The present invention relates to a hybrid-type lens having a top emitting type and a side emitting type mixed, the LED lens comprising a micro-optical pattern. The LED lens, according to the present invention, is a lens for diffusing and scattering light emitting from an LED, and comprises: an upper structure which has an outer side surface, the outer side surface having an inclined truncated cone shape, or the outer side surface having an uninclined cylindrical shape; an intermediate structure which has a spherical band shape, is connected to the lower part of the upper structure, and has an outer surface having a convex curved-surface shape; and a lower structure which has a cylindrical shape, is connected to the lower part of the intermediate structure, and has an outer side surface, wherein a funnel-shaped groove is formed on the top surface of the upper structure so that a reflective surface of the upper structure is formed on the top surface of the upper structure, and a micro-optical pattern is formed on the convex curved-surface shaped outer surface of the intermediate structure, and a cavity that can accommodate an LED is formed on the bottom surface of the lower structure. |
