Re: [PSES] BS EN 62493:2015 Assessment of lighting equipment related to human exposure to electromagnetic fields

[Matthew Wilson]

I looked at the scope of the EN 62493:2015 standard and was confused by a 
statement at the end of section 1 scope on page 9 (of the preview).  It states 
“This standard does not apply to built-in components for luminaires such as 
electronic controlgear.”

What is supposed to be meant by that and why would it not apply?

Electronic controlgear is defined in the standard as

3.1.5
electronic controlgear
mains-supplied a.c./d.c. to a.c./d.c. invertor including stabilizing elements 
for starting and operating one or more lamps, generally at high frequency
Note 1 to entry: All kinds of igniters, starters, switches, dimmers (including 
phase control units e.g. triac, GTO) and sensors are not considered as 
electronic controlgear.

e.g. Say we have a LED ‘table lamp’ which is a luminaire with the AC-DC 
switch-mode power supply for the LED lamp, or perhaps a battery and some 
voltage regulation for the LED, along with some additional circuity to maybe 
dim the LED lamp all built in to the base of the luminaire. The LED in a holder 
above the base, nice shade over it etc. Does that statement in the scope mean 
none of that electronics in the base has to meet the standard?  So if that is 
the case, and all excluded, what exactly is there left to test for 
electromagnetic fields?

Thanks for any help with my confusion.  I’m not being daft am I? (It has been 
known!)

Andy,

   I have not used 62493 so I’m not familiar with the details; I 
looked it up on the IEC website to get an idea as to what it covered and 
reported their summary.

   In reading thru this I see several points here.
1) The broad band radiation up to 300MHz must be for radiated emissions;
2) light itself is very limited in frequency and bandwidth so this must apply 
to the SMPS which are driving the lamps.  Interestingly enough I have seen 
quite robust Touch Current measurements from LED lighting SMPS; which will 
eventually be tamed by proper Touch Current measurements which include the up 
to 1Mhz HF portion allowed by the human body response to HF current.  But note 
that these HF components exist and can give rise to both conducted and radiated 
emissions;
3) SAR measurements indicate radiated emissions which would apply to LED 
systems (including their SMPS) which are worn on or close to the human body in 
their application.

   Perhaps someone else on this thread has more definite insight 
into the application and the need for these requirements; it would be good to 
hear from them.

Thanks yes it is LED so not an issue. Out of interest what type of lighting 
does it cover? The exemption list is quite comprehensive.

Andy,

   Just to clarify:

Abstract; IEC 62493:2015 applies to the assessment of lighting equipment 
related to human exposure to electromagnetic fields. The assessment consists of 
the induced internal electric field for frequencies from 20 kHz to 10 MHz and 
the specific absorption rate (SAR) for frequencies from 100 kHz to 300 MHz 
around lighting equipment. This second edition cancels and replaces the first 
edition published in 2009. This edition constitutes a technical revision. This 
edition includes the following significant technical changes with respect to 
the previous edition:
a) identification of lighting product types deemed to comply with the standard 
without the need for test;
b) deletion of the need for CISPR-15-compliance as a prerequisite for IEC 62493 
compliance;
c) inclusion of the consequences of the ICNIPR 2010 guidelines for (up to 100 
kHz);
d) adding some guidance to the Van der Hoofden test head method to improve 
reproducibility of results;
e) inclusion of compliance demonstration method for products having intentional 
radiators.

   Does your lighting product fall under the exemption?
