Foreword

This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This Standard integrates the relevant content of non-directional self-ballast LED lamp; replaces GB 30255-2013 “Minimum allowable values of energy efficiency and energy efficiency grades of non-directional self-ballasted LED-lamps for general lighting services”. Compared with GB 30255-2013, the main technical changes are as follows:

- In the Scope, specify that “This Standard does not apply to indoor lighting LED products with energy-consuming non-lighting additional functions or dimming/toning functions”;

- Modify the luminous efficacy index values of each grade of non-directional self-ballast LED lamps (see 4.1.4);

- Modify the technical requirements for lumen maintenance (see 4.4);

- ADD test methods for correlated color temperature, color rendering index, and lumen maintenance (see 5.3).

This Standard was proposed by and shall be under the jurisdiction of Standardization Administration of the PRC.

Drafting organizations of this Standard: China National Institute of Standardization, Guangdong Dongguan Quality Supervision Testing Center, Shanghai Feilo Acoustics Co., Ltd., Osram (China) Lighting Co., Ltd., Shenzhen Eastfield Lighting Co., Ltd., Hengdian Group Tospo Lighting Co., Ltd., Xiamen Topstar Lighting Co., Ltd., Foshan Electrical and Lighting Co., Ltd., Panasonic Manufacturing (Beijing) Co., Ltd., Shanghai Semiconductor Lighting Engineering Technology Research Center, Philips Lighting (China) Investment Co., Ltd., Shenzhen Spark Co., Ltd., Panasonic R&D Center Suzhou Co., Ltd., Zhejiang Hpwinner Opto Co., Ltd., Hangzhou Woojong Group, Ningbo Yamao Optoelectronics Co., Ltd., Shenzhen Fluence Technology PLC, Beijing Institute of Metrology, Loyal Lighting Co., Ltd., Dongguan Bai Fen Bai Technology Co., Ltd.

Minimum allowable values of energy efficiency and energy efficiency grades of LED products for indoor lighting

1 Scope

This Standard specifies the energy efficiency grades, minimum allowable values of energy efficiency, color rendering index, lumen maintenance, and test methods for LED downlights, directional integrated LED lamps, and non- directional self-ballast LED lamps for indoor lighting.

This Standard applies to LED downlights with LED as the light source, power supply voltage not exceeding AC 250 V, frequency 50 Hz, rated power 2 W and above, beam angle >60°, excluding LED downlights using integrated LED lamps.

This Standard applies to directional integrated LED lamps of PAR16, PAR20, PAR30, PAR38 series with the rated power supply voltage of AC 220 V, frequency 50 Hz, the lamp holder meeting the requirements of GU10, B22, E14, or E27.

This Standard applies to non-directional self-ballast LED lamps with rated supply voltage of AC 220 V, frequency of 50 Hz, rated power greater than or equal to 2 W, less than or equal to 60 W, excluding non-directional self-ballast LED lamps with additional optical lens design.

This Standard does not apply to indoor lighting LED products with energy- consuming non-lighting additional functions or dimming/toning functions.

2 Normative references

GB/T 24824

GB/T 24826

4.2.3 The minimum allowable value of energy efficiency for non-directional self-

ballast LED lamps is Grade 3 in Table 3.

4.3 Color rendering index

The initial general color rendering index Ra of LED downlights, directional integrated LED lamps, and non-directional self-ballast LED lamps shall not be lower than 80. R9 shall be greater than 0. The decrease in the measured value of the color rendering index relative to the rated value shall not be greater than 3.

4.4 Lumen maintenance

The lumen maintenance of LED downlights, directional integrated LED lamps, and non-directional self-ballast LED lamps at 3000 h shall not be lower than the required lumen maintenance associated with the rated life. According to the claimed rated life, the required value of lumen maintenance shall be calculated according to formula (1). Where: LM - Lumen maintenance;

t0 - Rated life, in hours (h).

5 Test methods

5.1 LED downlight

The luminous efficacy, correlated color temperature, and color rendering index of LED downlights shall be tested in accordance with the test methods specified in GB/T 29293.

Based on whether the LED downlight uses an LED package with the LM-80 test report, determine the applicable lumen maintenance test method:

When the LED downlight uses an LED package with the LM-80 test report, after the parameters corresponding to the report are tested, calculated, and verified compliant, the 3000 h lumen maintenance of the LED package in the test report can be used as the 3000 h lumen maintenance of the LED downlight. If verified non-compliant or the LED downlight does not use an LED package with the LM- ......
