ABSTRACT:
Disclosed herein is a Light Emitting Diode (LED) light source lens for emitting light in a lateral direction. The LED source lens includes an upper part, an upper part and a central part. The upper part includes an upper part reflecting surface bent symmetrically with respect to the central axis of the lens, and an upper part refracting surface extended from the end of the upper part reflecting surface parallel with the central axis. The central part includes a side surface extended from the lower end of the upper part refracting surface and bend inwards, and refracts or reflects light through the side surface. The lower part accommodates the LED light source, and includes an arch-shaped lower part refracting surface extended outwards from the lower end of the side surface of the central part. The light radiated from the LED light source is emitted perpendicular to the central axis.
