Abstract:
A lighting module disclosed in an embodiment comprises: a plurality of light-emitting elements on a substrate; and a reflector arranged in the direction of emission of light from each light-emitting element on the substrate. The light-emitting element has a light emission surface, and the reflector has a reflecting surface concave toward the substrate, at least a part of the reflecting surface corresponding to the light emission surface of the light-emitting element. The reflecting surface is arranged at a height that increases gradually in proportion to the distance from the light-emitting element arranged in the light incident direction. The reflecting surface comprises a plurality of convex portions arranged in a first direction and first bridge portions that connect between the plurality of convex portions. The first bridge portions are arranged along the convex portions and are arranged to be lower than a straight line that connect high points of adjacent convex portions. The convex portions and the first bridge portions have the same length in a second direction, which is perpendicular to the first direction, and the area of the convex portions may be larger than the area of the first bridge portions.
