Abstract
A light-emitting diode includes a substrate having a main surface, a light-emitting diode device arranged on the main surface, a translucent sealing resin portion sealing the light-emitting diode device so that the light-emitting diode device is implemented as an independent convex portion projecting from the main surface, and a reflector arranged on the main surface so as to surround an outer perimeter of the sealing resin portion with an inclined surface at a distance from the outer perimeter.
Claims13
A light-emitting diode comprising:
- a substrate having a main surface;
- a light-emitting diode device arranged on said main surface;
- a translucent sealing resin portion sealing said light-emitting diode device so that said light-emitting diode device is implemented as an independent convex portion projecting from said main surface;
- and
- a reflector arranged on said main surface so as to surround an outer perimeter of said sealing resin portion with an inclined surface at a distance from the outer perimeter so that a recessed portion is defined in the reflector and the light-emitting diode is disposed in the recessed portion,
- wherein the translucent sealing resin portion fills the recessed portion only partially so as to leave at least part of the inclined surface of the reflector exposed, and
- said inclined surface comprises three portions of different angles of inclination from each other.

A light-emitting diode comprising:
- a substrate comprising a main surface;
- a light-emitting diode device arranged on the main surface;
- a translucent sealing resin portion sealing the light-emitting diode device so that the light-emitting diode device and the translucent sealing resin portion form a convex portion projecting from the main surface;
- and
- a reflector arranged on the main surface so as to surround an outer perimeter of the sealing resin portion with an inclined surface at a distance from the outer perimeter,
- wherein the reflector comprises a first upper surface and a second upper surface that are parallel to the main surface, the inclined surface inclines from the first upper surface, and the second upper surface steps down from the first upper surface and is disposed outside the first upper surface.
