A light emitting diode (LED) illuminant system, a manufacture method thereof, and a backlight module using the same are provided. The LED illuminant system includes a plurality of white light illuminants and at least one green light illuminant mixed in the white light illuminants. A light power ratio of the green light illuminant to the white light illuminants is in between &#x2155; to 1/20. The color temperature of the whole illuminant system will be enhanced to a certain extent by mixing the green light illuminant and the white light illuminants. The manufacture method includes the following steps: obtaining a transmission spectrum of the white light illuminants; analyzing the transmission spectrum to determine n supplemental amount of a green light; and disposing at least one green illuminant in accordance with the supplemental amount of the green light.

Illuminant system using high color temperature light emitting diode and manufacture method thereof

A backlight module includes an optical film set and a plurality of light source sets having a first light source and a second light source. The first light source generates a first chromaticity light while the second light source generates a second chromaticity light. The first chromaticity light mixes with the second chromaticity light in the space between the light source sets and the optical film set and then enters the optical film set. The first chromaticity light and the second chromaticity light have their own spectrum and both spectra fall into a first color region of the CIE 1931 color space. Within the first color region, the spectrum of the first chromaticity light is close to a second color region while the spectrum of the second chromaticity light is close to a third color region.
