摘要： LED照明行业 LED光电的可靠性和寿命验证方法一方面借助于光电仪表和环境测试设备进行这方面的测试，另一方面通过灯具工作模型用失效率系数来估算其寿命。 LED相关的可靠性试验规范<o:p></o:p> 1.0 目的 建立实验室可靠性测试的标准与规范，完善产品测试标准，提高产品质量。 2.0 适用范围 本标准适用于模组类、柔性灯带类以及直条灯类成品可靠性测试。              3.0 内容 3.1 测试项目 成品可靠性测试包含但不限于以下项目，在提交测试过程中根据实际情况在测试单中注明需要执行的测试项目。<o:p></o:p> o 基础参数测试：产品的基本参数；<o:p></o:p> o 环境测试：温度循环、冷热冲击、高湿热循环、高温存储、低温存储、高温高湿储存、抗UV测试；<o:p></o:p> o 寿命测试：常规衰减测试、高温高湿寿命测试、低温衰减测试、加速衰减测试、规定焊点温度下衰减测试；<o:p></o:p> o 破坏性测试：通断电测试、过压/欠压测试、IP防护等级测试、输入输出短路测试、导线连接处抗拉力测试、灯带弯折性测试、极性保护测试、耐酸性测试、盐雾试验、静电测试；<o:p></o:p> o 机械测试：振动测试、堆码测试、跌落测试。<o:p></o:p>
