The three-step operation selection switch 50 in the light selection unit 2 slides and operates. That is, when the operation selection switch 50 is selected by pushing it toward the circle of the connection between 1 and 2, the front white LEDs D4 and D7 of the light body are selected in a white lit state and illuminate the surroundings.

상기 작동선택 스위치(50)는 2 - 3 간연결의 가운데로 밀어서 선택할 때 전원 오프상태이며 충전배터리(30)의 충전외에 동작하지 않는다. 그리고, 작동선택 스위치(50)는 3 - 4 간연결의 오른쪽으로 밀어서 선택할 때 전면 레드엘이디(D5, D6)가 레드점등 대기상태로 선택되고 있다.The operation selection switch 50 is in a power-off state when selecting by pushing to the middle of the connection between 2-3 and does not operate other than charging the rechargeable battery 30 . And, when the operation selection switch 50 is selected by pushing to the right of the 3 - 4 connection, the front red LEDs (D5, D6) are selected to be in a red lighting standby state.

그러므로, 사용자에 의해 상기 작동선택스위치(50)에 의해 도 3 에 도시된 바와 같이 화이트엘이디 (D4, D7) 또는 레드엘이디(D5, D6)가 선택되면 동시에 전원이 온된다. 이로부터 상기 작동선택스위치(50)에 연결된 신호감지부(1)와 라이트선택부(2)가 구동상태로서 적외선 수신부(20) 및 송출부(25)에 따른 작동하게 된다. Therefore, when the white LEDs (D4, D7) or the red LEDs (D5, D6) are selected by the user by the operation selection switch 50 as shown in FIG. 3 , the power is turned on at the same time. From this, the signal detection unit 1 and the light selection unit 2 connected to the operation selection switch 50 are operated according to the infrared receiving unit 20 and the transmitting unit 25 as a driving state.

상기 충전부(3)의 충전배터리(60)의 VCC_BAT는 상기 작동선택스위치(50)에 연결된 병렬 다이오드(D2, D3)를 통해 VDD 전원으로 공급되는 한편, 상기 작동선택스위치(50)에서 화이트 또는 적색의 N 채널 MOSFET(Q4, Q5)에 각기 연결되어 P 채널 MOSFET(Q2, Q3)를 통해 연결부(TP5, TP9 ; TP11, TP12 ; TP6, TP10)의 도 3 에 도시된 화이트엘이디 (D4, D7) 또는 레드엘이디(D5, D6)가 설치되게 된다. VCC_BAT of the rechargeable battery 60 of the charging unit 3 is supplied as VDD power through the parallel diodes D2 and D3 connected to the operation selection switch 50 , while white or red in the operation selection switch 50 . White LEDs (D4, D7) shown in FIG. 3 of the connections (TP5, TP9; TP11, TP12; TP6, TP10) respectively connected to the N-channel MOSFETs (Q4, Q5) of the P-channel MOSFETs (Q2, Q3) Alternatively, the red LEDs D5 and D6 are installed.

상기 라이트선택부(2)의 화이트 또는 레드의 P 채널 MOSFET(Q2, Q3)로는 신호감지부(1)의 마이크로컨트롤러(10)로부터 라이트 PWM 신호가 P 채널 MOSFET(Q1)를 경유해서 각기 공급되고 있는 바, 이는 상기 마이크로컨트롤러(10)에서 설정된 펄스폭변조신호를 상기 P 채널 MOSFET(Q1)를 통해 PWR_LED 신호로 상기 P 채널 MOSFET(Q1)의 턴온/턴오프에 의해 도 3 에 도시된 화이트엘이디 (D4, D7) 또는 레드엘이디(D5, D6)를 구동시키도록 회로 구성되어 있다. A write PWM signal from the microcontroller 10 of the signal sensing unit 1 is supplied to the white or red P-channel MOSFETs Q2 and Q3 of the write selector 2 via the P-channel MOSFET Q1, respectively. This is because the pulse width modulation signal set in the microcontroller 10 is converted to a PWR_LED signal through the P-channel MOSFET Q1, and the white LED shown in FIG. (D4, D7) or the circuit is configured to drive the red LED (D5, D6).

한편, 신호감지부(1)의 마이크로컨트롤러(10)에서 임의 패턴 신호를 만들어 적외선 송출선을 통해 트랜지스터(Q6)의 턴온됨에 따라 발광다이오드의 적외선송출부(25)를 연속적으로 구동시키며, 상기 발광다이오드는 그에 따라 적외선(IR) 신호를 라이트몸체의 전면부를 통해 송출한다. 여기서 전원이 온상태이면 적외선송출부 (25)의 적외선신호는 지속적으로 송출되고 있다. On the other hand, as the transistor Q6 is turned on through the infrared transmission line by making an arbitrary pattern signal in the microcontroller 10 of the signal sensing unit 1, the infrared transmission unit 25 of the light emitting diode is continuously driven, and the light emission The diode accordingly transmits an infrared (IR) signal through the front part of the light body. Here, when the power is on, the infrared signal of the infrared transmitting unit 25 is continuously transmitted.

라이트몸체의 전면부에 배치된 적외선수신부(20)는 예컨데 사용자 손등의 장해물에 의해 반사되는 신호가 있을 때에 적외선 신호를 감지하며 적외선 수신선을 통해 마이크로컨트롤러(10)에 전달된다. 이렇게 감지된 신호는 토글링 신호를 받아들여 라이트 PWM 신호를 온/오프시켜 라이트몸체의 화이트엘이디 (D4, D7) 또는 레드엘이디(D5, D6)로 공급되는 전원을 제어할 수 있다.The infrared receiver 20 disposed on the front part of the light body detects an infrared signal when there is a signal reflected by an obstacle such as a user's hand, for example, and is transmitted to the microcontroller 10 through an infrared receiver. This sensed signal can control the power supplied to the white LEDs (D4, D7) or the red LEDs (D5, D6) of the light body by receiving the toggling signal and turning the light PWM signal on/off.

즉, P 채널 MOSFET(Q1)를 통해 PWR_LED 신호로써 상기 P 채널 MOSFET(Q1)의 턴온/턴오프에 의해 라이트선택부(2)의 P 채널 MOSFET(Q2, Q3)는 사용자가 선택한 작동선택스위치(50)의 N 채널 MOSFET(Q4, Q5)가 턴온상태에서 P 채널 MOSFET(Q2, Q3)도 턴온상태임으로, 연결부(TP5, TP9 ; TP11, TP12 ; TP6, TP10)의 화이트엘이디 (D4, D7) 또는 레드엘이디(D5, D6)가 선택 구동시켜 야간에 화이트나 레드로 주변을 밝히주게 된다. That is, the P-channel MOSFET (Q2, Q3) of the light selector 2 is activated by the user-selected operation selection switch ( 50) of the N-channel MOSFETs (Q4, Q5) is turned on, and the P-channel MOSFETs (Q2, Q3) are also turned on. Alternatively, the red LEDs (D5, D6) are selectively driven to illuminate the surroundings with white or red at night.
