3.Test MethodA. 稳定化标准 Stabilization Criteria
能源部在2015年7月的SNOPR中提出，集成LED灯在测量前应按照IES LM-79-08的5.0节规定进行稳定。稳定时的环境条件和操作方向在III.C.1和III.C.2节中规定。DOE还在2015年7月的SNOPR中提出，当在30分钟内至少三次读取输入功率和流明输出的稳定变化[（最大-最小）/最小]，间隔15分钟，小于0.5%时，就达到了LED灯的稳定性。能源部包括这一计算，以增加 IES LM-79-08第5.0节中规定的方法进行澄清。DOE还提出，同一型号的多个产品的稳定化可以按照IES LM-79-08第5.0节的规定来进行。
DOE proposed in the July 2015 SNOPR that integrated LED lamps be stabilized prior to measurement as specified in section 5.0 of IES LM–79– 08. The ambient conditions and operating orientation while stabilizing is as specified in sections III.C.1 and III.C.2. DOE also proposed in the July 2015 SNOPR that stability of the LED lamp is reached when the stabilization variation [(maximum—minimum)/minimum] of at least three readings of the input power and lumen output over a period of 30 minutes, taken 15 minutes apart, is less than 0.5 percent. DOE included this calculation to add
clarification to the method specified in section 5.0 of IES LM–79–08. DOE also proposed that stabilization of multiple products of the same model can be carried out as specified in section 5.0 of IES LM–79–08.

B. 输入功率的衡量标准Input Power Metric
DOE在2015年7月的SNOPR中提议，输入功率（瓦）、输入电压（伏）和输入电流（安）应按照IES LM-79-08的8.0节规定进行测量。对于直流输入的LED灯，测量的电压和电流的乘积就是输入电功率。对于交流输入的LED灯，使用连接在交流电源和LED灯之间的功率计来测量输入功率.
DOE proposed in the July 2015 SNOPR that input power (in watts), input voltage (in volts), and input current (in amps) be measured as specified in section 8.0 of IES LM–79– 08. For DC-input LED lamps, the product of the measured voltage and the current gives the input electrical power.
For AC-input LED lamps, the input power is measured using a power meter connected between the AC power supply and the LED lamp.

