Abstract

Luminaires and luminaire components are provided that may include emissive, index-matching, and/or outcoupling components that are replaceable separately from other components of the luminaire. In some embodiments, an index-matching component may include a gel sheet or pad that can be disposed between an emissive component and an outcoupling component. The index-matching component may be replaceable separately from the emissive and outcoupling components. In some embodiments, an emissive component including an OLED panel and/or an index-matching component may be replaceable separately from other components of the luminaire.

First claim

The invention claimed is:

1. A device comprising:
an emissive package configured to connect to a luminaire body to form a luminaire, said package comprising:
an organic emissive component having a first side configured to connect to the luminaire body and a second side; and
a self-contained index matching component disposed at least partially above the second side of the organic emissive component, the index matching component comprising a packet of index matching material;

wherein at least a portion of the emissive package is replaceable separately from an outcoupling component of the luminaire; and
wherein, when the emissive package is connected to the luminaire body, the index matching component is in direct physical contact with a surface of the outcoupling component and with the second side of the organic emissive component, such that there is no air gap between the organic emissive component and the outcoupling component.

2. The device of claim 1 , wherein the organic emissive component is replaceable separately from the outcoupling component.

3. The device of claim 1 , wherein the index matching component is replaceable separately from the outcoupling component.

4. The device of claim 1 , wherein the index matching component is replaceable separately from the organic emissive component.

5. The device of claim 1 , wherein the index-matching component comprises a gel pad.

6. The device of claim 1 , wherein the index-matching component comprises a disposable gel packet.

7. The device of claim 1 , wherein the index matching component comprises a gel sheet.

8. The device of claim 1 , wherein the index-matching component comprises an encapsulated gel.

9. The device of claim 1 , wherein the index-matching component has a refractive index of 1.4-2.0.

10. The replaceable component of claim 1 , wherein the index matching material has an index of refraction within 90% of an index of refraction of the outcoupling component.

11. The device of claim 1 , wherein the index matching material has an index of refraction within 90% of an index of refraction of an emissive surface material of the emissive component.

12. The device of claim 1 , wherein the outcoupling component comprises a bulb having a shape selected from the group consisting of: a dome, pyramid, a parallelpiped, and a hemisphere.

13. The device of claim 12 , wherein the emissive area of the organic emissive component has an outline shape substantially equivalent to a cross-section of the outcoupling component in a plane parallel to the organic emissive component.

14. The device of claim 1 , wherein the emissive area of the organic emissive component has an outline shape substantially equivalent to a cross-section of the outcoupling component in a plane parallel to the organic emissive component.

15. The device of claim 1 , wherein the index matching component comprises a transparent material having a Young's modulus of 0.1 MPa to 1 GPa.

16. The device of claim 1 , wherein the organic emissive component comprises an OLED having an emissive area of about 60-90% of the area of the largest cross-section of the outcoupling component in a plane parallel with the OLED when the OLED is connected to the luminaire body.

17. The device of claim 16 , wherein the organic emissive component comprises an OLED having an emissive area of about 60-75% of the area of the largest cross-section of the outcoupling component in a plane parallel with the OLED when the OLED is connected to the luminaire body.

18. The device of claim 1 , wherein light provided by the luminaire comprises light having a first color viewable at a first angle from the luminaire and light having a second color, different from the first color, viewable at a second angle from the luminaire.

19. The device of claim 1 , further comprising the outcoupling component, wherein the outcoupling component is disposed to outcouple light generated by the organic emissive component from the organic emissive component into an ambient region around the luminaire.
