Abstract:
A light-emitting device includes: a plurality of light-emitting elements arranged in an array on a base member; and a lens that comprises at least four Fresnel lenses disposed above the base member and facing the plurality of light-emitting elements. In a top plan view, a center of each of the plurality of light-emitting elements is offset from a lens center of the corresponding one of the Fresnel lenses of the lens in a direction toward a center of the lens. The plurality of light-emitting elements include at least two first light-emitting elements and at least two second light-emitting elements, wherein an emission color of the first light-emitting elements is different from an emission color of the second light-emitting elements.
