triode Q1 to conduct the T1 through the D2 and the R4 so as to close the B to drive the electric work LED, the load LED is greatly high-brightness and the high brightness is enough to enable the photosensitive resistor to absorb the photosensitive resistor to enable the U1 output low-level Q2 to stop the electric timing when the radar is in the radar detection range, and the radar output signal is kept to be supplied to the positive signal of the D828653, so that the radar in the radar state The state is used for timing and is not turned off, when the radar high output state is changed into a low output state after time delay, positive signals taken by D9 and a resistor R20 are quickly lost, a load LED is extinguished, a small time difference exists between the quick loss of the signals and the extinction of the load LED, and the timing has a power-off time, so an integral circuit is arranged between the radar output and a base electrode of Q2, the integral circuit consists of D9, C7 and R20 and is used for overcoming the existing time difference, parameters of D9, R20 and C7 are determined according to an integral formula U0 ^ 1/RC ^ idctt, the condition that RC (t) > tk is satisfied, a drive B slightly changes on the basis of the original design, the constant current control resistor is increased to make the constant current power half of the original power, lead wires at two ends of the constant current control resistor are respectively connected with S1 and S2 of figure 2, even if the resistor RS is connected in parallel, the resistance value of the resistor RS is adjusted to reach the full power, and is used for state control of half power and full power, thereby let this circuit have the actual demand energy-conserving effect that satisfies 300W internal power like the design of places such as street lamp tunnel lamp garden lamp parking area and be showing to can the full-automatic of independent control LED intelligence, need not complicated intelligent control software system and lay more and longer control scheme and

To sum up, the intelligent full-automatic LED lamp control circuit, during use, the lamp is completely extinguished at the turn-off position of the internal relay of the light control assembly due to the action of light control in daytime, the light control assembly is switched to work at night, at the moment, the internal relay of the light control assembly is at the turn-on position, the micro-lighting drive 1 is powered on, the LED-1 is lighted, and at the same time, the radar control assembly is powered on, so that the internal relay is in the standby state at the turn-off position, at the moment, the timing control assembly is powered on for timing and outputs a high level signal to enable the internal relay to be at the turn-on position, when the radar control assembly detects that a moving object in a specified range sends a high level signal to enable the internal relay to be turned on to control drive 2 to be turned on, at the moment, the internal relay of the timing control assembly drives the C to also work at the turn-on LED-3, and when a detected object leaves the detection range or is static, the radar control assembly outputs a low level internal relay to turn-off LED-2 to be turned on And the LED-3 is in a turn-off state, when the timing control component times to 6 hours (namely, the next midnight), the timing control component outputs a low level signal to turn off the internal relay to turn off the LED-3 which drives the C power failure and is not controlled by a radar, only when the timing control component turns off the internal relay of the light control component in the daytime and stops timing, the light control component waits for the work conversion of the light control component to obtain power again for timing at night, but 3 independent control devices and 3 LED drives and loads are needed, most importantly, the installation position of the light control component a, the light sensor must avoid the light of the lamp and can receive natural light, if the light sensor is irradiated by the light of the lamp, the phenomenon of repeated overturning occurs at a critical point, the light irradiation of the light of the lamp also enables the timing control component to stop timing when the internal relay of the light control component is turned off, and the timing effect of 6 hours is lost, therefore, the light control component a needs to be installed at a proper position, the scheme adopts the design of light control, radar control and timing control and integration, saves cost, reduces space and enhances stability, the invention comprises a main circuit, the main circuit is an AC input module 1, an EMI module 2, a voltage reduction rectification module 3 and a filter module 4 which are sequentially and electrically connected to output 24V working voltage, the 24V voltage is supplied to action coils of relays T1 and T2, meanwhile, power is supplied to a radar control module 5 through a R3 voltage stabilizing tube D1 to enable the radar control module 5 to work, power is supplied to a comparator U1 through a resistor R16 voltage stabilizing tube D5 to enable the U1 to work, 6 pins of the U1 established by dividing voltage of the resistors R6 and R7 are used as reference voltage, 5 pins of the U1 are used as control signal input voltage, when the resistance value of photosensitive RT is very small in daytime, 5 pins of the U1 enable a chip at a low potential in the radar control module 5 to trigger to prohibit the radar control module 5 from a low potential end to be blocked, the relay T1 and the relay T2 do not work when the radar outputs a