ABSTRACT:
An apparatus for estimating and displaying the remainder of the lifetime of xenon lamps has a memory in which is stored data on the values of the discharge power of an average xenon lamp for maintaining the irradiance of the light emitted from the xenon lamp on the surface of a sample at a predetermined level, and the corresponding time of use of the average xenon lamp; a discharge power measuring device for measuring the level of the discharge power of a xenon lamp being used to irradiate the surface of a sample while the xenon lamp is being controlled to maintain the irradiance of the light emitted from the xenon lamp on the surface of the sample at a predetermined level; a timer for providing at each of a plurality of predetermined times instructions for starting a comparison of the value of the discharge power of said xenon lamp being used with the stored values; an arithmetic unit for obtaining from the memory the value of the stored cumulative time of use corresponding to the measured value of the discharge power of said xenon lamp being used and the value of the limit time of use of the average xenon lamp, and computing the difference as the estimated remainder of the lifetime of the xenon lamp being used; and a display for indicating the estimated remainder of the lifetime of the xenon lamp.
