Abstract: A light source device includes: a combined body comprising light emitting portions including: a first light emitting portion comprising a first light emitting element, and a second light emitting portion provided separately from and along an outer periphery of the first light emitting portion in a plan view, the second light emitting portion comprising a plurality of second light emitting elements; and a lens disposed above the combined body. The first light emitting element and the plurality of second light emitting elements are arrayed in first and second directions that are perpendicular to each other. The first light emitting element and the plurality of second light emitting elements are controllable to be lit independently.

Abstract: A light-emitting device includes: a plurality of light-emitting elements arranged in an array on a base member; and a compound eye lens that includes a plurality of lens parts disposed above the base member and facing the plurality of light-emitting elements. The plurality of light-emitting elements are arranged such that each of the plurality of light-emitting elements faces a corresponding one of the lens parts, and a center of each of the plurality of light-emitting elements is offset from a lens center of the corresponding one of the lens parts of the compound eye lens in a direction toward a center of the compound eye lens in a plan view. The plurality of light-emitting elements include first light-emitting elements and second light-emitting elements that are alternately arranged, wherein an emission color of the first light-emitting elements is different from an emission color of the second light-emitting elements.

Abstract: A light-emitting module including a substrate, a light-emitting device disposed on the substrate, a lens, and an optical sensor. The light-emitting device includes at least one light-emitting element and a light-transmissive member disposed on a light extraction surface of the at least one light-emitting element. The lens is disposed apart from the light-emitting device at a position where the lens faces the light-emitting device. The optical sensor has an upper surface including a light-receiving surface to receive light through the lens and is disposed on the substrate at a position where at least a part of the light-receiving surface faces the lens. A center of the light-emitting device is located at a center of the lens in a plan view.
