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 replaceable component for a luminaire, the luminaire having an organic emissive component comprising an OLED, and an outcoupling component configured to outcouple light from the organic emissive component, said replaceable component comprising:
a self-contained index matching component comprising a packet of an index matching material;
wherein the replaceable component is replaceable separately from at least one other component of the luminaire;
wherein, the outcoupling component provides a magnification of the OLED such that, when viewed from a distance of 3 m or less, the OLED appears to fill the outcoupling component.

2. The replaceable component for a luminaire of claim 1 , said replaceable component further comprising an OLED, wherein said replaceable component is configured to connect optically to the outcoupling component.

3. The replaceable component of claim 2 , wherein the self-contained index matching component provides an optical connection between the replaceable component and the outcoupling component.

4. An organic emissive component configured to connect to a luminaire device having an ellipsoidal outcoupling component, said organic emissive component comprising an OLED;
wherein the emissive area of the OLED is 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 device; and
wherein the outcoupling component provides a magnification of the OLED at least such that, when viewed from a distance of 3 m or less, the OLED appears to fill the outcoupling component.

5. The organic emissive component of claim 4 , wherein the outcoupling component has an index of refraction of 1.4-2.0.

6. The organic emissive component of claim 4 , wherein the emissive area of the OLED is about 60-75% 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 device.

7. The organic emissive component of claim 4 , further comprising an index matching component disposed above the OLED, wherein the index matching component is disposed between the OLED and the outcoupling component when the organic emissive component is connected to the luminaire device.

8. The organic emissive component of claim 7 , wherein the index matching component has an index of refraction of 1.4-2.0.

9. A luminaire comprising:
an ellipsoidal outcoupling component having a base cross-section area A; and
an OLED having an emissive area in the range of 0.6 A-0.9 A, the emissive area of the OLED having an outline shape substantially equivalent to the cross-sectional shape of the ellipsoidal outcoupling component;
wherein the outcoupling component provides a magnification of the OLED at least such that, when viewed from a distance of 3 m or less, the OLED appears to fill the outcoupling component.

10. The luminaire of claim 9 , wherein the OLED has an emissive area of not more than about 0.75 A.

11. The luminaire of claim 9 , further comprising:
an index matching component disposed between the OLED and the outcoupling component.

12. The luminaire of claim 11 , wherein the index matching component is replaceable separately from the outcoupling component.

13. The luminaire of claim 9 , wherein the OLED is replaceable separately from the outcoupling component.

14. The luminaire of claim 9 , wherein the outcoupling component has a refractive index not less than the refractive index of the OLED emissive surface material.

15. The luminaire of claim 9 , wherein light provided by the luminaire comprises light having a first color viewed at a first angle from the luminaire and light having a second color, different from the first color, viewed at a second angle from the luminaire.
