Abstract
In this paper, a scheme of laser-driven white light illumination based on diffuse reflection is proposed, which can effectively avoid the blue spot phenomenon. The white light with color temperature of 4717 K, lumen of 9.705 lm and color rendering index of 62 can be obtained by using the illumination module with 0.05 W blue laser excitation, which is consistent with the theoretical calculation results. We propose two methods to improve the white light uniformity, namely hook face and concentration gradient.
