摘要： A lighting controller has current driving means which include a shunt resistor connected in series to each of multiple LEDs to detect an LED driving current, a PMOS transistor connected to the positive electrode side of each of the LEDs, and an amplifier for sending an output according to the result of comparison between the respectively detected driving current values and a reference value, and which subject each of the PMOS transistors to ON/OFF operation. Control means includes a Zener diode ZD1 and a Zener diode ZD2 for detecting an abnormality occurring in the current driving means and for sending the abnormality detection result. The control means controls the PMOS transistor to be turned OFF after elapse of a predetermined time upon receipt of the abnormality detection result.

摘要： A lighting control device for a vehicle lighting device is arranged so that loads applied to switching regulators are about equal when driving multiple semiconductor light sources (e.g., LEDs) as multifunctional lamps through the switching regulators. The LEDs are divided into two groups. The LEDs belonging to the first group are driven to be turned ON through a first switching regulator and the LEDs belonging to the second group are driven to be turned ON through a second switching regulator. Maximum values of power to be supplied to the LEDs are set to be about equal to each other, and loads to be applied to the switching regulators are about equal to each other.
