 1 is a circuit diagram for driving a sensor or the like according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram for driving a sensor or the like according to the present invention.

The present invention is a direct current amplification circuit part composed of four transistors TR2, TR3, TR4, and TR5 having an input of the brightness sensor 101 as shown in FIG.

The transistor TR5 is installed to use the photocouplers P1, P2 and P4 connected to the three-stage switch 300 as a load.

1, the four-stage selection switch 400 and the four photocouplers P1, P2, and P3, which are provided with contacts so that four different resistors are connected to one transistor TR1, Stage switch 500 is connected to the neutral three-stage switch 500 and the other transistor TR6 so that the necessary operation is performed according to the position of the three-stage switch 500. [

In addition, C in Fig. 1 is a general infrared sensor circuit portion including a triac.

Subsequently, FIG. 1D shows an electronic transformer and an LED lamp in which a starting current is generated even at a very weak current.

The present invention is provided with a DC amplification circuit part A composed of four transistors whose input is the light intensity sensor 101, and the transistor is installed for use as a load of a photocoupler connected to the three-stage switch 300.

A four-stage selection switch 400 and a photocoupler, to which a plurality of different resistors are connected, are connected to the third-stage switch 300 and the transistor.

Also, an infrared sensor circuit portion C, which is an infrared sensor 500 including the triac, is connected.

In addition, an electronic transformer for generating a starting current of the LED lamp 600 is provided.

At this time, the three-stage switch 300 is provided so as to be divided into a right-hand method illumination-dedicated position for repeating the security lighting and the sensor lighting irrespective of the automatic position on the left, the neutral position where the security illumination is not turned on,

Prior to the operation of the infrared sensor 500, the brightness sensor 101 is given priority so that not only the sensor circuit but also the security illumination function is stopped by the left operation of the three-stage switch 300, The security light is turned on and the stop function of the infrared sensor circuit part C is also released so as to perform the role of a sensor or the like.

In addition, four photocouplers P1, P2, P3, and P4 are driven by a signal input through the DC amplification circuit portion A, which receives the photometric sensor 101 as an input when the three-stage switch 300 is operated, Stage switch 300 to perform the fitting operation of the three-stage switch 300 faithfully by the change of the secondary resistance value.

In addition, the configuration is such that the brightness of the security illumination is adjusted by the four-stage selection switch 400 having a different number of resistors while connecting the triac and the transistor.

The operation of the present invention constructed as described above will be described.

As shown in FIG. 1, in the present invention, a power source supplied to the LED lamp 600 is installed to be supplied to the LED lamp by converting an AC voltage into a DC voltage through an electronic transformer D and converting the DC voltage into DC.

The electronic transformer D is installed such that a triac C connected in series to the electronic transformer D is turned on by a signal generated in the reaction of the infrared sensor 500.

At this time, the voltage input through the input terminal 100 is set so that the voltage supplied by the electronic transformer D is inputted at a maximum value close to 220V so that the final LED lamp 600 lights up brightly.

The operation of the LED lamp is started by the photocoupler on the load side of the DC amplification circuit part A which senses a change in the resistance value of the light intensity sensor 101, The operation is stopped, and the security illumination is turned on / off.

Subsequently, the DC amplification circuit section A applies DC power generated weakly by the R1 resistor to the bridge rectifier circuit of the electronic transformer C, and then, using the AC voltage generated on the secondary side of the final transformer, And is supplied to the circuit section (A) and the infrared sensor circuit section (C), respectively.

At this time, the voltage generated in the coil CO3 is too low to smoothly operate the two circuits, and the voltage is once again raised by the coil CO4 to supply a stable current to the two circuits.

When the position of the three-stage switch 300 is determined by the user in the state of the operation waiting state of 3 mA as described above, whether the security light or the sensor is to be lighted or not is determined by the DC amplification circuit part A and the DC (P1, P2, P3, P4) which are operated by a power supply supplied by the amplifier circuit portion (A).

When the position of the three-stage switch 300 is set to the left side, one side of the switch is in contact with the neutral, and the neutral is negative, so that one terminal of the secondary side of the photo- And the other terminal is already connected to the photocoupler P3, but is also connected to the base of the transistor TR1 through the selection resistor.

In addition, if the secondary resistance of the photocoupler P1 is low, a forward current flows through the base of the transistor TR1, so that the collector and the emitter become conductive.

That is, at the time of operation of the photocoupler P1 by the resistance value selected by the four-stage selection switch 400, both ends of the triac are made conductive, thereby deriving the illuminance of the selected security illumination at all times.

