《GB/T 36949-2018双端LED灯（替换直管形荧光灯用） 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
1. Background and purpose of the standard
GB/T 36949-2018 standard aims to regulate the performance requirements of double-ended LED lamps (for replacing straight tube fluorescent lamps) to ensure that they can meet technical, safety and environmental protection requirements when replacing traditional fluorescent lamps. The standard was proposed by the China Light Industry Federation and is managed by the National Technical Committee for Standardization of Lighting Appliances.
2. Standard scope and applicable conditions
| Item | Specific requirements |
|---|---|
| Rated power | ${\leqslant}125W$ |
| Frequency | $50Hz$ |
| Rated voltage | AC 220V |
| Nominal length | ${\leqslant}500mm$ |
3. Comparison of standard frameworks
Compared with traditional fluorescent lamps, double-ended LED lamps have significant advantages in the following aspects:
- Luminous efficacy: LED lamps have higher initial luminous efficacy and maintenance rate.
- Lifespan: The median lifespan is not less than $25,000h$, which is much higher than traditional fluorescent lamps.
- Color rendering index: The color rendering index range is wider to meet the needs of different scenarios.
4. Interpretation of technical requirements
The standard clearly specifies the technical indicators of double-ended LED lamps, including:
- Safety requirements: Comply with IEC 62776 standard.
- Electromagnetic compatibility: Meet the requirements of GB/T 17743 and GB 17625.1.
- Life index: The median life is not less than $25,000h$, and there is no early failure.
5. Implementation suggestions
To ensure that the performance of double-ended LED lamps meets the standard requirements, it is recommended that:
- Selection stage: Select products with appropriate luminous flux, light distribution type and color temperature according to specific application scenarios.
- Test verification: Conduct full performance tests according to the test methods specified in the standard to ensure that all indicators meet the standards.
- Quality control: Establish a complete production process quality management system to ensure product consistency.
