Dimmer for vehicle use
A dimmer for vehicle use of the present invention has a circuitry in which an output part of an amplifier in an oscillating circuit is grounded through a diode and a ground resistor in series, an anode of the diode is coupled to the output part, and a junction point between a cathode of the diode and the ground resistor is coupled to a non-inversion input part through a feedback resistor. The dimmer can subject stable brightness prevented from changing in response to ambient temperature in the simple and inexpensive circuitry.
