An ultraviolet radiation blocking sheet for blocking ultraviolet radiation while allowing passage of visible light includes a film that is substantially transparent to light that has a wavelength of 495 to 570 nanometers. The film also is substantially absorbent of light that has a wavelength shorter than 495 nanometers. The film is configured to position between a light source and an object to be protected from ultraviolet radiation. The film absorbs the ultraviolet radiation emitted from the light source while allowing light that has a wavelength of 495 to 570 nanometers to pass through the film to illuminate the object.

The disclosure relates to ultraviolet radiation blocking devices and more particularly pertains to a new ultraviolet radiation blocking sheet for blocking ultraviolet radiation while allowing passage of visible light.
An embodiment of the disclosure meets the needs presented above by generally comprising a film that is substantially transparent to light that has a wavelength of 495 to 570 nanometers. The film also is substantially absorbent of light that has a wavelength shorter than 495 nanometers. The film is configured to position between a light source and an object to be protected from ultraviolet radiation. The film absorbs the ultraviolet radiation emitted from the light source while allowing light that has a wavelength of 495 to 570 nanometers to pass through the film to illuminate the object.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
FIG. 1 is an isometric perspective view of an ultraviolet radiation blocking sheet according to an embodiment of the disclosure.
FIG. 2 is an isometric perspective view of an embodiment of the disclosure.
With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new ultraviolet radiation blocking devices embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 5, the ultraviolet radiation blocking sheet 10 generally comprises a film 12 that is substantially transparent to light that has a wavelength of 495 to 570 nanometers. The film 12 also is substantially absorbent of light that has a wavelength shorter than 495 nanometers. In one embodiment, the film 12 also is substantially absorbent of light having a wavelength longer than 570 nanometers. In another embodiment, the film 12 is semi-rigid, such that the film 12 is formable into a container 14.
The container 14 has a bottom 16, an open top 18 and an annular wall 20 that define a holding space 22. The container 14 is configured to house the root system of a plant within the holding space 22 while allowing the root system to be inspected through the annular wall 20 and the bottom 16. The bottom 16 is circularly shaped. The open top 18 is dimensionally larger than the bottom 16, such that the container 14 is conical.
