发明名称 Aspherical LED lens and light emitting device including the same
摘要 An aspherical lens includes a light entrance plane configured to receive light emitted from a light source and a light exit plane configured to radiate the light received by the light entrance plane. The light exit plane includes semispherical convex portions disposed on an upper surface of the aspherical lens, a concavely depressed portion comprising an overlapping region where the semispherical convex portions partially overlap each other at a central axis, a side portion connected with the semispherical convex portions, and an upper surface of each of the semispherical convex portions having a first flat portion.
