LED Light Colors

different colors of leds

LED lights colors means the light emitted from a light-emitting diode has a specific wavelength and thus a specific color. “Visible light” corresponds to a wavelength range of 400 – 700 nanometers (nm) which correspond to visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. However, it is not difficult to find that there is no white in the color spectrum. Presently, there are two ways to get the white LED lights.

1) Phosphor conversion to make white LED, in which a blue or near-ultraviolet (UV) chip is coated with phosphor(s) to emit white light.

2) RGB systems, in which light from multiple monochromatic LEDs (red, green, and blue) is mixed, resulting in white light.