C. 流明输出指标 Lumen Output Metric
DOE在2015年7月的SNOPR中提出，测角器不得用于光度测量。
因此，DOE在2015年7月的SNOPR中提出，测量流明输出的方法是IES LM-79-08第9.1和9.2节的规定，并建议所有的LED灯，包括定向的8个LED灯，都采用相同的流明输出测量方法。80 FR at 39646-47. DOE没有收到任何关于测量流明输出的拟议测试方法的意见，因此采用了本最终规则中的描述。
DOE proposed in the July 2015 SNOPR that goniophotometers may not be used for photometric measurements.
As a result, DOE proposed in the July 2015 SNOPR that the method for measuring lumen output be as specified in sections 9.1 and 9.2 of IES LM–79– 08, and proposed the same lumen output measurement method for all LED lamps, including directional 8 LED lamps. 80 FR at 39646–47.
DOE did not receive any comments on the proposed test method for measuring lumen output and therefore adopts it as described in this final rule.
--------------------------------------------------------------------------------
D. 灯具效率的衡量标准 Lamp Efficacy Metric
如第一节所述，该测试程序将支持任何潜在的未来一般服务LED灯的节能标准，其中可能包括功效作为制定标准的一个指标。因此，在2015年7月的SNOPR中，DOE建议LED灯的功效（以每瓦流明为单位）通过测量初始流明输出除以测量灯的输入功率（瓦）来计算。由于测试程序中已经包含了输入功率和流明输出的指标，因此提供LED灯的功效计算并不会增加测试负担。这种方法也增加了清晰度，因为它使用DOE制定的测量参数的命名惯例来指定计算。
As discussed in section I, this test procedure will support any potential future energy conservation standards for general service LED lamps, which may include efficacy as a metric for setting standards. Accordingly, in the July 2015 SNOPR, DOE proposed that the efficacy of an LED lamp (in units of lumens per watt) be calculated by dividing measured initial lamp lumen output in lumens by the measured lamp input power in watts. Providing a calculation for efficacy of an LED lamp does not increase testing burden because the test procedure already includes metrics for input power and lumen output. This approach also increases clarity as it specifies the calculation using the naming conventions for measured parameters established by DOE.
------------------------------------------------------------------------------
E. 测量相关色温Measuring Correlated Color
温度 在2015年7月的SNOPR中，DOE建议按照IES LM-79-08第12.4节的规定计算LED灯的CCT。CCT是通过测量相对光谱分布，计算色度坐标，然后将色度坐标与普朗克辐射器的特定CCT相匹配来确定的。DOE没有提出名义CCT方法，因为名义CCT值并不涉及色度图的所有区域。DOE建议，测量相对光谱分布的设置，即计算LED灯的CCT所需的设置，应按照IES LM-79-08第12.0节的规定。该部分描述了使用球体-光谱仪系统和光谱仪或色度计系统来计算CCT的测试方法。此外，DOE还在2015年7月的SNOPR中提议，要求所有光度测量（包括CCT）必须在积分球中进行，并且不得使用测角仪系统。因此，能源部建议用于CCT测量的仪器应符合IES LM-79-08第12.0节的描述，但不包括IES LM-79-08第12.2和12.5节。
Temperature In the July 2015 SNOPR, DOE proposed that the CCT of an LED lamp be calculated as specified in section 12.4 of IES LM–79–08. The CCT is determined by measuring the relative spectral distribution, calculating the chromaticity coordinates, and then matching the chromaticity coordinates to a particular CCT of the Planckian radiator. DOE did not propose a nominal CCT method because nominal CCT values do not address all regions of the chromaticity diagram. DOE proposed that the setup for measuring the relative spectral distribution, which is required to calculate the CCT of the LED lamp, be as specified in section 12.0 of IES LM–79–08. That section describes the test method to calculate CCT using a sphere-spectroradiometer system and a spectroradiometer or colorimeter system. Furthermore, DOE also proposed in the July 2015 SNOPR to require all photometric measurements (including CCT) be carried out in an integrating sphere, and that goniophotometer systems must not be
used. Therefore, DOE proposed that the instrumentation used for CCT measurements be as described in section 12.0 of IES LM–79–08 with the
exclusion of sections 12.2 and 12.5 of IES LM–79–08.

F. 测量显色指数Measuring Color Rendering Index
在2015年7月的SNOPR中，DOE建议增加一项要求，即按照IES LM-79-08第12.4节的规定确定LED灯的CRI，并要求所有光度测量（包括CRI）在积分球中进行。按照建议，测量相对光谱分布的装置 谱分布（计算LED灯的CRI），将按照IES LM-79-08第12.0节的规定进行，但不包括第12.2节和第12.3节。
不包括IES LM-79-08的第12.2和12.5节，因为不会使用测角仪系统。IES LM-79-08的第12.4节还规定，CRI应按照国际照明委员会（CIE）13.3-1995中定义的方法计算。能源部提议，LED灯的测试程序包括CRI的测量方法，以支持即将到来的一般服务灯节能标准的制定。
In the July 2015 SNOPR, DOE proposed to add a requirement that the CRI of an LED lamp be determined as specified in section 12.4 of IES LM–79–08, and to require all photometric measurements (including CRI) be carried out in an integrating sphere. As proposed, the setup for measuring the relative spectral distribution, which is required to calculate the CRI of the LED lamp, would be as specified in section 12.0 of IES LM–79–08 with the exclusion of sections 12.2 and 12.5 of IES LM–79–08, as goniophotometer systems would not be used. Section 12.4 of IES LM–79–08 also specifies that CRI be calculated according to the method defined in the International Commission on Illumination (CIE) 13.3–1995.9 There are currently no industry standards that define or provide instructions for color quality metrics other than the CRI of LED lamps. DOE proposed that the test procedure for LED lamps include measurement methods for CRI in order to support the upcoming general service lamps energy conservation standard rulemaking.
