Abstract

In a lamp lighting control circuit according to claim 1 for lighting a lamp (5) with an AC voltage output from an electric generator (2) which rotates in conjunction with an engine, a switching device (SCR2) is connected between the electric generator (2) and the lamp (5) and the switching device (SCR2) is turned on after a delay (Td) from a point of time (T1) when either one of positive and negative half-waves of said AC voltage begins to be generated from said electric generator (2). Preferably, the control circuit may further comprise a lamp effective voltage monitoring circuit (7a) for monitoring an effective voltage of the lamp (5), wherein said lamp effective voltage monitoring circuit (7a) prevents the turning on of the thyristor when it detects an overvoltage of said lamp (5).
