Beschreibung
Zusammenfassung:	A light-emitting device includes a base member, a plurality of light sources on or above an upper surface of the base member, and a reflector that comprises a plurality of surrounding portions. Each of the plurality of surrounding portions surrounds a respective one of the plurality of light sources in a plan view. Each of the plurality of surrounding portions has inclined lateral surfaces widened upward. Intervals between adjacent ones of the plurality of light sources are constant in the plan view. Upper peripheries of the inclined lateral surfaces of each of the plurality of surrounding portions define an opening having a substantially rectangular shape. The plurality of surrounding portions include a plurality of first surrounding portions and a plurality of second surrounding portions surrounding the plurality of first surrounding portions. An area of the opening of each of the plurality of second surrounding portions is smaller than an area of the opening of each of the plurality of first surrounding portions.
