Light-source lamp unit, light-source device and projection-type display apparatus
First Claim
1. A light-source apparatus comprising:
- a light-source lamp unit including a light-source lamp and a lamp information storing device that stores lamp information about the light-source lamp;
a sensor that senses the lamp information obtained by the lamp-information storing device;
a memory that stores lamp information obtained by the sensor; and
a drive and control device that drives and controls the light-source lamp based on the lamp information sensed by the sensor.

Abstract
A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.
