Patent abstract

Disclosed is a light emitting device. The light emitting device includes: a frame having an opening; at least one light emitting diode disposed on the frame; a reflector which reflects light irradiated from the light emitting diode and emits the light through the opening; and a reflective protrusion which is formed on an inner surface of the reflector and determines an orientation angle of the light emitted through the opening. Since a light source is disposed on the frame of the light emitting device according to the embodiment, 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.
