发光二极管(LED)光源和发光二极管(LED)灯具的主要组件可靠性试验指南

[中文适用范围]： 本技术规范提供了使用 LED 光源和普通照明 LED 灯具的主要部件测试来建立产品可靠性信心的指南。它包括使用主要部件的初始鉴定测试和加速压力测试的方法和标准。任何主要部件的性能都会影响最终产品的性能。验证全寿命声明和流明维持预测的技术不属于本技术规范的范围。如果以下主要部件用作 LED 光源或 LED 灯具的组成部分，则应包含在测试中： LED 封装和互连；光学材料；电子组件；冷却系统，包括主动（例如风扇）和被动（例如热界面材料）；建筑材料。不建议将本技术规范用作LED产品性能标准的规范性参考。 [外文原描述]： IEC TS 62861:2017(E) This Technical Specification provides guidelines for establishing confidence in product reliability using principal component testing for LED light sources and LED luminaires for general lighting. It includes methods and criteria using initial qualification tests and accelerated stress tests of the principal components. The performance of any principal component will influence the performance of the final product. Techniques to validate full lifetime claims and lumen maintenance projection are outside the scope of this Technical Specification. The following principal components are included in the testing if they are used as an integral part for the LED light source or LED luminaire: - LED package and interconnects; - optical materials; - electronic subassemblies; - cooling systems, both active (e.g. fans) and passive (e.g. thermal interface material); - construction materials. This Technical Specification is not recommended for use as a normative reference to the LED product performance standards.
