Update time : 2026-02-26

iec 62471 is an international standard on photobiological safety of lamps and lamp systems developed by the International Electrotechnical Commission (IEC). Its European version is EN 62471, and the equivalent standard adopted in China is GB/T 20145-2006. This standard aims to assess the optical radiation hazards that light sources may pose to human eyes and skin, and is widely used in the safety evaluation of LED lighting, display equipment, luminaires, and other non-laser light source products.

Introduction to IEC 62471 Standard

①　Full Standard Name: IEC/EN 62471 Photobiological Safety of Lamps and Lamp Systems

②　Scope: Applicable to all lamps and lamp systems except lasers, including LED lamps, fluorescent lamps, halogen lamps, projectors, display screens, automotive lamps, etc.

③　Wavelength Range: Covers 200 nm to 3000 nm, including ultraviolet (UV), visible light, and infrared (IR) bands.

④　Core Purpose: Replaces the laser class requirements for LED products in the old standard IEC/EN 60825 and introduces a more comprehensive photobiological safety evaluation system.

⑤　Implementation Status:

a. EU standard EN 62471:2008 has been mandatory since September 1, 2009.

b. The provisions of iec 60825 related to LEDs have been invalidated.

Test Content and Hazard Assessment Objects of IEC 62471

The standard assesses the following 8 categories of photobiological hazards by measuring parameters such as irradiance (W/m²) and radiance (W/m²·sr):

Test Item	Wavelength Range	Hazard Target	Description
1. Ultraviolet hazard to skin and eyes	200–400 nm	Skin, cornea, lens	Long-term exposure may cause sunburn and cataracts
2. Near-ultraviolet hazard to eyes (UVA)	315–400 nm	Retina	May cause photochemical damage to the retina
3. Retinal blue light hazard	300–700 nm	Retina	Blue light (400–500 nm) easily induces oxidative damage to the retina
4. Retinal blue light hazard (small sources)	300–700 nm	Retina	For small-area high-brightness light sources (e.g., LED point sources), with stricter assessment
5. Retinal thermal hazard	380–1400 nm	Retina	Strong light causes local temperature rise, resulting in thermal damage
6. Retinal thermal hazard (weak visual stimulus)	780–1400 nm	Retina	Vision is insensitive under infrared light, but thermal effects still exist
7. Infrared radiation hazard to eyes	780–3000 nm	Lens, cornea	Long-term exposure may cause "glassblower’s cataract"
8. Skin thermal hazard	380–3000 nm	Skin	High-intensity radiation causes skin burns

IEC 62471 Test Report

Hazard Group Classification (Risk Groups, RG)

According to test results, products are classified into four risk groups:

Grade	Name	Safety Description
RG0	Exempt	No hazard, safe under all conditions
RG1	Low Risk	No risk under normal use; may be harmful after prolonged direct viewing
RG2	Moderate Risk	Do not look directly with naked eyes; may be harmful even after short exposure
RG3	High Risk	May cause injury even with instantaneous exposure; strict protection required

Note: Most consumer lighting products should meet RG0 or RG1 level.

IEC 62471 Report Application Process

IEC 62471 test reports are usually issued by third-party testing organizations. The process is as follows:

① Consultation and Confirmation

Contact a qualified testing organization to confirm the test standard (IEC/EN/GB), test items, and fees.

② Preparation of Documents and Samples

a. Product manual or user guide

b. Product model difference list (for multiple models)

c. List of key components (e.g., LED chips, lenses, driver power supplies)

d. PCB design drawings (front and back sides)

e. Application form (provided by the testing organization)

f. Test samples: Generally 1–2 sets of complete finished products.

③ Sample Submission

Send the samples and documents to the JJR laboratory.

④ Laboratory Testing

Measurements are performed in a dark room using calibrated spectroradiometers at a specified distance (usually 200 mm or calculated based on light source size).

Irradiance and radiance are tested, and hazard values for each band are calculated.

⑤ Report Issuance

a. Testing period: 5–7 working days (ordinary products); may be extended for complex products.

b. Report content includes: test parameters, results, hazard group judgment, compliance with the standard, etc.

⑥ get Formal Report

After the report is approved, the organization issues a formal IEC 62471 test report (with CMA, CNAS and other qualification stamps, depending on usage).

Frequently Asked Questions

Q1: Is factory inspection required for EN 62471 certification?

No. IEC/EN 62471 is a product type test, which is only responsible for the submitted samples and does not involve factory audit.

Q2: Which products need to comply with IEC 62471?

All non-laser light source products, especially:

①　LED luminaires (bulbs, downlights, panel lights, etc.)

②　Display screens (LED large screens, Mini/Micro LED)

③　Automotive lighting (headlights, ambient lights)

④　Medical lighting (surgical lamps, dental lamps)

⑤　Consumer electronics (mobile phone flashlights, projectors)

Q3: What is the difference between IEC 62471 and IEC/TR 62778?

①　IEC 62471: A comprehensive photobiological safety test standard including multi-band hazard assessment.

②　IEC/TR 62778: A supplement to IEC 62471, dedicated to assessing the blue light hazard of LED light sources. It quickly judges the risk level based on light source spectral data and is often used for pre-evaluation during product design.
