2. 测试设置Test SetupA. 电源 Power Supply
DOE建议，交流电源的线电压波形和输入电压应分别符合IES LM-84-14第5.2和5.4节的规定。第5.2节规定，在LED灯所需的输入频率下，交流电源必须具有正弦电压波形，以便在LED灯运行时，谐波成分的有效值之和不超过基本频率的3.0%。第5.4节部分要求，应用于LED灯的交流电源的电压（RMS电压）应小于或等于额定RMS电压的2.0％。最后，能源部建议不参考IES LM-84-14的第5.3节，该节提供了线路阻抗指南，因为该程序被IES列为可选的，缺乏具体的线路阻抗限制。80 FR at 39651-52. DOE没有收到任何关于拟议的电源要求的意见，因此采用了本最终规则中的描述。
DOE proposed that line voltage waveshape and input voltage of AC power supplies be as specified in sections 5.2 and 5.4 of IES LM–84–14, respectively. Section 5.2 specifies that an AC power supply must have a sinusoidal voltage waveshape at the input frequency required by the LED lamp such that the RMS summation of the harmonic components does not exceed 3.0 percent of the fundamental frequency while operating the LED lamp. Section 5.4 requires, in part, that the voltage of an AC power supply (RMS voltage) applied to the LED lamp be less than or equal to 2.0 percent of the rated RMS voltage. Lastly, DOE proposed to not reference section 5.3 of IES LM–84–14, which provides line impedance guidelines, because the procedures are listed as optional by IES and lack specific line impedance restrictions. 80 FR at 39651–52. DOE did not receive any comments on the proposed power supply requirements and therefore adopts them as described in this final rule.
-----------------------------------------------------------------------------
B. 测试架的布线 Test Rack Wiring
能源部建议，在LED灯的流明维持测试中，测试架的布线要求符合IES LM-84-14第5.5节的规定。该节规定，测试架的布线应符合国家、州或省和当地的电气法规，并符合任何制造商对LED灯的操作和条件建议。本节还要求，每次在测试架上安装LED灯时，都要对电触点包括灯座触点进行检查。80 FR at 39652. DOE没有收到任何关于拟议的测试架布线要求的意见，因此采用了本最终规则中的描述。
DOE proposed that test rack wiring requirements during lumen maintenance testing of LED lamps be as specified in section 5.5 of IES LM–84– 14. This section specifies that wiring of test racks should be in accordance with national, state or provincial, and local electrical codes, and in accordance with any manufacturer operation and condition recommendations for the LED lamp. This section also requires that an inspection of electric contacts including the lamp socket contacts be performed each time the LED lamps are installed in the test rack. 80 FR at 39652. DOE did not receive any comments on the proposed test rack wiring requirements and therefore adopts them as described in this final rule.
-----------------------------------------------------------------------------
C. 电气设置 Electrical Settings
DOE建议要求在IES LM-84-14第5.1节中规定的额定电压下对LED灯进行流明维持测试。对于有多种工作电压的灯，DOE建议在整个测试过程中，集成的LED灯应在额定电压下运行。对于具有多个额定电压（包括120伏）的集成LED灯，DOE建议该灯在120伏下运行。对于具有多个额定电压的集成LED灯没有额定120伏的情况，DOE建议灯在最高额定输入电压下运行。对于具有多种工作模式的LED灯，DOE建议纳入IES LM-79-08的第7.0节，其中规定可调光的LED灯应在最大输入功率下进行测试。对于在最大输入功率下出现多种模式（如多种CCT和CRI）的情况，DOE建议制造商可以选择其中任何一种模式进行测试。对于认证，DOE建议所有的测量（流明输出、输入功率、功效、CCT、CRI、功率因数、寿命和待机模式功率）都在同一操作模式下进行。同上。DOE没有收到任何关于流明维持测试期间的拟议电气设置的意见，因此采用本最终规则中的描述。
DOE proposed requiring lumen maintenance testing of LED lamps at the rated voltage as specified in section 5.1 of IES LM–84–14. For lamps with multiple operating voltages, DOE proposed that the integrated LED lamp be operated at the rated voltage throughout testing. For an integrated LED lamp with multiple rated voltages including 120 volts, DOE proposed that the lamp be operated at 120 volts. For cases where an integrated LED lamp with multiple rated voltages is not rated for 120 volts, DOE proposed that the lamp be operated at the highest rated input voltage. For LED lamps with multiple modes of operation, DOE proposed incorporating section 7.0 of IES LM–79–08, which specifies that dimmable LED lamps should be tested at maximum input power. For cases where multiple modes (such as multiple CCTs and CRIs) occur at the maximum input power, DOE proposed that the manufacturer can select any of these modes for testing. For certification, DOE proposed that all measurements (lumen output, input power, efficacy, CCT, CRI, power factor, lifetime, and standby mode power) be conducted at the same mode of operation. Id. DOE did not receive any comments on the proposed electrical settings during lumen maintenance testing and therefore adopts them as described in this final rule.
----------------------------------------------------------------------------
D. 操作方向 Operating Orientation
能源部建议纳入IES LM-84-14第4.7节的说明，其中规定灯的操作方向与光度测量时相同。在光度测量期间，灯的操作方向将在以下章节中讨论 III.C.2.c. 同上。能源部没有收到任何关于拟议的操作方向要求的意见，因此采用了本最终规则中的描述。
DOE proposed to incorporate the instructions in section 4.7 of IES LM– 84–14, which specifies that the operating orientation of the lamp be the same as during photometric measurement. Lamp operating orientation during photometric measurement is discussed in section III.C.2.c. Id. DOE did not receive any comments on the proposed operating orientation requirements and therefore adopts them as described in this final rule.
