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.

Abstract: There are provided a lighting lens, a lighting lens array, and a lighting apparatus. The lighting lens may include an incidence part to receive light from a light source and an emission part to emit light provided from the incidence part. The incidence part may have a concave region that contains a light source and a first protrusion at a rear side of the light source that protrudes downwards from a top surface of the concave region. The emission part may include a dome-shaped part that encloses the incidence part and a second protrusion at the rear side of the light source that protrudes upwards from a top surface of the dome-shaped part. A lowermost portion of the emission part may be formed at a first plane, and an angle between an outer surface of the emission part and the first plane is an obtuse angle.
