Lens and light emitting module for surface illumination

摘要

Disclosed herein is a lens and light emitting module for surface illumination. The light emitting module includes a circuit board; a light emitting device mounted on the circuit board; and a lens dispersing light emitted from the light emitting device. The lens includes a lower surface formed with a concave section defining a light incident surface through which light enters the lens, an upper surface through which light exits the lens, and legs coupled to the circuit board and disposed farther outside the lens than an area of the upper surface. The light emitting device is disposed within the concave section of the lens. With this structure, the lens and the light emitting module can be reduced in thickness.
