Abstract
A light emitting device includes a first lead frame having a top surface including a first region and a second region, a first metal layer disposed on the first region of the top surface, a reflector layer in contact with the second region of the top surface, a light emitting element mounted on the first metal layer and electrically connected to the first lead frame, and a transparent resin layer covering the light emitting element and in contact with the first metal layer.
Claims17
A light emitting device comprising:
- a first lead frame having a top surface including a first region and a second region;
- a first metal layer disposed on the first region of the top surface;
- a reflector layer in contact with the second region of the top surface;
- a light emitting element mounted on the first metal layer and electrically connected to the first lead frame;
- and
- a transparent resin layer covering the light emitting element and in contact with the first metal layer.
A light emitting device comprising:
- a first lead frame;
- a second lead frame disposed adjacent to the first lead frame with a space therebetween;
- a light emitting element disposed on and electrically connected to the first lead frame;
- a reflector layer that is made of resin, disposed directly on parts of the first and second lead frames;
- a transparent resin layer covering the light emitting element and surrounded by the reflector layer;
- and
- a phosphor layer disposed on an upper surface of the reflector layer.
A method for manufacturing a light emitting device, comprising:
- forming a reflector layer having an opening, on a plate;
- forming a phosphor layer on an upper surface of the reflector layer, so as to cover the opening;
- removing the plate and attaching, to a lower surface of the reflector layer, a first lead frame on which a light emitting element is mounted and a second lead frame located adjacent to the first lead frame with a space therebetween, such that the light emitting element is located within the opening;
- and
- disposing a transparent resin in the opening between the first lead frame and the second lead frame.
