Abstract
본 발명은 차량의 야간 조명밝기 제어회로에 관한 것으로 특히, 엘이디 구동전압을 발진회로의 영향을 받지 않고 가변저항의 저항치 변화에 연동해서 가변되는 전압으로 공급할 수 있도록 하여 엘이디 구동시 떨림현상을 방지하고, 또 가변저항만을 조절하면 계기등과 엘이디의 밝기가 동시에 조절되도록 하고, 파워 접지단과 시그날 단자는 접지단 분리형 소자를 통해 공통 접지되도록 하여 파워 접지단과 시그날 접지단 사이의 간섭을 방지하므로써 각각의 동작에는 아무런 영향이 없이 시스템이 안정된 상태로 동작할 수 있으며, 벌브 타잎 계기등의 밝기와 엘이디를 분산시켜 구동할 수 있으므로 상기 계기등 구동용 트랜지스터(Q1)가 과부하로 인해 파손되는 것을 방지할 수 있고, 또 콘넥터 결선을 줄일 수 있음은 물론 회로기판의 설계가 용이하여 제품의 생산원가를 절감시킬 수 있는 것이다.The present invention relates to a night light brightness control circuit of a vehicle, and in particular, it is possible to supply the LED driving voltage to the variable voltage in conjunction with the change in the resistance value of the variable resistor without being affected by the oscillation circuit to prevent the shaking phenomenon when driving the LED In addition, by controlling only the variable resistor, the brightness of the instrument lamp and the LED can be controlled at the same time, and the power ground terminal and the signal terminal are common grounded through the separate ground terminal element to prevent interference between the power ground terminal and the signal ground terminal. The system can be operated in a stable state without any influence, and can be driven by dispersing the brightness and the LED of the bulb type instrument light to prevent the instrument transistor (Q1) from being damaged due to overload In addition, the connection of the connector can be reduced, and the design of the circuit board is easy. The production cost of the product can be reduced.
