The Guangdong Provincial Bureau of Quality Supervision released the results of supervision and spot checks. Spot checks of 51 batches of LED street lamps and light source controllers revealed that 20 batches were unqualified and the rate of discovery of unqualified products was 39.2%. In the list of unqualified companies and products that were notified, a number of companies were included in the list of “Green Lighting Demonstration City Street Lamp Recommended Products for Purchasing Products†last year.
Among the unqualified LED street lamps and light source controllers that were spot checked, there were many unqualified dust and water proofs, involving six batches. External wiring and internal wiring were unqualified and involved 7 batches.
The spot check is based on DB 44/T 609-2009 "LED Street Lights", GB 7000.5-2005 "Safety Requirements for Roads and Street Lighting Fixtures", GB 7000.1-2007 "Luminaires Part 1: General Requirements and Tests", GB 19510.1-2009 "Lamp control devices - Part 1: General requirements and safety requirements", GB 19510.14-2009 "Lamp control devices - Part 14: Particular requirements for DC or AC electronic control devices for LED modules", GB 17743-2007, "Electrical lighting Limits and Measurement Methods for Radio Disturbance Characteristics of Radio and Similar Devices, GB 17625.1-2003 Electromagnetic Compatibility Limit Harmonic Current Emission Limit (equipment input current per phase ≤ 16A), GB/T 17626.5-2008, Electromagnetic Compatibility Test And measurement technology surging (impact) immunity test and the current effective corporate standards and product quality indicators and requirements for the classification, marking, structure, creepage distance and clearance, and grounding requirements for LED street lamps , terminal blocks, external wiring and internal wiring, protection against electric shock, durability test and thermal test, dust and water resistance, insulation resistance and electric strength, heat resistance, fire resistance, and tracking resistance, electricity Source terminal disturbance voltage, radiated electromagnetic disturbance (9kHz-30MHz), radiated electromagnetic disturbance (30MHz-300MHz), harmonic current emission, surge immunity, appearance detection, electrical performance of the lamp, protection class, maximum temperature, LED street lamp initial 25 items such as light efficiency, average display index, spot shape, and light distribution curve were examined; as well as classification, signs, terminal blocks, protective grounding devices for LED street light source controllers, measures for preventing accidental contact with live parts, and moisture protection. Insulation, dielectric strength, fault conditions, abnormal conditions, structure, creepage distances and clearances, screws, current-carrying parts and connections, heat resistance, fire and trace resistance, corrosion resistance, power terminal disturbance voltage, radiated electromagnetic Harmful (9kHz-30MHz), radiated electromagnetic disturbance (30kHz-300MHz), harmonic current emission and other 18 items were examined.
Spot checks found that 20 batches of products do not meet the requirements of the standard, involving structure, grounding regulations, external wiring and internal wiring, dust and water, insulation resistance and electrical strength, heat resistance, fire resistance and tracking resistance, power terminal disturbance voltage, Radiated electromagnetic disturbance (30MHz-300MHz), harmonic current emission, surge immunity, electrical properties of the lamps, protection class, average color rendering index, light distribution curve and other items.
