Notice!
This product has been tested according to standard IEC62471:2006 "Photobiological safety of
lamps and lamp systems". The product emissions meets the EXEMPT Group limit for Cornea/
Lens infrared hazard as defined by IEC 62471:2006. The product was found to meet the
EXEMPT Group exposure limits for IR LEDs.
The IEC 62471 provides the methods to determine the risk group of any lamp or any product
incorporating a lamp. The risk groups in IEC 62471 indicate the degree of risk from potential
optical radiation hazards. The risk groups were developed based upon decades of lamp use
experience and the analysis of accidental injuries related to optical radiation emission.
EXEMPT Group – no optical hazard is considered reasonably foreseeable, even for
continuous, unrestricted use. Typical examples are most frosted incandescent lamps and
fluorescent lamps used in domestic applications.
Exposure Hazard Value (EHV) is a ratio of the Exposure Level (distance, exposure time) to
Exposure Limit Value (ELV). When EHV is greater than 1, the device has exceeded the
Exposure Limit Values for a particular Risk Group. The ELV is the level where optical radiation
to the eye or skin is not expected to result in adverse biological effects.
The Hazard Distance (HD) is the distance from the source at which the Exposure Level equals
the appropriate ELV. In other words, when EHV=1 for a particular Risk Group.
Regarding the Cornea / Lens infrared hazard of this product, the Exposure Hazard Value (EHV)
at a test distance of 200mm is 2.19 based on EXEMPT Group exposure limits. The EHV based
on Risk Group 1 limits is 0.386. The HD for the Exempt Group is 297 mm.
