A lighting device includes a base, a light emitting component operable to generate light, and a light control component cooperating with the base to enclose the light emitting component. The light control component includes a light transmissive body that has a datum point, a main axis passing through the datum point, a light incident surface that is axis symmetrical relative to the main axis, and a light exit surface that is axis symmetrical relative to the main axis. The light incident surface includes a plurality of annular incident surface portions that form a Fresnel lens configuration and that are concentric with respect to the main axis.
