The Far Easterners are laughing all over their faces....because the West is trying to copy their doing of parallel leds, without realising that the Far East are adding resistance to the leds.......don't get me wrong, its certain western entrepreneurs who are asking the Far Easterners to do this for them.
I went to a big western lighting place, and they were doing a big panel light using eight parallel strings of eight leds in series (only one overall current source, and no limiting resistors in the led strings)...........they had poor thermal coupling as the leds were so far apart.......they don't realise that just because some prototypes appear to work fine, that doesn't mean it can't go wrong.
