Question 1

IEC 62471 or IEC62778?

Accepted Answer

IEC 62471 and IEC/TR 62778 are both standards for assessing the photobiological safety (light hazards to the eyes and skin) of lighting devices, especially LED lighting. IEC 62471 is a photobiological safety standard applicable to all lamps and lighting systems, covering the assessment of ultraviolet, visible, and infrared radiation hazards, focusing on the photobiological hazard classification of the light source (RG0 - RG3). IEC 62778, on the other hand, focuses on blue light hazard assessment. It only measures and evaluates radiation hazards within the blue light spectrum (380 nm to 780 nm), and this standard is primarily applicable to LED and similar light sources.

Question 2

What is the IEC 62471-2 standard?

Accepted Answer

The full name of IEC 62471-2 is Photobiological safety of lamps and lamp systems-Part 2:Guidance on manufacturing requirements relating to non-laser optical radiation safety. It provides further guidance on the measurement and labeling of sources and is a useful supplement to IEC/EN 62471. According to this standard, we can find the label requirements for different types of photobiological hazards and different Risk Groups.

Question 3

What’s the examples for label requirement as per IEC 62471-2?

Accepted Answer

As per IEC 62471-2 standard, there are label requirement for the light which emit blue light. Take blue light radiance for example, if the lighting products are classified in to Risk Group 0 and 1, there are no label requirements for these two groups. For Risk Group 2, the information should include “CAUTION. Possibly hazardous optical radiation emitted from this product. Do not stare at operating lamp. May be harmful to the eye.” For Risk Group 3, the information should include “WARNING. Possibly hazardous optical radiation emitted from this product. Do not look at operating lamp. Eye injury may result.”
