《GB/T 24827-2015道路与街路照明灯具性能要求》由TC224（全国照明电器标准化技术委员会）归口，TC224SC2（全国照明电器标准化技术委员会灯具分会）执行，主管部门为中国轻工业联合会。
本标准规定了使用电光源、电源电压不超过1000V 的道路与街路照明灯具的性能要求、试验方法及检验规则。
本标准适用于城市道路与街路使用的道路与街路照明灯具。
本标准不适用于隧道照明灯具。
Introduction
Overview of the core content of the standard
GB/T 24827-2015 replaces the 2009 version and specifies the performance requirements for electric light source road and street lighting fixtures. It is applicable to urban lighting scenarios with a voltage of ≤1000V, and explicitly excludes tunnel lighting. The standard focuses on three dimensions: optical performance, energy saving index and durability test.
Definition of key terms
| Term | Definition | Associated parameters |
|---|---|---|
| Light output ratio (LOR) | Ratio of total luminous flux of lamps to standard luminous flux of light source | ≥70% (Class B) |
| Lighting power density (LPD) | Installation power per unit road surface area | Must comply with CJJ45-2006 limit |
| Outdoor Luminaire Classification System (LCS) | Light distribution solid angle evaluation system | Front light/back light/upward light classification |
Comparison of technical requirements (Grade A vs. Grade B)
- Power factor: electronic ballast Grade A ≥0.95, Grade B ≥0.90
- Protection level: light source cavity Grade A IP65, Grade B IP55
- Light output ratio: Grade A ≥75%, Grade B ≥70%
- Vibration resistance requirements: Grade A is mandatory, Grade B is not required
- Light source cavity protection: Grade A IP65, Grade B IP44
Essence of test methods
Vibration test: According to the application scenario of the lamp (road/bridge), select the acceleration level (1.5g~3.5g), and perform 100,000 vibration tests at the resonant frequency. The structural integrity is the qualified standard.
Photometric measurement: According to GB/T 9468, the (C,γ) coordinate system is used to calculate the road surface brightness/illuminance uniformity. The threshold increment (TI) must be ≤10% (expressway).
Implementation recommendations
- Prioritize the use of Class A lamps to meet the needs of high-level road lighting
- The light pollution risk needs to be assessed through the LCS system during the design phase
- Regularly maintain and check the seals (temperature limit of silicone rubber material -20℃)
