<p>A light source device (100) is provided with a light source lamp unit (1) which is detachably attached to the device (100) and a CPU (101) which constitutes the drive control means of the lamp unit. The CPU (101) detects the information about the electric power and service life of a lamp and whether the lamp is new or old carried by the lamp information carrying section (5) of the unit (1) and, when the lamp is turned on, counts the cumulative operating hour of the lamp. The CPU (101) compares the detected service life with the cumulative operating hour and, when the service life has expired, forcibly turns off the lamp. The CPU (101) also warns the user of the necessity of replacing the lamp by displaying a warning a fixed period of time short of the expiration of the service life. Since the information about the kind and characteristics of the lamp is carried by the lamp information carrying section (5) of the unit (1), the light source device (100) can appropriately discriminate and control the turning on/off and service life of a lamp even when a different kind of light source lamp unit is used.</p> |
