These connection relationships will be described in more detail with reference to FIG. The positive terminal of the first transistor Q1 is connected to the trigger input terminal (terminal 2) of the control IC 150 (this terminal is simultaneously connected to the IC power supply voltage Vcc ), The control IC 150 starts to operate (triggers) by turning on / off the first transistor Q1. In addition, the negative terminal of the first transistor Q1 is connected to the positive potential terminal of the third transistor Q3, and the control terminal of the third transistor Q3 is connected to the high / low The negative terminal of the third transistor Q3 is grounded). When the CDS sensor 110 is operated, the "C" terminal of the connector junction portion is connected to the power supply voltage Vcc The control IC 150 is triggered by the first transistor Q1 and the first transistor Q1 is turned on when the third transistor Q3 is turned on The trigger of the control IC 150 assumes that the third transistor Q3 is turned on. The control terminal of the first transistor Q1 is connected to the motion sensing sensor 140 through a coupling resistor R7 so that the control IC 150 is connected to the CDS sensor 110 Is triggered when the motion detection sensor 140 is activated to "high" on the premise of the motion of the motion detection sensor 140. 4, when the CDS sensor 110 that selectively connects / disconnects the "C" terminal of the connector junction portion operates, a signal (voltage of the connection point P1) from "C " When the first transistor Q1 is turned on and activates the second trigger terminal to 'low' when the signal from the motion detection sensor 140 is activated to 'high' while being activated to 'low' The control IC 150 is triggered and can be set to output the 'high' signal as the operation control signal to the output terminal # 3.
On the other hand, the "C" terminal of the connector junction portion to be turned on / off by the CDS sensor 110 is connected to the control terminal of the fourth transistor Q4 and grounded via the eighth resistor R8 The connection point P1 of the control terminal of the third transistor Q3, the control terminal of the fourth transistor Q4 and the phase potential terminal of the eighth resistor R8 is connected to the terminal "C" And is turned on / off at Vcc.

[ For example, when the signal voltage of the terminal "C" from the CDS sensor 110 is high (when the ambient light is bright), the fourth transistor Q4 is turned off and the fifth transistor The third transistor Q3 is turned off and the third transistor Q3 is turned off and the third transistor Q3 is turned off. 1 < / RTI > transistor Q1 may be disabled (in this case, the control IC 150 is deactivated regardless of the state of the motion sensor), and vice versa, the infrared LED 120 is turned on (When the first transistor Q1 is in an operable state), the control IC 150 is activated by the motion sensing sensor 140 to deactivate the first transistor Q1, Or may be triggered). Of course, on / off of each transistor may be designed in reverse to the above.

Accordingly, the white LED 130 may be turned on or off by turning on / off the second transistor Q2 and the sixth transistor Q6. For example, the output signal from the control IC 150 The second transistor Q2 is turned on and the sixth transistor Q6 is turned on so that the A terminal of the connector junction is shorted from Vcc The white LED 130 may be turned off, and in the opposite case, the white LED 130 may be turned on. Of course, on / off of each transistor may be designed in reverse to the above.
In addition, the control IC 150 assumes the operation of the CDS sensor 110 ('low' activation in the case of FIG. 4) (at this time, the infrared LED 120 is turned off) ) And triggered by the trigger signal of the 'low' input when the motion sensing sensor 140 is to be activated (the 'high' signal in FIG. 4), the output signal is output as high, The sixth transistor Q6 is turned on and the white LED 130 is turned on. Table 1 shows the relationship of these operations.

When the ambient light is dark at night, the first transistor Q1 is turned on and the white LED 130 is turned on according to the detection signal of the motion detection sensor 140. However, when the surrounding environment is bright during the day, The third transistor Q3 is connected between the CDS sensor 110 and the first transistor Q1 and is turned off to block the operation of the first transistor Q1.

Here, the control terminal (base) of the third transistor Q3 and the fourth transistor Q4 are connected to the CDS sensor 110, and the control IC 150 is connected to the sixth and eighth terminals The first resistor R1 and the sixth resistor R6 are connected to the first resistor R1 and the second resistor R2 is connected to the second and the eighth terminals and one end is connected to the first resistor R1, (C) is connected to control the time constant.
