《GB/T 39008-2020双端集成式LED灯 性能要求》由TC224（全国照明电器标准化技术委员会）归口，TC224SC1（全国照明电器标准化技术委员会电光源及其附件分会）执行，主管部门为中国轻工业联合会。
Introduction
Analysis of the core content of the standard
| Technical dimensions | Wide beam type (W) | Narrow beam type (N) |
|---|---|---|
| Beam angle requirements | ≥180° | 120°-180° |
| Central light intensity | Must meet the requirements of symmetry of the light distribution curve | |
Key technical requirements
Luminous efficiency level: It is divided into three levels according to the color temperature. The maximum requirement for 6500K color temperature products is 120lm/W (Grade I)
Lifetime indicators: Average lifespan ≥ 15000h, 6000h lumen maintenance rate ≥ 86.7%
Implementation suggestions
1. Model marking specification: Adopt the IPT2000-N865G13·1200 five-section structure
2. Electromagnetic compatibility design: Must meet the requirements of GB/T17743 and GB17625.1 at the same time
Standard evolution analysis
This standard compares the technical requirements of LED lamps with those of traditional fluorescent lamps for the first time, introduces the TM-21 life prediction method, and fills the gap in the national standard for integrated LED lamps
