"Driverless LED ...":
Not as big as it sounds: One has to be aware that LEDs without drivers operated directly to alternating voltage will flicker with it's maximum or stroboscope-like.
According to DIN EN 12464-1 / -2, stroboscopic flicker must be avoided at workplaces.
According to the new Eco Design directive the amount of flicker of these lamps will not be allowed in future any more.
You should in any case obtain information about the light flicker from your vendor.
The assertion of flicker-free can not be correct for illuminants that flicker more than the incandescent bulb. Here is the list of marketers who still do.
On 16./17. In April, a working meeting of the International Electrotechnical Commission
IEC TC34 WG5 took place in the Osram-Lighthouse, Munich, which was scheduled for 30 members from 13
nations. Der Lichtpeter was also invited to this meeting and presented the CFD and the TLA as a combination of PstLM and SVM.
The top experts of this round agreed: Technically, the procedures are flawless and well worked out.
By 12-Feb-2018, 5pm: LiTG: Lecture "Flicker on light sources" at KIT Karlsruhe (DE).
22-Feb-2018: Interview with the magazine LiCHT, Munich: Lightflicker (DE)
15-Nov-2017: On the Website Open Forum in EuP
Network Germany there is to read:
"Product properties: Light flicker: Discussion text by Peter Erwin".
In the latest issue of the US LEDs Magazine, an article has been published in which Peter Shackle
and Der Lichtpeter present the CFD as the only suitable measurement for complex periodic light signals.
