Abstract
A solution for illuminating an area and/or treating a substance with light, such as ultraviolet radiation, is described. The solution can use one or more solid state ultraviolet sources in conjunction with one or more ultraviolet lamps to illuminate a treatment region with ultraviolet radiation. A control component can individually operate the solid state ultraviolet source(s) and the ultraviolet lamp(s) to illuminate the treatment region with ultraviolet radiation having a predetermined minimum ultraviolet intensity.
Claims20
A system comprising:
- a set of ultraviolet transparent windows defining at least a portion of at least one side of a treatment region;
- a set of solid state ultraviolet sources configured to emit ultraviolet light directed through an ultraviolet transparent window of the set of ultraviolet transparent windows into the treatment region;
- a set of ultraviolet lamps configured to emit ultraviolet light directed through an ultraviolet transparent window of the set of ultraviolet transparent windows into the treatment region;
- and
- a control component configured to individually operate the set of solid state ultraviolet sources and the set of ultraviolet lamps to treat a substance located within the treatment region by illuminating the treatment region with ultraviolet radiation having a predetermined minimum ultraviolet intensity, wherein the control component illuminates the treatment region by concurrently turning on the set of solid state ultraviolet sources and the set of ultraviolet lamps and reducing power to the set of solid state ultraviolet sources over time in response to the set of ultraviolet lamps emitting a higher intensity of ultraviolet radiation.
