What is the LED voltage?
  This is a problem that many people will consider when choosing lamp beads
After all, the following voltage, current and circuit design, as well as the choice of driving power, are closely related to him.
Voltage drop range for white LED light-emitting diodes: 2.8-.3.5 v
Red LED light-emitting diode voltage voltage drop range: 1.8-2.4 v
Yellow LED voltage drop range: 1.8-2.4 v
Emerald green LED voltage drop range: 2.8-3.4 v
Blue LED light-emitting diode voltage voltage drop range: 2.8-3.4
Of course, it should be noted here that the power of the LED light-emitting diode is related to the current and the current of the LED single chip is constant -20mA
Red, yellow and orange chips are all between 1.8-2.3V, and the rest of the colors are between 2.8-3.6V
In addition, how many volts does the specific LED light up?
The voltage range value of the LED lamp bead is used to select the appropriate driving power; we can look at the LED lamp bead according to the power
0.06w, the power supply is 2.6-3.5 and the current is 20MA
0.5w, the power supply is 2.65-3.77 and the current is 150MA
1w, the power supply is 2.79-3.9v and the current is 350MA
3w, the power supply is 3.0-4.5v and the current is 700MA
5w, the power supply is 3.2-4.9v and the current is 1000MA
The above is the common voltage of LED packaged light-emitting diodes in the LED lamp bead industry. Although there are some white high-voltage lamp beads, such as 6V, 9V, and 18V, they are all for special purposes, such as which products are used for high-voltage lamp belts.
