Abstract: In a process in which a current is supplied from a switching regulator to multi-chip LEDs, the forward voltages of the LEDs are respectively detected in forward detecting circuits. The detected values are sent to a microcomputer. In the microcomputer, detected values when the multi-chip LEDs are initially turned on are stored as initial values. A first abnormality deciding value is set from the initial value. The detected values are sequentially stored as updated values. Second abnormality deciding values having conditions stricter than those of the first abnormality deciding value are sequentially set in accordance with the stored updated value. A read value is compared with the first abnormality deciding value or the read value is compared with the second abnormality deciding value to decide whether or not the abnormality of the LEDs is present. When it is decided that the LEDs are abnormal, an LED is turned on to inform a driver of the presence of the abnormality.

Abstract: There is provided a vehicular lamp that can prevent excess current from flowing between an anode and a cathode at the lighting-up start to prevent a damage and life shortening of a cold cathode fluorescent lamp at low cost. The vehicular lamp includes: a cold cathode fluorescent lamp having a cathode, a gate, and an anode; and a lighting controlling unit operable to pre-discharge electricity from the cathode to the gate prior to lighting of the cold cathode fluorescent lamp, in which the lighting controlling unit applies a voltage between the cathode and the anode after once lowering a voltage between the cathode and the gate and then again applies an extraction voltage between the cathode and the gate in order to begin to discharge electricity from the cathode to the anode. The lighting controlling unit may pre-discharge electricity from the cathode to the gate until the temperature of the cathode is substantially equal to that of lighting-up time.