When the ambient light of the brightness sensor 101 is bright, the resistance value of the brightness sensor becomes low (low resistance), and the base voltage of the transistor TR2 rises (increases), so that the collector voltage of the transistor TR2 becomes low, (TR3) and (TR4) and (TR5) are turned OFF.

That is, the primary side current of the photocouplers P1 and P2 connected to the collector of the transistor TR5 connected to the load of the series connection does not operate intermittently, and the secondary side resistance remains unchanged, The photocoupler P4 connected to the emitter load of the transistor TR5 does not operate and the photocoupler P2 must operate so that the reverse bias BIAS voltage is applied to the base of the transistor TR6, All operations are stopped by the resistance value of the light intensity sensor 101. [

Conversely, if the ambient light of the brightness sensor 101 is dark, the resistance value of the brightness sensor 101 rises (high resistance), the base voltage (+ voltage) of the transistor TR2 becomes low, , (TR4), and (TR5) are in the ON state.

Then, the operation of applying the operating voltage to the primary side of the photocouplers (P1), (P2), and (P4) lowers the resistance value of the secondary side.

A reverse bias voltage is applied from a high resistance to a low resistance at the secondary side of the transistor TR6 and the photocoupler P2 so that the infrared sensor circuit portion C enters a standby state. The current flows to the selected resistance value of the switch 400, and the security light is turned on.

In addition, when a car or a person approaches in this state, the LED lamp automatically switches to maximum light intensity from the security light, and after 20 seconds, it returns to the security light again.

Subsequently, when the three-stage switch 300 is set to the right side, the neutral position is away from the left, and the right side is in the state of being in contact with the right side, and the right side becomes the negative potential.

When the negative potential on the right side of the three-stage switch 300 is connected to the terminal on the opposite side of the primary side of the photocoupler P3, positive potential is already connected to? Of the photocoupler P1, The photocoupler P3 is connected in series with the resistor while the photocouplers P1, P2 and P3 are applied with the operating voltage divided into the primary side irrespective of the operation of the transistor TR5 .

That is, the primary side of the photocouplers P1, P2, and P3 is inoperable because the primary side of the photocouplers P1, P2, and P3 can operate and the secondary-side potential of the photocoupler P1 is shifted to the right side. The photocoupler P3 influences the transistor TR1 for security illumination while transmitting a reverse bias voltage to the base of the transistor TR6 so that the security lighting is turned on irrespective of the operation of the DC amplifying circuit portion A .

The LED lamp is automatically switched from the security light to the maximum light intensity when a car or a person comes in contact, and after a certain time elapses, it returns to the security light irrespective of the brightness around the LED lamp.

When the three-stage switch 300 is adjusted to the neutral position, the neutral potential is not in contact with the left or right but is in the middle-potential state, and the photocouplers P1 and P3 are turned on The security light does not light up.

The photocoupler P2 for releasing the bias voltage of the transistor TR6 is affected by the DC amplification circuit part A and the sensor does not operate when the surroundings are bright and the standby state .

It is similar to a nighttime operation switch of a conventional sensor, but in the sensor of the present invention, the operation is performed at a standby current of 3 mA.

When the three-stage switch 300 is placed in the left position, the port-coupler P4 is used for security illumination, and when the brightness sensor 101 is bright, the security light is turned off and the sensor is not operated However, when the crime prevention lighting is turned on when the crime prevention light is turned on, it is judged that the security light itself does not need to turn on the security light because the light value of the brightness sensor is lowered by the light of the light sensor Turn off security lights.

That is, the photocoupler P4 is used to solve the problem that the circulation cycle in which the periphery of the sensor becomes dark again and the security light is turned ON again by the above-described operation, and the security light is repeatedly turned on and off repeatedly .

The direct current amplifying circuit part A operates by the light intensity sensor 101 and the left position of the three-stage switch 300 is (automatic position). When the luminance sensor 101 is placed in the dark, + Voltage goes down. At this time, transistor TR5 is turned on, and the security light is turned on.

The primary operation voltage of the photocoupler P4 connected to the emitter load of the transistor TR5 is generated and the secondary is changed to a low resistance value so that the positive potential of the point 1 instantaneously flows through the R2 resistor and the photocoupler P4, (Bypassed) to the potential through the secondary resistance of the diode.

In addition, the fact that the + potential drops to the negative potential causes the + voltage to become lower and the + potential to become lower than it was originally, as the resistance of the brightness sensor 101 becomes dark and the + voltage at point 1 becomes lower.

That is, when the lightness sensor 101 is dark, the transistor TR5 is turned on and the photocoupler P1 is operated to brighten the security light. However, the + potential of the point 1 is increased by the operation of the photocoupler P4 The light feedback loop cycle is interrupted, and the security light is turned on steadily.
