A street light source assembly includes a number of spaced solid state light emitting elements for emitting light beams, a number of first light diverging members, and a number of second light diverging members. Each of the first diverging members comprises a first concave light incident surface facing the respective one of the solid state light emitting elements. Each of the second diverging members comprises a second concave light incident surface facing the respective one of the first light diverging members. A radius of curvature of each the second concave light incident surface is larger than that of the corresponding first concave light incident surface. The second light diverging members are aligned with the respective first light diverging members and the respective solid state light emitting elements.
