Abstract
A light emitting module includes: a light source; a first lens disposed above the light source; and a second lens disposed above the first lens. The first lens includes: a lower face including a first convex face projecting towards the light source, and an upper face including a second convex face projecting towards the second lens. In a top view, an area of the second convex face is smaller than an area of the first convex face. At least one of an upper face or a lower of the second lens includes a concave face.
