Abstract
A light emitting device module including a substrate including a plurality of light emitting areas, light emitting devices disposed in each light emitting area and to emit light, windows disposed on the substrate, each of the windows covering one of the light emitting areas and having an asymmetrical shape with respect to one direction, and a holder for coupling the windows, the holder including a plurality of openings each having an asymmetrical shape, in which each of the windows is individually disposed in a corresponding one of the openings and is detachably coupled to the holder.
Claims18
A light emitting device module comprising:
- a substrate comprising a plurality of light emitting areas;
- light emitting devices disposed in each light emitting area and to emit light;
- windows disposed on the substrate, each of the windows covering one of the light emitting areas and having an asymmetrical shape with respect to one direction;
- and
- a holder for coupling the windows, the holder including a plurality of openings each having an asymmetrical shape,
- wherein each of the windows is individually disposed in a corresponding one of the openings to be detachably coupled to the holder, and
- wherein each window includes a first insertion protrusion and a second insertion protrusion having different lengths from each other and disposed at opposite sides of the window to guide a coupling direction between the window and the holder, and the first insertion protrusion and the second insertion protrusion are asymmetrical with each other.
A window unit for a light emitting device module, comprising:
- one or more windows respectively covering light emitting areas and having an asymmetrical shape with respect to one direction, the window including a lens part having a curved surface and a flat part around the lens part;
- and
- a holder for coupling the windows, the holder including a plurality of openings each exposing the entire lens part of the corresponding window and having an asymmetrical shape,
- wherein:
- each of the windows is individually provided in a corresponding one of the openings and is detachably coupled to the holder;
- and
- the opening of the holder substantially exposes the entire flat part of the corresponding window.
A light emitting device module comprising:
- a substrate comprising a plurality of light emitting areas;
- light emitting devices disposed in each light emitting area to emit light in an upward direction;
- windows disposed on the substrate to cover each light emitting area;
- and
- a holder to couple the windows, the holder including openings that correspond to each of the light emitting areas,
- wherein:
- each of the windows is detachably coupled to the holder and individually provided in a corresponding opening among the openings along a direction to anisotropically control an advance direction of light;
- the holder includes a holder coupling protrusion protruding towards the window and a slot recessed from a surface of the holder;
- and
- each window includes window coupling protrusion protruding toward the holder to be engaged with the holder coupling protrusion.
A street light comprising:
- a pole extending in one direction;
- an arm connected to one side portion of the pole;
- and
- a light emitting device module disposed at one end portion of the arm, the light emitting device module comprising:
- a substrate comprising a plurality of light emitting areas;
- light emitting devices disposed in each light emitting area to emit light;
- windows disposed on the substrate, each of the windows covering each light emitting area and having an asymmetrical shape with respect to one direction;
- and
- a holder to couple the windows, the holder including a plurality of openings each having an asymmetrical shape,
- wherein each of the windows is individually disposed in a corresponding one of the openings and is detachably coupled to the holder, and each window includes a plurality of insertion members to guide a coupling direction between the window and the holder, and
- wherein the insertion members disposed at opposing sides of the window are asymmetrical with each other.
