关于LED灯专业知识：
1.The term"lifetime" is often used to describe end-of-life criteria such as when lumen maintenance falls below a defined threshold.
2. The identifition method selected shall take into account the effect of exposure to light,and heat.
3.Sample source shall be selected to be sufficiently representative of the overall population being tested.
4.care should be taken to minimize any grafts in the immediate vicinity of the devices under test.
5.The power supply have a voltage waveshape such that the total harmonic distortion does not exceed 3% of the fundamental.
6.The current can be de-rated as a function of temperature in accordance with the manufacture's recommendation.
7.It is strongly recommended that photometic and colormetric values be determined from total spectral radiant flux measyrements using a spectroradiometer.
8.Catastrophic LED light source failure shall be reported and included in the test report.

1 灯的寿命往往是用来形容报废标准的，例如灯的照度何时开始低于标准值
2 所选择的鉴定方法应考虑到光和热的影响，
3.样本来源应选择具有足够的代表性且总的测试数量应达到一定标准。
4.要加强足够的重视尽量降低测试过程中任何紧挨的拼接部分
5 电源电压波形保证了总谐波失真不超过基本部分的3 ％。
6 目前按照生产的协定可随其温度的变化予以设定。
7 强烈建议利用光谱来测定总光谱辐射通量并衡量其成像和视觉成色水平
8.可怕的光源的测试失败应该在测试报告中被提及和总结。
9 色度转变应当通过监控每个成像和色度测试的间隔 来衡量并报告它的测试时间。

1 .“终生”这个术语常常用来形容报废标准，如，何时流明维持值低于规定的限值。
2. 鉴定方法的选择应考虑到暴露于光源和热源的影响.
3. 样品来源应在参与测试的总人口中选择具有充分代表性的。
4. 应当采取措施尽量减少在测试中的设施的任何邻近联合影响。
5. 电源电压波形总谐波失真基本不超过3 ％。
6. 电流可以根据生产者的建议随温度函数而递减。
7. 强烈建议光度和比色数值要根据分光辐射度计测得的总光谱辐射通量确定。
8. 灾难性的LED光源故障应当报告并包括检测报告。
9. 在每一个光度检测间隔里，测量色度流明维持测验时间过程中的色度转变都必须测量和报告.
