Abstract
A laser light source (), a wavelength conversion light source, a light combining light source, and a projection system. The laser light source comprises a laser element array, a focusing optical element (), a collimation optical element (), an integrator rod () for receiving and homogenizing a secondary laser beam array (), an angular distribution control element () disposed on the light path between the laser element array and the integrator rod () for enlarging the divergence angle of the laser beam array () in the direction of the short axis of the light distribution, such that the rate between the divergence angle of each of the secondary laser beam that enters the integrator rod () in the direction of the short axis of the light distribution and the divergence angle in the direction of the long axis is greater than or equal to 0.7.
