What's the difference between LED and LED? Are the lanterns hung during the Spring Festival LED? How many volts does an LED need? What is the principle?
LED and light emitting diode are the same thing, but the former is an English abbreviation and the latter refers to Chinese translation. The working voltage of LEDs with different colors is different. Generally red is about 1.8V, green is about 2V, and blue and white are higher, about 3V. Voltage is not important, working current is important. Non-luminous led should be controlled at about 10mA, while luminous LED has a large current, so it needs to be checked online according to the model.
