ASPHERICAL LENS FOR A LIGHT EMITTING DIODE AND LIGHT SOURCE ASSEMBLY INCLUDING THE SAME

摘要

PURPOSE: An aspherical lens for an LED and a light source assembly including the same are provided to reflect light output from a light source accommodated between a lens and a support member before entering a lens and hence, concentrate light in a desired part on the ground, thereby implementing a lamp with high luminance efficiency and luminance. CONSTITUTION: An aspherical lens(100) refracts light output from an LED. The LED is installed in a partial part of an arrangement plane(150). The aspherical lens includes an incident plane, an exit plane(110) and a single hump unit(130). The incident plane is defined by a shape of a groove accommodating the LED. The exit plane outputs light input from the incident plane. The single hump unit connects the exit plane and the bottom surface. [Reference numerals] (AA) Second direction; (BB) First direction