==============================================
3.测试方法 Test Method
能源部建议，LED灯的流明维持率测试程序应符合IES LM-84-14第7.0节和IES TM-28-14第4.2节的规定。IES LM-84-14和IES TM-28-14中概述的测试方法确保了可靠的、可重复的和一致的测试结果，而没有重大的测试负担。80 FR at 39652. 流明维持率测试方法将在III.D.3.a至III.D.3.g部分进一步详细讨论。
DOE proposed that the lumen maintenance test procedure for LED lamps be as specified in section 7.0 of IES LM–84–14 and section 4.2 of IES TM–28–14. The test methods outlined in IES LM–84–14 and IES TM–28–14 ensure reliable, repeatable, and consistent test results without significant test burden. 80 FR at 39652. The lumen maintenance test method is discussed in further detail in sections III.D.3.a through III.D.3.g.
-----------------------------------------------------------------------------
A.初始流明输出测量 Initial Lumen Output Measurements
能源部建议要求进行初始流明输出测量，这与IES LM-84-14的7.6节一致，该节规定在开始维护测试之前需要进行初始流明输出测量。初始流明输出是指LED灯在使用III.C.3.a节所述的稳定程序进行初始通电和稳定后，在其寿命开始时提供的测量光量。在测量寿命测试程序的初始流明输出时，将使用III.C.3.c节所述的方法、测试条件和设置要求。制造商在测试LED灯的寿命时，需要使用与灯效计算中相同的初始流明输出值，同上。
DOE proposed requiring an initial lumen output measurement consistent with section 7.6 of IES LM–84–14, which states that an initial lumen output measurement is required prior to starting the maintenance test. Initial lumen output is the measured amount of light that an LED lamp provides at the beginning of its life after it is initially energized and stabilized using the stabilization procedures described in section III.C.3.a. The methodology, test conditions, and setup requirements described in section III.C.3.c would be used when measuring initial lumen output for the lifetime test procedure. Manufacturers testing an LED lamp for lifetime would be required to use the same value of initial lumen output as used in the lamp efficacy calculation. Id.
-----------------------------------------------------------------------------
B. 间隔性流明输出测量 Interval Lumen Output Measurements
能源部还建议要求在最初的流明输出测量之后，进行额外的流明输出测量（称为间隔流明输出测量），并继续定期进行。在最初的流明输出测量之后，按照IES LM-84-14第7.6节的要求，继续定期进行流明输出测量。间隔流明输出的测量是在灯管通电并使用III.C.3.a节中的稳定程序稳定后进行。在测量寿命测试的间隔流明输出时，需要采用III.C.3.c节中描述的方法、测试条件和设置要求。程序。同上。能源部没有收到任何关于稳定化、方法、测试条件或测量间隔流明输出的设置的意见，因此采用本最终规则中的描述。在III.D.4.a节中讨论了间隔期流明输出的测量频率。
DOE also proposed requiring that additional lumen output measurements (known as interval lumen output measurements) be made after the initial
lumen output measurement and continue at regular intervals, consistent with the requirements of section 7.6 of IES LM–84–14. Interval lumen output is measured after the lamp is energized and stabilized using the stabilization procedures in section III.C.3.a. 80 FR 39652. The methodology, test conditions, and setup requirements described in section III.C.3.c would be required when measuring interval lumen output for the lifetime test
procedure. Id. DOE did not receive any comments on the stabilization, methodology, test conditions, or setup for measuring interval lumen output and therefore adopts them as described in this final rule. The frequency of interval lumen output measurements is discussed in section III.D.4.a.
-----------------------------------------------------------------------------
C. 测试时间 Test Duration
在2015年7月的SNOPR中，DOE提出初始流明输出是指灯在其寿命开始时，在最初通电并使用稳定程序稳定后提供的测量光量。80 FR at 39649. 在流明维持测试中，LED灯必须运行一段较长的时间，被称为 "已过的工作时间"。从最初的流明输出测量开始，到最后的间隔流明输出测量记录为止的全部工作时间被称为 "测试时间 "或时间 "t"。测试时间不包括灯管没有通电的任何时间。如果灯管被关闭（可能是为了运送到另一个测试区域或在停电期间），DOE建议关闭状态下的时间不包括在测试时间内。DOE没有规定最低的测试时间要求，因此制造商可以根据LED灯的预期寿命来定制测试时间。然而，DOE承认测试时间对流明维持预测的可靠性有很大的影响，因此提出了最大的失效时间要求，随着测试时间的增加而增加。80 FR at 39649-39650. 这些流明维持率的计算要求将在III.D.4节进一步讨论。能源部没有收到任何关于拟议的测试时间标准的意见，因此采用了本最终规则中的描述。
In the July 2015 SNOPR, DOE proposed that initial lumen output is the measured amount of light that a lamp provides at the beginning of its life, after it is initially energized and stabilized using the stabilization procedures. 80 FR at 39649. During lumen maintenance testing, the LED lamps must operate for an extendedperiod of time, referred to as the ‘‘elapsed operating time.’’ The entirety of elapsed operating time starting immediately after the initial lumen output measurement and ending with the recording of the final interval lumen output measurement is then referred to as the ‘‘test duration’’ or time ‘‘t.’’ The test duration does not include any time when the lamp is not energized. If lamps are turned off (possibly for transport to another testing area or during a power outage), DOE proposed that the time spent in the off state not be included in the test duration. DOE did not specify minimum test duration requirements so manufacturers can customize the test duration based on the expected lifetime of the LED lamp. However, DOE acknowledged that the test duration has a significant impact on the reliability of the lumen maintenance prediction and thus proposed maximum time to failure claims that increase as the test duration increases. 80 FR at 39649–39650. These lumen maintenance calculation requirements are discussed further in section III.D.4. DOE did not receive any comments on the proposed test duration criteria and therefore adopts them as described in this final rule.
