At first, I collect and analyze the relative dates, and statistics fault models. Then I finish the analysis from three aspects, instruction of circuit, stress of surrounding, and tolerance, thus providing basis of design. The following designs are in progress from four aspects, which are circuit design, thermal design, derating using and screening. At last, I make the update generator in batch process, and collect and analyze reliability dates again. I proved that the life of the improved HF electrodless light is over to 60,000 hours.

首先进行了与可靠性相关的数据收集与分析，对故障模式进行统计；然后从电路结构、环境应力及容差三个方面进行可靠性分析，从而为关键的可靠性设计提供了依据；接下来的可靠性设计，从电路设计、热设计、降额使用、筛选四个方面逐一解决了可靠性分析阶段发现的问题；最后，我将改良的发生器批量生产，并从中重新收集了可靠性数据进行计算，事实证明改良后高频无极灯的平均寿命已达到6万小时。
