In fact, in the industry, the first three categories are the voltage values of conventional light-emitting diodes. In fact, because of the wide range of applications of LED products, many customers still have special requirements for the voltage of light-emitting diodes, such as high-voltage lamp beads:
High-voltage high-power SMD LED: 6V, 9V, 12V, 18V, 24V, 36V, 48V, 72V (special high voltage)
Integrated high-power light-emitting diode: 9-72V (10W, 20W, 30W, 50W, 100W, 300W, 500W power size is different, series and parallel are different, voltage value is different)
COB high-power lamp beads: 9-72V (power size, current, package size is different, series and parallel methods are different, voltage is different for each series)
In fact, these high-pressure lamp beads are mainly used to illuminate home or commercial lighting products, such as spotlights, ceiling lights, downlights, street lights or high bay lights. Therefore, this kind of lamp beads generally have clear voltage and current parameter requirements from customers. Therefore, we refer to the parameters on the demand to match the corresponding LED voltage lamp beads.
Final words

Knowing the voltage of various color LED light-emitting diodes is very helpful for customers' LED light-emitting diode selection. In addition, in the LED selection, there is also a light-emitting diode voltage parameter that is also very important, that is, luminescence. The voltage drop of the diode.
What is the general voltage drop of commonly used LEDs of various colors?
Red light is generally 1.6-1.8V

Green emerald light generally has a voltage drop of 3.0V
Yellow light is generally 2.0V
Orange light is generally 2.2V
Blue light is generally 3.0V

Attached LED light-emitting diode knowledge:
The color of light-emitting diodes: Light-emitting diodes can adjust the energy band structure and forbidden band width of materials through chemical modification methods to achieve red, yellow, green, blue, and orange multi-color light emission. Because the working voltage of the red light-emitting diode is relatively small, the working voltage of the red, orange, yellow, green, and blue light-emitting diodes of different colors increases sequentially.
LED voltage:
Compared with traditional incandescent bulbs and neon lamps, LED light-emitting diodes are characterized by: low working voltage (for example, only 1.6 volts for red light); low working current (some only a few tenths of a milliamp can emit light); Good impact resistance and earthquake resistance, high reliability, and long life; the intensity of light can be easily modulated by modulating the strength of the current passing through. This is the reason why light-emitting diodes are more and more widely used.
At the same time, with the continuous improvement of LED packaging technology, the scope of LED applications will of course become wider and wider. Let us look forward to the advancement of science and technology, which will continue to bring us a better life.
