PURPOSE: An asymmetric LED(Light Emitting Diode) lens for unilateral light projection and an LED lamp using the same are provided to prevent dazzling phenomenon by emitting light in the lateral direction through an external plane and a projection plane. CONSTITUTION: A body unit(130) has an LED device in a recessive groove(112), and first and second reflective planes(140a,140b) are formed at an inclination angle in relation to an optical shaft direction at the front plane of the body unit. A projection plane(150) is perpendicular to the optical shaft direction between the first and second reflection planes. An external plane(160) encloses the first and second reflection planes. |
