In the global trade of LED lighting products, IEC 62471 photobiological safety testing has increasingly become a mandatory market access requirement.Whether for EU CE certification, the IECEE CB scheme, or North American market recognition, an IEC 62471 test report is the authoritative document proving product safety for human eyes and skin.

This article explains IEC 62471, its risk classes, test items, and recommends a top‑tier laboratory:Guangdong Meide Testing Technology Co., Ltd.

1. What is IEC 62471?

IEC 62471 is the international standard titled Photobiological Safety of Lamps and Lamp Systems, published by the International Electrotechnical Commission.It evaluates optical radiation hazards from non‑coherent broadband light sources (including LEDs, excluding lasers) over the 200 nm – 3000 nm range.

1.1 Why It Matters

• Mandatory for LED products entering the EU and many global markets
• Focuses on blue light hazard to the retina (the key concern for general lighting)
• Covers UV, thermal, and infrared radiation risks

1.2 Four Risk Groups

表格

Most general lighting products must meet RG 0 or RG 1.

2. Core Test Items of IEC 62471

1. Photochemical UV hazard (skin & eyes)
2. UVA hazard to eyes
3. Retinal blue light hazard (415–455 nm) – most critical for LEDs
4. Retinal blue light hazard from small sources
5. Retinal thermal hazard
6. Retinal thermal hazard – low visual stimulus
7. Infrared hazard to eyes
8. Skin thermal hazard

Key measured parameters:

• Irradiance (W/m²)
• Radiance (W/m²·sr)

3. Market Value of IEC 62471 Report

3.1 Global Market Access Passport

• EU: Required for CE marking
• CB Scheme: Used for CB certification
