ABSTRACT:
The present invention relates to an LED lens, in which a planar bottom has a pair of halves symmetrically connected with each other about a reference line and narrowed in the vicinity of the reference line. A pair of substantially semicircular reflecting surfaces are extended from both edges of the bottom connected with both ends of the reference line. A radiating surface is connected with remaining edges of the bottom and semicircular edges of the reflecting surfaces. The reflecting surfaces reflect light beams are introduced from the LED chip through the bottom toward the radiating surface. The radiating surface radiates the light beams to the outside when the light beams are introduced to the radiating surface through reflection from the reflecting surfaces and directly through the bottom, so that the light beams are radiated to the outside in a predetermined beam angle.
