There are various ways to distinguish the colors of LED chips, but the most common is through letter markings. For example, R represents red, G represents green, B represents blue, A represents white, W represents yellow, and Z represents purple.
Specifically, red chips are usually marked R on the circuit board, green chips G, and blue chips B. White chips are usually marked A, yellow chips W, and purple chips Z. This letter marking method is simple, clear, and easy to identify quickly.
In addition, the spectral characteristics of LED chips are also an important basis for distinguishing colors. The peak wavelength of red LED chips is typically between 620-700 nanometers, green LED chips between 500-530 nanometers, and blue LED chips around 450-470 nanometers. White LED chips consist of blue LEDs and yellow phosphors, while yellow LED chips have a peak wavelength of approximately 570-590 nanometers. Purple LED chips have a peak wavelength of approximately 380-450 nanometers.
It is worth noting that the color of LED chips can also be distinguished by their color temperature. Generally, color temperatures above 5000K are considered cool colors, such as blue and white, while color temperatures below 3000K are considered warm colors, such as red and yellow. Purple LED beads have a color temperature between these two extremes.
Understanding how LED bead colors are differentiated allows for better selection of colors to meet the needs of various applications. Whether for home lighting or commercial displays, choosing the right LED bead color can add different atmospheres and aesthetics to the environment.
