Ok all u gurus can hopefully start “taking me to school” on modding drivers.
Here’s my current question:
I have a driver for headlamp that factory is set for 2 emitters in series. Its with the coil (buck?). 2 xm-l2 with 8.4v battery pack. (using my kd2 driver as example basically)
Besides obviously the sense resistor, 1 alone, won’t handle it (my new ss x3 has 5 for a 3x parallel) so multiple paralleled would be needed for idea below:
What other factors of the driver would stop me from running total 4x emitters, 2 parallel strings of 2x in series? ( hope I explained that right)
Based on what ive learned so far: Series= amps constant, voltage drops per emitter. Parallel is vise versa. So parallel strings would get half the amps but maintain voltage, each set in series would keep the emitters operating at the drivers set output voltage. 2 emitters produce more light at half the current than 1 emitter at twice the current.
Besides keeping heat in check, multiple parallel sense resistors to spread the load, what else would be needed to make this work? Not looking for “not an efficient way” and all the more in depth to make it function amazing (not yet), just looking at the basics.
Other question, can u run 2 drivers parallel with one switch that operates both drivers? As in the momentary switch for mode selection? Trying to sort out a monetary switch that would operate both but separetly (so their own switches could be used to program/change mode separately too)
