What is wavelength of LED light
For the spectral characteristics of LEDs, we mainly look at whether its monochromaticity is good, and we must pay attention to whether the main colors of red, yellow, blue, green, and white LEDs are pure. Because in many occasions, such as traffic signal lights, the color requirements are more stringent. However, it is observed that some of the LED signal lights in our country are blue in green and deep red in red. From this phenomenon, we have conducted special research on the spectral characteristics of LEDs. Very necessary and very meaningful.
