The solid-state light-emitting devices and the light-incoupling component are configured on the carrier. The light-incoupling component has a bottom surface, a top surface, a plurality of side surfaces adjoining the bottom surface and the top surface, and a through hole extending from the bottom surface to the top surface. The solid-state light-emitting devices are located in the through hole. The first reflector covers the through hole. The second reflectors are configured on the side surfaces. Light emitted from the solid-state light-emitting devices enters the light-incoupling component via a sidewall of the through hole and leaves the light-incoupling component via the top surface thereof.