low potential and the transistor Q1 is cut off; because the low potential of the pin 5 of the U1 is lower than the low level output by the pin 7 of the reference potential comparator U1 with pin 6, the triode Q2 is cut off, and because the Q2 is cut off, the U2 of the Q5 cut-off timing control module 7 does not work due to no working voltage and can not time, and the relay T2 does not work; because the optocoupler G of the cut-off micro-bright control module 8 of the Q2 is not conducted and the driven C does not work, at the moment, the whole system is controlled to be in an off state, when weak illumination is seen at night, the resistance value of a photosensitive RT is increased by 5 pins of the U1 and is larger than the forbidden voltage (generally 1.22V) of a chip trigger forbidden end of Z in the radar control module 5, the radar control module 5 works, if a moving object exists in a radar detection range, a high level is output, the triode Q1 is conducted by the D2 and the R4, the relay T1 is conducted to be closed to drive the B gain electric working point to light the load LED, if no moving object exists in the radar detection range, a low level Q1 is output to be in a standby state, and because the 5 pin potential of the U1 is increased and is larger than the 7 pin of the U1 at the moment, the high level is supplied to the base electrode of the triode Q2 by the R10 to be conducted, the triode Q2 to be conducted, and the C is driven to be conducted by the normally closed working point T3884 to light relay T73742 to be conducted by the micro-on micro-bright point of the Q468, and the radar control module 8 is conducted by the micro-bright point to be conducted by the micro-bright point When the load LED is slightly lighted, the base of a triode Q5 of a Q2 turn on from R14 to Q2 low level to start the U2 power-on operation timing, the 3 pin output high level of U2 turns on a triode Q3 through R18, the base of Q4 turns on through R19 and Q3 low level to enable a relay T2 and an action coil of the relay T1 to work in parallel and receive the control of radar signals, when the 3 pin output low level of U2 reaches the timing time, Q3 and Q4 are cut off and break the action coil of the relay T2, at this time, the relay T2 is in a normally closed state to break a half/full bright control resistor RS of a drive B, the drive B is in a half bright operation state, the state is maintained until RT low resistance U1 output low level in daytime and Q5 is cut off to stop the U2 power-off operation waiting for repeated cycles later, and further, as shown in figure 2, the positive input potential of a photosensitive resistor UI 5 controls the comparator UI, the point uses a resistor R to adjust the potential of the point, and two conditions are met, wherein firstly, according to the potential requirement (generally 1.22V) of a radar control chip trigger prohibition end, the 5 th pin in the daytime is less than 1.2V, the evening critical time is more than 1.3V, the potential simultaneously requires the 5 th pin in the daytime is less than a reference potential pin 6 of a comparator, the evening critical time is more than the reference potential pin 6, so that the control system is closed in the daytime and opened in the evening critical time, the opening state in the critical time is seen again, when the critical opening is just started, the voltage fluctuation is likely to return to the closing state, therefore, positive feedback is arranged in a circuit, a positive signal is fed back to the 5 th pin by the 7 th pin of U1 after critical utilization through RO and a diode D6 to avoid the phenomenon of overturning, and the 7 th pin outputs a high level after the U1 critical, so that the Q2 conducts a thyristor Q6 to drive the C working point to brighten, the micro-brightness is absorbed by the adjacent photosensitive resistor to turn off the U1 to extinguish the load and slightly brighten, so negative feedback is arranged in the circuit, when the 7-pin output high-level Q2 of the U1 is conducted after critical, the reference potential pin 6 forms negative feedback through the D10, R22 and Q2 to the ground to reduce the 6-pin reference potential of the U1 so as to overcome the interference caused by the micro-brightness, the Q2 is conducted due to the 7-pin output high-level after the U1 is critical, the U2 obtains electric working timing by conducting the base of the triode Q5 of the Q2 through the R14 to the Q2 low-level, and the load LED is started by outputting high-level through the D2 and the R4 to conduct the triode Q1 to close the relay T1 to drive the B obtaining electric working point to light the load LED, the power of the load LED is larger than the micro-brightness, so that the high-brightness is enough to enable the photosensitive resistor to absorb the U1 output low-level Q2 to cut off to stop the U6862 electric timing, so that the radar output signal is quickly supplied to the load LED through the D828653 and the base of the radar in the radar detection range, and the high-level R8653 to enable the radar to keep the positive signal to be supplied to be quickly The on state is used for timing and not being turned off, when the radar high output state is changed into the low output state after time delay, positive signals obtained by D9 and a resistor R20 are quickly lost, a load LED is turned off, and a small time difference exists between the quick loss of the signals and the turning-off of the load LED, so that a power-off time is caused during timing, an integral circuit is arranged between the radar output and a base electrode of Q2 and consists of D9, C7 and R20 to overcome the
