摘要： When a forward direction voltage of any of several LEDs 14 to 20 is lowered, a drain voltage of an NMOS transistor 70 employed in any of series regulators 24 to 30 becomes higher than a defined voltage. A zener diode ZD1, which is connected to the LED where the abnormal condition occurs, becomes conductive. A voltage, which is increased from the defined voltage, is applied to a negative input terminal of a comparing amplifier 72, and an output voltage of the comparing amplifier 72 is lowered by this increased voltage portion so that a gate voltage of the NMOS transistor 70 is lowered. A current flowing through the NMOS transistor 70 is decreased. Even if an abnormal condition caused by a voltage drop occurs in any of the LEDs 14 to 20, then the LEDs 14 to 20 can be protected.

摘要： An ON/OFF-operation of a main switch SW and auxiliary switches SW1 to SW5 is controlled by a microcomputer 28. Electromagnetic energy in a transformer T is accumulated in an ON operation of the main switch SW and discharged in the transformer T sequentially to output blocks 14 to 22 on the secondary side in an OFF operation of the main switch SW. The electromagnetic energy is discharged twice separately to the output blocks 14, 18 connected to semiconductor light sources A, C having a heavy load, respectively, in one control period T, whereas the electromagnetic energy is discharged only once to the output blocks 16, 20, 22 connected to remaining semiconductor light sources B, D, E, respectively. Therefore, the peak value of the primary current I1 flowing through the primary winding L of the transformer T can be reduced.

摘要： A discharge lamp lighting circuit includes a DC/DC converter which generates from an input voltage a drive voltage to be applied to a discharge lamp of a driven object. A first drive voltage generating path has one end to which the input voltage is applied, and at the other end of which is an output capacitor on an output side of the DC/DC converter. A second drive voltage generating path has one end to which the input voltage is applied, and at the other end of which is the output capacitor. The second drive voltage generating path is different from the first drive voltage generating path. A control circuit controls ON/OFF of the first drive voltage generating path. The discharge lamp lighting circuit is arranged so that the voltage of the output capacitor when the first drive voltage generating path is in an ON-state becomes higher than the voltage of the output capacitor when the first drive voltage generating path is not so.
