The optical lens includes a bottom surface having a recess part at center thereof; a light exit surface provided in opposite to the bottom surface and having a convex curved surface; an outer sidewall connected between the bottom surface and the light exit surface; a recess portion recessed toward the bottom surface; and a convex portion provided between the recess portion and the light exit surface. The recess part is convexly recessed in a direction of the recess portion. The recess portion includes a first to third total-reflection surface having curvatures different from each other. The convex portion is protruded inwardly from an inflection point between the convex portion and the light exit surface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical lens, light emitting device, and lighting device having the same","description":"Disclosed is an optical lens.
