Abstract

A light emitting device includes: a frame having an opening; at least one light emitting diode (LED) disposed on the frame; a reflector disposed on the frame; and a reflective protrusion projecting from the reflector, wherein light emitted from at least one light emitting diode is reflected by the reflector through the opening, wherein the vertical axis of the reflective protrusion is perpendicular to a plane formed by extending the upper surface of the frame, wherein the upper surface of the frame contacts the reflector, and wherein a distance between two LEDs with one LED placed therebetween is greater than a distance between one LED and the reflector. Because a light source is disposed on the frame of the light emitting device, it is possible to easily exchange the light source of the light emitting diode by removing and attaching the frame without disassembling the entire lighting device.
