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.
Claims20
A light emitting device comprising:
- a frame having an opening;
- at least one light emitting diode (LED) disposed on the frame;
- a reflector which reflects light irradiated from the light emitting diode;
- and
- a reflective protrusion projecting from the reflector towards the opening,
- wherein a vertex of the reflective protrusion is closer to the opening than a point where a vertical axis of the reflective protrusion would meet light from at least one LED emitted to the reflective protrusion at a minimum angle with relation to an upper surface of the frame,
- 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, and
- wherein the upper surface of the frame contacts the reflector.
A light emitting device comprising:
- a frame formed with an opening there through;
- a heat radiator formed on an outer portion of the frame;
- at least one light emitting diode (LED) disposed on the frame;
- a reflector configured to reflect light irradiated from the at least one light emitting diode;
- and
- a reflective protrusion projecting from the reflector towards the opening,
- wherein a vertex of the reflective protrusion is closer to the opening than a point where a vertical axis of the reflective protrusion would meet light from at least one LED emitted to the reflective protrusion at a minimum angle with relation to an upper surface of the frame, and
- wherein the light emitted from the 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, and
- wherein the upper surface of the frame contacts the reflector.
A light emitting device comprising:
- a circular frame having an opening there through;
- a plurality of light emitting diodes positioned around the circular frame;
- a dome-shaped reflector comprising an inner reflective surface, the dome-shaped reflector covering the plurality of light emitting diodes and reflecting light emitted from the plurality of light emitting diodes;
- and
- a reflective protrusion projecting from the inner reflective surface of the dome-shaped reflector towards the opening,
- wherein a vertex of the reflective protrusion is closer to the opening than a point where a vertical axis of the reflective protrusion would meet light from at least one LED emitted to the reflective protrusion at a minimum angle with relation to an upper surface of the frame,
- wherein the vertical axis of the reflective protrusion is perpendicular to a plane formed by extending the upper surface of the frame, and
- wherein the upper surface of the frame contacts the reflector.
