Abstract: A light-emitting device comprising a lamp casing, a heat dissipation element and a light-emitting module is provided. A first opening and a second opening are formed on an upper end and a lower end of the lamp casing respectively. An edge of the lamp casing adjacent to the first opening is bended inward to form a bending portion. The heat dissipation element has several carrying portions separated from each other and arranged in radial-shape, and several fins perpendicular to the carrying portions. Each fin is bended downward and vertically from an edge of the carrying portions and extended toward the second opening. The light-emitting module comprises a substrate and several light-emitting elements. An edge of the substrate leans against the bending portion, such that the light-emitting module is sandwiched between the carrying portions and the bending portion.

Abstract: The disclosure provides an optical lens including a body. The body includes a light-incident surface and a light-emitting surface. The light-emitting surface is located at an outer surface of the body. The light-incident surface is located at a bottom surface of the body. The body includes a concave portion located at the center of the bottom surface. The concave portion is dented from the bottom surface to the light-emitting surface for accommodating a light source, and the surface of the concave portion is the light-incident surface. The light-emitting surface includes a dented center light-emitting zone and an arc-shaped peripheral light-emitting zone. The dented center light-emitting zone is located at a center zone of the outer surface of the body. The dented center light-emitting zone is aligned with the center of the bottom surface of the body and is indented in a direction toward the light-incident surface.
