Abstract

One embodiment of a method for configuring consumption of service includes identifying a service to be consumed by a user, identifying a plurality of bearer technologies across which at least one electronic device can access the service, selecting one of the plurality of bearer technologies for use in configuring the at least one electronic device, and configuring the at least one electronic device for the service using one of a plurality of management frameworks according to the selected bearer technology.

Claims

1. An illumination assembly comprising:

a light source;

a reflector cup, said light source being located within said reflector cup, said reflector cup having a reflective surface with at least one diffuser;

a clear encapsulant at least partially filling said reflector cup;

said at least one diffuser comprising a plurality of distensions formed on a wall of said reflector cup; and

wherein said plurality of distensions comprises an array of dimples.

3. The illumination assembly of claim 1, said at least one diffuser comprising a surface coating on a wall of said reflector cup.

6. The illumination assembly of claim 1, wherein said plurality of distensions is arranged as a spatially uniform array.

7. The illumination assembly of claim 1, wherein said plurality of distensions has an irregular spatial arrangement.

8. The illumination assembly of claim 1, wherein said plurality of distensions comprises an array of heterogeneous shapes.

9. The illumination assembly of claim 1, wherein said plurality of distensions comprises a mix of different shapes.

10. The illumination assembly of claim 1, wherein said plurality of distensions comprises a continuously varying profile on said wall of said reflector cup.

11. The illumination assembly of claim 1, said at least one diffuser comprising a plurality of varied slopes to which said encapsulant clings to prevent delamination of the encapsulant from said reflector cup.

12. The illumination assembly of claim 1, further comprising a lens mounted over said reflector cup and said light source, said encapsulant at least partially filling a void under said lens.

13. The illumination assembly of claim 1, further comprising a housing around said reflector cup and said light source.

14. The illumination assembly of claim 1, further comprising a plurality of electrically conductive leads.
