Variable Voltage Led at moisesmjohnsono blog

Variable Voltage Led. constant current led drivers have a fixed current in amperes or milliamperes and a variable voltage. by combining different control modes, it is possible for an led driver to have both constant current across a variable voltage and constant voltage.

the “ light emitting diode ” or led as it is more commonly called, is basically just a specialised type of diode. The voltage only needs to be slightly above the forward. If you want to control the brightness of a led, you need to control the current flowing through it.

Variable Voltage Led If you want to control the brightness of a led, you need to control the current flowing through it. constant current led drivers have a fixed current in amperes or milliamperes and a variable voltage. If you want to control the brightness of a led, you need to control the current flowing through it. standard red, green, and yellow leds have forward voltages in the range 1.4v to 2.6v, depending on the desired.
