How many volts does a light emitting diode need to light up?
What is the working voltage of the light emitting diode?
Knowing the voltage drop range of the light-emitting diode, you also know how many volts the light-emitting diode can emit light.
The light-emitting diode can work normally, and the problem of light emission will naturally disappear.
Let's take a look at the operating voltage of the light-emitting diode.
The forward voltage of light-emitting diodes is generally between 1.5 volts and 3.3 volts.
When the outside temperature increases, the voltage value will decrease.
This is characteristic of LED voltage.
At the same time, it is also the electrical parameter characteristics of light-emitting diodes.
Low current, low voltage, environmentally friendly LED characteristics, the LED voltage is destined not to be high.
And the low voltage within 36 volts is a safe voltage.
Such a voltage does not present any danger or harm to the human body.
It means that small current and low voltage can be lit.
Such a lamp bead voltage is the 7th battery, and the 5th battery can light up.
LEDs need a few volts to light up.
2-3 volts.
Usually, the lighting voltage of red light, yellow light, yellow-green light, and orange light is relatively low, about 2 volts.
The lighting voltage of white light, emerald light, blue light, and pink light is relatively high, about 3 volts.
As for the high-voltage light strip, the general LED voltage is 6 volts, 9 volts, 18 volts, and 36 volts to light up.
In the group, people often ask about the voltage drop of light-emitting diodes.
He said, Professor Lamp Bead, what is the general voltage drop of LEDs?
I said, it depends on which color the pressure drop is.
Generally, the voltage drop of different colors of light-emitting diodes is different.
For example, the voltage drop of red light is generally 1.6-2.4 volts.
This voltage drop value is related to the light color, and the voltage drop range is actually the lower and higher voltage range of the color.
Low voltage, the voltage at which the light-emitting diode can light up.
High voltage, the voltage above the rated working voltage of the light-emitting diode.
Often, when we light or work, we work within this voltage.
This is also the reason for the longer working life of light-emitting diodes.
If the value exceeds this range, the light-emitting diode will either not light up, or the light-emitting diode will be easily burned out.
