Abstract
A white color light source of an organic light emitting diode is provided and is suitable for irradiating on plants. The white color light source includes a first color light and a second color light. A peak in the frequency spectrum of the first color light is within a first wavelength range. A peak in the frequency spectrum of the second color light is within a second wavelength range. The white color light source is at least formed by mixing the first color light and the second color light, wherein an intensity of a frequency spectrum of a wavelength range from 520 nm to 580 nm is substantially equal to or less than 20% of a total intensity of a frequency spectrum of the white color light source.
