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 light emitting module is provided including a light emitting device and a reflective member disposed on the light emitting device. The reflective member includes a hole with an inner wall thereof provided as a reflective surface, having a lower aperture having a quadrangular shape and an upper aperture having a shape geometrically different from that of the lower aperture. The inner wall includes first to fourth inclined surfaces extending from respective sides of the lower aperture to the upper aperture, and first to fourth connection surfaces extending from a respective vertex of the lower aperture to the upper aperture to connect the inclined surfaces to each other. The illuminance distribution of emitted light has a quadrangular shape. Accordingly, a relatively high degree of design freedom may be secured for a reflective member while maintaining required illuminance distribution characteristics.

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.
