Abstract

One of the main technical parameters of light emitting devices is their service life. The service life and stability of light radiation during operation determine the operating conditions of light sources. By the example of barrier discharge excilamps based on KrCl* (222 nm) and XeBr* (282 nm) exciplex molecules, an optoelectronic method for stabilizing excilamp UV radiation is proposed. The method consists in autocorrecting the radiation power of the excilamps using a UV radiation sensor and an electronic feedback that regulates the power of the excilamps. During of tests for the service life of KrCl and XeBr excilamps, the dependences of the change in the excilamp radiation power on time in a continuous mode of operation were obtained. A new approach to describing the reliability of excilamp operation is discussed. It is shown that instead of such a parameter of light-emitting devices as a useful service life, it is necessary to use a new quantitative characteristic, which is proposed to be called the guaranteed service life of the stable operation of the excilamp.
