Abstract
Abstract There is disclosed a light emitting device which includes a header and an angle stripe light emitting diode. The header has a longitudinal axis and a forward mounting surface. The forward mounting surface includes a leading edge portion which extends perpendicular to the longitudinal axis. The mounting surface further includes a trailing alignment edge portion which extends rearwardly from the leading edge portion at a predetermined compensating angle. The light emitting diode is affixed in electrical and heat transfer relation to the mounting surface of the header such that the emitting facet is aligned with the trailing alignment edge portion of the header. The trailing alignment edge portion compensates for the offset angle that light is emitted from a stripe light emitting diode.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A light emitting device comprising: a header having a longitudinal axis and a forward mounting surface, said mounting surface having a leading edge portion extending perpendicular to the longitudinal axis and a trailing alignment edge portion extending rearwardly from the leading edge portion at a predetermined compensating angle; and, a light emitting element including a light emitting facet, said light emitting element being secured in electrical and heat transfer relation to said mounting surface with the emitting facet aligned with the trailing alignment edge portion whereby light is emitted from the facet substantially along the longitudinal axis of the header.
Claim 2
Dependent Claim
100 words
A light emitting device comprising: a header having a longitudinal axis and a forward mounting surface, said mounting surface having a leading edge portion extending perpendicular to the longitudinal axis and a trailing alignment edge portion extending rearwardly from the leading edge portion at a predetermined compensating angle; and, a light emitting element including a light emitting facet, said light emitting element being secured in electrical and heat transfer relation to said mounting surface with the emitting facet aligned with the trailing alignment edge portion whereby light is emitted from the facet substantially along the longitudinal axis of the header.
Claim 3
Dependent Claim
21 words
A light emitting device as claimed in claim 1 wherein said trailing alignment edge portion intersects with the leading edge portion.
Claim 4
Dependent Claim
19 words
A light emitting device as claimed in claim 1 wherein said predetermined angle is between about 5° and 20°.
Claim 5
Dependent Claim
15 words
A light emitting device as claimed in claim 1 wherein said predetermined angle is 5°.
Claim 6
Dependent Claim
15 words
A light emitting device as claimed in claim 1 wherein said predetermined angled is 15°.
Claim 7
Dependent Claim
34 words
A light emitting device as claimed in claim 1 wherein said light emitting element one of an angled stripe light emitting diode, super radiant light emitting diode, or a super luminescent light emitting diode.
Claim 8
Dependent Claim
29 words
A light emitting diode as claimed in claim 1 wherein the trailing edge portion is cut into the mounting surface and extends across a portion of the mounting surface.
Claim 9
Dependent Claim
27 words
A light emitting diode as claimed in claim 7 wherein the trailing edge portion extends rearwardly from the leading edge portion in proximity to the longitudinal axis.
Claim 10
Dependent Claim
42 words
A light emitting diode as claimed in claim 8 wherein a corner of the light emitting device is positioned where the trailing alignment edge portion meets the leading edge portion so as to position the facet in line with the longitudinal axis.
