Complex primary optics with intermediate elements
View Patent ↗A light emitter package comprising a light emitter disposed on a surface and a primary optic comprising an encapsulant disposed over the light emitter is disclosed. The package further comprises at least one intermediate element on the surface and at least partially surrounding the light emitter such that the intermediate element at least partially defines the shape of the primary optic. The intermediate element is configured so at least a portion of the intermediate element can be removed.
1. A light emitter package, comprising:
a light emitter disposed on a surface;
at least one intermediate element on said surface at least partially surrounding said light emitter, each of said intermediate elements configured such that at least a portion of said intermediate element can be removed; and
an encapsulant over said light emitter forming a primary optic, said at least one intermediate element at least partially defining the shape of said primary optic.
2. The light emitter package of claim 1 , wherein said primary optic is capable of beam shaping.
3. The light emitter package of claim 1 , wherein said light emitter comprises an LED.
4. The light emitter package of claim 1 , wherein said intermediate element includes a meniscus forming feature.
5. The light emitter package of claim 1 , wherein said primary optic comprises an exit face and has a tapered shape such that at least a portion closer to the base of said primary optic is narrower than at least a portion of the exit face.
6. The light emitter package of claim 1 , wherein said primary optic comprises an overhang portion.
7. The light emitter package of claim 1 , wherein said primary optic comprises an asymmetrical shape.
8. The light emitter package of claim 1 , wherein said primary optic includes wavelength conversion material.
9. The light emitter package of claim 1 , further comprising a wavelength conversion material over said primary optic.
10. The light emitter package of claim 1 , wherein said intermediate element includes a wavelength conversion material.
11. The light emitter package of claim 1 , wherein said intermediate element is comprised of a material which is sacrificial.
12. The light emitter package of claim 11 wherein said material is selected from the group consisting of thermoplastic polymers, polyvinyl alcohol, wax, and soluble plastics.
13. The light emitter package of claim 1 , wherein said intermediate element is permanent.
14. The light emitter package of claim 1 , further comprising a secondary optic over said primary optic.
15. The light emitter package of claim 1 , wherein said intermediate element further comprises an air gap within said intermediate element.
16. The light emitter package of claim 1 , wherein at least a portion of said intermediate element is reflective.
17. An array of light emitter packages, comprising:
a plurality of light emitters disposed on a surface;
at least one intermediate element on said surface at least partially surrounding said light emitters, each of said intermediate elements configured such that at least a portion of said intermediate element can be removed; and
an encapsulant over each of said light emitters forming primary optics, said at least one intermediate element at least partially defining the shape of said primary optics.
18. The array of light emitter packages of claim 17 , wherein at least some of said plurality of light emitters comprise LEDs.
19. The array of light emitter packages of claim 17 , wherein said intermediate element includes a plurality of meniscus forming features.
20. The array of light emitter packages of claim 17 , wherein said primary optics have an exit face and have a tapered shape such that at least a portion closer to the base of said primary optics is narrower than at least a portion closer to the exit face.
21. The array of light emitter packages of claim 17 wherein said primary optics comprise an overhang portion.
22. The array of light emitter packages of claim 17 , wherein said primary optics comprise an asymmetrical shape.
23. The array of light emitter packages of claim 17 , further comprising a wavelength conversion material.
24. The array of light emitter packages of claim 17 , wherein said intermediate element is comprised of a material which is sacrificial.
25. The array of light emitter packages of claim 17 , wherein said intermediate element is permanent.
26. The array of light emitter packages of claim 17 , wherein said intermediate element further comprises an air gap within said intermediate element.
27. The array of light emitter packages of claim 17 , wherein at least a portion of said intermediate element is reflective.
