Document Type and Number:
WIPO Patent Application WO/2019/088457
Kind Code:
A1
Abstract:
An embodiment relates to an optical lens for changing a path of light emitted from a light source, the optical lens comprising: an exit surface formed convexly upward; a lower surface; and an incident surface formed concavely in the direction of the exit surface from the lower surface, wherein the exit surface includes: a plane having a predetermined radius (R) with respect to an optical axis; a first curved surface extending outwardly from the plane and having a first curvature; a second curved surface extending outwardly from the first curved surface and having a second curvature; and a third curved surface extending outwardly from the second curved surface and having a third curvature. Accordingly, the optical lens can improve light diffusivity by forming a plurality of curved surfaces and planes on the exit surface to change an optical path of a part of the light emitted from the light source.
