For the purpose of creating/repairing a lighting fixture where one or many LEDs are the only component in a circuit driven by a constant current power supply, is there any benefit to using a series resistor with the LED(s) if the forward voltage after the LED(s) is 0V?
Let's say 5 LEDs, given:
- Power Supply Vout: 14-20V
- Power Supply CC: 350mA
- LED Voltage: 3.2 - 3.4V
- LED rated current: 280 - 350mA
Since the current is being regulated by the power supply itself, and the voltage will match the necessary voltage for the circuit, can the LED(s) be the only components in the circuit and the series resistor omitted?
