Photobiological Safety Testing & Risk Assessment

Comprehensive Assessment of Radiation Hazards to the Human Eye and Skin from Light Source Products – In Accordance with IEC 62471 / EN 62471 / GB/T 20145 International and National Standards

I. What is Photobiological Safety Testing?

1. Authoritative Definition

Photobiological safety testing is a systematic assessment of all potential photochemical and thermal hazards that an optically radiating light source (non‑laser) may cause to the eyes (e.g., retinal blue light hazard, ultraviolet photokeratitis) and skin (e.g., erythema). The core is to classify the product into Exempt Group, Risk Group 1 (low risk), Risk Group 2 (moderate risk), or Risk Group 3 (high risk) according to the standards.

2. Core Value

• (1) Scientifically Quantified Risk
  Go beyond subjective perception – quantify the optical radiation safety level of your product with data, providing scientific support for product design and marketing.

• (2) Mitigate Legal Risks
  Eliminate legal disputes and large claims caused by blue light, ultraviolet, or other radiation hazards from light source products (e.g., LED luminaires, displays) at the source.

• (3) Facilitate Global Market Access
  IEC 62471 is a fundamental and mandatory safety requirement for luminaires and lamp systems in many countries and regions, including the EU (EN 62471) and North America (incorporated into ANSI/IES RP‑27).

II. What You Need to Know About Photobiological Safety Testing

Q: Which products require photobiological safety testing?
A: Almost all powered light source products, especially:

• LED luminaires, bulbs, and modules

• Various displays (mobile phones, computers, televisions)

• Projectors, stage lights, ultraviolet disinfection lamps

• Beauty lamps, intense pulsed light (IPL) beauty devices

Q: What are the core testing items?
A: Mainly evaluate irradiance and radiance, including:

• Retinal blue light hazard

• Ultraviolet hazard (to eyes and skin)

• Retinal thermal hazard

• Infrared radiation hazard to the eyes

• Skin thermal hazard

Q: What documents are required for certification?
A: Testing application form, product specification sheet, product information, company information, etc.

Q: What is the process and timeline for certification?
A: Submit product information → Evaluation and quotation → Sample testing → Issue compliance report → After‑sales service (completed).
Timeline: Typically within 7 working days after all documents are ready.
