    Abstract: A light emitting diode (LED) lens comprises a light incident surface on a bottom surface of the LED lens facing a light source. A light exit surface, having a size greater than the bottom surface, is defined by a top surface of the LED lens. A planar portion, emitting light incident through the light incident surface, is in a central region of the light exit surface. At least one protrusion portion, protruding to be stepped with respect to the planar portion, is in a region of the light exit surface except for the central region. A reflective surface, defined by lateral surfaces of the LED lens between the top surface of the LED lens and the bottom surface thereof, guides the light incident through the light incident surface, and contacts a lower portion of the light exit surface corresponding to a boundary between the protrusion and the planar portions.

    Abstract: A are provided a light source module. The light source module including a light emitting device configured to emit light in a light emitting direction; and an optical device including a first surface disposed over the light emitting device and having a groove recessed in the light emitting direction in a central portion through which an optical axis of the optical device passes, and a second surface disposed opposite to the first surface and configured to refract light incident through the groove to be emitted to the outside. The optical device includes a plurality of ridges disposed on the second surface and periodically arranged in a direction from the optical axis to an edge of the optical device connected to the first surface.

    Abstract: An LED lens includes a recess disposed in a quadrangular bottom surface of the LED lens and configured to have a light source disposed therein, wherein an internal surface of the recess, including lateral surfaces and top surfaces, is a light incident surface. The LED lens further includes a top surface forming a light exit surface, having a size greater than that of the bottom surface, and having a quadrangular shape; and lateral surfaces of the LED lens, disposed between the top and bottom surfaces of the LED lens, forming a reflective surface, and guiding light incident to the LED lens through the light incident surface to the light exit surface. The top surfaces of the light incident surface form an inverted quadrangular pyramid.
