1. A method for making a lighting module for preventing glare and providing adjustable color temperature comprising the steps of:
- providing a carrier;
connecting red light-emitting diode packages to the carrier, each of the red light-emitting diode packages comprising a red light-emitting diode chip, a cover for covering the red light-emitting diode chip and scattering particles scattered in the cover;
connecting green light-emitting diode packages to the carrier, each of the green light-emitting diode packages comprising a green light-emitting diode chip, a cover for covering the green light-emitting diode chip and scattering particles scattered in the cover; and
connecting blue light-emitting diode packages to the carrier, each of the blue light-emitting diode packages comprising a blue light-emitting diode chip, a cover for covering the blue light-emitting diode chip and scattering particles scattered in the cover, wherein the numbers and positions of all of the light-emitting diode packages on the carrier are changeable to adjust the color temperature of light emitted from the lighting module and therefore prevent glare;
providing a cover for covering the red light-emitting diode packages, the green light-emitting diode packages and the blue light-emitting diode packages.

Abstract
Disclosed is an illuminative module for enhancing the white balance while reducing thermal drift and color blocks. The illuminative module includes a substrate and light-emitting elements provided on the substrate to emitting light of the primary colors and a fourth color, respectively, so that the light of the primary colors is mixed with the light of the fourth color to provide white light.
