Abstract

Multipurpose lighting systems and methods of providing controllable lighting are provided. A lighting system includes a sheet of flexible material, a plurality of light sources and a controller. The plurality of light sources are attached to the sheet of flexible material and configured to emit diffused light. The controller is coupled to the plurality of light sources and is configured to control one or more of the plurality of light sources according to one of a plurality of prescribed lighting characteristics associated with a respective plurality of different lighting tasks. In some examples, the lighting system includes a camera coupled to the sheet of flexible material configured to capture at least one image of an object synchronously with the light emitted by the plurality of light sources.

First claim

What is claimed:

1. A lighting system comprising:
a sheet of flexible material;
a plurality of light sources attached to the sheet of flexible material;
a transparent cover disposed over the sheet of flexible material;
a transparent cushioning material positioned between the plurality of light sources and the transparent cover;
a diffusion material positioned between the plurality of light sources and the transparent
cover such that the lighting system is configured to emit diffused light;
a controller coupled to the plurality of light sources, the controller configured to control one or more of the plurality of light sources according to one of a plurality of prescribed lighting characteristics associated with a respective plurality of different lighting tasks; and
a camera coupled to the sheet of flexible material in a vicinity of the plurality of light sources, the camera configured to capture one or more images of an object positioned within an incubator synchronously with the light emitted by the one or more of the plurality of light sources;
wherein the sheet of flexible material is configured to be removably disposed on the incubator such that the emitted diffused light is transmitted into the incubator.

2. The lighting system of claim 1 , wherein each prescribed lighting characteristic includes at least one of a predetermined intensity, a predetermined spectrum, a predetermined distribution, a predetermined duration or a predetermined timing.

3. The lighting system of claim 1 , wherein the plurality of different lighting tasks includes at least one of circadian entrainment, illumination for remote viewing of the object, shadow-free illumination for local viewing of the object, chromatically-enhanced illumination for examination of the object, or illumination for a medical procedure.

4. The lighting system of claim 1 , wherein the camera is configured to capture one or more images within at least one of a visible light spectrum or an infrared (IR) light spectrum.

5. The lighting system of claim 1 , further comprising a display device coupled to the camera via a wired connection or a wireless connection.

6. The lighting system of claim 1 , further comprising a user interface coupled to the controller, the user interface configured to receive a selection for the one of the plurality of prescribed lighting characteristics.

7. The lighting system of claim 1 , wherein the sheet of flexible material includes a first side and a second side opposite the first side, the plurality of light sources being attached to the first side, the second side or a combination thereof.

8. The lighting system of claim 1 , wherein the plurality of light sources includes at least two subsets of light sources, the at least two subsets of light sources configured to emit the light with at least one of different spectral characteristics or different intensities.

9. The lighting system of claim 8 , wherein the controller is configured to control at least one of selection of a number of light sources among the plurality of light sources, selection of one or more subsets of light sources among the at least two subsets of light sources, an amount of power distributed among the plurality of light sources, an onset of the emitted light or a duration of the emitted light.

10. The lighting system of claim 1 , wherein the transparent cover is formed of a skid resistant material.

11. A method of providing controllable lighting, the method comprising the steps of:
positioning an illuminance blanket over a top surface of an incubator and emitting diffused light into the incubator from above;
receiving, by a controller, an indication of a lighting task to be performed via the illuminance blanket, the illuminance blanket including a plurality of light sources attached to a sheet of flexible material, a transparent cover disposed over the sheet of flexible material, a transparent cushioning material positioned between the plurality of light sources and the
transparent cover, and a diffusion material positioned between the plurality of light sources and
the transparent cover such that the illuminance blanket is configured to emit diffused light;
identifying, by the controller, a prescribed lighting characteristic associated with the indicated lighting task from among a plurality of prescribed lighting characteristics associated with a respective plurality of different lighting tasks; and
controlling one or more of the plurality of light sources of the illuminance blanket to emit diffused light according to the identified prescribed lighting characteristic; and
capturing, via a camera coupled to the sheet of flexible material in a vicinity of the plurality of light sources, one or more images of an object positioned within the incubator synchronously with the light emitted by the one or more of the plurality of light sources.

12. The method of claim 11 , wherein each prescribed lighting characteristic includes at least one of a predetermined intensity, a predetermined spectrum, a predetermined distribution, a predetermined duration or a predetermined timing.

13. The method of claim 11 , wherein the controlling of the one or more of the plurality of light sources includes controlling at least one of selection of a number of light sources among the plurality of light sources, an amount of power distributed among the plurality of light sources, an onset of the emitted light or a duration of the emitted light.

14. The method of claim 11 , further comprising capturing, via a microphone, audio information received from the object.

15. The method of claim 14 , further comprising storing, in non-transitory storage, at least one of the audio information or the one or more images.

16. The method of claim 11 , further comprising storing, in non-transitory storage, at least one of a verification that the identified prescribed lighting characteristic lighting has been emitted or a timestamp indicating when the identified prescribed lighting characteristic was emitted.

17. The method of claim 11 , wherein the plurality of different lighting tasks includes at least one of circadian entrainment of the infant, illumination for remote viewing of the infant, shadow-free illumination for local examination of the infant, illumination for a medical procedure, and chromatically-enhanced illumination for at least one of cyanosis observation or vein enhancement.

18. The method of claim 17 , wherein the controlling of the one or more of the plurality of light sources includes controlling a timing, a duration and an intensity of the emitted diffused light to promote the circadian entrainment of the infant.

19. The method of claim 17 , wherein the plurality of different lighting tasks includes at least one of illumination for remote viewing of the infant, shadow-free illumination for local examination of the infant, and illumination for a medical procedure, wherein the illumination for the medical procedure has a higher intensity than the shadow-free illumination for the local examination of the infant and the illumination for the remote viewing of the infant.

20. An illuminance blanket comprising:
a flexible cover having a top layer and a bottom layer joined together at peripheral edges thereof and at a plurality of joints to form a plurality of internal compartments, each of the plurality of joints extending transverse to either a length or a width of the flexible cover;
a plurality of light sources configured to emit diffused light integrated within the flexible cover, at
