Appraisal of the Photobiological Safety of LED Light Units for Machine Vision

1.Appraisal of the Photobiological Safety of LED Light Units for Machine Vision


In 2006, the International Electrotechnical Commission published IEC 62471, Photobiological Safety of Lamps and Lamp Systems. LED light sources are within the scope of this regulation.
IEC 62471 is a guideline for appraising photobiological safety. This international standard is used to appraise the risk of light on skin, eyeballs, and other parts of the human body.
Photobiological risks are classified into four risk groups according to the degree of biological harm.

CCS classifies the risk of LED Light Units for machine vision for the following appraisal items.
(Applicable standard: IEC 62471:2006 (Edition 1.0))


*Appraisal Items
Photobiological Risk
1. Damage to eyes from near ultraviolet radiation
2. Damage to retina from blue light
3. Damage to retina from blue light from small light sources
4. Thermal damage to retina
5. Thermal damage to retina from low-visibility light
6. Damage to eyes from infrared radiation
7. Thermal damage to skin


Risk Classifications
1. Exempt: Light sources that do not present any photobiological hazard
2. Low risk: Light sources that do not present any photobiological hazard under normal behavioral limitations
3. Mod risk: Light sources that do not present any photobiological hazard due to aversion response to bright light or thermal discomfort
4. High risk: Light sources that are hazardous even for momentary exposure


2. CCS Initiatives


CCS performs risk classification of all of our Light Units to ensure that they can be used safely.
To check the risk information for a Light Unit that you are considering for purchase or have already purchased, refer to the specifications for the specific Light Unit.
