Title: Current variable type constant current circuit
Inventor: SUDO AKIRA
IPC: G05F1/56
Filed: 1984-07-20
Abstract: PURPOSE:To make a load current and to attain ease of change by applying a constant current to a load through a base voltage of a transistor (TR) and varying an input voltage of a voltage variable constant voltage circuit so as to vary the said constant current. CONSTITUTION:An emitter voltage VE1 of a TR2 is constant when a base voltage is constant and changed when the base voltage is changed. For example, a current (i) flowing to a load LED1-1 is expressed as i (VE2-VE1)/R3-1, where VE2 is an emitter voltage of a switching TR1-1 and constant. That is, the current (i) is unchanged due to the change in a power supply voltage +V and a forward resistance change in the LED-1 and it is not required to change a current limit resistor R3-1. Even if the load has a rush current, the rush current is limited and the TR1-1 is not destroyed. In changing the current (i), the voltate VE1 is changed by changing the voltage applied to the base of a TR2 by a potentiometer RV to change easily once the constant current of the LED.
