To capitalize on the benefits of nanofiber technologies in solid-state lighting, several new remote phosphor reflector configurations were developed in the project. When combined with these unique lighting designs, nanofibers have a number of demonstrated benefits in lighting devices including:
- Providing high quantum efficiency down-conversion of LED wavelengths to produce full spectrum white light;
- Enabling tunable device structures that achieve colors ranging from warm white to cool white with high color rendering indexes (CRI);
- Supplying mass producible, cost-effective solutions for diffuse, high-reflectance light management across the visible spectrum;
- Facilitating remote phosphor luminaire designs that increase the lifetime and performance of luminescent materials;
- Providing conformability to geometries imposed by the light fixture enabling new lighting designs.
The technologies developed during this program have significant commercial potential, and there has been strong interest in these breakthroughs from the lighting community. It is anticipated that these technologies will begin appearing in commercial products in roughly five years.
This work was done by researchers at RIT International, with teaming members at Donaldson Company, Fujifilm Dimatix, Evident Technologies, and Elmarco USA.
