Abstract

Embodiments of claimed subject matter are directed to an illuminating surgical device comprising an array of illuminating elements and an array of louvers to direct light from the individual illuminating elements toward a surgical field.

Claims (40)

1. A method of constructing an illuminating surgical device, comprising:

arranging an array of illuminating elements over a substrate; and

forming an array of reflective devices to direct light from individual illuminating elements of the array of illuminating elements toward a target surgical field, individual reflectors of the array of reflective devices being oriented at an angle that reduces backscatter and increases illumination at the target surgical field.

2. The method of claim 1 , further comprising:

forming an array of angled reflective surfaces in correspondence with the array of illuminating elements and the array of reflective devices to direct the light from the individual illuminating elements towards the individual reflectors of the array of reflective devices.

3. The method of claim 2 , wherein the array of reflective devices comprises a

reflective side and wherein the method further comprises:

coating a side opposite the reflective side of the array of reflective devices with a substantially light-absorbing material.

4. The method of claim 3 , further comprising:

forming an array of louvers, individual louvers of the array of louvers having a reflective

side to direct light from the individual illuminating elements of the array of illuminating elements toward a target surgical field.

5. A method of forming an illuminating surgical device, the method comprising:

disposing an array of illuminating elements on a substrate;

disposing an array of slanted reflectors, individual reflectors of the array of slanted reflectors being in correspondence with, and slanted in the direction of, individual illuminating elements of the array of illuminating elements, the slanted individual reflectors being mounted substantially coplanar with the individual illuminating elements; and

forming an array of louvers, individual louvers of the array of louvers having a reflective side to direct light from the individual illuminating elements of the array of illuminating elements toward a target surgical field, the individual louvers of the array of louvers being oriented at an angle that reduces backscatter and increases illumination at the target surgical field.

6. The method of claim 5 , wherein the individual louvers of the array of louvers,

are adjustable between angles of about 100 degrees to about 160 degrees relative to a substantially planar layer of the array of illuminating elements.

7. The method of claim 5 , further comprising:

coating a top side of the individual louvers of the array of louvers with a substantially non-reflective coating.

8. The method of claim 5 , further comprising:

anharmonically spacing at least some illuminating elements of the array of illuminating elements relative to other illuminating elements of the array of illuminating elements.

9. The method of claim 5 , wherein beamwidths of at least some illuminating elements of the array of illuminating elements overlap with beamwidths of at least some other illuminating elements of the array of illuminating elements.

10. The method of claim 5 , wherein disposing the array of slanted reflectors in the direction of the individual illuminating elements further comprises:

orienting the slanted individual reflectors to an angle that directs the light from the illuminating elements of the array of illuminating elements towards corresponding louvers of the array of louvers.

11. The method of claim 10 , wherein orienting the slanted individual reflector comprises:

positioning the slanted individual reflectors at an angle of between about 25 degrees to about 55 degrees relative to a substantially planar surface of the array of illuminating elements.

12. The method of claim 5 , wherein illuminating elements of the array of illuminating elements utilize light emitting diodes having a color temperature of between about 6500 degrees Kelvin to about 7500 degrees Kelvin.

13. The method of claim 5 , wherein one or more reflectors of the array of reflective devices comprises a Fresnel-type lens at a side of the one or more reflectors.

14. A method of forming an illuminating surgical device, comprising:

forming a substrate layer to accommodate an array of illuminating elements;

forming a spacing layer over the substrate layer to accommodate the array of

illuminating elements and to accommodate an array of slanted reflectors, individual slanted reflectors of the array of slanted reflectors being mounted substantially coplanar, and in correspondence with, individual illuminating elements of the array of illuminating elements; and

forming a louver layer comprising an array of louvers, each louver having a reflective underside, to direct light from individual slanted reflectors of the array of slanted reflectors toward a target surgical field, the louver layer to direct the light from the individual reflectors in a manner that reduces backscatter and increases illumination at the target surgical field.

15. The method of claim 14 , wherein one or more louvers of the array of louvers are adjustable between angles of about 100 degrees to 160 degrees relative to a substantially planar surface of the array of illuminating elements.

16. The method of claim 14 , further comprising:

coating a top side of one or more louvers of the array of louvers with a substantially light absorbing coating to reduce the backscatter.

17. The method of claim 14 , wherein beamwidths of at least some illuminating elements of the array of illuminating elements are situated so as to overlap with one another.

18. The method of claim 14 , wherein the array of slanted individual reflectors is formed to direct the light from the individual illuminating elements towards a corresponding louver of the array of louvers.

19. The method of claim 14 , wherein at least some of the individual slanted reflectors of the array of slanted reflectors are oriented at an angle approximately in the range of about 25 degrees to about 55 degrees relative to a substantially planar surface of the array of illuminating elements.

20. The method of claim 14 , wherein illuminating elements of the array of illuminating elements utilize light emitting diodes having a color temperature of between about 6500 degrees Kelvin and about 7500 degrees Kelvin.
