Abstract
A light emitting device and method of fabricating the same is disclosed that comprises at least one light emitter comprising an active region which emits light. The device further comprising a submount arranged such that the at least one light emitter is mounted to the submount such that the active region is angled in relation to the submount.
Claims117
A light emitting device, comprising:
- at least one light emitter comprising an active region which emits light;
- and
- a submount arranged such that said at least one light emitter is mounted to said submount such that said active region is angled in relation to said submount, wherein a mounting surface of said light emitter is angled in relation to a plane of said active region.
A method for fabricating a LED chip, comprising:
- providing at least one LED on a substrate, said LED including first and second semiconductor layers;
- and
- mounting said at least one LED on a submount such that said submount is at an angle to said first and second semiconductor layers.
A LED package, comprising:
- a LED comprising a first semiconductor material, a second semiconductor material, a substrate, and an active region formed in between said first and second semiconductor materials;
- a submount, wherein said LED is mounted on said submount such that the mounting surface of said LED has a surface area equal to or smaller than any one of the remaining surfaces of said LED;
- and
- an encapsulant disposed over said LED.
