Abstract
A lens for controlling an illuminance distribution to realize high luminous flux efficiency by maintaining a required beam angle and uniformity on an illumination surface having a particular shape, such as a square shape, and a light-emitting diode (LED) package including the lens are provided. The lens includes an incidence surface onto which light emitted from a light-emitting device is incident, and an emission surface through which the light incident onto the incidence surface is emitted. An illuminance controller, which includes at least two optical devices, is disposed on the emission surface to control an illuminance distribution of the emission surface.
