22. A therapeutic light assembly for reducing infectious agent counts at a critical treatment site or open surgical site of a patient, comprising: a housing containing a therapeutic light source configured to be positioned proximate a critical treatment site or an open surgical site of a patient and emit light at the critical treatment site or open surgical site with the patient lying down, wherein the housing includes an inner panel curved about a housing axis and an outer panel concentric with the inner panel curved about the housing axis, wherein the therapeutic light source is held between the inner panel and the outer panel and configured to apply radially inward directed therapeutic light targeting the critical treatment site or the open surgical site; and a power source operatively connected to power the therapeutic light source.

23. The therapeutic light assembly of claim 22, wherein the inner panel includes an aperture at least partially aligned with the therapeutic light source configured to allow the therapeutic light source to shine through the inner panel.

24. The therapeutic light assembly of claim 23, wherein a conduit is defined between the inner panel and the outer panel, and further comprising an evacuator operatively connected to the housing and in fluid communication with the conduit and the critical treatment site or the open surgical site via the aperture, wherein the evacuator is configured and adapted to evacuate untreated air or smoke from the critical treatment site or the open surgical site.

25. The therapeutic light assembly of claim 24, further comprising a filter defined in the evacuator configured to filter the untreated air or smoke evacuated from the critical treatment site or the open surgical site.

26. The therapeutic light assembly of claim 25, wherein the evacuator includes an air mover configured to draw the untreated air or smoke evacuated from the critical treatment site or the open surgical site through the filter and to an outlet of the evacuator.

27. The therapeutic light assembly of claim 25, wherein the evacuator is configured and adapted to connect to an external vacuum source to draw the untreated air or smoke evacuated from the critical treatment site or the open surgical site through the filter and to the external vacuum source.

28. The therapeutic light assembly of claim 25, wherein the housing is arc shaped about the housing axis and defining a first leg portion, a second leg portion, and a top portion extending between the first side and the second side, wherein with the housing axis parallel to a vertical axis of the patient, the housing is configured to surround the patient on three sides and at least the top portion is configured to be placed directly over the critical treatment site or the open surgical site.

29. The therapeutic light assembly of claim 28, wherein the evacuator is operatively connected to the housing on the top portion.

30. The therapeutic light assembly of claim 29, wherein the therapeutic light source includes a plurality of therapeutic light sources and wherein the aperture defined in the inner panel includes a plurality of apertures defined in the inner panel, each aperture aligned with a respective therapeutic light source, wherein the conduit defined between the inner panel and the outer panel extends along an entirety of the first leg portion, the second leg portion, and the top portion of the housing such that the evacuator is in fluid communication with the critical treatment site or the open surgical site via each of the plurality of apertures defined in the inner panel.

31. The therapeutic light assembly of claim 25, wherein the housing is a closed shape extending about the housing axis, and wherein with the housing placed on the patient such that the housing axis is parallel to a sagittal axis of the patient, the housing is configured to fully surround the critical treatment site or the open surgical site.

32. The therapeutic light assembly of claim 31, wherein the closed shape is a rectangular shape having a first side and a second side opposite from one another, and a third side and fourth side extending between the first side and the second side, wherein the evacuator is defined in the first side.

33. The therapeutic light assembly of claim 32, wherein the therapeutic light source includes a plurality of therapeutic light sources and wherein the aperture defined in the inner panel includes a plurality of apertures defined in the inner panel, each aperture aligned with a respective therapeutic light source, wherein the conduit defined between the inner panel and the outer panel extends along an entirety of the first side, the second side, the third side, and the fourth side of the housing such that the evacuator is in fluid communication with the critical treatment site or the open surgical site via each of the plurality of apertures defined in the inner panel.

34. The therapeutic light assembly of claim 22, wherein the therapeutic light source includes a plurality of therapeutic light sources and wherein the aperture defined in the inner panel includes a plurality of apertures defined in the inner panel, each aperture aligned with a respective therapeutic light source.

35. The therapeutic light assembly of claim 34, wherein the housing is arc shaped about the housing axis and defining a first leg portion, a second leg portion, and a top portion extending between the first leg portion and the second leg portion, wherein the plurality of therapeutic light sources and the plurality of apertures are located in each of the first leg portion, the second leg portion, and the top portion, wherein with the housing axis parallel to a vertical axis of the patient, the housing is configured to surround a patient on three sides and at least the top portion is configured to be placed directly over the critical treatment site or the open surgical site.

36. The therapeutic light assembly of claim 34, wherein the housing is a closed shape extending about the housing axis, wherein with the housing placed on the patient such that the housing axis is parallel to a sagittal axis of the patient, the housing is configured to fully surround the critical treatment site or the open surgical site, wherein the plurality of therapeutic light sources and the plurality of apertures are located in all sides of the closed shape.

37. The therapeutic light assembly of claim 36, wherein the closed shape is a rectangular shape having a first side and a second side opposite from one another, and a third side and fourth side extending between the first side and the second side, wherein the plurality of therapeutic light sources and the plurality of apertures are located in each of the first side, the second side, the third side, and the fourth side.

38. The therapeutic light assembly of claim 34, wherein the plurality of therapeutic light sources includes a plurality of UV LEDs associated with a circuit board within the housing, wherein the plurality of UV LEDs are grouped into strips, wherein each strip includes between 3 or 4 LEDS, wherein the strips are around the housing circumferentially about the housing axis.

39. The therapeutic light assembly of claim 22, further comprising an optical lens in optical communication with the therapeutic light source configured to focus or redirect the therapeutic light to the critical treatment site or the open surgical site.
