Abstract

Systems and techniques for providing an auxiliary light source associated with an industrial application are presented. A luminescent label is attached to an optical assembly via a pressure sensitive adhesive. The luminescent label comprises at least a fluorophore layer configured to transform light received from a light source into output light that is projected the optical assembly.

Claims

1. A system, comprising:

an optical assembly that supports a lens; and

a luminescent label that is attached to an outer plane of the optical assembly via a pressure sensitive adhesive, and covers an aperture formed in the outer plane of the optical assembly, wherein the aperture formed in the outer plane receives light from a light source external from the optical assembly, and wherein the luminescent label comprises at least a fluorophore layer configured to transform the light received via the aperture formed in the outer plane into output light that is projected by the lens of the optical assembly.

2. The system of claim 1, wherein the fluorophore layer is printed onto a surface of a substrate of the luminescent label.

3. The system of claim 1, wherein the fluorophore layer of the luminescent label is applied to a clear substrate of the luminescent label.

4. The system of claim 2, wherein a mask layer associated with a mask pattern is further applied to the substrate of the luminescent label.

5. The system of claim 1, wherein a first layer of the luminescent label comprises the fluorophore layer and a second layer of the luminescent label comprises the pressure sensitive adhesive.

6. The system of claim 2, wherein the substrate is a rigid substrate.

7. The system of claim 1, wherein the luminescent label is attached to an optical shroud of the optical assembly via a mechanical technique.

8. The system of claim 1, wherein an adhesive layer of the luminescent label that comprises the pressure sensitive adhesive is attached to the optical assembly, and the adhesive layer covers the aperture of the optical assembly.

9. The system of claim 1, wherein at least the fluorophore layer is applied to a metal layer of the luminescent label.

10. The system of claim 1, wherein the light source is a light-emitting diode.

11. The system of claim 1, wherein the light source is a remote light source that transmits the light to the luminescent label via a light guide.

12. The system of claim 11, wherein the light guide further transmits the light to another luminescent label associated with an industrial indicator that comprises at least another fluorophore layer.

13. The system of claim 1, wherein the luminescent label comprises at least a first fluorophore layer configured to transform the light received from the light source into first output light and a second fluorophore layer configured to transform the light received from the light source into second output light.

14. The system of claim 1, wherein the luminescent label comprises at least one waveguide layer to guide the light received from the light source to the fluorophore layer.

15. An apparatus, comprising:

a fluorophore layer that comprises fluorophore to transform light, received from an external light source external to an optical assembly that supports a lens, into transformed light, wherein the transformed light is received by an aperture in an outer plane of the optical assembly, and wherein the transformed light is transmitted as output light for an industrial application via the lens of the optical assembly; and

a substrate layer attached to the fluorophore layer and a pressure sensitive adhesive layer, wherein a first surface of the substrate layer is attached to the fluorophore layer, and a second surface of the substrate is attached to the pressure sensitive adhesive layer.

16. The apparatus of claim 15, further comprising a mask layer applied to the substrate layer.

17. The apparatus of claim 15, further comprising a mask layer applied to the fluorophore layer.

18. The apparatus of claim 15, wherein the fluorophore layer is applied to a mask layer.

19. An apparatus, comprising:

a pressure sensitive adhesive (PSA) layer; and

a fluorophore layer applied to a surface of the PSA layer, wherein the fluorophore layer comprises fluorophore to transform light, received from a light source external from an optical assembly, into output light for an industrial application, wherein the fluorophore layer is distinct from the PSA layer, and wherein the PSA layer and the fluorophore layer cover an aperture in an outer plane of the optical assembly.

20. The apparatus of claim 19, further comprising a clear substrate attached to the PSA layer.
