I. Essential Documents for CE Certification of LED Fixed Luminaires

To ensure a smooth and efficient CE certification process, enterprises need to prepare the following core documents:

1. Certification Application Form

• Provide complete basic information about the enterprise and products.
• Clarify the certification scope and product classification.

2. Product Installation Manual

• Include detailed multi-language installation instructions.
• Safety warnings and usage precautions.
• Labeling instructions meeting EU market requirements.

3. Model List

• List all models and specifications applying for certification.
• Clearly outline the differences between each model.

4. CDF (Component Declaration Form) – Key Components List

• Detail the model, specifications of all key components.
• Provide relevant certification certificate numbers.
• Include core components such as LED chips, drivers, and housings.

5. LED Chip Specifications

• Complete photoelectric parameter characteristics.
• Supplier information and technical support documents.

6. Product Nameplate

• Complete nameplate design complying with CE marking requirements.
• Include all necessary electrical parameters and certification marks.

II. Key Requirements for SELV Circuit Certification in LED Drivers

In the CE certification of LED driver products, the design compliance of SELV circuits is a key focus of technical review.

Core Definition of SELV Circuits

A SELV (Safety Extra-Low Voltage) circuit refers to an extra-low voltage circuit with effective isolation from the mains power supply. This isolation must ensure:

• Sufficient insulation strength between primary and secondary circuits.
• Isolation performance meeting the relevant standard requirements for safety isolation transformers.

Electrical Parameter Limit Requirements

Whether under full-load or no-load operating conditions, the output voltage of SELV circuits must meet the following strict limits:

• AC output voltage: ≤50V (rms).
• DC output voltage: ≤120V (ripple-free).

Insulation Design Requirements

The isolation insulation strength of SELV circuits must at least meet the insulation requirements between primary and secondary windings of safety isolation transformers specified in IEC 61558-2-6, which is a key technical indicator to ensure product safety.

III. Certification Preparation Recommendations

Document Preparation Key Points

• Ensure all documents are accurate and complete.
• Technical parameters must be consistent with actual samples.
• Conduct internal review and verification in advance.

Technical Support Guarantee

It is recommended that enterprises make adequate technical preparations before formal application. If necessary, seek pre-evaluation services from professional testing institutions to ensure product design meets relevant standard requirements.

By improving document preparation and strictly controlling key technical points such as SELV circuits, enterprises can significantly improve the pass efficiency of CE certification for LED fixed luminaires, laying a solid foundation for products to smoothly enter the EU market.
