A Reliability Model of Electronic Ballasts using SR-332

SR-332에 의한 전자식 안정기의 신뢰성 모형

As the level of technology and the standard of living improve, product reliability plays an increasingly significant role. This study has been performed to build a reliability model of electronic ballasts for the low wattage fluorescent lamp. Telcordia SR-332, one of the most widely used reliability specifications, was selected for the model development. We briefly reviewed the basic concepts of the electronic ballast. We then developed a reliability model for the ballast using SR-332 concepts and the reliability has been examined. We further discussed the significance of the first-year failure effect on the mean life.
