Abstract
The invention relates to a light-diffusing material, having a high transmission of UVA light, useful for horticultural lighting. The light-diffusing material has a hiding power of greater than 50% at 350 nm and a transmission of light at 350 nm of at least 30 percent, and preferably at least 50%. Additionally the light-diffusing material also transmits and diffuses at least 50% of light at 300 nm, 465 nm, and at 800 nm. The light-diffusing material is especially useful as a glazing for horticultural use.
Claims17
A unit for horticultural production, comprising at least one sheet of a diffusing composition and at least one LED light engine,
- wherein the diffusing sheet or film is positioned between the LED light engine and at least one plant and has a hiding power of ±30 across the spectrum 300 nm-1000 nm,
- wherein the diffusing composition comprises a transparent or translucent polymer matrix, transmits at least 30 percent of UVB light at 300 nm, and transmits at least 50% of the UVA light at each of 350 nm 465 nm, 665 nm and 800 nm, and
- wherein the diffusing composition has a level of diffusion, as measured by hiding power, of at least 25 percent.
