Measuring and self-calibration method for xenon lamp light source

Abstract

The invention discloses a measuring and self-calibration method for a xenon lamp light source. The measuring and self-calibration method comprises (1) measuring a new light pipe of a xenon lamp, obtaining a spectrogram, a total irradiation amount and irradiation intensity of a characteristic wavelength section of the new light pipe, and simultaneously calibrating a xenon lamp measuring system; (2) when the xenon lamp light pipe works for a period of time and needs measuring and calibration, adopting a measuring method which is the same as the step (1) to measure the xenon lamp light pipe working for a period of time, obtaining a spectrogram, a total irradiation amount and irradiation intensity at the position of the characteristic wavelength section of the xenon lamp light pipe, comparing the spectrograms and the irradiation intensity at the position of the characteristic wavelength section of the new xenon lamp light pipe and the xenon lamp light pipe working for a period of time, and obtaining attenuation conditions of the xenon lamp light pipe; and (3) analyzing consistency of the spectrograms of the new light pipe and the light pipe working for a period of time so as to determine whether to adjust power of the xenon lamp or replace a new light pipe. According to the method, the aim of self-calibration of the xenon lamp is achieved through a spectrum technology.

Description

technical field [0001] The invention relates to a measurement technology of a xenon lamp light source, in particular to a measurement and self-calibration method of a xenon lamp light source. Background technique [0002] It is well known that the performance of polymer materials will be deteriorated or lost due to the influence of the environment during use or storage, such as light, heat, oxygen, humidity, stress, chemical corrosion, etc. This phenomenon is called the degradation of polymer materials. Ageing. Light is an important factor affecting the aging of polymer materials. At present, a series of photoaging equipment has been developed in the world to study the photoaging behavior of polymer materials. The xenon lamp aging test chamber is one of the most commonly used accelerated test equipment for studying the aging behavior of polymer materials. The xenon lamp aging test chamber uses the xenon arc lamp as an artificial light source to irradiate the polymer mater...

Problems solved by technology

To complete the second step of xenon lamp calibration, you need to entrust an overseas laboratory to complete, not only the entire calibration period is long, but also the calibration cost is very expensive

In addition, at present, foreign calibration laboratories need a set of proprietary equipment for optical calibration of xenon light tubes. This equipment is not produced in my country and needs to be imported.
