I am trying to connect, in parallel, 18 LEDs that have these specs:
LED
- size: 10mm;
- Voltage: 3.2V - 3.4V;
- Current: 20mA.
Driver
- Type/Model: MeanWell LPC-20-350 (datasheet: http://www.meanwell.com/search/lpc-20/LPC-20-spec.pdf)
From my calculation, by putting 18 LEDs in parallel I need a total current of 360mA, so by driving a (max) current of 350mA i do not need a resistor (to limit the current) and it should not burn the LEDs, however after a blink they all burned.
What am i missing?
