Abstract

A photoluminescence wavelength conversion component comprises a first portion having at least one photoluminescence material; and a second portion comprising light reflective material, wherein the first portion is integrated with the second portion to form the photoluminescence wavelength conversion component.

Claims

1. A photoluminescence wavelength conversion component comprising:

a first portion having at least one photoluminescence material; and

a second portion comprising light reflective material, wherein the first portion and the second portion form a unitary component that is integrally manufactured and are not separate components assembled together, wherein the unitary component forms the photoluminescence wavelength conversion component, and

wherein the photoluminescence wavelength conversion component having the first portion and the second portion is extended in a lengthwise direction and has a constant cross-sectional profile along the lengthwise direction.

2. The component of claim 1, and further comprising a third optical portion, wherein the third optical portion is integrated with the first and second portions to form the photoluminescence wavelength conversion component.

3. The component of claim 2, wherein the third optical portion comprises a lens.

4. The component of claim 2, wherein the third optical portion comprises a light diffusive material.

5. The component of claim 1, wherein the first portion and the second portion have matching indices of refraction.

6. The component of claim 1, wherein the first portion and the second portion are manufactured from the same base material.

7. The component of claim 1, wherein the first portion and the second portion are co-extruded.

8. The component of claim 1, wherein the at least one photoluminescence material is incorporated in and homogeneously distributed throughout the volume of the first portion.

9. The component of claim 1, wherein the second portion comprises an angled slope extending from the base of the first portion.

10. The component of claim 9, wherein the angled slope extends from the base of the first portion to a top of an attachment portion of the photoluminescence wavelength conversion component.

15. The component of claim 1, wherein the component is linear.

16. The component of claim 1, wherein the light reflective material is incorporated in and substantially homogeneously distributed throughout the volume of the second portion.

17. The component of claim 1, wherein the second portion extends from a base of the first portion.

18. The component of claim 1, wherein a light reflective surface of the second region is within the interior of the photoluminescence wavelength conversion component.

19. The component of claim 17, wherein the second region comprises an attachment portion.

20. The component of claim 17, wherein the second portion extends outwardly from a base of the first portion.

11. A method of manufacturing a lamp, comprising:

receiving an integrated photoluminescence wavelength conversion component, wherein the integrated photoluminescence wavelength conversion component comprises a first portion having at least one photoluminescence material and a second portion comprising light reflective material, wherein the first portion and the second portion form a unitary component that is integrally manufactured and are not separate components assembled together, wherein the integrated photoluminescence wavelength conversion component having the first portion and the second portion is extended in a lengthwise direction and has a constant cross-sectional profile along the lengthwise direction; and

assembling the lamp by attaching the integrated photoluminescence wavelength conversion component to a base, such that the integrated photoluminescence wavelength conversion component is attached to the base without separately attaching the first portion and the second portion to the base.

12. A method of manufacturing a photoluminescence wavelength conversion component, comprising:

co-extruding a first portion having at least one photoluminescence material; and

co-extruding a second portion comprising light reflective material, wherein the first portion and the second portion form a unitary component that is integrally manufactured and are not separate components assembled together, wherein the photoluminescence wavelength conversion component having the first portion and the second portion is extended in a lengthwise direction and has a constant cross-sectional profile along the lengthwise direction.

13. The method of claim 12 and further comprising:

co-extruding a third optical portion.

14. The method of claim 13, wherein the third optical portion comprises a light diffusive material.
