Part 2: ErP Energy Efficiency Class Division Standards

2.1 Definition and Importance of Luminous Efficacy Coefficient ƞTM

ErP energy efficiency classes are divided according to the luminous efficacy coefficient ƞTM (Luminous Efficacy Coefficient), which is the core indicator for evaluating luminaire energy efficiency. According to the ErP Energy Labeling Regulation (EU) 2019/2015, energy efficiency classes range from A to G, with 7 classes in total, where Class A is the highest energy efficiency level (best energy efficiency performance) and Class G is the lowest energy efficiency level (poorest energy efficiency performance). Energy efficiency class division is a core component of the ErP Energy Labeling Regulation (EU) 2019/2015, directly affecting product market competitiveness, EU market access, and consumer purchasing decisions.

Significance of Luminous Efficacy Coefficient ƞTM:

• Energy Efficiency Evaluation Standard: Higher ƞTM values indicate greater luminous flux provided at the same power, better energy efficiency performance
• Market Competitiveness: High energy efficiency class (A-B) products are more competitive in the EU market, aligned with green environmental trends
• Consumer Choice: Energy efficiency class directly affects consumer purchasing decisions, high-efficiency products are more favored
• Regulatory Compliance: ErP energy labels are mandatory requirements for EU market access, must be accurately tested and labeled

2.2 Detailed Explanation of Luminous Efficacy Coefficient ƞTM Calculation Formula

The calculation formula for the luminous efficacy coefficient ƞTM is as follows:

Parameter Details:

• Φuse (Useful Luminous Flux): Declared useful luminous flux, unit: lm (lumens). According to ErP Energy Labeling Regulation (EU) 2019/2015, useful luminous flux refers to the luminous flux emitted by the luminaire in normal operating mode that is useful to users. Measurement method complies with EN 13032-1:2004 and CIE 15:2018 standard requirements.
• Pon (Power in Operating Mode): Power in operating mode (on mode), unit: W (watts). Includes light source power and all control device power consumption, but excludes standby power. Measurement method complies with IEC 62384:2006 and IEC 62386 standard requirements.
• FTM (Applicability Factor): Applicability factor, determined according to luminaire type and application scenario. FTM value range is typically 0.85-1.0, specific value depends on luminaire light distribution characteristics, application scenario and standard requirements. Common FTM values: directional luminaires 0.85, non-directional luminaires 1.0.

2.3 Energy Efficiency Class Division Standards and Thresholds

Based on the calculated luminous efficacy coefficient ƞTM value, compare it with the energy efficiency class division standards specified in the ErP Energy Labeling Regulation (EU) 2019/2015 to determine the product's energy efficiency class. Higher energy efficiency classes indicate better energy efficiency performance and lower energy consumption.

Energy Efficiency Class Division Thresholds (ErP Energy Labeling Regulation (EU) 2019/2015):

• Class A: ƞTM ≥ 210 lm/W (Highest efficiency, typical applications: high-end LED luminaires, high-efficiency lighting products)
• Class B: 185 ≤ ƞTM < 210 lm/W (High efficiency, typical applications: quality LED luminaires, commercial lighting)
• Class C: 160 ≤ ƞTM < 185 lm/W (Good efficiency, typical applications: standard LED luminaires, general lighting)
• Class D: 135 ≤ ƞTM < 160 lm/W (Medium efficiency, typical applications: ordinary LED luminaires, basic lighting)
• Class E: 110 ≤ ƞTM < 135 lm/W (Lower efficiency, typical applications: low-end LED luminaires, transitional products)
• Class F: 85 ≤ ƞTM < 110 lm/W (Low efficiency, typical applications: traditional fluorescent lamps, low-efficiency products)
• Class G: ƞTM < 85 lm/W (Lowest efficiency, typical applications: traditional incandescent lamps, obsolete products)

Practical Application Cases:

• Case 1: LED luminaire test results: Φuse = 2000 lm, Pon = 10 W, FTM = 1.0 (non-directional luminaire). Calculation: ƞTM = 2000 / (10 × 1.0) = 200 lm/W. Energy efficiency class: Class B (185 ≤ 200 < 210).
• Case 2: Directional LED spotlight test results: Φuse = 500 lm, Pon = 5 W, FTM = 0.85 (directional luminaire). Calculation: ƞTM = 500 / (5 × 0.85) = 117.6 lm/W. Energy efficiency class: Class E (110 ≤ 117.6 < 135).

Part 3: How Luminaires Obtain ErP Energy Label Certification

To obtain an ErP energy label, the following three steps must be completed. The ErP Energy Labeling Regulation (EU) 2019/2015 specifies the complete certification process for obtaining ErP energy labels, and enterprises must complete ErP energy label certification step by step according to regulatory requirements to ensure products meet EU market access requirements:

Step 1: Conduct ErP Energy Efficiency Testing and Obtain Energy Efficiency Test Report

First, the product must undergo ErP energy efficiency testing to obtain an ErP energy efficiency test report that complies with the ErP Energy Labeling Regulation (EU) 2019/2015 requirements. ErP energy efficiency testing needs to measure key parameters such as useful luminous flux (Φuse, Useful Luminous Flux) and power in operating mode (Pon, Power in Operating Mode), and calculate the luminous efficacy coefficient ƞTM (Luminous Efficacy Coefficient) based on the applicability factor FTM (Applicability Factor), thereby determining the product's energy efficiency class (7 classes from A to G).
