A solid-state light source includes a substrate, a solid-state light-emitting chip, a plurality of micro-members and a light-permeable encapsulation. The substrate has a substantially flat surface. The solid-state light-emitting chip is arranged on the substantially flat surface of the substrate and electrically connected to the substrate. The micro-members are arranged on the surface of the substrate and parallel with the solid-state light emitting chip. The light-permeable encapsulation is arranged on the surface of the substrate and covers the solid-state light-emitting chip and the micro-members.
