| 摘要 |
This invention provides for a removable/replaceable, wavelength-transforming sleeve/sheath to be placed around a primary UV radiation source that emits a primary UV wavelength spectral distribution; such that at least a portion of the sleeve/sheath transforms at least a portion of the primary UV wavelength spectral distribution to a different secondary wavelength spectral distribution. Additionally, the sleeve/sheath may help to prevent breakage of the primary UV radiation source and to contain the broken pieces in the event of breakage. In some embodiments, a portion of the sleeve/sheath may be coupled with a UV reflective surface to direct radiation in a preferred direction. Individual sleeves/sheaths may have various patterns of wavelength-transforming materials that emit one or more secondary wavelength spectral distributions and the sleeve/sheath may also have one or more sections that allow transmission of the primary UV wavelength spectral distribution.
